| Related-Party Transactions | 14. Related-Party Transactions In August 2023, contemporaneously with the closing of the Series C Offering, the Company entered into several amended and restated royalty participation agreements (the “Amended and Restated Royalty Agreements”) with certain of its investors, co-founders, former directors, and executive officers, none of whom are Series C New Investors. No consideration was received as part of the Amended and Restated Royalty Agreements. Pursuant to the Amended and Restated Royalty Agreements, the Company is obligated to pay royalties to all of the holders in an aggregate amount up to 2.75% on net sales arising from LB-102 worldwide through December 31, 2035. Thereafter, the Company is obligated to pay royalties to such holders in an aggregate amount up to 3.25% in perpetuity. Net sales are defined in these agreements as the gross payments received on total commercial sales of LB-102 less certain standard deductions, whether received by the Company or any licensee of LB-102. As of December 31, 2025, certain former and current officers of the Company and their affiliates held 1.13% of the future royalties. |
