Summary

This early-stage study tests a single dose of ABBV-547 in healthy adults to check its safety, how the body processes it, and any side effects. About 121 participants in the US and Japan will receive either the drug or a placebo. The study has two parts with different dosing groups.

What this could mean

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

Active substance
ABBV-547
What could go wrong
This is a very early Phase 1 trial in healthy volunteers, so it cannot show whether ABBV-547 works for any disease. The main goal is safety, not effectiveness.
