New heartburn drug candidate tested for heart safety in healthy volunteers
NCT ID NCT05469854
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 1 trial is testing a new drug called linaprazan glurate in 121 healthy adults to see how the body absorbs and processes it, and whether it affects heart rhythm. The study is double-blind and placebo-controlled, meaning some participants get a dummy pill. It is an early step to gather safety data before testing the drug in people with GERD (chronic acid reflux).
