Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn May 4, 2020, the Company announced its intent to undertake a program to reduce its workforce as part of the Company’s efforts to respond to the COVID-19 pandemic and ensure longer-term financial stability for the Company in light of the ongoing economic challenges resulting from COVID-19 and its impact on the Company’s business (the “Program”). The Program involves the termination of approximately 60 employees, representing 13% of the Company’s headcount. Under the Program, the Company estimates that it will incur charges of approximately $1.8 million to $2.2 million, which will be related to employee severance and benefits costs, all of which are cash expenditures, the majority of which the Company expects to incur in the second quarter of 2020. In addition, as part of its cost reductions in light of the COVID-19 pandemic, the Company has implemented reductions in base salary for its employees, effective May 16, 2020, consisting of a 30% reduction for the Company’s Chief Executive Officer, 25% reduction for the Company’s Chief Financial Officer, 20% reduction for members of the Company’s executive leadership team, and tiered reductions of 10-15% for other employees with salaries above $100,000, which the Company anticipates will last at least six months, and will be re-evaluated at that time. Members of the Company’s board of directors have also voluntarily agreed to forego 50% of their cash compensation for the duration of the employee salary reductions.
