PART I

ITEM 1.  BUSINESS

Overview

We are

Timber Pharmaceuticals, Inc. (“Timber”, the “Company”, “we”, “us”) is a specialty pharmaceuticalclinical-stage biopharmaceutical company focused on utilizing ourthe development and commercialization of treatments for orphan dermatologic diseases. Our investigational therapies have proven mechanisms-of-action backed by decades of clinical experience and well-established CMC (chemistry, manufacturing and control) and safety profiles. We are initially focused on developing non-systemic treatments for rare dermatologic diseases including congenital ichthyosis, facial angiofibromas (“FAs”) in tuberous sclerosis complex (“TSC”), and scleroderma. Our lead programs are TMB-001, TMB-002 and TMB-003.

TMB-001, a proprietary drug delivery technologiestopical formulation of isotretinoin, is currently being evaluated in a Phase 2b clinical trial for the treatment of moderate to developsevere subtypes of congenital ichthyosis (“CI”), a group of rare genetic keratinization disorders that lead to dry, thickened, and commercialize novel prescription and over‑the‑counter, or OTC, products that address large markets in dermatology and women’s health. Our objective is to develop products that treat health or age‑related conditions that: (1) are not presently being addressed or treated or (2) are currently treatedscaling skin. A prior Phase 1/2 study involving 19 patients with drug therapies or drug delivery approaches that are sub‑optimal. Our strategy is designed to bring new products to market by identifying optimal delivery mechanisms and/or alternative applications for United States Food and Drug Administration, or FDA, approved active pharmaceutical ingredients, or APIs, and biological materials, while, in appropriate circumstances, reducing the time, cost and risk typically associated with new product development by repurposing drugs withCI demonstrated safety profiles and when applicable, taking advantagepreliminary efficacy of TMB-001, as well as minimal systemic absorption. In 2018, the FDA awarded us the first tranche of a $1.5 million grant in the amount of $500,000 to support clinical trials evaluating TMB-001 through its Orphan Products Grant program. In March 2020 and March 2021, the FDA awarded us the second and third tranches of the regulatory approvalgrant, respectively, each in the amount of $500,000.

TMB-002, a proprietary topical formulation of rapamycin, is currently being evaluated in a Phase 2b clinical trial for the treatment of FAs in TSC, a multisystem genetic disorder resulting in the growth of hamartomas in multiple organs. TSC results from dysregulation in the mTOR pathway, under Section 505(b)(2)and as a topical mTOR inhibitor, TMB-002 may address FAs in TSC without the systemic absorption of an oral agent.

TMB-003, a proprietary formulation of sitaxsentan, a new chemical entity in the U.S., which is a selective endothelin-A receptor antagonist, is currently in preclinical development as a locally applied formulation for the treatment of scleroderma, a rare connective tissue disorder characterized by abnormal thickening of the Federal Food, Drug,skin.

In connection with the Merger (as defined below), we acquired the BPX-01 and Cosmetic Act, or FDC Act. Section 505(b)(2) permits an applicant forBPX-04 assets. BPX-01 is a new product, such as a new or improved formulation or a new use of an approved product, to rely in part on literature and/or the FDA’s findings of safety and/or effectiveness for a similar previously‑approved product. We believe these approaches may reduce drug development risk and could reduce the time and resources we spend during development. Our current platform technologies include innovative delivery mechanisms for antibiotics, biologic materials and molecular iodine (I₂).

The product candidates in our current portfolio target significant market opportunities and include three clinical‑stage product candidates, BPX01, aPhase 3 ready topical antibioticminocycline for the treatment of inflammatory lesions of acne based on a unique formulation of minocycline, BPX04, a topical antibiotic for the treatment of inflammatory lesions of rosacea,vulgaris, and BPX03, a molecular iodine (I₂) tablet for the treatment of benign breast pain associated with fibrocystic breast condition, or FBC, and cyclic mastalgia, as well as one development‑stage product candidate, BPX02, an injectable product utilizing biological materials for aesthetic dermatology applications. We presented comprehensive BPX01 Phase 2b clinical data for the treatment of acne and received positive FDA feedback regarding our BPX01 Phase 3 clinical study plans. We are considering strategic partnership alternatives to fund our Phase 3 clinical program in this indication. We expect to beginBPX-04 is a Phase 3 clinical trial, should we raise the necessary additional capital or enter into a strategic partnership to fund the trial. A Phase 2 study for BPX04 in rosacea is currently in the planning stage, with study initiation expected in the second quarter of this year. We have initiated a pre‑Phase 2 feasibility study of BPX04 for the treatment of rosacea. We conducted an interim analysis of 19 subjects who have completed a 12‑week pre-Phase 2 feasibility study in the BPX04 for rosacea study, which suggested good tolerability and promising efficacy of BPX04 for this indication. The molecular iodine project includes a marketed OTC dietary supplement version, or VI₂OLET, for the alleviation of symptoms of FBC, as well as an investigational prescription drug version for the treatment of moderate to severe, periodic breast pain associated with FBC and cyclic mastalgia.

Products, Delivery Systems and Product Candidates

We have developed our product portfolio using our proprietary drug delivery technologies, including innovative delivery mechanisms for antibiotics, biologic materials and molecular iodine. We currently have one marketed product, our VI₂OLET iodine dietary supplement, three clinical‑stage product candidates, BPX01, BPX03 and BPX04, and one development‑stage product candidate, BPX02. The following table presents a summary of our marketed product and product candidates:

Iodine Delivery System

VI₂OLET Iodine

VI₂OLET, is an OTC molecular iodine dietary supplement that addresses cyclic breast discomfort and is clinically demonstrated to selectively deliver iodine to breast tissue, which helps to alleviate the symptoms associated with FBC, including tenderness, aches and swelling. Women who suffer from menstrual‑related breast discomfort are recommended to take one to two tablets per day on an empty stomach for at least 60 days to realize initial symptom relief. Our molecular iodine formula is delivered to breast tissue and is intended to reduce the fibrocystic changes that results in breast discomfort caused by such fibrocystic changes. We commercially launched VI₂OLET in December 2014 in online stores and have expanded into approximately 7,000 retail pharmacies, specialty chain outlet and grocery chain outlet stores throughout the United States. We recently entered into an agreement to distribute VI₂OLET in Mexico and Central America. We are exploring commercial growth opportunities for the expansion of VI₂OLET revenue, which may include strategic partnerships and/or sublicense with women’s and/or consumer health companies. To date, we have generated a de minimus amount of revenue from product sales.

BPX03 and Iodine Research

BPX03 is a prescription drug version of our molecular iodine tablet for the treatment of moderate to severe, periodic breast pain associated with FBC and cyclic mastalgia. We in‑licensed this prescription iodine drug candidate, which was previously under development by the licensors, and refer to both the prior sponsor’s investigational drug and our investigational drug as BPX03. We completed a clinical trial (using VI₂OLET) under Health Canada and institutional review board oversight to provide additional insight on how to design a Phase 3 safety and efficacy clinical trial. We are currently seeking a partner(s) to pursue any necessary clinical development and additional regulatory approvals for the product using the learnings from that clinical trial.

Hydrophilic Topical Delivery System

Ourready topical delivery system uses an anhydrous hydrophilic gel formulation that allows for the stabilization, solubilization and rapid absorption of API into the skin rather than remaining on the surface, a common problem with oil‑based ointments and suspensions. The first expression of this delivery system’s capabilities is demonstrated with minocycline.  The nature of the platform design makes it suitable for multiple APIs.

BPX01 - Acne

BPX01 is a hydrophilic topical antibiotic gel for the treatment of inflammatory lesions of acne, which combines the most widely used oral antibiotic drug (minocycline) for the treatment of inflammatory acne with a proprietary anhydrous hydrophilic topical delivery system specifically designed to localize the delivery of the drug while minimizing systemic exposure and the resultant side effects. This proprietary topical delivery system allows a lower dosage of drug by improving the bioavailability with enhanced and targeted delivery of fully solubilized minocycline. In addition to its bacteriostatic properties, the API, minocycline, also has anti‑inflammatory properties, which may help to reduce the swelling and redness commonly associated with acne.

We completed a Phase 2b randomized, double‑blind, three‑arm, vehicle‑controlled, dose‑finding study to assess the efficacy and safety of BPX01 for the treatment of acne. The multi‑center study evaluated two concentrations of BPX01 (1% and 2% minocycline) and vehicle in 226 subjects, aged 9 to 40, with moderate‑to‑severe inflammatory, non‑nodular acne. The study showed the 2% concentration was statistically superior in reducing the number of inflammatory lesions in patients with moderate‑to‑severe acne, compared to vehicle (59% reduction vs. 44%, respectively, at week 12, p=0.03).

This Phase 2b study also measured improvement on a five‑point investigator’s global assessment (IGA) scale. 25% of subjects treated with BPX01 2% showed at least a two‑grade improvement and an IGA of clear (0) or almost clear (1), a secondary efficacy endpoint in the study, compared to 17.6% for vehicle (p=0.54). Although the study was not powered to measure statistical significance for improvement in IGA, a clear numerical trend was observed in the BPX01 2% arm compared to vehicle. IGA was included as a secondary endpoint in our Phase 2b study as this information supports dose selection and is necessary to calculate sample size estimates to adequately power the Phase 3 studies for success. Since FDA guidance for the approval of topical prescription acne products recommends IGA as a co‑primary endpoint along with a reduction in absolute lesion counts for Phase 3 trials to support a New Drug Application, or NDA, the planned Phase 3 studies will be powered to demonstrate statistical significance of IGA improvement with at least a two‑grade improvement and a score of clear or almost clear for drug compared to vehicle as well as being powered to show a reduction in inflammatory lesion counts.

Researchers also found that no subjects experienced serious treatment‑related adverse side effects. Random blood draws in this study showed that plasma minocycline levels following topical use were undetectable in all but a single subject, whose level – 42 ng/mL – was less than one‑tenth of that measured after a single standard adult dosage of oral minocycline.

BPX04 – Rosacea

BPX04 is a hydrophilic topical antibiotic gel with fully soluble minocycline for the treatment of inflammatory lesions ofpapulopustular rosacea. We initiatedwill seek to monetize these assets through a 30 subject, single center, open‑label pre‑Phase 2 feasibility study of BPX04 to assesslicense, co-development, or sale.

On May 18, 2020, BioPharmX Corporation (“BioPharmX”) completed its business combination with Timber Pharmaceuticals LLC, a Delaware limited liability company (“Timber Sub”), in accordance with the safety and efficacy of BPX04 at 0% (vehicle), 1% and 2% minocycline for the treatment of rosacea. An interim analysisterms of the 19 subjects who have completedAgreement and Plan of Merger and Reorganization, dated as of January 28, 2020 (the “Merger Agreement”), by and among BioPharmX, Timber Sub and BITI Merger, Inc., a Delaware corporation and wholly-owned subsidiary of the 12‑week feasibility study suggests good tolerabilityCompany (“Merger Sub”), as amended by Amendment No. 1 thereto made and promising efficacyentered into as of BPX04 for this indication. Lesion countsMarch 24, 2020 (the “First Amendment”) and Amendment No. 2 thereto made and entered into as of April 27, 2020 (the “Second Amendment”) (the Merger Agreement, as amended by the First Amendment and the Second Amendment, the “Amended Merger Agreement”), pursuant to which Merger Sub merged with and into Timber Sub, with Timber Sub surviving as a wholly-owned subsidiary of the Company (the “Merger”). In connection with, and immediately prior to the completion of, the Merger, BioPharmX effected a reverse stock split of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at a ratio of 1-for-12 (the “Reverse Stock Split”). Immediately after completion of the Merger, BioPharmX changed its name to “Timber Pharmaceuticals, Inc.” and the officers and directors of Timber Sub became the officers and directors of the Company.

Under the terms of the Amended Merger Agreement, BioPharmX issued shares of Common Stock to the holders of common units of Timber Sub. Immediately after the Merger, there were reducedapproximately 11,849,031 shares of Common Stock outstanding (after the Reverse Stock Split). Pursuant to the terms of the Amended Merger Agreement, the former holders of common units of Timber Sub (including the Investors, as defined below, but excluding VARs, as defined below) owned in the 1% and 2% minocycline treatment arms by a mean of 90% at 12 weeks compared to baseline and 89%aggregate approximately 88.5% of the subjects demonstratedoutstanding Common Stock, with the Company’s stockholders immediately prior to the Merger owning approximately 11.5% of the outstanding Common Stock. The number of shares of Common Stock issued to the holders of common units of Timber Sub for each common unit of Timber Sub outstanding immediately prior to the Merger was calculated using an improvementexchange ratio of approximately 629.57 shares of Common Stock for each Timber Sub unit. In addition, the 584 Value Appreciation Rights of Timber Sub (“VARs”) that were outstanding immediately prior to Merger became denoted and payable in IGA scores367,670 shares of Common Stock at the effective time of the Merger (the “Effective Time”). Further, the holder of the 1,819,289 preferred units of Timber Sub outstanding immediately prior to clear (0)the Merger received 1,819 shares of the newly created convertible Series A preferred stock (the “Series A Preferred Stock”) at the Effective Time.

In connection with the Merger Agreement, on March 27, 2020, Timber Sub and BioPharmX entered into a securities purchase agreement (the “Securities Purchase Agreement”), with certain accredited investors (the “Investors”) pursuant to which, among other things, we issued to the Investors shares of Timber Sub units immediately prior to the Merger and BioPharmX issued to the Investors warrants to purchase shares of BioPharmX common stock on the tenth trading day following the consummation of the Merger (the “Investor Warrants”) in a private placement transaction for an aggregate purchase price of approximately $25 million (which amount is comprised of (x) approximately $5 million credit with respect to the senior secured promissory notes (the “Bridge Notes”) issued in connection with the bridge loan that certain of the Investors at the time of the execution of the Merger Agreement and (y) $20 million in cash from the Investors) (the “Purchase Price���). We issued to the Investors 8,384,764 Series A Warrants to purchase shares of Common Stock (“Series A Warrants”) and 7,042,175 Series B Warrants to purchase shares of Common Stock (“Series B Warrants”). At the time of issuance, the Series A Warrants had a 5-year term and an exercise price of $2.7953, subject to the number of shares and exercise price being reset based on our stock price after the Merger. The Series B Warrants had an exercise price per share of $0.001, were exercisable upon issuance and were initially convertible into 7,042,175 shares of Common Stock in the aggregate. The number of shares of Common Stock issuable pursuant to the Series B Warrants was also subject to adjustment based on specified reset prices.

In addition, pursuant to the terms of the Securities Purchase Agreement, on May 22, 2020 we issued to the Investors warrants to purchase 413,751 shares of Common Stock (the “Bridge Warrants”) which have an exercise price of $2.2362 per share.

On November 19, 2020, the Company entered into a Warrant Waiver Agreement with each of the Warrant holders which modified the terms of the original agreement and eliminated further resets. The aggregate number of Series A Warrants issued was fixed at 20,178,214 and the warrant exercise price was fixed at $1.16. The aggregate number of Series B Warrants was fixed at 22,766,777. The exercise price of the Series B Warrants remained unchanged.  

In addition, certain restrictions contained in the Warrant Agreement and Securities Purchase Agreement were modified including restrictions on the Company’s ability to issue additional equity securities in connection with a financing and the Company’s ability to complete a fundamental transaction. Subject to certain restrictions detailed in the Warrant Waiver Agreement, the Company is now able to complete an equity financing or almost clear (1) compareda fundamental transaction at any time after April 30, 2021.

Further, in connection with the Warrant Waiver Agreement the Company agreed to their baseline scoresimmediately register 11,383,389 shares of moderate (3) or severe (4)common stock issuable upon exercise of the Series B Warrants. The Warrant holders have additional demand registration rights as described in the Warrant Waiver Agreement. As of March 4, 2021, the Series B Warrants were exercised in full. As of March 15, 2021, 16,701,824 shares of common stock remain issuable upon exercise of the Series A Warrants.

We have a limited operating history as the Company was formed on February 26, 2019. Since inception, our operations have focused on establishing its intellectual property portfolio, including acquiring rights to the proprietary formulations of isotretinoin, rapamycin and sitaxsentan, as described above, organizing and staffing the Company, business planning, raising capital, and conducting clinical trials. Since inception, we have financed our operations with no serious drug‑related adverse events.$18.9 million through capital contributions

Since inception, we have incurred significant operating losses. For the period from February 26, 2019 (inception) to December 31, 2020, our net loss was $18.2 million. As of December 31, 2020, we had an accumulated deficit of $18.2 million. We expect to complete this 30 subject study incontinue to incur significant expenses and operating losses for the second half of this year, and also expect to initiate a Phase 2 study in the second quarter of this year.

In addition to BPX01 and BPX04, early data suggestsforeseeable future. We anticipate that our anhydrous hydrophilic topical delivery system may also be utilized with other APIs, including other antibiotics, retinoids and combinations.

Injectable Delivery System

Our injectable delivery system allows for prolonged release of biologics, as well as, small and mid‑sized molecules.

BPX02

We are developing BPX02, an injectable product utilizing biologic materials for aesthetic dermatology applications. This research stage product candidate is currently under internal development. Weexpenses will likely pursue

regulatory approval for this product via a biologics license application, or BLA. As such, BPX02 would still be subject to regulation under the FDC Act, except the section of the FDC Act that governs the approval of NDAs. Instead, BPX02 would be subject to the marketing and exclusivity provisions of the Public Health Service Act  for approval of BLAs. However, the application process and requirements for approval of BLAs are very similar to those for NDAs.

Encapsulation Delivery System

Our encapsulation delivery system is able to isolate the hydrophilic agent from the boundary layer between the hydrophlic and hydrophobic phases of emulsion. The emulsion of the hydrophilic delivery vehicle makes it feel smooth to the touch. We believe this new platform technology is an innovative way of delivering combinations of ingredients to cosmeceutical products for new market innovations. We have three patents issuedincrease significantly in the United States.

Target Markets

We believe that the industry dynamics in the area of dermatology represent significant opportunities for innovative new products to emerge as solutions for unmet needs in multi‑billion dollar therapeutic categories. In particular, we believe that the dermatology market is a large specialty market with significant global patient demand, and that our focus on this market coupledconnection with our proprietary platform technologies should enable usongoing activities, as we continue to develop and commercialize attractive products within this category.the pipeline of programs.

The Acne Market

Acne is a common inflammatory skin condition considered a chronic disease with accompanying negative aesthetic and social impact on patients. Propionibacterium acnes (P. acnes) are normal inhabitants on human skin and have been implicated in the pathogenesis of inflammatory acne.Recent Developments

In

On July 1, 2020, we announced that all 11 sites across the United States alone, acne affects between 40 million and 50 million people each year accordingAustralia in the Phase 2b CONTROL study evaluating TMB-001 in patients with moderate to severe CI are currently enrolling patients. As of December 31, 2020, all sites participating in a Phase 2b clinical trial evaluating TMB-002 were opened and are currently enrolling patients. On March 15, 2021, we announced that 50% of patients in the Phase 2b clinical trial have been enrolled.

Pursuant to the American Academy of Dermatology. AccordingAmended Merger Agreement, BPX-01 (Topical Minocycline, 2%) and BPX-04 (Topical Minocycline, 1%) were added to SSR Health, a provider of health care focused investment research,the Timber portfolio. BPX-01 and BPX-04 are assets currently in development for acne accounted for approximately $3.8 billion in sales in 2015 ($2.2 billion topical, $1.6 billion oral). Due to extensive consolidation in the dermatology market over the past decade, 64% (or $2.4 billion) of the $3.8 billion in 2015 acne sales was generated by three major pharmaceutical companies: Allergan Plc. (Allergan), Almirall S.A. (Almirall)vulgaris and Valeant Pharmaceuticals International, Inc. (Valeant).

The Rosacea Market

Rosacea is a chronic dermatologic condition characterized by redness, stinging and inflammatory lesions primarily on the face. It has four subtypes including erythematotelangiectatic rosacea, papulopustular rosacea, phymatous rosacea,respectively. On July 22, 2020, we announced that we had received notice from the European Patent Office that it intends to grant a patent for the Company’s topical composition of pharmaceutical tetracycline (including minocycline) for dermatological use (European Patent Application No. 16714168.8) and ocular rosacea. Symptoms include dilated blood vessels, redness, swelling,the application subsequently issued on December 16, 2020 as EP 3273940. Patents covering the BPX-01 and acne‑like papules and pustules on the face. The biology of rosacea remains unclear, however it is thought to be an inflammatory disorder that involves immune responses and microorganisms.

Rosacea is estimated to affect more than 16 million peopleBPX-04 assets have previously been granted in the United States, alone, according to the National Rosacea Society. The rosacea market is estimated to be greater than $1.0 billion in the United States according to Symphony Health Services. Branded prescription product revenue was approximately $700 million in 2015 according to Torreya Insights, with more than 80% of this revenue being generated by a limited number of brands. The leading manufacturersSouth Africa and Australia, among other countries. We are Galderma S.A. (Galderma) and Bayer Healthcare (Bayer).

Strategy and Competitive Strengths

We believe that the strength ofcurrently evaluating our novel drug delivery system technologies and the expertise of our team in the areas of product development and commercialization for prescription products, are the core elements driving our company. The key elements of our corporate strategy and competitive advantages include the following:strategic options regarding these assets.

Technology and Intellectual Property

Overview

Our success depends in large part upon our ability to obtain and maintain proprietary protection for our products and platform technologies. Our goal is to develop an intellectual property portfolio that enables us to capitalize on the research and developmentOn September 15, 2020, we announced that we have performed to date and will perform in the future, particularly for each of the products in our development pipeline and each of the products we market. We rely onhad received a combination of patent, copyright, trademark and trade secret laws in the United States and other countries to obtain and maintain our intellectual property. We protect our intellectual property by, among other methods, filing for patent applications on inventions that are important to the development and conduct of our business with the United States Patent and Trademark Office, or USPTO, and its foreign counterparts.

We also rely on a combination of non‑disclosure, confidentiality and other contractual restrictions to protect our technologies and intellectual property. We require our employees and consultants to execute confidentiality agreements in connection with their employment or consulting relationships with us. We also require them to agree to disclose and assign to us all inventions conceived in connection with the relationship.

Patents

Patent protection is an important aspect of our product development process and we are actively developing intellectual property in‑house. We have a total of eight U.S. provisional and utility patent applications pending related to our topical compositions for dermatological conditions and novel iodine‑based technologies for women’s health. We have four issued patents.  Three of these patents address a microparticle drug delivery technology. One of these relates to BPX. We also have 21 pending international patent applications, 18 of which relate to BPX01, two of which address a microparticle drug delivery technology and one of which addresses an iodine technology. These international patent applications resulted from development of our unique formulations of minocycline and iodine and were filed according to local national laws or the Patent Cooperation Treaty.  Generally, a patent application filed according to the Patent Cooperation Treaty enables us to apply for patent protection for the invention(s) described in the application in individual countries within a specified period after filing the application. Generally, patents issued in the United States are effective for 20 years from the earliest non-provisional filing date, if the application from which the patent issues was filed on or after June 8, 1995 (otherwise the term is the longer of 17 years from the issue date and 20 years from the earliest non-provisional filing date). The duration of patent terms for non-U.S. patents is typically 20 years from the earliest corresponding national or international filing date.

On March 1, 2013, we entered into a collaboration and license agreement with Iogen LLC, or Iogen, to license certain patents, formulations, and know‑how relating to molecular iodine formulations. Our license is an exclusive, royalty‑bearing license agreement with the right to enforce and sublicense. These licensed patents have expiration dates of 2029.

Trademarks

We have applied for trademark protection for several trademarks in the United States. The USPTO has registered several of our trademarks: “VIOLET,” “VI₂OLET,” “BIOPHARMX,” “GET IT OFF YOUR CHEST,” “THE GIRLS HAVE SOMETHING TO SAY,” “SMARTER DRUG DELIVERY,” and the VI₂OLET logo.

We have also applied for trademark protection in three markets outside the United States. In the European Union, we have registered trademarks for “BIOPHARMX” and “VI₂OLET.” In China, we have a registered trademark for “BIOPHARMX” and the VI₂OLET logo.  In Mexico, we have applied for trademark protection for the VI₂OLET logo.

Research and Development

A core competency is providing the link between concept and commercialization through focused, practical product development based on innovative research. We employ highly‑qualified scientists and consultants specializing 

in our various product development areas. Research and development expenses for the years ended January 31, 2018 and 2017 were approximately $9.1 million and $10.2 million, respectively.

As a Silicon Valley‑based company, we are located in a region with many strong biotechnology and pharmaceutical companies, which have drawn a high caliber of scientists and scientific support staff to the region. While there is intense competition for this type of personnel, we believe our location will enable us to expand our product development and consultant resources as our business grows. Our location also provides us with convenient access to local formulation resources and preclinical testing facilities.

Manufacturing, Supply and Production

We utilize contract manufacturers to produce our products for commercial distribution. We have no plans to establish in‑house manufacturing capabilities for large‑scale production at this time.

We have a master service agreement in place with DPT Laboratories, Ltd., or DPT, to carry out the manufacturing of clinical supplies. DPT provides drug development services including formulation development, clinical and commercial manufacturing satisfying the FDA’s current good manufacturing practices, or cGMPs, analytical methods development and stability testing. Additionally, we have a master service agreement with Dow Development Laboratories, LLC, to conduct formulation and analytical development and stability studies, among other services.  We are evaluating a second vendor to carry out the manufacturing and testing of our clinical and commercial supplies.

We have in place a commercial supply agreement with UPM Pharmaceuticals, or UPM, a division of Gregory Pharmaceuticals Holdings, Inc. to manufacture and package our VI₂OLET dietary supplement tablets. UPM provides high‑quality drug development services including formulation development, clinical and commercial manufacturing satisfying the cGMPs, analytical methods development, and stability testing.  Our manufacturing agreement for VI₂OLET with UPM requires a minimum annual purchase of approximately $269,000 of iodine dietary supplement tablets.  This agreement expires in 2020, and we are required to purchase the minimum annual amount regardless of market demand.  The remaining minimum purchase commitment is $0.9 million through 2020.  We have not recorded an obligation for the minimum purchase amount remaining since we have not assessed that the obligation will not be serviced in the normal course of business based on our market demand analysis.  In the future, we may conclude that an obligation is required as the result of our market demand analysis and record such obligation.  The recording of such obligation would negatively impact the results of our operations in the period recorded.

Marketing, Sales & Distribution

Our team has experience in the commercialization of prescription products. We have experience in branding and launching products in the United States, Europe and Asia. Our team understands channel strategies that include branded generic and licensed product strategies.

While BPX01 continues through clinical development, we have commenced our go‑to‑market strategic planning for the product including, but not limited to, organizing a medical advisory board of dermatologists in the United States, educating physicians through publishing our preclinical and clinical results at several industry conferences and developing our pricing strategy. While our commercialization plan for BPX01 will largely depend on the nature of  the strategic partnership we enter into, following the successful enrollment of our Phase 3 clinical trial we will evaluate our needs and take steps toward building our sales, marketing and distribution infrastructure in anticipation of commercial launch. Although we continue to evaluate commercializing BPX01 directly in the United States, we may choose to pursue strategic partnerships to launch the product outside of the United States, pending the appropriate regulatory approvals in each country, in order to take advantage of well‑established sales, marketing and distribution networks established by leading pharmaceutical companies in such countries.  The same process will be considered as BPX04 advances through clinical trials.

VI₂OLET is sold through online stores, drug stores, grocery stores and specialty retail chains throughout the United States. We recently entered into an agreement to distribute VI₂OLET in Mexico and Central America, and the distributor is responsible for all marketing, sales and distribution activities. We are evaluating expanded or alternative channels for distributing the product by way of partnerships and/or sublicensing with women’s health and/or consumer health companies.  Should we sublicense VI₂OLET, the sublicensee would be responsible for all marketing, sales and distribution.

Customers

Potential customers for our products and product candidates include pharmaceutical companies, physician’s practices, including obstetricians and gynecologists, dermatologists and general practitioners, and retail customers via retail sales channels and/or pharmacy outlets.

Competition

Acne

While the acne market has a number of competitive products, BPX01 is being developed to combine the most successful oral antibiotic drug (minocycline) for the treatment of moderate‑severe acne with a targeted topical antibiotic technology specifically designed to localize the delivery of the drug while minimizing systemic side effects. At the present time, there is no FDA‑approved topical solution for this drug.

A number of approved prescription acne products currently exist in oral form such as isotretinoins, antibiotics, antimicrobials and oral contraceptives. These treatments are marketed by a number of large pharmaceutical and specialty pharmaceutical companies including, but not limited to: Allergan, Almirall, Dr. Reddy’s Laboratories Ltd., Galderma, Impax Laboratories, Lupin Pharmaceuticals, Inc., Mayne Pharma Group Limited (Mayne Pharma), Mylan N.V. (Mylan), Pfizer, Inc.,  Sun Pharmaceutical Industries, Ltd. (Sun Pharma), Teva Pharmaceutical Industries, Ltd. (Teva) and Valeant. Additionally, there are several prescription acne products that exist in topical form such as antibiotics, antimicrobials, azelaic acids, retinoids, or some combination of the two. These topical solutions are marketed by companies such as Allergan, Bayer, Galderma, Mayne Pharma, Mylan, Sun Pharma, Teva and Valeant. In addition to prescription acne therapies discussed above, there are numerous OTC products in the form of benzoyl peroxide and salicylic acid topical solutions available from various cosmetic and cosmeceutical companies such as Aveeno, Clean & Clear, Clearasil, Neutrogena and Proactiv.

Energy‑based devices have also been widely used by dermatologists, such as intense pulsed light, or IPL, by Ellipse, and a device, elos, by Syneron, that treats a combination of IPL and radiofrequency technologies. Combination drug‑device treatments such as photodynamic therapy, or PDT, with Blu‑U by Dusa Pharmaceuticals, has been used off‑label for treating acne, while the Blu‑U light source without its PDT drug has been indicated for acne treatment.

While there is no FDA‑approved topical minocycline solution for acne (or otherwise), we are aware of one competitive product currently in Phase 3 clinical trials.

Rosacea

Unlike the acne market, the rosacea market has a relatively limited number of available therapies. The challenge with current topical treatments is that skin with rosacea is easily aggravated by too much drug or an irritating vehicle.  BPX04 is designed to deliver the active, minocycline, into the skin without further irritating the skin.  While the cause of rosacea is unclear, there are various oral and topical medications to treat the condition, such as antibiotics, anti-parasitics, azelaic acids and alpha-A agonists. Current treatments are marketed by companies such as Allergan, Bayer, Galderma, Mylan, Perrigo Company Plc., Sun Pharma and Valeant.  In addition to prescription rosacea therapies, devices such as intense pulsed light and the pulsed dye laser can be helpful in treating telangiectasia and vascular erythema to some extent and also may reduce associated symptoms.

While there is no FDA-approved topical minocycline solution for rosacea (or otherwise), we are aware of two competitive products currently in Phase 2 and Phase 3 clinical trials.

FBC and Cyclic Mastalgia

In the area of women’s health, many companies sell supplements containing iodide salts for the purpose of addressing hypothyroidism as iodine replacement therapy. We believe our competitive advantage is our solid dose proprietary formulation that delivers molecular iodine in a stable manner, allowing the consumer to ingest orally and specifically to address breast symptoms. Addressing an underserved condition, we believe that VI₂OLET is an innovative product that provides a new treatment option for millions of women.

While there is no single, established standard of care for FBC and cyclic mastalgia, physicians have typically recommended a range of treatments from changes in diet, abstaining from caffeine and methylxanthine and nutritional supplements, such as gamma‑linolenic acid, for mild symptoms to prescription analgesics and hormone‑based therapies, such as contraceptives, Danocrine, Tamoxifen and Bromocriptine, for more severe symptoms.

Some limitations of competitive approaches to addressing FBC and/or cyclic mastalgia include serious and sometimes dangerous side effects caused by prescription drugs and the temporary nature of relief provided by analgesics. Because optimal non‑hormonal solutions do not exist, many women with this condition choose to live with chronic pain.

Government Regulation

In the United States, foods (including dietary supplements), drugs (including biological products), medical devices, cosmetics, tobacco products and radiation‑emitting products are subject to extensive regulation by the FDA. The FDC Act and other federal and state statutes and regulations govern, among other things, the manufacture, distribution and sale of these products. These laws and regulations prescribe criminal and civil penalties that can be assessed, and violation of these laws and regulations can result in enforcement action by the FDA and other regulatory agencies.

Regulation of Dietary Supplements 

The formulation, manufacturing, packaging, labeling, advertising, distribution and sale (hereafter, “sale” or “sold” may be used to signify all of these activities) of dietary supplements are subject to regulation by one or more federal agencies, primarily the FDA and the Federal Trade Commission, or the FTC, and to a lesser extent the Consumer Product Safety Commission, or the CPSC.

All facilities that manufacture, process, package, or store food for human consumption must register with the FDA as a food facility. A dietary supplement is considered a food under the FDC Act and FDA regulations. Food facility registrations must be updated biennially. The FDA annually schedules inspections at a number of registered food facilities to determine whether the inspected facilities are in compliance with food‑related FDA regulations.

The FDA, under the FDC Act, regulates the formulation, manufacturing, packaging, labeling, distribution and sale of food, including dietary supplements. The FTC regulates the advertising of these products. The National Advertising Division of the Council of Better Business Bureaus, or NAD, oversees an industry sponsored, self‑regulatory system that permits competitors to resolve disputes over advertising claims. The NAD has no enforcement authority of its own, but may refer matters that appear to violate the Federal Trade Commission Act, or FTC Act, or the FDC Act to the FTC or the FDA for further action, as appropriate.

Federal agencies, primarily the FDA and the FTC, have a variety of procedures and enforcement remedies available to them, including initiating investigations, issuing warning letters and cease and desist orders, requiring corrective labeling or advertising, requiring consumer redress (for example, requiring that a company offer to repurchase products previously sold to consumers), seeking injunctive relief or product seizures, imposing civil penalties or commencing criminal prosecution. In addition, certain state agencies have similar authority.

The Dietary Supplement Health and Education Act, or DSHEA, was enacted in 1994 and amended the FDC Act. DSHEA establishes a statutory class of dietary supplements, which includes vitamins, minerals, herbs, amino acids and other dietary ingredients for human use to supplement the diet. Among other things, DSHEA prevents the FDA from regulating dietary ingredients in dietary supplements as food additives. Dietary ingredients marketed in the United States before October 15, 1994 may be marketed without the submission of a new dietary ingredient, or NDI, premarket notification, or NDIN, to the FDA. Dietary ingredients not marketed in the United States before October 15, 1994 may require the submission, at least 75 days before marketing, of an NDIN containing information establishing that the ingredient is reasonably expected to be safe for its intended use. Among other things, DSHEA prevents the FDA from regulating dietary ingredients in dietary supplements as food additives.

The FDA issued an updated draft guidance document in August 2016 that clarifies when the FDA believes a dietary ingredient is an NDI, when a manufacturer or distributor must submit an NDIN to the FDA, the evidence necessary to document the safety of an NDI and the methods for establishing the identity of an NDI. The FDA’s interpretation of what constitutes an NDI subject to an NDIN is extremely broad and seems to imply that virtually every

new dietary supplement requires an NDIN. In addition, the FDA may begin to take enforcement actions consistent with the interpretations in the draft guidance before issuing a final version.

The FDA’s cGMPs regulations for dietary supplements apply to manufacturers and holders of finished dietary supplement products, including dietary supplements manufactured outside the United States that are imported for sale into the United States. Among other things, the FDA’s cGMPs: (a) require identity testing on all incoming dietary ingredients, (b) call for a scientifically valid system for ensuring finished products meet all specifications, (c) include requirements related to process controls, including statistical sampling of finished batches for testing and requirements for written procedures and (d) require extensive recordkeeping.

Under the Dietary Supplement and Nonprescription Drug Consumer Protection Act, the FDA requires, among other things, that companies that manufacture or distribute nonprescription drugs or dietary supplements report serious adverse events associated with their products to the FDA and institute recordkeeping requirements for all adverse events. Based on serious adverse event (or other) information, the FDA may take actions against dietary supplements or dietary ingredients that in its determination present a significant or unreasonable risk of illness or injury, which could make it illegal to sell those products. FDA publishes quarterly reports on serious adverse events it receives.

The FDA Food Safety Modernization Act, or FSMA, enacted January 4, 2011, amended the FDC Act to significantly enhance the FDA’s authority over various aspects of food regulation, including dietary supplements. Under FSMA, the FDA may use the mandatory recall authority when the FDA determines there is a reasonable probability that a food (including a dietary supplement) is adulterated or misbranded and that the use of, or exposure to, the food will cause serious adverse health consequences or death to humans or animals. Also under FSMA, the FDA has expanded access to records; the authority to suspend food facility registrations and require high risk imported food to be accompanied by a certification; stronger authority to administratively detain food; the authority to refuse admission of an imported food if it is from a foreign establishment to which a United States inspector is refusing entry for an inspection; and the authority to require that importers verify that the foods they import meet domestic standards.

The new FSMA requirements, as well as the FDA enforcement of the NDI draft guidance, can result in the detention and refusal of admission of imported products, the injunction of manufacturing of any dietary ingredients or dietary supplements until the FDA determines that such ingredients or products are in compliance, and the potential imposition of fees for re‑inspection of noncompliant facilities.

The FDC Act, as amended by DSHEA, permits statements of nutritional support often referred to as “structure/function claims” to be included in labeling for dietary supplements without FDA pre‑market approval. FDA regulation requires that FDA be notified of those statements within 30 days of marketing. Among other things, the statements may describe the role of a dietary ingredient intended to affect the structure or function of the body or characterize the documented mechanism of action by which a dietary ingredient maintains such structure or function, but may not expressly or implicitly represent that a dietary supplement will diagnose, cure, mitigate, treat, or prevent a disease. A company that uses a statement of nutritional support in labeling must possess information substantiating that the statement is truthful and not misleading. If the FDA determines that a particular statement of nutritional support is an unacceptable drug claim or an unauthorized version of a health claim, or if the FDA determines that a particular claim is not adequately supported by existing information or is otherwise false or misleading, the claim could not be used and any product bearing the claim could be subject to regulatory action.

The FTC and the FDA have pursued a coordinated effort to challenge the scientific substantiation for dietary supplement claims. Their efforts to date have focused on manufacturers and marketers as well as media outlets and have resulted in a significant number of investigations and enforcement actions, some resulting in civil penalties under the FTC Act of several million dollars. If the FTC and the FDA continue to focus on health related claims, including structure/function claims for dietary supplements, dietary supplements could be the subject of FTC and/or FDA inquiries, inquiries from NAD, and states attorneys general, as well as private class action lawsuits.

All states regulate foods and drugs under laws that generally parallel federal statutes. These products are also subject to state consumer health and safety regulations, such as California Safe Drinking Water and Toxic Enforcement Act of 1986, or Proposition 65. Violation of Proposition 65 may result in substantial monetary penalties.

FDA Regulation of Drugs

New Drug Approval Process

Pharmaceutical products are subject to extensive regulation by the FDA. The FDC Act, and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post‑approval monitoring and reporting, sampling, and import and export of pharmaceutical products. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs or BLAs, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties and criminal prosecution.

Pharmaceutical product development for a new product or certain changes to an approved product in the United States typically involves preclinical laboratory and animal tests, the submission to the FDA of an investigational new drug, or IND, which must become effective before clinical testing may commence, and adequate and well‑controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought. Satisfaction of FDA pre‑market approval requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity and novelty of the product or disease.

Preclinical tests include laboratory evaluation of product chemistry, formulation and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with federal regulations and requirements, including good laboratory practices. The results of preclinical testing are submitted to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls, and a proposed clinical trial protocol. Long term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

A 30‑day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND within this 30‑day period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the IND to healthy volunteers or patients under the supervision of a qualified investigator. Clinical trials must be conducted: (i) in compliance with federal regulations; (ii) in compliance with good clinical practice, or GCP, an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators, and monitors; as well as (iii) under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol and informed consent information for patients in clinical trials must also be submitted to an IRB for approval. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose other conditions.

Clinical trials to support NDAs or BLAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1, the initial introduction of the drug into healthy human subjects or patients, the drug is tested to assess metabolism, pharmacokinetics, pharmacological actions, side effects associated with increasing doses, and, if possible, early evidence on effectiveness. Phase 2 usually involves trials in a limited patient population to determine the effectiveness of the drug for a particular indication, dosage tolerance, and optimum dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations, Phase 3 trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit‑risk relationship of the drug and to provide adequate information for the labeling of the drug. In most cases the FDA requires two adequate and well‑controlled Phase 3 clinical trials to demonstrate the efficacy of the drug. A single Phase 3 trial with other confirmatory evidence may be sufficient in  instances where the study is a large multicenter trial demonstrating internal consistency and a statistically very

persuasive finding of a clinically meaningful effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically or ethically impossible.

In addition, the manufacturer of an investigational drug in a Phase 2 or Phase 3 clinical trial for a serious or life-threatening disease is required to make available, such as by posting on its website, its policy on evaluating and responding to requests for expanded access.

After completion of the required clinical testing, an NDA or BLA is prepared and submitted to the FDA. FDA approval of the NDA or BLA is required before marketing of the product may begin in the U.S. The NDA or the BLA must include the results of all preclinical, clinical and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture and controls. The cost of preparing and submitting an NDA is substantial. The submission of most NDAs and BLAs is additionally subject to a substantial application user fee, currently approximately $2,421,000 for fiscal year 2018.  Under an approved NDA or BLA, the applicant is subject to an annual program fee, currently approximately $304,000 per prescription product for fiscal year 2018. Beginning in fiscal year 2018, this annual program fee replaces the annual product and establishment fees.  These fees typically increase annually.

The FDA has 60 days from its receipt of an NDA or BLA to determine whether the application will be filed based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. If the NDA or BLA submission is filed, the FDA reviews the NDA or BLA to determine, among other things, whether the proposed product is safe and effective for its intended use. The FDA has agreed to certain performance goals in the review of NDAs or BLAs. Most such applications for standard review drug products are reviewed within ten to twelve months; most applications for priority review drugs are reviewed in six to eight months. Priority review can be applied to drugs that the FDA determines offer major advances in treatment, or provide a treatment where no adequate therapy exists. For biologics, priority review is further limited to drugs intended to treat a serious or life‑threatening disease relative to the currently approved products. The review process for both standard and priority review may be extended by the FDA for three additional months to consider certain late‑submitted information, or information intended to clarify information already provided in the submission.

The FDA may also refer applications for novel drug products, or drug products that present difficult questions of safety or efficacy, to an advisory committee – typically a panel that includes clinicians and other experts – for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. The FDA will not approve the product unless compliance with cGMPs is satisfactory and the NDA or BLA contains data that provide substantial evidence that the drug is safe and effective in the indication studied.

After the FDA evaluates the NDA or BLA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA or BLA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included.

An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. As a condition of NDA or BLA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability of the drug. Moreover, product approval may require substantial post‑approval testing and surveillance to monitor the drug’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or BLA supplement before the change can be implemented. An NDA or BLA supplement for a new indication typically requires

clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA or BLA supplements as it does in reviewing NDAs or BLAs.

Pediatric Information

Under the Pediatric Research Equity Act, or PREA, NDAs, BLAs or supplements to NDAs or BLAs must contain data to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective. The FDA may grant full or partial waivers, or deferrals, for submission of data. Unless otherwise required by regulation, PREA does not apply to any drug for an indication for which orphan designation has been granted, except a product with a new active ingredient that is a molecularly targeted cancer product intended for the treatment of an adult cancer and directed at a molecular target determined by FDA to be substantially relevant to the growth or progression of a pediatric cancer that is subject to an NDA or BLA submitted on or after August 18, 2020.

The Best Pharmaceuticals for Children Act, or BPCA, provides NDA holders a six‑month extension of any exclusivity – patent or non‑patent – for a drug if certain conditions are met. For BLAs, the BPCA provides a six‑month extension for non‑patent exclusivity if certain conditions are met. Conditions for exclusivity include the FDA’s determination that information relating to the use of a new drug in the pediatric population may produce health benefits in that population, the FDA making a written request for pediatric studies, and the applicant agreeing to perform, and reporting on, the requested studies within the statutory timeframe. Applications under the BPCA are treated as priority applications, with all of the benefits that designation confers.

Disclosure of Clinical Trial Information

Sponsors of clinical trials of FDA‑regulated products, including drugs, are required to register and disclose certain clinical trial information. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discuss the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed in certain circumstances for up to two years after the date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

The Hatch‑Waxman Amendments

Orange Book Listing

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent with claims covering the applicant’s product or method of using the product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application, or ANDA. An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been shown to be bioequivalent to the listed drug. Other than the requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, preclinical or clinical tests to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug, and can often be substituted by pharmacists under prescriptions written for the original listed drug.

The ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by the new product. The ANDA applicant may also elect to submit a section viii statement certifying that its proposed ANDA labeling does not contain (or carves out) any language regarding the patented method‑of‑use rather than certify to a listed method‑of‑use patent. If the applicant does not challenge the listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.

A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been received by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement

lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDAallowance from approving the ANDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit or a decision in the infringement case that is favorable to the ANDA applicant.

The ANDA application also will not be approved until any applicable non‑patent exclusivity listed in the Orange Book for the referenced product has expired.

Exclusivity

Exclusivity provisions under the FDC Act also can delay the submission or the approval of certain applications. The FDC Act provides a five‑year period of non‑patent exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity, or NCE. A drug is entitled to NCE exclusivity if it contains a drug substance no active moiety of which has been previously approved by the FDA. During the exclusivity period, the FDA may not accept for review an ANDA or file a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a Paragraph IV certification. The FDC Act also provides three years of market exclusivity for an NDA, including a 505(b)(2) NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages or strengths of an existing drug. This three‑year exclusivity covers only the conditions for use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs for the original conditions of use, such as the originally approved indication. Five‑year and three‑year exclusivity will not delay the submission or approval of a full NDA; however, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all the non‑clinical studies and adequate and well‑controlled clinical trials necessary to demonstrate safety and effectiveness.

Patent Term Extension

After NDA approval, the owner of relevant drug patent may apply for up to a five year patent term extension. Only one patent may be extended for each regulatory review period, which is composed of two parts: a testing phase, and an approval phase. The allowable patent term extension is calculated as half of the drug’s testing phase – the time between the day the IND becomes effective and NDA submission – and all of the review phase – the time between NDA submission and approval up to a maximum of five years. The time can be shortened if the FDA determines that the applicant did not pursue approval with due diligence. The total patent term after the extension may not exceed 14 years.

For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension increases the patent term by one year and may be renewed up to four times. For each interim patent extension granted, the post‑approval patent extension is reduced by one year. The director of the U.S. Patent and Trademark Office must determine(USPTO) for a Company patent application covering BPX-01 and BPX-04, our pharmaceutical tetracycline (including minocycline) compositions for dermatological use (U.S. Patent Application No.: 16/514,459) and the application subsequently issued on January 5, 2021 as US 10,881,672.

On December 15, 2020, we announced that approvalwe had received a notice of allowance from the USPTO for a Company patent application covering TMB-001, our pharmaceutical isotretinoin composition (U.S. Patent Application No.: 15/772,456) and the application subsequently issued on February 10, 2021 as US 10,933,018.

On January 12, 2021, we announced that the FDA has granted orphan drug designation for TMB-003, our locally delivered formulation of sitaxsentan, for the treatment of systemic sclerosis.

On January 25, 2021, we announced the appointment of Alan Mendelsohn, M.D., as Chief Medical Officer. Dr. Mendelsohn assumed the roles and responsibilities of Amir Tavakkol, Ph.D., who stepped down as our Chief Scientific Officer.

On March 17, 2021, we announced that AFT Pharmaceuticals Limited (“AFT”), one of our development partners, entered into a license and supply agreement with Desitin Arzneimittel GmbH (“Desitin”) for Pascomer® (TMB-002 topical rapamycin) for the treatment of FAs associated with TSC in Europe. Pursuant to the AFT Licensing and Development Agreement (as defined below), we are entitled to receive a significant percentage of the drug covered byeconomics (royalties and milestones) in any licensing transaction that AFT executes outside of North America, Australia, New Zealand, and Southeast Asia. The current transaction with Desitin is included in the patentscope of this provision.

Asset Purchase Agreements with Patagonia Pharmaceuticals LLC (“Patagonia”)

On February 28, 2019, we acquired the intellectual property rights for which a patent extensiontopical formulation of isotretinoin for the treatment of CI and identified as TMB-001, formerly PAT-001 including the IPEG^TM brand, from Patagonia (the “TMB-001 Acquisition”). Zachary Rome, our Executive Vice-President and Chief Operating Officer serves as President of Patagonia and also maintains an ownership interest therein.

Under the terms of the TMB-001 Acquisition, we paid a one-time upfront payment of $50,000 to Patagonia. Patagonia is entitled to up to $27.0 million of cash milestone payments relating to certain regulatory and commercial achievements of the TMB-001 Acquisition, with the first being sought$4.0 million from the initiation of a Phase 3 pivotal trial, as agreed with the FDA. In addition, Patagonia is likely. Interim patent extensionsentitled to net sales earn-out payments ranging from low single digits to mid-double digits for the program licensed. We are responsible for all development activities under the license. The potential regulatory and commercial milestones are not availableyet considered probable, and no milestone payments have been accrued at December 31, 2020.

On June 26, 2019, we acquired the intellectual property rights for a drug for which an NDA has not been submitted.

Section 505(b)(2) New Drug Applications

Most drug products obtain FDA marketing approval pursuant to an NDA or an ANDA. A third alternative is a special typelocally administered formulation of NDA, commonly referred to as a Section 505(b)(2), or 505(b)(2), NDA, which enables the applicant to rely, in part, on studies not conducted by, orsitaxsentan for the applicanttreatment of cutaneous fibrosis and/or pigmentation disorders, and for whichidentified as TMB-003, formerly PAT-S03, from Patagonia (the “TMB-003 Acquisition”).

Upon closing of the applicant has not obtainedTMB-003 Acquisition, we paid a rightone-time upfront payment of reference or use, such as$20,000 to Patagonia. Patagonia is entitled to up to $10.25 million of cash milestone payments subject to adjustments relating to certain regulatory and commercial achievements of the FDA’s findingsTMB-003 License, with the first being a one-time payment of safety and/or effectiveness for a similar previously approved product, or published literature, in support of its application.

505(b)(2) NDAs often provide an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. Section 505(b)(2) permits$250,000 upon the filingopening of an NDA where at least some ofIND with the information required for approval comesFDA. In addition, Patagonia is entitled to net sales earn-out payments ranging from studies not conducted by, orlow to mid-single digits for the applicant and for which the applicant has not obtained a right of reference. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new product candidateprogram licensed. We are responsible for all or some,development activities under the license. The potential regulatory and commercial milestones are not yet considered probable, and no milestone payments have been accrued at December 31, 2020.

Acquisition of the label indications forLicense from AFT Pharmaceuticals Limited (“AFT”)

On July 5, 2019, we entered into a license agreement with AFT which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant.

To the extent that the Section 505(b)(2) applicant is relying on studies conducted forprovides us with (i) an already approved product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would. Thus approval of a 505(b)(2) NDA can be stalled until all the listed patents claiming the referenced product have expired, until any non‑patent exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the referenced product has expired, and, in the case of a Paragraph IV certification and subsequent patent infringement suit, until the earlier of 30 months, settlement of the lawsuit or a decision in the infringement case that is favorable to the Section 505(b)(2) applicant.

Post‑Approval Requirements

Once an NDA or BLA is approved, a product will be subjectexclusive license to certain post‑approval requirements. For instance,licensed patents, licensed know-how and AFT trademarks to commercialize the FDA closely regulates the post‑approval marketing and promotion of drugs, including standards and regulations for direct‑to‑consumer advertising, off‑label promotion, industry‑sponsored scientific and educational activities and promotional activities involving the internet. Drugs may be marketed only for the approved indications and in accordance with the provisions of the approved labeling.

Adverse event reporting and submission of periodic reports are required following FDA approval of an NDA or BLA. The FDA also may require post‑marketing testing, known as Phase 4 testing, REMS, and surveillance to monitor the effects of an approvedPascomer® product or the FDA may place conditions on an approval that could restrict the distribution or use of the product. In addition, quality‑control, drug manufacture, packaging and labeling procedures must continue to conform to cGMPs after approval. Drug manufacturers and certain of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the FDA subjects entities to periodic unannounced inspections by the FDA, during which the agency inspects manufacturing facilities to assess compliance with cGMPs. Accordingly, manufacturers must continue to expend time, money and effort in the areas of production and quality‑control to maintain compliance with cGMPs. Regulatory authorities may withdraw product approvals or request product recalls if a company fails to comply with regulatory standards, if it encounters problems following initial marketing or if previously unrecognized problems are subsequently discovered. In addition, prescription drug manufacturers in the United States, must comply with applicable provisions ofCanada and Mexico and (2) a co-exclusive license to develop the Drug Supply Chain Security Act and provide and receive product tracing information, maintain appropriate licenses, ensure they only work with other properly licensed entities, and have procedures in place to identify and properly handle suspect and illegitimate products.

Biologics

Biological products used for the prevention, treatment or cure of a disease or condition of a human being are subject to regulation under the FDC Act, except the section of the FDC Act which governs the approval of NDAs. Biological products are approved for marketing under provisions of the Public Health Service Act, or PHSA, via a BLA. However, the application process and requirements for approval of BLAs are very similar to those for NDAs, and biologics are associated with similar approval risks and costs as drugs. To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of manufacturing controls for products whose attributes cannot be precisely defined. The PHSA also provides authority to the FDA to immediately suspend licenses in situations where there exists a danger to public health, to prepare or procure products in the event of shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or spread of communicable diseases in the United States and between states.

After a BLA is approved, the product may also be subject to official lot release as a condition of approval. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA may also perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products. As with drugs, after approval of biologics, manufacturers must address any safety issues that arise, are subject to recalls or a halt in manufacturing, and are subject to periodic inspection after approval.

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, creates an abbreviated approval pathway for biological products shown to be highly similar to or interchangeable with an FDA‑licensed reference biological product. Biosimilarity sufficient to reference a prior FDA‑approved product requires that there be no differences in conditions of use, route of administration, dosage form, and strength, and no clinically meaningful

differences between the biological product and the referencePascomer product in terms of safety, purity and potency. Biosimilarity must be shown through analytical studies, animal studies, and at least one clinical study, absent a waiver bythis territory. Concurrently, we granted to AFT an exclusive license to commercialize the Secretary. A biosimilar product may be deemed interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. To date, a handful of biosimilar products and no interchangeable products have been approved under the BPCIA. Complexities associated with the larger, and often more complex, structures of biological products, as well as the process by which such products are manufactured, particularly with respect to interchangeability, are still being evaluated by the FDA.

A reference biologic is granted twelve years of exclusivity from the time of first licensure of the reference product, and no application for a biosimilar can be submitted for four years from the date of licensure of the reference product. The first biologic product submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has exclusivity against a finding of interchangeability for other biologics for the same condition of use for the lesser of (i) one year after first commercial marketing of the first interchangeable biosimilar, (ii) eighteen months after the first interchangeable biosimilar is approved if there is no patent challenge, (iii) eighteen months after resolution of a lawsuit over the patents of the reference biologic in favor of the first interchangeable biosimilar applicant, or (iv) 42 months after the first interchangeable biosimilar’s application has been approved if a patent lawsuit is ongoing within the 42‑month period.

Regulation Outside the United States

In order to market anyPascomer product outside of its territory and co-exclusive sublicense to develop and manufacture the United States, a company must also comply with numerous and varying regulatory requirementslicensed product for commercialization outside of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of drug products. Whether or not it obtains FDA approval for a product, the Company would need to obtain the necessary approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product in those countries or jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.its territory (the “AFT License Agreement”).

Regulation and Marketing Authorization in the European Union

The process governing approval of medicinal products in the European Union, or E.U., follows essentially the same lines as in the United States and, likewise, generally involves satisfactorily completing each of the following:

Preclinical Studies

Preclinical tests include laboratory evaluations of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animal studies, in order to assess the potential safety and efficacy of the product. The conduct of the preclinical tests and formulation of the compounds for testing must comply with the relevant E.U. regulations and requirements. The results of the preclinical tests, together with relevant manufacturing information and analytical data, are submitted as part of the CTA.

Clinical Trial Approval

RequirementsAFT License Agreement also provides for the conduct of clinical trials in the European Union including GCP are implemented in the Clinical Trials Directive 2001/20/EC and the GCP Directive 2005/28/EC. Pursuant to Directive 2001/20/EC and Directive 2005/28/EC, as amended, a system for the approval of clinical trials in the European Union has been implemented through national legislation of the member states. Under this system, approval must be obtained from the competent national authority of an E.U. member state in which a study is planned to be conducted, or in multiple member states if the clinical trial is to be conducted in a number of member states. To this end, a CTA is submitted, which must be supported by an investigational medicinal product dossier, or IMPD, and further supporting information prescribed by Directive 2001/20/EC and Directive 2005/28/EC and other applicable guidance documents. Furthermore, a clinical trial may only be started after a competent ethics committee has issued a favorable opinion on the clinical trial application in that country.

In April 2014, the E.U. legislators passed the new Clinical Trials Regulation, (EU) No 536/2014, which will replace the current Clinical Trials Directive 2001/20/EC. To ensure that the rules for clinical trials are identical throughout the E.U., the new E.U. clinical trials legislation was passed as a regulation that is directly applicable in all E.U. member states. All clinical trials performed in the European Union are required to be conducted in accordance with the Clinical Trials Directive 2001/20/EC until the new Clinical Trials Regulation (EU) No 536/2014 becomes applicable.    According to the current plans of the European Medicines Agency, or EMA, the new Clinical Trials Regulation will become applicable in 2019. The Clinical Trials Directive 2001/20/EC will, however, still apply three years from the date of entry into application of the Clinical Trials Regulation to (i) clinical trials applications submitted before the entry into application and (ii) clinical trials applications submitted within one year after the entry into application if the sponsor opts for old system.

The new Regulation (EU) No 536/2014 aims to simplify and streamline the approval of clinical trial in the E.U. The main characteristics of the regulation include:

Marketing Authorization

Authorization to market a product in the member states of the European Union proceeds under one of four procedures: a centralized authorization procedure, a mutual recognition procedure, a decentralized procedure or a national procedure.

Centralized Authorization Procedure

The centralized procedure enables applicants to obtain a marketing authorization that is valid in all E.U. member states based on a single application. Certain medicinal products, including products developed by means of biotechnological processes, must undergo the centralized authorization procedure for marketing authorization, which, if granted by the European Commission, is automatically valid in all 28 E.U. member states. The EMA and the European Commission administer this centralized authorization procedure pursuant to Regulation (EC) No 726/2004.

Pursuant to Regulation (EC) No 726/2004, this procedure is mandatory for:

The centralized authorization procedure is optional for other medicinal products if they contain a new active substance or if the applicant shows that the medicinal product concerned constitutes a significant therapeutic, scientific or technical innovation or that the granting of authorization is in the interest of patients in the European Union.

Administrative Procedure

Under the centralized authorization procedure, the EMA’s Committee for Human Medicinal Products, or CHMP, serves as the scientific committee that renders opinions about the safety, efficacy and quality of medicinal products for human use on behalf of the EMA. The CHMP is composed of experts nominated by each member state’s national authority for medicinal products, with expert appointed to act as Rapporteur for the co‑ordination of the evaluation with the possible assistanceformation of a further member of the Committee acting as a Co‑Rapporteur. After approval, the Rapporteur(s) continuejoint steering committee to monitor the product throughout its life cycle. The CHMP has 210 days to adopt an opinion as to whether a marketing authorization should be granted. The process usually takes longer in case additional information is requested, which triggers clock‑stops in the procedural timelines. The process is complexoversee, coordinate and involves extensive consultation with the regulatory authorities of member statesreview recommendations and a number of experts. When an application is

submitted for a marketing authorizationapprove decisions in respect of a drug that is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation, the applicant may pursuant to Article 14(9) Regulation (EC) No 726/2004 request an accelerated assessment procedure. If the CHMP accepts such request, the time‑limit of 210 days will be reduced to 150 days but it is possible that the CHMP can revert to the standard time‑limit for the centralized procedure if it considers that it is no longer appropriate to conduct an accelerated assessment. Once the procedure is completed, a European Public Assessment Report, or EPAR, is produced. If the opinion is negative, information is given as to the grounds on which this conclusion was reached. After the adoption of the CHMP opinion, a decision on the MAA must be adopted by the European Commission, after consulting the E.U. member states, which in total can take more than 60 days.

Conditional Approval

In specific circumstances, E.U. legislation (Article 14(7) Regulation (EC) No 726/2004 and Regulation (EC) No 507/2006 on Conditional Marketing Authorizations for Medicinal Products for Human Use) enables applicants to obtain a conditional marketing authorization prior to obtaining the comprehensive clinical data required for an application for a full marketing authorization. Such conditional approvals may be granted for product candidates (including medicines designated as orphan medicinal products) if (1) the risk‑benefit balance of the product candidate is positive, (2) it is likely that the applicant will be in a position to provide the required comprehensive clinical trial data, (3) the product fulfills unmet medical needs and (4) the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still required. A conditional marketing authorization may contain specific obligations to be fulfilled by the marketing authorization holder, including obligations with respect to the completion of ongoing or new studies, and with respect to the collection of pharmacovigilance data. Conditional marketing authorizations are valid for one year, and may be renewed annually, if the risk‑benefit balance remains positive, and after an assessment of the need for additional or modified conditions and/or specific obligations. The timelines for the centralized procedure described above also apply with respect to the review by the CHMP of applications for a conditional marketing authorization.

Marketing Authorization under Exceptional Circumstances

Under Article 14(8) Regulation (EC) No 726/2004, products for which the applicant can demonstrate that comprehensive data (in line with the requirements laid down in Annex I of Directive 2001/83/EC, as amended) cannot be provided (due to specific reasons foreseen in the legislation) might be eligible for marketing authorization under exceptional circumstances. This type of authorization is reviewed annually to reassess the risk‑benefit balance. The fulfillment of any specific procedures/obligations imposed as part of the marketing authorization under exceptional circumstances is aimed at the provision of information on the safe and effective use of the product and will normally not lead to the completion of a full dossier/approval.

Market Authorizations Granted by Authorities of E.U. Member States

In general, if the centralized procedure is not followed, there are three alternative procedures as prescribed in Directive 2001/83/EC:

A marketing authorization may be granted only to an applicant established in the European Union.

Pediatric Studies

Prior to obtaining a marketing authorization in the European Union, applicants have to demonstrate compliance with all measures included in an EMA‑approved Pediatric Investigation Plan, or PIP, covering all subsets of the pediatric population, unless the EMA has granted a product‑specific waiver, a class waiver, or a deferral for one or more of the measures included in the PIP. The respective requirements for all marketing authorization procedures are set forth in Regulation (EC) No 1901/2006, which is referred to as the Pediatric Regulation. This requirement also applies when a company wants to add a new indication, pharmaceutical form or route of administration for a medicine that is already authorized. The Pediatric Committee of the EMA, or PDCO, may grant deferrals for some medicines, allowing a company to delay development of the medicine in children until there is enough information to demonstrate its effectiveness and safety in adults. The PDCO may also grant waivers when development of a medicine in children is not needed or is not appropriate, such as for diseases that only affect the elderly population.

Before a marketing authorization application can be filed, or an existing marketing authorization can be amended, the EMA determines that companies actually comply with the agreed studies and measures listed in each relevant PIP.

Periods of Authorization and Renewals

A marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the basis of a re‑evaluation of the risk‑benefit balance by the EMA or by the competent authority of the authorizing member state. To this end, the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months before the marketing authorization ceases to be valid. Once renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the competent authority decides, on justified grounds relating to pharmacovigilance, to proceed with one additional five‑year renewal. Any authorization which is not followed by the actual placing of the drug on the E.U. market (in case of centralized procedure) or on the market of the authorizing member state within three years after authorization ceases to be valid (the so‑called sunset clause).

Regulatory Data Protection

E.U. legislation also provides for a system of regulatory data and market exclusivity. According to Article 14(11) of Regulation (EC) No 726/2004, as amended, and Article 10(1) of Directive 2001/83/EC, as amended, upon receiving marketing authorization, new chemical entities approved on the basis of complete independent data package benefit from eight years of data exclusivity and an additional two years of market exclusivity. Data exclusivity prevents regulatory authorities in the E.U. from referencing the innovator’s data to assess a generic (abbreviated) application. During the additional two‑year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic medicinal product can be marketed until the expiration of the market exclusivity. The overall ten‑year period will be extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity and the innovator is able to gain the period of data exclusivity, another company nevertheless could also market another version of the drug if such company obtained marketing authorization based on an MAA with a complete independent data package of pharmaceutical test, preclinical tests and clinical trials. However, products designated as orphan medicinal products enjoy, upon receiving marketing authorization, a period of ten years of orphan market exclusivity. Depending upon the timing and duration of the E.U. marketing authorization process, products may be eligible for up to five years’ supplementary protection certificates, or SPCs, pursuant to Regulation (EC) No 469/2009. Such SPCs extend the rights under the basic patent for the drug.

Regulatory Requirements After a Marketing Authorization has been Obtained

If we obtain authorization for a medicinal product in the E.U., we will be required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of medicinal products:

Pharmacovigilance and other requirements

We will, for example, have to comply with the E.U.’s stringent pharmacovigilance or safety reporting rules, pursuant to which post‑authorization studies and additional monitoring obligations can be imposed. Other requirements relate, for example, to the manufacturing of products and APIs in accordance with good manufacturing practice standards. E.U. regulators may conduct inspections to verify our compliance with applicable requirements, and we will have to continue to expend time, money and effort to remain compliant. Non‑compliance with E.U. requirements regarding safety monitoring or pharmacovigilance, and with requirementsmatters related to the development and commercialization of productsthe Pascomer product, in which both the Company and AFT have the right to appoint two members. The committee is currently comprised of three members. We have final decision-making authority on all matters relating to the commercialization of the Pascomer product in the specified territory and on all matters related to the development (and regulatory approval) of the Pascomer product, with certain exceptions.

The development of the Pascomer product is being conducted pursuant to a written development plan, written by AFT and approved by the joint steering committee, which is reviewed on at least an annual basis. AFT shall perform clinical trials of the Pascomer product in the specified territory and shall perform all CMC (chemistry, manufacturing and controls) and related activities to support regulatory approval. We are responsible for all expenses incurred by AFT during the term of the AFT License Agreement and shall equally share all costs and expenses with AFT, incurred by AFT for development and marketing work performed in furtherance of regulatory approval and commercialization worldwide, outside of the specified territory. We are also entitled to receive a significant percentage of the economics (royalties and milestones) in any licensing transaction that AFT executes outside of North America, Australia, New Zealand, and Southeast Asia.

Upon closing of the AFT License Agreement, we were obligated to reimburse AFT for previously spent development costs, subject to certain limitations and were obligated to pay a one-time, irrevocable and non-creditable upfront payment to AFT, payable in scheduled installments. AFT is entitled to up to $25.5 million of cash milestone payments relating to certain regulatory and commercial achievements of the AFT License. In addition, AFT is entitled to net sales royalties ranging from high single digits to low double digits for the pediatric population, can also result in significant financial penalties in the E.U. Similarly, failure to comply with the E.U.’s requirements regarding the protection of individual personal data can also lead to significant penaltiesprogram licensed. The potential regulatory and sanctions. Individual E.U. member states may also impose various sanctionscommercial milestones are not yet considered probable, and penalties in case we do not comply with locally applicable requirements.

Manufacturing

The manufacturing of authorized drugs, for which a separate manufacturer’s license is mandatory, must be conducted in strict compliance with the EMA’s Good Manufacturing Practices, or GMP, requirements and comparable requirements of other regulatory bodies in the E.U., which mandate the methods, facilities and controls used in manufacturing, processing and packing of drugs to assure their safety and identity. The EMA enforces its current GMP requirements through mandatory registration of facilities and inspections of those facilities. The EMA mayno milestone payments have a coordinating role for these inspections while the responsibility for carrying them out rests with the member states competent authority under whose responsibility the manufacturer falls. Failure to comply with these requirements could interrupt supply and result in delays, unanticipated costs and lost revenues, and could subject the applicant to potential legal or regulatory action, including but not limited to warning letters, suspension of manufacturing, seizure of product, injunctive action or possible civil and criminal penalties.

Marketing and Promotion

The marketing and promotion of authorized drugs, including industry‑sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or the general public, are strictly regulated in the European Union under Directive 2001/83/EC. The applicable regulations aim to ensure that information provided by holders of marketing authorizations regarding their products is truthful, balanced and accurately reflects the safety and efficacy claims authorized by the EMA or by the competent authority of the authorizing member state. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties.

Patent Term Extension

In order to compensate the patentee for delays in obtaining a marketing authorization for a patented product, a supplementary certificate, or SPC, may be granted extending the exclusivity period for that specific product by up to five years. Applications for SPCs must be made to the relevant patent office in each E.U. member state and the granted certificates are valid only in the member state of grant. An application has to be made by the patent owner within six months of the first marketing authorization being granted in the European Union (assuming the patent in question has not expired, lapsed or been revoked) or within six months of the grant of the patent (if the marketing authorization is granted first). In the context of SPCs, the term “product” means the active ingredient or combination of active ingredients for a medicinal product and the term “patent” means a patent protecting such a product or a new manufacturing process or application for it. The duration of an SPC is calculated as the difference between the patent’s filing date and the date of the first marketing authorization, minus five years, subject to a maximum term of five years.

A six month pediatric extension of an SPC may be obtained where the patentee has carried out an agreed pediatric investigation plan, the authorized product information includes information on the results of the studies and the product is authorized in all member states of the European Union.

Brexit and the Regulatory Framework in the United Kingdomaccrued at December 31, 2020.

On June 23, 2016, the electorate in the United Kingdom, or U.K. voted in favorCompetition

We are aware of leaving the E.U.several companies that are working to develop drugs that would compete against our product candidates, such as Mayne Pharma Group Limited, which is developing trifarotene for lamellar ichthyosis, Krystal Biotech, Inc., which is commonly referred to as “Brexit.” Thereafter, on March 29, 2017, the country formally notified the E. U. of its intention to withdraw pursuant to Article 50 of the Lisbon Treaty. The withdrawal of the U.K. from the E.U. will take effect eitherdeveloping KB105 for transglutaminase-1 deficient autosomal recessive congenital ichthyosis, and Nobelpharma Co., Ltd. and Aucta Pharmaceuticals, Inc., which are developing topical rapamycin for facial angiofibromas in tuberous sclerosis complex.

on the effective date of the withdrawal agreement or, in the absence of agreement, two years after the U.K. provides a notice of withdrawal pursuant to the E.U. Treaty. Since the regulatory framework for pharmaceutical products in the U.K. covering quality, safety and efficacy of pharmaceutical products, clinical trials, marketing authorization, commercial sales and distribution of pharmaceutical products is derived from E.U. directives and regulations, Brexit could materially impact the future regulatory regime which applies to products and the approval of product candidates in the U.K. It remains to be seen how, if at all, Brexit will impact regulatory requirements for product candidates and products in the U.K.Employees

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Sales of products will depend, in part, on the extent to which the costs of the products will be covered by third‑party payors, including government health programs in the United States such as Medicare and Medicaid, commercial health insurers and managed care organizations. The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third‑party payors may limit coverage to specific products on an approved list, or formulary, which might not include all of the approved products for a particular indication.

In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost‑effectiveness of the product, in addition to the costs required to obtain FDA or other comparable regulatory approvals. A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Third‑party reimbursement may not be sufficient to maintain price levels high enough to realize an appropriate return on investment in product development.

In the E.U., pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost‑effectiveness of our drug candidate to currently available therapies (so called health technology assessment) in order to obtain reimbursement or pricing approval. For example, the E.U. provides options for its member states to restrict the range of drug products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. E.U. member states may approve a specific price for a drug product or it may instead adopt a system of direct or indirect controls on the profitability of the Company placing the drug product on the market. Other member states allow companies to fix their own prices for drug products, but monitor and control prescription volumes and issue guidance to physicians to limit prescriptions. The downward pressure on health care costs in general, particularly prescription drugs, has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various E.U. member states, and parallel distribution (arbitrage between low‑priced and high‑priced member states), can further reduce prices. Any country that has price controls or reimbursement limitations for drug products may not allow favorable reimbursement and pricing arrangements.

Healthcare Law and Regulation

Healthcare providers, physicians and third‑party payors play a primary role in the recommendation and prescription of drug products that are granted marketing approval. Arrangements with third‑party payors and customers are subject to broadly applicable fraud and abuse and other healthcare laws and regulations. Such restrictions under applicable federal and state healthcare laws and regulations, include the following:

An increasing number of states have enacted legislation requiring pharmaceutical and biotechnology companies to file periodic reports of expenses relating to the marketing and promotion of drug products and gifts and payments to individual healthcare practitioners in these states; to make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities; to report information pertaining to and justifying price increases; or to register their sales representatives.  Other states prohibit various marketing-related activities, such as the provision of certain kinds of gifts or meals; price gouging; or pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing. In addition, states such as California, Connecticut, Nevada, and Massachusetts require pharmaceutical companies to implement compliance programs and/or marketing codes. State and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Environmental, Health and Safety Matters

The manufacturing facilities of the third‑parties that develop our product candidates are subject to extensive environmental, health and safety laws and regulations in a number of jurisdictions, governing, among other things: the use, storage, registration, handling, emission and disposal of chemicals, waste materials and sewage; chemicals, air, water and ground contamination; air emissions and the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals, waste materials and sewage.

These laws, regulations and permits could potentially require the expenditure by us of significant amounts for compliance or remediation. If the third‑party manufacturers fail to comply with such laws, regulations or permits, we may be subject to fines and other civil, administrative or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. In addition, we may be required to pay damages or civil judgments in respect of third‑party claims, including those relating to personal injury (including exposure to hazardous substances we use, store, handle, transport, manufacture or dispose of), property damage or contribution claims. Some environmental, health and safety laws allow for strict, joint and several liability for remediation costs, regardless of comparative fault. We may be identified as a responsible party under such laws. Such developments could have a material adverse effect on our business, financial condition and results of operations.

In addition, laws and regulations relating to environmental, health and safety matters are often subject to change. In the event of any changes or new laws or regulations, we could be subject to new compliance measures or to penalties for activities that were previously permitted.

Employees

As of JanuaryDecember 31, 2018,2020, we had 27 employees, all of whom were full time, including 13 employees in research and development and one employee located outside of the United States. We also retain independent contractors to support our organization.six full-time employees. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We have not experienced any work stoppagesagreement, and we consider our employee relations with our employees to be good.satisfactory. Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and new employees, advisors and consultants with the overall goal of having an employee base that embraces teamwork and shares a focus for using each person’s individual skills, experience and expertise in order to develop and maximize the value of corporate assets, and achieve long-term revenue and earnings growth.

Other Information

We are subject to the information requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Therefore, we file periodic reports, proxy statements and other information with the SEC. Such reports, proxy statements and other information may be obtained, free of charge, by visiting the Public Reference RoomSEC’s website at www.sec.gov that contains all of the SEC at 100 F Street, NE, Washington, D.C. 20549 or by calling the SEC at 1‑800‑SEC‑0330, by sending an electronic message to the SEC at publicinfo@sec.gov or by sending a fax to the SEC at 1‑202‑777‑1027.

Pharmaceutical product development is a highly speculative and costly undertaking and involves a substantial degreesince inception, we have incurred significant net losses. As of uncertainty. We have never been profitable and, as of JanuaryDecember 31, 2018,2020, we had an accumulated deficit of $61.3approximately $18.2 million. Since inception, we have financed our operations with $18.9 million through capital contributions.

Our ability to generate product revenue and incurredbecome profitable depends upon our ability to successfully complete the development of, and obtain the necessary regulatory approvals for, our product candidates in development, including TMB-001, TMB-002 and TMB-003. We have never been profitable, have no products approved for commercial sale, and have not generated any product revenue.

Even if we receive regulatory approval for any of our product candidates, we do not know when or if such product candidate will generate product revenue. Our ability to generate product revenue depends on a number of factors, including, but not limited to, our ability to:

Because of the numerous risks and uncertainties associated with product development, Timber is unable to predict the timing or amount of increased expenses, or when or if, we will be able to achieve or maintain profitability. Our expenses could increase beyond expectations if we are required by the FDA or comparable non-U.S. regulatory authorities to perform studies or clinical trials in addition to those that we currently anticipate. Even if any of our product candidates are approved for commercial sale, we anticipate incurring significant costs associated with their commercial launch. If we cannot successfully execute any one of the foregoing, our business may not succeed and your investment will be negatively impacted.

We expect to incur significant losses for the foreseeable future and may never achieve or maintain profitability. Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern.

Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a product candidate will fail to gain regulatory approval or fail to become commercially viable. We have never generated any product revenue, and we cannot estimate with precision the extent of its future losses. We do not currently have any products that are available for commercial sale and we may never generate product revenue or achieve profitability.

As of December 31, 2020, we had an accumulated deficit of approximately $18.2 million.

We expect to continue to incur netsubstantial and increasing losses forthrough the foreseeable future as we advance our current and potential additional product candidates through clinical development, seek regulatory approval for them and prepare for and proceed to commercialization. Becausecommercialization of the risks and uncertainties associated with developing and commercializingany of our product candidates, if approved. None of our product candidates have been approved for marketing anywhere in the world, and we may never receive such approval. As a result, we are unableuncertain when or if we will achieve profitability and, if so, whether we will be able to predict whensustain it. Our ability to generate product revenue and achieve profitability is dependent on our ability to complete the development of our product candidates, obtain necessary regulatory approvals for such product candidates, and manufacture and successfully market our product candidates alone or in collaboration with others. There can be no assurance that we will be profitable even if we successfully commercialize any of our product candidates. If we do successfully obtain regulatory approval to market any of our product candidates, our revenue will be dependent upon, in part and among other things, the size of the markets in the territories for which it gains regulatory approval, the number of competitors in such markets, the accepted price for any such product candidate and whether we own the commercial rights for those territories. If the indication approved by regulatory authorities is narrower than we expect, or the treatment population is narrowed by competition, physician choice or treatment guidelines, we may introduce additional products commercially, the extentnot generate significant revenue from sales of any future losses or when we will become profitable,of our product candidates, even if at all.approved. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Failure to become and remain profitable may adversely impact the market price of our common stock and our ability to raise capital and continue operations.

We expect that our research and development expenses in connection with our development programs for our various product candidates will needcontinue to be significant. In addition, as we prepare for and if we obtain regulatory approval for any of our product candidates, we expect to incur increased sales, marketing and manufacturing expenses. As a result, we expect to continue to incur significant and increasing operating losses and negative cash flows for the foreseeable future. These losses have harmed and will continue to harm our results of operations, financial position and working capital.

Our independent registered public accounting firm has issued a going concern opinion on our consolidated financial statements as of December 31, 2020, expressing substantial doubt that we can continue as an ongoing business due to insufficient capital for us to fund our operations.

Our business is heavily dependent on the successful development, regulatory approval and commercialization of our product candidates.

We currently have no products that are approved for commercial sale and may never be able to develop marketable products. We expect that a substantial portion of its efforts and expenditures will be devoted to the continued clinical evaluation of our lead product candidates TMB-001, TMB-002 and TMB-003 and the commercialization of such product candidates following regulatory approval, if received, as well as the continued clinical and preclinical evaluation of any of its other product candidates. Accordingly, our business currently depends heavily on the successful completion of its clinical trials for our product candidates and subsequent regulatory approval and commercialization of such product candidates.

We cannot be certain that any of our product candidates will receive regulatory approval or be successfully commercialized even if such product candidates receive regulatory approval. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of products are, and will remain, subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries that each have differing regulations. We are not permitted to market any of our product candidates in the United States until we receive approval of an NDA or in any foreign country until we receive the requisite approvals from the appropriate authorities in such countries for marketing authorization. In addition, we have not yet demonstrated our ability to complete later-stage or pivotal clinical trials for any of our product candidates.

We have not submitted an NDA for any of our product candidates to the FDA or any comparable application to any other regulatory authority. Obtaining approval of an NDA or similar regulatory approval is an extensive, lengthy, expensive and inherently uncertain process, and the FDA or other foreign regulatory authorities may delay, limit or deny approval of any of our product candidates for many reasons, including:

Even if we do receive regulatory approval to market any product candidate, any such approval may be subject to limitations on the indicated uses or patient populations for which we may market the product. Accordingly, even if we are able to obtain the requisite financing to continue to fund our development programs, we cannot assure you that any of our product candidates will be successfully developed or commercialized.

In addition, because each of our product candidates targets one or more indications in the medical dermatology field, if any of our product candidates encounter safety or efficacy problems, developmental delays, regulatory issues, supply issues, or other problems, our development plans for the affected product candidate and some or all of our other product candidates could be significantly harmed, which would harm our business. Further, competitors who are developing products in the dermatology field or that target the same indications as us with products that have a similar mechanism of action may experience problems with its products that could identify problems that would potentially harm our business.

Outbreaks of communicable diseases, including the COVID-19, may materially and adversely affect our business, financial condition and results of operations.

We face risks related to health epidemics or outbreaks of communicable diseases, for example, the recent outbreak around the world, of the highly transmissible and pathogenic COVID-19. The outbreak of such communicable diseases could result in a widespread health crisis that could adversely affect general commercial activity and the economies and financial markets of many countries.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China and on March 11, 2020, was declared a pandemic by the World Health Organization. The ultimate impact of the COVID-19 pandemic on our operations is unknown and will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the COVID-19 outbreak, new information which may emerge concerning the severity of the COVID-19 pandemic, and any additional preventative and protective actions that governments, or we, may determine are needed.

To date, many countries around the world have imposed quarantines and restrictions on travel and mass gatherings to slow the spread of COVID-19 and have closed non-essential businesses. As local jurisdictions continue to put restrictions in place, our ability to continue to operate our business may also be limited. Such events may result in a period of business, supply and drug product manufacturing disruption, and in reduced operations, any of which could materially affect our business, financial condition and results of operations. It is also possible that COVID-19 could disproportionately impact the hospitals and clinical sites in which we conduct any of our clinical trials, which could have a material adverse effect on our business and our results of operation and financial condition.

The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock.

This pandemic could result in difficulty securing clinical trial site locations, CROs, and/or trial monitors and other critical vendors and consultants supporting the trial. In addition, outbreaks or the perception of an outbreak near a clinical trial site location could impact the Company’s ability to enroll patients. These situations, or others associated with COVID-19, could cause delays in the Company’s clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company’s business and its financial condition.

The COVID-19 outbreak may also affect the ability of our staff and the parties we work with to carry out our non-clinical, clinical, and drug manufacturing activities. We rely or may in the future rely on clinical sites, investigators and other study staff, consultants, independent contractors, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our nonclinical studies and clinical trials. We also rely or may in the future rely on consultants, independent contractors, contract manufacturing organizations, and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our active pharmaceutical ingredient production, formulation, and drug manufacturing activities. COVID-19 may affect the ability of any of these external people, organizations, or companies to devote sufficient time and resources to our programs or to travel to perform work for us.

Potential negative impacts of the COVID-19 outbreak on the conduct of current or future clinical studies include delays in gaining feedback from regulatory agencies, starting new clinical studies, and recruiting subjects to studies that are enrolling. The potential negative impacts also include inability to have study visits at study sites, incomplete collection of safety and efficacy data, and higher rates of drop-out of subjects from ongoing studies, delays in site entry of study data into the data base, delays in monitoring of study data because of restricted physical access to study sites, delays in site responses to queries, delays in data-base lock, delays in data analyses, delays in time to top-line data, and delays in completing study reports. New or worsening COVID-19 disruptions or restrictions could have the potential to further negatively impact our non-clinical studies, clinical trials, and drug manufacturing activities.

We will require substantial additional funding. Ifcapital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization of any of our product candidates.

We expect to spend substantial capital to complete the development of, seek regulatory approvals for and commercialize our lead product candidates, TMB-001, TMB-002 and TMB-003, as well as any of our other product candidates. We will require additional capital to complete the development and potential commercialization of our product candidates. Because the length of time and activities associated with successful development of our product candidates are highly uncertain, we are unable to raise capital when needed, we may need to significantly delay, scale back or discontinueestimate with certainty the development or commercialization of one or more of our product candidates.

We incurred a net loss available to common stockholders of $16.6 million and $18.5 million for the years ended January 31, 2018 and 2017, respectively. As of January 31, 2018, we had cash and cash equivalents of $7.6 million and significant liabilities and obligations. In April 2017, we raised net proceeds of $4.4 million through the sale of common stock and warrants to purchase common stock through a registered direct offering. In July 2017, we raised net proceeds of $1.9 million through the sale of common stock through an additional registered direct offering.  In November 2017, we raised net proceeds of $9.7 million through the sale of common stock and warrants to purchase common stock in a public offering. We presented comprehensive BPX01 Phase 2b clinical data for the treatment of acne and received positive FDA feedback regarding our BPX01 Phase 3 clinical study plans. We will seek to enter into a strategic partnership to fund the continued clinical development of BPX01 for the treatment of inflammatory lesions of acne, and there is no assuranceactual funds we will be successful in entering into such strategic partnership in a timely manner or on acceptable terms. If we are unable to enter into a strategic partnership to fund the continued development of BPX01, we may be unable to complete clinical development of BPX01. We recently initiated a pre-Phase 2 feasibility study to assess the safety and efficacy of BPX04require for the treatment of rosacea. Our existing resources may not be adequate to permit us to complete clinical development of BPX04 or to fund our operations over the longer term. We will need to secure

significant additional resources to complete such development and to support our continued operationsany approved marketing and are exploring a variety ofcommercialization activities. Our future funding alternatives,requirements, both near-and long-term, will depend on many factors, including, both dilutive and non-dilutive financing options and strategic partnerships. Absent additional funding, webut not limited to:

We believe that our existing cash will be sufficient to fund our operations only for a relatively short periodoperating expenses and capital expenditure requirements into at least the third quarter of time.

The development ofcalendar year 2021. This estimate is based on assumptions that may prove to be wrong, and we could use our business will require substantialavailable capital resources sooner than we currently expect. We cannot be certain that additional capital in the future to conduct research and develop our other product candidates, as well as to fund our ongoing operations and satisfy our obligations and liabilities. We have historically relied upon both private and public sales of equity or debt securities to fund our operations. Our clinical studies for our product candidates may not be successful or may not generate results that are compelling enough to support future funding or strategic partnerships. Delays in obtaining funding could adversely affect our ability to develop and commercially introduce products and cause us to be unable to comply with our obligations. Our ability to obtain additional financing will be subject to a number of factors, including market conditions, our operating performance and investor sentiment.available on acceptable terms, or at all. If we are unable to raise additional capital when requiredin sufficient amounts or on terms acceptable terms,to us, we may have to significantly delay, scale back or discontinue the development or commercialization of any product candidate, or potentially discontinue operations altogether. In addition, attempting to secure additional capital may divert the time and attention of our management from day-to-day activities and harm our product candidate development efforts. Because of the numerous risks and uncertainties associated with the development and potential commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays, operating expenditures and capital requirements associated with our current product development programs.

Raising additional funds by issuing equity securities may cause dilution to existing equity holders, raising additional funds through debt financings may involve restrictive covenants, and raising funds through lending and licensing arrangements may restrict our operations or require us to relinquish proprietary rights.

We expect that significant additional capital will be needed in the future to continue our planned operations. Until such time, if ever, that we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic alliances and license and development agreements or other collaborations. To the extent that we raise additional capital by issuing equity securities, existing equity ownership may experience substantial dilution, and the securities may include preferred shares with liquidation or other preferences that could harm the rights of our securityholders.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise develop and market ourselves.

Issuance of our common stock upon exercise of convertible securities may depress the price of our common stock.

As of March 15, 2021, we had 36,843,045 shares of common stock issued and outstanding, outstanding, warrants to purchase 17,335,503 shares of common stock at a weighted exercise price of $2.37 and outstanding stock options to purchase 200,237 shares of common stock at a weighted exercise price of $8.58 per share. In addition, we have outstanding value appreciation rights convertible into an aggregate of 367,670 shares of common stock.  All warrants and stock options are convertible, or exercisable into, one share of common stock. The issuance of shares of our common stock upon the exercise of outstanding convertible securities could result in substantial dilution to our stockholders, which may have a negative effect on the price of our common stock.

The Company has a class of Series A Preferred Stock which is currently redeemable, subject to Delaware law.

The Company has a class of Series A Preferred Stock which is currently subject to redemption at any time in whole or in part at the request of the holder, TardiMed.  The redemption price is equal to approximately $1.9 million in the aggregate, including accumulated and unpaid dividends which accrue dividends at the rate of 8% per annum.  Redemption is subject to certain limitations under Delaware law, so that our ability to pay the redemption price to TardiMed may be limited. 

Our stock price can be volatile, which increases the risk of litigation, and may result in a significant decline in the value of your investment.

Since the completion of the Merger on May 18, 2020, the market price of our common stock has varied between a high of $5.69 and a low of $0.665. The trading price of our common stock has historically been, and is likely to continue to be, highly volatile and subject to wide fluctuations in price in response to various factors, many of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose part or all of your investment in our common stock. These factors include, but are not limited to, the following:

These broad market and industry factors may materially affect the market price of our common stock, regardless of our development and operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. Due to the volatility of our stock price, we are currently and may be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention in the future attention and resources from our business.

If we are unable to effectively maintain a system of internal control over financial reporting, we may not be able to accurately or timely report our financial results and our stock price could be adversely affected.

We maintain disclosure controls and procedures designed to ensure that we timely report information as specified in the rules and regulations of the SEC. We also maintain a system of internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of the financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Effective internal control over financial reporting is necessary for us to provide reliable reports and prevent fraud. Any failure to address such difficulties encountered in maintaining operation of these internal controls over financial reporting, could harm our operations, decrease the reliability of our financial reporting, and cause us to fail to meet our financial reporting obligations, which could adversely affect our business and reduce our stock price.

We are subject to extensive and costly government regulation.

Product candidates employing our technology are subject to extensive and rigorous domestic government regulation including regulation by the FDA, the Centers for Medicare and Medicaid Services, other divisions of the United States Department of Health and Human Services, the United States Department of Justice, state and local governments, and their respective foreign equivalents. The FDA regulates the research, development, preclinical and nonclinical testing and clinical studies, manufacture, safety, effectiveness, record-keeping, reporting, labeling, storage, approval, advertising, promotion, sale, distribution, import, and export of biopharmaceutical products. The FDA regulates small molecule chemical entities as drugs, subject to an NDA under the Federal Food, Drug, and Cosmetic Act (“FDCA”). The FDA applies the same standards for biologics, requiring an investigational new drug ("IND") application, followed by a Biologic License Application, or BLA, prior to licensure. Other products, such as vaccines, are also regulated under the Public Health Service Act. The FDA has conflated the standards for approval of NDAs and BLAs so that it requires the same types of information on safety, effectiveness, and CMCs. If products employing our technologies are marketed abroad, they will also be subject to extensive regulation by foreign governments, whether or not they have obtained FDA approval for a given product and its uses. Such foreign regulation may be equally or more demanding than corresponding United States regulation.

Government regulation substantially increases the cost and risk of researching, developing, manufacturing, and selling our products. The regulatory review and approval process, which includes preclinical and nonclinical testing and clinical studies of each product candidate, is lengthy, expensive, and uncertain. We or our collaborators must obtain and maintain regulatory authorization to conduct clinical studies. We or our collaborators must obtain regulatory approval for each product we intend to market, and the manufacturing facilities used for the products must be inspected and meet legal requirements. Securing regulatory approval requires the submission of extensive preclinical, nonclinical and clinical data and other supporting information for each proposed therapeutic indication in order to establish the product's safety and efficacy, and in the case of biologics also potency and purity, for each intended use. The development and approval process takes many years, requires substantial resources, and may never lead to the approval of a product.

Even if we are able to obtain regulatory approval for a particular product, the approval may limit the indicated medical uses for the product, may otherwise limit our ability to promote, sell, and distribute the product, may require that we conduct costly post-marketing surveillance, and/or may require that we conduct ongoing post-marketing studies. Material changes to an approved product, such as, for example, manufacturing changes or revised labeling, may require further regulatory review and approval. Once obtained, any approvals may be withdrawn, including, for example, if there is a later discovery of previously unknown problems with the product, such as a previously unknown safety issue.

If we, ours collaborators, or our contract manufacturing organizations ("CMOs") fail to comply with applicable regulatory requirements at any stage during the regulatory process, such noncompliance could result in, among other things delays in the approval of applications or supplements to approved applications; refusal of a regulatory authority, including the FDA, to review pending market approval applications or supplements to approved applications; warning letters; fines; import and/or export restrictions; product recalls or seizures; injunctions; total or partial suspension of production; civil penalties; withdrawals of previously approved marketing applications or licenses; recommendations by the FDA or other regulatory authorities against governmental contracts; and/or criminal prosecutions.

We do not have, and may never obtain, the regulatory approvals we need to market our product candidates.

Following completion of clinical studies, the results are evaluated and, depending on the outcome, submitted to the FDA in the form of an NDA or BLA in order to obtain FDA approval of the product and authorization to commence commercial marketing. In responding to an NDA, the FDA may require additional testing or information, may require that the product labeling be modified, may impose post-approval study and other commitments or reporting requirements or other restrictions on product distribution, or may deny the application. The FDA has established performance goals for review of NDAs or BLAs: six months for priority applications and ten months for standard applications. However, the FDA is not required to complete its review within these time periods. The timing of final FDA review and action varies greatly but can take years in some cases and may involve the input of an FDA advisory committee of outside experts. Product sales in the United States may commence only when an NDA or BLA is approved.

It is possible that none of our product candidates will be approved for marketing. Failure to obtain regulatory approvals, or delays in obtaining regulatory approvals, may adversely affect the successful commercialization of any drugs or biologics that we or our partners develop, may impose additional costs on us or our collaborators, may diminish any competitive advantages that we or our partners may attain, and/or may adversely affect our receipt of revenues or royalties.

If we are unable to file for approval of TMB-001 or TMB-002 under Section 505(b)(2) of the FDCA or if we are required to generate additional data related to safety and efficacy in order to obtain approval under Section 505(b)(2), we may be unable to meet our anticipated development and commercialization timelines.

Our current plans for filing NDAs for our product candidates include efforts to minimize the data we will be required to generate in order to obtain marketing approval for its product candidates and therefore reduce the development time. We have held pre-IND meetings with the FDA to discuss, among other things, the regulatory pathways for TMB-001 and TMB-002. The timelines for filing and review of our NDAs for TMB-001 and TMB-002 are based on its plan to submit such NDAs under Section 505(b)(2) of the FDCA, which would enable us to rely in part on data in the public domain or elsewhere. We have not yet filed an NDA under Section 505(b)(2) for any of our product candidates. Depending on the data that may be required by the FDA for approval, some of the data may be related to products already approved by the FDA. If the data relied upon is related to products already approved by the FDA and covered by third-party patents, we would be required to certify that we do not infringe the listed patents or that such patents are invalid or unenforceable. As a result of the certification, the third-party would have 45 days from notification of our certification to initiate an action against us.

In the event that an action is brought in response to such a certification, the approval of our NDA could be subject to a stay of up to 30 months or more while we defend against such a suit. Approval of our product candidates under Section 505(b)(2) may therefore be delayed until patent exclusivity expires or until we successfully challenge the applicability of those patents to such product candidates. Alternatively, we may elect to generate sufficient additional clinical data so that we no longer rely on data which triggers a potential stay of the approval of our product candidates. Even if no exclusivity periods apply to our applications under Section 505(b)(2), the FDA has broad discretion to require us to generate additional data on the safety and efficacy of our product candidates to supplement third-party data on which we may be permitted to rely. In either event, we could be required, before obtaining marketing approval for any of our product candidates, to conduct substantial new research and development activities beyond those we currently plan to engage in order to obtain approval of our product candidates. Such additional new research and development activities would be costly and time consuming.

We may not be able to realize a shortened development timeline for our product candidates, and the FDA may not approve an NDA based on our review of the submitted data. If products containing isotretinoin or rapamycin are withdrawn from the market by the FDA for any safety reason, we may not be able to reference such products to support a 505(b)(2) NDA for TMB-001 or TMB-002, respectively, and we may need to fulfill the more extensive requirements of Section 505(b)(1). If we are required to generate additional data to support approval, we may be unable to meet our anticipated development and commercialization timelines, may be unable to generate the additional data at a reasonable cost, or at all, and may be unable to obtain marketing approval of our lead product candidates.

Even if we are able to commercialize any product candidate that we may develop, the product may become subject to unfavorable pricing regulations, third-party payor reimbursement practices or healthcare reform initiatives that could harm our business.

The commercial success of our current or future product candidates will depend substantially, both domestically and abroad, on the extent to which the costs of its product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities (such as Medicare and Medicaid), private health coverage insurers and other third-party payors. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize its products. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish and maintain pricing sufficient to realize a meaningful return on its investment.

There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved drugs. Marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some non-U.S. markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch of the product, possibly for lengthy time periods, which may negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup its investment in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize our product candidates will depend in part on the extent to which coverage and reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will cover and establish reimbursement levels. The healthcare industry is acutely focused on cost containment, both in the United States and elsewhere. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications, which could affect our ability to sell our product candidates profitably. These payors may not view our products, if any, as cost-effective, and coverage and reimbursement may not be available to our customers, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost-control initiatives could cause us to decrease the price we might establish for products, which could result in lower than anticipated product revenues. If the prices for our products, if any, decrease or if governmental and other third-party payors do not provide adequate coverage or reimbursement, our prospects for revenue and profitability will suffer.

There may also be delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the indications for which the drug is approved by the FDA or comparable non-U.S. regulatory authorities. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Reimbursement rates may vary, by way of example, according to the use of the drug and the clinical setting in which it is used. Reimbursement rates may also be based on reimbursement levels already set for lower cost drugs or may be incorporated into existing payments for other services.

In addition, increasingly, third-party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and are challenging the prices charged. We cannot be sure that coverage will be available for any product candidate that we may commercialize and, if available, that the reimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. An inability to promptly obtain coverage and adequate payment rates from both government-funded and private payors for any of our product candidates for which we obtain marketing approval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

We rely on our license agreement and acquisition agreements to provide rights to certain intellectual property relating to certain of our product candidates. Any termination or loss of significant rights under any such agreements would adversely impact our development or commercialization of such product candidates.

We have licensed certain intellectual property relating to certain of its product candidates from AFT Pharmaceuticals Limited, or AFT, through a license agreement. We have acquired the rights to certain intellectual property relating to certain of its product candidates from Patagonia through two acquisition agreements. If, for any reason, our license agreement or acquisition agreements are terminated or we otherwise lose those rights, it would harm our business. Our license agreement imposes on us obligations relating to exclusivity, territorial rights, development, commercialization, funding, payment, diligence, sublicensing, insurance, intellectual property protection and other matters. Our acquisition agreements impose on us obligations and restrictions relating to development, commercialization, funding, sublicensing, non-competition, intellectual property protection, payment and royalties and other matters. If we breach any material obligations, or use the intellectual property licensed to or acquired by us in an unauthorized manner, we may be required to pay damages to our collaborators and such collaborators may have the right to terminate the applicable licenses or rights, as applicable, which would result in us being unable to develop, manufacture and sell one or more of our product candidates, restrict our operations or obtain funds by entering into agreements on unattractive terms, which would likely have a material adverse effect on our business, stock priceif approved. In addition, under the license agreement, the licensor has the first right to file, prosecute (including any post-grant proceeding) and our relationships with third parties with whommaintain all licensed patents, and we have business relationships, at least until additional funding is obtained. If we domay not have sufficient fundsany control over such actions unless such licensor elects not to continue operations,exercise our rights.

Our license agreement and acquisition agreements with AFT and Patagonia obligate us to make certain milestone payments.

We are obligated to pay certain milestone payments to AFT and Patagonia pursuant to their license agreement and acquisition agreements. Zachary Rome, our Executive Vice-President and Chief Operating Officer serves as President of Patagonia and also maintains an ownership interest therein. AFT is entitled to up to $25.5 million of cash milestone payments relating to certain regulatory and commercial achievements of TMB-002. Patagonia is entitled to up to $27.0 million of cash milestone payments relating to certain regulatory and commercial achievements of TMB-001, with the first being initiation of a Phase 3 pivotal trial, as agreed with the FDA. Patagonia is also entitled to up to $10.25 million of cash milestone payments relating to certain regulatory and commercial achievements of TMB-003, with the first being a one-time payment of $250,000 upon the opening of an IND with the FDA.

Because certain of the milestone payments payable by us to AFT and Patagonia are due upon certain events related to the development and regulatory approval of its product candidates, we couldmay be required to seek bankruptcy protectionmake such payments prior to the time at which it is able to generate revenue, if any, from sales any of our product candidates, if approved. There can be no assurance that we will have the funds necessary to make such payments, or other alternativesbe able to raise such funds when needed, on terms acceptable to us, or at all. Furthermore, if we are forced to raise additional funds, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts, or grant rights to develop and market product candidates that we would likely result in our stockholders losing some or all of their investment in us.

Future discoveryotherwise develop and preclinical development collaborations are important to us.market ourselves. If we are unable to enter intoraise additional funds or maintain these collaborations,sufficient liquidity to make our payment obligations if and when they become due, we may be in material breach of our license and acquisition agreements and our counterparties may seek legal action or if these collaborationsremedies against us, which would harm our business, financial condition, results of operations and prospects.

If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business couldstrategy.

Our ability to compete in the highly competitive pharmaceuticals industry depends in large part upon our ability to attract highly qualified managerial, scientific and medical personnel. In order to induce valuable employees to remain with us, we intend to provide employees with stock options that vest over time. The value to employees of stock options that vest over time will be significantly affected by movements in the price of the common stock that we will not be able to control and may at any time be insufficient to counteract more lucrative offers from other companies.

Our management team has expertise in many different aspects of drug development and commercialization. However, we will need to hire additional personnel as we further develop our drug candidates. Competition for skilled personnel in the pharmaceutical industry is intense and competition for experienced scientists may limit our ability to hire and retain highly qualified personnel on acceptable terms. Despite our efforts to retain valuable employees, members of its management, scientific and medical teams may terminate their employment with us on short notice. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level, and senior managers as well as junior, mid-level, and senior scientific and medical personnel.

Other pharmaceutical companies with which we compete for qualified personnel have greater financial and other resources, different risk profiles, and a longer history in the industry than we do. Other pharmaceutical companies also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel, the rate and success at which we can develop and commercialize product candidates would be limited.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of December 31, 2020, we had six employees. As our development and commercialization plans and strategies develop, we will need to expand the size of our employee base for managerial, operational, sales, marketing, financial and other resources. Future growth would impose significant added responsibilities on members of management, including the need to identify, recruit, maintain, motivate and integrate additional employees. In addition, our management may have to divert a disproportionate amount of its attention away from its day-to-day activities, including the additional requirements on management as a public company, and devote a substantial amount of time to managing these growth activities. Our future financial performance, ability to commercialize our product candidates and our ability to compete effectively will depend, in part, on our ability to effectively manage our future growth.

We may not be successful in our efforts to identify and acquire or in-license additional product candidates, or to enter into collaborations or strategic alliances for the development and commercialization of any such future product candidates.

We may seek to identify and acquire or in-license novel product candidates in the medical dermatology field. The process by which we identify product candidates may fail to yield product candidates for clinical development for a number of reasons, including those discussed in these risk factors and also:

We may choose to focus our efforts and resources on a potential product candidate that ultimately proves to be unsuccessful. We also cannot be certain that, following an acquisition or in-licensing transaction, we will achieve the revenue or specific net income that justifies such transaction. Further, time and resources spent identifying, acquiring and developing potential product candidates may distract management's attention from Timber's primary business or other development programs. If we are unable to identify and acquire suitable product candidates for clinical development, this would adversely affected.impact our business strategy, our financial position and share price.

For some

In the future, may decide to collaborate with other pharmaceutical companies for the development and potential commercialization of our product candidates we may in the future determine to collaborate with pharmaceutical and biotechnology companies for developmentUnited States or other countries or territories of products. In particular, a part of our strategy is to seek to enter into enter into a strategic collaboration to fund the continued development of BPX01.world. We will face significant competition in seeking appropriate collaborators. We may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our product candidates because such product candidates may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy. If and when we collaborate with a third party for development and commercialization of a product candidate, it can expect to relinquish some or all of the control over the future success of that product candidate to the third party. Our ability to reach a definitive agreement for anya collaboration will depend, among other things, upon our assessment of the collaborator's resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator's evaluation of a number of factors. We may

International expansion of our business exposes us to business, legal, regulatory, political, operational, financial and economic risks associated with conducting business outside of the United States.

Part of our business strategy involves potential expansion internationally with third-party collaborators to seek regulatory approval for its product candidates outside the United States. Doing business internationally involves a number of risks, including but not succeedlimited to:

Any of these risks, if encountered, could significantly harm our future international expansion and operations and, consequently, negatively impact our financial condition, results of operations and cash flows.

Our business and operations would suffer in the event of system failures, cyber-attacks or a deficiency in our efforts to establish a development collaboration or other alternative arrangements for BPX01 becausecyber-security.

Our computer systems, as well as those of various third parties on which we rely, may not view BPX01sustain damage from computer viruses, unauthorized access, data breaches, phishing attacks, cybercriminals, natural disasters (including hurricanes and earthquakes), terrorism, war and telecommunication and electrical failures. We rely on our third-party providers to implement effective security measures and identify and correct for any such failures, deficiencies or breaches. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally increased as having the requisitenumber, intensity and sophistication of attempted attacks and intrusions from around the world have increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs. For example, the loss of nonclinical or clinical trial data from completed, ongoing or planned trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and the further development of any product candidate could be delayed.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of its drug candidates.

We face a potential risk of product liability as a result of the clinical testing of our drug candidates and will face an even greater risk if we commercialize our drug candidates. For example, we may be sued if any product we develop or any materials that we use in our products allegedly causes injury or is found to demonstrate safety,be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and efficacy or profitability.a breach of warranties. Claims could also be asserted under state consumer protection acts. If we are unablecannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to reach agreements with suitable collaborators onlimit commercialization of our drug candidates. Even a timely basis, onsuccessful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

Our inability to obtain and retain sufficient product liability insurance at an acceptable terms,cost to protect against potential product liability claims could prevent or at all,inhibit the commercialization of products we develop. We intend to obtain product liability insurance covering our clinical trials. Although we will maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies also have various exclusions, and we may be subject to a product liability claim for which we haves no coverage. We may have to curtailpay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and it may not have, or be able to obtain, sufficient capital to pay such amounts.

We may acquire businesses, assets or products, or form strategic alliances, in the developmentfuture, and we may not realize the benefits of a product candidate, reducesuch acquisitions.

We may acquire additional businesses, assets or delay its development programproducts, form strategic alliances or onecreate joint ventures with third parties that we believe will complement or more ofaugment our other development programs, delay its potential development schedule or reduce the scope of research activities, or increase our expenditures and undertake discovery or preclinical development activities at our own expense.existing business. If we fail to enter into collaborations and do not have sufficient fundsacquire businesses with promising markets or expertise to undertake the necessary development activities,technologies, we may not be able to further develop our product candidates or continue to develop our product candidates and our business may be materially and adversely affected.

Future collaborations we may enter into may involverealize the following risks:

Additionally, subject to its contractual obligations to us, if a collaborator of ours is involved in a business combination, the collaborator might deemphasize or terminate the development of any of our product candidates. If one of our collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators and our perception in the business and financial communities could be adversely affected.

If we are unable to maintainsuccessfully integrate them with our collaborations, developmentexisting operations and company culture. We cannot assure you that, following any such acquisition, we will achieve the expected synergies to justify the transaction.

Risks Related to Development, Regulatory Approval and Commercialization

If our studies encounter difficulties or fail to demonstrate safety and efficacy to the satisfaction of our product candidates could be delayedthe FDA and comparable non-U.S. regulators, we may needincur additional resources to develop them. All of the risks relating to product development, regulatory approval and commercialization describedcosts or experience delays in this report also apply to the activities of our collaborators.

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern, and in order to fund our operations and execute our business plan we will require additional financing.

Since inception, we have experienced recurring operating losses and negative cash flows and we expect to continue to generate operating losses and consume significant cash resources for the foreseeable future. Without additional financing, these conditions raise substantial doubt about our ability to continue as a going concern, meaning that we maycompleting, or ultimately be unable to continue operations forcomplete, the foreseeable future or realize assets and discharge liabilities in the ordinary course of operations. As a result, our independent registered public accounting firm included an explanatory paragraph in their report on our consolidated financial statements for the years ended January 31, 2018 and 2017 with respect to this uncertainty. Such an opinion may materially and adversely affect the price per share of our common stock and/or otherwise limit our ability to raise additional funds through the issuance of debt or equity securities or otherwise. Further, the perception that we may be unable to continue as a going concern may impede our ability to raise additional funds or operate our business due to concerns regarding our ability to discharge our contractual obligations.

We have prepared our consolidated financial statements on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. Our consolidated financial statements for the years ended January 31, 2018 and 2017 do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty. Without additional funds, however, we may be unable to continue as a viable entity, in which case our stockholders may lose all or some of their investment in us.

The terms of certain of our prior registered direct offerings may materially and adversely impact our ability to obtain additional financing in the future.

We are subject to certain restrictions and obligations in connection with our registered direct offerings, or RDOs, that were consummated in September 2016, April 2017 and July 2017, which may materially and adversely affect our ability to obtain additional financing in the future. These restrictions and obligations include:

We have also made various representations and warranties to the RDO investors in connection with the RDO Transaction Documents, including those related to solvency, no integrated offerings, maintenance of our stock exchange listing, internal controls, and absence of liens, among others. In the event any of our representations or warranties in the RDO Transaction Documents are determined to be inaccurate, or if we are deemed to have otherwise violated any provisions of the RDO Transaction Documents, we may be found to be in breach of the RDO Transaction Documents. This in turn may result in litigation against us, which could be costly and time-consuming, divert management’s attention and resources, damage our reputation and otherwise harm our business, results of operations and financial condition.

Our business is dependent on the successful development regulatory approval and commercialization of our product candidates, in particular BPX01, BPX04 and BPX03.candidates.

Our portfolio of product candidates includes three clinical-stage drug product candidates, BPX01, a topical antibiotic for the treatment of acne, BPX04, a topical antibiotic for the treatment of rosacea, and BPX03, a molecular iodine tablet for the treatment of moderate to severe, periodic breast pain associated with fibrocystic breast condition, or FBC, and cyclic mastalgia. The success of our business, including our ability to finance our company, form strategic partnerships and generate revenues in the future, will primarily depend on the successful development, regulatory approval and commercialization of these product candidates. In the future, we may become dependent on one or more of our early-stage product candidates or any of our product candidates that we may in-license, acquire or develop. The clinical and commercial success of our product candidates will depend on a number of factors, including the following:

If we are unable to achieve any of the above factors, many of which are beyond our control, in a timely manner or at all, we could experience significant delays or fail to obtain regulatory approvals or commercialize our product candidates. Even if we obtain the necessary regulatory approvals, we may never successfully commercialize any of our product candidates. Accordingly, we may not generate revenue through the sale of our product candidates or any future product candidates sufficient to continue operations.

We have a limited operating history and have yet to recognize more than a de minimis amount of revenue from sales of VI2OLET and have yet to obtain regulatory approvals for any of our product candidates, which makes it difficult to evaluate our future prospects and viability.

Our operations to date have been primarily limited to researching and developing our product candidates and undertaking preclinical studies and clinical trials of our product candidates. While VI2OLET went on the market in December 2014 in online stores and in drug, grocery and retail chains throughout the United States, we have only recognized a de minimis amount of revenue from sales to date. We have also not yet obtained regulatory approvals for any of our product candidates. Consequently, the ability to accurately assess and predict our future operating results or

business prospects is more limited than if we had a longer operating history or FDA-approved products on the market. Our manufacturing agreement for VI2OLET with UPM, requires a minimum annual purchase of approximately $269,000 of iodine supplement tablets. This agreement expires in 2020, and we are required to purchase the minimum annual amount regardless of market demand.  The remaining minimum purchase commitment is $0.9 million through 2020.  We have not recorded an obligation for the minimum purchase amount remaining, since we have determined that a loss on this obligation is not probable based on our market demand analysis.  In the future, we may conclude that an obligation is required as the result of our market demand analysis and record such obligation.  The recording of such obligation would negatively impact the results of our operations in the period recorded.

We currently have limited marketing and sales capabilities. If we are unable to establish sales and marketing capabilities on our own or through third parties, we will be unable to successfully commercialize our product candidates, if approved, or generate product revenue.

To successfully commercialize our product candidates, if approved, in the United States, Canada, the European Union and other jurisdictions we seek to enter, we must build our marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements with third parties to perform these services, and we may not be successful in doing so. Although our employees have experience in the marketing, sale and distribution of pharmaceutical products from prior employment at other companies, we, as a company have limited prior experience in the marketing, sale and distribution of pharmaceutical products, and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the commercialization of these products. We may choose to collaborate with additional third parties that have direct sales forces and established distribution systems, either to augment or in lieu of our own sales force and distribution systems. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize our product candidates. If we are unable to successfully commercialize our product candidates, either on our own or through collaborations with one or more third parties, our business, financial condition, operating results and prospects would suffer.

Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations.

Our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including the following:

In addition, we measure compensation cost for stock-based awards made to employees at the grant date of the award, based on the fair value of the award as determined by our board of directors, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing these awards change over time, including our underlying stock price and stock price volatility, the magnitude of the expense that we must recognize may vary significantly.

Our ability to utilize our net operating loss, or NOL, carryforwards and research and development income tax credit carryforwards may be limited.

We have significant NOL carryforwards available to reduce future taxable income, if any, for federal and California state income tax purposes. If not utilized, both the federal and California state NOL carryforwards will begin expiring in 2030. Under Section 382 of the Internal Revenue Code of 1986, as amended, or Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be limited. We believe that, with the transactions that have occurred over the past three years, we may have triggered an “ownership change” limitation. We have not conducted a formal NOL carryforward analysis.  We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre-change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOL carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

Risks Related to Development and Commercialization of Our Product Candidates and Regulatory Approval and Other Legal Compliance Matters

We rely on a single, qualified supplier to manufacture each of our products or product candidates.

We rely on one third-party manufacturer for our product and product candidate manufacturing needs. Currently, we engage with DPT, a subsidiary of Mylan N.V., as our clinical contract manufacturer for BPX01 and BPX04.  We have identified a qualified second vendor to carry out the manufacturing and testing of our clinical and commercial supplies and are working on vendor assessments.  UPM manufactures iodine supplement tablets for VI2OLET.

Each of these third-party manufacturers is required by law to comply with the FDA’s regulations, including the applicable cGMP regulations for the type of product manufactured. These regulations set forth standards for both quality assurance and quality control. Third-party manufacturers also must maintain records and other documentation as required by applicable laws and regulations. In addition to a legal obligation to comply, the manufacturer is contractually obligated to comply with all applicable laws and regulations. However, although we are responsible for ensuring compliance with applicable laws and regulations, including cGMPs, we cannot guarantee that each of our manufacturing partners will so comply. Failure of either manufacturer to maintain compliance with applicable laws and regulations could result in delayed or rejected clinical studies, decreased sales of our products, decreased revenues and reputational harm to us and may subject us to sanctions by the FDA, including a request for a voluntary recall, warning letter, seizure of products, injunctions prohibiting some or all further sales and/or recalling product already on the market, possible decree imposing substantial fines, preclusion of government contracts, import alerts and criminal liability for us and our individual employees. In addition, failure of a contract manufacturer for a product undergoing review by the FDA to maintain an acceptable cGMP compliance status could result in a decision by the FDA not to approve any pending NDA.

Our manufacturing contract with DPT is a short-term agreement.  Our commercial supply agreement with UPM is through 2020. We are dependent upon renewing agreements with each of our third-party manufacturers or finding replacement manufacturers to satisfy our requirements. If we do not renew our agreements with our manufacturing partners, there can be no assurance that we will be able to find or engage a replacement manufacturer on a timely basis on acceptable terms, if at all. As a result, we cannot be certain that manufacturing sources will continue to be available or that we can continue to outsource the manufacturing of our products on commercially reasonable or acceptable terms. Further, due to the short-term nature of our agreement, our expenses for manufacturing are not fixed and may change from contract to contract. If the cost of production increases, our gross margins could be negatively affected.

In addition, we rely on our outside manufacturers to provide us with an adequate and reliable supply of our products on a timely basis and in accordance with good manufacturing standards and applicable product specifications. As a result, we are subject to and have little or no control over delays and quality control lapses that our third-party manufacturers may suffer.

We and our third-party manufacturers rely on a limited number of suppliers of the raw materials of our products. A disruption in supply of raw material would be disruptive to our inventory supply.

We and the manufacturers of our products rely on suppliers of raw materials used in the production of our products. Some of these materials are available from only one source. We try to maintain inventory levels that are no greater than necessary to meet our current projections, which could have the effect of exacerbating supply problems. Any interruption in the supply of finished products could hinder our ability to distribute timely our finished products. If we are unable to obtain adequate product supplies to satisfy our customers’ orders, we may lose such orders and, possibly, our customers. This, in turn, could result in a loss of our market share and a corresponding reduction in our revenues. In addition, any disruption in the supply of raw materials or an increase in the cost of raw materials to our manufacturers could have a significant effect on their ability to supply us with our products, which would adversely affect our financial condition and operating results.

Clinical drug development is costly, time-consuming and uncertain, and we may suffer setbacks in our clinical development program that could harm our business.

Clinical drug development for our product candidates is costly, time-consuming and uncertain. Our product candidates are in various stages of development and while we expect that clinical trials for these product candidates will continue for several years, such trials may take significantly longer than expected to complete. In addition, we, the FDA,

an IRB, or other regulatory authorities, including state and local agencies and counterpart agencies in foreign countries, may suspend, delay, require modifications to or terminate our clinical trials at any time, for various reasons, including:

As with other pharmaceutical and biotechnology companies, we may suffer significant setbacks in our clinical trials despite promising results in earlier trials. In the event that we abandon or experience delays in the clinical development efforts related to our product candidates, we may not be able to execute on our business plan effectively and our business, financial condition, operating results and prospects may be harmed.

We may be unable to obtain regulatory approval for our clinical-stage product candidates or other early-stage product candidates under applicable regulatory requirements. The FDA and foreign regulatory bodies have substantial discretion in the approval process, including the ability to delay, limit or deny approval of product candidates. The delay, limitation or denial of any regulatory approval would adversely impact commercialization, our potential to generate revenue, our business and our operating results.

We are not permitted to commercialize, market, promote or sell any of our current product candidatescandidate in the United States until we receivewithout obtaining marketing approval of an NDA or BLA from the FDA. We are also not permitted to market any of our current product candidates in any foreign countries until we receive the requisite approval from the applicableComparable non-U.S. regulatory authorities ofimpose similar restrictions. We may never receive such countries. Failure to obtain such regulatory approvals will delay or prevent us from commercializing any of our current or future product candidates.

To gain approval to market a new drug, weapprovals. We must provide the FDA and/or foreign regulatory authorities with, among other things,complete extensive preclinical development and clinical data that adequately demonstratesstudies to demonstrate the safety and efficacy of the drug in its intended indication and information to demonstrate the adequacy of the manufacturing methods to assure the drug’s identity, strength, quality and purity. The development and approval of new drugour product candidates involves a long,in humans before we will be able to obtain these approvals.

Clinical testing is expensive, and uncertain process, and delay or failure can occur at any stage. A number of companies in the pharmaceutical and biopharmaceutical industries have suffered significant setbacks in clinical trials, including in Phase 3 clinical development, even after promising results in earlier preclinical studies or clinical trials. These setbacks have been caused by, among other things, observations during clinical trials regarding safety or efficacy, such as previously unreported adverse events.  Success in preclinical testing and early clinical trials does not ensure success in later clinical trials, and the results of clinical trials by other parties may not be indicative of the results in trials we may conduct. Further, different results may be achieved depending upon which analysis population is used to analyze results. Regardless of the outcome of any Phase 2 trials, our Phase 3 trials, if commenced, may not be successful. For example, we reported that findings on a secondary endpoint in our Phase 2b clinical trial of BPX01, the reduction in Investigator’s Global Assessment, or IGA, which was defined as the proportion of subjects with at least a two-grade reduction in IGA to clear “0” or almost clear “1”, were not statistically significant.  While the BPX01 2% arm demonstrated a clear numerical trend compared to vehicle, the BPX01 1% arm showed a smaller separation from vehicle.  While this trial was not powered to demonstrate statistical significance for IGA and, therefore, IGA was not expected to be statistically significant, there is no guarantee that our Phase 3 trial, if commenced, will produce statistically significant results on IGA, which will serve as a co-primary endpoint with inflammatory lesion reduction despite our plans to adequately power the Phase 3 study to achieve this endpoint.  In addition, topline results of a clinical trial do not necessarily predict final results. For example, the topline results of the Phase 2b clinical study of BPX01 1% and 2% reported that both concentrations statistically significantly reduced inflammatory lesions, the primary endpoint.  The information reflected our preliminary review of the topline primary efficacy results based solely upon information available to us at that time.  Since topline reporting, adjustments for multiple comparisons were made, resulting in a change to the p-value for the 1% and 2% concentrations, rendering the results of the 1% concentration no longer statistically significant.  It is always a risk that further review of results may change the conclusions drawn from the preliminary review to less positive results than we anticipated. 

In the case of our topical product candidates, BPX01 and BPX04, we are seeking to deliver sufficient concentrations of the API through the skin barrier to the targeted dermal tissue to achieve the intended therapeutic effect. The topical route of administration may involve new dosage forms, which can be difficult to developdesign and manufactureimplement, can take many years to complete, can fail for many reasons, and may raise novel regulatory issues and result in development or review delays. For example, the antibiotic delivered in BPX01 and BPX04 is difficultinherently uncertain as to stabilize and prone to epimerization in most formulations and delivery systems and, as such, presents great challenges for transepidermal delivery.outcome. We believe potential competitors have attempted to resolve these problems by stabilizing the antibiotic in certain lipophilic formulation, but the solutions either failed to adequately deliver the antibiotic or required overly high concentration (i.e., dosage) for clinical efficacy. As a result, safety and efficacy of BPX01 and BPX04 may be difficult to establish.

In the case of our research-phase product candidate, BPX02, because it is a biological product, it may be difficult to characterize the clinically active component(s) by testing methods available in the laboratory, and some of the components of the finished product may be unknown. Therefore, to ensure product consistency, quality, and purity, we must ensure the manufacturing process remains substantially the same over time. The systems used to produce biological products can be sensitive to very minor changes in the manufacturing process. Small process differences can significantly affect the nature of the finished biological product, and more importantly, the way it functions in the body. We will have to tightly control the source and nature of starting materials, and consistently employ hundreds of process

controls that assure predictable manufacturing outcomes. Our ability to ensure that the manufacturing process remains stable over time may be difficult to establish. In addition, for a novel biological product, there may be uncertainties regarding the size and design of the clinical trials to establish safety, efficacy, purity or potency, and there are no assurances that data generated in any clinical trials we might conduct will be acceptablenot previously submitted an NDA to the FDA or foreign regulatory bodies to support marketing approval.

The FDA and foreign regulatory bodies have substantial discretion in thesimilar drug approval process, including thefilings to comparable non-U.S. regulatory authorities for any product candidates.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us and impair our ability to delay, limitgenerate revenues from product sales, regulatory and commercialization milestones and royalties. In addition, if (1) we are required to conduct additional clinical studies or deny approvalother testing of our product candidates for many reasons. The FDAbeyond the studies and testing that we contemplate, (2) we are unable to successfully complete clinical studies of our product candidates or other testing, (3) the applicable foreign regulatory bodyresults of these studies or tests are unfavorable, uncertain or are only modestly favorable, or (4) there are unacceptable safety concerns associated with our product candidates, we, in addition to incurring additional costs, may:

Any delay, limitation or denial of any regulatory approval would adversely impact commercialization, our potential to generate revenue, our businessEnrollment and our operating results.

Our only commercialized product, VI2OLET, is subject to regulation by U.S. and international regulatory authorities.

Our first and only commercialized product, launched in December 2014, is our women’s health dietary supplement distributed under the brand name “VI2OLET” iodine. We recently entered into an agreement to distribute VI2OLET in Mexico and Central America. The processing, formulation, safety, manufacturing, packaging, labeling, advertising and distribution of VI2OLET is subject to federal laws and regulation by one or more federal agencies, including the FDA, the FTC, the CPSC, the United States Department of Agriculture and the Environmental Protection Agency. These activities are also regulated by various state, local and international laws and agencies of the states and localities in which our products are or may be sold including non-governmental entities such as NAD. The NAD oversees an industry sponsored, self-regulatory system that permits competitors to resolve disputes over advertising claims. The NAD has no enforcement authority of its own, but may refer matters that appear to violate the FTC Act or the FDC Act to the FTC or the FDA for further action, as appropriate.

All facilities that manufacture, process, package, or store food for human consumption must register with the FDA as a food facility. A dietary supplement is considered a food substance under the FDC Act and FDA regulations. We are registered with the FDA as a food facility and we renew our registration every two years. The FDA annually schedules inspections at a number of registered food facilities to determine whether the inspected facilities are in compliance with food-related FDA regulations. While the FDA has not yet inspected or scheduled an upcoming inspection at our facility, the FDA could choose to conduct such an inspection at any time. If the FDA observed any evidence of violation or noncompliance during an inspection, we would be required to respond adequately to the observations, typically by developing and executing appropriate corrective and preventive actions. Any inspection of our facility could entail inspection of our third-party manufacturer, UPM, which is responsible for production of VI₂OLET under the terms of our commercial supply agreement. Any observations related to the third-party manufacturer as a result of an FDA inspection may require the third-party manufacturer to implement significant corrective or preventive measures related to its production process, which could impact our commercial supply of VI₂OLET. Any uncorrected violation or noncompliance could lead to further regulatory action by the FDA.

Although dietary supplements may generally be marketed without FDA premarket review and approval, the FDA regulates, among other things, the manufacturing, labeling, and claims for such products. We cannot represent, expressly or implicitly, that a dietary supplement will diagnose, cure, mitigate, treat or prevent a disease, or the FDA will consider such products as drugs. The FDA could determine that a particular statement of nutritional support is an unacceptable drug claim, is not substantiated, is an unauthorized version of a health claim or that the product is otherwise misbranded and/or adulterated. In addition, claims on labeling and promotional materials for our dietary supplement products could be challenged by the FDA, the FTC, self-regulatory bodies such as the NAD, competitors or consumers. For example, we make certain claims relating to VI2OLET that may be alleged to be non-compliant with FDA or FTC regulations. If the FDA or the FTC determines that particular claims relating to our products are violative, we could be subject to regulatory action, such as investigations, warning or untitled letters and cease and desist orders, corrective labeling or advertising orders, consumer redress (for example, offers to repurchase products previously sold to consumers), injunctive relief or product seizures, civil penalties or criminal prosecution. Enforcement action by the FDA or the FTC, or class action lawsuits stemming from an enforcement action or allegation, could materially and adversely affect our business, financial position and operating results and could cause the market value of our common stock to decline.

In addition, the FDA regulates the manufacturing and safety of dietary supplements. The manufacturing of dietary supplements is subject to dietary supplement cGMPs. We are also required to submit to the FDA serious adverse reports, and the FDA may determine that a particular dietary supplement or ingredient presents an unacceptable health risk based on the required submission of this information or other information about the product. During development of BPX03 by the prior sponsor, the FDA expressed concern about the potential for teratogenicity of molecular iodine in a use similar to that of VI2OLET. If the FDA determines that our dietary supplement is unsafe or adulterated or otherwise in violation of FDA requirements, the FDA could take regulatory action as described above.

From time to time, the above-mentioned agencies and lawmakers consider the implementation of more stringent laws and regulations of dietary supplements and other products. These developments could require reformulation of some products to meet new standards, recalls or discontinuance of some products unsusceptible to reformulation, additional recordkeeping requirements, increased documentation of the properties of some products, additional or different labeling, additional scientific substantiation or other new requirements. Any of these developments could increase our costs significantly. In addition, regulators’ evolving interpretation of existing laws could have similar

effects. For example, in August 2016, the FDA issued updated draft guidance explaining its interpretation of the requirement for the notification to the FDA of certain new dietary ingredients. Although FDA guidance is not mandatory, and companies are free to use an alternative approach if the approach satisfies the requirements of applicable laws and regulations, FDA guidance is a strong indication of the FDA’s current thinking on the topic discussed in the guidance, including its position on enforcement. At this time, it is difficult to determine whether the draft guidance, if finalized, would have a material impact on our operations. However, if the FDA were to enforce the applicable statutes and regulations in accordance with the draft guidance as written, we would incur significant additional expenses, which could materially and adversely affect our business in several ways, including, but not limited to, the enjoinment of manufacturing of our products if and until the FDA determines that we are in compliance and can resume manufacturing, which would reduce our growth prospects.

Delays or difficulties in the enrollmentretention of patients in clinical trials may result in additional costsis an expensive and delays intime-consuming process and could be made more difficult or rendered impossible by multiple factors outside our ability to generate significant revenues, and may delay or prevent our receipt of any regulatory approvals necessary to commercialize our planned and future products.control.

We may notencounter delays or difficulties in enrolling, or be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. In addition, some of our competitors are currently conducting clinical trials for product candidates that treat the same indications as our product candidates, and patients who are otherwise eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates.

Patient enrollment is affected by other factors including:

Our inability to enroll, a sufficient number of patients forto complete any of our clinical trials would result in significant delays, could require uson its current timelines, or at all, and even once enrolled we may be unable to abandon one or more clinical trials altogether and could delay or preventretain a sufficient number of patients to complete any of our receipt of necessary regulatory approvals.trials. Enrollment delays in our clinical trials may resultbe slower than we anticipate, leading to delays in increasedour development coststimelines. For example, we may face difficulty enrolling or maintaining a sufficient number of patients in our clinical trials due to the existing alternative treatments approved for our product candidates, which would cause the valuetreatment of any of our companytargeted indications, such as topical corticosteroids or topical steroid-free therapies for atopic dermatitis or psoriasis, as patients may decline to declineenroll or decide to withdraw from our clinical trials due to the risk of receiving placebo. Patient enrollment and impederetention in clinical trials depends on many factors, including the size of the patient population, the nature of the trial protocol, our ability to recruit clinical trial investigators with the appropriate competencies and experience, the existing body of safety and efficacy data with respect to the study drug, the number and nature of competing treatments and ongoing clinical trials of competing drugs for the same indication, the proximity of patients to clinical sites, the eligibility criteria for the trial and the proportion of patients screened that meets those criteria, our ability to obtain additional financing.and maintain patient consents, and our ability to successfully complete prerequisite studies before enrolling certain patient populations.

We intend to pursue Section 505(b)(2) regulatory approval filings with the FDA for at least one of our product candidates. If the FDA concludes that certain

Furthermore, any negative results or new safety signals we may report in clinical trials of our product candidates failmay make it difficult or impossible to satisfy the requirements under Section 505(b)(2), or if the requirements for such product candidates under Section 505(b)(2) are not as we expect, the approval pathway for such productrecruit and retain patients in other clinical trials. Similarly, negative results reported by our competitors about their drug candidates may take significantly longer, cost substantially more and entail greater complications and risks than anticipated and,negatively affect patient recruitment in either case, may not be successful.  In addition, if under certain circumstances, exclusivityour clinical trials. Also, marketing authorization of competitors would delay approvalin this same class of drugs may impair our product candidates, then we may pursue approval through the Section 505(b)(1) regulatory pathway, which may require usability to conduct additional preclinical or clinical trials or obtain a right to reference the preclinical or clinical data of others.

We are currently developing two product candidates, BPX01 and BPX04, for which we intend to seek FDA approval through the Section 505(b)(2) regulatory pathway, and may decide to seek FDA approval for other early-phase products through the Section 505(b)(2) regulatory pathway in the future. A Section 505(b)(2) NDA is a special type of NDA that enables the applicant to rely, in part, on the FDA’s findings of safety and efficacy of an existing previously

approved product, or published literature, in support of its application. Section 505(b)(2) NDAs often provide an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. Such filings involve significant filing costs, including filing fees.

BPX01 and BPX04 are a topical formulations of minocycline (Solodyn), a previously approved oral antibiotic. Reliance on safety findings made by the FDA in approving Solodyn, the antibiotic we will reference in our NDA, could expedite the development program for our product candidates by decreasing the amount of preclinical or clinical data that we would need to generate in order to obtain FDA approval. BPX01’s and BPX04’s route of administration and dosage form, however, differ from Solodyn’s and, as a result, the FDA may not permit us to use this approach to regulatory approval. If the FDA does not allow us to pursue the Section 505(b)(2) regulatory pathway as anticipated, or if the Section 505(b)(2) regulatory pathway fails to significantly decrease the amount of testing we must conduct, we may need to conduct additional preclinical or clinical trials, provide additional data and information and meet additional standards to obtain regulatory approval. In such case, the time and financial resources required to obtain FDA approval for BPX01 and BPX04, or any other product candidate for which we seek approval pursuant to the Section 505(b)(2) regulatory pathway in the future, and complications and risks associated with these product candidates, likely would increase substantially. Moreover, our inability to pursue the Section 505(b)(2) regulatory pathway could prevent us from introducing our product candidatesenroll patients into the market prior to our competitors, which could harm our competitive position and prospects. Further, even if the FDA allows us to pursue the Section 505(b)(2) regulatory pathway, we cannot guarantee that it would ultimately lead to faster product development, and our product candidates may not receive the requisite approvals for commercialization.

In addition, notwithstanding the approval of a number of products by the FDA under Section 505(b)(2) over the last few years, certain competitors and others have objected to the FDA’s interpretation of Section 505(b)(2). If the FDA’s interpretation of Section 505(b)(2) is successfully challenged, the FDA may be required to change its Section 505(b)(2) policies and practices, which could delay or even prevent the FDA from approving any NDA that we submit under Section 505(b)(2).

Furthermore, the pharmaceutical industry is highly competitive, and Section 505(b)(2) NDAs are subject to special requirements designed to protect the patent rights of sponsors of previously approved drugs referenced in a Section 505(b)(2) NDA. As part of any NDA we would submit to the FDA for BPX01, we would be required to make certifications to all patents listed in the Orange Book for Solodyn, the listed drug we intend to reference in our NDA. There are currently six patents listed in the Orange Book for Solodyn. If we make a Paragraph IV certification to any of the patents listed in the Orange Book, those patent certifications may give rise to patent litigation and mandatory delays in approval of our NDA for up to 30 months depending on the outcome of any litigation. It is not uncommon for a manufacturer of an approved referenced product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approval requirements for, pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product. However, even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition.

Furthermore, award of three-year exclusivity by FDA to a competitor with a Section 505(b)(2) NDA could delay approval of a product candidate of ours submitted pursuant to Section 505(b)(2) of the FDC Act if the FDA were to determine that the products have overlapping conditions of approval, even if our Section 505(b)(2) NDA does not rely on the competing Section 505(b)(2) NDA.  Alternatively, we may pursue approval through the Section 505(b)(1) regulatory pathway, which may require us to conduct additional preclinical or clinical trials or obtain a right to reference the preclinical or clinical data of others.  These alternatives may increase the time and/or financial resources required to obtain approval.

Use of PROs in our BPX03 clinical trials may delay the development of BPX03 or increase our development costs.

Due to the difficulty of objectively measuring the symptoms of FBC, patient-reported outcome instruments, or PROs, may have an important role in the development and regulatory approval of our BPX03 product candidate. PROs involve patients’ subjective assessments of efficacy, and this subjectivity increases the uncertainty in determining clinical endpoints. Such assessments can be influenced by factors outside of our control, and can vary widely from day-to-day for a particular patient, and from patient-to-patient and site-to-site within a clinical trial. Furthermore, if we pursue a Phase 3 clinical program for BPX03, we anticipate that we would use PROs in such  a program, and if the FDA does not accept or requires changes to the PRO, this could delay clinical development of BPX03, increase our costs and necessitate additional clinical trials.

We have limited experience in the conduct of clinical trials and have never obtained approval of any product candidates, and may be unable to do so successfully.

As a company, we have limited experience in conducting clinical trials or progressing a product candidate through to regulatory approval. In part because of this lack of experience, our clinical trials, may requiredelaying or potentially preventing it from completing recruitment of one or more time and incur greater costs than we anticipate. We cannot be certain that planned clinical trials will begin or conclude on time, if at all. Large-scale trials would require significant additional financial and management resources, and reliance on third-party clinical investigators, CROs and/or consultants. Any performance failure on the part of such third parties could delay clinical development or delay or prevent us from obtaining regulatory approval or commercializing our current or future product candidates, depriving us of potential product revenue and resulting in additional losses.

Any product candidates that we commercialize will be subject to ongoing and continued regulatory review.

Even after we achieve U.S. regulatory approval for a product candidate, if any, we will be subject to continued regulatory review and compliance obligations. For example, the FDA may impose significant restrictions on the approved indicated uses for which our product candidates may be marketed or on the conditions of approval. A product candidate’s approval may contain requirements for potentially costly post-approval studies and surveillance, including Phase 4 clinical trials or a REMS to monitor the safety and efficacy of the product. We will also be subject to ongoing FDA obligations and continued regulatory review with respect to, among other things, the manufacturing, processing, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for our product candidates. These requirements include submissions of safety and other post-marketing information and reports, registration, continued compliance with the FDA’s good clinical practice, or GCP, requirements and good laboratory practice requirements, which are regulations and guidelines the FDA would apply to all of our product candidatestrials.

Delays or failures in clinical and preclinical development, along with any clinical trials that we conduct post-approval, and continued compliance with the FDA’s cGMP requirements pursuantplanned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on our ability to which manufacturing facilities are subject to continual review and periodic inspections by the FDA. To the extent that a product candidate is approved for sale in other countries, we may be subject to similar restrictions and requirements imposed by laws and government regulators in those countries.

If we,develop our product candidates or the manufacturing facilities for our product candidates failcould render further development impossible. In addition, we expect to comply with applicable regulatory requirements, a regulatory agency may:

The regulations, policies or guidance of the FDArely on CROs and other applicable government agencies may changeclinical trial sites to ensure proper and new or additional statutes or government regulations may prevent or delay regulatory approvaltimely conduct of our product candidates or further restrict or regulate post-approval activities. We cannot predict the likelihood, nature or extent of adverse government regulation that may arise from future legislation or administrative action, eitherclinical trials, and, while we intend to enter into agreements governing their services, we will be limited in the United States or abroad. If we are not able to achieve and maintain regulatory compliance, we may not be permitted to market our product candidates, which would materially and adversely affect our ability to generate revenuecompel their actual performance.

We face significant competition from other biotechnology and achieve or maintain profitability.

Our product candidates may cause serious or undesirable side effects or possess other unexpected propertiespharmaceutical companies that could delay or prevent their regulatory approval, limit the commercial profile of approved labeling or result in post-approval regulatory action.

Unforeseen side effects from any of our product candidates could arise either during clinical development or, if approved, after marketing such product. Undesirable side effects caused by product candidates could cause us or regulatory authorities to interrupt, modify, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or comparable foreign authorities. Results of clinical trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of product candidates for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in product liability claims. Any of these occurrences may harm our business, financial condition, operating results and prospects.

Additionally, if we or others identify undesirable side effects, or other previously unknown problems, caused by our product candidates after obtaining U.S. or foreign regulatory approval or other products with the same or related active ingredients, a number of potentially negative consequences could result, including:

Any of the above events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing our product candidates.

If any of our product candidatescurrently are approved for marketing andtargeting medical dermatological indications that we are found to have improperly promoted off-label uses, or if physicians misuse our products or use our products off-label, we may become subject to prohibitions on the sale or marketing of our products, product liability claims and significant fines, penalties and sanctions, and our brand and reputation could be harmed.

The FDA and other regulatory agencies strictly regulate the marketing and promotional claims that are made about drug products. In particular, a product may not be promoted for uses or indications that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we are found to have promoted off-label uses of any of our product candidates, we may receive warning or untitled letters and become subject to significant liability, which would materially harm our business. Both federal and state governments have levied large civil and criminal fines against companies for alleged improper promotion and have enjoined several companies from engaging in off-label promotion. If we become the target of such an investigation or prosecution based on our marketing and promotional practices, we could face similar sanctions, which would materially harm our business. In addition, management’s attention could be diverted from our business operations, significant legal expenses could be incurred and our brand and reputation could be damaged. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we are deemed by the FDA to have engaged in the promotion of our products for off-label use, we could be subject to FDA regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they determine our business activities constitute promotion of an off-label use, which could result in significant penalties, including criminal, civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs and the curtailment or restructuring of our operations.

We cannot, however, prevent a physician from using our product candidates in ways that fall outside the scope of the approved indications, as he or she may deem appropriate in his or her medical judgment. Physicians may also misuse our product candidates or use improper techniques, which may lead to adverse results, side effects or injury and, potentially, subsequent product liability claims. Furthermore, the use of our product candidates for indications other than those cleared by the FDA and/or other regulatory agencies may not effectively treat such conditions, which could harm our brand and reputation among both physicians and patients.

We may also be subject to healthcare laws, regulation and enforcement and our failure to comply with those laws could adversely affect our business, operations and financial condition.

Certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We are subject to regulation by both the federal government and the states in which we conduct our business. The laws and regulations that may affect our ability to operate include:

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent health care reform legislation has strengthened these laws. For example, the ACA, among other things, amended the intent requirement of the federal anti-kickback statute and certain criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the laws described above or any other governmental laws or regulations that apply to us, we may be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment or the curtailment or restructuring of our operations, any of which could materially and adversely affect our ability to operate our business and our financial results.

Our employees, independent contractors, principal investigators, consultants, vendors and CROs may become insolvent or engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, principal investigators, consultants, vendors and CROs may become insolvent or engage in fraudulent or other illegal activity. Misconduct by these persons could include intentional, reckless or negligent conduct or unauthorized activity that violates: laws or regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA or foreign regulatory authorities; manufacturing standards; federal, state and foreign healthcare fraud and abuse laws and data privacy; or laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and other business arrangements in the healthcare industry are subject to extensive laws intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide range of business activities, including

research, manufacturing, distribution, pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials, or illegal misappropriation of drug product, which could result in regulatory sanctions or other actions or lawsuits stemming from a failure to comply with such laws or regulations, and serious harm to our reputation. In addition, federal procurement laws impose substantial penalties for misconduct in connection with government contracts and require certain contractors to maintain a code of business ethics and conduct. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, FDA debarment, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our businessstudying, and our operating results.

Evenresults will suffer if our current product candidates or any future product candidates obtain regulatory approval, they maywe fail to achieve the broad degree of physician and patient adoption and use necessary for commercial success.compete effectively.

The commercial success of any of our current or futuremarkets for dermatological therapies are competitive and are characterized by significant technological development and new product candidates, if approved, will depend significantlyintroduction. For example, there are several large and small pharmaceutical companies focused on the broad adoption and use of the resulting product by physicians and patients for approved indications, and may not be commercially successful. The degree and rate of physician and patient adoption of our current or future product candidates, if approved, will depend on a number of factors, including:

If any of our current or future product candidates are approved for use but fail to achieve the broad degree of physician and patient adoption necessary for commercial success, our operating results and financial condition will be adversely affected, which may delay, prevent or limit our ability to generate revenue and continue our operations.

If we are unable to achieve and maintain coverage and adequate levels of reimbursement for any of our product candidates for which we receive regulatory approval, or any future products we may seek to commercialize, their commercial success may be severely hindered.

As to any of our product candidates that become available by prescription only, our success will depend on the availability of coverage and adequate reimbursementdelivering therapeutics for our product from third-party payors. Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. The availability of coveragetargeted inflammatory and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and private third-party payors is critical to new product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. If any of our product candidates fail to demonstrate attractive efficacy profiles, they may not qualify for coverage and reimbursement. In addition, certain currently approved therapies for the treatment ofmedical dermatological and women’s health—related issues have received limited or no reimbursement coverage by insurers and, accordingly, coverage for BPX03, BPX01 and BPX04, if approved, may not be available. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate or may require co-payments that patients find unacceptably high. Patients are unlikely to use our prescription-only products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products.

In addition, the market for certain of our product candidates will depend significantly on access to third-party payors’ drug formularies, or lists of medications for which third-party payors provide coverage and reimbursement. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies. Also, third-party payors may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent or other alternative is available.

Further, third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the United States, although private third-party payors tend to follow Medicare, no uniform policy of coverage and reimbursement for drug products exists among third-party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our product candidates to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions in both the United States and in international markets. Third-party coverage and reimbursement for any of our product candidates for which we may receive regulatory approval may not be available or adequate in either the United States or international markets, which could harm our business, financial condition, operating results and prospects.

Our product candidates, if approved, will face significant competition and our failure to compete effectively may prevent us from achieving significant market penetration.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on developing proprietary therapeutics. Numerous companies are engaged in the development,

patenting, manufacturing and marketing of healthcare products competitive with those that we are developing. We face competition from a number of sources, such as pharmaceutical companies, including generic drug companies, biotechnology companies and academic and research institutions, many of which have greater financial resources, marketing capabilities, sales forces, manufacturing capabilities, research and development capabilities, clinical trial expertise, intellectual property portfolios, experience in obtaining patents and regulatory approvals for product candidates and other resources than us. Some of the companies that offer competing products also have a broad range of other product offerings, large direct sales forces and long-term customer relationships with our target physicians, which could inhibit our market penetration efforts. In addition, certain of our product candidates, if approved, may compete with other dermatological products, including OTC treatments, for a share of some patients’ discretionary budgets and for physicians’ attention within their clinical practices.

indications. We anticipate that, if we obtain regulatory approval of our product candidates, we will face significant competition from other approved therapies andor drugs that become available in the future for the treatment of our target indications that we are studying. If approved, our product candidates may need toalso compete with unregulated, unapproved and off-label treatments. Even if another branded or generic product or an over-the-counter, or OTC, product is less effective than our product candidates, a less effective branded, generic or OTC product may be more quickly adopted by physicians and patients than our competing product candidates based upon cost or convenience. Certain of our product candidates, if approved, will present novel therapeutic approaches for the approved indications and will have to compete with existing therapies, some of which are widely known and accepted by physicians and patients. To compete successfully in this market, we will have to demonstrate that the relative cost, safety and efficacy of our approved products, if any, provide an attractive alternative to existing and other new therapies.therapies to gain a share of some patients' discretionary budgets and for physicians' attention within their clinical practices. Some of the companies that offer competing products also have a broad range of other product offerings, large direct sales forces and long-term customer relationships with our target physicians, which could inhibit our market penetration efforts. Such competition could lead to reduced market share for our product candidates and contribute to downward pressure on the pricing of our product candidates, which could harm our business, financial condition, operating results and prospects.

We are aware of several companies that are working to develop drugs that would compete against our product candidates, such as Mayne Pharma Group Limited, which is developing trifarotene for lamellar ichthyosis, Krystal Biotech, Inc., which is developing KB105 for transglutaminase-1 deficient autosomal recessive congenital ichthyosis, and Nobelpharma Co., Ltd. and Aucta Pharmaceuticals, Inc., which are developing topical rapamycin for FAs in TSC.

Many of our existing or potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of product candidates, as well as in obtaining regulatory approvals of those product candidates in the United States and in foreign countries. Many of our current and potential future competitors also have significantly more experience commercializing drugs that have been approved for marketing. Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a smaller number of our competitors. Competition may reduce the number and types of patients available to us to participate in clinical trials, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors.

Due to less stringent regulatory requirements in certain foreign countries, there are many more dermatological products and procedures available for use in those international markets than are approved for use in the United States. In certain international markets, there are also fewer limitations on the claims that our competitors can make about the effectiveness of their products and the manner in which they can market them.their products. As a result, we expect to face more competition in these markets than in the United States.

Our product candidates, including BPX01, BPX04 and BPX03, if approved,ability to compete successfully will face intense competition and mostdepend largely on our ability to:

The availability of our competitors have significantly greater resources than we do.

If approved forcompetitors' products could limit the treatment of inflammatory lesions of acne, BPX01 will face direct competition from numerous other topical products such as antimicrobials, retinoids or some combination of the two,demand and the existence of these products may limitprice we are able to charge for any product candidate we develop. The inability to compete with existing or subsequently introduced drugs or OTC treatments would have an adverse impact on our business, financial condition and prospects.

If the market sizeopportunities for BPX01. In addition, BPX01 will compete against oral systemic treatments for acne, which include isotretinoins, antibiotics, antimicrobials and contraceptives, and against a number of approved topical treatments for acne, including branded drugs and generic versions where available as well as treatments for both inflammatory and non-inflammatory lesions of acne. If approved for the treatment of rosacea, BPX04 will face direct competition from numerous other topical products such as azelaic acids, brimonidine and ivermectin creams, and the existence of these products may limit the market size for BPX04. In addition, BPX04 will compete against oral systemic treatments for rosacea which include antibiotics and antimicrobials, and against a number of approved topical treatments for acne, including branded drugs and generic versions where available. If approved for the treatment of FBC, BPX03 will face direct competition from numerous other products such as Danocrine, Tamoxifen and Bromocriptine and the existence of these products may limit the market size for BPX03. Certain alternative treatments offered by competitors may be available at a lower price and may offer greater efficacy or a better safety profile. Even if a generic product or an OTC product is less effective than our product candidates a less effective generic or OTC productare smaller than we believe they are, our revenues may be more quickly adopted by health insurers, physiciansadversely affected and patients than our competing product candidates based upon cost or convenience.

Webusiness may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.

We face an inherent risk of product liability as a result ofsuffer. Because the clinical testingtarget patient populations of our product candidates are small, we must be able to successfully identify patients and capture a significant market share to achieve and maintain profitability.

We focus our research and product development on treatments for orphan dermatology indications. Our projections of both the number of people who have failed other therapies or have limited medical options, are based on estimates. These estimates may prove to be incorrect and new studies may change the estimated incidence or prevalence. The number of patients in the United States and elsewhere may turn out to be lower than expected or may not be otherwise amenable to treatment with our products, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and business. Additionally, because our target patient populations are small, we will face an even greater risk if we commercialize any products. This risk exists even ifbe required to capture a product is approved for commercial sale bysignificant market share to achieve and maintain profitability.

The regulatory approval processes of the FDA and manufacturedcomparable foreign authorities are lengthy, time consuming and inherently unpredictable. Even if we obtain approval for a product candidate in facilities regulated byone country or jurisdiction, we may never obtain approval for or commercialize it in any other jurisdiction, which would limit our ability to realize our full market potential.

Prior to obtaining approval to commercialize any of our product candidates in any jurisdiction, we or our collaborators must demonstrate with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA or an applicablecomparable foreign regulatory authority. Our products andagencies, that such product candidates are designed to affect bodily functionssafe and processes. Any side effects, manufacturing defects, misuse or abuse associated with our product candidates could result in injuryeffective for their intended uses. Results from nonclinical studies and possibly death to a patient. An inability to obtain sufficient insurance coverage on commercially reasonable terms or otherwise to protect against potential product liability claims could inhibit our business.

In addition, a liability claim may be brought against us even if our product candidates merely appear to have caused an injury. Product liability claims may be brought against us by consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our product candidates, among others. If we cannot successfully defend ourselves against product liability claims we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:

Although we maintain product liability insurance coverage for clinical trials our insurance coveragecan be interpreted in different ways. Even if we believe the nonclinical or clinical data for a product candidate are promising, such data may not be sufficient to cover all of our product liability-related expenses or lossessupport approval by the FDA and may not cover us for any expenses or losses we suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost, in sufficient amounts or upon adequate terms to protect us against losses due to product liability, particularly if any of our product candidates receiveother regulatory approval. Further, a successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could decrease our cash and harm our business, financial condition, operating results and prospects.

If we suffer negative publicity concerning the safety of our products, our sales and our reputation and the reputation of our products may be harmed and we may be forced to withdraw products.

Physicians and potential patients may have a number of concerns about the safety of our products, whether or not such concerns have a basis in generally accepted science or peer-reviewed scientific research. Negative publicity concerning our products, whether accurate or inaccurate, could reduce market or governmental acceptance of our products and could result in decreased product demand or product withdrawal. In addition, significant negative publicity could result in an increased number of product liability claims, whether or not these claims are supported by applicable law.

We may choose not to continue developing or commercializing any of our product candidates at any time during development or after approval, which would reduce or eliminate our potential return on investment for those product candidates.

At any time, we may decide to discontinue the development or commercialization of any of our products or product candidates for a variety of reasons, including the appearance of new technologies that render our product obsolete, competition from a competing product or changes in or failure to comply with applicable regulatory requirements. If we terminate a program in which we have invested significant resources, we will not receive any return on our investment and we will have missed the opportunity to allocate those resources to potentially more productive uses.

Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.

authorities. In order to market and sell ourany products in the European Union and many other jurisdictions,any particular jurisdiction, we or our third-party collaborators must obtain separate marketing approvalsestablish and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We or these third parties may not obtain approvals from regulatory authorities outside the United Statesrequirements on a timelycountry-by-country basis if at all.regarding safety and efficacy. Approval by the FDA does not ensure approval by regulatory authorities in any other countriescountry or jurisdictions, and approval by one regulatory authorityjurisdiction outside the United States doesStates. In addition, clinical trials conducted in one country may not ensure approvalbe accepted by regulatory authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. Approval processes vary among countries and can involve additional product testing and validation, as well as additional administrative review periods. Seeking regulatory approval could result in difficulties and costs for us and require additional nonclinical studies or jurisdictionsclinical trials, which could be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or byprevent the FDA. We may not be able to file for marketing approvals and may not receive necessary approvals to commercializeintroduction of our products in those countries. We do not have any market.

Risks Related to Dependence on Third Parties, Employee Matters, Managing Growth and Macroeconomic Conditions

We will need to further increase the size and complexity of our organizationproduct candidates approved for sale in the future,any jurisdiction, including in international markets, and we maydo not have experience difficulties in executing our growth strategy and managing our growth.

Our current management, personnel, systems and facilities are not adequate to support our future growth plans. We will need to further expand our scientific, sales and marketing, operational, financial and other resources to support our planned research, development and commercialization activities.

To manage our operations, growth and various projects effectively, we must:

In addition, we have utilized and continue to utilize the services of part-time outside consultants to perform a number of tasks for us, including tasks related to preclinical and clinical testing. Our growth strategy may also entail expanding our use of consultants to implement these and other tasks going forward. We rely on consultants for certain functions of our business and will need to effectively manage these consultants to ensure that they successfully carry out their contractual obligations and meet expected deadlines. There can be no assurance that we will be able to manage our existing consultants or find other competent outside consultants, as needed, on economically reasonable terms, or at all. If we are not able to manage our growth effectively and expand our organization by hiring new employees and expanding our use of consultants, we might be unable to implement successfully the tasks necessary to execute effectively on our planned research, development and commercialization activities and, accordingly, might fail to achieve our research, development and commercialization goals.

obtaining regulatory approval. If we fail to attractcomply with regulatory requirements in international markets or to obtain and retain managementmaintain required approvals, or if regulatory approvals in international markets are delayed, our target market will be reduced and other key personnel, we may be unable to continue to develop successfully or commercialize our product candidates or otherwise implement our business plan.

Our ability to compete in the highly-competitive pharmaceuticals industry depends upon our ability to attract and retain highly-qualified managerial, scientific, medical, sales and marketing and other personnel. In May 2016, our Chief Executive Officer resigned fromrealize the Company. We are highly dependent on our management and scientific personnel, including: our President and Secretary, Anja Krammer, our Executive Vice President of Research and Technology, Kin F. Chan, PhD, our Chief Financial Officer, Greg Kitchener and our Executive Vice President of Clinical and Regulatory Affairs, AnnaMarie Daniels. We do not maintain “key man” insurance policies on the lives of these individuals or the livesfull market potential of any of our other employees. The loss of the services of any of these individuals, along with other key executives or employees, could impede, delay or prevent the successful development of our product pipeline, completion of our planned clinical trials, commercialization of our product candidates or in-licensing or acquisition of new assets and could negatively impact our ability to successfully implement our business plan. If we lose the services of any of these individuals, we might not be able to find suitable replacements on a timely basis or at all, and our business could be harmed as a result. In order to retain valuable employees at our company, in addition to salary and cash incentives, we provide stock options that vest over time. The value to employees of stock options that vest over timedevelop will be significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract offers from other companies.unrealized.

We might not be able to attract or retain qualified management and other key personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Francisco Bay Area where we are headquartered. We could have difficulty attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention efforts. Many of the other pharmaceutical companies with whom we compete for qualified personnel have greater and other resources, different risk profiles and longer histories in our industry than we do. They may also provide more diverse opportunities and better chances for career advancement. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will harm our ability to implement our business strategy and achieve our business objectives.

In addition, we have scientific and clinical advisors who assist us in formulating our development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

Our failure to successfully in-license, acquire, develop and market additional product candidates or approved products would impair our ability to grow our business.

Our strategy is to in-license and acquire product candidates and we may in-license and acquire commercial-stage products or engage in other strategic transactions. Additional potential transactions that we may consider include a variety of different business arrangements, including spin-offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. We are currently exploring commercial growth opportunities, which may include strategic partnerships with women’s health companies, but there is no guarantee that such opportunities will materialize. The success of this strategy depends partly upon our ability to identify and select promising pharmaceutical product candidates and products, negotiate licensing or acquisition agreements with their current owners and finance these arrangements.

The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex. Other companies, including some with substantially greater financial, marketing, sales and other resources, may compete with us for the license or acquisition of product candidates and approved products. We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. Any such transaction may require us to incur non-recurring or other charges, may increase our near- and long-term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our operations and financial results. We may not be able to acquire the rights to additional product candidates on terms that we find acceptable, or at all.

Further, any product candidate that we acquire may require additional development efforts prior to commercial sale, including preclinical or clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, we cannot provide assurance that any approved products that we acquire will be manufactured or sold profitably or achieve market acceptance.

We currently develop our clinical drug products exclusively in one research and development facility and may utilize this facility in the future to support commercial production if our product candidates are approved. If this or any future facility or our equipment were damaged or destroyed, or if we experience a significant disruption in our operations for any other reason, our ability to continue to operate our business would be materially harmed.

We currently research and develop our product candidates exclusively in a single laboratory located in our corporate headquarters in Menlo Park, California. If this or any future facility were to be damaged, destroyed or otherwise become unable to operate, whether due to war, acts of hostility, earthquakes, fire, floods, hurricanes, storms, tornadoes, other natural disasters, employee malfeasance, terrorist acts, power outages or otherwise, or if performance of our research and development facility is disrupted for any other reason, such an event could delay our clinical trials or, if our product candidates are approved and we choose to manufacture all or any part of them internally, jeopardize our ability to timely manufacture our products, if at all. If we experience delays in achieving our development objectives, or if we are unable to manufacture an approved product within a timeframe that meets our prospective customers’ expectations, our business, prospects, financial results and reputation could be materially harmed.

Currently, we maintain insurance coverage totaling $10 million against product liability claims, $5 million against damage to our property and equipment and $1 million in worker’s compensation coverage, subject to deductibles and other limitations. If we have underestimated our insurance needs with respect to an interruption, or if an interruption is not subject to coverage under our insurance policies, we may not be able to cover our losses.

We may be adversely affected by natural disasters and other catastrophic events, and by man-made problems such as terrorism, that could disrupt our business operations and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate headquarters are located in Menlo Park, California, near major earthquake and fire zones. If a disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as enterprise financial systems, manufacturing resource planning or enterprise quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. Our contract manufacturers’ and suppliers’ facilities are located in multiple locations, where other natural disasters or similar events, such as blizzards, tornadoes, fires, explosions or large-scale accidents or power outages, could severely disrupt our operations and have a material adverse effect on our business, financial condition, operating results and prospects. In addition, acts of terrorism and other geo-political unrest could cause disruptions in our business or the businesses of our partners, manufacturers or the economy as a whole. All of the aforementioned risks may be further increased if we do not implement a disaster recovery plan or our partners’ or manufacturers’ disaster recovery plans prove to be inadequate. To the extent that any of the above should result in delays in the regulatory approval, manufacture, distribution or commercialization of our product candidates, our business, financial condition, operating results and prospects would suffer.

Our business and operations would suffer in the event of failures in our internal computer systems or those of our collaborators.

Despite the implementation of security measures, our internal computer systems and those of our current and any future partners, contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our manufacturing activities, development programs and our business operations. For example, the loss of manufacturing records or clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data

or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further commercialization and development of our products and product candidates could be delayed.

Risks Related to Our Intellectual Property

We may not be able to obtain or enforce patent rightsmaintain orphan drug designation or other intellectual property rights that coverexclusivity for our product candidatescandidates.

We have obtained orphan drug designation for TMB-001, TMB-002 and technologies that are of sufficient breadth to prevent third parties from competing against us.

Our success with respect to ourTMB-003 and may seek additional orphan drug designation for other product candidates and technologies will dependcandidates. Regulatory authorities in part upon our ability to obtain and maintain patent protection in bothsome jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States. Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or the European Medicines Agency ("EMA") from approving another marketing application for the same indication for that drug during that time period. For a product that obtains orphan drug designation on the basis of a plausible hypothesis that it is clinically superior to the same drug that is already approved for the same indication, in order to obtain orphan drug exclusivity upon approval, clinical superiority of such product to this same drug that is already approved for the same orphan indication must be demonstrated. The exclusivity period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or the EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition.

We cannot assure you that any future application with respect to any other countries,product candidate will be granted. If we are unable to preserveobtain orphan drug designation in the United States, we will not be eligible to obtain the period of market exclusivity that could result from orphan drug designation or be afforded the financial incentives associated with orphan drug designation. Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, qualification testing, post-approval clinical data, labeling and promotional activities for such product, will be subject to continual and additional requirements of the FDA and other regulatory authorities.

These requirements include submissions of safety and other post-marketing information, reports, registration and listing requirements, good manufacturing practices, or GMP requirements relating to quality control, quality assurance and corresponding maintenance of records and documents, and recordkeeping. Even if marketing approval of our trade secretsproduct candidates is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to conditions of approval, or contain requirements for costly post-marketing testing and surveillance to prevent third parties from infringing uponmonitor the safety or efficacy of the product. The FDA closely regulates the post-approval marketing and promotion of pharmaceutical products to ensure such products are marketed only for the approved indications and in accordance with the provisions of the approved labeling.

In addition, later discovery of previously unknown problems with our proprietary rights. Our abilityproducts, manufacturing processes, or failure to protectcomply with regulatory requirements, may lead to various adverse results, including:

If any of our product candidates from unauthorizedreceive marketing approval and we, or infringing use by third parties depends in substantial part uponothers, later discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, our ability to market such drug could be compromised.

Clinical studies of our product candidates are conducted in carefully defined subsets of patients who have agreed to enter into clinical studies. Consequently, it is possible that our clinical studies may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If, following approval of any of our product candidates, we, or others, discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, any of the following adverse events could occur:

Any of these events could have a material and adverse effect on our operations and business and could adversely impact the price of our common stock.

The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. If we are found or alleged to have improperly promoted off-label uses, we may become subject to significant liability.

The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products, as our product candidates would be, if approved. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product's approved labeling. If we are found to have promoted such off-label uses, we may become subject to significant liability. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully manage the promotion of our product candidates, if approved, we could become subject to significant liability, which would harm our business and financial condition.

If we obtain approval to commercialize any of our products outside of the United States, a variety of risks associated with international operations could harm its business.

If any of our product candidates is approved for commercialization outside of the United States, we expect that we will be subject to additional risks related to entering into international business relationships, including:

Recently enacted and maintain validfuture legislation may increase the difficulty and enforceable patents.cost for us to obtain marketing approval of and commercialize our drug candidates and affect the prices we may obtain.

Our patent portfolio includes patent applications

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval for our drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell our drug candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We do not know whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our drug candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA's approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In the United States, under the Medicare Modernization Act ("MMA"), Medicare Part D provides coverage to the elderly and disabled for outpatient prescription drugs by approving and subsidizing prescription drug plans offered by private insurers. The MMA also authorizes Medicare Part D prescription drug plans to use formularies where they can limit the number of drugs that will be covered in any therapeutic class. The Part D plans use their formulary leverage to negotiate rebates and other price concessions from drug manufacturers. Also, under the MMA, Medicare Part B provides coverage to the elderly and disabled for physician-administered drugs on the basis of the drug's average sales price, a price that is calculated according to regulatory requirements and that the manufacturer reports to Medicare quarterly.

Both Congress and the Centers for Medicare & Medicaid Services ("CMS"), the agency that administers the Medicare program, from time to time consider legislation, regulations, or other initiatives to reduce drug costs under Medicare Parts B and D. For example, under the 2010 Affordable Care Act (the "ACA"), drug manufacturers are required to provide a significant discount on prescriptions for branded drugs filled while the beneficiary is in the Medicare Part D coverage gap, also known as the "donut hole." There have been legislative proposals to repeal the 'non-interference" provision of the MMA to allow CMS to leverage the Medicare market share to negotiate larger Part D rebates. Further cost reduction efforts could decrease the coverage and price that we receive for our drug candidates and could seriously harm our business. Private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in reimbursement under the Medicare program may result in a similar reduction in payments from private payors.

The ACA is intended to broaden access to health insurance and reduce or constrain the growth of healthcare spending. Further, the ACA imposes a significant annual fee on companies that manufacture or import branded prescription drug products. It also increased the amount of the rebates drug manufacturers must pay to state Medicaid programs, required that Medicaid rebates be paid on managed Medicaid utilization, and increased the additional rebate on "line extensions" (such as extended release formulations) of solid oral dosage forms of branded products. The law also contains substantial provisions affecting fraud and abuse compliance and transparency, which may require us to modify our business practices with healthcare practitioners, and incur substantial costs to ensure compliance.

Certain legislative changes have been proposed and adopted in the United States. States since the ACA was enacted. Several states have adopted or are considering adopting laws that require pharmaceutical companies to provide notice prior to raising prices and to justify price increases. We expect that additional healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of certain development projects and reduce its profitability.

Any patents that wefast track designation or grant of priority review status by the FDA may obtain may be narrow in scope and thus easily circumvented by competitors. Further, in countries where we do not have granted patents, third parties may be ableactually lead to make, usea faster development or sell products identical toregulatory review or substantially similar to,approval process, nor will it assure FDA approval of our product candidates. Additionally, restrictive regulations governingour product candidates may treat indications that do not qualify for priority review vouchers.
