Title: A Prospective, Randomized, Active Controlled, Parallel Group, Multi-center Trial to Assess the Efficacy and Safety of Mycophenolate Mofetil (MMF) in Inducing Response and Maintaining Remission in Subjects With Lupus Nephritis.
Brief Summary: This 2 arm study assessed the efficacy of Mycophenolate Mofetil (MMF; CellCept) compared to cyclophosphamide in inducing a response in patients with lupus nephritis, and the long term efficacy of MMF compared to azathioprine in maintaining remission and renal function. Patients were randomized to receive either MMF (1.5 g twice daily \[bid\]) or cyclophosphamide (0.5-1.0 g/m\^2 in monthly pulses) in the induction phase. Those patients meeting criteria for response were re-randomized for entry into the maintenance phase, to receive either MMF (1 g bid) or azathioprine (2 mg/kg/day).
