Healthy volunteers help uncover best way to take cancer pill
NCT ID NCT05468164
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed Phase 1 study looked at how food and the heartburn drug omeprazole affect the absorption of selpercatinib, a cancer medication. Twenty healthy adults took selpercatinib under different conditions—with a high-fat meal, on an empty stomach, and after taking omeprazole. The goal was to see how fast the drug enters the bloodstream and how long it stays in the body, helping guide future dosing instructions.
