Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesThere was no provision for income taxes for the three and nine months ended September 30, 2021 and 2020, because the Company has incurred annual operating losses since inception. At September 30, 2021, the Company continues to conclude that it is not more likely than not that the Company will realize the benefit of its deferred tax assets due to its history of losses. Accordingly, a full valuation allowance has been applied against the net deferred tax assets.
