A Phase 3 Trial of Telitacicept for Systemic Lupus Erythematosus

In this 52-week trial involving participants with active SLE who were receiving background therapy, the incidence of a clinical response was higher with telitacicept than with placebo. However, the incidence of upper respiratory infections, reduced immunoglobulin levels, and injection-site reactions was also higher with telitacicept.
