Notes to the Unaudited Condensed Consolidated Financial Statements
(unaudited)
 
1. Nature of Business and Liquidity
 
The terms "MBI" or "the Company", "we", "our", and "us" are used herein to refer to Moleculin Biotech, Inc. MBI is a clinical-stage pharmaceutical company, organized as a Delaware corporation in July 2015, with its focus on the treatment of highly resistant cancers via the development of its oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D.MD Anderson Cancer Center, which we refer to as MD Anderson. MBI formed Moleculin Australia Pty. Ltd., (MAPL), a wholly-ownedwholly owned subsidiary in June 2018, to begin preclinical development in Australia for WP1732, an analog of WP1066. This may enableenables the Company to enjoy the benefits of certain research and development tax credits in Australia. In February 2019, the Company entered into an agreement with Animal Life Sciences, LLC ("ALI")(ALI), where the Company has granted a sublicense to ALI to research, develop, make, have made, use, offer to sell, sell, export or import and commercialize certain licensed products for non-human use and share development data. ALI issued to the Company a 10% interest in ALI. ALI converted into a corporation and became Animal Life Sciences, Inc.

Core Technologies - MBI has three3 core technologies with six6 drug candidates, all of which are based on discoveries made at MD Anderson. These core technologies are 1) Annamycin, 2) its STAT3 Immune/Transcription Modulators, or simply "Immune/Transcription Modulators", WP1066 portfolio and 3) its Metabolism/Glycosylation Inhibitor portfolio.portfolio, WP1122. The Company’s clinical stage drugs are Annamycin, an anthracycline being studiedwhich is in two Phase 1/2 studies for the treatment of relapsed or refractory acute myeloid leukemia, or AML and(AML), WP1066, an Immune/Transcription Modulator, targeting brain tumors, pancreatic cancerwhich is in a Phase 1 clinical trial in the United States of America (US) for the treatment in glioblastoma, and AML. WP1220, an analoga member of the WP1066 had its Clinical Trial Application ("CTA")portfolio of drugs, which has completed a Phase 1 proof-of-concept clinical trial for the topical treatment of cutaneous T-cell lymphoma ("CTCL")(CTCL), a form of skin cancer, approved by Polish regulators in January 2019 with the first patients enrolled in March 2019. MBI is also engaged in preclinical development of additional drug candidates, including other Immune/Transcription Modulators, as well as Metabolism/Glycosylation Inhibitors. With the approval of the Polish clinicalcancer. A fifth Phase 1 trial in January 2019 for WP1220 for the treatment of CTCL,pediatric brain tumors at Emory University has been approved by the Company now has three drugsUS Food and Drug Administration (FDA) and began recruiting patients in four clinical trials.2020.

The Company believes Annamycin is a "Next Generation Anthracycline" since it is designed to avoid the multidrug resistance mechanisms that typically defeat currently approved anthracyclines, andas well as to produce little to no cardiotoxicity,be non-cardiotoxic, which is the dose limiting toxicity of all currently approved anthracyclines. Annamycin is currently in two Phase I/II1/2 clinical trials, and preliminary clinical data suggests that it may have the potential to become the first therapy suitable for the majority of relapsed or refractory AML patients.patients regardless of gene mutations. During 2019, these trials have so far demonstrated the safety, including no cardiotoxicity, and has begun to show some initial efficacy. Additionally, preclinical research in animal models at MD Anderson demonstrated that Annamycin is able to significantly improve survival in an aggressive form of triple negative breast cancer metastasized to the lungs. Coupled with research demonstrating that Annamycin is capable of accumulating in the lungs at high levels, this suggests that Annamycin may be well suited to become a treatment for lung-localized tumors.

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

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

Drug Candidates - Within the Company's core technologies, it currently has six6 drug candidates representing three3 substantially different approaches to treating cancer. Annamycin is a chemotherapy designed to inhibit the replication of DNA of rapidly dividing cells and is the Company's most mature drug candidate. Annamycin had been in clinical trials pursuant to an investigational new drug application or IND that had been filed with the U.S. Food and Drug Administration, or FDA. Due to a lack of development activity by a prior drug developer, this IND was terminated. To permit the renewed investigation of Annamycin, the Company resubmitted a new IND for a Phase I/II trial for the treatment of relapsed or refractory AML in August 2017, which the FDA allowed to go into effect in September 2017. The Company has trials open in the US and Poland. The US Phase 1 portion of the Phase 1/2 trial reached key safety end points in early 2020 and the Company plans to discuss next steps with the FDA. The Phase 1/2 trial in Poland continues its dose escalation and is actively recruiting in its fifth cohort. So far both countries.trials have proven Annamycin, to date, is safe and is non-cardiotoxic. The trials have demonstrated initial efficacy as well.

TheIn addition to Annamycin, the Company has five other drug development projects, some2 of which are also in clinical trials:

WP1066 has an approved physician-sponsored clinical trial open for enrollment and dosing patients for the treatment of brain tumors and is also being evaluateda second physician-sponsored Phase 1 trial for the potential treatment of pediatric brain tumors as well as AML and pancreatic cancer,has begun recruitment.

WP1220 is an analog of WP1066 for which Polish authorities approved the Company filed aCompany's Clinical Trial Application ("CTA")(CTA) in Poland2019 for a Phase 1 "proof-of-concept" clinical trial to study the topical treatment of CTCL, whichCTCL. This trial was approved in January 2019,completed and forthe Company believes it demonstrated sufficient efficacy to justify a Phase 2 trial, which the first patients were enrolledCompany expects to prepare for in March 2019,the near future.

WP1732,WP1066 along with another analog, of WP1066 that the Company believes is particularly well suited for intravenous administration, isWP1732, are being evaluated for the potential treatment of AML, pancreatic and other cancers, andcancers. MBI has begun pre-clinical work that it expects to generate sufficient data for an IND filing in 2019,for an intravenous formulation of one of its STAT3 inhibitors, which filing is expected to be submitted in 2020, and2021.

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

Clinical Trials - The Company believes that patient recruitment forhas concluded the initial Phase 1 portion of its Annamycin clinicalPhase 1/2 trial in the US has been slow due to the high number of competitive clinical trials, combined with the FDA’s requirement to set the initial dose level relatively low in comparison with previous Annamycin clinical trials. Additionally, the Company believes that patient recruitment for its clinical trial in Poland has beenwill continue to be more successful than in the US due to a comparatively lower number of competitive clinical trials and the protocol there being approved to start at a significantly higher dose than in the US with fewer enrollment screening limitations.

This trial is in its fifth cohort in the dose ranging Phase 1 portion of the trial. In MaySeptember 2018, the Company engaged another contract research organization ("CRO") to evaluate additional countries for the expansion of its AML clinical trial, specifically Australia and several Western European countries to provide additional clinical sites to improve access to patients for MBI's trial. This evaluation is ongoing.

In July 2018, the physician-sponsoredphysician sponsored WP1066 Phase I clinical trial for the treatment of glioblastoma and melanoma metastasized to the brain, which opened for recruitment andin July 2018, began treating patients in September 2018.

patients. In September 2017,April 2020, a second Phase 1 trial for another physician-sponsored clinical trial for the potential treatment of pediatric brain tumors began recruitment of patients. In August 2019, the Company engaged a CRO to prepare for acompleted its proof-of-concept Phase 1 clinical trial in Poland to study its drug candidate WP1220, a part of the WP1066 portfolio, for the treatment of CTCL. The Company subsequently filed a CTA in Poland for this use, which was approved subsequent to December 31, 2018,This trial demonstrated the safety of WP1220 and gavealso demonstrated, the Company its third drugbelieves, initial efficacy sufficient for a Phase 2 trial, which the Company expects to prepare for in its fourth clinical trial. This trial began enrolling patients in March 2019.the near future.

Licenses - The Company has been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all of MBI's drug technologies, as these intellectual property rights are owned in part or entirely by MD Anderson. The Annamycin drug substance is no longer covered by any existing patent protection, however, the Company filed new patent applications in July 2019 for formulation, synthetic process and reconstitution related to MBI's Annamycin drug product candidate, although there is no assurance that the Company will be successful in obtaining such patent protection. Such technology is also licensed from MD Anderson. Independently from potential patent protection, MBI has received Orphan Drug designation ("ODD")(ODD) from the FDA for Annamycin for the treatment of AML and for WP1066 for the treatment of glioblastoma. ODD may provide tax and other benefits during product development, and if either product is approved, may lead to a grant of seven-yearseven-year market exclusivity. Under that exclusivity, which runs from the date of the approval of the New Drug Application ("NDA")(NDA) in the United States,US, the FDA generally (there are important exceptions) could not approve another product containing the same drug for the designated indication. The Company also intends to apply for similar status in the European Union ("EU")(EU) where market exclusivity could extend to 10 years from the date of Marketing Authorization Application ("MAA")(MAA) approval. Separately, the FDA may also grant market exclusivity of 5 years for newly approved new chemical entities (which the Company believes Annamycin would be one), which would preclude approval of any other annamycin product, but there can be no assurance that such exclusivity will be granted. In April 2019, FDA approved the Company's request for Fast Track Designation for Annamycin for the treatment of relapsed or refractory AML. Fast Track Designation, the purpose of which is to expedite drug development and approval, is granted to drugs intended to treat serious conditions and where data demonstrate the potential to address an unmet medical need.

Moleculin, LLC -COVID 19 Prior- In March 2020, the World Health Organization declared the outbreak of a novel Coronavirus (COVID-19) as a pandemic, which continues to MBI's initial public offering,spread throughout the US. The spread of COVID-19 has caused significant volatility in US and international markets, including Poland, where the Company acquired Moleculin, LLCconducts some of its clinical trials and Italy, where its drug supply is produced. There has been limited interruption of the Company’s drug supply, and some Polish clinics where the Company is conducting trials have limited access on monitoring activities, which was merged withfor now has not materially slowed the progress of our trials. This could change at any time. Furthermore, there is significant uncertainty around the breadth and into MBI. Moleculin, LLC was the holder

Nasdaq - On April 23, 2020, the Company received a letter from NASDAQ notifying the Company that it had regained compliance with NASDAQ Listing Rule 5550(a)(2) as a result of key oncogenic transcription factors.the closing bid price of the Company's common stock being at $1.00 per share or greater for the 10 consecutive business days from April 8, 2020 through April 22, 2020. Accordingly, the Company is in compliance with the Bid Price Rule and NASDAQ considers the matter closed.


2. Basis of presentation, principles of consolidation and significant accounting policies
 
Basis of Presentation – Unaudited Interim Condensed Consolidated Financial Information - The accompanying unaudited interim condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”)US (U.S. GAAP) for financial information, and in accordance with the rules and regulations of the United StatesUS Securities and Exchange Commission (the “SEC”)(SEC) with respect to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements furnished
8


reflect all adjustments (consisting of normal recurring adjustments), which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These interim condensed unaudited consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of December 31, 20182019 and December 31, 20172018 and notes thereto contained in the Form 10-K filed with the SEC on February 21, 2019.March 19, 2020.
 
Principles of consolidation - The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-ownedwholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP. The company views its operations and manages its business in one1 operating segment. All long-lived assets of the Company reside in the United States.US.

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

Going Concern - These condensed consolidated financial statements have been prepared on a going concern basis, which assumes the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The continuation of the Company as a going concern is dependent upon the ability of the Company to obtain necessary equity financing to continue operations and the attainment of profitable operations. As of June 30, 2019,March 31, 2020, the Company has incurred an accumulated deficit of $31.6$40.8 million since inception and had not yet generated any revenue from operations. Additionally, management anticipates that its cash on hand as of June 30, 2019,March 31, 2020, is sufficient to fund its planned operations into but not beyond the near term. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. These unaudited condensed consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. Management cannot be certain that such events or a combination thereof can be achieved.

On May 1, 2020, the SEC pursuant to Section 12(k) of the Securities Exchange Act of 1934, as amended, ordered the temporary suspension of trading in the securities of the Company because of questions regarding the accuracy and adequacy of information in the marketplace about the Company and its securities. Pursuant to the suspension order, the suspension
9


commenced on May 4, 2020 and terminates on May 15, 2020. As of the date of this report, the Company has submitted a petition to terminate the suspension, but there is no assurance that the Company will be successful. The Company believes it will be able to demonstrate the accuracy and adequacy of its public disclosures, but the SEC may determine to extend the trading suspension until such time that it believes the information in the marketplace about the Company and its securities is accurate and adequate.
 
Cash and Cash Equivalents - The Company considers all highly liquid accounts with original maturities of three months or less at the date of acquisition to be cash equivalents. Periodically in the ordinary course of business, the Company may carry cash balances at financial institutions in excess of the Federally insured limits of $250,000.

Prepaid Expenses and Other Current Assets - Prepaid expenses and other current assets consist of the following (in thousands):
March 31, 2020December 31, 2019
Vendor prepayments and deposits$1,372  $1,857  
Prepaid insurance150  352  
Non-trade receivables  
Related party receivables—  10  
Other current assets615  529  
Total prepaid expenses and other current assets$2,138  $2,749  

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

Intangible assetsAssets - Intangible assets with finite lives are amortized using the straight-line method over their estimated period of benefit. If anAcquired intangible asset isassets identified as an in-process research &and development ("IPR&D") asset, then no amortization will occur(IPR&D) assets, are considered indefinite lived until the completion or abandonment of the associated research and development is complete.efforts. If the associated research and development effort is abandoned, the related IPR&D assets will be written-off and the Company will record a noncash impairment loss on its statements of operations. For those compounds that reach commercialization, if any, the IPR&D assets will be amortized over their estimated useful lives.

The Company evaluates the recoverability of intangible assets periodically and takestake into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. No materialNaN impairments of intangible assets have been identified during any of the periods presented. Intangible assets are tested for impairment on an annual basis, and between annual tests if the Company believes indicators of potential impairment exist, using a fair-value-based approach.

Property and Equipment, net - Leasehold improvements, furniture, equipment and software are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. Accumulated depreciation on property and equipment was $0.2$0.3 million at June 30, 2019,March 31, 2020, and $0.1 million at December 31, 2018.2019, respectively.

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

Cost Method Investment - The Company's cost method investment consists of an investment in a corporation in which it does not have the ability to exercise significant influence over its operating and financial activities. Management evaluates this investment for possible impairment quarterly.
Fair Value of Financial Instruments - The Company's financial instruments consist primarily of non-trade receivables, account payables, accrued expenses and aits warrant liability. The carrying amount of non-trade receivables, accounts payables, and accrued expenses approximates their fair value because of the short-term maturity of such.
 
The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).
 
Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:
 
Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.
Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3 – Unobservable inputs for the asset or liability.
 
The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of warrant liability discussed in Note 4. In the accompanying interim condensed consolidated financial statements as of June 30, 2019, the fair value of this warrant liability is included in current liabilities for the February 2017 Issuance of Warrants, the February 2018 Issuance of Warrants, the June 2018 Issuance of Warrants, the March 2019 Issuance of Warrants, and the April 2019 Issuance of Warrants. Warrant liabilities will be shown as a current liability on the balance sheet when it is deemed more probable than not by management to be exercised within one year.

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. For purposes of this calculation, options to purchase common stock, restricted stock units subject to vesting and warrants to purchase common stock are considered to be common stock equivalents. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive. The Company’s potentially dilutive securities, which were not included in the calculation of net loss per share as inclusion of these securities would have been anti-dilutive are summarized in the table below:

June 30,
20192018
Warrants2,814,000 3,784,515 
Stock options10,613,998 2,754,000 
Total Common Stock Equivalents13,427,998 6,538,515 

Reclassifications - A reclassification was made to the prior period financial statements to conform to the 2019 presentation. Such reclassification did not affect net loss as previously reported. Historically, "Deferred compensation - related party" was a separate line item on the balance sheet. Management believes that this balance is best shown included in "accrued expenses and other current liabilities," and, as such, a reclassification was made to the balance sheet for the period ended December 31, 2018 to include "deferred compensation - related party" in with "accrued liabilities and other current liabilities." Additionally, interim disclosures pertaining to stockholders' equity are shown for current and comparative year-to-date periods, with subtotals for each interim period.

equivalents, because their inclusion would be antidilutive. For the three months ended March 31, 2020 and 2019, approximately 18.4 million and approximately 6.7 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to their antidilutive effect.

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

Recent Accounting Pronouncements
 
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. In July 2018, the FASB issued ASU No. 2018-11, Leases Targeted Improvements ("ASU 2018-11"). In March 2019, the FASB issued ASU. No. 2019-01, Leases ("ASU 2019-01"). ASU 2019-01 and 2018-11 assists stakeholders with implementation questions and issues as organizations prepare to adopt the new leases standard. The Company adopted this standard on January 1, 2019 and used the effective date of initial application using the modified retrospective transition method. Upon adoption there was no cumulative-effect adjustment to the opening balance of retained earnings as of January 1, 2019. Therefore, prior period financial information has not been adjusted and continues to be reflected in accordance with the Company's historical accounting policy. The standard establishes a ROU asset model that requires the lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. (see Note 7. Commitments and Contingencies - Lease Obligations Payable).
In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718) Improvements to Non-employee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 affects all entities that enter into share-based payment transactions for acquiring goods and services from non-employees. The amendments in this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption permitted, but no earlier than an entity's adoption date of Topic 606. The adoption of this pronouncement did not have a material impact on the Company's condensed consolidated financial statements.

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

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) (ASU 2019-12). ASU 2019-12 modifies the requirements for the timing of adoption of enacted change in tax law. The effects of changes on taxes currently payable or refundable for the current year must be reflected in the computation of annual effective tax rate in the first interim period that includes the enactment date of the new legislation, beginning after December 15, 2020. Early adoption is permitted upon issuance of this ASU. The Company is currently evaluating the impact that this standard will have, if any, on its financial statements.

The Company does not believe that any other recently issued effective pronouncements, or pronouncements issued but not yet effective, if adopted, would have a material effect on the accompanying condensed consolidated financial statements.

Liability Classified Warrants

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

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

Estimated volatility is a measure of the amount by which the Company's stock price is expected to fluctuate each year during the expected life of the warrants. Where appropriate,Beginning in 2020, only the volatility of the Company's own stock is used in the BSM as it now has sufficient historic data in its stock price. In 2019, the Company used the historicalvolatility of its own stock blended with the volatility of peer entities combined with the Company's due to the lack of sufficient historical data of itsour stock price during the years 2017 to 2019.price.

There were 45,000 options granted during the six months ended June 30, 2019. Options granted during 2019 have an aggregated fair value of $0.04 million that was calculated using the Black-Scholes option-pricing model. As of June 30, 2019, total compensation cost not yet recognized was $2.6 million and the weighted average period over which this amount is expected to be recognized is 2.28 years.

The fair value of each stock option is estimated on the date ofCompany did not grant using the Black-Scholes option valuation model that uses the assumptions noted in the above paragraph and table. The expected term of the options was computed using the "plain vanilla" method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin 107 because the

Company does not have sufficient data regarding employee exercise behavior to estimate the expected term. The volatility was determined by referring to the average historical volatility of a peer group of public companies combined with the Company's due to the lack of sufficient historical data of its stock price. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

Consulting Agreement

In 2017, the Company entered into a consulting agreement for its investor relations operations. The consulting agreement initially covered a period of twelve months from the commencement date of July 29, 2017, was extended in April 2018 until March 31, 2019. Pursuant to the original consulting agreement, in exchange for the consulting services, the Company issued two warrants (collectively, the “Warrants”) to purchase 100,000 and 50,000 shares of common stock at exercise prices of $2.41 and $3.00 per share. Each of the Warrants vested over a 12-month period in equal monthly installments starting July 29, 2017, provided that the consultant was providing services to the Company pursuant to the consulting agreement on each vesting date. The Warrants became initially exercisable on August 8, 2017 and expire five years from the initial exercise date. The Company recorded stock compensation expense for the non-employee consulting agreement of $0.00 million and $0.04 million forany stock-based awards during the three months ended June 30, 2019 and 2018, respectively, and $0.002 million and $0.1 million during the six months ended June 30, 2019 and 2018, respectively.

The Company believes the issuance would be exempt from registration under the Securities Act in reliance on Section 4(a)(2) of the Securities Act regarding transactions not involving a public offering. On August 8, 2019, the Company elected to issue such warrant with an exercise price of $1.64.

6. Income Taxes
 
Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company does not expect to pay any significant federal, state, or foreign income taxes in 20192020 as a result of the losses recorded during the three and six months ended June 30, 2019March 31, 2020 and the additional losses expected for the remainder of 20192020 and cumulative net operating loss carryforwards. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all of the benefits of deferred tax assets will not be realized. As a result, as of June 30, 2019,March 31, 2020, the Company maintained a full valuation allowance for all deferred tax assets.
 
The Company recorded no0 income tax provision for the three and six months ended June 30,March 31, 2020 and 2019, and 2018.respectively. The effective tax rate for the three and six months ended June 30,March 31, 2020 and 2019 and 2018 wasis 0%. The income tax rates vary from the federal and state statutory rates primarily due to the change in fair value of the stock warrants and valuation allowances on the Company’s deferred tax assets. The Company estimates its annual effective tax rate at the end of each quarterly period. Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation allowance could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.

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

The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses an incremental borrowing rate based on a peer analysis using information available at the commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment. During the six months ended June 30, 2019, other than the initial adoption of the lease standard that required right of use assets and lease liabilities to be recorded, there were no right of use assets recorded arising from new lease liabilities.Licenses

Total expenses under these agreements were $0.1 million and $0.1 million$60,000 for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively, and $0.1 million and $0.2 million during the six months ended June 30, 2019 and 2018, respectively.

HPI - On June 29, 2017,March 16, 2020, the Company entered into an2 agreements with a related party, Houston Pharmaceuticals, Inc.(HPI). The first agreement, which has a term of two years, continues a prior consulting arrangement with MD Anderson licensing certain technology related toHPI on the method of preparing Liposomal Annamycin.

WP1122 Portfolio

The rightsCompany's licensed molecules and obligations to an April 2012 Patent and Technology License Agreement entered into by and between IntertechBio and MD Anderson (the “IntertechBio Agreement”) have been assigned to MBI. Therefore, MBI has obtained a royalty-bearing, worldwide, exclusive license to intellectual property, including patent rights, related to our WP1122 Portfolio and to our drug product candidate, WP1122.

WP1066 Portfolio
The rights and obligations to a June 2010 Patent and Technology License Agreement entered into by and between Moleculin LLC and MD Anderson (the “Moleculin Agreement”) have been assigned to MBI. Therefore, MBI has obtained a royalty-bearing, worldwide, exclusive license to intellectual property rights, including patent rights, related to our WP1066 drug product candidate. In consideration, MBI must make payments to MD Anderson including an up-front payment, milestone payments and minimum annual royaltyrequires payments for sales of products developed under$43,500 per quarter to HPI. The second agreement, which can be cancelled with sixty days' notice by either party, allows the license agreement. Annual Maintenance fee payments will no longer be due upon marketing approval in any country of a licensed product. One-time milestone payments are due upon commencement of the first Phase III studyCompany's employees access to laboratory equipment owned by HPI for a licensed product within the United States,

Europe, China or Japan; upon submissionpayment of the first NDA for a licensed product in the United States; and upon receipt of the first marketing approval for sale of a licensed product in the United States. The rights the Company has obtained pursuant$15,000 per quarter to the assignment of the Moleculin Agreement are made subject to the rights of the U.S. government to the extent that the technology covered by the licensed intellectual property was developed under a funding agreement between MD Anderson and the U.S. government.

MBI entered into an out-licensing agreement with Houston Pharmaceuticals, Inc. (“HPI”), pursuant to which it granted certain intellectual property rights to HPI, including rights covering the potential drug candidate, WP1066 (“HPI Out-Licensing Agreement”). Under the HPI Out-Licensing Agreement the Company was required to make quarterly sponsored research payments totaling $0.75 million for the first twelve quarters following the effective date, of the HPI Out-Licensing Agreement, or May 2, 2016, in consideration for the right to development data related to the development of licensed products. Notwithstanding the Company's obligation to make the foregoing payments, the HPI Out-Licensing Agreement did not obligate HPI to conduct any research or to meet any milestones. Upon payment in the amount of $1.0 million to HPI within three years of the effective date of the HPI Out-Licensing Agreement ("HPI Option Repurchase Payment") MBI regained all rights to the licensed subject matter and rights to any and all development data and any regulatory submissions including any IND, NDA or ANDA related to the licensed subject matter and can end the license without any other obligation other than the aforementioned quarterly sponsored research payments. The option repurchase payment was paid on April 30, 2019 for $1.0 million and, accordingly, the HPI Out-Licensing Agreement was terminated. The $1.0 million payment was accrued and expensed under "Research and development" in the second quarter of 2018.HPI. Total expenses related to the Company's agreements with HPI were $0.0 million$207,500 and $1.1 million$75,000 for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively, and $0.1 million and $1.2 million for the six months ended June 30, 2019 and 2018, respectively.

In February 2018, MBI entered into a license agreement with MD Anderson covering a new group of molecules recently discovered in connection with research it has been sponsoring there called WP1732, a part of the WP1066 Portfolio.

sublicense agreements. In July 2019, Dermin assigned its rights under the foregoing license agreements to an affiliated entity, Exploration Invest Pte Ltd. (“Exploration”). On July 30, 2019, the Company and Exploration entered into a License Modification Agreement pursuant to which the Company agreed to issue Exploration shares of Company common stock valued at $0.5 million (based on the greater of the closing price of the common stock on the date of the agreement or the 10-day average closing price prior to the date of the agreement) in exchange for the modifying the license agreements to: (i) limit the licensed territory solely to Poland; and (ii) limit the patent rights and technology rights licensed to Exploration to the patent rights and technology rights that existed on the date the original license agreements were entered into with Dermin.

WPD Pharmaceuticals

On February 19, 2019, the Company sublicensed certain intellectual property rights, including rights to Annamycin, its WP1122 portfolio, and its WP1066 portfolio to WPD Pharmaceuticals (“WPD”) (the “WPD Agreement”). WPD is affiliated with Dr. Waldemar Priebe, one of the Company's founders and largest shareholder. Under the WPD Agreement, the Company granted WPD a royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell products in the field of human therapeutics under the licensed intellectual property in the countries of Germany, Poland, Estonia, Latvia, Lithuania, Belarus, Ukraine, Moldova, Romania, Armenia, Azerbaijan, Georgia, Slovakia, Czech Republic, Hungary, Uzbekistan, Kazakhstan, Greece, Austria, Russia, Netherlands, Turkey, Belgium, Switzerland, Sweden, Portugal, Norway, Denmark, Ireland, Finland, Luxembourg, Iceland (“licensed territories”), provided that the Company has the right to buyback Germany from the licensed territories by making a payment $0.5 million. On July 30, 2019, the Company entered into an agreement that satisfied the foregoing buyback right, and as such, Germany is no longer considered part of the licensed territories.

In consideration for entering into the WPD Agreement, WPD agreed that it must use Commercially Reasonable Development Efforts to develop and commercialize products in the licensed territories. For purposes of the WPD Agreement, the term “Commercially Reasonable Development Efforts” means the expenditure by or on behalf of WPD or any of its affiliates of at least: (i) $2.0 million during the first two years of the agreement on the research, development and commercialization of products in the licensed territories; and (ii) $1.0 million annually for the two years thereafter on the research and development of products in the licensed territories. This license is subject to the terms in the prior agreements entered into by the Company with Dermin and MDA.

Prior to approval of the WPD Agreement, the Company's board of directors received a fairness opinion from Roth Capital Partners, LLC that stated that it was their opinion that the consideration the Company will receive from WPD pursuant to the WPD Agreement is fair, from a financial point of view, to the Company.

Animal Life Sciences

On February 19, 2019, the Company sublicensed certain intellectual property rights, including rights to Annamycin, its WP1122 portfolio, and its WP1066 portfolio in the field of non-human animals to ALI (the “ALI Agreement”). ALI is affiliated with Dr. Waldemar Priebe, one of its founders and its largest shareholder. Under the ALI Agreement, the Company granted ALI a worldwide royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell products in the field of non-human animals under the licensed intellectual property. This license is subject to the terms in the prior agreements entered into by the Company and MDA. Under the ALI Agreement, the Company has the right to name an observer to ALI's board of directors. On August 8, 2019, the Company named its Chairman and CEO Walter V. Klemp to that position.

Since ALI and WPD are beginning the process to develop and commercialize products using the sublicensed intellectual property rights, the Company is currently unable to predict whether ALI and WPD will be successful in developing such products or when the Company may recognize royalty revenues related to such products.

Overview

Moleculin Biotech, Inc., a Delaware corporation, is a clinical stage pharmaceutical company focused on the treatment of highly resistant cancers.cancers and viruses. We have three core technologies, all of which are based on discoveries made at M.D. Anderson Cancer Center ("MD Anderson")(MD Anderson). We have three drugsdrug candidates that are active in clinical trials. In 2019, those three drug candidates were active in four clinical trials in the US and Poland. OurEurope with a fifth that began recruiting patients in April 2020. Of these five clinical trials, two are primarily externally funded. For two of our internally funded trials, we successfully concluded the Phase 1 portion recently and are preparing to potentially move into Phase 2 trials. We anticipate laying the groundwork in 2020 for two additional Phase 1 trials expected to begin in 2021 sponsored by us and two other Phase 1 trials we expect to be externally sponsored.

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

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

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

We believe that our Next Generation Anthracycline,consider Annamycin isto be a "next generation" anthracycline, unlike any currently approved anthracyclines, as it is designed to avoid multidrug resistance mechanisms with little to no cardiotoxicity (two problems common to all currently approved anthracyclines) — hence. We recently received an independent expert cardiology assessment confirming the useabsence of cardiotoxicity in the term "Next Generation."first 14 patients treated with Annamycin in both our US and European Phase 1 clinical trials, validating Annamycin's lack of cardiotoxicity. Annamycin is currently in twoone Phase I/II1/2 clinical trials and preliminary clinicaltrial in Europe with the Phase 1 portion of another Phase 1/2 AML trial recently concluding in the US. Upon receipt of further data suggests it may havefrom the potentialEuropean Phase 1 trial, we plan to becomeseek agreement with the first successful therapy suitableFDA for accelerated approval of Annamycin based on a pivotal Phase 2 AML trial sponsored by us, although there is no assurance that the FDA will agree with our proposal.

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

WP1066 is one of several STAT3 Immune/Transcription Modulators designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory T-Cells ("TRegs")TCells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3, c-Myc and HIF-1α. These transcription factors are widely sought targets that may also play a role in the lack of efficacyinability of immune checkpoint inhibitors in certainto affect more resistant tumors. WP1066 is currently in a US physician-sponsored Phase 1 trial for the treatment of glioblastoma ("GBM") and another institutionally sponsored Phase 1 trial has begun recruiting for the treatment of pediatric brain tumors. Another physician-sponsored Phase 1 trial is being considered for the treatment of GBM with WP1066 in combination with radiation, although no assurances can be given that such trial will begin.

21


We are also developing new compounds designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (“2-DG”)2-Deoxy-D-glucose (2-DG), which we believe may provide an opportunity to cut offlimit the fuel supply ofenergy available to tumors and virus host-cells by taking advantage of their high level of dependence on glucose in comparison to healthy cells. A key drawback to 2-DG is its lack of drug-like properties, including a short circulation time and poor tissue/organ distribution characteristics. Our lead Metabolism/Glycosylation Inhibitor, WP1122, is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. New research also points to the potential for 2-DG to be capable of enhancing the usefulness of checkpoint inhibitors.inhibitors and also its potential against viruses like the Coronavirus. Considering that 2-DG lacks sufficient drug-like properties to be practical in a clinical setting, we believe WP1122 may alsohas the potential to become an important drug, either as a single agent or to potentiate existing therapies, including checkpoint inhibitors.

Missioninhibitors and Strategy

Moleculin is focused on developing treatments for highly resistant cancers. These include AML, glioblastoma, cutaneous t-cell lymphoma, pancreatic cancer, and others. Our diverse pipeline of technologies was built around the recognition that many highly resistant tumors tend to have a common set of traits, including an increase in multidrug resistant mechanisms, an evasion of the natural immune system, a marked upregulation of certain key oncogenic transcription factors and an increased dependence on glycolysis for energy production. We believe each of these elements may be addressed by the unique and innovative mechanisms introduced by one or more of our three core technologies.

We believe this approach not only provides the opportunity to help the many patients in need of alternative therapies, but also to work in combination with numerous existing technologies that often fail as tumors present immediate or acquired resistance. We believe showing even modest improvements in highly resistant cancers may lead to accelerated approval pathways, potentially reducing the time and capital required to ultimately realize success.

Corporate Overview

We were founded in 2015 in order to combine and consolidate the development efforts involving several oncology technologies, based on license agreements with MD Anderson. This effort began with the acquisition of the Annamycin development project from AnnaMed, Inc., or AnnaMed, followed by the acquisition of the license rights to the WP1122 Portfolio from IntertechBio Corporation, or IntertechBio. Further, on behalf of Moleculin, LLC,antiviral treatments. In March 2020, we entered into agreements with several outside research laboratories that will conduct research on WP1122 for antiviral properties against a co-development agreement with Houston Pharmaceuticals, Inc., or HPI, which culminated with the mergerrange of Moleculin, LLC into MBI coincident withviruses, including Coronavirus. We have also added experts to our initial public offering allowing usScience Advisory Board to gain control of the WP1066 Portfolio.

Moleculin, LLC was formed in 2006 and was working to develop the WP1066 Portfolio it licensed from MD Anderson. On May 2, 2016, Moleculin, LLC was merged with and into MBI. As a result of the merger, we issued the holders of Moleculin, LLC equity interests and convertible notes representing in the aggregate 999,931 shares ofsupport our common stock. Since Moleculin, LLC commenced operations in 2006, substantially all of its efforts had been focused on research, development and the advancement of the WP1066 Portfolio. Moleculin, LLC did not generate any revenue from product sales and, as a result, incurred significant losses.

In June 2018, we formed Moleculin Australia Pty. Ltd., a wholly-owned subsidiary to oversee pre-clinical development in Australia. The Australian government provides an aggressive incentive for research and development carried out in their country. We believe having an Australian subsidiary could provide a great opportunity to speed up pre-clinical development and reduce the overall cost of our continued drug developmentanti-viral efforts.

We do not have manufacturing facilities and all manufacturing activitiesThe FDA has created a special emergency program for possible therapies, the Coronavirus Treatment Acceleration Program (CTAP). FDA comments that it uses every available method to move new treatments to patients as quickly as possible, while at the same time finding out whether they are contracted out to third parties. Additionally, we do not have a sales organization.

Technology Overview

We have been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all of our drug technologies, as these patent rights are ownedhelpful or harmful. As cited by MD Anderson. The Annamycin drug substance is no longer covered by any existing patent protection, but on July 10, 2019, we submitted patent applications for formulation, synthetic process and reconstitution related to our Annamycin drug product candidate. If these patent applications are approved, of which we can provide no assurance, this would provide potentially 20 years of protection for our drug. Independently from potential patent protection, in 2018 we have received Orphan Drug designation (“ODD”) from the FDA for Annamycin for the treatment of AMLon their CTAP website:
“Immediately upon receipt, triaged requests from developers and in 2019 we received ODD for WP1066 for the treatment of glioblastoma. This may enable market exclusivity of 7 years from the date of approval ofscientists seeking to develop or evaluate new drug and biologic therapies …..FDA will generally respond within a New Drug Application (“NDA”) in the United States. During that period FDA generally could not approve another product with the same active moiety for the same use. We also intend to apply for similar status inday.

Next Generation Anthracycline

Chemotherapy continues to be a cornerstone of cancer therapy. DespiteComparing the progress made with immunotherapy and precision medicine, the first-line treatment for many cancers continues to include chemotherapy. And, in part becauseintended turnaround times of the emphasis placed on alternativesFDA above to chemotherapy, we believe that not enough has been done to improve chemotherapeutic agents to make them safer and more effective. Anthracyclines are a class of chemotherapy drugs designed to destroy the DNA of targeted cancer cells. Acute leukemia is one of a number of cancers that are usually treated with anthracyclines. In the case of acute leukemia, anthracyclines are typically used in “induction therapy,” where the goal is to induce sufficient remission of patients’ blood-born tumor cells to allowits normal 60 day turnaround time for a curative bone marrow transplant.

Two key factors limit the safetypre-IND meeting request and effectiveness of anthracyclines: cardiotoxicity (potential to damage the heart) and multidrug resistance.30 days for an IND review, these are expedited timelines. We believe Annamycin may overcomeplan on utilizing these two factors; if preliminary data are borne out, Annamycin may ultimately provide clinically meaningful benefits over currently approved anthracyclines in treating certain cancers. Preliminary data from very early-stage clinical trials suggest acute leukemia as a potentially opportune indication in which to further study Annamycin.

One of the key dose-limiting toxicities associated with currently available anthracyclines (including the anthracycline in the recently approved drug, Vyxeos) is the propensity to induce life-threatening heart damage (also known as cardiotoxity). This is a particularly significant risk for pediatric leukemia patients, whose life spans can be severely shortened by the induction therapy intended to cure them of acute leukemia. In the animal model recommended by the FDA as an indicator of human cardiotoxicity, the non-liposomal (free) form of Annamycin has been shown to be significantly less likely than doxorubicin to create heart lesions in mice, and the liposomal formulation ("L-Annamycin") has been shown in these same models to have reduced cardiotoxicity to the point where it is unlikely to cause harm to human patients. If this characteristic is shown to be the same in humans, it may allow L-Annamycin to be used more aggressively to help patients achieve remission. This would be especially valuable in the case of pediatric acute leukemia (both AML and ALL) because of the potential impact of cardiotoxicity on long-term survival. In our current Phase I/II trial for Annamycin, we are collecting data to further validate the design intent of Annamycin to have little or no cardiotoxicity. Unless otherwise noted, all of our references to Annamycin refer to the liposomal form or L-Annamycin.

In addition, the effectiveness of currently approved anthracyclines is limited by their propensity for succumbing to “multidrug resistance.” This can occur where, as a natural defense mechanism, transmembrane proteins acting as transporters (one type of which is referred to as a “P-glycoprotein pump” or “ABCB1 transporter”) develop on the outer surface of cells to expel perceived threats like anthracyclines. In many instances, the likelihood of cardiotoxicity (and other serious side effects) prevents increasing the dosing of current therapies in order to overcome multidrug resistance. As a result, most patients cannot receive current anthracyclines in doses that are adequate to produce lasting remission and thereby qualify for a bone marrow transplant. A laboratory study has suggested that Annamycin may resist being expelled by P-glycoprotein pumps and similar multidrug resistance transporters,aspects, which may meanshorten the drug circumvents multidrug resistance. This characteristic has been shownvarious FDA review periods in pre-clinical testing to allow for higher drug uptake in diseased cells, which we believe could allow for more effective induction therapyconnection with less risk to the patient.

STAT3 Immune/Transcription Modulators: Enabling Immune Response and Inhibiting p-STAT3 and other Oncogenic Transcription Factors –

We believe our WP1066 Portfolio (including lead drugs WP1066, WP1220 and WP1732) represents a novel class of agents capable of hitting multiple targets, including the activated form of a key oncogenic transcription factor, STAT3. A substantial body of published research has identified STAT3 as a master regulator of a wide range of tumors and has linked the activated form, p-STAT3, with the survival and progression of these tumors. For this reason, it is widely believed that targeted inhibition of p-STAT3 may be an effective way to reduce or eliminate the progression of these diseases.

The high level of anticancer activity demonstrated in multiple tumors in animal models by WP1066 and WP1732 is potentially related to their ability to also inhibit such important key oncogenic transcription factors like c-Myc and HIF-1α. In addition to direct anticancer effects not related to the function of the immune system, our lead drug WP1066 has also been shown to boost immune response in animals, in part by inhibiting activity of Regulatory T cells ("Tregs"), which are coopted by tumors to evade the immune system. We believe the dual effect of (1) directly inhibiting tumor growth and inducing tumor cell
23


death and (2) separately boosting and directing the natural immune response to tumors is therapeutically highly promising. If additional preclinical and clinical data validate the two avenues of apparent activity, this class of drugs may be well-suited to treat a wide range of tumors, both as single agents and as critical elements of successful combination therapies targeting even some of the most difficult-to-treat cancers.

The recent oncology drug landscape has been dominated by immunotherapy, specifically including checkpoint inhibitors. In just the last 5 years, checkpoint inhibitors (such as Opdivo and Keytruda) have reached over $10 billion in annual revenues. To summarize checkpoint blockade therapy, the T-Cells within an individual’s own immune systems should be capable of identifying tumor cells and destroying them before they destroy the individual. Unfortunately, tumors develop the ability to prevent this natural immune response by regulating the expression of certain receptors referred to as “immune checkpoints” that then bind to T-Cells and prevent them from attacking the tumor. Immune checkpoint inhibitors are antibodies that block these receptor mechanisms and allow the T-Cells to act normally and attack the tumor.

In certain types of tumors, like melanoma, checkpoint inhibitors work well, and the results can be impressive, creating durable suppression of tumors where no other therapy had succeeded. However, despite the outstanding results in select patients, checkpoint inhibitors benefit only a limited number of patients in certain cancers, and they are essentially not effective in what are called “non-responsive” tumors like glioblastoma and pancreatic cancer, among others. As a result, companies are now focusing heavily on combination therapies, combining immune checkpoint inhibitors with chemotherapy, as well as other agents. There appears to be tremendous demand and we believe there is a clear need for new chemotherapeutic agents that, by their specific mechanism of action, would produce potent combination effects with immune checkpoint inhibitors, and that additionally can boost immune system response on their own. In this regard, there is early nonclinical evidence that WP1066, as a single agent, has the ability to reverse immune tolerance in brain tumor patients (Cancer Res, 67(20), 9630, 2007), and preliminary data in animal models that suggests WP1066 may have a potential for combination use with checkpoint inhibitors.

Recently published research papers have presented several findings that may point to major new opportunities for Moleculin’s WP1066 class of drugs. One such article suggested that our STAT3 inhibitor WP1066 abrogated PD-L1/2 expression in cancer cells and may be a useful agent in addition to checkpoint inhibitor immunotherapy in cancer patients (J Clin Exp Hematop, 57(1), 21-25, 2017). Other published results show that CTLA4-induced immune suppression occurs primarily via an intrinsic STAT3 pathway, suggesting that, through its inhibition of activated STAT3, WP1066 might work well in combination with this checkpoint inhibitor (Cancer Res, 77(18), 5118–28, 2017).

A separate paper presents selected key transcription factors as being responsible for the upregulation of an often-targeted checkpoint actor in tumors known as PD-L1. Some of the most important transcription factors identified were HIF-1α, c-Myc and STAT3, the very targets for which WP1066 was designed (Front Pharmacol, 2018 May 22, 9:536, doi: 10.3389/ fphar.2018.00536, eCollection 2018). In summary, although much of the data is nonclinical and all of it is preliminary, we are optimistic that administration of WP1066 could lead to improved treatment results in many patients receiving checkpoint inhibitor therapy.

Metabolism/Glycosylation Inhibitors: Using the Warburg Effect to Starve Tumor Cells to Death –

Science has recognized that many types of cancer cells have a unique metabolism, distinct from that of normal cells. Cancer cells’ dependence on glycolysis (a specific way of converting glucose into energy) to proliferate and metastasize has been described as the “sweet tooth of cancer” and is a classic example of how the metabolism of cancer cells and normal cells differ. Glycolysis is a glucose-intensive means of producing energy that is used by normal cells only if oxygen levels are low.

However, many types of tumor cells are essentially addicted to glycolysis even in the presence of abundant oxygen. This is known as the “Warburg Effect” after its discoverer, Dr. Otto Warburg, and such tumors are said to be highly “glycolytic.”

This phenomenon of tumors relying preferentially on glycolysis and the resulting dramatic increase of glucose uptake to fulfill their metabolic demands has already been utilized very effectively in cancer diagnostics. It is the Warburg Effect that enables imaging of actively growing tumors by positron emission tomography (“PET scans”). This diagnostic test uses a fluorine-18 radiolabeled glucose decoy called F18DG that accumulates disproportionately in tumors, using the same process that increases glucose uptake and retention in cancer cells.

The success of PET scanning points to the potential therapeutic benefit of the tumor-specific inhibition of glycolysis that would block energy (adenosine triphosphate (“ATP”)) production and could potentially “starve tumor cells to death” and/or make them sensitive to other existing therapies, including radiotherapy. Unsuccessful attempts to realize this therapeutic
24


potential have been made in the past, using a glucose decoy known as “2-deoxy-D-glucose” ("2-DG"). Those attempts to target the metabolism of tumor cells have failed, we believe, because of 2-DG’s lack of drug-like properties that include rapid metabolism, short half-life and limited tissue-organ distribution. Essentially, not enough 2-DG could be delivered to its intended target.

We have designed and are studying a novel and patented prodrug of 2-DG (WP1122). We believe WP1122 has the potential for developing into a technology platform for enabling increased cellular uptake, increased drug half-life and, importantly, enabling greater uptake and retention in organs where the most resistant and glycolytic tumors are localized, including the brain and pancreas.

Altering Glycosylation to Enhance Immune Checkpoint Therapy –

A recently published study (Am J Cancer Res, 8(9), 1837-1846, 2018) focused on the analysis of tumor resistance to immune checkpoint therapy. The study found that a process known as glycosylation plays an important role in the ability of checkpoint receptors to suppress immune activity and thereby protect tumors from attack. The researchers discovered that an alteration of the glycosylation of these receptor mechanisms could effectively prevent this evasion of the immune system. This study found that 2-deoxyglucose, or 2-DG, was capable of making this alteration. Although the data are preliminary, the findings suggest that 2-DG could act as an effective anticancer agent in combination with checkpoint inhibitors and potentially with other anticancer therapies.

Attempting to use 2-DG as a drug, however, faces the same problems discussed above. 2-DG’s short circulation time and lack of other drug-like properties mean the drug does not stay in the system long enough or concentrate sufficiently in targeted organs, which severely limits its effectiveness. This suggests a possible role for our patented drug candidate, WP1122. WP1122 is a prodrug of 2-DG, meaning it is a molecule that may be able to be converted into pharmacologically active 2-DG within the body of the patient. The design of WP1122 is intended to allow for a longer circulation time and improved organ distribution, which should provide it a greater opportunity to become an effective drug.

We intend to study WP1122 for both its ability to directly inhibit tumor activity and to potentiate existing therapies via an inhibition of tumor metabolism and to improve the performance of checkpoint inhibitors by reducing the effect of glycosylation and have begun the necessary preclinical work required to file an IND.

Clinical Activity

Annamycin had previously been in clinical trials with a prior drug developer pursuant to an application for Investigational New Drug status (“IND”) that had been filed with the FDA. Due to a lack of development activity by the prior drug developer, this IND was terminated. To permit the renewed investigation of Annamycin, we submitted a new IND for a Phase I/II trial for the treatment of relapsed or refractory AML in August 2017, which was subsequently allowed by the FDA in September 2017. Patient treatment began in the US in March 2018. In March 2019,WP1122, although we announced that the first cohort in the US was completed and announced top-line results. We are now in the second cohort in our Phase I portion of the US trial.

With regard to additional Annamycin clinical activity, we received Polish National Office approval in June 2018 for a Clinical Trial authorization (“CTA”) in Poland, which enabled us to begin a Phase I/II clinical trial there to study Annamycin for the treatment of relapsed or refractory AML. During the first half of 2019, we began screening and treating patients in Poland. We have now completed the first two cohorts and are now treating patients in the third cohort.

We continue to recruit and contract with clinics both in the United States and Poland. We can provide no assurance of additional recruitment or that treatments will occur in the near term and on a timely basis, if at all.

A physician-sponsored IND for a Phase I trial of WP1066 in patients with recurrent malignant glioma and brain metastasis from melanoma was allowed by the FDA in December 2017. In July 2018, this trial opened for recruitment in the US. This trial is now inwill shorten its third cohort of the Phase I portion of the planned protocol. Because this trial is physician led, we are limited in our ability to manage the trial.

With regard to additional clinical activity on other drugs, we initiated a proof-of-concept clinical trial in Poland to study our drug candidate WP1220, a part of the WP1066 portfolio, for the topical treatment of cutaneous T-cell lymphoma (“CTCL”). In 2018, we filed a CTA in Poland for this trial, which was approved in January 2019, giving us a third drug in clinic and our fourth clinical trial. We began treating patients during the first quarter of 2019.

25


We have begun planning and performing the necessary pre-clinical work required to submit anreview period or eventually approve any IND for WP1732 and WP1122. In June 2018, we entered into an agreement with The University of Iowa Pharmaceuticals for the development of a formulation for WP1732. This agreement marked the beginning of creating a preclinical package to submit to the FDA in order to request Investigational New Drug status. We have now completed initial formulation development, and our IND-enabling toxicology work will be progressing via our Australian subsidiary, Moleculin Australia. As a result of our toxicology work, we are investigating improvements to the formulation of WP1732. We now expect to submit an IND in the US in 2020.

We also continue to sponsor ongoing research at MD Anderson in order to improve and expand our drug development pipeline.application.

Recent Business Developments

Below are recent business developments.

Completion of Lymphoma Trial EnrollmentAnnamycin

On August 13, 2019 we announced our proof of concept clinical trialApproved to evaluate our p-STAT3 inhibitor, WP1220, for the topical treatment of CTCL has reached full enrollment. This proof of concept, if successful, could be an important first demonstration of a therapeutic effect in humans from such a p-STAT3 inhibitor.We believe showing activity with one of our STAT3 inhibitors could be an indicator of both the value of p-STAT3 as a target and the potential for our drugs in other cancers where STAT3 is highly activated.Accelerate European Clinical Trial

WP1066 Potentially CapableWe announced on April 28, 2020, that we are now authorized by the Polish Department of Immune ReprogrammingRegistration of Medicinal Products known as URPL to accelerate the Phase 1 dose escalation portion of our clinical trial of Annamycin for the treatment of AML. The URPL has allowed an amendment to the Annamycin clinical trial protocol, which among other things, includes an increase in Glioblastoma Animal Modelsthe dose escalation increment between cohorts from 30 mg/m2 to 60 mg/m2. The clinical trial is currently recruiting for the 240 mg/m2 cohort, so this amendment allows the next cohort to increase to 300 mg/m2, assuming all requirements for safety are met with the 240 mg/m2 cohort.

Positive Safety Data in EU AML Trial

On August 6, 2019,April 2, 2020, we announced that a paper entitled "Immunological Reprogrammingwe completed the latest (210 mg/m2) cohort in the CNS Tumor Microenvironment and Therapeutic Efficacy of Radiotherapy with STAT3 Blockade" will be presented at the Inaugural Conference on Brain Metastases, in New York City, August 16-17, 2019. Dr. Martina Ott, of MD Anderson Cancer Center, will be presenting the findings of research she conducted in collaboration with Dr. Amy Heimberger (the Principle Investigator of the current investigator-initiated clinical trial of WP1066 for brain tumors) in combining WP1066 with radiation therapy in glioblastoma animal models. One of the findings of her research that is especially encouraging is that immune-competent mice treated with both radiation and WP1066 developed an immunological memory that enabled them to prevent regrowth of the tumor after these tumor cells were reintroduced. The result was the development of long-term survivors, leading to an increase in overall survival in these models. Of note was that mice with a compromised immune system did not show this effect. We believe that these findings will have a profound impact on understanding the role of STAT3 inhibition, as well as help focus our continued development of WP1066 in this disease. This study was also particularly interesting because it showed the most robust immunological responses were located in the CNS (Central Nervous System) tumor microenvironment rather than peripheral non-tumor tissue. Importantly, the study indicated that the combination of STAT3 inhibition with whole brain radiotherapy had the capacity to enhance the therapeutic effect against established tumors based on immunological competence. We plan to explore this potential in human clinical trials.

At Market Issuance Sales Agreement

We entered into an At Market Issuance Sales Agreement with Oppenheimer & Co. Inc. on July 23, 2019 (the "Opco Agreement"). Pursuant to the terms of the Opco Agreement, we may sell from time to time through the Agent shares of our common stock, par value $0.001 per share, with an aggregate sales price of up to $15 million.

Annamycin in Acute Myeloid Leukemia in Poland Advances to 3rd Cohort

On July 18, 2019, we announced additional positive interim safety and efficacy data from our ongoingEuropean open label, single arm Phase 1/2 studyclinical trial of Annamycin in Poland. Three patients were treated at a dose level of 150 mg/m2 with no drug-related adverse events, including no signs of cardiotoxicity. The results for all 3 patients were reviewed by the Drug Safety Review Committee, which determined that the trial could progress to the next higher dose level of 180 mg/m2. To date in Poland, one patient experienced grade 2 mucositis (which resolved to grade 1 within 2 days) and no other adverse events related to Annamycin have been reported. One patient has completed treatment in the 120 mg/m2 (second) cohort in our parallel US clinical trial (the US trial started at a lower initial dose of 100 mg/m2).

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

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

Patent Filing to Cover New Coronavirus Drug Candidate

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

SEC matters

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

Research and Development Expense. Research and development ("R&D")(R&D) expense was $2.1$3.2 million and $4.2$2.9 million for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively. The decreaseincrease of $2.1$0.3 million is mainly related to increased clinical trial activity, increased license fees and sponsored research agreements, costs incurred in 2018related to manufacturing of producing additional drug product for our Annamycin clinical trials.and two additional employees in research and development headcount.

General and Administrative Expense. General and administrative expense was $1.5$1.8 million and $1.2$1.6 million for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively. The increase of $0.3$0.2 million was mainly attributable to increase in G&A relatedincreased payroll costs.costs for an additional finance employee, increased stock-based compensation expense for annual employee stock options, and increased costs for directors and officer's liability insurance.

Gain from Change in Fair Value of Warrant Liability. We recorded a net gain of $2.4$3.8 million in the secondfirst quarter of 20192020 as compared to a net gain of $0.3$0.5 million in the secondfirst quarter of 2018,2019, for the change in fair value on revaluation of our warrant liability associated with our warrants issued in conjunction with our stock offerings in April 2019, March 2019, June 2018, February 2018, and February 2017.offerings. We are required to revalue certain of theour liability-classified warrants at the time of each warrant exercise, and at the end of each reporting period and reflect in the statement of operations a gain or loss from the change in fair value of the warrant in the period in which the change occurred. We calculated the fair value of the warrants outstanding using the Black-Scholes model. A gain results principally from a decline in our share price during the period and a loss results principally from an increase in our share price. During the quarter, our stock price fluctuated greatly.

Cash used in operating activities

Cash used in operations was $9.2$4.3 million for the sixthree months ended June 30, 2019.March 31, 2020. This $2.9$0.5 million increase over the prior year period of $6.3$3.8 million was mainlyprimarily due to: 1) payments for developing, manufacturing and testing drug product as we prepared for clinical trials; 2) an increase in R&D employee and contractor headcount and associated payroll costs; 3) an increase in paid sponsored research and related expenses; and 4) an increase in license fees. These are all a reflection of the ongoing clinical and pre-clinical activity and the associated increase in G&Ageneral and administrative support for our three core drug technologies.

Cash used in investing activities

Net cash used in investing activities was $0.03 million$2,000 for the sixthree months ended June 30, 2019March 31, 2020 compared to $0.01 million$15,000 for the sixthree months ended June 30, 2018. We purchased additionalMarch 31, 2019. The decrease relates to purchases in 2019 related to furniture and fixtures for our corporate apartment, as well as additional electronic equipment for employees and our corporate office.

Cash provided in financing activities

In April 2019,February 2020, we completedentered into subscription agreements with institutional investors to purchase an aggregate of 9,375,000 units7,500,000 shares of our common stock and warrants to purchase 5,625,000 shares of common stock at a combined public offering price of $1.60$0.80 per unit in a registered direct offering. Each unit is comprised of one share of common stock and 0.5 of arelated warrant to purchase one share of common stock resulting in gross proceeds of $15.0$6.0 million. Each warrant has an exercise price of $1.75$1.05 per share and iswill be exercisable immediately. The warrantssix months from the date of issuance and will expire five years from the date of issuance.they are first exercisable.

Additionally, duringDuring the second quarter of 2019, 1,413,018 shares were issued due to the exercise of various warrants related to past public offerings. Gross proceeds received due to these exercises approximated $1.6 million.

Inthree months ended March 2019, we completed an underwritten offering of 5,250,000 units, each unit consistingshares of (i) one shareour common stock and warrants to purchase 2,650,000 shares of common stock and (ii) 0.5 of a warrant to purchase one share of common stock. The public offering price of the units was $1.00 per unit, and the underwriter agreed to purchase the units from us at a price of $0.93 per Unit. The warrants included in the units are immediately exercisable at a price of $1.10 per share, subject to adjustments in certain circumstances, and will expire
30


five years from the date of issuance. Thefor net proceeds from the transaction wasof $4.7 million after deducting the underwriting discount and estimated offering expenses.

In June 2018,expenses and we entered into an agreement with institutional investors for a registered direct offering of securities for the sale by us of 1,092,636sold 605,367 shares of our common stock at a purchase price of $2.105 per share. Concurrently with the sale of the common shares, we also sold warrants to purchase 710,212 shares of common stock. We sold the common shares and warrantsLincoln Park Capital Fund, LLC for net proceeds of $2.1 million after deducting certain fees due to the placement agent and transaction expenses. Subject to certain beneficial ownership limitations, the warrants will be initially exercisable on the six-month anniversary of the issuance date at an exercise price equal to $2.02 per share of common stock, subject to adjustments as provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date.

In February 2018, we entered into a securities purchase agreement with certain institutional investors for the sale by us of 4,290,000 shares of our common stock, at a purchase price of $2.10 per share. Concurrently with the sale of the common shares, we also sold warrants to purchase 2,145,000 shares of common stock. We sold the common shares and warrants for net proceeds of $8.2 million after deducting certain fees due to the placement agent and transaction expenses. Subject to certain beneficial ownership limitations, the warrants became exercisable on the six-month anniversary of the issuance date at an exercise price equal to $2.80 per share of common stock, subject to adjustments as provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date.$0.9 million.

We believe that our existing cash and cash equivalents as of June 30, 2019,March 31, 2020 combined with the shares we sold in April 2020 through the At Market Issuance Sales Agreement will be sufficient to fund our planned operations into the secondfirst quarter of 2020,2021, without the issuance of additional equity for cash. SuchAny such issuances should extend the funding of our planned operations significantly beyond the secondfirst quarter of 2020.2021. Such plans are subject to our stock price, market conditions, changes in planned expenses depending on clinical enrollment progress, the use of drug product or a combination thereof. Based on the Company's current assessment, the Company does not expect any material impact on its long-term development timeline and its liquidity due to the worldwide spread of the COVID-19 virus.

We will not generate revenue from product sales unless and until we successfully complete development of, obtain regulatory approval for and begin to commercialize one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital to fund our future operations. Until such time that we can generate substantial revenue from product sales, if ever, we expect to finance our operating activities through a combination of equity offerings and debt financings, and we may seek to raise additional capital through strategic collaborations. However, we may be unable to raise additional funds or enter into such arrangements when needed on favorable terms, or at all, which would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our development programs or commercialization efforts or grant to others rights to develop or market product candidates that we would otherwise prefer to develop and market ourselves. Failure to receive additional funding could cause us to cease operations, in part or in full. Furthermore, even if we believe we have sufficient funds for our
23


current or future operating plans, we may seek additional capital due to favorable market conditions or strategic considerations, which may cause dilution to our existing stockholders.


Critical Accounting Policies and Significant Judgments and Estimates
 
The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
 
We believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.
 
Acquisition and Creation of a Subsidiary
We acquired Moleculin, LLC on May 2, 2016, and, since such date our consolidated financial statements have included the operations of Moleculin, LLC. We account for acquired businesses using the acquisition method of accounting, which requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair
31


values as of the acquisition date and that the fair value of acquired in-process research and development (“IPR&D”) be recorded on the balance sheet. Transaction costs are expensed as incurred. Any excess of the consideration transferred over the assigned values of the net assets acquired will be recorded as goodwill. We obtained input from third-parties regarding our tangible and intangible assets and other information necessary to measure the fair value of the assets acquired and liabilities assumed in connection with the acquisition of Moleculin, LLC. In June 2018, MBI formed Moleculin Australia Pty. Ltd., ("MAPL"), a wholly-owned subsidiary, to begin preclinical development in Australia for WP1732. This may enable us to enjoy the benefits of certain research and development tax credits in Australia. In February 2019, the Company entered into an agreement with Animal Life Sciences, LLC ("ALI"), where the Company has granted a sublicense to ALI to research, develop, make, have made, use, offer to sell, sell, export or import and commercialize certain licensed products and share development data. ALI issued to the Company a 10% membership interest in ALI. In June 2019 ALI became Animal Life Sciences, Inc., incorporated in Nevada.

Research and Development Costs
  
We record accrued expenses for estimated costs of our research and development activities conducted by third-party service providers, which include the conductingconduct of pre-clinical and clinical studies and the preparation for clinical trials and contract manufacturing activities. We record the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced, and we include these costs in accrued liabilities in the balance sheets and within research and development expense in the statements of operations. These costs are a significant component of our research and development expenses. We record accrued expenses for these costs based on the estimated amount of work completed and in accordance with agreements established with these third parties.
 
We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As actual costs become known, we adjust our accrued estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed may vary from our estimates and could result in us reporting amounts that are too high or too low in any particular period. Our accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from clinical research organizations and other third-party service providers. To date, there have been no material differences from our accrued expenses to actual expenses.
 
Impairment of Long-Lived Assets
 
Management reviews long-livedevaluates the recoverability of its property and equipment and amortizable intangible assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be realizablerecoverable or at a minimum annually during the fourth quarter of the year. If an evaluationRecoverability of these assets is required,measured by a comparison of the estimatedcarrying amounts to the future undiscounted cash flows associated with the assetassets are comparedexpected to generate. If such review indicates that the asset’s carrying value to determine if an impairmentamount of property and equipment and amortizable intangible assets is not recoverable, the carrying amount of such asset is necessary.reduced to fair value.

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

Accounting for warrants

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


warrant exercise in cash and classified as equity when the Company settles a warrant exercise in shares of its common stock. Based on this guidance, we determined that certain of our warrants to purchase shares of common stock related to equity transactions meet the criteria for classification as a liability. Accordingly, the warrants were classified as a warrant liability and are subject to fair value remeasurement at exercise and balance sheet date with the changes in fair value recognized in earnings.

Our financial instruments consist primarily of non-trade receivables, account payables, accrued expenses, and a warrant liability. The effectcarrying amount of any impairmentnon-trade receivables, accounts payables, and accrued expenses approximates their fair value because of the short-term maturity of such.

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

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

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

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

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

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

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

ITEM 4. CONTROLS AND PROCEDURES
 
Evaluation of Disclosure Controls and Procedures.
 
We maintain disclosure controls and procedures designed to ensure that material information required to be disclosed in our filings under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information is accumulated and communicated to our
25


management, including our Chief Executive Officer (“CEO”)(CEO) and Chief Financial Officer (“CFO”)(CFO), as appropriate, to allow timely decisions regarding required disclosures. Our CEO and CFO have evaluated these disclosure controls and procedures as of the end of the period covered by this quarterly report on Form 10-Q and have determined that such disclosure controls and procedures were not effective as disclosed below.
 
In light of the material weakness described below, we performed additional procedures during the quarter and additional analysis and procedures post-closing to ensure our unaudited condensed consolidated condensed financial statements were prepared in accordance with generally accepted accounting principles. Accordingly, we believe that the condensed consolidated financial statements included in this report fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented.
 
A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board Auditing Standard 1305) or combination of control deficiencies that result in more than a remote likelihood that a material misstatement of the annual or interim condensed consolidated financial statements will not be prevented or detected.

During the last quarter of fiscal 2016, and as our operational activities increased, management determined that it does not have sufficient segregation of duties within its accounting functions, which is a basic internal control. Due to our size and nature, segregation of all conflicting duties may not always be possible and may not be economically feasible. However, to the extent possible, the initiation of transactions, the custody of assets and the recording of transactions should be performed by separate individuals. Management evaluated the impact of our failure to maintain effective segregation of duties on our assessment of our internal control over financial reporting and has concluded that the control deficiency represents a material weakness. In 2018, management added two accounting positions,A number of the issues related to segregation of duties were remediated with new information technology systems and policies and procedures during 2019. Management added additional fraudaccounting and IT personnel in 2019 and implemented a new accounting software system, accounting policies, and banking controls. Management intends to further enhance its accounting staff and enhance the controls with regardssurrounding its system of financial accounting and reporting, as soon as economically feasible and sustainable, to our banking systems, and replaced the accounting system with a more robust accounting system that should assist in mitigatingfurther remediate this material weakness. Along with these improvements, changes were made in our authorization processes to improve segregation of duties. Certain improvements in segregation of duties are currently being acted uponDuring 2020, we implemented the ERP system for electronic payments and addressed, mainly as to the controls on information technologyfurther updated roles, policies and procedures within those systems. Management may further increase its accounting staff to remediate this material weakness.

We continuously seek to improve the efficiency and effectiveness of our internal controls. There has been no changechanges, except for items described above, in our internal control over financial reporting during our most recent calendar quarterthat occurred in the three months ended March 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. DuringSpecifically, our employees are working remotely due to the second quarter of 2019,COVID-19 pandemic but, we began scoping and planning the implementation of requireddo not believe that our adjustments to how we work have materially impacted our internal controls utilizing outside consultants.over financial reporting. We continue to monitor and access the potential impact of the COVID-19 pandemic, and the related shelter-in-place requirements, on our internal controls and strive to minimize the impact on our internal control design and operating effectiveness.

ITEM 1A. RISK FACTORS
 
For information regarding factors that could affect our results of operations, financial condition and liquidity, refer to the section entitled “Risk Factors” in Part I, Item 1A in our annual report on Form 10-K for the year ended December 31, 2018.2019. Except as updated below, there have been no material changes from the risk factors previously disclosed in our annual report on Form 10-K for the year ended December 31, 20182019 as filed with the SEC.

The SEC issued an order suspending the trading of our common stock.

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

With respect to the COVID-19 outbreak specifically, such outbreak could also potentially affect the business of the FDA, EMA or other health authorities, which could result in delays in meetings related to planned clinical trials and ultimately of reviews and approvals of our product candidates.

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


ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On April 23, 2019 we entered into definitive agreements with institutional investors to purchase an aggregate of 9,375,000 units at a public offering price of $1.60 per unit in a registered direct offering. Each unit is comprised of one share of common stock and 0.5 of a warrant to purchase one share of common stock resulting in gross proceeds of $15.0 million. Pursuant to the Placement Agent Agreement we entered into in connection with the offering, we issued to Oppenheimer & Co. Inc. a five-year warrant to purchase up to 6% of the aggregate number of shares of common stock sold in the offering (the "Oppenheimer Warrant"). The exercise price of the Oppenheimer Warrant is $1.75 per share. The Oppenheimer Warrant has been deemed underwriting compensation by FINRA and therefore shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales of the offering, pursuant to Rule 5110(g)(1) of FINRA's Rules. The Oppenheimer Warrant was issued pursuant to Section 4(a)(2) of the Securities Act. None.
