In August 2021, the Company entered into a service agreement (the “TRV service agreement”) with Third Rock Ventures, LLC (“TRV”), a holder of more than 5% of the Company’s outstanding capital stock, under which TRV provides consulting services to the Company. For the three months ended March 31, 2026 and 2025, the Company incurred no fees under the TRV service agreement. There were no expenses related to TRV in accrued expenses and other current liabilities on the Company’s condensed balance sheets at March 31, 2026, or December 31, 2025.
