Notes to the Unaudited Condensed Consolidated Financial Statements


 

1. Nature of Business and Liquidity

The terms "MBI" or "the Company", "we", "our", and "us" are used herein to refer to Moleculin Biotech, Inc. MBI is a clinical-stage pharmaceutical company, organized as a Delaware corporation in July 2015, with its2015. The Company's focus is on the treatment of highly resistant cancers viaand viruses through the development of its oncology drug candidates. These candidates all of which are based substantially on license agreements withdiscoveries licensed from The University of Texas System on behalf of the MD Anderson Cancer Center, which we refer to as MD Anderson. MBI formed Moleculin Australia Pty. Ltd., (MAPL), a wholly owned subsidiary in June 2018, to beginperform certain preclinical development in Australia for WP1732, an analog of WP1066.Australia. This enableshas enabled the Company to enjoyrealize the benefits of certain research and development tax credits in Australia. In February 2019, the Company entered into an agreement withsublicensed essentially all of the rights to its technologies in 29 countries in Europe and Asia to WPD Pharmaceuticals Sp.z o.o. (WPD or WPD Pharmaceuticals) in exchange for collaboration on development in Poland. Also in 2019, the Company sublicensed its technologies to Animal Life Sciences, LLCInc. (ALI), where the Company has granted a sublicense to ALI toenable research develop, make, have made, use, offer to sell, sell, export or import and commercialize certain licensed productscommercialization for non-human use and share development data. As part of this agreement, ALI issued to the Company a 10% interest in ALI. ALI converted into

The Company has three core technologies: 1) Annamycin, which the Company refers to as a corporation"next generation" anthracycline; 2) a portfolio of Immune/Transcription Modulators, of which WP1066 is one of the lead molecules; and became Animal Life Sciences, Inc.


Core Technologies - MBI3) a portfolio of Metabolism/Glycosylation Inhibitors, of which WP1122 is the lead molecule. The Company has 3six drug candidates, representing all three core technologies, with 6and three of which have shown human activity in clinical trials. As of the end of 2020, those three drug candidates allaccounted for five clinical trials in the United States (US) and Europe. Two of whichthose trials are based on discoveries made at MD Anderson. These core technologies are 1)externally funded studies of WP1066 in brain tumors. Two internally funded Phase 1 clinical trials, Annamycin 2) its STAT3 Immune/Transcription Modulators, or simply "Immune/Transcription Modulators" WP1066 portfolio and 3) its Metabolism/Glycosylation Inhibitor portfolio, WP1122. The Company’s clinical stage drugs are Annamycin, an anthracycline which is in two Phase 1/2 studies for the treatment of relapsed or refractory acute myeloid leukemia (AML), WP1066, an Immune/Transcription Modulator, which isand WP1220 in a Phase 1 clinical trial in the United States of America (US) for the treatment in glioblastoma, and WP1220, a member of the WP1066 portfolio of drugs, which has completed a Phase 1 proof-of-concept clinical trial for the topical treatment of cutaneous T-cell lymphoma (CTCL), a formwere successfully concluded. An additional Phase 1/2 clinical trial of skin cancer. A fifth Phase 1 trial forAnnamycin in AML is also internally funded and is currently ongoing. In 2021, the treatmentCompany anticipates the initiation of pediatric brain tumors at Emory University has been approved byfour or more new clinical trials in addition to thethree trials continuing from 2020.

In late 2020, MBI received US Food and Drug Administration (FDA) and began recruiting patients in 2020.


The Company believes Annamycin is a "Next Generation Anthracycline" since it is designedclearance to avoid the multidrug resistance mechanisms that typically defeat currently approved anthracyclines, as well as to be non-cardiotoxic, which is the dose limiting toxicity of all currently approved anthracyclines. Annamycin is currently in two Phase 1/2 clinical trials, and preliminary clinical data suggests that it may have the potential to become the first therapy suitable for the majority of relapsed or refractory AML patients regardless of gene mutations. During 2019, these trials have so far demonstrated the safety, including no cardiotoxicity, and has begun to show some initial efficacy. Additionally, preclinical research in animal models at MD Anderson demonstrated that Annamycin is able to significantly improve survival in an aggressive form of triple negative breast cancer metastasized to the lungs. Coupled with research demonstrating that Annamycin is capable of accumulating in the lungs at high levels, this suggests that Annamycin may be well suited to become a treatment for lung-localized tumors.

WP1066 is one of several Immune/Transcription Modulators that appear capable of stimulating immune response to tumors by inhibiting the errant activity of Regulatory T-Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3, c-Myc and HIF-1α. These transcription factors are widely sought targets that may also play a role in the lack of efficacy of immune checkpoint inhibitors in certain resistant tumors. The “proof-of-concept” Phase 1 trial in Poland for WP1220 demonstrated safety and efficacy and preparations to file a Phase 2 IND or its equivalent have begun.

The Company is also developing new prodrugs to exploit the potential uses of inhibitors of glycolysis and glycosylation. Its lead Metabolism/Glycosylation Inhibitor compound, WP1122, provides an opportunity to cut off the fuel supply of tumors and viruses by taking advantage of their overdependence on glucose as compared with healthy cells. New research also points to the potential for the glucose decoy (2-DG) within WP1122 to be capable of enhancing the usefulness of checkpoint inhibitors and inhibiting glycosylation and glycolysis in virally infected cells. In March 2020, we entered into an agreementproceed with an outside research center who will conduct research on WP1122 for antiviral properties against a range of viruses, including Coronavirus. Additional research with other contractors has started.

Drug Candidates - Within the Company's core technologies, it currently has 6 drug candidates representing 3 substantially different approaches to treating cancer. Annamycin is a chemotherapy designed to inhibit the replication of DNA of rapidly dividing cells and is the Company's most mature drug candidate. The Company has trials open in the US and Poland. The USadditional Phase 1 portion of the Phase 1/1b/2 trial reached key safety end points in early 2020 and the Company plans to discuss next steps with the FDA. The Phase 1/2 trial in Poland continues its dose escalation and is in its fifth cohort. So far both trials have proven Annamycin, to date, is safe and is non-cardiotoxic. The trials have demonstrated initial efficacy as well.
7



In addition to Annamycin, the Company has other drug development projects, 2 of which are also in clinical trials:

WP1066 has an approved physician-sponsored clinical trial open for enrollment and dosing patients for the treatment of brain tumors and a second physician-sponsored Phase 1 trial for the potential treatment of pediatric brain tumors has begun recruitment.

WP1220 is an analog of WP1066 for which Polish authorities approved the Company's Clinical Trial Application (CTA) in 2019 for a Phase 1 "proof-of-concept" clinical trial to study the topical treatment of CTCL. This trial was completed and the Company believes it demonstrated sufficient efficacy to justify a Phase 2 trial, which the Company expects to prepare for in the near future.

WP1066 along with another analog, WP1732, are being evaluated for the potential treatment of AML, pancreatic and other cancers. MBI has begun pre-clinical work that it expects to generate sufficient data for an IND for an intravenous formulation of one of its STAT3 inhibitors, which filing is expected to be submitted in 2021.

WP1122 and WP1234 are being evaluated for their potential to treat brain tumors and pancreatic cancer via their ability to inhibit glycolysis. The Company has begun preclinical work supporting WP1122 as a treatment for cancers and some viruses, including the Coronavirus which the Company believes may support an IND or its equivalent.

Clinical Trials - The Company has concluded the initial Phase 1 portion of its Phase 1/2 trial in the US due to the FDA’s requirement to set the initial dose level relatively low in comparison with previous Annamycin clinical trials. Additionally, the Company believes that patient recruitment for its clinical trial in Poland will continue to be more successful than in the US due to a comparatively lower number of competitive clinical trials and the protocol there being approved to start at a significantly higher dose than in the US with fewer enrollment screening limitations. This trial is in its fifth cohort in the dose ranging Phase 1 portion of the trial. In September 2018, the physician sponsored WP1066 Phase I clinical trial for the treatment of glioblastoma and melanoma metastasized to the brain, which opened for recruitment in July 2018, began treating patients. In April 2020, a second Phase 1 trial for another physician-sponsored clinical trial for the potential treatment of pediatric brain tumors began recruitment of patients. In August 2019, the Company completed its proof-of-concept Phase 1 clinical trial in Poland to study WP1220, a part of the WP1066 portfolio, for the treatment of CTCL. This trial demonstrated the safety of WP1220 and also demonstrated, the Company believes, initial efficacy sufficient for a Phase 2 trial, which the Company expects to prepare for in the near future.

Licenses - The Company has been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all of MBI's drug technologies, as these intellectual property rights are owned in part or entirely by MD Anderson. The Annamycin drug substance is no longer covered by any existing patent protection, however, the Company filed new patent applications in July 2019 for formulation, synthetic process and reconstitution related to MBI's Annamycin drug product candidate, although there is no assurance that the Company will be successful in obtaining such patent protection. Such technology is also licensed from MD Anderson. Independently from potential patent protection, MBI has received Orphan Drug designation (ODD) from the FDA for Annamycin for the treatment of AMLsoft tissue sarcoma (STS) lung metastases and for WP1066the Company expects to commence this study in the US in the second half of 2021. Based on a recently announced reimbursement grant awarded in Poland, MBI expects a second Phase 1b/2 clinical trial of Annamycin in STS lung metastases to be primarily investigator-funded in Europe.

ODD AML in Europe, by seeking approval for its own clinical trial and a second, similar grant funded trial through its sublicensee, WPD Pharmaceuticals in Poland. The Company is also working with regulatory authorities in the United Kingdom (UK) to initiate a Phase 1 clinical trial of WP1122 in healthy volunteers with the intent to progress to COVID-19 patients either there or in locations where the prevalence of COVID-19 will adequately support recruitment. The Company intends to internally fund the initial trials of WP1122 but may provide tax and other benefits during product development, andseek external funding opportunities if either productactivity is approved, may lead to a grant of seven-year market exclusivity. Under that exclusivity, which runs fromseen in COVID-19 patients. Additionally, the date of the approval of theCompany is pursuing filing an Investigative New Drug Application (NDA)application (IND) in the US the FDA generally (there are important exceptions) could not approve another product containing the same drug for the designated indication. The Company also intends to apply for similar status in the European Union (EU) where market exclusivity could extend to 10 years from the date of Marketing Authorization Application (MAA) approval. Separately, the FDA may also grant market exclusivity of 5 years for newly approved new chemical entities (which the Company believes Annamycin would be one), which would preclude approval of any other annamycin product, but there can be no assurance that such exclusivity will be granted. In April 2019, FDA approved the Company's request for Fast Track Designation for Annamycin for the treatment of relapsed or refractory AML. Fast Track Designation,certain cancers in 2021.

Reverse Stock Split - On January 29, 2021, the Company filed a Certificate of Amendment to the amended and restated certificate of incorporation with the Secretary of State and the State of Delaware to effect a reverse stock split of all the issued and outstanding shares of the Company's common stock at a ratio of 1 for 6. The accompanying consolidated financial statements and notes to the consolidated financial statements gives retroactive effect to the reverse stock split for all periods presented. Certain amounts in the financial statements, the notes thereto, and elsewhere in the Form 10-Q may be slightly different than previously reported due to rounding up of fractional shares as a result of the reverse stock split.

Basis of Presentation – Unaudited Interim Condensed Consolidated Financial Information - The accompanying unaudited interim condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the US (U.S. GAAP) for financial information, and in accordance with the rules and regulations of the US Securities and Exchange Commission (SEC) with respect to Form 10-Q10-Q and Article 8 of Regulation S-X.S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements furnished reflect all adjustments (consisting of normal recurring adjustments), which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These interim condensed unaudited consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of December 31, 2020 and December 31, 2019 and December 31, 2018 and notes thereto contained in the Form 10-K10-K filed with the SEC on March 19, 2020.

Significant Accounting Policies - The Company's significant accounting policies are described in Note 2,Basis of Presentation, principles of consolidation and significant accounting policies, to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. There have been no material changes to the significant accounting policies during the three months ended March 31, 2021, other than those noted below.

Use of Estimates - The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of financial statements. Estimates are used in the following areas, among others: fair value estimates on intangible assets, warrants, and stock-based compensation expense, as well as accrued expenses and taxes.


Going Concern

Liquidity and Financial Condition - These condensed consolidated financial statements have been prepared on a going concern basis, which assumes The Company is an early stage and emerging growth company (EGC) and has not generated any revenues to date. As such, the Company will continueis subject to realize its assets and discharge its liabilities in the normal course of business. The continuationall of the Company as a going concern is dependent upon the ability of the Company to obtain necessary equity financing to continue operationsrisks associated with early stage and the attainment of profitable operations. As of March 31, 2020,emerging growth companies. Since inception, the Company has incurred losses and negative cash flows from operating activities. For the three months ended March 31, 2021 and 2020, the Company incurred net losses of $4.4 million and $1.2 million, respectively, and had net cash flows used in operating activities of $3.6 million and $4.3 million, respectively. At March 31, 2021, the Company had an accumulated deficit of $40.8$61.4 million since inception and had not yet generated any revenue from operations. Additionally, management anticipates thatcash and cash equivalents of $86.3 million. The Company expects its cash on hand as of March 31, 2020, is2021 will be sufficient to fund its plannedthe Company's operations into but not beyond the near term. These factors raise substantial doubt regardingSuch projections are subject to changes in the Company’s abilityinternally funded preclinical and clinical activities, including unplanned preclinical and clinical activity. The Company does not expect to experience positive cash flows from operating activities in the near future and anticipates incurring operating losses for the next few years as it supports the development of its core technologies to the point of generating revenue, most likely via outlicensing, and continues to invest in research and development for additional applications of the Company's core technologies and potentially increase its pipeline of drug candidates. The Company anticipates incurring operating losses for the next several years. If the Company needs to raise additional capital in order to continue as a going concern. These unaudited condensed consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. Management cannot be certain that such events or a combination thereof can be achieved.

Cash and Cash Equivalents - Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company considers all highly liquidmaintains cash accounts with original maturities of three months or lessprincipally at the date of acquisition to be cash equivalents. Periodicallyone financial institution in the ordinary course of business,US, which at times, may exceed the Federal Deposit Insurance Corporation’s limit. The Company may carryhas not experienced any losses from cash balances at financial institutions in excess of the Federally insured limits of $250,000.


Prepaid Expenses and Other Current Assets - Prepaid expenses and other current assets consistinsurance limit. The Company’s management does not believe the Company is exposed to significant credit risk at this time due to the financial condition of the following (in thousands):

Vendor prepayments at March 31, 2020 and December 31, 2019, respectively, includes approximately $1.1 million and $1.5 million, for the expansion of Annamycin production commitments on a commercial scale currently expected to be delivered in 2020 for use in clinical trials.

Intangible Assets - Intangible assets with finite lives are amortized using the straight-line method over their estimated period of benefit. Acquired intangible assets identified as in-process research and development (IPR&D) assets, are considered indefinite lived until the completion or abandonment of the associated research and development efforts. If the associated research and development effortfinancial institution where its cash is abandoned, the related IPR&D assets will be written-off and the Company will record a noncash impairment loss on its statements of operations. For those compounds that reach commercialization, the IPR&D assets will be amortized over their estimated useful lives. The Company evaluates the recoverability of intangible assets periodically and take into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. NaN impairments of intangible assets have been identified during any of the periods presented. Intangible assets are tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach.

Property and Equipment, net - Leasehold improvements, furniture, equipment and software are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. Accumulated depreciation on property and equipment was $0.3 million at March 31, 2020, and December 31, 2019, respectively.

Operating Lease Right-of-Use Asset - The Company determines if an arrangement is a lease at contract inception or during modifications or renewal of an existing lease. Operating lease assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. The lease payments used to determine the Company's operating lease assets may include lease incentives, stated rent increases and escalation clauses linked to rates of inflation when determinable and are recognized in the Company's operating lease assets in the Company's condensed consolidated balance sheet. The Company has elected the practical expedient and does not separate lease components from nonlease components for its leases. The Company's operating leases are reflected in operating lease right-of-use asset (ROU), accrued expenses and other current liabilities, and operating lease liability - long-term in the Company's condensed consolidated balance sheets. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of 12 months or less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease. Refer to Note 7 - Commitments and Contingencies - Lease Obligations Payable for additional information related to the Company’s operating leases.

Fair Value of Financial Instruments - The Company's financial instruments consist primarily of non-trade receivables, account payables,accounts payable, accrued expenses and its warrant liability. The carrying amount of non-trade receivables, accounts payables,payable, and accrued expenses approximates their fair value because of the short-term maturity of such.

The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-levelthree-level fair value hierarchy in accordance with U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1)1) and lowest priority to unobservable inputs (Level 3)3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:

Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.

Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 – Unobservable inputs for the asset or liability.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of warrant liability discussed in Note 4.

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. For purposes of this calculation, options to purchase common stock, restricted stock units subject to vesting and warrants to purchase common stock are considered to be common stock equivalents. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock

equivalents, because their inclusion would be antidilutive. For the three months ended March 31, 2020 2021 and 2019,2020, approximately 18.43.8 million and approximately 6.73.1 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to their antidilutive effect.

Stock-based Compensation - Stock-based compensation expense includes the estimated fair value of equity awards vested or expected to vest during the reporting period. The Company accounts for its stock-based compensation awards in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic (ASC) 718, Compensation—Stock Compensation (ASC 718). ASC 718 requires all stock-based payments to employees, including grants of employee stock options, restricted stock units, and modifications to existing stock options, to be recognized in the consolidated statements of operations based on their fair values. The grant date fair value of stock options is determined using the Black-Scholes option pricing model and the grant date fair value of restricted stock awards is determined using the closing price of the Company’s common stock on the date of grant. The awards are subject to service vesting conditions. Compensation expense related to awards to employees and directors with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term, net of forfeitures which are recognized as they occur. Compensation expense related to awards to non-employees with service-based vesting conditions is recognized based on the then-current fair value at each financial reporting date prior to the measurement date over the associated service period of the award, which is generally the vesting term. Effective January 1, 2020, the Company began using the volatility of its own stock since it now has sufficient historic data in its stock price.

Subsequent Events - The Company’s management reviewed all material events through the date these unaudited condensed consolidated financial statements were issued for subsequent events disclosure consideration, see other notes and specifically Note 8 - Subsequent Events.

Recent Accounting Pronouncements

In August 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-13, Fair Value Measurement (Topic 820) (ASU 2018-13). ASU 2018-13 modifies the disclosure requirements on fair value measurements in ASC Topic 820, Fair Value Measurement, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company's adoption of this pronouncement effective January 1, 2020, did not have a material impact on the Company's condensed consolidated financial statements.


In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) (ASU 2019-12)2020-06).

Liability Classified Warrants


The Company uses the Black-Scholes option pricing model (BSM) to determine the fair value of its warrants at the date of issue and outstanding at each reporting date.


The risk-free interest rate assumption is based upon observed interest rates on zero coupon US Treasury bonds linearly interpolated to obtain a maturity period commensurate with the term of the warrants.

Estimated volatility is a measure of the amount by which the Company's stock price is expected to fluctuate each year during the expected life of the warrants. Beginning in 2020, only the volatility of the Company's own stock is used in the BSM as it now has sufficient historic data in its stock price. In 2019, the Company used the volatility of its own stock blended with the volatility of peer entities due to the lack of sufficient historical data of our stock price.

The assumptions used in determining the fair value of the Company’s outstanding liability classified warrants are as follows:

6. Income Taxes

Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company does not expect to pay any significant federal, state, or foreign income taxes in 20202021 as a result of the losses recorded during the three months ended March 31, 20202021 and the additional losses expected for the remainder of 20202021 and cumulative net operating loss carryforwards. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all of the benefits of deferred tax assets will not be realized. As a result, as of March 31, 2020,2021, the Company maintained a full valuation allowance for all deferred tax assets.

10

The Company recorded 0 income tax provision for the three months ended March 31, 2020 2021 and 2019,2020, respectively. The effective tax rate for the three months ended March 31, 2020 2021 and 20192020 is 0%. The income tax rates vary from the federal and state statutory rates primarily due to the change in fair value of the stock warrants and valuation allowances on the Company’s deferred tax assets. The Company estimates its annual effective tax rate at the end of each quarterly period. Jurisdictions with a projected loss for the year where no0 tax benefit can be recognized due to the valuation allowance could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.


On March 27, 2020, Congress enacted the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) to provide certain relief as a result of the COVID-19 pandemic. The CARES Act, among other things, includes provisions relating to net operating loss carry back periods, alternative minimum tax credit refunds, and modification to the net interest deduction limitations. The CARES Act did not have a material impact on our condensed consolidated financial statements for the three months ended March 31, 2020. We continue to monitor any effects that may result from the CARES Act.

As of March 31, 2021, the weighted average remaining lease term for operating leases is 2.2 years, and the weighted average discount rate is 9.6%. The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses an incremental borrowing rate based on a peer analysis using information available at the commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

Licenses


MD Anderson - Total expenses related to the Company's license agreements with MD Anderson were $61,000$38,000 and $60,000$61,000 for the three months ended March 31, 2020 2021 and 2019,2020, respectively.


HPI - On March 16, 2020, the Company entered into 2two agreements with a related party, Houston Pharmaceuticals, Inc.(HPI). The first agreement, which has a term of two years, continues a prior consulting arrangement with HPI on the Company's licensed molecules and requires payments for $43,500 per quarter to HPI. The second agreement, which can be cancelled with sixty days' notice by either party, allows the Company's employees access to laboratory equipment owned by HPI for a payment of $15,000 per quarter to HPI. Total expenses related to the Company's agreements with HPI were $207,500$59,000 and $75,000$108,500 for the three months ended March 31, 2020 2021 and 2019,2020, respectively.

Overview


Moleculin Biotech, Inc., a Delaware corporation, is

We are a clinical stage pharmaceutical company focused on the treatment of highly resistant cancers and viruses. We have three core technologies, all of which are based substantially on discoveries made at M.D. Anderson Cancer Center (MD Anderson). We haveThese three core technologies are Annamycin, the WP1066 Portfolio, and the WP1122 Portfolio and include a total of six drug candidates, that are activethree of which have now shown human activity in clinical trials. In 2019, those three drug candidates were active in four clinical trials in the US and Europe with a fifth that began recruiting patients in April 2020. Of these five clinical trials, two are primarily externally funded. For two of our internally funded trials, we successfully concluded the Phase 1 portion recently and are preparing to potentially move into Phase 2 trials. We anticipate laying the groundwork in 2020 for two additional Phase 1 trials expected to begin in 2021 sponsored by us and two other Phase 1 trials we expect to be externally sponsored.


We recently announced a collaboration with a major Texas university institution to evaluate our drug candidate, WP1122, and now this has been followed by collaborations with additional entities who bring additional expertise in developing potential treatments for diseases like COVID-19. The preclinical work to evaluate WP1122's potential against the Coronavirus is similar to preclinical work originally planned for 2020 to develop against cancer indications, supporting a cancer-related Investigational New Drug (IND) application for clinical trials in 2021.

18


Based on our positive clinical activity thus far, we have narrowed our development focus to our nearest term opportunities, including Annamycin, WP1222 and WP1220, while relying on external funding for other projects. In addition, the opportunity related to COVID-19 has pushed the development of WP1122 to the forefront. Notwithstanding the emphasis on WP1122, we believe our overall narrowing of focus will allow us to reduce our cash needs until we reach a significant value inflection point, although we will continue to require additional external capital during this period. In addition, institutional support for our technologies has increased and we believe such support may provide outside funding to help reduce future cash needs. Such expectations assume some form of government funding for WP1122 if it is successful in bridging from preclinical to clinical activity in 2020, although we have no commitments at this time for such funding and can provide no assurances that such funding can be obtained.

Of our three clinical stage drug candidates, Annamycin is being studied for the treatment of relapsed or refractory acute myeloid leukemia (“AML”) and cancers metastasized to the lungs. WP1066, an Immune/Transcription Modulator (p-STAT3 inhibitor) is intended to target a wide range of tumors, including brain tumors and pancreatic cancer. We began and completed a "proof-of-concept" Phase 1 clinical trial in 2019 in Poland for a third drug, WP1220 (a molecule similar to WP1066), for the topical treatment of cutaneous T-cell lymphoma (CTCL) and we are planning to expand development of this drug into a Moleculin Phase 2 trial. We are also engaged in preclinical development of additional drug candidates, including additional Immune/Transcription Modulators, as well as Metabolism/Glycosylation Inhibitors.

Three Core Technologies

We consider Annamycin to be a "next generation" anthracycline, unlike any currently approved anthracyclines, as it is designed to avoid multidrug resistance mechanisms with little to no cardiotoxicity (two problems common to(the efficacy of all currently approved anthracyclines)anthracyclines is limited by both multidrug resistance and cardiotoxicity). We recently received an independent expert cardiology assessment confirming the absence of cardiotoxicity in the first 14 patients treated with Annamycin in both our US and European Phase 1 clinical trials, validating Annamycin's lack of cardiotoxicity. Annamycin is currently in one Phase 1/2 clinical trial in Europe with the Phase 1 portion of another Phase 1/2 AML trial recently concluding in the US. Upon receipt of further data from the European Phase 1 trial, we plan to seek agreement with the FDA for accelerated approval of Annamycin based on a pivotal Phase 2 AML trial sponsored by us, although there is no assurance that the FDA will agree with our proposal.


In 2019, preclinical work on Annamycin demonstrated activity against certain cancers metastasized to the lungs. With this new data, we are planning to start a Moleculin-sponsored US Phase 1 trial at MD Anderson for the treatment of cancer metastasized to the lungs with Annamycin, although no assurances can be given that such trial will begin.

WP1066 is one of several Immune/Transcription Modulators, designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory TCellsT-Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3 (phosphorylated signal transducer and activator of transcription 3), c-Myc (a cellular signal transducer named after a homologous avian virus called Myelocytomatosis) and HIF-1α (hypoxia inducible factor 1α). These transcription factors are widely sought targets that are believed to contribute to an increase in cell survival and proliferation, and the angiogenesis (coopting vasculature for blood supply), invasion, metastasis and inflammation associated with tumors. They may also play a role in the inability of immune checkpoint inhibitors to affect more resistant tumors. WP1220 is a close analog to WP1066 that we have developed as a potential topical therapy for skin-related diseases.

Our third core technology is currently in a US physician-sponsored Phase 1 trial for the treatment of glioblastoma ("GBM") and another institutionally sponsored Phase 1 trial has begun recruiting for the treatment of pediatric brain tumors. Another physician-sponsored Phase 1 trial is being considered for the treatment of GBM with WP1066 in combination with radiation, although no assurances can be given that such trial will begin.


We are also developingcentered on new compounds designed to exploittarget the potential uses of inhibitorsroles of glycolysis such as 2-Deoxy-D-glucoseand glycosylation in both cancer and viral diseases. As an example, 2-deoxy-D-glucose (2-DG), which we believe may provide an opportunity to limit is a glucose decoy that is capable of inhibiting glycolysis, thereby cutting off the energy available to tumorsprimary fuel supply for both cancer cells and virus host-cellsviral host cells by taking advantage of their high level of dependence on glucose in comparison to healthy cells. A key drawback toIn addition, 2-DG is capable of altering glycosylation, a process by which, when coopted by tumors, cancer cells are believed to evade the body’s immune response. In the case of viruses like SARS-CoV-2 (the virus responsible for COVID-19), glycosylation forms the glycoprotein spikes surrounding the coronavirus that give it its lackname and enable both evasion of drug-like properties, includingthe immune response and the ability to infect new host cells. One of the limitations of 2-DG, however, is how rapidly it is metabolized, resulting in a short circulation time and poorlimited tissue/organ distribution characteristics. Our lead Metabolism/Glycosylation Inhibitor, WP1122, is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. Recent published research has identified that 2-DG has antiviral potential against SARS-CoV-2 in vitro and, based on publicly available information, a recently completed Phase 2 clinical trial by an unrelated company in India has reported efficacy in COVID-19 patients, resulting in the Emergency Use Authorization of 2-DG by the Drugs Controller General of India. New research also points to the potential for 2-DG to be capable of enhancing the usefulness of checkpoint inhibitors and also its potential against viruses like the Coronavirus.inhibitors. Considering that WP1122 generally outperforms 2-DG lacks sufficient drug-like properties to be practicalalone in a clinical setting,both in vitro and in vivo tumor models and in viral in vitro models, we believe WP1122 has the potentialopportunity to become an important drug either as a single agent or to potentiate existing therapies, including checkpoint inhibitorsinhibitors. We are also engaged in preclinical development of additional antimetabolites (WP1096 and antiviral treatments. In March 2020, we entered into agreements with several outside research laboratories that will conduct research on WP1122 for antiviral properties against a range of viruses, including Coronavirus. We have also added experts to our Science Advisory Board to support our anti-viral efforts.

The FDA has created a special emergency program for possible therapies, the Coronavirus Treatment Acceleration Program (CTAP). FDA comments that it uses every available method to move new treatments to patients as quickly as possible, while at the same time finding out whether they are helpful or harmful. As cited by the FDA on their CTAP website:

Completed review of single patient expanded access requests around-the-clock – and generally within 3 hours.
Worked closely with applicants and other regulatory agencies to expedite quality assessments for products to treat COVID-19 patients and to transfer manufacturing to alternative or new sites to avoid supply disruption.”

Comparing the intended turnaround times of the FDA above to its normal 60 day turnaround time for a pre-IND meeting request and 30 days for an IND review, these are expedited timelines. We plan on utilizing these aspects, which may shorten the various FDA review periods in connection with a potential IND for WP1122, although we can provide no assurance that the FDA will shorten its review period or eventually approve any IND application.

Recent Business Developments

Below are recent business developments.

Annamycin

Approved to Accelerate European Clinical Trial

We announced on April 28, 2020, that we are now authorized by the Polish Department of Registration of Medicinal Products known as URPL to accelerate theour internally funded Phase 1 dose escalation portionclinical trials have concluded. The US trial for Annamycin in acute myeloid leukemia (AML) successfully met its safety endpoint, and the trial for WP1220 in cutaneous T-cell lymphoma (CTCL) demonstrated an objective response rate of our45% and a clinical benefit rate of 100%. An additional Phase 1/2 clinical trial of Annamycin in AML is also internally funded and is currently ongoing. In 2021, we anticipate the initiation of four or more new clinical trials in addition to the three trials continuing from 2020.

Below we use certain terms to describe our clinical trials. By "internally funded” we mean that the primary costs of the preclinical activity and clinical trials are funded by us. “Externally funded” drug candidates include those for which preclinical work is funded and performed by external collaborators and for which clinical trials are physician sponsored. For externally funded research, any grant funds that support such preclinical work or clinical trials and most of the associated expenses are not reflected in our financial statements. However, the costs of drug product and other minor supporting activities that we provide for externally funded preclinical activities and clinical trials are included in our financial statements.

Recently reported data from our sponsored research demonstrates that in AML mouse models, the combination of Annamycin with Ara-C (a chemotherapy drug commonly used in AML patients) has a synergistic effect, suggesting that this combination may be more beneficial for AML patients than Annamycin as a single agent. Accordingly, we plan to begin a Phase 1/2 clinical trial of Annamycin in combination with Ara-C for the treatment of AML. The URPL has allowed an amendment to the AnnamycinAML in Europe, by seeking approval for our own internally funded clinical trial protocol, which among other things, includes an increase in the dose escalation increment between cohorts from 30 mg/m2Europe and a second, similar trial through our sublicensee, WPD Pharmaceuticals, in Poland. Furthermore, we received U.S. Food and Drug Administration (FDA) clearance in late 2020 to 60 mg/m2. The clinical trial is currently recruiting for the 240 mg/m2 cohort, so this amendment allows the next cohort to increase to 300 mg/m2, assuming all requirements for safety are metproceed with the 240 mg/m2 cohort.


Positive Safety Data in EU AML Trial

On April 2, 2020, we announced that we completed the latest (210 mg/m2) cohort in our European open label, single arma Phase 1/1b/2 clinical trial of Annamycin for the treatment of relapsedsoft tissue sarcoma (STS) lung metastases and we are preparing to begin this internally funded trial in the US in the third quarter of 2021. Additionally, we expect in 2021 a second Phase 1b/2 clinical trial of Annamycin in sarcoma lung metastases to be primarily investigator-funded in Europe.

WP1066 is currently in two US physician-sponsored Phase 1 trials, one at MD Anderson for the treatment of glioblastoma (GBM) in adults and another at Emory University for the treatment of pediatric brain tumors (including DIPG and medulloblastoma). We began and completed a "proof-of-concept" Phase 1 clinical trial in 2020 in Poland for a third drug, WP1220 (a molecule in the WP1066 portfolio), for the topical treatment of cutaneous T-cell lymphoma (CTCL). We are actively seeking collaboration with a strategic partner in the near term for external funding for the continued development of WP1220 in a Phase 2 clinical trial as a topical therapy for CTCL, and based on the pace of current discussions, we do not anticipate this trial to begin this year. If we are not successful in this outreach, we may choose to use internal funds to generate additional human data to facilitate such outreach efforts.

Finally, we are also in discussions with regulatory authorities in the United Kingdom (UK) to initiate a Phase 1 clinical trial of WP1122 in healthy volunteers with the intent to progress to COVID-19 patients either there or refractory AML. Ain locations where the prevalence of COVID-19 will adequately support recruitment. We intend to internally fund the initial trials of WP1122 but may seek external funding opportunities. Additionally, we are planning to file an IND in the US for the treatment of certain cancers with WP1122.

In summary, we had five clinical trials underway or concluded in 2020 and we now expect up to seven or more clinical trials to be underway or approved in 2021, including externally funded trials.

Update on Clinical Trials and Licensing

Annamycin

Annamycin is currently in one Phase 1/2 clinical trial in Europe, and the Phase 1 portion of another Phase 1/2 AML trial in the US has been concluded, subject to final database lock and closure, which should occur in the third quarter of 2021. 

The trial in Poland is in its fifth cohort, where patients are being treated at 240 mg/m2. Patient 2 in this cohort experienced certain elevated liver enzymes (AST and ALT), which under the current protocol, are considered a dose limiting toxicity (DLT). In this instance, the DLT was secondarily related to concomitant medication not being withheld. Although that DLT resolved, in accordance with the trial protocol, the cohort was expanded and has now enrolled a total of 19five patients. In March 2021, patient 4 in this cohort experienced a similar DLT, which also resolved. Although treatment was discontinued for Patients 2 and 4, a total of three patients in this cohort received the full dose of Annamycin without any DLTs and, based on preliminary data, all three responded to treatment, with one relapsed patient experiencing a complete response (CR), a refractory patient experiencing a partial response (PR) and another relapsed patient completely clearing circulating blasts. With this preliminary data, 40% of the patients being treated at 240 mg/m2 experienced clinical benefit. Combining these results with prior cohorts in Poland and with the cohorts in the US trial, six of seventeen relapsed AML patients or 35% experienced clinical benefit (CR, CRi, PR, or Bridge-To-Transplant). One refractory patient in the Poland trial experienced a PR.

Although the elevated liver enzymes described above meet the test of a “Dose Limiting Toxicity” per the clinical trial protocol, our medical advisors have determined that these instances were transient and self-limited with no evidence of serious sequalae (related longer-term negative effects) and, therefore, should not be considered DLTs in future patients unless these elevated enzyme levels do not return to near baseline (baseline or less than or equal to grade 1) within a reasonable time or if there is other evidence of serious sequalae. Based on this new data, we are planning to amend the protocol for this trial in Poland to change the DLT criteria as it relates to transient grade 3 elevations to allow us to dose three additional patients in the 240 mg/m2 cohort. If no DLT is experienced with these next three patients, we will escalate dosing in new cohorts by 30 mg/m2 instead of the 60 mg/m2 previously planned, and with a de-escalation of 15 mg/m2 at the DLT dose if future patients experience a DLT. We cannot provide any assurance that such an amendment will be approved.

Additionally, our sublicense partner, WPD Pharmaceuticals Sp.z o.o. (WPD), recently announced that it was conditionally awarded a reimbursement grant of approximately $6.7 million (20.4 million PLN) from the Polish National Center for Research and Development (“NCRD”), for the development of Annamycin. The funds will be used for the continued development of Annamycin, including a clinical trial of Annamycin in combination with Ara-C for which this grant is expected to cover the reimbursement of about 60% of planned costs. WPD is a sub-licensee of certain technologies from us in 29 countries in Europe and Asia. We expect that this trial will begin in 2021 but since this is an externally funded trial, we cannot provide any assurance regarding actual timing.

Regarding our planned US clinical trial of Annamycin for the treatment of STS lung metastases, we executed a clinical trial agreement with with Sarcoma Oncology Research Center, an institution in Santa Monica, CA to be the first clinical site. We expect this trial to begin in the third quarter of 2021.

Earlier in 2021, we announced that the Agencja Badań Medycznych (The Medical Research Agency) a Polish state agency responsible for development of scientific research in the field of medical and health sciences, awarded a grant equivalent to $1.5 million to the Maria Sklodowska-Curie National Research Institute to fund a Phase 1b/2 clinical trial of Annamycin for the treatment of STS lung metastases. The grant-funded clinical trial will be led by Prof. Piotr Rutkowski, MD, PhD, Head of Department of Soft Tissue/Bone Sarcoma and Melanoma at the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland. Prof. Piotr Rutkowski will be assisted, in part, by WPD who will provide support in preparation for and conduct of the clinical trial, which is expected to begin this year. As a part of the collaboration between Moleculin and Prof. Rutkowski, Moleculin will be supplying the drug product and other ancillary services necessary for the clinical trial, but Moleculin will not participate in conducting the clinical trial. This trial is independent from and will be in addition to the US clinical trial Moleculin is planning to conduct with Annamycin in STS lung metastases.

WP1066

The clinical trial of WP1066 for the treatment of adult brain tumors at MD Anderson has completed the fourth cohort at 8mg/kg in the dose escalation phase. In the first quarter of 2021, we were notified that the physician sponsoring this trial is leaving MD Anderson. As a result, MD Anderson has notified us that they will be closing this trial. Several additional institutions have expressed an interest in sponsoring similar research on WP1066 in brain tumors, so to help ensure the potential continuation of this important research, regardless of the sponsoring institution, we have requested the IND for this trial to be transferred into our name with the FDA, although we can provide no assurance as to when, or if, this transfer will be completed. While we are working to continue this research in additional physician-sponsored trials, we expect that continued research on WP1066 in adult GBM will be temporarily delayed in 2021.

Three patients have now been treated in the USsecond cohort of the Phase 1 dose escalation portion of physician-sponsored clinical trial at Emory University for the treatment of pediatric brain tumors with WP1066 at the dose level of 6mg/kg and Europe, and all results continue to show Annamycinthis dose has been deemed to be safe, and, especially, all have shown Annamycinsafe. Recruitment will now begin for the third cohort with dosing at 12 mg/kg.

WP1122

Based on previously announced data demonstrating the antiviral potential of our lead antimetabolite molecule, WP1122, we intend to be free of cardiotoxicity. Of those, 10 have been treated at or abovetest the FDA lifetime maximum anthracycline exposure.


WP1122

Head of NIAID Antiviral Drug Discovery and Development Center Joins COVID-19 Drug Development Team

On April 22, 2020, we announced that we have retained Dr. Richard Whitley to our Science Advisory Board to guide our development strategy for WP1122drug candidate for the potential treatment of COVID-19. Although we have previously disclosed that antiviral clinical trials in the US will be dependent upon demonstrating efficacy in an appropriate COVID-19 animal model, we recently engaged in discussions with the Medicines and other viral diseases. Richard Whitley, M.D., is a Distinguished Professor of Pediatrics, Professor of Microbiology, Medicine and Neurosurgery; Loeb Eminent Scholar ChairHealthcare Products Regulatory Agency (MHRA) in Pediatrics; Co-Director, Division of Pediatric Infectious Diseases; Vice-Chair, Department of Pediatrics; Senior Scientist, Department of Gene Therapy; Scientist, Cancer Research and Training Center; Faculty, Gene Therapy Center; Associate Directorthe United Kingdom (UK) regarding the potential for Drug Discovery and Development and Senior Leader, Pediatric Oncology Program, O'Neal Comprehensive Cancer Center at the University of Alabama at Birmingham (UAB); and Co-Founder and Co-Director, Alabama Drug Discovery Alliance.

Dr. Whitley is responsible for the National Institute of Allergy and Infectious Diseases Collaborative Antiviral Study Group whose role is to performbeginning clinical trials of antiviral therapies directed against medically important viral diseasesWP1122 without the need for additional preclinical animal efficacy models. Based on our initial discussions with the MHRA, we believe that a COVID-19 animal model will not be required in order to submit a clinical trial application (CTA) for a Phase 1 clinical trial beginning with healthy volunteers in that country, although no final determination has been made by the MHRA. Based on this feedback, we intend to proceed with the submission of children and adults including viruses considered as threats to human health. He participates in numerous Data Safety and Monitoring Boardsa CTA for ongoinga Phase 1 clinical studies. He is a past President of the Infectious Diseases Society of America and received the UAB President's Medal in 2007. In 2013, he was named as the inaugural recipient of the Distinguished Clinical Research Scholar and Educator in Residence at the NIH Clinical Center.

Agreement with ImQuest Biosciences to Expand Coronavirus Testing

We announced on April 20, 2020, that we entered into an agreement with ImQuest Biosciences to expand in vitro and in vivo testingtrial of WP1122 in the UK.

The preclinical work to evaluate molecules within the WP1122 portfolio of antimetabolites (which include molecules capable of inhibiting glycolysis and altering glycosylation) for viral indications is mostly similar to the preclinical work we originally planned as part of developing WP1122 for cancer indications. Accordingly, we believe the preclinical work we have completed for WP1122 will also support an IND application or its equivalent in other countries for cancer-related clinical trials. We continue to plan to submit such an IND in the US in 2021.

COVID-19 Impact on Clinical Trials

The spread of COVID-19 has caused significant volatility in US and international markets, including Poland, where we conduct some of our leadclinical trials, and Italy, where our drug candidatesupply is produced. There has been limited interruption of our drug supply, and most Polish clinics where we are conducting trials are limiting access for monitoring activities, which could delay our ability to collect data and authorize new patient recruitment. Additionally, we believe COVID-19 has materially slowed the ability of approved sites to recruit patients for our trials. This could worsen or be alleviated at any time. Furthermore, there is significant uncertainty around the breadth and duration of business disruptions related to COVID-19, as well as its impact on the US and international economies and, as such, we are unable to determine if it will have a material impact to our operations. Recently, we continue to experience a limited increase in activity with regard to recruitment of new patients in Poland. Additionally, we believe that the potential for impact to our supply chain due to COVID-19 has been reduced as vaccine production normalizes throughout the industry. Considering current worldwide trends with respect to COVID-19, we cannot determine whether COVID-19 will materially impact recruitment for current or future trials.

Licensing

We are currently in discussions with MD Anderson regarding amendments to existing licenses and new licenses related to Annamycin and WP1122.

IQVIA to Manage Potential COVID-19 Clinical Trial

On April 15, 2020,6, 2021, we announced that Dr. Dominique Scholsthe engagement of the Rega Institute has joined the Moleculin development team asIQVIA Biotech, a consultant. The Rega Institute of Medical Research, Belgium, is one of the premier medicalcontract research institutes in Europe. Dr. Dominique Schols is Professor and Head of the Laboratory of Virology and Chemotherapy, Department of Microbiology and Immunology and Transplantation of the University of Leuven, Belgium.


Independent Research Finds Active Compound in WP1122 Reduces Coronavirus Replication in Vitro by 100%

On April 8, 2020, we announced that independent research found 2-DGorganization (CRO) to reduce replication of SARS-CoV-2, the virus that causes COVID-19, by 100% in in vitro testing. This cited research is a preprint, which is a preliminary report that has not undergone peer review. Moleculin's drug candidate, WP1122, is referredmanage our efforts to as a "prodrug" of 2-DG whereby chemical elements are added to 2-DG to improve its delivery in vivo. Once administered, these added elements are removed by normal metabolic processes and what remains is 2-DG. As a result, 2-DG is the active compound in WP1122. In chemical terms, it is referred to as the active "moiety" (subpart) of WP1122.

Patent Filing to Cover New Coronavirus Drug Candidate

We announced on March 20, 2020, that a new patent application has been filed covering the usebegin potential clinical trials of WP1122 and its analogs as therapies to limitfor the abilitytreatment of Coronavirus and other viruses to replicate. The patent application covers joint discoveries which came as a result of an ongoing sponsored research agreement.

SEC matters

On May 1, 2020, the SEC pursuant to Section 12(k) of the Securities Exchange Act of 1934, as amended, ordered the temporary suspension of trading in the securities of Moleculin because of questions regarding the accuracy and adequacy of information in the marketplace about Moleculin and its securities. Pursuant to the suspension order, the suspension commenced at 9:30 a.m. EDT on May 4, 2020 and terminates at 11:59 p.m. EDT on May 15, 2020. As of the date of this report, we have submitted a petition to terminate the suspension, but there is no assurance that we will be successful. We believe we will be able to demonstrate the accuracy and adequacy of our public disclosures, but the SEC may determine to extend the trading suspension until such time that it believes the information in the marketplace about us and our securities is accurate and adequate.

General and Administrative Expense. General and administrative expense was $1.8$1.9 million and $1.6$1.8 million for the three months ended March 31, 20202021 and 2019,2020, respectively. The increase of $0.2$0.1 million is mainly related to an increase in our insurance, which was mainly attributable to increased payroll costs for an additional finance employee, increased stock-based compensation expense for annual employee stock options, and increased costs for directors and officer's liability insurance.


offset by a similar decrease in travel expenses.

Gain from Change in Fair Value of Warrant Liability. We recorded a net gain of $1.6 million in the first quarter of 2021 as compared to a net gain of $3.8 million in the first quarter of 2020, as compared to a net gain of $0.5 million in the first quarter of 2019, for the change in fair value on revaluation of our warrant liability associated with our warrants issued in conjunction with our stock offerings. We are required to revalue our liability-classified warrants at the time of each warrant exercise, if applicable, and at the end of each reporting period and reflect in the statement of operations a gain or loss from the change in fair value of the warrant in the period in which the change occurred. We calculated the fair value of the warrants outstanding using the Black-Scholes model. A gain results principally from a decline in our share price during the period and a loss results principally from an increase in our share price.

Cash used in operating activities


Cash used in operations was $4.3$3.6 million forfor the three months ended March 31, 2020.2021. This $0.5$0.7 million increasedecrease over the prior year period of $3.8of $4.3 million was primarily due to:to an increase in accounts payable, which was slightly offset by: 1) payments for developing, manufacturing and testing drug product as we prepared for clinical trials; 2) an increase in R&D employee and contractor headcount and associated payroll costs; 3) an increase in paid sponsored research and related expenses; and 4) an increase in license fees. These are all a reflection of the ongoing clinical and pre-clinical activity and the associated increase in general and administrative support for our three core drug technologies.


Cash used in investing activities

Net cash used in investing activities was $2,000 for the three months ended March 31, 2020 compared to $15,000 for the three months ended March 31, 2019. The decrease relates to purchases in 2019 related to furniture and fixtures for our corporate apartment, as well as additional electronic equipment for employees and our corporate office.

Cash provided in financing activities


In February 2021, we completed an underwritten public offering of an aggregate of 14,273,684 shares of common stock at a public offering price of $4.75 per share. We granted the underwriters a 30-day option to purchase up to an additional 2,141,052 shares of common stock offered in the public offering. The offering closed on February 5, 2021 and gross proceeds of the offering were approximately $67.8 million, prior to deducting the underwriting discount and other offering expenses. On February 10, 2021, the underwriters of the public offering exercised in full their option to purchase an additional 2,141,052 shares of common stock at the public offering price of $4.75 per share, bringing total gross proceeds to approximately $78.0 million before underwriting discount.

In January 2021 we issued 468,684 shares for gross proceeds of $2.9 million using our At The Market Agreement with Oppenheimer & Co., Inc. We terminated the ATM Agreement on February 2, 2021. Additionally, during the first quarter of 2021, 10,000 shares were issued due to the exercise of warrants related to past public offerings. Gross proceeds received due to these exercises approximated $63,000.

In February 2020, we entered into subscription agreements with institutional investors to purchase of 7,500,0001,250,000 shares of our common stock and warrants to purchase 5,625,000937,501 shares of common stock at a combined public offering price of $0.80$4.80 per share and related warrant resulting in gross proceeds of $6.0 million. Each warrant has an exercise price of $1.05$6.30 per share and will bewere exercisable six months from the date of issuance and will expire five years from the date they arewere first exercisable.


During the three months ended March 2019, we completed an underwritten offering of 5,250,000 shares of our common stock and warrants to purchase 2,650,000 shares of common stock for net proceeds of $4.7 million after deducting the underwriting discount and estimated offering expenses and we sold 605,367 shares of our common stock to Lincoln Park Capital Fund, LLC for $0.9 million.

We believe that our existing cash and cash equivalents as of March 31, 2020 combined with the shares we sold in April 2020 through the At Market Issuance Sales Agreement2021 will be sufficient to fundmeet our planned operations intoprojected operating requirements, which include a forecasted increase over our current R&D rate of expenditures, through at least the first quarter of 2021, without the issuance of additional equity for cash. Any such issuances should extend the funding of our planned operations beyond the first quarter of 2021.year 2023. Such plansprojections are subject to our stock price, market conditions, changes in planned expenses depending onour internally funded preclinical and clinical enrollment progress,activities, including unplanned preclinical and clinical activity. We anticipate incurring operating losses for the use ofnext several years as we support the preclinical and clinical activities necessary to prepare our drug product or a combination thereof. Based on the Company's current assessment, the Company does not expect any material impact on its long-term development timeline and its liquidity duecandidates for successful out licensing, including our efforts to the worldwide spread of the COVID-19 virus.


We will not generate revenue from product sales unless and untilexpand our technologies. These factors raise uncertainties about our ability to fund operations in future years. If we successfully complete development of, obtain regulatory approval for and begin to commercialize one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital in order to fundcontinue to execute our future operations. Until such timebusiness plan, there is no assurance that additional financing will be available when needed or that we can generate substantial revenue from product sales, if ever, we expectwill be able to finance our operating activities through a combination of equity offerings and debt financings, and we may seekobtain financing on terms acceptable to us.

Critical Accounting Policies and Significant Judgments and Estimates

The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
We believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.
Research and Development Costs
We record accrued expenses for estimated costs of our research and development activities conducted by third-party service providers, which include the conduct of pre-clinical and clinical studies and preparation for clinical trials and contract manufacturing activities. We record the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced, and we include these costs in accrued liabilities in the balance sheets and within research and development expense in the statements of operations. These costs are a significant component of our research and development expenses. We record accrued expenses for these costs based on the estimated amount of work completed and in accordance with agreements established with these third parties.
We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As actual costs become known, we adjust our accrued estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed may vary from our estimates and could result in us reporting amounts that are too high or too low in any particular period. Our accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from clinical research organizations and other third-party service providers. To date, there

There have been no material differenceschanges to our critical accounting policies and use of estimates from those disclosed in our accrued expenses to actual expenses.

Impairment of Long-Lived Assets
Management evaluatesForm 10-K for the recoverability of its property and equipment and amortizable intangible assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable or atyear ended December 31, 2020. For a minimum annually during the fourth quarter of the year. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of property and equipment and amortizable intangible assets is not recoverable, the carrying amount of such asset is reduced to fair value.

Acquired in-process research and development (IPR&D) assets are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Management evaluates the recoverability of its IPR&D assets for possible impairment annually during the fourth quarter or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of IPR&D assets is measured by a comparison of the carrying amounts to its fair value. If such review indicates that the carrying amount of IPR&D assets is not recoverable, the carrying amount of such asset is reduced to fair value.

Accounting for warrants

We have issued warrants to purchase shares of common stock related to equity transactions in 2017, 2018, 2019 and 2020. We account for our warrants issued in accordance with Accounting Standards Codification (ASC) Topic 480, Distinguishing Liabilities from Equity, ASC Topic 505, Equity, ASC Topic 815, Derivatives and Hedging, and ASC Topic 718, Compensation—Stock Compensation. Warrants are classified as liabilities when the Company may be required to settle a
24


warrant exercise in cash and classified as equity when the Company settles a warrant exercise in shares of its common stock. Based on this guidance, we determined that certaindiscussion of our warrantscritical accounting policies and use of estimates, refer to purchase sharesManagement’s Discussion and Analysis of common stock related to equity transactions meet the criteria for classification as a liability. Accordingly, the warrants were classified as a warrant liabilityFinancial Condition and are subject to fair value remeasurement at exerciseResults of Operations – Critical Accounting Policies and balance sheet date with the changesSignificant Estimates in fair value recognized in earnings.

Our financial instruments consist primarilyPart II, Item 7 of non-trade receivables, account payables, accrued expenses, and a warrant liability. The carrying amount of non-trade receivables, accounts payables, and accrued expenses approximates their fair value because of the short-term maturity of such.

We have categorized our assets and liabilities that are valued at fair valueAnnual Report on a recurring basis into three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous marketForm 10-K for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:
Level 1 - Unadjusted quoted prices in active markets of identical assets or liabilities.
Level 2 - Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3 - Unobservable inputs for the asset or liability.

Our financial assets and liabilities recorded at fair value on a recurring basis include the fair value of our warrant liability discussed above. The fair value of our liability classified warrants associated with the February 2017, February 2018, June 2018, March 2019, April 2019 and February 2020 Offerings (Offerings) are included in long-term liabilities on the accompanying financial statements as of March 31, 2020 andyear ended December 31, 2019.

We estimated the fair value of the warrant liability of a liability classified warrants pursuant to ASC Topic 820 as of their issuance date for financial reporting purposes, when exercised and balance sheet date. We used the Black-Scholes option pricing model (BSM) to determine the fair value of the warrants which is an acceptable method in accordance with GAAP. The BSM requires the use of a number of assumptions including volatility of the stock price, the weighted average risk-free interest rate, and the weighted average term of the Warrant.

The risk-free interest rate assumption is based upon observed interest rates on zero coupon US Treasury bonds whose maturity period is appropriate for the term of the warrants and is calculated by using the average daily historical stock prices through the day preceding the grant date.

Estimated volatility is a measure of the amount by which our stock price is expected to fluctuate each year during the expected life of the warrants. Beginning in 2020, we use the volatility of our stock in the BSM as we now have sufficient historic data in our stock price. Prior to 2020, we used the historical volatility of peer entities combined with our own due to the lack of sufficient historical data of our stock price

Changes in the fair value of our liability classified warrants during the reporting period are reflected as a gain (loss) from change in fair value of warrant liability in other income (expense) in our condensed consolidated statement of operations and comprehensive loss.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

Procedures

We maintain disclosure controls and procedures designed to ensure that material information required to be disclosed in our filings under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information is accumulated and communicated to our

25


management, including our Chief Executive Officer (CEO), who is our principal executive officer, and Chief Financial Officer (CFO), who is our principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosures. Our CEO and CFO have evaluated these disclosure controls and procedures as of the end of the period covered by this quarterly report on Form 10-Q and have determined that such disclosure controls and procedures were not effective as disclosed below.
In light of the material weakness described below, we performed additional procedures during the quarter and additional analysis and procedures post-closing to ensure our unaudited condensed consolidated financial statements were preparedMarch 31, 2021.

Changes in accordance with generally accepted accounting principles. Accordingly, we believe that the condensed consolidated financial statements included in this report fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented.

A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board Auditing Standard 1305) or combination of control deficiencies that result in more than a remote likelihood that a material misstatement of the annual or interim condensed consolidated financial statements will not be prevented or detected.

During the last quarter of fiscal 2016, and as our operational activities increased, management determined that it does not have sufficient segregation of duties within its accounting functions, which is a basic internal control. Due to our size and nature, segregation of all conflicting duties may not always be possible and may not be economically feasible. However, to the extent possible, the initiation of transactions, the custody of assets and the recording of transactions should be performed by separate individuals. Management evaluated the impact of our failure to maintain effective segregation of duties on our assessment of our internal control over financial reporting and has concluded that the control deficiency represents a material weakness. A number of the issues related to segregation of duties were remediated with new information technology systems and policies and procedures during 2019. Management added additional accounting and IT personnel in 2019 and implemented a new accounting software system, accounting policies, and banking controls. Management intends to further enhance its accounting staff and enhance the controls surrounding its system of financial accounting and reporting, as soon as economically feasible and sustainable, to further remediate this material weakness. During 2020, we implemented the ERP system for electronic payments and further updated roles, policies and procedures within those systems.

We continuously seek to improve the efficiency and effectiveness of our internal controls. Internal Control Over Financial Reporting

There has been no changes, except for items described above,change in our internal control over financial reporting that occurred(as defined in Rules 13a-15(f) and 15-d-15(f) under the Exchange Act) during the three months ended March 31, 20202021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Specifically, ourOur employees are working remotely due to the COVID-19 pandemic, but we do not believe that our adjustments to how we work have materially impacted our internal controls over financial reporting. We continue to monitor and accessassess the potential impact of the COVID-19 pandemic and the related shelter-in-place requirements, on our internal controls and strive to minimize the impact on our internal control design and operating effectiveness.

ITEM 1A. RISK FACTORS

For information regarding factors that could affect our results of operations, financial condition and liquidity, refer to the section entitled “Risk Factors” in Part I, Item 1A in our annual report on Form 10-K for the year ended December 31, 2019.2020. Except as updated below, there have been no material changes from the risk factors previously disclosed in our annual report on Form 10-K for the year ended December 31, 20192020 as filed with the SEC.


Changes to the patent law in the U.S. and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our future drugs and our drug candidates.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents that we license or hold directly. Obtaining and enforcing patents in the biopharmaceutical industry involve both technological and legal complexity and is therefore costly, time-consuming and inherently uncertain. Recent patent reform legislation in the U.S. and other countries, including the Leahy-Smith America Invents Act, or Leahy-Smith Act, signed into law on September 16, 2011, could increase those uncertainties and costs. The SEC issued an order suspendingLeahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the tradingway patent applications are prosecuted, redefine prior art and provide more efficient and cost-effective avenues for competitors to challenge the validity of patents. In addition, the Leahy-Smith Act has transformed the U.S. patent system into a first-to-file system. The first-to-file provisions, however, only become effective on March 16, 2013. Accordingly, it is not yet clear what, if any, impact the Leahy-Smith Act will have on the operation of our common stock.


On May 1, 2020,business. However, the SEC pursuantLeahy-Smith Act and its implementation could make it more difficult to Section 12(k)obtain patent protection for our inventions and increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could harm our business, results of operations and financial condition. The U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition, there have been recent proposals for additional changes to the patent laws of the Securities Exchange Act of 1934, as amended, orderedU.S. and other countries that, if adopted, could impact our ability to obtain patent protection for our proprietary technology or our ability to enforce our proprietary technology. Depending on future actions by the temporary suspension of tradingU.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the securities of Moleculin because of questions regarding the accuracyfuture.

We may be subject to adverse legislative or regulatory tax changes that could negatively impact our financial condition.

The rules dealing with U.S. federal, state and adequacy of informationlocal income taxation are constantly under review by persons involved in the marketplace about Moleculinlegislative process and its securities. Pursuantby the IRS and the U.S. Treasury Department. Changes to the suspension order, the suspension commenced at 9:30 a.m. EDT on May 4, 2020tax laws (which changes may have retroactive application) could adversely affect our stockholders or us. In recent years, many such changes have been made and terminates at 11:59 p.m. EDT on May 15, 2020. As of the date of this report, we have submitted a petitionchanges are likely to terminate the suspension, but there is no assurance that we will be successful. We believe we will be ablecontinue to demonstrate the accuracy and adequacy of our public disclosures, but the SEC may determine to extend the trading suspension until such time that it believes the informationoccur in the marketplace about usfuture. We cannot predict whether, when, in what form, or with what effective dates, tax laws, regulations and our securities is accurate and adequate.


With respect to the COVID-19 outbreak specifically, such outbreak could also potentially affect the business of the FDA, EMArulings may be enacted, promulgated or other health authorities,decided, which could result in delaysan increase in meetings relatedour, or our stockholders’, tax liability or require changes in the manner in which we operate in order to planned clinical trialsminimize increases in our tax liability. The impact of these and ultimately of reviewsother future changes in tax laws is uncertain and approvals of our product candidates.

The spread of COVID-19 may also slow potential enrollment of clinical trials and reduce the number of eligible patients for our clinical trials. The COVID-19 outbreak and mitigation measures also have had and may continue to have an adverse impact on global economic conditions which could have an adverse effect on our business, andcash flow, financial condition including impairing our ability to raise capital when needed. The extent to which the COVID-19 outbreak impacts our business and operations will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severityor results of the virus and the actions to contain its impact. We have relationships with contract research organizations to conduct certain pre-clinical programs and testing and other services in Europe and those business operations are subject to potential business interruptions arising from protective measures that may be taken by the governmental or other agencies or governing bodies. In addition, certain of our collaborative relationships with academic research institutions in the United States, Europe and in Australia may be materially and adversely impacted by protective measures taken by those institutions or federal and state agencies and governing bodies to restrict access to, or suspend operations at, such facilities. Such protective measures, including quarantines, travel restrictions and business shutdowns, may also negatively affect our core operations.
