Collaboration Revenue | 9. Collaboration revenue: In December 2019, the Company entered into a license and collaboration agreement with Neurocrine Biosciences, Inc. to develop treatments for epilepsy, as described in the Company’s 2025 Annual Report on Form 10-K. The agreement also included a multi-year research collaboration to discover, identify and develop additional novel Nav1.6 and dual Nav1.2/1.6 inhibitors, which was completed in June 2022. As part of this ongoing collaboration, in February 2025, NBI-921355 progressed into a Phase 1 first-in-human study as a potential treatment for certain types of epilepsy and a $7,500 milestone was recognized in the six months ended June 30, 2025. Consideration associated with performance milestones is recognized as revenue using the most likely amount method when it is probable that a significant reversal of the cumulative revenue recognized will not occur.
