11. LEASES

We have a sublease agreement with Atara entered in October 2022 to sublease an office space located in South San Francisco, California. Subject to the terms of the sublease agreement, the lease term commenced in November 2022 and shall expire in May 2025. This leased facility is currently held as our new Headquarters following the expiration of our previous leased facility in January 2023. The weighted average remaining term of our leases as of December 31, 2023 was 1.42 years.

We previously leased our prior headquarter space located in South San Francisco, California with Healthpeak Properties, Inc. (formerly known as HCP BTC, LLC), and had a sublease agreement with an unrelated third-party to sublet a portion of the leased facility. Both the lease and the sublease expired in January 2023.
