Outcomes of patients with systemic lupus erythematosus treated with belimumab: a post hoc efficacy analysis of five phase III clinical trials by British Isles Lupus Assessment Group-based Combined Lupus Assessment criteria.

ABSTRACT:

Objectives

To determine belimumab efficacy assessed using the British Isles Lupus Assessment Group (BILAG)-based Combined Lupus Assessment (BICLA) in patients with systemic lupus erythematosus (SLE) from phase III belimumab randomised controlled trials (RCTs).

Methods

A post hoc analysis was carried out on five RCTs in active adult SLE: four with intravenous (BLISS-52, BLISS-76, BLISS-NEA, EMBRACE) and one with subcutaneous belimumab (BLISS-SC). The 52-week landmark assessments were analysed across trials. Treatment response was defined according to BICLA criteria (BILAG improvement; no worsening of disease activity based on BILAG and Systemic Lupus Erythematosus Disease Activity Index-2K; no deterioration in Physician's Global Assessment ≥0.3 (scale: 0-3); no treatment fail
