E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to evaluate the efficacy of BIIB074
in treating pain experienced by subjects with TN.
The primary objective of the LTE phase of the study is to evaluate the
long-term safety and tolerability of BIIB074 in subjects with TN. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives include the following:
- To investigate the safety and tolerability of BIIB074 in subjects with
TN.
- To evaluate the population PK of BIIB074. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- A diagnosis of TN for at least 3 months based on 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.
NOTE: Other protocol defined Inclusion criteria may apply |
|
E.4 | Principal exclusion criteria |
- 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.
NOTE: Other protocol defined Exclusion criteria may apply |

E.5 End points |
E.5.1 | Primary end point(s) |
1. Time from randomization to loss of therapeutic response (LOTR).
2. Change from baseline to Week 12 of the double-blind period in weekly
mean ADP.
3. Proportion of subjects with a response in number of paroxysms at
Week 12 of the double-blind period.
4. Proportion of subjects with a PGIC response at Week 12 of the doubleblind
period.
5. Change from baseline to Week 12 of the double-blind period in the
Penn Facial Pain Scale-Revised (PENN-FPS-R) score.
The primary endpoint of LTE phase is assessment of the following safety
parameters:
- Incidence of AEs and SAEs
- Laboratory safety tests
- Vital signs
- 12-lead ECG parameters C-SSRS |
