Efficacy and Safety of Telitacicept in the Treatment of Systemic Sclerosis

Официальное название

The Efficacy and Safety of Telitacicept in the Treatment of Early Diffuse Cutaneous Systemic Sclerosis: a Multicenter, Open-label, Randomized Controlled Study

Обзор

This study is a prospective, open-label, randomized, controlled, multi-center clinical trial. The aim of this study is to investigate the efficacy and safety of Telitacicept in adults with early diffuse cutaneous systemic sclerosis (dcSSc), with Mycophenolate Mofetil (MMF) administered as a background treatment.

Вмешательства

• Препарат Telitacicept
  Telitacicept is fusion protein comprising a recombinant transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI) receptor fused to the fragment crystallizable (Fc) domain of human immunoglobulin G (IgG). Telitacicept binds to and neutralizes the activity of two cell-signalling molecules, B-lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL), thereby suppressing the development and survival of plasma cells and mature B cells. Telitacicept will be
• Препарат Mycophenolate Mofetil
  All patients will receive background therapy with Mycophenolate Mofetil (MMF), administered orally at a dose of 0.5g twice daily for 48 weeks.
