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.

ArmTypeDescription
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.

Frequently asked questions about CVL-865 High dose

What is CVL-865 High dose?

CVL-865 High dose refers to the higher-dose regimen of CVL-865, a small molecule being developed by AbbVie Inc. (ticker: ABBV). It is under study in psychiatry and neurology, specifically for panic disorder and seizures. The program remains in clinical development.

What is CVL-865 High dose used for?

CVL-865 High dose is being studied for panic disorder and seizures. One completed Phase 1 trial evaluated its effect on panic symptoms induced by carbon dioxide inhalation in healthy subjects, while a completed Phase 2 trial tested it as adjunctive therapy for focal onset seizures.

Who makes CVL-865 High dose?

CVL-865 High dose is developed by AbbVie Inc., which trades under the ticker ABBV. AbbVie is the sponsor of the clinical program evaluating this higher-dose regimen of CVL-865 in panic disorder and seizure indications.

What phase is CVL-865 High dose in?

CVL-865 High dose is in Phase 1 development. It is investigational and has not been approved by the FDA. The program includes one completed Phase 1 trial in panic disorder and one completed Phase 2 trial in focal onset seizures.

What clinical trials is CVL-865 High dose in?

CVL-865 High dose has been evaluated in two completed trials: NCT04592536, a Phase 1 study of its effect on carbon dioxide-induced panic symptoms in healthy subjects, and NCT04244175, a Phase 2 trial of adjunctive therapy for focal onset seizures that enrolled 154 participants across multiple countries.

Is CVL-865 High dose the same as CVL-865?

Yes, CVL-865 High dose is the higher-dose regimen of CVL-865. The two names refer to the same investigational small molecule developed by AbbVie Inc. (ABBV), studied in panic disorder and seizures.
