简要总结
The primary objective of the study is to evaluate the efficacy of BIIB074 in treating pain experienced by participants with trigeminal neuralgia (TN). Secondary objectives of this study are to investigate the safety and tolerability of BIIB074 in participants with TN and to evaluate the population pharmacokinetics (PK) of BIIB074.

入选标准
- •A diagnosis of trigeminal neuralgia (TN) for at least 3 months based on International Headache Society (IHS) diagnostic criteria.
- •Participant must have failed at least 1 prior standard of care pharmacologic treatment for TN (defined as an inadequate response or intolerance to treatment), as determined by the Investigator based on medical history.
- •Age ≥18 years at the time of informed consent.

- •Participants must have recorded their pain score in their eDiary on at least 5 days during the run-in period (Days -7 to -1).
排除标准
- •History or positive test result at Screening for hepatitis C virus antibody or current hepatitis B infection (defined as positive for hepatitis B surface antigen [HBsAg] and/or hepatitis B core antibody [HBcAb]).
- •Positive history of human immunodeficiency virus (HIV) or a positive HIV test at Screening.
- •Participants with facial pain other than TN.
- •Personal or family (first-degree relative) history of seizures (except for simple febrile convulsions) or clinically significant head injury.
- •Known hypersensitivity to BIIB074 or components of the BIIB074 formulation or matching placebo.
- •Positive pregnancy test result at Screening (women of childbearing potential only)
- •Has donated blood or blood products within a 30-day period prior to Screening.
- •NOTE: Other protocol defined Inclusion/Exclusion criteria may apply

结局指标
主要结局
Percentage of Participants Classified as Responders at Week 12 of the Double-Blind Period
时间窗: Week 12
A participant who meets all of the following criteria will be classified as a responder: (1)Has a reduction of \>=30% in mean pain score compared with baseline (2)Has not discontinued randomized treatment before the end of Week 12 of the double-blind period (3)Has not taken prohibited pain medication before the end of Week 12 of the double-blind period.
Number of Participants Experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs) During the Long Term Extension (LTE) Period
时间窗: Baseline up to Week 52
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE was defined as any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event; however, this does not include an event that, had it occurred in a more severe form, might have caused death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect.
