Nearly half of patients on Gazyva plus standard therapy achieved a complete renal response (CRR), with a statistically significant and clinically meaningful improvement, compared to standard treatment alone
Analysis showed consistent CRR benefit across patient subgroups highlighting potential to treat a broad patient population with high unmet need
Gazyva is the only anti-CD20 monoclonal antibody in a phase III study to demonstrate CRR benefit, which is associated with preservation of kidney function and delay or prevention of end-stage kidney disease
South San Francisco, CA -- February 7, 2025 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY) announced today that a detailed analysis of its Phase III REGENCY trial of Gazyva® (obinutuzumab) in people with active lupus nephritis (LN) was published in the New England Journal of Medicine. The trial demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of complete renal response (CRR), showing that 46.4% of people treated with Gazyva plus standard therapy (mycophenolate mofetil and glucocorticoids) achieved CRR at 76 weeks compared with 33.1% of people treated with standard therapy alone (adjusted difference 13.4%, 95% CI, 2.0%-24.8%; p=0.0232). This was accompanied by clinically meaningful improvements in complement levels and reductions in anti-dsDNA, markers of disease activity and inflammation.
Data were presented at the World Congress of Nephrology (WCN) 2025 and are being shared with health authorities, including the U.S. Food and Drug Administration (FDA) and the European Medicines Agency.
“The fact that nearly half of lupus nephritis patients achieved a complete renal response, together with clinically meaningful benefits observed consistently across subgroups, indicates superior disease control with Gazyva compared to standard treatment alone,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “Lupus nephritis disproportionately affects younger women, mostly women of color, often leading to end-stage kidney disease. Our goal is to address this urgent need by providing a more effective treatment option.”
“The positive REGENCY study results confirmed the findings of an earlier trial that administration of obinutuzumab, a therapy which targets B cells, benefited patients with lupus nephritis more than standard treatment alone,” said Dr. Richard Furie, the Marilyn and Barry Rubenstein Chair in Rheumatology and Chief of the Division of Rheumatology at Northwell Health. “It is also gratifying to see that patients who received obinutuzumab were not only more likely to achieve the desired outcome but were able to taper corticosteroids at the same time.”
Gazyva’s safety profile was consistent with the well-characterized profile observed in its hematology-oncology indications. Key secondary endpoints showed that at week 76, patients who received Gazyva plus standard therapy were more likely to achieve CRR, with a successful reduction of corticosteroid use than standard therapy alone. In addition, a higher proportion of patients also showed improvement in proteinuric response when treated with Gazyva plus standard therapy versus standard therapy alone. These endpoints are important indicators for achieving better disease control in lupus nephritis. As seen in pre-specified subgroup analyses, a benefit in CRR with Gazyva over standard therapy alone was consistent across all subgroups of patients including indicators of more active lupus nephritis, Class IV lupus nephritis, concomitant Class V disease, higher baseline proteinuria levels, and/or greater serologic activity.
Further results for key secondary endpoints can be found in the table below and additional post hoc analysis is ongoing.
Key secondary endpoints | Obinutuzumab (n=135) Response % (95% CI) | Placebo (n=136) Response % (95% CI) | Treatment Difference (95% CI) | P value |

Proteinuric response at Week 76 (UPCR <0.8 g/g) | 55.5 (47.1, 64.0) | 41.9 (33.6, 50.2) | 13.7 (2.0, 25.4) | 0.0227 |
Change in eGFR from baseline, adjusted mean | 2.31 (2.71) | -1.54 (2.71) | 3.84 (-1.83, 9.51) | 0.1842 |

Lupus nephritis is a potentially life-threatening manifestation of an autoimmune disease that affects approximately 1.7 million people worldwide, predominantly women, mostly of color and childbearing age. Despite current treatment options, up to a third of people will develop end-stage kidney disease within 10 years, where dialysis or transplant are the only available options and the risk of mortality is high.
Gazyva is the only anti-CD20 monoclonal antibody to demonstrate a CRR benefit in a randomized phase III study in lupus nephritis. Based on data from the Phase II NOBILITY study, Gazyva was granted Breakthrough Therapy Designation by the U.S. FDA in 2019. In addition to REGENCY, Gazyva is being investigated in children and adolescents with lupus nephritis, people with membranous nephropathy, childhood-onset idiopathic nephrotic syndrome and systemic lupus erythematosus (SLE), an autoimmune disease that commonly affects the kidneys and can lead to lupus nephritis.
About Gazyva in Kidney Diseases
Gazyva® (obinutuzumab) is a Tye II engineered humanized monoclonal antibody designed to attach to CD20, a protein found on certain types of B cells. In lupus nephritis, disease-causing B cells drive persistent inflammation that damages the kidneys. We can target an underlying cause of lupus nephritis to help gain better control of the disease by depleting disease-causing B cells with Gazyva, aiming to protect the kidneys from further damage and potentially prevent or delay progression to end-stage kidney disease.
Gazyva is already approved in 100 countries for various types of lymphoma. In the United States, Gazyva is part of a collaboration between Genentech and Biogen.
About the REGENCY Study
REGENCY [NCT04221477] is a Phase III, randomized, double-blind, placebo-controlled, multicenter study investigating the efficacy and safety of Gazyva® (obinutuzumab) plus standard therapy (mycophenolate mofetil and glucocorticoids) in people with active/chronic International Society of Nephrology/Renal Pathology Society 2003 proliferative Class III or IV lupus nephritis, with or without Class V. The study enrolled 271 people, who were randomized 1:1 to receive either biannual intravenous dosing of Gazyva plus standard therapy or placebo plus standard therapy. REGENCY was designed based on robust Phase II data and conducted during the COVID-19 pandemic. The study population was representative of the real-world population of people with lupus nephritis. The primary endpoint was the proportion of people who achieved complete renal response (CRR) at 76 weeks. Key secondary endpoints included the proportion of people who achieved CRR at week 76 with successful reduction of corticosteroid use (prednisone taper); the proportion who achieved proteinuric response at 76 weeks; mean change in estimated glomerular filtration rate at 76 weeks; death or renal related events through week 76 and overall renal response at 50 weeks. Safety and tolerability were also assessed.
About Lupus Nephritis
Lupus nephritis is a potentially life-threatening manifestation of systemic lupus erythematosus, an autoimmune disease that commonly affects the kidneys. Lupus nephritis affects approximately 1.7 million people worldwide. Lupus nephritis has a profound impact on the lives and outlook of those affected and even with the latest treatments, the damage caused to the kidneys usually gets worse over time, with up to a third of people progressing to end-stage kidney disease within 10 years, where the only options are dialysis or transplant. Lupus nephritis predominantly affects women, mostly women of color and usually of childbearing age. Currently, there is no cure.
