About

A prospective, randomized, multicenter, open-label, parallel-arm Study to compare effectiveness of mycophenolate mofetil versus cyclophosphamide in the Induction Therapy of pediatric patients with Active Proliferative Lupus Nephritis in Chinese population

Full description

Scattered research in adults showed that both mycophenolate mofetil (MMF) and cyclophosphamide (CYC) can be used in the induction therapy of lupus nephritis. however data is limited in children.Therefore, the purpose of this study is to observe and compare the efficacy and safety of MMF and CYC as induction therapy for children with proliferative lupus nephritis through a multi-center open randomized controlled study.
