Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and contingencies: (a) Asset purchase agreement with 1st Order Pharmaceuticals, Inc. (“1st Order”): In April 2017, the Company acquired azetukalner from 1st Order pursuant to an asset purchase agreement. In August 2020, the Company and 1st Order amended the asset purchase agreement to amend certain definitions in the agreement and to modify the payment schedule for certain milestones. Through December 31, 2024, the Company has paid $2,000 based on progress against these milestones. Future potential payments to 1st Order include up to $6,000 in regulatory milestones. There are no royalty obligations to 1st Order. (b) Guarantees and indemnifications: The Company has entered into license and research agreements with third parties that include indemnification provisions that are customary in the industry. These indemnification provisions generally require the Company to compensate the other party for certain damages and costs incurred as a result of third-party claims or damages arising from these transactions. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds commercial and product liability insurance. This insurance limits the Company’s exposure and may enable it to recover a portion of any future amounts paid. Historically, the Company has not made any indemnification payments under such agreements and the Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to these obligations for any period presented.
