Can a new drug cool down inflamed arteries and prevent heart attacks?
NCT ID NCT06263244
First seen Jun 24, 2026 · Last updated Aug 07, 2026 · Updated 4 times
Summary
This phase 3 trial tests whether ziltivekimab, a drug that targets inflammation, can reduce swelling in the arteries of 40 people with coronary artery disease. Participants receive either the drug or a placebo, and researchers use advanced imaging and blood tests to measure changes. The goal is to see if this approach can lower inflammation, which is linked to heart attacks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ziltivekimab (a monoclonal antibody targeting IL-6)
- What this could lead to
- If it works, this could point toward a treatment that lowers inflammation in arteries, potentially reducing heart attack risk.
- What could go wrong
- This is a small, early-phase trial focused on imaging and lab markers, not clinical outcomes like heart attacks. The drug may not show clear benefits or could have side effects like infections.
