Can a quick shot stop a heart attack in its tracks?
NCT ID NCT03487445
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This phase 2 trial tests whether a single injection of selatogrel can rapidly prevent platelets from clumping together in adults having a heart attack. Participants receive either an 8 mg or 16 mg dose in the thigh, and researchers measure how quickly platelet activity drops. The goal is to see if this drug could provide a fast, easy way to reduce clot formation during a heart attack.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an injectable drug called selatogrel that prevents platelets from clumping together
- What this could lead to
- If it works, selatogrel could offer a fast-acting, easy-to-give treatment for heart attacks, potentially reducing damage to the heart.
- What could go wrong
- This is an early-phase trial with only 48 participants, so results may not apply to everyone. The drug may not work fast enough or could cause bleeding risks.
