Business, basis of presentation, new accounting standards and summary of significant accounting policies | 1. Business, basis of presentation, new accounting standards and summary of significant accounting policies General NeuroBo Pharmaceuticals, Inc. (the “Company), a Delaware corporation, and its subsidiaries are referred to collectively in these notes to the financial statements of the Company as “NeuroBo,” “we,” “our” and “us.” We are a clinical-stage biotechnology company focused primarily on cardiometabolic diseases. NeuroBo has two programs focused primarily on treatment of metabolic dysfunction-associated steatohepatitis (“MASH”) and obesity. MASH was formerly known as non-alcoholic steatohepatitis (“NASH”). The American Association for the Study of Liver Diseases (“AASLD”) and its European and Latin American counterparts changed the name to metabolic dysfunction-associated steatohepatitis to reflect the complexity of the disease. ● DA-1241 is a novel G-Protein-Coupled Receptor 119 (“GPR119”) agonist with development optionality as a standalone and/or combination therapy for both MASH and type 2 diabetes. Agonism of GPR119 in the gut promotes the release of key gut peptides GLP-1, GIP, and PYY. These peptides play a further role in glucose metabolism, lipid metabolism and weight loss. DA-1241 has beneficial effects on glucose, lipid profile and liver inflammation, supported by potential efficacy demonstrated during in vivo preclinical studies. ● DA-1726 is a novel oxyntomodulin analogue functioning as a GLP-1 receptor (“GLP1R”) and glucagon receptor (“GCGR”) dual agonist for the treatment of obesity that is to be administered once weekly subcutaneously. DA-1726 acts as a dual agonist of GLP1R and GCGR. While we primarily focus our financial resources and management’s attention on the development of DA-1241 and DA-1726, we also have four legacy therapeutic programs designed to impact a range of indications in viral, neurodegenerative and cardiometabolic diseases which we continue to consider for out-licensing and divestiture opportunities . Our operations have consisted principally of performing research and development (“R&D”) activities, preclinical developments, clinical trials, and raising capital. Our activities are subject to significant risks and uncertainties, including failing to secure additional funding before sustainable revenues and profit from operations are achieved. Common stock reverse stock splits In December 2023, we completed a one-for-eight reverse stock split of our common stock (the “2023 Reverse Stock Split”). As a result, every eight shares of our issued and outstanding common stock were combined, converted and changed into one share of our common stock. Any fraction of a share of our common stock that was created as a result of the reverse stock split was rounded down to the next whole share and the stockholder received cash equal to the market value of the fractional share, determined by multiplying such fraction by the closing sales price of our common stock as reported on on the last trading day before the reverse stock split. The 2023 Reverse Stock Split was initially approved by our stockholders at the annual meeting of stockholders in J one-for-five one-for-eight In September 2022, we completed a 1-for-30 (the “2022 Reverse Stock Split”). As a result, every thirty shares of our issued and outstanding common stock were combined, converted and changed into one share of our common stock. Any fraction of a share of our common stock that was created as a result of the reverse stock split was rounded down to the next whole share and the stockholder received cash equal to the market value of the fractional share, determined by multiplying such fraction by the closing sales price of our common stock as reported on Nasdaq on the last trading day before the reverse stock split. The 2022 Reverse Stock Split was initially approved by our stockholders at the annual meeting of stockholders in J one-for-five one-for-thirty-five Neither the 2023 Reverse Stock Split nor the 2022 Reverse Stock Split impacted the number of authorized shares of common stock of 100,000,000 shares. For each of the reverse stock splits, a proportionate adjustment was made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options, and warrants to purchase shares of our common stock, the number of shares issuable upon vesting of restricted stock units (“RSUs”) and the number of shares reserved for issuance pursuant to our equity incentive compensation plans. Specifically, for the Series A and B warrants issued in November 2022 that were outstanding on December 20, 2023, the number of outstanding warrants did not change; instead, the warrants have an In the accompanying consolidated financial statements and these notes to consolidated financial statements, all historical numbers of shares of common stock and per share data have been adjusted to give effect to the 2023 Reverse Stock Split and the 2022 Reverse Stock Split. Additionally, since the common stock par value was unchanged, historical amounts for common stock and additional paid-in capital have been adjusted to give effect to the 2023 Reverse Stock Split and the 2022 Reverse Stock Split. Going concern The determination as to whether we can continue as a going concern contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. have been prepared assuming that we will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. This basis of accounting contemplates the recovery of our assets and the satisfaction of our liabilities in the normal course of business. As reflected in the consolidated financial statements, we had $22,435 in cash as of December 31, 2023. We have experienced net losses and negative cash flows from operating activities since our inception and had an accumulated deficit of $108,265 as of December 31, 2023. We have incurred a net loss of $12,470 and used cash of $10,799 for operating activities for the year ended December 31, 2023. Due in large part to the ongoing Phase 2a clinical trial for DA-1241 and Phase 1 clinical trial for DA-1726, we expect to continue to incur net losses and negative cash flows from operating activities for the foreseeable future. These conditions raise substantial doubt about our ability to continue as a going concern. We believe that our existing cash will be sufficient to fund our operations into the fourth quarter of 2024. We plan to continue to fund our operations through a combination of equity offerings, debt financings, or other sources, potentially including collaborations, out-licensing and other similar arrangements. There can be no assurance that we will be able to obtain any sources of financing on acceptable terms, or at all. To the extent that we can raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that impact our ability to conduct our business. If we are unable to raise additional capital, we may slow down or stop our ongoing and planned clinical trials until such time as additional capital is raised and this may have a material adverse effect on us. A. Basis of presentation Our consolidated financial statements include a South Korean subsidiary, NeuroBo Co., Ltd., a wholly owned subsidiary which was dissolved and liquidated in June 2023. The accompanying financial statements were prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Our fiscal year-end is as of and for the year ended December 31st for each year presented. B. New accounting standards Adoption of new accounting standards New accounting standards or accounting standards updates were assessed and determined to be either not applicable or did not have a material impact on our consolidated financial statements or processes. Accounting standards issued but not yet adopted In October 2021, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This ASU requires that an entity (acquirer) recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied Topic 606 to determine what to record for the acquired revenue contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements (if the acquiree prepared financial statements in accordance with generally accepted accounting principles). The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2023, although early adoption is permitted. We do not expect the adoption of this ASU will have a material impact on our consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. This ASU clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2023, although early adoption is permitted. We do not expect the adoption of this ASU will have a material impact on our consolidated financial statements. In December 2023, the FASB issued Other recently issued accounting standards not yet adopted by us are not expected, upon adoption, to have a material impact on our consolidated financial statements. C. Estimates and assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The most significant estimates in our consolidated financial statements relate to accrued expenses and the fair value of stock-based compensation and warrants. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known. D. Cash We maintain cash at financial institutions that at times may exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limits of $250 per bank. Our cash balance includes liquid insured deposits, which are obligations of the program banks in which the deposits are held and qualify for FDIC insurance protection per depositor in each recognized legal category of account ownership in accordance with the rules of the FDIC. To date, we have not experienced any losses related to these funds. E. Property and equipment Property and equipment are recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized over the estimated useful lives of the assets using the straight-line method. The estimated useful life for property and equipment ranges from three F. Leases We assess our contracts at inception to determine whether the contract contains a lease, including evaluation of whether the contract conveys the right to control an explicitly or implicitly identified asset for a period of time. We have recognized right-of-use assets and lease liabilities that represent the net present value of future operating lease payments utilizing a discount rate corresponding to our incremental borrowing rate and amortized over the remaining terms of the leases. For operating leases of a short-term nature, i.e., those with a term of less than twelve months, we recognize lease payments as an expense on a straight-line basis over the remaining lease term. G. Warrant liabilities Warrants are accounted for as liabilities at their fair value if equity accounting treatment is precluded due to provisions existing within the warrant agreements. The change in fair value of the warrant liabilities is recognized as a fair value change in warrant liabilities in the consolidated statements of operations and comprehensive loss and as an operating item in the statement of cash flows. Additionally, issuance costs associated with warrants initially classified as liabilities are expensed as incurred and reflected as financing costs in the accompanying consolidated statements of operations and comprehensive loss. H. Fair value of financial instruments Our financial instruments principally include cash, prepaid expenses, right of use assets, accounts payable, accrued liabilities, lease liabilities and warrant liabilities. The carrying amounts of cash, prepaid expenses and other current assets, accounts payable, and accrued liabilities are reasonable estimates of their fair value because of the short maturity of these items. I. Segment reporting We manage and operate as one business, which is principally the business of development and commercialization of pharmaceutical products. Our business operations are managed by a single executive leadership team, which is led by our chief executive officer. W e do not operate separate lines of business with respect to any of our pharmaceutical products being studied in a clinical environment, and we do not prepare discrete financial information with respect to our pharmaceutical products. Accordingly, we view our business as one reportable operating segment with one geographic location. J. Research and development costs R&D expenditures for clinical development, including upfront licensing fees and milestone payments associated with products that have not yet been approved by the United States Food and Drug Administration, are charged to R&D expense as incurred. These expenses consist of costs incurred in performing development activities, including salaries and benefits, equity-based compensation expense, preclinical expenses, clinical trial and related clinical manufacturing expenses, contract services and other outside expenses. Expenses incurred for certain R&D activities, including expenses associated with particular activities performed by contract research organizations, investigative sites in connection with clinical trials and contract manufacturing organizations, are recognized based on an evaluation of the progress or completion of specific tasks using either time-based measures or data such as information provided to us by our vendors on actual activities completed or costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of expense recognition. Expenses for R&D activities incurred that have yet to be invoiced by the vendors that perform the related activities are reflected in the consolidated financial statements as accrued R&D development expenses. Advance payments for goods or services to be received in the future for R&D activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed. K. Acquired in-process research and development We include costs to acquire or in-license product candidates in acquired in-process R&D (“IPR&D”). When we acquire the right to develop and commercialize a new product candidate, any up-front payments, or any future milestone payments that relate to the acquisition or licensing of such a right are immediately expensed as acquired IPR&D in the period in which they are incurred. These costs are immediately expensed provided that the payments do not also represent processes or activities that would constitute a “business” as defined under GAAP, or provided that the product candidate has not achieved regulatory approval for marketing and absent obtaining such approval, has no alternative future use. Royalties owed on future sales of any licensed product will be expensed in the period the related revenues are recognized. L. General and administrative expenses General and administrative expenses consist primarily of personnel-related costs, including salaries and stock-based compensation costs, for personnel in functions not directly associated with R&D activities. Other significant costs include legal fees related to intellectual property and corporate matters and professional fees for accounting and other services. M. Patent costs Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These costs are included in general and administrative expenses. N. Stock-based compensation Compensation costs related to equity instruments granted are recognized at the grant-date fair value, which is amortized as compensation expense on a straight-line basis over the service period (generally, the vesting period) for both graded and cliff vesting awards. We have elected to account for forfeitures as they occur. O. Income taxes Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and income tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in income tax rates is recorded as a component of the income tax provision in the period that includes the enactment date. Regular assessments are made on the likelihood that our deferred tax assets will be recovered from our future taxable income. Our evaluation is based on estimates, assumptions, and includes an analysis of available positive and negative evidence, giving weight based on the evidence’s relative objectivity. Sources of positive evidence include estimates of future taxable income, future reversal of existing taxable temporary differences, taxable income in carryback years, and available tax planning strategies. Sources of negative evidence include current and cumulative losses in recent years, losses expected in early future years, any history of operating losses or tax credit carryforwards expiring unused, and unsettled circumstances that, if unfavorably resolved, would adversely affect future profit levels. The remaining carrying value of our deferred tax assets, after recording the valuation allowance on our deferred tax assets, is based on our present belief that it is more likely than not that we will be able to generate sufficient future taxable income to utilize such deferred tax assets. The amount of the remaining deferred tax assets considered recoverable could be adjusted if our estimates of future taxable income during the carryforward period change favorably or unfavorably. To the extent we believe that it is more likely than not that some or all the remaining deferred tax assets will not be realized, we must establish a valuation allowance against those deferred tax assets, resulting in additional income tax expense in the period such determination is made. To the extent a valuation allowance currently exists, we will continue to monitor all positive and negative evidence until we believe it is more likely than not that it is no longer necessary, resulting in an income tax benefit in the period such determination is made. Our policy is to recognize both interest and penalties related to uncertain tax positions as part of the income tax provision. A significant judgment is required in evaluating our tax positions, and in determining our provisions for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We establish reserves when, despite our belief that the income tax return positions are fully supportable, certain positions are likely to be challenged and we may ultimately not prevail in defending those positions. P. Foreign currency translation Our foreign subsidiary, dissolved and liquidated in June 2023, used the South Korean Won (KRW) as its functional currency. We translated the assets and liabilities of our foreign operation into United States (“U.S.”) dollars based on the rates of exchange in effect as of the transaction date. The resulting adjustments from the translation process are included in accumulated other comprehensive (loss) income in the accompanying consolidated balance sheets. Certain transactions are settled in foreign currency and are thus translated to U.S. dollars at the rate of exchange in effect at the end of each month. Gains and losses resulting from the translation are included in other income or expense in the accompanying consolidated statements of operations and comprehensive loss. Q. Comprehensive loss Comprehensive loss is comprised of net loss and other comprehensive income or loss. Comprehensive loss includes net loss as well as other changes in stockholders' equity that result from transactions and economic events other than those with stockholders. Comprehensive loss currently consists of net loss and changes in foreign currency translation adjustments. R. Loss per share of common stock Basic earnings or loss per share of common stock is computed by dividing net income or loss available to stockholders of common stock by the weighted average number of shares of common stock. Diluted earnings per share of common stock is computed by dividing net income or loss available to stockholders of common stock by the sum of the weighted average number of shares of common stock and the number of additional shares of common stock that would have been outstanding if our outstanding potentially dilutive securities had been issued. Potentially dilutive securities include convertible preferred stock, outstanding stock options, non-vested RSUs and outstanding warrants. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share of common stock by application of the treasury stock method, except if its impact is anti-dilutive. Under the treasury stock method, an increase in the fair market value of our common stock can result in a greater dilutive effect from potentially dilutive securities. S. Concentrations Credit Risk Financial instruments that potentially subject us to concentration of credit risk consist of cash. Our cash is held by two financial institutions in the U.S. We believe that the two financial institutions are financially sound, and accordingly, minimal credit risk exists with respect to the two financial institutions. Subsequently, in January 2024, we eliminated one of the financial institutions holding our cash to one. Supplier Risk In 2022, we entered into an exclusive license agreement (the “2022 License Agreement”) with Dong-A ST Co., Ltd. (“Dong-A”), a related party, which requires Dong-A to be the sole manufacturer for the production of DA-1241 and DA-1726. If any issues arise in the manufacturing and we are unable to arrange for alternative third-party manufacturing sources, or unable to find an alternative third party capable of reproducing the existing manufacturing method or unable to do so on commercially reasonable terms or in a timely manner, we may not be able to complete development of DA-1241 or DA-1726. T. Loss contingencies In determining whether an accrual for a loss contingency is required, we first assess the likelihood of occurrence of the future event or events that will confirm the loss. When a loss is probable (the future event or events are likely to occur) and the amount of the loss can be reasonably estimated, the estimated loss is accrued. If the reasonable estimate of the loss is a range and an amount within the range appears to be a better estimate than any other amount within the range, that amount should be accrued. However, if no amount within the range is a better estimate, the minimum amount in the range should be accrued. When a loss is reasonably possible (the chance of the future event or events occurring is more than remote but less than likely), no accrual is recognized. |
