Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Events In January 2022, we completed an underwritten public offering in which we issued 2,500,000 shares of our common stock at a price of $20.00 per share, and pre-funded warrants to purchase 2,500,000 shares of our common stock at a price of $19.999 per underlying share. We received approximately $93.5 million in net proceeds after deducting underwriting discounts and commissions and other estimated offering expenses payable by us. In February 2022, the underwriters exercised their option to purchase an additional 750,000 shares of common stock, and we received approximately $14.1 million in additional net proceeds after deducting underwriting discounts and commissions.
