A Study of IMC-002 for the Treatment of Active Systemic Lupus Erythematosus

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.
