A Study of Telitacicept for the Treatment of Moderately to Severely Active Systemic Lupus Erythematosus (REMESLE-2)

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease with heterogeneous manifestations and disease course. Despite advances in medical care, there are still significant unmet needs in SLE with diminished health-related quality of life (HRQoL), persistent disease activity, disease flares, intolerance to standard of care (SOC) therapies, and development of organ damage and co-morbidities.

Telitacicept is a fully human TACI-Fc fusion protein that targets B lymphocyte stimulator (BLyS) and a proliferating-inducing ligand (APRIL). Blocking the interaction of BLyS and APRIL with their cell membrane receptors (TACI, B-cell maturation antigen (BCMA), and B-cell activating factor receptor (BAFF-R) would inhibit B cell proliferation and maturation, suppresses immune responses and may alleviate autoimmune symptoms.

This is a multicenter, randomized, double-blind, placebo-controlled, phase 3 study to evaluate the efficacy and safety of telitacicept added to standard of care (SoC) therapy compared to placebo with SoC therapy in subjects with moderately to severely active SLE.
