Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with a confirmed diagnosis of primary trigeminal neuralgia experiencing significant daily pain.

Probably not a fit

Patients with major psychiatric diagnoses unrelated to trigeminal neuralgia may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy and safety of basimglurant (NOE-101), a potent inhibitor of the metabotropic glutamate receptor 5 (mGluR5), in adults suffering from trigeminal neuralgia (TN). Participants will receive either the drug or a placebo, and their pain levels will be monitored using a patient pain diary and the Patient-reported Global Impression of Change (PGI-C). The goal is to determine if basimglurant can effectively reduce the duration and intensity of facial pain associated with TN compared to baseline measurements.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate the debilitating pain experienced by patients with trigeminal neuralgia.

How similar studies have gone: While the approach of targeting mGluR5 for pain relief is promising, the specific efficacy of basimglurant in trigeminal neuralgia is still being evaluated and has not been widely tested in prior studies.
