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.

Condition Intervention Phase
Polyarteritis Nodosa Microscopic Polyangiitis Drug: azathioprine Drug: cyclophosphamide Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Number of events (failures, relapses and/or deaths) occurring in each group, defining the disease-free survival rate, measured at study end (mean follow-up of 5 years)

Secondary Outcome Measures:
  • Overall survival, relapse rate and adverse events, measured at study end (mean follow-up of 5 years)

Estimated Enrollment: 124
Study Start Date: July 1996
Detailed 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)
