Brief summary
To evaluate therapeutic response to MMF treatment in patients with International Society of Nephrology/Renal Pathology Society (ISN/RPS) class III or IV lupus nephritis. Mycophenolic acid levels at 1-hour post dose will be monitored monthly up to 6 months.
Interventions
Drug : Mycophenolate Mofetil. Starting doses : 1000-1500 mg/day with titration based on Mycophenolic 1-hour post dose level.
