Subsequent Events [Abstract]
Subsequent Events	16. Subsequent Event On August 8, 2023, the board of directors approved a stock option repricing (the Option Repricing) to be effective on August 14, 2023 (the Effective Date) in accordance with the terms of the Company’s 2015 Stock Incentive Plan and 2018 Plan (together, the Plans). Pursuant to the Option Repricing, the exercise price of each stock option previously granted under the Plans, totaling 6,431,077 options, will be amended to reduce the exercise price of such options to the closing price of the Company’s common stock on the Nasdaq Global Market on the Effective Date. Under the terms of the Option Repricing, a repriced option will revert to its original exercise price if, prior to the one year anniversary of the Effective Date, (a) the option holder’s employment is terminated by the Company with cause or by the option holder or (b) the option is exercised. The repriced options will retain their existing terms and conditions as set forth in the Plans and applicable award agreements. In addition, as of the Effective Date, the Company will issue 1,418,043 options to purchase shares of common stock under the 2018 Plan to eligible employees who held inducement awards as of August 8, 2023. These new options will be issued to eligible employees because their inducement awards granted under Nasdaq Listing Rule 5635(c)(4) are not eligible for repricing. The prior inducement awards will remain outstanding under their original terms. The Company expects to record the impact of the Option Repricing in the quarter ending September 30, 2023.
