New shot before angioplasty may shield heart attack patients
NCT ID NCT06683131
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether starting the drug tafolecimab (a PCSK9 inhibitor) just before emergency angioplasty can lower the chance of major heart problems over the next year in people having a heart attack. About 1,160 adults will either get the drug plus standard care or standard care alone. The drug is given as a shot before the procedure and then every two weeks for a year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tafolecimab (a PCSK9 inhibitor drug given by injection)
- What this could lead to
- If it works, this could provide a new treatment option to reduce the risk of future heart problems after a heart attack.
- What could go wrong
- This is a Phase 4 trial, so the drug is already approved for other uses, but its benefit in this specific setting is unproven. Side effects from injections or the drug itself are possible.

Inclusion Criteria: * Adults 18-75 years old * AMI diagnosed according to the latest guidelines, including ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) * The requirement for STEMI was that primary PCI was scheduled within 12 hours of onset. * The requirement for NSTEMI was that coronary angiography was scheduled within 2 hours for very high-risk participants and within 24 hours for high-risk participants . * Regardless of baseline LDL-C levels * Participants voluntarily took part in this study and signed informed consent Exclusion Criteria: * Previous or ongoing treatment for any PCSK9i * Allergy to PCSK9i, statins, or any of the drug ingredients used during the trial * History of hemorrhagic cerebrovascular disease * History of old myocardial infarction/chronic heart failure * History of PCI or coronary artery bypass grafting (CABG) or preparation for CABG * Above Killip level II * Prolonged cardiopulmonary resuscitation (\>20min) * Definite mechanical complications (including perforation of the interventricular septum, or rupture of the papillary tendon bundle or the left ventricular free wall) * malignant arrhythmia * Severe uncontrolled infection, bleeding disorder, end-stage renal disease, severe liver disease, endocrine dysfunction, or the expected less than 1 year survival of malignant tumors * Pregnant or lactating women * Participate in other clinical trials
