New schizophrenia drug KarXT checked for risky drug interactions

NCT ID NCT07118215

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage study is testing whether KarXT, a new drug for schizophrenia, changes how the body processes three other common medications (midazolam, fexofenadine, and digoxin). Sixty healthy adults will take KarXT along with each of these drugs to see if their levels in the blood are affected. The goal is to identify any potential drug interactions before KarXT is used more widely.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

KarXT (a combination of xanomeline and trospium chloride)

What this could lead to

If successful, this study will show whether KarXT can be safely taken with other common medications without changing their effects.

What could go wrong

This is an early phase 1 study in only 60 healthy volunteers, not patients. It only measures drug levels, not real-world safety or effectiveness.
