GSK gets EMA panel recommendation to approve Benlysta for adult patients with active lupus nephritis

The CHMP opinion is based on data from the BLISS-LN (Efficacy and Safety of Belimumab in Adult Patients with Active Lupus Nephritis) study and the unmet need in this patient population. The BLISS-LN study is the largest and longest phase 3 study conducted in active LN, involving 448 adult patients. The study met its primary endpoint demonstrating that a statistically significant greater number of patients achieved Primary Efficacy Renal Response at two years (or 104 weeks) when treated with belimumab plus standard therapy compared to placebo plus standard therapy in adults with active LN (43% vs 32%, odds ratio (95% CI) 1.55 (1.04, 2.32), p=0.0311). Statistical significance compared to placebo across all four major secondary endpoints was achieved, including Complete Renal Response at Week 104 and Time to Renal-Related Event or Death. The adverse reactions observed in BLISS-LN were consistent with the known safety profile of Benlysta administered intravenously plus standard therapy in patients with SLE.
