Roche announced statistically significant and clinically meaningful results from the phase III ALLEGORY study of Gazyva/Gazyvaro (obinutuzumab) in adults with systemic lupus erythematosus (SLE) on standard therapy.
The study met its primary endpoint showing a higher percentage of people achieved a minimum four-point improvement in SLE Responder Index 4 (SRI-4) at one year (52 weeks) with Gazyva/Gazyvaro versus standard therapy. SRI is a tool that assesses changes in disease severity, symptoms and physical condition to indicate whether treatment is effective at controlling disease activity. All key secondary endpoints were also met. No new safety signals were identified, and safety was in line with the well-characterized profile of Gazyva/Gazyvaro.
All key secondary endpoints were met, with results showing statistically significant and clinically meaningful benefits with Gazyva/Gazyvaro versus standard therapy including British Isles Lupus Assessment Group based Composite Lupus Assessment (BICLA) response at week 52, sustained corticosteroid control from week 40 to 52, sustained SRI-4 from week 40 to 52, a six-point improvement in SLE disease activity score (SRI-6) at 52 weeks, and time to first flare over 52 weeks as defined by the British Isles Lupus Assessment Group (BILAG) index.
Data will be presented at an upcoming medical meeting and shared with health authorities as soon as possible, including the US Food and Drug Administration and the European Medicines Agency. If approved, Gazyva/Gazyvaro would be the first anti-CD20 therapy for SLE to directly target B cells, an underlying cause of disease.
ALLEGORY is the third positive phase III study for Gazyva/Gazyvaro in immune-mediated diseases, in addition to REGENCY in lupus nephritis and INShore in idiopathic nephrotic syndrome. This growing evidence suggests that Gazyva/Gazyvaro, designed to attack and destroy targeted B cells, both directly and together with the body's immune system, may help address disease activity across a spectrum of autoimmune or immune-related diseases.
In addition to SLE, Gazyva/Gazyvaro is being investigated in children and adolescents with lupus nephritis, as well as adults with membranous nephropathy.
