Summary

This phase 2 trial tests whether meplazumab, an antibody given by IV, can reduce inflammation and fatty buildup in the arteries of people with coronary artery disease. The study involves 18 participants and will compare three different doses to a placebo. It is an early, exploratory study focused on safety and finding the right dose.

What this could mean

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

Active substance: Meplazumab (a lab-made antibody given by IV infusion)
What this could lead to: If it works, this could point toward a new way to reduce artery inflammation and slow plaque buildup in people with coronary artery disease.
What could go wrong: This is a very small, early-phase trial with only 18 participants, so results may not apply widely. The drug's long-term safety and effectiveness are still unknown.
