Common Stock Warrant Liability [Text Block]	Note 11 – Common Stock Warrant Liability In July 2024, we completed two private placements of Series C Preferred Stock and common stock warrants, or the July 2024 Warrants (Refer to Note 13, “Mezzanine Equity and Stockholders' Equity - Accounting for the First and Second Private Placements” for additional details). The July 2024 Warrants were exercisable upon the six month and one day anniversary of the issuance date, or the Initial Exercisability Date, and expire on the fifth anniversary of the Initial Exercisability Date and had an initial exercise price of $205.50 per share, subject to customary adjustments. The July 2024 Warrants are considered a freestanding financial instrument as they are separable and legally detachable from the Series C Preferred Stock. The July 2024 Warrants have been classified as a liability in the Company’s condensed consolidated balance sheet because they include a put option election available to the holders that is contingently exercisable if the Company enters into a change of control transaction, or the Change of Control Put. If the Change of Control Put is exercised by the holder of a July 2024 Warrant, they may elect to receive cash as determined by the Black Scholes pricing model, based on terms and timing specified in the July 2024 Warrants. The potential for a cash settlement for the July 2024 Warrants is outside the control of the Company, and in accordance with U.S. GAAP, required the July 2024 Warrants to be treated as financial liabilities measured at fair value through profit or loss. The July 2024 warrants had an initial fair value of $10.8 million upon issuance and were remeasured to a fair value of $0.3 million as of December 31, 2024. For the three and nine months ended September 30, 2025, the change in the estimated fair value of the July 2024 warrants was $0.1 million and $0.3 million, respectively, and was recorded in the condensed consolidated statement of operations.
