First seen Jun 24, 2026 · Last updated Aug 11, 2026 · Updated 3 times
Summary
This study tests an experimental drug called RAP-219 for people with bipolar I disorder who are currently experiencing a manic episode. About 250 participants will receive either RAP-219 or a placebo daily for 21 days. Researchers will measure changes in manic symptoms using a standard rating scale to see if the drug is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RAP-219 (oral tablet)
- What this could lead to
- If it works, this could provide a new short-term treatment option to quickly reduce manic symptoms in people with bipolar I disorder.
- What could go wrong
- This is an early Phase 2 trial with only 250 participants, so results may not apply to everyone. The drug may prove no better than placebo, and side effects are still being studied.
