New pill could ease the 'Suicide Disease' for patients failed by current meds
NCT ID NCT05217628
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a daily drug called basimglurant for adults with trigeminal neuralgia, a condition causing severe facial pain often called the 'suicide disease.' The trial includes 166 people who still have pain despite current treatments. After an 8-week run-in on the drug, participants are randomly assigned to continue basimglurant or switch to placebo for 12 weeks to see if the drug maintains pain relief.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Basimglurant (also called NOE-101), a daily oral drug
- What this could lead to
- If it works, this could provide a new pain relief option for people with trigeminal neuralgia who don't get enough help from current treatments.
- What could go wrong
- This is an early-to-mid stage trial with only 166 people. The drug may not prove better than placebo, and side effects are still being studied.
