Line of credit facility, description	In May 2021, the parties further amended the Loan Agreement (as amended, the “2021 Loan Agreement”). The 2021 Loan Agreement increased the Term A Loan Facility to up to $20.0 million, which was fully drawn as of December 2021. The Term B Loan Facility of up to $5.0 million was available to be drawn upon on achievement of certain additional milestones, on or before September 30, 2022, which expired unused.	In April 2020, the Company entered into a Loan and Security Agreement, (the “Loan Agreement”) with the lenders referred to therein, and Silicon Valley Bank (“SVB”), as collateral agent. The Loan Agreement provided for (i) a secured term A loan facility (the “Term A Loan Facility”) of up to $10.0 million and (ii) a secured term B loan facility (the “Term B Loan Facility”) of up to $5.0 million that became available upon the satisfaction of certain milestones, each of which was available to be drawn through May 31, 2021. The term loan is secured by certain assets of the Borrowers (as defined in the Loan Agreement), including substantially all of the assets of the Company, excluding the Company’s intellectual property. The term loan contains customary representations, warranties, affirmative covenants and also certain restrictive covenants.
