Core Insights - Roche announced statistically significant and clinically meaningful results from the phase III ALLEGORY study of Gazyva®/Gazyvaro® (obinutuzumab) for adults with systemic lupus erythematosus (SLE), demonstrating a higher percentage of patients achieving a minimum four-point improvement in SLE Responder Index 4 (SRI-4) at one year compared to standard therapy [1][2] Group 1: Study Results - The ALLEGORY study met its primary endpoint, showing that Gazyva/Gazyvaro led to a higher percentage of patients achieving SRI-4 at 52 weeks [1] - All key secondary endpoints were also met, including statistically significant improvements in BICLA response, sustained corticosteroid control, sustained SRI-4, a six-point improvement in SLE disease activity score (SRI-6), and time to first flare [2][4] - The study involved approximately 300 participants, randomized to receive Gazyva/Gazyvaro or placebo for up to one year, followed by an open-label period [6] Group 2: Disease Context - Systemic lupus erythematosus (SLE) affects over three million people globally, primarily women aged 15 to 45, with a significant impact on women of color [2][7] - Around 50% of SLE patients progress to lupus nephritis within five years of diagnosis, which can lead to life-threatening kidney complications [2][7] Group 3: Future Implications - If approved, Gazyva/Gazyvaro would be the first anti-CD20 therapy for SLE targeting B cells, addressing a key driver of inflammation and disease activity [4][5] - Roche aims to share the data with global health authorities, including the US FDA and the European Medicines Agency, to expedite the potential new standard of care [2][5] - The ALLEGORY study is the third positive phase III study for Gazyva/Gazyvaro in immune-mediated diseases, indicating its potential across a spectrum of autoimmune conditions [2][4]
