Efficacy and Safety of Telitacicept for Prevention of Flares in SLE Patients

This study is a randomized, double-blind, placebo-controlled single-center clinical trial. The aim of this study is to investigate the efficacy and safety of low-dose telitacicept for prevention of flares in SLE patients with low disease activity.

Background: There are still two major problems in the treatment of SLE: flare and long-term organ damage. BLISS-52 showed there was some reduction of flare (80% vs 71%) in belimumab , but the difference was not significant. Another study tested the efficacy and safety of atacicept for prevention of flares in patients with moderate-to-severe SLE in which analysis of atacicept 150 mg suggested benefit. Telitacicept , a BAFF/APRIL dual-target-inhibitor, which has been proved to be effective in treatment of SLE. But there is no study to show its effectiveness for prevention of flares in SLE patients with low disease activity. In this study, we take telitacicept as maintain treatment in stable SLE patients to investigate the efficacy and safety of low-dose telitacicept for prevention of flares in SLE patients with low disease activity.
