NCT ID NCT07044401
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how giving a single shot of the experimental drug KAI-9531 in different places (upper arm, thigh, or belly) changes the amount of drug that gets into the blood. It involved 51 healthy volunteers with a range of body sizes. The goal was to find the best injection spot for future studies.
