Leases [Abstract] |
Leases | Leases Operating Leases In July 2021, the Company signed an operating lease for office and laboratory space in Boston, Massachusetts (the “Boston Lease”). The Boston Lease commenced in February 2022 with the term set to expire in February 2030. The Boston Lease has rent payments escalating annually, which total $11.1 million in the aggregate. As a result, at the commencement of the Boston Lease, the Company recognized a ROU lease asset of $8.0 million with a corresponding lease liability of $8.0 million based on the present value of the minimum rental payments. In addition, the Company will make payments for operating expenses and real estate taxes. In June 2023, the Company secured a letter of credit for the deposit on the Boston Lease and has a deposit in the amount of $0.7 million, which was reported as restricted cash, noncurrent on the consolidated balance sheets as of December 31, 2024 and 2023. As part of the Merger Agreement, the Company also assumed a lease for clinical and regulatory space in Newton, Massachusetts, comprising approximately 6,157 square feet for approximately $0.2 million per year, under a non-cancelable operating lease that expired on June 30, 2024. Lease expense for all leases for the years ended December 31, 2024 and 2023 was $1.5 million and $1.5 million, respectively.
