In a 52-week trial, telitacicept produced a higher clinical response rate in patients with active systemic lupus erythematosus (SLE) compared to placebo.
Patients treated with telitacicept achieved significantly greater improvements in disease activity scores, reflecting better control of lupus manifestations such as rash, arthritis, and serologic activity.
However, the treatment was also linked to increased rates of upper respiratory infections, decreased immunoglobulin levels, and injection-site reactions.
The trial demonstrated that telitacicept’s mechanism—targeting both BAFF and APRIL pathways—effectively suppresses B-cell overactivation, a key driver of autoimmunity in SLE.
The study highlights the need for careful monitoring due to potential side effects.
