| Nature of Business | 1. Nature of Business Nature of Operations Cyclerion Therapeutics, Inc. (“Cyclerion”, the “Company” or “we”) became an independent public company on April 1, 2019 after Ironwood Pharmaceuticals, Inc., or Ironwood, completed a tax-free spin-off of its novel soluble guanylate cyclase ("sGC") business, which we refer to herein as the "Separation". Cyclerion has one employee as of June 30, 2024. At inception, Cyclerion was a biopharmaceutical company focused on the treatment of serious diseases with sGC stimulators in both the central nervous system ("CNS") and the periphery. The nitric oxide ("NO") sGC cyclic guanosine monophosphate ("cGMP") signaling pathway is a fundamental mechanism that precisely controls key aspects of physiology throughout the body. The NO-sGC-cGMP pathway regulates diverse and critical biological functions in both the CNS and the periphery and has been successfully targeted with several drugs. Praliciguat is an orally administered, once-daily systemic sGC stimulator. On June 3, 2021, Cyclerion entered into a license agreement (as defined below) with Akebia Therapeutics Inc. (“Akebia”) relating to the exclusive worldwide license to Akebia of the Company's rights to the development, manufacture, medical affairs and commercialization of pharmaceutical products containing praliciguat and other related products and forms thereof enumerated in such agreement. Cyclerion is eligible to receive up to $ 585 million in total potential future development, regulatory, and commercialization milestone payments. Cyclerion is also eligible to receive tiered, sales-based royalties ranging from single-digit to high-teen percentages and subject to reduction upon expiration of patent rights or the launch of a generic product. Olinciguat is a Phase 2 orally administered, once-daily, vascular sGC stimulator that Cyclerion intends to out-license to an entity with strong cardiovascular and/or cardiopulmonary capabilities. Zagociguat is a clinical-stage CNS-penetrant sGC stimulator that has shown rapid improvement in cerebral blood flow, functional brain connectivity, brain response to visual stimulus, cognitive performance, and biomarkers associated mitochondrial function and inflammation in clinical studies. CY3018 is a CNS-targeted sGC stimulator that preferentially localizes to the brain and has a pharmacology profile that suggests its potential for the treatment of neuropsychiatric diseases and disorders. On July 28, 2023, the Company sold zagociguat and CY3018 to Tisento Therapeutics, Inc. (“Tisento”), a newly formed private company focused on their development, in exchange for $ 8.0 million in cash consideration, $ 2.4 million as reimbursement for certain operating expenses related to zagociguat and CY3018 for the period between signing and closing of the transaction, and 10 % of all of Tisento’s parent’s outstanding equity securities. See “Asset Purchase Agreement” and “Note 4” below. Cyclerion is actively evaluating other activities aimed at enhancing shareholder value, which may potentially include collaborations, licenses, mergers, acquisitions and/or other targeted investments. The Company has shifted its strategy to identify, non-sGC stimulator assets within the CNS therapeutic area to build a new portfolio. If the Company identifies and acquires or licenses suitable new assets, the Company will seek to develop the new assets and retain contract research, development and manufacturing organizations for these specific purposes. Additionally, Cyclerion plans to seek to raise funds for further research and development activities associated with any new assets. The Company’s goal is to find the best combination of capital, capabilities, and transactions that will enable the advancement of current and any future assets the Company may acquire for patients in a way that maximizes shareholder value. Cyclerion GmbH, a wholly owned subsidiary, was incorporated in Zug, Switzerland on May 3, 2019. The functional currency is the Swiss franc. The liquidation process for Cyclerion GmbH has been concluded and the subsidiary was de-registered in May 2024. Cyclerion Securities Corporation, a wholly owned subsidiary, was incorporated in Massachusetts on November 15, 2019 and was granted securities corporation status in Massachusetts for the 2019 tax year. Cyclerion Securities Corporation has no employees. Stock Purchase Agreement In March 2023, the Company entered into a stock purchase agreement with the Company's former Chief Executive Officer (the “Former CEO”) pursuant to which he invested $ 5 million in cash for 225,000 shares of common stock and 351,037 shares of Series A Convertible Preferred Stock of the Company at a price of $ 8.68 per share (after giving effect to the 1-for-20 reverse stock split the Company implemented on May 15, 2023). Such Series A Convertible Preferred Stock is convertible into shares of the Company's common stock on a one-to-one basis. The closing of the equity investment took place on May 19, 2023, and (to comply with Nasdaq listing requirements) the Company's shareholders approved such convertibility on July 19, 2023. Asset Purchase Agreement On May 11, 2023, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with an investor group that included the Former CEO, JW Celtics Investment Corp and JW Cycle Inc. which subsequently changed their names to Tisento Therapeutics Holdings Inc. (“Tisento Parent”) and Tisento. Upon the closing on July 28, 2023, of the transactions contemplated by the Asset Purchase Agreement, the Company sold to Tisento specified assets relating to the Company’s zagociguat and CY3018 programs (the "Transferred Assets") and Tisento assumed certain liabilities relating thereto, including, but not limited to (i) liabilities, costs and expenses arising after the date of the Asset Purchase Agreement relating to the employment of certain Cyclerion employees and the conduct of certain preclinical and clinical trial activities prior to the closing of the transactions contemplated by the Asset Purchase Agreement, and (ii) liabilities relating to such assets to the extent relating to the period after the closing of the transaction. In consideration for such sale and assumption, at such closing the Company received proceeds of $8.0 million as cash consideration, $2.4 million as reimbursement for certain operating expenses related to such assets for the period between signing and closing of the Asset Purchase Agreement, and shares of common stock of Tisento Parent comprising 10% of the then issued and outstanding equity securities of Tisento Parent immediately following such closing, subject to certain protections against dilution. Reverse Stock Split On May 15, 2023, the Company filed Articles of Amendment to the Company's Restated Articles of Organization with the Secretary of Commonwealth of Massachusetts to effect a 1-for-20 reverse stock split of the Company's issued and outstanding shares of common stock. The reverse stock split was reflected on the Nasdaq Capital Market beginning with the opening of trading on May 16, 2023. All share amounts and per share amounts disclosed in this Quarterly Report on Form 10-Q have been adjusted retroactively to reflect the reverse stock split for all periods presented. At-the-Market Offering On July 24, 2020, the Company filed a Registration Statement on Form S-3 (the “Shelf”). On September 3, 2020, the Company entered into a Sales Agreement (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) with respect to an at-the-market offering (the “ATM Offering”) under the Shelf. Under the ATM Offering, the Company could offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $ 50.0 million through Jefferies as its sales agent. The Company agreed to pay Jefferies cash commissions of 3.0 percent of the gross proceeds of sales of common stock which could be sold under the Sales Agreement. Prior to January 1, 2022, the Company sold 3,353,059 shares of its common stock for net proceeds of $ 12.5 million under the ATM Offering, since entering into the Sales Agreement. No shares of common stock have been issued or sold under the ATM Offering from January 1, 2022 to July 31, 2023. The Shelf expired in July 31, 2023. Due to the current market value of the Company's publicly traded common stock held by non-affiliates, the Company's ability to raise future funding though a shelf offering will be limited. Basis of Presentation The condensed consolidated financial statements and the related disclosures are unaudited and have been prepared in accordance with accounting principles generally accepted in the U.S. Additionally, certain information and footnote disclosures normally included in the Company’s annual financial statements have been condensed or omitted. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, which was filed with the Securities and Exchange Commission on March 5, 2024. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all normal recurring adjustments considered necessary for a fair presentation of the Company’s financial position and the results of its operations for the interim periods presented. The results of operations for the three and six months ended June 30, 2024 and 2023 are not necessarily indicative of the results that may be expected for the full year or any other subsequent interim period. The condensed consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries, Cyclerion GmbH, and Cyclerion Securities Corporation. All significant intercompany accounts and transactions have been eliminated in the preparation of the accompanying condensed consolidated financial statements. Going Concern At each reporting period, in accordance with Accounting Standards Codification ("ASC") 205-40, Going Concern, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company’s evaluation entails analyzing prospective operating budgets and forecasts for expectations of the Company’s cash needs and comparing those needs to the current cash and cash equivalent balances. The Company is required to make certain additional disclosures if it concludes substantial doubt exists and it is not alleviated by the Company’s plans or when its plans alleviate substantial doubt about the Company’s ability to continue as a going concern. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that these condense consolidated financial statements are issued. In performing its analysis, management excluded certain elements of its operating plan that cannot be considered probable. Under ASC 205-40, the future receipt of potential funding from future partnerships, equity or debt issuances, certain cost reduction measures and the potential milestones from the Akebia agreement cannot be considered probable at this time because these plans are not entirely within the Company’s control and/or have not been approved by the Board of Directors as of the date of these condensed consolidated financial statements. The Company expects that its cash and cash equivalents as of June 30, 2024 , will be sufficient to fund operations through mid-2025, however the Company will need to obtain additional funding to sustain operations as it expects to continue to generate operating losses for the foreseeable future. The Company's expectation to generate negative operating cash flows in the future and the need for additional funding to support its planned operations, raise substantial doubt regarding the Company’s ability to continue as a going concern. Management's plans to alleviate the conditions that raise substantial doubt include reduced spending, and the pursuit of additional capital. Management has concluded the likelihood that its plan to successfully obtain sufficient funding, or adequately reduce expenditures, while reasonably possible, is less than probable. Accordingly, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above. |
