Study Endpoints
Primary Endpoints
Number of Participants With Deaths, Serious AEs (SAEs), AEs Leading to Study Drug Discontinuation, and moderate or severe AEs
Up to 104 weeks

To assess the safety and tolerability of BHV-7000. This objective will be measured by assessing the number of unique subjects with deaths, SAEs, AEs leading to discontinuation, and moderate and severe AEs.

Number of Subjects with Clinically Significant Laboratory Abnormalities
Up to 104 weeks

To assess the safety and tolerability of BHV-7000. This objective will be measured by assessing the number of unique subjects with grade 3 or 4 laboratory abnormalities.

Change from Baseline in 28-day average seizure frequency
Baseline, Week 8 to Week 16

To compare the efficacy of each of 2 doses of BHV-7000 to placebo as an adjunctive therapy for refractory focal onset epilepsy as measured by the change from OP (observational phase) in 28-day average seizure frequency. The primary objective will be measured by comparing the observation phase (8 weeks) to the 8-week double-blind treatment phase.

Part B: Change from Baseline in 28-day average seizure frequency
Baseline, Week 8 to Week 20 of Part B

To compare the efficacy of each of 2 doses of BHV-7000 to placebo as an adjunctive therapy for refractory focal onset epilepsy as measured by the change from OP (observational phase) in 28-day average seizure frequency. The primary objective will be measured by comparing the observation phase (8 weeks) to the 12-week double-blind treatment phase.

Part A: Number of Participants With Deaths, Serious AEs (SAEs), AEs Leading to Study Drug Discontinuation, and moderate or severe AEs
Week 8 to Week 20 of Part A

To assess the safety and tolerability of BHV-7000. This objective will be measured by assessing the number of unique subjects with deaths, SAEs, AEs leading to discontinuation, and moderate and severe AEs.

Part A: Number of Participants With Clinically Significant Laboratory Abnormalities
Week 8 to Week 20 of Part A

To assess the safety and tolerability of BHV-7000. This objective will be measured by assessing the number of unique subjects with grade 3 and 4 laboratory abnormalities.

Secondary Endpoints
Percentage of Participants with at at least 50% reduction in seizure frequency per month
Baseline, Week 8 to Week 16
Change from Baseline in 28-day average seizure frequency during first month of treatment
Baseline, Week 8 to Week 12
Percentage of Participants with at at least 75% reduction in seizure frequency per month
Baseline, Week 8 to Week 16
