Using low dose colchicine to reduce vascular risks in patients with peripheral artery disease.
Official title: 2/2 Low dose colchicine in pAtients with peripheral artery DiseasE to assess residual vascular risk (LEADER-PAD)
Funded at Duke University · NIH-10982434 · Data updated 2026-11-12
This study is looking at whether a low dose of colchicine can help people with peripheral artery disease (PAD) by reducing the risk of serious heart and leg problems, and we're inviting 1,000 participants from the U.S. to join in and see how it works compared to a placebo.

Who could benefit from this research
✓Could help
Ideal candidates for this research are individuals diagnosed with peripheral artery disease who are at risk for cardiovascular complications.
✕Less likely to help
Patients without a diagnosis of peripheral artery disease or those who are not at risk for cardiovascular events may not benefit from this research.
What this research studies
This research investigates the effects of low dose colchicine on patients with peripheral artery disease (PAD) through a randomized, double-blind, placebo-controlled trial. The study aims to enroll 1,000 participants from the U.S. as part of a larger multinational effort involving 6,150 participants. By targeting inflammation with colchicine, the research seeks to determine if this treatment can lower the risk of serious cardiovascular and limb-related complications. Participants will be monitored closely to assess the outcomes of the treatment compared to a placebo.
Why it matters
Potential benefit: If successful, this research could significantly reduce the risk of cardiovascular events and improve the quality of life for patients with peripheral artery disease.
How similar studies have gone: Previous studies have shown that colchicine can reduce cardiovascular risks in patients with coronary disease, indicating potential for success in this novel application.
