Study Endpoints

Primary Endpoints

Response Ratio (RRatio)
Baseline Period; Maintenance Phase Days 15 through 71

Response Ratio (RRatio) is calculated as RRatio=(T-B)/(T+B) ×100, where T represents the focal onset seizure frequency rate per week in the Maintenance Phase and B represents the focal onset seizure frequency rate per week in the Baseline Period. The Response Ratio ranges between -100 and 100; negative values indicate reduction in seizure rate and positive values indicate increase in seizure rate during treatment.

Secondary Endpoints

PlaceboPLACEBO_COMPARATORParticipants received a placebo matched to CVL-865 tablets orally twice a day (BID) during the 2-week Titration Phase, the 8-week Maintenance Phase, and the 3-week Taper Phase.
CVL-865 7.5 mg BIDEXPERIMENTALCVL-865 tablets were administered orally as 2.5 mg twice a day (BID) for 1 week followed by 5 mg BID for another week during the Titration Phase, and then 7.5 mg BID during the 8-week Maintenance Phase. For participants not enrolling into the open-label extension trial, following the Maintenance Phase the dose was gradually decreased over a 3-week Taper Phase.
CVL-865 25 mg BIDEXPERIMENTALCVL-865 tablets were administered orally as 5 mg twice a day (BID) for 1 week followed by 12.5 mg for another week during the Titration Phase, and then 25 mg BID during the 8-week Maintenance Phase. For participants not enrolling into the open-label extension trial, following the Maintenance Phase the dose was gradually decreased over a 3-week Taper Phase.
