New drug candidate aims to calm restless legs when current meds backfire
NCT ID NCT03218969
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small study tested whether ecopipam, a drug that blocks a specific brain receptor, can help people with restless leg syndrome whose symptoms have gotten worse from their usual dopamine-based medication. Ten adults took either ecopipam or a placebo for six weeks, then switched after a two-week break. Researchers measured changes in symptom severity and how much of the body was affected.

What this could lead to
If it works, this could offer a new way to manage RLS when standard treatments stop working or make symptoms worse.
