Efficacy of Colchicine to Prevent Skin Relapses in Adult's IgA Vasculitis (COLCHIVAS)

November 4, 2026 updated by: Assistance Publique - Hôpitaux de Paris

Evaluation of Efficacy of Colchicine to Prevent Skin Relapses in Adult's IgA Vasculitis

Immunoglobulin A vasculitis (IgA-V), formerly called Henoch-Schönlein purpura, is an immune vasculitis. Relapses are frequent (30%) and most of the time cutaneous (90%). Cutaneous involvement in adults is more severe (haemorrhagic blister or necrotic skin lesions) and more extensive than in children. Quality of life can be significantly altered by frequent cutaneous relapses. Colchicine, historically used for gout flares, is known to be an " old " low cost drug inducing very few adverse events. This molecule inhibits polymorphonuclear cell-chemotaxis to the site of inflammation explaining colchicine clinical efficacy in diseases such as Familial Mediterranean Fever or Behçet disease. Efficacy of colchicine has also been reported in cutaneous leukocytoclastic vasculitis including IgA-V, but without clinical studies supporting this attitude.

Detailed Description

Immunoglobulin A vasculitis (IgA-V), formerly called Henoch-Schönlein purpura, is an immune vasculitis. Relapses are frequent (30%) and most of the time cutaneous (90%). Cutaneous involvement in adults is more severe (haemorrhagic blister or necrotic skin lesions) and more extensive than in children. Quality of life can be significantly altered by frequent cutaneous relapses. Colchicine, historically used for gout flares, is known to be an " old " low cost drug inducing very few adverse events. It inhibits polymorphonuclear cell-chemotaxis to the site of inflammation explaining colchicine clinical efficacy in diseases such as Familial Mediterranean Fever or Behçet disease. Efficacy of colchicine has also been reported in cutaneous leukocytoclastic vasculitis including IgA-V, but without clinical studies supporting this attitude To assess efficacy of colchicine in adult's cutaneous IgA-V, the investigators conduct a prospective, controlled, double blind, randomized clinical trial, national, multicenter and multidisciplinary (internal medicine, nephrology and dermatology): colchicine 1mg/day versus placebo for 6 months, with a 12 months total follow-up. The primary objective is to evaluate efficacy of colchicine versus placebo to prevent cutaneous relapses, 6 months after inclusion, in adult patients with cutaneous IgA vasculitis alone or associated with non-severe digestive or renal involvement.
