GlaxoSmithKline and Human Genome Sciences receive European authorisation for Benlysta® (belimumab)


London UK, Rockville, Maryland, US -- GlaxoSmithKline (GSK) and Human Genome Sciences, Inc. (Nasdaq: HGSI) announced today that the European Commission (EC) has granted marketing authorisation for Benlysta®(belimumab) 10mg/kg as an add-on therapy in adult patients with active autoantibody-positive systemic lupus erythematosus (SLE), with a high degree of disease activity (e.g. positive anti-dsDNA and low complement), despite standard therapy1.

“The European approval of Benlysta represents a significant milestone, and we are very pleased to be able to provide physicians an additional therapeutic option for treating appropriate patients with this chronic disease,” said Dr Tony Hoos, Senior VP, European Medical Affairs, GSK.

“We and GSK are committed to making Benlysta available in countries worldwide,” said H. Thomas Watkins, President and Chief Executive Officer, HGS. “We are particularly honoured to be bringing this medicineforward in Europe, where a number of key academic research institutions were very important to its clinical development.”

The European summary of product characteristics (SmPC) lists patient groups which have not been studied with belimumab, including severe active CNS lupus or severe active lupus nephritis. Use of belimumab is therefore not recommended to treat these conditions. Caution should be exercised if belimumab is co-administered with other B cell targeted therapy or cyclophosphamide, as it has not been studied in combination with these agents.
