About this study

The RENATO trial is a multicenter randomized controlled trial that evaluates the efficacy of pioglitazone to improve renal outcomes in ANCA-associated vasculitis. Patients with biopsy-proven kidney involvement of ANCA vasculitis will be included in this trial at diagnosis. All patients will receive a standard of care immunosuppressive (SOC) therapy combining corticosteroids and rituximab (375 mg/m2/week for 4 consecutive weals followed by 500 mg re-infusion every 6 months). They will be randomized 1:1 to receive either pioglitazone 30 mg/day or placebo for 6 months, on top of SOC. The primary objective of this trial is to demonstrate that pioglitazone reduces kidney damage, reflected by the early improvement of proteinuria and serum creatinine levels. The secondary objectives will be to assess the efficacy of this drug on the reduction of hypertension and metabolic effects of glucocorticoids, to measure its impact on vasculitis activity and to evaluate the safety profile of pioglitazone in this population.
