Accounting Policies [Abstract] |
Basis of Presentation and Consolidation | Basis of Presentation and Consolidation In management’s opinion, the accompanying interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the Company's financial position, results of operations and cash flows. The interim results of operations are not necessarily indicative of the results that may occur for the full year. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to instructions, rules and regulations prescribed by the U.S. Securities and Exchange Commission (“SEC”). The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these condensed consolidated financial statements are read in conjunction with the consolidated financial statements and notes included in the Company’s financial statements filed in the Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 26, 2024, and any Quarterly Reports on Form 10-Q filed thereafter. The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, LBS and Suzhou Neuralstem Biopharmaceutical Co., Ltd. All the entities are consolidated in the Company's condensed consolidated financial statements and all intercompany activity and transactions, if any, have been eliminated.
Reverse Stock Split | Reverse Stock Split On April 5, 2024, the Company effected a 1-for-15 reverse stock split of its issued and outstanding common stock (the "Reverse Stock Split"). As a result of the Reverse Stock Split, each of the Company’s stockholders received one share of common stock for every 15 shares such stockholder held immediately prior to the effective time of the Reverse Stock Split. The Reverse Stock Split affected all the Company’s issued and outstanding shares of common stock equally. The par value and authorized shares of the Company's common stock were not adjusted as a result of the Reverse Stock Split. The Reverse Stock Split also affected the Company’s outstanding stock-based awards, common stock warrants, and other exercisable or convertible securities and resulted in the shares underlying such instruments being reduced and the exercise price or conversion price being increased proportionately. Unless otherwise noted, all common stock shares, common stock per share data and shares of common stock underlying convertible preferred stock, stock-based awards and common stock warrants included in these condensed consolidated financial statements, including the exercise price or conversion price of such equity instruments, as applicable, have been retrospectively adjusted to reflect the Reverse Stock Split for all periods presented.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates, judgments, and assumptions that impact the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the balance sheet, and the reported amounts of expenses during the reporting period. The most significant estimates in the Company’s condensed consolidated financial statements relate to accrued research and development expenses and its contingent consideration obligation. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may materially differ from these estimates and assumptions.
Significant Accounting Policies | Significant Accounting Policies The Company’s significant accounting policies used in the preparation of these condensed consolidated financial statements for the three and nine months ended September 30, 2024 are consistent with those discussed in Note 2 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 26, 2024.
Reclassifications | Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. During the fourth quarter of 2023, the Company reclassified the fair value of the contingent consideration milestone payment obligation associated with the Giiant License Agreement (as defined below), including transaction related costs, in the amount of $362,000 from In-process research and development expenses to Research and development expenses at the consolidated statement of operations, which impacted amounts previously reported for the three and nine months ended September 30, 2023.
Comprehensive Loss | Comprehensive Loss Comprehensive income (loss) is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss was the same as its reported net loss for all periods presented.
Recently Issued or Adopted Accounting Pronouncements | Recently Issued or Adopted Accounting Pronouncements No new accounting pronouncements issued or adopted during the three and nine months ended September 30, 2024 that had or are expected to have a material impact on the Company’s condensed consolidated financial statements or disclosures.
