Nature of Business

Panbela Therapeutics, Inc. and its wholly-owned subsidiary Panbela Therapeutics Pty Ltd (collectively “we,” “us,” “our,” and the “Company”) exist for the primary purpose of advancing the commercial development of a proprietary polyamine analogue for the treatment of patients with pancreatic cancer. We have exclusively licensed the worldwide rights to this compound, which has been designated as SBP-101, from the University of Florida Research Foundation, Inc. (“UFRF”).

The Company operates in a highly regulated and competitive environment. The development, manufacturing and marketing of pharmaceutical products require approval from, and are subject to ongoing oversight by, the Food and Drug Administration (“FDA”) in the United States, the Therapeutic Goods Administration in Australia, the European Medicines Agency in the European Union, and comparable agencies in other countries. Obtaining approval for a new pharmaceutical product is never certain, may take many years, and is normally expected to involve substantial expenditures.

We have incurred losses of $50.5$59.8 million since our inception in 2011. For the sixthree months ended June 30, 2021,March 31, 2022, we incurred a net loss of $4.4$3.7 million. We also incurred negative cash flows from operating activities of approximately $3.7$4.5 million for this period. As we continue to pursue development activities and seek commercialization of, our initial product candidate, SBP-101, we expect to incur substantial losses, which are likely to generate negative net cash flows from operating activities. As of June 30, 2021,March 31, 2022, we had cash and cash equivalents of $6.4$7.4 million, working capital of $5.8$3.4 million, (current assets less current liabilities) and stockholders’ equity of $5.9 million. On July 2, 2021, the company, in an underwritten transaction, sold 3,333,334 shares of common stock, the net proceeds of the transaction were approximately $9.0$6.6 million. The Company’s principal sources of cash have historically included the issuance of convertible debt and equity securities.

The accompanying condensed consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability or classification of assets or the amounts of liabilities that might result from the outcome of these uncertainties. Our current independent registered public accounting firm included a paragraph emphasizing this going concern uncertainty in their audit report regarding our 20202021 financial statements dated March 25, 2021.24, 2022. Our ability to continue as a going concern, realize the carrying value of our assets and discharge our liabilities in the ordinary course of business is dependent upon a number of factors, including our ability to obtain additional financing, the success of our development efforts, our ability to obtain marketing approval for our SBP-101 product candidate in the United States, Australia, the European Union or other markets and ultimately our ability to market and sell our SBP-101 product candidate. These factors, among others, raise substantial doubt about our ability to continue operations as a going concern. See Note 4 titled “Liquidity and Business Plan.”

In March 2020,2022 marked two years since the World Health Organization declared the spread of a novel strain of coronavirus (“COVID-19”) a global pandemic. Actions were taken byEarly in the pandemic, federal, state and local governmental authorities took actions to combat the spread of COVID-19, including through issuances of “stay-at-home” directives and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. These measures, while intended to protect human life, led to significantly reduced economic activity. Vaccines became available at the end of 2020, and distribution in the U.S. firstUnited States accelerated during the first quarter of 2021 and then leveled off in the second quarter. Most state and local authorities have reopened businesses and infectionsIn the fall of 2021, infection rates dropped through much of the second quarter. More recently infectionsincreased in the United States have started to increase againand other parts of the world as variants such asthe result of the delta variant, have become more prevalent.and in winter of 2021, infections again increased due to the omicron variant. In the first quarter of 2022, infection rates decreased. The rapid development and uncertainty of the situation continues to preclude any prediction as to the ultimate impact COVID-19 will have on the Company's business, financial condition, results of operationoperations and cash flows, which will depend largely on future developments directly or indirectly relating to the duration and scope of the COVID-19 outbreak in the United States, Australia, Europe and the rest of the world. During the spring of 2020 enrollment in our clinical trial was temporarily paused to allow our clinical sites time to prepare for COVID -19. We continued to treat patients already enrolled throughout the temporary pause in enrollment, and the study enrollment was completed in December of 2020. During the spring of 2021, the Company also experienced a delay in the manufacturing of the active product ingredient,substance, which is manufactured in India. There was also a delay in the final manufacturing steps which are completed in the United States, in part related to COVID-19. To date there has been no disruption in supply for our clinical or preclinical testing. The active ingredient for our nextIn January of 2022, the Company announced the opening of a global randomized Phase II/III clinical trial, has now been receivedwhich is expected to be conducted in the United States.States, Europe and Australia. The Company does not expect any disruption to the conduct of this new clinical trial associated with COVID-19. The Company’s administrative operations have been decentralized since inception so the Company experienced no administrative disruptions or additional costs due to the pandemic or related restrictions.

We have prepared the accompanying interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring accruals, which, in the opinion of management, are necessary to present fairly our consolidated financial position, consolidated results of operations and consolidated cash flows for the periods and as of the dates presented. Our fiscal year ends on December 31. The condensed consolidated balance sheet as of December 31, 2020,2021 was derived from audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto included in our most recent filed Annual Report on Form 10-K and our subsequent filings with the SEC. The nature of our business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.

We will need to raise additional capital to support our current business plans. We may seek to raise additional funds through various sources, such as equity and debt financings, or through strategic collaborations and license agreements. We can give no assurances that we will be able to secure additional sources of funds to support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or on terms acceptable to us. This risk would increase if our clinical data were not positive or economic and market conditions deteriorate.

On July 2, 2021, subsequent to the end of the period, the Company completed an underwritten public offering of 3,333,334 shares of common stock at $3.00 per share which resulted in net proceeds of approximately $9.0$9.1 million.

Between In the February 5 firstand quarter of March 23, 2021,the company issued 228,938Company received net proceeds of approximately $1.0 million from the exercise of common stock warrants; a total 228,939 shares of common stock as the result of the exercise of outstanding warrants. Total cash received was approximately $1.0 million.were issued.

On September 1, 2020, the Company completed an underwritten public offering of 2,545,454 shares of common stock and warrants to purchase the same number of shares of common stock which resulted in net proceeds of approximately $9.3 million. In the quarter ended June 30, 2020, the Company sold common stock and warrants to purchase common stock in private placements to certain accredited investors resulting in net proceeds of approximately $1.7 million.

We will need to raise additional capital to fully fund the randomized clinical trial set to begin enrollment at the end of 2021.OurOur future success is dependent upon our ability to obtain additional financing, the success of our development efforts, our ability to obtain marketing approval for our SBP-101 product candidate in the United States or other markets and ultimately our ability to market and sell our SBP-101 product candidate. If we are unable to obtain additional financing when needed, if our clinical trials are not successful or if we are unable to obtain marketing approval, we would not be able to continue as a going concern and would be forced to cease operations and liquidate our company.

There can be no assurances that we will be able to obtain additional financing on commercially reasonable terms, or at all. The sale of additional convertible debt or equity securities would likely result in dilution to our current stockholders.

Principles of consolidation

The accompanying condensed consolidated financial statements include the assets, liabilities, and expenses of the Company. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amount of expenses during the reporting period. Actual results could differ from those estimates, particularly given the significant social and economic disruptions and uncertainties with the ongoing pandemic and control responses.

Research and development costs

Research and development costs include expenses incurred in the conduct of our second Phase 1 human clinical trial, for third-party service providers performing various testing and accumulating data related to our preclinical studies; sponsored research agreements; developing and scaling the manufacturing process necessary to produce sufficient amounts of the SBP-101 compound for use in our pre-clinical studies and human clinical trials; consulting resources with specialized expertise related to execution of our development plan for our SBP-101 product candidate; personnel costs, including salaries, benefits and share-based compensation; and costs to license and maintain our licensed intellectual property.

We charge research and development costs, including clinical trial costs, to expense when incurred. Our human clinical trials are, and will be, performed at clinical trial sites and are administered jointly by us with assistance from contract research organizations (“CROs”). Costs of setting up clinical trial sites are accrued upon execution of the study agreement. Expenses related to the performance of clinical trials generally are accrued based on contracted amounts and the achievement of agreed upon milestones, such as patient enrollment, patient follow-up, etc. We monitor levels of performance under each significant contract, including the extent of patient enrollment and other activities through communications with the clinical trial sites and CROs, and adjust the estimates, if required, on a quarterly basis so that clinical expenses reflect the actual effort expended at each clinical trial site and by each CRO.

All material CRO contracts are terminable by us upon written notice, and we are generally only liable for actual effort expended by the CROs and certain non-cancelable expenses incurred at any point of termination.

We expense costs associated with obtaining licenses for patented technologies when it is determined there is no alternative future use of the intellectual property subject to the license.

Stock-based compensation

In accounting for stock-based incentive awards, we measure and recognize the cost of employee and non-employee services received in exchange for awards of equity instruments based on the fair value of those awards on the grant date. Calculating stock-based compensation expense requires the input of highly subjective assumptions, which represent our best estimates and involve inherent uncertainties and the application of management’s judgment. Compensation cost is recognized ratably using the straight-line attribution method over the vesting period, which is considered to be the requisite service period. Compensation expense for performance-based stock option awards is recognized when “performance” has occurred or is probable of occurring.

The fair value of stock-based awards is estimated at the date of grant using the Black-Scholes option pricing model. The determination of the fair value of stock-based awards is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables. Risk free interest rates are based upon U.S. Treasury rates appropriate for the expected term of each award. Expected volatility rates are based primarily on the volatility rates of a set of guideline companies, which consist of public and recently public biotechnology companies. The assumed dividend yield is zero, as we do not expect to declare any dividends in the foreseeable future. The expected term of options granted is determined using the “simplified” method. Under this approach, the expected term is presumed to be the mid-point between the average vesting date and the end of the contractual term.

Foreign currency translation adjustments

The functional currency of Panbela Therapeutics Pty Ltd is the Australian Dollar. Accordingly, assets and liabilities, and equity transactions of Panbela Therapeutics Australia Pty Ltd, are translated into U.S. dollars at period-end exchange rates. Revenues and expenses are translated at the average exchange rate in effect for the period. The resulting translation gains and losses are recorded as a component of accumulated comprehensive loss presented within the stockholders’ equity. During the three and six-month periods ended June 30, 2021,March 31, 2022 and 2020,2021, any reclassification adjustments from accumulated other comprehensive loss to operations were inconsequential.

Comprehensive loss

Comprehensive loss consists of our net loss and the effects of foreign currency translation.

Net loss per share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is based on the weighted average of common shares outstanding during the period plus dilutive potential common shares calculated using the treasury stock method. Such potentially dilutive shares are excluded when the effect would be anti-dilutive or reduce a net loss per share. The Company’s potential dilutive shares, which include outstanding common stock options, and warrants, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the potential shares of common stock that were not included in the calculation of diluted net loss per share as their effects would have been anti-dilutive as of the dates indicated:

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU No.2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This ASU is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. The Company has adopted the ASU for the year ended December 31, 2022. This update permits the use of either the modified retrospective or fully retrospective method of transition. The Company has determined that the impact this ASU will have on its consolidated financial statements is not material.

Warrants exercised and expired

During the six months ended June 30, 2021, the Company issued a total of 228,939 shares of common stock for a total of approximately $1.0 million, resulting from exercises of outstanding warrants. During the same period, the Company issued an additional 190,588 shares of common stock resulting from the net, cashless, exercise of outstanding warrants to purchase 536,140 shares. Warrants to purchase a total of 573,339 shares of common stock, all having an exercise price of $5.00 per share, expired during the six months ended June 30, 2021. Additionally, warrants to purchase 108,550 shares of common stock, with an exercise price of $15.00 expired during the six months ended June 30, 2021.

Overview

We exist for the primary purpose of advancing the commercial development of our proprietary polyamine analogue in solid tumors with an initial focus on pancreatic cancer.

We have exclusively licensed the worldwide rights to this compound, which has been designated as SBP-101, from the UFRF.University of Florida Research Foundation, Inc.

In August 2015, the FDAFood and Drug Administration (“FDA”) accepted our Investigational New Drug (“IND”) application for our SBP-101 product candidate.

In 2017 weWe have completed an initial clinical trial of SBP-101 in patients with previously treated locally advanced or metastatic pancreatic cancer. This was a Phase 1,I, first-in-human, dose-escalation, monotherapy safety study. From January 2016 through September 2017, we enrolled twenty-nine patients into six cohorts, (cohorts 5a and 5b while the same dose, were separated as the result of different manufacturing lots)or groups, in the dose-escalation phase of the Phase 1I trial. No drug-related bone marrow toxicity or peripheral neuropathy was observed at any dose level. In addition to being evaluated for safety, 23 of the 29 patients were evaluable for preliminary signals of efficacy prior to or at the eight-week conclusion of their first cycle of treatment using the Response Evaluation Criteria in Solid Tumors (“RECIST”), the currently accepted standard for evaluating change in the size of tumors. Eight of the 23 patients (35%) had stable disease (“SD”) and 15 of 24 (65%) had progressive disease (“PD”). It should be noted that of the 15 patients with PD, six came from cohorts one and two and are considered to have received less than potentially therapeutic doses of SBP-101. We also noted that 28 of the 29 patients had follow-up blood tests measuring the Tumor Marker CA 19-9 associated with pancreatic ductal adenocarcinoma. Eleven of these patients (39%) had reductions in the CA 19-9 levels, as measured at least once after the baseline assessment. Seven of the remaining 17 patients who showed no reduction in CA 19-9 came from cohorts one and two.

In December of 20202018, we completed enrollment ofbegan enrolling patients in our second clinical trial, a Phase 1a/1bIa/Ib study of the safety, efficacy and pharmacokinetics of SBP-101 administered in combination with two standard-of-care chemotherapy agents, gemcitabine and nab-paclitaxel. A total of 25 subjects were enrolled in 4 cohorts in the Phase 1a portion of the trial to evaluate the dosage level and schedule. An additional 25 subjects were enrolled in the expansion or Phase 1b portionphase of the trial. On JuneInterim results were presented in January of 2022. Best response in evaluable subjects (cohorts 4 2021, weand Ib N=29) was a CR in 1 (3%), PR in 13 (45%), SD in 10 (34%) and PD in 5 (17%). One subject did not have post baseline scans with RECIST tumor assessments.

In January of 2022, the Company announced the presentationinitiation of interima new clinical data from ourtrial. Referred to as ASPIRE, the trial is a Phase 1 combination therapy study, “SBP-101, a polyamine metabolic inhibitor, administeredII/III randomized double-blind placebo-controlled trial in combination with gemcitabine and nab-paclitaxel, (“G+A”), shows signals of efficacy as first-linea standard pancreatic cancer treatment regimen in patients previously untreated for subjects with metastatic pancreatic ductal adenocarcinoma (“PDA”),”cancer. The trial will be conducted globally at approximately 60 sites in the United States, Europe and Asia - Pacific.

In early April 2022, the Company announced a poster presentation highlighting the results for SBP-101 as a polyamine metabolism modulator in ovarian cancer at the American SocietyAssociation for Cancer Research. The poster concludes that the treatment of Clinical Oncology (“ASCO”) Annual Meeting held June 4-8, 2021. C57Bl/6 mice injected with VDID8+ ovarian cancer with SBP-101 significantly prolonged survival and decreased overall tumor burden. The results suggest that SBP-101 may have a role in the clinical management of ovarian cancer, and the Company intends to continue pre-clinical and clinical studies in ovarian cancer.

SBP-101 was well-tolerated when administered at doses and schedules tested in combination with G+A in subjects with previously untreated metastatic PDA. The most common Grade ≥3 adverse events (“AEs”) related to any study medication were neutropenia in 20 subjects (19 attributed to G+A and 1 attributed to all 3) and elevated liver function tests (“LFTs”) in 15 subjects (5 attributed to SBP-101 and 10 attributed to all 3). SBP-101-related increases in LFTs were asymptomatic in all but 2 subjects and reversed in all but 1 subject when SBP-101 administration was interrupted and dose-reduced or discontinued. Six subjects experienced vision AEs (3 possibly related to SBP-101, 1 related to gemcitabine and 2 related to all 3 based on principal investigator assessment. All were considered by the sponsor to be possibly related to SBP-101; 5 subjects had findings consistent with retinopathy. Future studies will exclude patients with a history of retinopathy or at risk of retinal detachment and scheduled ophthalmologic monitoring for all patients. Additionally, in future dose-finding studies screening for retinal toxicity will be included.

Interim efficacy was reported for 29 response-evaluable subjects in Cohort 4 + Phase 1b as well as for 7 subjects in Cohort 2.  Eleven subjects in Cohort 4 + Phase 1b had treatment with SBP-101 interrupted to evaluate retinal toxicity. The dose level in Cohort 4 + Phase 1b was the same as Cohort 2; however, the dose schedule was altered. The dose interruption may confound final efficacy results for Cohort 4 + Phase 1b. In Cohort 2 (N=7), the objective response rate (“ORR”) was 71%, and the disease control rate (“DCR”) was 100% by RECIST criteria (SD or better for ≥ 16 weeks). Median progression free survival (“PFS”) in Cohort 2 was 5.6 months and median overall survival (“OS”) was 10.3 months. In Cohort 4 + Phase 1b (N=29), the ORR was 48%, DCR was 70%, and PFS was 5.2 months; median OS has not been reached in Cohort 4 + Phase 1b to date. Subsequent to the release of this data in our poster at ASCO, one subject with a partial response converted to a complete response (“CR”) and one subject while non-CR by RECIST criteria had no evidence of disease.

The Company believes that the interim results of the front-line clinical trial of our SBP-101 product candidate justify continued development. Additional clinical trials willmay be required for FDA or other country approvals. We expect to begin a randomized clinical trial of SBP-101 administered in combination with two standard-of-care chemotherapy agents, gemcitabine and nab-paclitaxel for first line treatment of metastatic PDA in the second half of 2021. The cost and expected durationtiming of this randomizedadditional clinical trialtrials is highly dependent on the nature and size of the trial which is still in planning at this time.trials.

We are also exploring SBP-101 for neo-adjuvant treatment in appropriate patients. There is also preclinical data to suggest that SBP-101 may have potential therapeutic uses for cancers other than pancreatic. InPending Acquisition

We have incurred losses of $50.5$59.8 million since 2011. For the sixthree months ended June 30, 2021,March 31, 2022, we incurred a net loss of $4.4$3.7 million. We also incurred negative cash flows from operating activities of approximately $3.7$4.5 million for this period. We expect to continue to incur substantial losses, which will generate negative net cash flows from operating activities, as we continue to pursue research and development activities and commercialize our SBP-101 product candidate.commercialize.

Our cash was approximately $6.4$7.4 million and $9.0$11.9 million as of June 30, 2021March 31, 2022 and December 31, 2020,2021, respectively.

A decrease of $2.6$4.5 million in cash for the sixthree months ended June 30, 2021March 31, 2022 was due to negative cash flow from operations of approximately $3.7which included $2.6 million offset in part from funds generated fromto fund long term deposits held by the exercise of warrants.

Other thanCRO leading our randomized trial. This cash balance is expected, due to the temporary pause in enrollment during April and May of 2020 inincreased spending on our currentnew randomized clinical trial, the Company has not experienced any significant disruptions to our operations as a result of the COVID-19 pandemic. Recruitment and enrollment were resumed in May of 2020 and completed in December of 2020. The Company was not required to change management practices as it was decentralized prior to the COVID-19 pandemic.

Based on anticipated use of cash we expect the proceeds of the sale of equity securities that occurred in September of 2020 and July of 2021 will be sufficient to fund our expectedsustain operations into the firstfourth quarter of 2023, however there can be no assurance to this estimate. 2022.

We will need to obtainraise additional fundscapital to continue our operations and execute our current business plans,plan past the fourth quarter of 2022, including completing required future trials and pursuing regulatory approvals in the United States, the European Union and other international markets, and laboratory studies to explore potential indications in other cancer types.markets. We historically have financed our operations principally from the sale of equity securities and debt. While we have been successful in the past in obtaining the necessary capital to support our operations and havewe are likely to seek additional financing through similar future plans to obtain additional financing,means, there is no assurance that we will be able to obtain additional financing under commercially reasonable terms and conditions, or at all. This risk would increase if our clinical data were inconclusive or not positive or if economic or market conditions worsen indeteriorate.

If we are unable to obtain additional financing when needed, we would need to scale back our operations, taking actions which may include, among other things, reducing use of outside professional service providers, reducing staff or staff compensation, significantly modifying or delaying the marketdevelopment of our SBP-101 product candidate, license licensing to third parties the rights to commercialize our SBP-101 product candidate for pancreatic cancer or other applications that we would otherwise seek to pursue, or cease ceasing operations.

The Company has not experienced any significant disruptions to our operations as a whole orresult of the COVID-19 pandemic. Recruitment and enrollment in our Phase Ia/Ib trial was paused for a brief time in April and May of 2020. Drug product was delayed in early 2022, but we had adequate supply to initiate our randomized Phase II/III clinical trial and experienced no product related disruptions to our clinical trials. The Company was not required to change management practices as it was decentralized prior to the pharmaceutical or biotechnology markets individually.COVID-19 pandemic.

Results of Operations

Comparison of the results of operations (in thousands):

General and administrative (“G&A”) expenses consist primarily of salaries, incentive compensation and other employee benefits, including stock-based compensation. Other G&A expenses include professional fees for accounting and tax, legal services, insurance, and costs associated with being a publicly traded company including directors and officer’s liability insurance premiums.

Research and development (“R&D”) expenses consist primarily of clinical and regulatory costs, costs incurred under agreements with contract research organizations, pre commercial manufacturinggeneral and stability testing and employee compensation related expenses.

R&D and administrative (“G&A&A”) expenses include non-cash stock-basedshare-based compensation expense because ofresulting from our issuancesissuance of stock options. We expense the fair value of equity awards over their vesting periods. The terms and vesting schedules for share-based awards vary by type of grant and the employment status of the grantee. The awards granted through September 30, 2020March 31, 2022 vest upon performance andor time-based conditions.

General and administrative expense

Our G&A expenses increased 56.3% to $1.8 million in the first quarter of 2022, up from $1.1 million in the first quarter of 2021. The increase is primarily associated with legal and other costs associated with the Company’s proposed merger with CPP.

Research and development expense

Our R&D expenses increased 100.9% to $2.2 million in the first quarter of 2022, up from $1.1 million in the first quarter of 2021. The increase is due primarily to increased clinical trial costs related to our new randomized Phase II/III trial in the first quarter of 2022.

Cash Flows

Net Cash Used in Operating Activities

Net cash used in operating activities was approximately $3.7$4.5 million in the sixthree months ended June 30, 2021March 31, 2022 compared to approximately $2.0 million in the sixthree months ended June 30, 2020.March 31, 2021. The net cash used in each of these periods primarily reflects the net loss for these periods and is partially offset by the effects of changes in operating assets and liabilities and non-cash stock compensation expense.liabilities. For the quarter ended March 31, 2022, cash used in operating activities also included $2.6 million to fund long term deposits held by the CRO leading our randomized trial.

On July 2, 2021 the company sold 3,333,334 shares of common stock, which provided incremental cash of approximately $9.0 million.quarter.

Capital Requirements

As we continue to pursue our operations and execute our business plan, including the wrapping up our current Phase 1 clinical trial and initiating a randomized trial for our initial product candidate, SBP-101, in pancreatic cancer, planning for required future trials and pursuing regulatory approvals in the United States, the European Union and other international markets, we expect to continue to incur substantial and increasing losses, which will continue to generate negative net cash flows from operating activities.

Our future capital uses and requirements depend on numerous current and future factors. These factors include, but are not limited to, the following:

To date, we have used primarily equity financings and convertible debt to fund our ongoing business operations and short-term liquidity needs, and we expect to continue this practice for the foreseeable future. As of June 30, 2021,March 31, 2022, we did not have any existing credit facilities under which we could borrow funds.

We expect that we will have increases in expenditures in order to continue our efforts to grow our business, complete our Phase 1a clinical trial and begin the next clinical trial for our SBP-101 product candidate. We also have begun to invest in additional R&D efforts on mechanism of action, biomarkers, additional indications in other cancer types and the possibility of SBP-101 to act as a sensitizing agent for certain immunotherapies. The exact amounts and timing of any expenditure may vary significantly from our current intentions. We will need to obtain additional funds to continue our operations and execute our business plans including completion of required future trials and pursuing regulatory approvals in the United States, the European Union and other international markets. While we have been successful in the past in obtaining the necessary capital to support our operations, and have similar future plans to obtain additional financing, there is no assurance that we will be able to obtain additional financing under commercially reasonable terms and conditions, or at all. This risk would increase if our clinical data were inconclusive or not positive or economic conditions worsened in the market as a whole or in the pharmaceutical or biotechnology markets individually.

If we are unable to obtain additional financing when needed, we will likely need to reduce our operations by taking actions which may include, among other things, reducing use of outside professional service providers, reducing staff size or reduce staff compensation, significantly modifying or delaying the development of our SBP-101 product candidate,, licensing rights to third parties, including the right to commercialize our SBP-101 product candidate for patients with pancreatic cancer, or other applications that we would otherwise seek to pursue, or discontinuing operations entirely.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, the interests of our current stockholders could be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of our current stockholders. If we issue preferred stock, it could affect the rights of our stockholders or reduce the value of our common stock. Specific rights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any of these events could adversely affect our ability to achieve our regulatory approvals and commercialization goals and harm our business.

Our future success is dependent upon our ability to obtain additional financing, the success of our current Phase 1 clinical trial and required future trials, our ability to obtain marketing approval for our SBP-101 product candidate in the United States, the European Union and other international markets. If we are unable to obtain additional financing when needed, if our Phase 1 clinical trial is not successful, if we do not receive regulatory approval required for future trials or if once these studies are concluded, we do not receive marketing approval for our SBP-101 product candidate, we would not be able to continue as a going concern and would be forced to cease operations. The interim financial statements included in this report have been prepared assuming that we will continue as a going concern and do not include any adjustments relating to the recoverability or classification of assets or the amounts of liabilities that might result from the outcome of these uncertainties.

Indebtedness

As of June 30, 2021March 31, 2022 and December 31, 20202021 we had no debt obligations.

Critical Accounting Policies and Estimates

Our significant accounting policies and estimates are set forth in the notes accompanying the condensed consolidated financial statements included in this document. The accounting policies and estimates used in preparing our interim fiscal 20212022 condensed consolidated financial statements are the same as those described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.2021.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

As a smaller reporting company, we are not required to provide disclosure pursuant to this item.

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. As of the date of this filing, management has not identified any material weaknesses, but believes that it does have a significant deficiency in that it has insufficient personnel resources within the accounting function to fully segregate the duties over financial transaction processing and reporting. Management has mitigated this deficiency primarily through greater involvement in the review and monitoring of financial transaction processing and reporting by executive and senior management.

We believe that our internal control system provides reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. All internal controls over financial reporting, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention or overriding of controls. Therefore, even effective internal controls over financial reporting can provide only reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal controls over financial reporting may vary over time.

As of the end of the period covered by this quarterly report, the Company’s management conducted an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, pursuant to Rules 13a-15 and 15d-15 of the Exchange Act. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2021,March 31, 2022, our disclosure controls and procedures were effective in ensuring that information relating to the Company required to be disclosed in the reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes to Internal Control Over Financial Reporting

We have not identified any change in our internal control over financial reporting during our most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

None.

Other than as noted below, thereThere have been no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Our business is subject to risks arising from epidemic diseases, such as the 2020 outbreak of the COVID-19 illness.

The outbreak of COVID-19, which was declared in March 2020 by the World Health Organization to be a pandemic, has spread across the globe and is impacting worldwide economic activity. A pandemic, including COVID-19, or other public health epidemic poses the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time, including due to the spread of the disease within these groups or due to shutdowns that may be requested or mandated by governmental authorities. During the second quarter of 2020 we paused enrollment in our clinical trial for 6 weeks to allow the health care systems involved in the trial time to focus resources on responding to the pandemic. We continued to treat patients previously enrolled. Once enrollment was restarted in May 2020, we experienced no further delays. This delay did not have a material effect on the completion of enrollment or costs of the clinical trial. During the course of the pandemic, health care facilities have limited our ability to conduct on site patient data monitoring for our clinical trial, these visits are now successfully conducted remotely as necessary. We also experienced a delay, approximately 30 to 60 days, early in the pandemic, in the manufacturing of our active ingredient. We believe our supply of drug is adequate and we do not expect this delay to disrupt the current trial or anticipated new trial to be initiated in 2021.

While we have not, to date experienced any significant disruptions as a result of the pandemic, we are unable to estimate the future impact that COVID-19 could have on our operations. The continued spread of COVID-19, limited availability of approved vaccines and measures taken by governmental authorities in light of the same may slow potential enrollment of clinical trials and reduce the number of eligible patients for our clinical trials. The pandemic could also disrupt the supply chain and the manufacture or shipment of both drug substance and finished drug product for our product candidates for preclinical testing and clinical trials and adversely impact our business, financial condition or results of operations. We often attend and present clinical updates at various medical and investor conferences throughout the year. The COVID-19 outbreak has caused, and is likely to continue to cause, cancellations or reduced attendance of these conferences and we may need to seek alternate methods to present clinical updates and to engage with the medical and investment communities. The COVID-19 outbreak and mitigation measures may also have an adverse impact on global economic conditions which could have an adverse effect on our business and financial condition and our potential to conduct financings on terms acceptable to us, if at all. The extent to which the COVID-19 outbreak impacts our results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.

The Company did experience a modest delay in shipment of the active ingredient from India to the United States as a result of increased COVID-19 cases in India in the first half of 2021. The product was received early July 2021 for filling and labeling. To the extent possible the spread of the Delta variant is being considered in our assumptions as the Company plans for a new clinical trial to be initiated, likely to be conducted in many different locations, in the second half of 2021. At this time no disruption to the initiation of the new trial is anticipated.
