One shot to ease anxiety? new drug RE104 enters human trial
NCT ID NCT07489651
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This Phase 2 trial tests whether a single injection of RE104 can reduce anxiety symptoms in 64 adults with generalized anxiety disorder, compared to a placebo. Participants receive one dose and are followed for four weeks to measure changes in anxiety severity using a standard rating scale. The study is currently recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RE104 for injection
- What this could lead to
- If it works, this could point toward a fast-acting, single-dose treatment option for generalized anxiety disorder.
- What could go wrong
- This is an early Phase 2 trial with only 64 people, so results may not apply broadly. The drug may not reduce anxiety better than placebo, and side effects are still being studied.
