A Phase 2 interventional study of Colchicine group (experimental arm) and Placebo group (control arm) in Myocardial Infarction, sponsored by Hospices Civils de Lyon. Completed at 8 sites in France. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-08-01.

Inflammatory processes have been identified as key mediators of ischemia/ reperfusion injury in ST-segment elevation myocardial infarction. They add additional damage to the myocardium and are associated with clinical adverse events (heart failure and cardiovascular death) and poor myocardial recovery. All the different anti-inflammatory approaches to reduce reperfusion injury have been disappointing.
Colchicine is a well-known substance with potent anti-inflammatory properties. In a recent pilot study performed in 151 acute STEMI patients treated with primary percutaneous coronary intervention(PPCI) Deftereos et al. showed a 50% reduction of infarct size (creatine kinase release) with a short course treatment of colchicine in comparison to placebo.
One mechanism to explain this effect could be the reduction of adverse left ventricular (LV) remodelling. LV remodelling is part of the healing process of myocardium after MI. It is defined as the end diastolic volume (EDV) increase in the first months after MI. Adverse LV remodelling is increased by inflammation and ultimately leads to heart failure.
Our main hypothesis is that colchicine with its anti-inflammatory properties significantly reduces the initiation of adverse LV remodelling, together with a significant reduction of infarct size and microvascular obstruction in comparison to placebo in acute STEMI patients referred for PPCI.
After inclusion and randomisation, patients will receive the first part of their experimental treatment: colchicine or placebo before PCI, then, the second part after PCI and during 5 days. They will be followed up during their hospitalization and until one year. In order to evaluate LV remodelling, two cardiac magnetic resonance studies will be performed during their participation: one during their hospitalization and a second at 3 months. At 1 year, adverse events will be collected by phone.
Exclusion Criteria:
The patients will receive an oral bolus of colchicine of 2 mg followed by 0.5 mg b.i.d. during 5 days.
Drug: Colchicine group (experimental arm)
The patients will receive an oral bolus of placebo of 2 mg followed by 0.5 mg b.i.d. during 5 days.
Drug: Placebo group (control arm)
In the experimental group, patients will receive colchicine, starting with a loading dose of 2 mg at the time of revascularization and continuing with 0.5 mg twice daily (b.i.d) for 5 days.
In the placebo group, patients will receive placebo, starting with a loading dose of 2 mg at the time of revascularization and continuing with 0.5 mg twice daily for 5 days.
