Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Events On March 12, 2021, we entered into a Capital On Demand™ Sales Agreement (Sales Agreement) with JonesTrading Institutional Services, LLC (Sales Agent), to provide for the offering, issuance and sale of up to an aggregate amount of $75.0 million of our common stock from time to time in “at-the-market” offerings under the 2021 Shelf Registration Statement and subject to the limitations thereof. We agreed to pay to the Sales Agent cash commissions of 3.0% of the aggregate gross proceeds of sales of common stock under the Sales Agreement. As of June 30, 2022, no shares were sold under the Sales Agreement. Subsequent to the end of the quarter, we sold an aggregate of 2,611,723 shares of our common stock at a price per share of $17.23 to two healthcare-focused institutional investors for anticipated gross proceeds of approximately $45.0 million.
