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

Telitacicept Improves Clinical Response in Active SLE

In a 52-week trial, telitacicept showed a higher clinical response rate in patients with active systemic lupus erythematosus (SLE) compared to placebo.

Patients treated with telitacicept had significant improvements in disease activity scores, reflecting better control of lupus manifestations such as rash, arthritis, and serologic activity.

However, the treatment was 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 the increased risk of infections and other adverse effects.

Author's summary: Telitacicept improves SLE response rates.
