Details and patient eligibility

About

This is a multi-center, randomized, double-blind, placebo-controlled study. Study subjects are class III, IV, V, III+V, IV+V lupus nephritis patients, according to ISN/RPS 2003 classification of LN, with active lesion needing corticosteroid in combination with immunosuppressant therapy.

Subjects who meet the eligibility criteria during screening will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio: 25mg bid artesunate, 50mg bid artesunate or placebo plus standard of care (prednisone plus mycophenolate mofetil ［MMF］) for 6 month.

Full description

Lupus nephritis (LN) can be observed in up to 70% of SLE patients and is often associated with a poor long-term prognosis. Artesunate, one analogues of antimalarial agent artemisinin, have immunomodulatory properties that might be useful for treating autoimmune diseases including SLE. it is still lack of solid evidence from RCT to evaluate efficacy and safety of artesunate plus standard of care in active LN. Regarding no data could be referred to decide the sample size and optimal dosage, we designed this pilot study. The result and experience of pilot study will answer these questions, and guarantee the multicenter RCT to be conducted successfully.

This is a multi-center, randomized, double-blind, placebo-controlled study. Study subjects are class III, IV, V, III+V, IV+V lupus nephritis patients, according to ISN/RPS 2003 classification of LN, with active lesion needing corticosteroid in combination with immunosuppressant therapy.

Subjects who meet the eligibility criteria during screening will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio: 25mg bid artesunate, 50mg bid artesunate or placebo plus standard of care (prednisone plus mycophenolate mofetil ［MMF］) for 6 month.

All the subjects were asked to visit the hospital for weekly follow-up for four weeks, then monthly thereafter.
