Debt Disclosure [Abstract] |
DEBT | DEBT Pharmakon Loan Agreement On November 1, 2024, we entered into a loan agreement, or the Pharmakon Loan Agreement, with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership, each, a Lender, which are investment funds managed by Pharmakon Advisors, LP, and BioPharma Credit PLC, as collateral agent, that provides for a 5-year senior secured term loan facility of up to $250.0 million, divided into three committed tranches: (i) a Tranche A Loan in an aggregate principal amount of $125.0 million, or the Tranche A Loan, which was funded on November 1, 2024, or the Tranche A Closing Date; (ii) a Tranche B Loan in an aggregate principal amount of $75.0 million, or the Tranche B Loan, which is available, subject to certain limited conditions, at our option; and (iii) a Tranche C Loan in an aggregate principal amount of $50.0 million, or the Tranche C Loan, and together with the Tranche A Loan and the Tranche B Loan, collectively, the Term Loans, which is available to us upon reaching a specified trailing twelve-month RYTELO revenue milestone. The Tranche B Loan and the Tranche C Loan, once available, may be requested on or prior to December 31, 2025. A portion of the proceeds from the Tranche A Loan were used to repay, in full, all amounts owed under the Hercules Loan Agreement, which was terminated effective November 1, 2024. The remaining proceeds will be used to fund our general corporate and working capital requirements. The Term Loans mature on November 1, 2029. The Term Loans bear interest at a variable rate per annum equal to 5.75% plus the three-month Secured Overnight Financing Rate, or SOFR, with a SOFR floor of 3.00%. As of the inception date, the interest rate applicable to the Tranche A Loan was 10.32%. As of September 30, 2025, the applicable interest rate was 10.04%. Interest is due and payable quarterly on the last day of each quarter with the first payment due on December 31, 2024. The Pharmakon Loan Agreement requires we pay an amount equal to 2.50% of the Lenders’ total committed amount to fund the Term Loans, payable with respect to each Term Loan on the funding date of such Term Loan. We may elect to prepay the Term Loans in part or in whole prior to the Maturity Date with such prepayments being subject to a prepayment premium equal to the principal amount so prepaid multiplied by 3% if made prior to the 3rd anniversary of the funding date of the applicable Term Loan, 2% if made on or after the 3rd anniversary of the funding date of the applicable Term Loan but prior to the 4th anniversary of the funding date of the applicable Term Loan, and 1% if made on or after the 4th anniversary of the funding date of the applicable Term Loan but prior to the Maturity Date. In addition to the prepayment premium, prepayments of any Term Loan prior to the 2nd anniversary of the funding date of such Term Loan are subject to a make-whole amount equal to the sum of all interest that would have accrued through such 2nd anniversary. Our obligations under the Pharmakon Loan Agreement are secured by substantially all of our assets, including our intellectual property. Certain of our subsidiaries may, from time to time after the Tranche A Closing Date, be required to guarantee our obligations under the Pharmakon Loan Agreement and, in connection with such guarantee, pledge substantially all of their assets, including intellectual property, to secure such guarantee. The Pharmakon Loan Agreement contains customary affirmative and restrictive covenants and representations and warranties. We are bound by certain affirmative covenants setting forth actions that are required during the term of the Pharmakon Loan Agreement, including, without limitation, certain information delivery requirements, obligations to maintain certain insurance, and certain notice requirements. There are no financial covenants. Additionally, we are bound by certain restrictive covenants setting forth actions that are not permitted to be taken during the term of the Pharmakon Loan Agreement, including, without limitation, (i) selling or disposing of assets, (ii) amending, modifying or waiving our rights under material agreements, (iii) consummating change in control transactions unless all amounts becoming due under the Loan Agreement are paid in full immediately upon (and concurrent with) the consummation of any such change in control transaction, (iv) incurring additional indebtedness, (v) incurring non-permitted liens or encumbrance on our or our subsidiaries’ assets, (vi) paying dividends or making any distribution or payment on or redeeming, retiring or purchasing any equity interests, and (vii) making payments on subordinated indebtedness, in each case, subject to specified exceptions. The Pharmakon Loan Agreement also contains the following events of default: (i) failure to pay principal, interest and other amounts when due, (ii) the breach of the covenants under the Loan Agreement, (iii) the occurrence of a material adverse change or the occurrence of a withdrawal event in respect of RYTELO, (iv) certain attachments of the credit parties assets and restraints on their business, (v) certain insolvency, liquidation, bankruptcy or similar events, (vi) certain cross-default of third-party indebtedness and royalty revenue contracts, (vii) the failure to pay certain judgments, (viii) material misrepresentations, (ix) the loan documents ceasing to create a valid security interest in a material portion of the collateral, (x) the occurrence of certain ERISA events, and (xi) the occurrence of a default under any subordination or intercreditor agreement, in each case subject to the grace periods, cure period and thresholds as specified in the Pharmakon Loan Agreement. Upon the occurrence and during the continuance of an event of default, the Lenders may, among other things, accelerate our obligations under the Pharmakon Loan Agreement (including all obligations for principal, interest and any applicable make-whole and prepayment premiums); provided that upon an event of default relating to certain insolvency, liquidation, bankruptcy or similar events, all outstanding obligations will be immediately accelerated.

Liabilities Related to Sale of Future Royalties On November 1, 2024, we entered into a revenue participation right purchase and sale agreement, or the Royalty Pharma Agreement, with Royalty Pharma Development Funding, LLC, or Royalty Pharma. Pursuant to the Royalty Pharma Agreement, we received an upfront payment of $125.0 million, or the Purchase Price, in exchange for which Royalty Pharma obtained the right, or the Revenue Participation Right, to receive certain amounts calculated as a percentage of future U.S. net sales of RYTELO for each calendar quarter, or Royalty Payments, during the term contemplated by the Royalty Pharma Agreement. Specifically, the revenue participation rate commences at 7.75% for annual U.S. net sales of up to and equal to $500.0 million declining to 1.0% for annual U.S. net sales exceeding $1.0 billion until the date when the aggregate Royalty Payments equal or exceed 1.65 times the Purchase Price, if this occurs by June 30, 2031, or the date when the aggregate Royalty Payments equal or exceed 2.0 times the Purchase Price. In addition, we have the option to repurchase all of the Revenue Participation Right from Royalty Pharma for a purchase price of equal to the Buy-Out-Payment, as defined below, if we enter into a definitive agreement to consummate a change of control, or Buy-Back Option. “Buy-Out Payment” means an amount equal to (a) 1.65 times the Purchase Price minus the aggregate Royalty Payments as of the change of control, if the change of control occurs on or prior to December 31, 2027, or (b) 2.0 times the Purchase Price minus the aggregate Royalty Payments as of the change of control, if the change of control occurs after December 31, 2027. We accounted for the Royalty Pharma Agreement as a financing liability, primarily because it has significant continuing involvement in generating the future revenue on which the Royalty Payments are based. The liability related to Revenue Participation Right and the related interest expense are measured based on our current estimate of the timing and amount of expected future Royalty Payments expected to be paid over the estimated term of the Royalty Pharma Agreement The liability is amortized using the effective interest rate method, resulting in recognition of interest expense over the estimated term of the agreement. We have determined the fair value of the liability related to the sale of future royalties is based on our current estimates of future royalties expected to be paid to Royalty Pharma over the life of the arrangement, which are considered Level 3. The following table shows the activity within the liability related to sale of future royalties during the nine months ended September 30, 2025:
(in thousands) |  | Liability Related to Sale of Future Royalties
Carrying value of liability related to sale of future royalties at December 31, 2024 |  | $ | 124,793 |
Interest expense recognized |  | 15,043 |
Royalty payments |  | 10,503 |
Carrying value of liability related to sale of future royalties at September 30, 2025 |  | $ | 129,333 |
Embedded Derivatives The conditional exercisable call option related to the event of default is considered to be an embedded derivative which is required to be bifurcated and accounted for as a separate financial instrument. In the periods presented, the value of the embedded derivative is not material and therefore, no amount has been recognized. If an event of default becomes more probable than is currently estimated, then the embedded derivative could become material in future periods and would be recognized as a separate financial instrument at that time. The embedded derivatives are classified within Level 3 of the fair value hierarchy due to the use of significant unobservable inputs.
