NCT05217628

Brief Summary

Trigeminal neuralgia (TN), also called "tic douloureux", is the most common form of craniofacial neuropathic pain and is considered the cause of one of the most painful afflictions known in medical practice. This study is designed to evaluate the efficacy and safety of 1.5mg - 3.5mg basimglurant in adults with TN.

Study Arms (2)

Arm A: Basimglurant/NOE-101

EXPERIMENTAL

* Period 1 (Run-in: Baseline1 to Week 8): Basimglurant once daily dosing starting dose 1.5mg * Period 2 (Double blind: Weeks 9 to 20): Participants will receive double-blind treatment with Basimglurant once daily. * Open-label Extension (OLE): On completion of Period 2, participants will be offered open label treatment with Basimglurant in an open label extension for up to 52 weeks.

Drug: Basimglurant

Arm B: Placebo

PLACEBO COMPARATOR

\- Period 2 (Double blind: Week 9 to Week 20): Participant randomized to placebo will receive the corresponding number of matching placebo capsules.

Other: Placebo

Interventions

Period 1: Basimglurant 1.5 to 3.5 mg QD titrated on individual tolerability. Period 2: Patients randomized to receive either double blind Basimglurant at the tolerated dose from Period 1 or Placebo. OLE: Open label Basimglurant at the dose tolerated from Period 2, patients previously assigned placebo in period to be titrated to the Period 1.

Also known as: NOE-101
