Could KarXT be the key to treating teen schizophrenia?
NCT ID NCT07288567
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 10 times
Summary
This phase 3 trial is testing whether the drug KarXT can safely and effectively treat schizophrenia in adolescents aged 13 to 17. About 166 teens will receive either KarXT or a placebo, and researchers will track changes in symptoms like delusions and social withdrawal. The goal is to see if KarXT offers a new treatment option for this age group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KarXT (also known as BMS-986510)
- What this could lead to
- If it works, this could offer a new treatment option for teenagers with schizophrenia, potentially easing symptoms like hallucinations and social withdrawal.
- What could go wrong
- This is still a clinical trial, so it's not proven yet. The drug may not work better than a placebo, and side effects are possible. Results may not apply to all teens.
