New fibromyalgia drug AXS-14 enters final testing phase
NCT ID NCT07398417
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This Phase 3 study tests whether AXS-14 (esreboxetine) can help manage fibromyalgia symptoms like pain and fatigue. About 620 adults with fibromyalgia will take the drug or a placebo daily. The study uses a 'randomized withdrawal' design to see how long the drug's effects last.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AXS-14 (esreboxetine) tablets taken once daily
- What this could lead to
- If successful, AXS-14 could offer a new daily medication option to help manage fibromyalgia pain and other symptoms.
- What could go wrong
- This is a Phase 3 trial, but it's a withdrawal study—meaning it tests if stopping the drug leads to symptom return. It may not work for everyone, and side effects are possible.
