Systemic Lupus Erythematosus
Conditions
Brief summary
The purpose of this study is to evaluate the efficacy and safety of IMC-002 and IMM0306S in the treatment of active SLE.
Detailed description
This two-stage study consists of a multicenter dose-escalation study(Phase Ib)and a multicenter randomized, double-blind, placebo-controlled study(Phase II). Primary objectives of the dose-finding stage: 1) Evaluate the efficacy, safety, pharmacokinetic (PK) and pharmacodynamic (PD) profiles of intravenous IMC-002 and subcutaneous IMM0306S in adult patients with active systemic lupus erythematosus (SLE); 2) Determine the absolute bioavailability of subcutaneous IMM0306S relative to intravenous IMC-002 in adults with moderate-to-severe active SLE; 3) Select the recommended Phase II dose (RP2D). Primary objectives of the proof-of-concept (PoC) stage: Compare the efficacy of 1.2 mg/kg or 1.6 mg/kg IMC-002 versus placebo in adults with moderate-to-severe active SLE, and assess the efficacy and population PK (popPK) profiles of IMM0306S in patients with active SLE.
Interventions
intravenous injection of 0.8mg/kg、1.2mg/kg and1.6mg/kg
intravenous or subcutaneous injection of Placebo
subcutaneous injection of 2.0 mg/kg,4.0 mg/kg and 6.0mg/kg
