First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times
Summary
This Phase 3 study tests whether a combination of two drugs, KarXT and KarX-EC, can safely reduce irritability in children and adolescents aged 5 to 17 with autism spectrum disorder. About 176 participants will receive either the drug combo or a placebo for 8 weeks. The main goal is to see if the treatment lowers scores on a standard irritability checklist.
