| Debt Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Loan and Security Agreement | Loan and Security Agreement On March 16, 2020, the Company and Rockwell Transportation, Inc., as Borrowers, entered into a Loan and Security Agreement (the "Loan Agreement") with Innovatus, as collateral agent and the lenders party thereto, pursuant to which Innovatus, as a lender, agreed to make certain term loans to the Company. In connection with each funding of the Term Loans, the Company issued to Innovatus a warrant (each a “Warrant”, and together the “Warrants”) to purchase a number of shares of the Company’s common stock equal to 3.5% of the principal amount of the relevant Term Loans funded divided by the exercise price. In connection with the first tranche of the Term Loans, the Company issued a Warrant to Innovatus, exercisable for an aggregate of 4,338 shares of the Company’s common stock at an exercise price of $181.50 per share. The Warrant may be exercised on a cashless basis and is immediately exercisable through the seventh anniversary of the applicable funding date. The number of shares of common stock for which the Warrant is exercisable and the associated exercise price are subject to certain proportional adjustments as set forth in such Warrant. The Company evaluated the warrant under ASC 470, Debt, and recognized an additional debt discount of approximately $0.5 million based on the relative fair value of the base instruments and warrants. The Company calculated the fair value of the Warrant using the Black-Scholes model. On January 2, 2024, the Company entered into the Third Amendment to and Restatement of the Loan and Security Agreement (the "Third Amendment") with Innovatus, dated January 1, 2024 (the "Effective Date"). The Third Amendment provides for the continuation of term loans initially borrowed under the Loan Agreement amounting to $8.0 million as of January 1, 2024. The Company will make interest-only payments on the Term Loans for 36 months as certain conditions in the Third Amendment were met. The Company will make equal monthly payments of principal, together with applicable interest, in arrears, starting February 1, 2027. The Term Loans will mature on January 1, 2029. Effective on January 1, 2024, the Term Loans bear interest equal to the sum of (i) the greater of (a) Prime Rate (as defined in the Third Amendment) and (b) 7.50% plus (ii) 3.50%. At the Company's option, 2.00% of the interest due on any applicable interest payment date during the interest-only period may be paid in-kind by adding such amount to the then outstanding principal balance of the Term Loans. The Company also owes an additional fee equal to 4.375% of the funded amount of the Term Loans, or $1.0 million (such additional fee, the "Final Fee") at maturity. The Company is accreting up to this Final Fee premium with a charge against interest expense on the accompanying condensed consolidated statements of operations. The Term Loans may be voluntarily prepaid in full (but not partially) at any time, upon at least business days’ prior notice. In connection with any voluntary prepayment or satisfaction of the Term Loans prior to the maturity date (including any acceleration), the Company will pay all accrued and unpaid interest and all other amounts due in connection with the Term Loans, together with (x) a prepayment fee (the “Prepayment Fee”) equal to: (i) 1.0% of the principal amount of the Term Loans prepaid if the payment is made after January 1, 2026 but on or before January 1, 2027; or (ii) 0% of the principal amount of the Term Loans prepaid if the payment is made after January 1, 2027 through maturity, and (y) the Final Fee. The Term Loans will be mandatorily prepaid upon a change in control of the Company, or upon any early termination/acceleration of the Term Loans. In the event of a mandatory prepayment of the Term Loans, the Company shall be required to pay the Prepayment Fee (if applicable), as well as the Final Fee. The Third Amendment was treated as a modification for accounting purposes. The Third Amendment contains various financial covenants and customary representations and warranties and affirmative and negative covenants, subject to exceptions as described in the Third Amendment. The Company's ability to comply with the covenants under the Third Amendment may be adversely affected by events beyond its control. If the Company is unable to comply with the covenants under the Third Amendment, it would pursue all available cure options in order to regain compliance. However, the Company may not be able to mutually agree with Innovatus on appropriate remedies to cure a future breach of a covenant, which could give rise to an event of default. As of June 30, 2026, the Company was in compliance with all covenants under the Third Amendment. In connection with the execution of the Third Amendment, on January 2, 2024, the Company issued a warrant to purchase 19,109 shares of the Company’s common stock. The warrant is equity-classified with a fair value of $0.2 million at issuance, which was treated as a debt issuance cost and is being amortized through interest expense over the remaining contractual term of the Term Loans. For additional information, see Note 11. The effective interest rate used to amortize the debt issuance cost relating to these warrants is 11.0% as of June 30, 2026. As of June 30, 2026, the outstanding balance of the Term Loans was $9.0 million, net of aggregate unamortized issuance costs, discounts and premiums of $0.5 million. For both of the six months ended June 30, 2026 and 2025, interest expense, including paid-in-kind interest, amounted to $0.5 million. The Loan Agreement is secured by all assets of the Company and Rockwell Transportation, Inc. and contains customary representations and warranties and covenants, subject to customary carve outs, and initially included financial covenants related to liquidity and sales of Triferic. The following table reflects the schedule of principal payments on the Term Loans as of June 30, 2026 (table in thousands):
