Business

 

Nature of Business

Panbela Therapeutics, Inc. (“Panbela”) and its wholly-owned subsidiarydirect wholly owned subsidiaries: Panbela Research, Inc. (“Panbela Research”) Cancer Prevention Pharmaceuticals, Inc. (“CPP”) and Cancer Prevention Pharma (Ireland) Limited exist for the primary purpose of developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs. Panbela Therapeutics Pty Ltd (collectivelyis a wholly owned subsidiary of Panbela Research organized under the laws of Australia. Cancer Prevention has two wholly owned dormant subsidiaries: Cancer Prevention Pharma Limited, a United Kingdom entity, and Cancer Prevention Pharmaceuticals, LLC, an Arizona limited liability company. Panbela Therapeutics, Inc., together with its direct and indirect subsidiaries is referred to as “we,” “us,” “our,” and the “Company”“Company.”

The primary objective of our pipeline is the utilization of pharmacotherapies to reduce or normalize increased disease-associated polyamines using complementary pharmacotherapies. Our lead candidates are ivospemin (SBP-101) exist for the primary purpose of advancing the commercial development of a proprietary polyamine analogue for the treatment of patients with pancreatic cancer. Wewhich 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. and Flynpovi™ a combination of eflornithine (CPP-1X) and sulindac. We have exclusively licensed rights from the Arizona Board of Regents of the University of Arizona to commercialize Flynpovi, and a sublicense agreement to develop and commercialize Flynpovi in North America was terminated by the licensee on April 4, 2023.

Reverse stock split

Effective January 13, 2023, Panbela effected a 1-for-40 reverse stock split of its outstanding shares of common stock. Unless specifically provided otherwise herein, all share and per share amounts of our common stock presented have been retroactively adjusted to reflect the reverse stock split. See Note 7 for more information.

Risks and Uncertainties

 

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”(the “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 $59.8$96.2 million since our inception in 2011. For the three months ended March 31, 2022,2023, we incurred a net loss of $3.7$5.1 million. We also incurred negative cash flows from operating activities of approximately $4.5$9.8 million for this period. As we continue to pursue development activities and seek commercialization, of, we expect to incur substantial losses, which are likely to generate negative net cash flows from operating activities. We incurred approximately $13.7 million positive cash flows from financing activities related to proceeds from the sale of common stock, prefunded warrants, and warrants, partially offset by the payments made on two promissory notes. As of March 31, 2022,2023, we had cash of $7.4approximately $5.2 million, working capital deficit of $3.4$1.9 million, (current(working capital is defined as current assets less current liabilities) and stockholders’ equity of $6.6$2.5 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 20212022 financial statements dated March 24, 2022.16, 2023. 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-101product candidatecandidates in the United States, Australia, the European Union or other markets and ultimately our ability to market and sell our SBP-101product candidate.candidates. 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.”

March 20222023 marked twothree years since the World Health Organization declared the spread of a novel strain of coronavirus (“COVID-19”) a global pandemic. Early 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 United States accelerated during the first quarter of 2021 and then leveled off in the second quarter. In the fall of 2021, infection rates increased in the United States and other parts of the world as the result of the delta variant, 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 operations 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 2021, the Company also experienced a delay in the manufacturing of the active product 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 the supply of our active drug substance for our clinical or preclinical testing. In January of 2022, the Company announced the opening of a global randomized Phase II/III clinical trial, which is expected to be conducted in the United States, Europe and Australia.Asia Pacific (APAC). 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 duetrial is reliant on adequate supply of gemcitabine and Abraxane (nab-paclitaxel) which can be subject to the pandemic or related restrictions.supply shortages.

Basis of Presentation

 

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, 20212022, 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.

Liquidity and Business Plan

 

On January 30, 2023, the Company completed a registered public offering of common stock, prefunded warrants and warrants which resulted in net proceeds of approximately $13.8 million. Also in the first quarter of 2023, the Company received net proceeds of approximately $1.6 million from the sale of common stock via the Company’s At-the-Market facility.

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,financing, 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, 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 $9.1 million. In the first quarter of 2021, the Company received net proceeds of approximately $1.0 million from the exercise of common stock warrants; a total 228,939 shares of common stock were issued.

Our future success is dependent upon our ability to obtain additional financing, the success of our development efforts, our ability to obtain marketing approval for SBP-101our product candidates ivospemin, Flynpovi and eflornithine in the United States or other markets and ultimately our ability to market and sell our SBP-101product candidate.candidates. 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.

Summary of Significant Accounting Policies

 

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.

8

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,trials; 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 compounddrug product for our product candidates 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-101product candidate;candidates; 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.

 

The cost to secure certain third-party drug product for the clinical trials, which is often paid for in advance of delivery, is charged to research and development when it is received and available to be shipped to clinical sites.

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.historical company share price volatility. 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-month periods ended March 31, 20222023 and 2021,2022, 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 beis anti-dilutive or reduce a net loss per share. The Company’s potentialpotentially 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.

Overview

 

We existPanbela Therapeutics, Inc. (“Panbela” and together with its direct and indirect subsidiaries, “we,” “us,” “our,” and the “Company”) is a clinical stage biopharmaceutical company developing disruptive therapeutics for the primary purposetreatment of advancing the commercial development of our proprietary polyamine analogue in solid tumorspatients with an initial focus on pancreatic cancer.urgent unmet medical needs.

 

WeOn June 15, 2022, Panbela completed the previously announced strategic business reorganization and acquisition of Cancer Prevention Pharmaceuticals, Inc. (“CPP”) pursuant to the agreement and plan of merger, dated as of February 21, 2022 (the “Merger Agreement”), by and among Panbela, CPP and Panbela Research, Inc. (formerly known as Panbela Therapeutics, Inc., “Panbela Research”), among others. Pursuant to the terms of the Merger Agreement, (i) Canary Merger Subsidiary I, Inc. (“Merger Sub I”), then a wholly-owned subsidiary of Panbela, which was itself a wholly-owned subsidiary of Panbela Research, merged with and into Panbela Research (the “First Merger”), with Panbela Research surviving the First Merger, and (ii) Canary Merger Subsidiary II, Inc., then a wholly-owned subsidiary of Panbela, merged with and into CPP (the “Second Merger” and, together with the First Merger, the “Mergers”), with CPP surviving the Second Merger. As a result of the Mergers, each of Panbela Research and CPP became a wholly owned subsidiary of Panbela. In addition, in connection with the consummation of the Mergers, “Panbela Therapeutics, Inc.” was renamed “Panbela Research, Inc.” and “Canary Merger Holdings, Inc.” was renamed “Panbela Therapeutics, Inc.”

Our lead candidates are ivospemin (SBP-101) for which 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. and Flynpovi (eflornithine (CPP-1X) and Sulindac). Flynpovi is delivered in an oral form. The Company has an exclusive worldwide license to commercialize Flynpovi from the Arizona Board of Regents of the University of Arizona.

Ivospemin (SBP-101)

 

In August 2015, the Food and Drug Administration (“FDA”)FDA accepted our Investigational New Drug (“IND”) application for our SBP-101ivospemin product candidate. In May of 2022 we were notified that the United States Adopted Names (“USAN”) had adopted ivospemin as a USAN for SBP-101. The USAN information on ivospeminwas posted on the USAN Web site (www.ama-assn.org/go/usan).

14

 

We have completed an initial clinical trial of SBP-101ivospemin in patients with previously treated locally advanced or metastatic pancreatic cancer. This was a Phase I, first-in-human, dose-escalation, safety study. From January 2016 through September 2017, we enrolled twenty-nine patients into six cohorts, or groups, in the dose-escalation phase of the Phase I 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.

 

In 2018, we began enrolling patients in our second clinical trial, a Phase Ia/Ib study of the safety, efficacy and pharmacokinetics of SBP-101ivospemin administered in combination with two standard-of-care chemotherapy agents, gemcitabine and nab-paclitaxel. A total of 25 subjects were enrolled in 4four cohorts to evaluate the dosage level and schedule. An additional 25 subjects were enrolled in the expansion phase of the trial. Interim results were presented in January of 2022. Best response in evaluable subjects (cohorts 4 and 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. Median PFS, now final at 6.5 months, may have been negatively impacted by drug dosing interruptions to evaluate potential toxicity. Median overall survival in Cohort 4 + Phase Ib was 12.0 months when data was presented in January 2022 and is now final at 14.6 months. Two patients from cohort 2 have demonstrated long term survival. One at 30.3 months (final data) and one at 33.0 months and still alive at data base lock on March 18, 2022. Seven subjects are still alive at database lock, one from cohort 2 and six from cohort 4 plus Ib.

 

In January of 2022, the Company announced the initiation of a new clinical trial. Referred to as ASPIRE, the trial is a Phase II/III randomized double-blind placebo-controlled trial in combination with gemcitabine and nab-paclitaxel, a standard pancreatic cancer treatment regimen in patients previously untreated for metastatic pancreatic cancer. The trial will be conducted globally at approximately 6095 sites in the United States, Europe and Asia - Pacific. The company announced the first patient enrolled in the trial in Australia in August of 2022. In September, the company announced that they had obtained regulatory approval to open sites in Spain, France and Italy. On March 31, 2023 there were 45 sites open in 7 countries.

While opening of clinical sites in the United States and the rest of the world has been slower than originally anticipated, due in part to resource fatigue in the medical community, the Company expects all countries and sites to be open by mid-2023.

The trial was originally designed as a Phase II/III with a smaller initial sample size (150) to support the events required for interim analysis based on progression-free survival (PFS) and a primary endpoint of overall survival. In response to European and FDA regulatory feedback, the study was amended to include the total trial sample size (600) and the design modified to utilize overall survival as the primary endpoint to be examined at interim analysis. PFS will also be analyzed to provide additional efficacy evidence. This amendment was supported by the final data from the Phase Ia/Ib first line metastatic pancreatic trial which completed enrollment in December of 2020. The study will enroll 600 subjects and is anticipated to take 36 months for complete enrollment with the interim analysis available in early 2024.

In early April 2022,2023, the Company announced a poster presentation highlighting the results for SBP-101ivospemin as a polyamine metabolism modulator in ovarian cancer at the American Association for Cancer Research.Research Annual Conference The poster concludes that the ivospemin chemotherapy treatment of C57Bl/6 mice injected with VDID8+ ovarian cancer with SBP-101cells significantly prolonged survival and decreased overall tumor burden. The results suggest that SBP-101ivospemin in combination with standard of care chemotherapy 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.

 

Additional clinical trials may be required for FDA or other country approvals. The cost and timing of additional clinical trials isare highly dependent on the nature and size of the trials.

 

Pending AcquisitionFlynpovi (eflornithine (CPP-1X) and sulindac)

 

As previously announced, on February 21, 2022, Panbela entered intoIn 2009, the FDA accepted our IND application for the combination product, Flynpovi, product candidate.

In a definitive agreement to acquire Cancer Prevention Pharmaceuticals, Inc. (“CPP”), a private clinical stage company developing therapeutics to reducePhase III study, the riskefficacy and recurrencesafety of cancer and rare diseases, for athe combination of stockeflornithine and future milestone payments. The combined entity will have an expanded pipeline; areas of initial focus includesulindac known as Flynpovi, as compared with either drug eflornithine or sulindac alone, in adults with familial adenomatous polyposis (FAP)(“FAP”) was conducted. A total of 171 patients underwent randomization. Disease progression occurred in 18 of 56 patients (32%) in the Flynpovi group, 22 of 58 (38%) in the sulindac group, and 23 of 57 (40%) in the eflornithine group, with a hazard ratio of 0.71 (95% confidence interval [CI], first-line metastatic pancreatic0.39 to 1.32) for Flynpovi as compared with sulindac (p = 0.29) and 0.66 (95% CI, 0.36 to 1.23) for Flynpovi as compared with eflornithine. In a post-hoc analysis, none of the patients in the Flynpovi arm progressed to a need for lower gastrointestinal (“LGI”) surgery for up to 48 months compared with 7 (13.2%) and 8 (15.7%) patients in the sulindac and eflornithine (CPP-1X) arms. These data corresponded to risk reductions for the need for LGI surgery approaching 100% between Flynpovi and either monotherapy with HR = 0.00 (95% CI, 0.00–0.48; p = 0.005) for Flynpovi versus sulindac and HR = 0.00 (95% CI, 0.00–0.44; p = 0.003) for Flynpovi versus eflornithine. Given the statistical significance of the LGI group, a new drug application (“NDA”) was filed with the FDA. As the study failed to meet the primary endpoint, and the NDA was based on the results of an exploratory analysis, a complete response letter was issued. To address this deficiency concern, the Company must submit the results of one or more adequate and well-controlled clinical trials which demonstrate an effect on a clinical endpoint.

In April of 2023 the Company regained the North American rights to develop and commercialize Flynpovi in patients with FAP, as a result of the termination of the licensing agreement between CPP and One-Two Therapeutics Assets Limited

We also have an ongoing double-blind placebo-controlled trial of Flynpovi to prevent recurrence of high-risk adenomas and second primary colorectal cancers in patients with stage 0-III colon or rectal cancer, neoadjuvant pancreatic cancer,Phase III - Preventing Adenomas of the Colon with Eflornithine and Sulindac (“PACES”). The purpose of this study is to assess whether the combination of eflornithine and sulindac (compared to corresponding placebos) has efficacy against colorectal cancer prevention and ovarian cancer.lesions with respect to high-grade dysplasia, adenomas with villous features, adenomas one cm or greater, multiple adenomas, any adenomas >/= 0.3 cm, total advanced colorectal events, or total colorectal events.

Eflornithine (CPP-1X)/eflornithine sachets (CPP-1X-S)

In 2009 and 2018, the FDA accepted our IND applications for eflornithine.

There are trials evaluating eflornithine sachets in relapsed refractory neuroblastoma supported by the Children’s Oncology Group (“COG”) /NCI (ongoing) and STK11 mutation patients with non-small cell lung cancer scheduled to approval ofbegin this year. For eflornithine tablets, a Phase II trial in early onset Type I diabetes was opened on January 11, 2023 in collaboration with Indiana University and the issuance of securities in the transactions by Panbela’s stockholders, and satisfaction of other customary closing conditions. If approved, the closing is expected to occur in the second quarter of 2022.Juvenile Diabetes Research Foundation (“JDRF”).

 

Financial Overview

On January 13, 2023, the Company's Board of Directors approved the implementation of a reverse stock split at a ratio of one-for-forty (1:40) shares of the Company's common stock. The reverse stock split was effective as of January 13, 2023. All share and per share amounts of our common stock presented have been retroactively adjusted to reflect the one-for-forty reverse stock split.

 

We have incurred losses of $59.8$96.2 million since 2011. For the three months ended March 31, 2022,2023, we incurred a net loss of $3.7$5.1 million. We also incurred negative cash flows from operating activities of approximately $4.5$9.7 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 cash was approximately $7.4$5.2 million and $11.9$1.3 million as of March 31, 20222023 and December 31, 2021,2022, respectively. A decreaseAn increase of $4.5$3.9 million in cash for the three months ended March 31, 20222023 was due to $13.7 million net financing activities offset in part by approximately $9.7 million negative cash flow from operationsoperations. Due to drug shortages of Abraxane, which included $2.6 millionis utilized in addition to fund long term deposits held byivospemin for the CRO leading our randomized trial. This cash balance is expected, due to the increased spending on our newcurrent randomized clinical trial, the Company has explored all avenues to be sufficient to sustain operations intoprocure supply and prepayments of approximately $2.0 million were required well in advance of delivery and is reflected in the fourth quarterperiods cash used in operations. Net financing activities included a registered public offering of 2022.common stock, prefunded warrants, and warrants with net proceeds of approximately $13.7 million. The Company also sold common stock through its at-the market sales arrangement, with net proceeds of approximately $1.6 million. In the same period, the Company also recorded $1.6 million in loan repayments.

 

We will need to raise additional capital to continue our operations and execute our business plan past the fourthsecond quarter of 2022,2023, including completing required future trials and pursuing regulatory approvals in the United States, the European Union, and other international markets. We historicallyHistorically we 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 we are likely to seek additional financing through similar 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 not positive or if economic or market conditions deteriorate.

 

16

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 development of our SBP-101 product candidate, licensecandidates, licensing to third parties the rights to commercialize our SBP-101 product candidate for pancreatic cancercandidates, 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 result 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. DrugThe drug product was delayed induring 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 COVID-19 pandemic.

Cash Flows

 

Net Cash Used in Operating Activities

 

Net cash used in operating activities was approximately $9.7 million in the three months ended March 31, 2023 compared to approximately $4.5 million in the three months ended March 31, 2022 compared to approximately $2.0 million in the three months ended March 31, 2021.2022. 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. For the quarter ended March 31, 2022,2023, cash used in operating activities also included $2.6$5.5 million to fund long term deposits held by the CRO leading our randomized trial. The increase in the quarter to Net Deposits held by our CRO was offset by an increase in Accounts Payable. Also reflected in the increased cash used in operations is approximately $2.0 for prepayment of drug supply.

Net Cash Provided by Financing Activities

 

NoNet cash provided by financing activities was approximately $13.7 million for the three months ended March 31, 2023, with no cash provided by financing activities for the three months ended March 31, 2022 and net cash provided by financing activities was approximately $1.0 million for the three months ended March 31, 2021.2022. The cash provided for the three months ended March 31, 20212023 represents the proceeds from the exercisesale of common stock, prefunded warrants duringand warrants, partially offset by the quarter.payment and payoff of promissory notes.

 

Capital Requirements

 

As we continue to pursue our operations and execute our business plan, including wrapping up our current Phase 1the completion of the clinical trialdevelopment plan for our initial product candidate, SBP-101,ivospemin, 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.

16

 

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

 

 

the progress of clinical trials required to support our applications for regulatory approvals, including the completion of our Phase Ia /Ib clinical trial, a human clinical trial in Australia and the United States and a global, randomized Phase II/III trial initiated in January of 2022;

 

 

the impact of the current COVID-19 pandemic on our ability to initiate enrollment in a future clinical trial and to monitor our current clinical trial;

the cost to implement development efforts for SBP-101ivospemin in ovarian cancer and expand development efforts for assets acquired as the result of the acquisition of CPP;

 

 

the cost, if any, to develop our product candidate, Flynpovi;

the cost to develop eflornithine in various indications if early clinical trials underway now, and funded through third party collaborations, are successful;

our ability to demonstrate the safety and effectiveness of our SBP-101 product candidate;candidates;

 

 

our ability to obtain regulatory approval of our SBP-101 product candidatecandidates in the United States, the European Union or other international markets;

 

 

the cost and delays in product development that may result from changes in regulatory oversight applicable to our SBP-101 product candidate;candidates;

 

 

the market acceptance and level of future sales of our SBP-101 product candidate;candidates;

 

 

the rate of progress in establishing reimbursement arrangements with third-party payors;

 

 

the effect of competing technological and market developments; and

 

 

the costs involved in filing and prosecuting patent applications and enforcing or defending patent claims.

 

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 March 31, 2022,2023, we did not have any existing credit facilities under which we could borrow funds.

We will need to obtain additional funds to continue Historically we have financed our operations principally from the sale of equity securities 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.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 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 staff compensation, significantly modifying or delaying the development of , licensing rights to third parties, including the right to commercialize 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.

Accrued and unpaid interest as of March 31, 2023 totaled approximately $42,000.

Panbela has provided a Guarantee of payment in favor of the Lender for the full amount of the Note issued to the Lender.

As of March 31, 2022 and December 31, 2021 we had no debt obligations.2023, the outstanding balance on the amended promissory note with a former development partner, Tillotts Pharma AG was paid in full.

 

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 20222023 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, 2021.2022.

 

Item 3.

Quantitative and Qualitative DisclosureDisclosures About Market Risk.

 

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

 

Item 4.

Controls and Procedures.

 

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 March 31, 2022,2023, 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.

Risk Factors.

 

ThereOther than noted below there 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, 2021.2022.

 

We could be delisted from Nasdaq, which would seriously harm the liquidity of our stock and our ability to raise capital.

During the first quarter of 2023, we cured previously identified minimum bid price and minimum stockholders’ equity deficiencies and regained compliance with all applicable listing standards of The Nasdaq Stock Market LLC (“Nasdaq”). However, on April 14, 2023, we received a notification letter from the Listing Qualifications Department (the “Staff”) of Nasdaq indicating that for 30 business days, our common stock did not maintain a minimum closing bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2) (“Minimum Bid Price Requirement”). The Nasdaq notification has no immediate effect on the listing or trading of our common stock on Nasdaq. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), we have an initial compliance period of 180 calendar days, or until October 11, 2023, to regain compliance with the Minimum Bid Price Requirement. During the compliance period, our shares of common stock will continue to be listed and traded on The Nasdaq Capital Market. To regain compliance, the closing bid price of our common stock must meet or exceed $1.00 per share for a minimum of ten consecutive business days or such longer period as may be required in the Staff’s discretion during the 180-calendar day grace period. Further, if our common stock has a closing bid price of $0.10 or less for ten consecutive business days, then the Staff may proceed with immediate delisting, subject to a limited opportunity for a hearing.

We intend to take all reasonable measures available to regain compliance under the Nasdaq Listing Rules and remain listed on Nasdaq, including by effecting a reverse stock split. At our annual meeting of stockholders to be held on May 25, 2023, we are asking stockholders to approve a proposed amendment to our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our outstanding common stock at a reverse stock split ratio ranging from any whole number between 1-for-5 and 1-for-100, subject to and as determined by our Board of Directors. If the reverse stock split proposal is not approved by our stockholders, then we will be unable to complete a reverse stock split, and our common stock will be delisted from the Nasdaq Capital Market if our bid price does not improve. Even if a reverse stock split is approved and effected, it is not a guarantee that we will ultimately regain compliance with the applicable requirements for continued listing.

If, for any reason, Nasdaq were to delist our securities from trading on The Nasdaq Capital Market and we were unable to obtain listing on another reputable national securities exchange, a reduction in some or all of the following may occur, each of which could materially adversely affect our stockholders:

the liquidity and marketability of our common stock;

the market price of our common stock;

our ability to obtain financing for the continuation of our operations;

the number of institutional and general investors that will consider investing in our common stock;

the number of market makers in our common stock;

the availability of information concerning the trading prices and volume of our common stock; and

the number of broker-dealers willing to execute trades in shares of our common stock.

In addition, if we cease to be listed on The Nasdaq Capital Market, we may have to pursue trading on a less recognized or accepted market, such as the over the counter markets, our stock may be traded as a “penny stock”, which would make transactions in our stock more difficult and cumbersome, and we may be unable to access capital on favorable terms or at all, as companies trading on alternative markets may be viewed as less attractive investments with higher associated risks, such that existing or prospective institutional investors may be less interested in, or prohibited from, investing in our common stock. This may also cause the market price of our common stock to further decline.
