Low Dose ColchicinE in pAtients With Peripheral Artery DiseasE to Address Residual Vascular Risk: A Randomized Trial
The Low dose ColchicinE in pAtients with peripheral Artery DiseasE to address residual vascular Risk (LEADER-PAD) trial will evaluate if anti-inflammatory therapy with colchicine will reduce vascular events in patients with symptomatic peripheral artery disease.
Inclusion: Age > 18 years; Symptomatic atherosclerotic LE PAD fulfilling at least one of the following:; Intermittent claudication with ankle/arm blood pressure ratio* (ABI ≤ 0.90) or artery stenosis ≥ 50% plus one of i. >1 vascular bed affected by atherosclerosis ii. Diabetes iii. Heart failure iv. Chronic kidney disease (eGFR < 60 mL/min/1.73 m2); Rest pain (mostly in foot) OR necrosis of limb OR gangrene of limb (corresponding to either Fontaine stages 3 or 4 OR Rutherford Classification categories 4 to 6). All must have an ankle/arm blood pressure ratio* (ABI ≤ 0.90) OR artery stenosis ≥ 50%; In cases of incompressible ankle arteries, the presence of toe pressure ≤ 60 mm Hg or toe-brachial index ≤ 0.70 is acceptable; Revascularization defined as limb bypass surgery or endovascular revascularization procedures (irrespective of the specific device used), including percutaneous transluminal angioplasty/stent of iliac or infra-inguinal arteries or extra-anatomical bypass surgery; Leg or foot amputation for arterial vascular indications; Written or verbal informed consent from the patient.
Exclusion: Cirrhosis or severe chronic liver disease; Current or planned long term use of cyclosporine, verapamil, HIV protease inhibitors, azole antifungals, or macrolide antibiotics (with the exception of azithromycin); eGFR < 30 mL/min/1.73 m2; Contraindication to colchicine; Long term requirement for colchicine for another clinical indication; Active diarrhoea; Woman who is pregnant, or breast-feeding or of child-bearing potential not protected by reliable contraception or is planning conception during the study; Patients who are deemed unlikely to return for follow-up; Patients with life expectancy < 1 year.
