Can a single shot stop clots? a new drug puts the idea to the test
NCT ID NCT03384966
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial investigates whether a single injection of selatogrel can quickly prevent platelets from clumping together in people with stable coronary artery disease. Researchers are also checking how fast the drug works, how long it lasts, and whether injecting it in the thigh or belly makes a difference. The study involves about 346 adults with stable coronary artery disease and compares selatogrel to a placebo.
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-use option for preventing heart attacks in people with stable coronary artery disease.
- What could go wrong
- This is a Phase 2 trial, so the drug is still being tested for safety and effectiveness. It may not work as hoped or could cause side effects like bleeding.

For women of childbearing potential: Negative urine pregnancy test at Visit 1 and at Visit 2 before randomization. 4. Stable Coronary artery disease (CAD) defined by the presence of any of the following conditions: 1. History of CAD with coronary artery stenosis on coronary angiogram ≥50%. 2. Previously documented myocardial infarction occurring more than 3 months prior to randomization. 5. Antiplatelet background therapy stable for at least 1 month prior to randomization. 6. Body weight ≥ 40.0 kg (88.2 lbs). Main Exclusion Criteria: 1. Acute coronary syndrome, percutaneous coronary intervention or any intervention for peripheral artery disease within 3 months prior to randomization. 2. Acute ischemic stroke or transient ischemic attack (TIA) within 3 months prior to randomization. 3. Active internal bleeding, or medical history of recent (\< 1 month) bleeding disorders or conditions associated with high risk of bleeding (e.g., clotting disturbances, gastrointestinal bleed, hemoptysis). 4. Hemoglobin ≤ 10 g/dL at screening. 5. Loss of at least 250 mL of blood within 3 months of screening. 6.
