Third Rock Ventures

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 and six months ended June 30, 2025, the Company incurred no fees under the TRV service agreement. For the three and six months ended June 30, 2024, under the TRV service agreement, the Company incurred fees of $0.1 million which were

recorded within general and administrative expenses in the Company’s condensed statements of operations and comprehensive loss. As of December 31, 2024, $0.1 million of expense related to TRV was recorded in accrued expenses and other current liabilities. There were no expenses related to TRV in accrued expenses and other current liabilities on the Company’s condensed balance sheets at June 30, 2025.

The Company’s former interim Chief Medical Officer, and also a member of the Company’s board of directors, is affiliated with TRV (the “TRV Board Member”). The TRV Board Member did not receive any cash compensation from the Company for his service as its interim Chief Medical Officer, as his services were provided to the Company through the TRV service agreement. The TRV Board Member ceased serving as interim Chief Medical Officer in September 2024. In December 2024, the Company entered into a separate consulting agreement with the TRV Board Member, which includes cash compensation to be paid directly to the TRV Board member.

During the three and six months ended June 30, 2025, total fees incurred related to the TRV Board Member’s consulting services were immaterial and $0.1 million, respectively. As of June 30, 2025, outstanding accounts payable to the TRV Board Member for consulting services was immaterial.

For the three and six months ended June 30, 2024, the fees attributed to consulting services provided by the TRV Board Member as the interim Chief Medical Officer were immaterial and $0.1 million, respectively. Additionally, as compensation for his services as the Company's interim Chief Medical Officer, the Company granted him options to purchase 23,227 shares of common stock during the six months ended June 30, 2024 at an exercise price of $2.76 per share.
