Accounting Policies [Abstract] |
Description of Business | Description of Business On September 19, 2022, Celsion Corporation announced a corporate name change to Imunon, Inc. (“Imunon” or the “Company”) reflecting the evolution of the Company’s business focus and its commitment to developing cutting-edge immunotherapies and next-generation vaccines to treat cancer and infectious diseases. The Company’s common stock continues to trade on the Nasdaq Stock Market under the ticker symbol “IMNN.” Imunon is a fully integrated, clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. Imunon is developing its non-viral DNA technology across four modalities. The first modality, TheraPlas®, is developed for the coding of proteins and cytokines in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the coding of viral antigens that can elicit a strong immunological response. This technology may represent a promising platform for the development of vaccines in infectious diseases. The third modality, FixPlas®, concerns the application of Imunon’s DNA technology to produce universal cancer vaccines, also called tumor associated antigen cancer vaccines. The fourth modality, IndiPlas®, is in the discovery phase and will focus on the development of personalized cancer vaccines, or neoepitope cancer vaccines. The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer currently in Phase 2 development. IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company is conducting IND-enabling preclinical studies for the development of a COVID-19 booster vaccine (IMNN-101) and a treatment for the Lassa virus (IMNN-102). The Company has also initiated preclinical work to develop a Trp2 tumor associated antigen cancer vaccine in melanoma (IMNN-201). Imunon will continue to leverage these modalities and to advance the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements (“Financial Statements”) of Imunon have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and CLSN Laboratories, Inc. The Company in 2023 dissolved Celsion GmbH. All significant intercompany balances and transactions have been eliminated in consolidation. Events and conditions arising subsequent to the most recent balance sheet date through the date of the issuance of these Financial Statements have been evaluated for their possible impact on the Financial Statements and accompanying notes. No events and conditions would give rise to any information that required accounting recognition or disclosure in the Financial Statements other than those arising in the ordinary course of business.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates using historical experience and other factors, including the current economic environment. Significant items subject to such estimates are assumptions used for purposes of determining stock-based compensation, the fair value of the earn-out milestone liabilities, estimates for contingent liabilities, if any, and accounting for impairment of in-process research and development assets. Management believes its estimates to be reasonable under the circumstances. Actual results could differ significantly from those estimates.
Revenue Recognition | Revenue Recognition The Company’s sole revenue stream was related to the Hisun agreement described in Note 18, and whose contract has expired. There were no accounts receivable as of December 31, 2023 and 2022.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash on hand and investments purchased with an original maturity of three months or less. A portion of these funds are not covered by FDIC insurance.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying values of financial instruments approximate their respective fair values. Management believes that the carrying amounts of the Company’s financial instruments, including cash and cash equivalents and accounts payable approximate fair value due to the short-term nature of those instruments. Short-term investments are recorded at their estimated fair value.
Short-Term Investments | Short-Term Investments The Company classifies its investments in debt securities with readily determinable fair values as investments available-for-sale in accordance with Accounting Standards Codification (“ASC”) 320, Investments - Debt and Equity Securities. Available-for-sale securities consist of debt securities not classified as trading securities or as securities to be held to maturity. The Company has classified all of its investments as available-for-sale. Unrealized holding gains and losses on available-for-sale securities are reported as a net amount in accumulated other comprehensive gain or loss in stockholders’ equity until realized. Gains and losses on the sale of available-for-sale securities are determined using the specific identification method. The Company’s short-term investments consist of corporate bonds.
Property and Equipment | Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided over the estimated useful lives of the related assets, ranging from three to seven years, using the straight-line method. Amortization is recognized over the lesser of the life of the asset or the lease term. Major renewals and improvements are capitalized at cost and ordinary repairs and maintenance are charged against operating expenses as incurred. Depreciation expense was approximately $248,000 and $197,000 for the years ended December 31, 2023 and 2022, respectively. The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An asset is considered impaired if its carrying amount exceeds the future net undiscounted cash flows that the asset is expected to generate. If such asset is considered to be impaired, the impairment recognized is the amount by which the carrying amount of the asset, if any, exceeds its fair value determined using a discounted cash flow model. There was no impairment of property or equipment during 2023 or 2022.
Deposits | Deposits Deposits include real property security deposits and other deposits which are contractually required and of a long-term nature.
In-Process Research and Development, Other Intangible Assets and Goodwill | In-Process Research and Development, Other Intangible Assets and Goodwill During 2014, the Company acquired certain assets of EGEN, Inc. As more fully described in Note 6, the acquisition was accounted for under the acquisition method of accounting which required the Company to perform an allocation of the purchase price to the assets acquired and liabilities assumed. Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets and liabilities based on their estimated fair values as of the acquisition date.
Impairment or Disposal of Long-Lived Assets | Impairment or Disposal of Long-Lived Assets The Company assesses the impairment of its long-lived assets under accounting standards for the impairment or disposal of long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss only if its carrying amount is not recoverable through its undiscounted cash flows and measures the impairment loss based on the difference between the carrying amount and fair value. See Note 5 for information on impairment losses of its in-process research and development.
Comprehensive Income (Loss) | Comprehensive Income (Loss) ASC 220, Comprehensive Income, establishes standards for the reporting and display of comprehensive income (loss) and its components in the Company’s consolidated financial statements. The objective of ASC 220 is to report a measure of comprehensive income (loss) of all changes in equity of an enterprise that result from transactions and other economic events in a period other than transactions with owners. Comprehensive gains (losses) result from changes in unrealized gains and losses from investment in debt securities.
Research and Development | Research and Development Research and development costs are expensed as incurred. Equipment and facilities acquired for research and development activities that have alternative future uses are capitalized and charged to expense over their estimated useful lives.
Net Loss per Share of Common Stock | Net Loss per Share of Common Stock Basic and diluted net loss per common share was computed by dividing net loss for the year by the weighted average number of shares of common stock outstanding, both basic and diluted, during each period. The impact of common stock equivalents has been excluded from the computation of diluted weighted average common shares outstanding in periods where there is a net loss, as their effect is anti-dilutive. For the years ended December 31, 2023 and 2022, the total number of shares of common stock issuable upon exercise of warrants and equity awards was 1,255,642 and 988,389, respectively. For the years ended December 31, 2023 and 2022, diluted loss per common share is the same as basic loss per common share as all options and all other warrants that were convertible into shares of the Company’s common stock were excluded from the calculation of diluted earnings attributable to common stockholders per common share as their effect would be anti-dilutive.
Income Taxes | 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 tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted 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 tax rates is recognized in results of operations in the period that the tax rate change occurs. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. In accordance with ASC 740, Income Taxes, a tax position is recognized as a benefit only if it is “more likely than not” that the tax position taken would be sustained in a tax examination, presuming that a tax examination will occur. The Company recognizes interest and/or penalties related to income tax matters in the income tax expense category. As more fully discussed in Note 10, on November 28, 2023, the Company received approval from the New Jersey Economic Development Authority to sell $1.3 million of its New Jersey net operating losses (“NOLs”), recognizing a tax benefit for the year ended December 31, 2023 for the net proceeds (approximately $1.3 million) by reducing the net operating loss valuation allowance. As more fully discussed in Note 10, on November 28, 2023, the Company was notified by the New Jersey Economic Development Authority that its application was approved and the Company entered into an agreement to sell this NOL. On March 22, 2024, the Company received approximately $1.3 million upon completion of the sale of the 2023 NOLs. During 2022, the Company received approval to sell $1.6 million of its New Jersey NOLs, receiving net proceeds of approximately $1.6 million. As part of the Technology Business Tax Certificate Program sponsored by The New Jersey Economic Development Authority, emerging biotechnology companies with unused NOLs and unused research and development credits are allowed to sell these benefits to other New Jersey-based companies. During 2021, the New Jersey State Legislature increased the maximum lifetime benefit per company from $15 million to $20 million, which will allow the Company to participate in this innovative funding program in future years for up to an additional $0.4 million in net operating losses under this maximum lifetime benefit (see Note 2).
Stock-Based Compensation | Stock-Based Compensation In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation, which simplifies various aspects of accounting for share-based payments. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences and classification on the statements of cash flows. The Company recognizes the effect of forfeitures in compensation cost when they occur.
Recent Accounting Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued accounting pronouncements will not have a material impact on the Company’s consolidated financial position, results of operations, and cash flows, or do not apply to its operations. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU No. 2023-09 is effective for fiscal years beginning after December 15, 2024 and allows for adoption on a prospective basis, with a retrospective option. Early adoption is permitted. The Company is currently evaluating the impact of the ASU on the income tax disclosures within the consolidated financial statements.
