Because patients with stable coronary artery disease are at continued risk of major atherosclerotic events despite effective secondary prevention strategies, there is a need to continue to develop additional safe, effective and well-tolerated therapies for secondary prevention of cardiovascular disease. RATIONALE AND DESIGN: The LoDoCo (Low Dose Colchicine) pilot trial showed that the anti-inflammatory drug colchicine 0.5 mg once daily appears safe and effective for secondary prevention of cardiovascular disease. Colchicine's low cost and long-term safety suggest that if its efficacy can be confirmed in a rigorous trial, repurposing it for secondary prevention of cardiovascular disease would have the potential to impact the global burden of cardiovascular disease. LoDoCo2 is an investigator-initiated, international, multicentre, double-blind, event driven trial in which 5522 patients with stable coronary artery disease tolerant to colchicine during a 30-day run-in phase have been randomized to colchicine 0.5 mg daily or matching placebo on a background of optimal medical therapy. The study will have 90% power to detect a 30% reduction in the composite primary endpoint: cardiovascular death, myocardial infarction, ischemic stroke and ischemia-driven coronary revascularization. Adverse events potentially related to the use of colchicine will also be collected, including late gastrointestinal intolerance, neuropathy, myopathy, myositis, and neutropenia. ConclusionThe LoDoCo2 Trial will provide information on the efficacy and safety of low-dose colchicine for secondary prevention in patients with stable coronary artery disease.Copyright © 2019 Elsevier Inc.
