LEADER-PAD - Clinical Trial

¿Cuál es el Propósito de este estudio?

We are doing this study to find out if a small dose (0.5 mg) of a drug called colchicine (the study drug) is beneficial for people with peripheral artery disease (PAD). We want to know if it has the potential to lower the risk of heart attack, stroke, and corrective leg surgeries for people who have PAD. The study drug is FDA-approved for the treatment of some inflammatory conditions (e.g., gout), but it is not approved for the treatment of PAD.
