Colchicine in Percutaneous Coronary Intervention
Trial Summarized By: Mohammad-Ali Jazayeri, MD | Reviewed/Approved by: James de Lemos, MD
Anti-inflammatory Therapy During Percutaneous Coronary Intervention
The goal of the Colchicine-PCI trial was to study whether colchicine administration prior to percutaneous coronary intervention (PCI) reduces PCI-related myocardial injury, as compared to placebo, in patients referred for coronary angiography with possible PCI.
Pre-PCI colchicine reduced post PCI inflammation but not the risk of PCI-related myocardial injury.
Results: Colchicine PCI with Binita Shah
Principal investigator Binita Shah, MD, MS explains the results from Cochicine-PCI. Dr. Shah is an interventional cardiologist at NYU Langone Health.
Purpose: To evaluate whether pre-procedure colchicine would reduce PCI-related myocardial injury.
Trial Design: Phase 4 trial N=714. Double blinded. Follow-up 6 years. Randomized to pre-procedure colchicine 1.8 mg PO over 1 hour versus placebo.
Primary Endpoints: PCI-related myocardial injury
Results: Pre-PCI colchicine compared to placebo reduced post-PCI inflammation biomarkers but not PCI-related myocardial injury or MACE at 30 days.
|PCI-related myocardial injury||118 patients
|MACE at 30 days||23 patients
Primary Endpoints Results
- Myocardial injury (400 subjects): Peri-procedural myocardial injury using troponin I, as defined by the Universal Definition of myocardial infarction
- Colchicine 118 (57.3%) vs. placebo 122 (64.2%); P=.19
Secondary Endpoints Results
- Peri-procedural myocardial injury using CKMB & the SCAI definition of clinically relevant myocardial infarction (MI) after coronary revascularization
- Colchicine 6 (2.9%) vs. placebo 9 (4.7%); P=.49
- Occurrence of major adverse cardiac events (MACE) with composite of the earliest occurrence of death from any cause, non-fatal MI (defined by the Universal Definition), or target vessel revascularization (bypass surgery or repeat PCI of the target vessel) at 30 days: Colchicine 23 (11.2%) vs. placebo 25 (12.9%); P=.71
- Type 4a MI (Universal): 23 (11.2%) vs. 23 (12.1%); P=.89
- Type I MI (Universal): 0 vs. 1 (0.5%); P=.49
- Target vessel revascularization: 0 vs. 0
- All-cause mortality: 0 vs. 1 (0.5%); P=.49
Inflammatory Biomarker Sub-study
- Primary Outcome (280 subjects):
- There was no significant difference in the change in soluble IL-6 levels, from baseline to 1 hour post-PCI, when comparing colchicine (n=141) and placebo (n=139) groups.
- Other Key Findings:
- IL-6 changes at 24 hrs post-PCI: increased less 24 hours post-PCI in the colchicine vs. placebo groups (76% [-6, 898] vs. 338% [27, 1264]; p=0.02)
- High sensitivity C-reactive protein (hsCRP) concentration increased less 24 hours after PCI in the colchicine vs. placebo groups (7% [-13, 70] vs. 57% [0, 145]; p=0.001)
Key Findings: Among 400 subjects who underwent PCI, there was no significant difference in the probability of PCI-related myocardial injury between the colchicine (n=206) and placebo (n=194) groups (57.3% vs. 64.2%; P=.19). There was also no significant difference in inflammatory biomarker changes within 1 hour post-PCI, though at 24 hours post-PCI, two inflammatory markers, IL-6 (76% vs. 338%; P=.02) and hsCRP (7% vs. 57%; p=.001), had increased less in the colchicine group compared to placebo.
Impression: While colchicine appears to attenuate increases in inflammatory biomarkers over the first 24 hours after PCI, there was no significant difference in peri-procedural myocardial injury or major adverse cardiovascular events at 30 days post-PCI.

Trial Design — Randomized, double blind, placebo-controlled, single-site trial with parallel assignment to either colchicine (1.2 mg prior to PCI and 0.6 mg within 1 hr post-PCI) or placebo of the same dose
Trial Population: — 714 were enrolled, 400 adult (>18 yrs) patients undergoing PCI were studied; 280 were part of a pre-specified inflammatory marker sub-study
- Key Inclusion Criteria:
- Adult men & women >18 years of age
- Referred for coronary angiography with possible PCI
- Key exclusion criteria:
- Colchicine use within 1 month
- History of colchicine intolerance
- Glomerular filtration rate <30 mL/min or on dialysis (due to need for adjusted dosing
- Active malignancy or infection
