Restructuring and Related Activities [Abstract]

13. RESTRUCTURING AND RELATED CHARGES

In December 2022, the Company began implementing a restructuring plan to reduce operating costs primarily associated with a reduction in the Company's workforce (the “Restructuring”).

In connection with the Restructuring, the Company incurred expenses within research and development and general and administrative expenses of $0.2 million during the three months ended March 31, 2023. These costs primarily related to one-time termination benefits and ongoing benefit arrangements, both of which included severance payments and extended benefits coverage support and were contingent upon the impacted employees’ execution and non-revocation of separation agreements. Aggregate costs in connection with the Restructuring also included certain contract termination costs.

The following table summarizes the accrued liabilities activity recorded in connection with the Restructuring, including the reduction in workforce in December 2022 and related activities as of March 31, 2023 (in thousands):
