Inclusion Criteria
  1. Male and Female participants 18 to 75 years of age at time of consent.

  2. Diagnosis of Focal Onset Epilepsy at least 1 year prior to screening visit defined by 2017 International League Against Epilepsy (ILAE) Classification and based on requirements of Epilepsy Adjudication criteria.

    a. Focal seizures i. Focal aware seizures with clinically observable signs and/or symptoms ii. Focal impaired awareness seizures with clinically observable signs and/or symptoms iii. Focal to bilateral tonic-clonic seizures

  3. Subject meets the 2009 ILAE definition of drug resistant epilepsy, failure of adequate trials of two tolerated and appropriately chosen and used anti-seizure medication (ASM) schedules (whether as monotherapies or in combination) to achieve sustained seizure freedom.

  4. Ability to keep accurate seizure diaries

  5. Current treatment with at least 1 and up to 3 ASMs and 4 epilepsy treatments in total

Key

Exclusion Criteria
  1. History of status epilepticus (convulsive status epilepticus for > 5 minutes or focal status epilepticus with impaired consciousness for > 10 minutes) within the last 6 months prior to screening visit that is not consistent with the subject's habitual seizure.
  2. History of repetitive/cluster seizures (where individual seizures cannot be counted) within the last 6 months prior to screening visit and during observation phase.
  3. Resection neurosurgery for seizures <4 months prior to the screening visit.
  4. Radiosurgery performed <2 years prior to the screening visit.
  5. Subjects with only focal aware nonmotor seizures which involve subjective sensory or psychic phenomena only, without impairment of consciousness or awareness (formally called simple partial seizures), with or without ictal EEG correlation with clinical symptoms.
  6. Any condition that would interfere with the subject's ability to comply with study instructions, place the subject at unacceptable risk, and/or confound the interpretation of safety or efficacy data from the study, as judged by the Investigator

Primary Outcome Measures
NameTimeMethod
Change from Baseline in 28-day average seizure frequencyBaseline, 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.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants with at at least 50% reduction in seizure frequency per monthBaseline, Week 8 to Week 16

To compare the efficacy of 2 dose strengths of BHV-7000 to placebo as adjunctive therapy for refractory focal onset epilepsy as measured by the proportion of subjects that have at least a 50% reduction in seizures per month (28 days). This objective will be measured by comparing the proportion of subjects with at least a 50% reduction in 28-day average seizure frequency over the course of the 8 week double-blind phase to the observation phase.

Change from Baseline in 28-day average seizure frequency during first month of treatmentBaseline, Week 8 to Week 12

To compare the efficacy of BHV-7000 to placebo during the first month of treatment. This objective will be measured by the change in log-transformed 28-day adjusted seizure frequency from observation phase over the first month of the double blind phase.

Percentage of Participants with at at least 75% reduction in seizure frequency per monthBaseline, Week 8 to Week 16

To compare the efficacy of BHV-7000 to placebo as measured by the proportion of subjects that have at least a 75% reduction in seizures per month (28 days). This objective will be measured by comparing the proportion of subjects with at least a 75% reduction in 28-day average seizure frequency over the course of the double-blind phase compared to the observation phase.

Percentage of Participants with seizure freedom during DB PhaseWeek 8 to Week 16

To compare the efficacy of BHV-7000 to placebo on seizure freedom (100% seizure reduction during the DBP phase). This objective will be measured by proportion of subjects that are seizure free during the double-blind phase.

Change from baseline in 7-day adjusted seizure frequency during first week of treatmentBaseline, Week 8 to Week 9

To compare the efficacy of BHV-7000 to placebo during the first week of treatment. This objective will be measured by the change in log-transformed 7-day adjusted seziure frequency from observation phase over the first week of the double-blind phase.

Change from baseline in Patient Global Impression of Change (PGI-C)Baseline, Week 16

To compare the efficacy of BHV-7000 to placebo on the patient global impression of change (PGI-C). This objective will be measured by proportion of subjects at week 8 of double-blind treatment phase with a PGI-C response of "minimally improved", "much improved" or "very much improved". This scale is a 7-point Likert scale with response options of:

(1) "very much improved" , (2) "much improved", (3) "minimally improved", (4) "no change", (5) "minimally worse", (6) "much worse", (7) and "very much worse"

Number of Participants With Deaths, Serious AEs (SAEs), AEs Leading to Study Drug Discontinuation, and moderate or severe AEsWeek 8 to Week 16

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 Participants With Clinically Significant Laboratory AbnormalitiesWeek 8 to Week 16

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.
