​ Accrued and Other Current Liabilities ​ In June 2024, following the Company’s decision to halt further development of AV-101, the Company announced its plan to terminate nearly all of its workforce in the coming months (the “Workforce Reduction Plan”). As of September 30, 2024, 46 individuals, or approximately 90% of the Company’s workforce, have been terminated. The affected individuals have been and will be provided severance benefits, including cash severance payments. Each affected individual’s eligibility for severance benefits is contingent upon entering into a separation agreement, which includes a general release of claims against the Company. In connection with the Workforce Reduction Plan, the Company incurred costs (in consideration of releases) of approximately $6.4 million, which are primarily one-time severance benefits, during the nine months ended September 30, 2024. The Company has paid approximately $2.4 million of severance benefits, and liabilities associated with the Workforce Reduction Plan were approximately $4.0 million as of September 30, 2024. The Company estimates that the remaining liabilities will be paid in the fourth quarter of 2024 and first quarter of 2025. ​ Accrued and other current liabilities consisted of the following (in thousands): ​
