Debt Disclosure [Abstract]  
Notes Payable Notes PayableIn connection with the closing of the IPO on February 19, 2019, convertible notes (and related accrued interest) of $11.8 million were converted into 6,825,391 shares of the Company's common stock. Certain notes automatically converted, according to their terms, into common stock. Certain holders were not permitted to convert such notes to the extent that the holders or any of its affiliates would beneficially own in excess of 4.99% of the Company’s common stock after such conversion. Due to this limitation, principal representing $47.8 thousand of these notes remained and was later converted into 273,034 shares of the Company's common stock in August and September 2019 when the conversion did not result in the holders and any of its affiliates owning more than 4.99% of the Company's outstanding common shares. All remaining debt instruments were settled at the closing of the IPO.
