Fair Value Disclosures [Abstract] |
Fair Value Measurements | 5. Fair Value Measurements Fair Value of Financial Instruments The Company has certain financial assets and liabilities recorded at fair value which have been classified as Level 1, 2 or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements. • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities measured at fair value on a recurring and nonrecurring basis as of September 30, 2023 and December 31, 2022 are as follows:

Cash equivalents |  | $ | 38,058 |  |  | $ | 38,058 |  |  | $ | — |  |  | $ | — |
The cash equivalents represent demand deposit accounts and deposits in a short-term United States treasury money market mutual fund quoted in an active market and classified as a Level 1 asset. There have been no changes to the valuation methods during the three or nine months ended September 30, 2023. We had no financial assets or liabilities that were classified as Level 2 or Level 3 during the three or nine months ended September 30, 2023. Fair Value of Non-Financial Instruments The Company evaluates assets for impairment whenever events or changes in circumstances indicate that indicators of impairment exist. In those evaluations, the Company compares estimated future undiscounted cash flows generated by each asset (or asset group) to the carrying value of the asset (or asset group) to determine if an impairment charge is required. If the undiscounted cash flows test fails, the Company estimates the fair value of the asset (or asset group) to determine the impairment. Following the Company’s announced strategic reprioritization on August 14, 2023, the Company determined that changes in the intended use of certain property and equipment represented an indicator of impairment, resulting in an impairment charge of $1.0 million, which was primarily related to lab equipment of $0.9 million and leasehold improvements of $0.1 million. In addition, the Company determined certain prepaid expense balances to be impaired given the Company’s strategic reprioritization, and therefore, has recorded an impairment charge of $0.1 million related to prepaid expenses and other current assets, which is recorded in research and development expenses within the condensed statement of operations. On November 9, 2023, the Company executed an agreement to sell laboratory equipment for gross proceeds of $1.5 million. As of September 30, 2023, the laboratory equipment had a carrying value of $1.5 million recorded within Property and Equipment, net in the condensed balance sheet.
