Leases, Operating [Abstract] |
Leases | 8. Leases In April 2022, the Company modified its real estate lease agreement executed on December 15, 2020 with MD Anderson for office space in Houston, Texas, which reduced the Company's leased space from 18,111 square feet to 3,228 square feet. As a result, the associated lease liability and right-of-use asset were remeasured to $0.4 million based on revised lease payments. A gain of $0.1 million was recorded on the lease modification during the second quarter of 2022. On April 19, 2023, the Company terminated its office lease in Boston, Massachusetts, which was set to expire on August 31, 2026. In connection with the termination, the Company also assigned to the landlord its sub-sublease of the Boston office space, which had a term expiring on June 30, 2025 with an option to extend through July 31, 2026. Termination costs for the Boston office lease were $0.2 million. A gain of $0.2 million was recorded on the lease termination during the second quarter of 2023. In August 2023, in accordance with the lease agreement executed on December 15, 2020, the Company notified MD Anderson, as landlord, of its intention to terminate office space of 3,228 square feet in Houston, Texas. As a result, the associated lease liability and right-of-use asset were remeasured to $19 thousand, reflecting the revised lease payments and term end date of November 2023. On November 1, 2023, the Company and MD Anderson, as landlord, agreed to mutually terminate the leases dated October 15, 2019 and April 7, 2020, which represent office space totaling 14,037 square feet. The termination will be effective November 15, 2023 and the Company has agreed to make a final payment of $0.1 million to the landlord.
