Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the efficacy of BHV3000 compared to placebo for subjects with treatment refractory Trigeminal Neuralgia as measured by a 2-point or greater reduction in the average Numeric Pain Rating Scale between the two-week treatment phases.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Subjects with a clinical diagnosis of typical or atypical classical trigeminal neuralgia based on the International Classification of Headache Disorders, 3rd edition, beta version.
2. Trigeminal neuralgia symptoms for a minimum of 8 weeks prior to randomization visit.
3. Neuroimaging to exclude another cause for the neuralgia, other than neurovascular compression.

Exclusion Criteria

1. Subject has a structural lesion on neuroimaging, other than vascular compression of the trigeminal nerve or nerve root that would explain the neuralgia
2. Subject has a clinically evident neurologic deficit on neurologic exam of the cranial nerves
3. Subjects with a history of HIV disease
4. Subject history with current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischemic heart disease, coronary artery vasospasm, and cerebral ischemia. Subjects with Myocardial Infarction (MI), Acute Coronary Syndrome (ACS), Percutaneous Coronary Intervention (PCI), cardiac surgery, stroke or transient ischemic attack (TIA) during the 6 months prior to screening
5. Uncontrolled hypertension (high blood pressure) at screening
6. Subject has a current diagnosis of major depression, other pain syndromes, psychiatric conditions (e.g., schizophrenia), dementia, or significant neurological disorders (other than migraine) that, in the Investigator's opinion, might interfere with study assessments
7. Subject has a history of gastric, or small intestinal surgery (including Gastric Bypass, Gastric Banding, Gastric Sleeve, Gastric Balloon, etc.), or has a disease that causes malabsorption
8. Subject has a history or diagnosis of Gilbert's Syndrome or any other active hepatic or biliary disorder
9. The subject has a history or current evidence of any significant and/or unstable medical conditions (e.g., history of congenital heart disease or arrhythmia, known suspected infection, hepatitis B or C, or cancer) that, in the investigator's opinion, would expose them to undue risk of a significant adverse event (AE) or interfere with assessments of safety or efficacy during the course of the trial
10. History of, treatment for, or evidence of, alcohol or drug abuse within the past 12 months or subjects who have met DSM-V criteria for any significant substance use disorder within the past 12 months from the date of the screening visit
11. Hematologic or solid malignancy diagnosis within 5 years prior to screening. Subjects with a history of localized basal cell or squamous cell skin cancer are eligible for the study if they are cancer-free prior to the screening visit in this study.
12. Hematologic or solid malignancy diagnosis within 5 years prior to screening. Subjects with a history of localized basal cell or squamous cell skin cancer are eligible for the study if they are cancer-free prior to the screening visit in this study.
13. Body mass index \>33kg/m²
14. History of gallstones or cholecystectomy
