Positive Phase III Results for Genentech’s Gazyva Show Superiority to Standard Therapy Alone in People With Lupus Nephritis

In This Article:

– The REGENCY study met its primary endpoint, demonstrating statistically significant and clinically meaningful treatment benefits in people with active lupus nephritis –

– Gazyva is designed to target an underlying cause of lupus nephritis, aiming to prevent or delay progression to end-stage kidney disease –

Lupus nephritis is a potentially life-threatening manifestation of an autoimmune disease affecting 1.7 million people worldwide, primarily women; up to one-third of people on current treatments will progress to end-stage kidney disease within 10 years –

SOUTH SAN FRANCISCO, Calif., September 26, 2024--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today positive topline results from the Phase III REGENCY study of Gazyva® (obinutuzumab) in people with active lupus nephritis. In the study, a higher proportion of people treated with Gazyva plus standard therapy (mycophenolate mofetil and glucocorticoids) achieved a complete renal response (CRR) at 76 weeks compared to those treated with standard therapy alone. Safety was in line with the well-characterized profile of Gazyva. No new safety signals were identified.

"Gazyva achieved a robust complete renal response rate in lupus nephritis, which is associated with long-term preservation of kidney function and delay or prevention of end-stage kidney disease," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "Since dialysis or transplants are often required for patients with advanced kidney disease, these findings could represent an important step forward for people living with this devastating disease."

"I am very excited about today’s announcement that the Phase III REGENCY study has met its primary endpoint," said Dr. Brad H. Rovin, Director of Nephrology and Medical Director of the Center for Clinical Research Management at The Ohio State University Wexner Medical Center, and investigator for the REGENCY study. "The results of REGENCY are compelling. Obinutuzumab could offer the lupus community an effective new treatment option for controlling this difficult disease that can be associated with high morbidity for individuals living with lupus."

Two key secondary endpoints showed statistically significant and clinically meaningful benefits with Gazyva – the endpoint proportion of patients achieving CRR with a successful reduction of corticosteroid use, and an improvement in proteinuric response (both at 76 weeks). These endpoints are important indicators for achieving better disease control in lupus nephritis. Other secondary endpoints were not statistically significant, but numerically greater responses were observed for Gazyva in several endpoints.*
