Item 8.01. Other Events.
On June 1, 2026, Praxis Precision Medicines, Inc. (the “Company”) announced results from the Phase 2/3 POWER1 study evaluating vormatrigine in patients with focal onset seizures (“FOS”). The POWER1 study in highly refractory patients with FOS did not meet its primary success measure. The secondary measure, the 50% response rate, was met and seizure reduction during the second half of the study on higher dose (30 mg) was more pronounced. Vormatrigine was generally well-tolerated and adverse event-related discontinuations were less than 10%. Approximately 90% of patients from the vormatrigine arm transitioned to and remain in the open label extension study.
The Company is pausing enrollment in the POWER2 study to reassess the vormatrigine program and determine potential modifications.
