Telitacicept Improves Clinical Response but Increases Infection Risk in Active SLE: NEJM

Telitacicept Improves Clinical Response in Active SLE

A 52-week trial of patients with active systemic lupus erythematosus (SLE) found that telitacicept produced a higher clinical response rate compared to placebo.

The study, published in the New England Journal of Medicine, evaluated the efficacy and safety of telitacicept, a dual B-cell activating factor (BAFF) and APRIL inhibitor.

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.

Author's summary: Telitacicept improves SLE response rates.
