Subsequent Events [Abstract]
Subsequent Events	23. Subsequent Events In February 2021, we completed an underwritten public offering of 10,575,513 shares of our common stock, including the exercise in full by the underwriters of their option to purchase up to an additional 1,344,743 shares of common stock at a public offering price of $13.00 per share. The aggregate gross proceeds from the offering, before deducting underwriting discounts and commissions and offering expenses were approximately $137.5 million. In connection with the offering, we also entered into a stock purchase agreement with certain existing investors for $15.0 million of shares of our common stock at a price per share equal to the public offering price, with an initial closing for certain investors held simultaneously with the closing of the offering and a subsequent closing for certain additional investors.
