Phase phase 4
Sponsor Hospices Civils de Lyon
Start date July 1996
Trial size 124 participants
Trial identifier NCT00400075, 95.067/2


To assess the efficacy of systemic corticosteroids alone as first-line treatment of polyarteritis nodosa and microscopic polyangiitis without poor-prognosis factors as defined by the five-factor score (FFS=0), and to compare the efficacy and safety of azathioprine vs pulse cyclophosphamide as adjunctive immunosuppressive therapy to treat failure or relapse.

Additional Information

Official title CHUSPAN PAN BP Treatment of Polyarteritis Nodosa and Microscopic Polyangiitis Without Poor-Prognosis Factors a Prospective Randomized Study in 125 Patients
Principal investigator Jean-François Cordier, MD
Description All patients initially treated with systemic corticosteroids alone: optional IV methylprednisolone pulse (15 mg/kg) at treatment start followed by oral prednisone (1 mg/kg/day) according to a tapering schedule. Treating physicians allowed to treat minor relapses with corticosteroids without referring the patient for randomization, as long as the prednisone dose did not exceed 0.5 mg/kg for 1 month. Patients in whom prednisone doses could not be tapered below 20 mg, those who failed to enter remission and those who relapsed were randomized to receive either 6 months of oral azathioprine (2mg/kg/day) or 6 cyclophosphamide pulses (0.6g/m2 D1, D15, D30 then every month)
