Approved IV Drug Reduces Lupus Symptoms, Clinical Trial Finds

Key TakeawaysAn already approved IV drug can significantly reduce lupus symptomsMore than three-quarters of patients taking Gazvya had a significant improvement in their symptomsGazvya is already approved to treat lupus-related kidney inflammation.TUESDAY, March 10, 2026 (HealthDay News) — An already-approved IV drug significantly reduces the symptoms of lupus, a new clinical trial showed.More than three-quarters of lupus patients taking obinutuzumab (Gazvya) had a significant improvement in their symptoms after a year on the drug, researchers reported March 6 in The New England Journal of Medicine.The drug also improved time between lupus flares, and had a more than doubled remission rate compared to placebo, researchers said.Gazvya already is approved to treat lupus-caused kidney inflammation. The drug prompts the immune system to attack and destroy B-cells, which produce the antibodies that cause lupus.The clinical trial “represents one of the most compelling late-stage successes in years for the treatment of patients with systemic lupus erythematosus (SLE), showing important evidence that targeting B cells can deliver significant reductions in disease activity,” said lead researcher Dr. Richard Furie, chief of rheumatology at Northwell Health in New Hyde Park, New York.“We are seeing the potential to deliver more robust and sustained disease control with less reliance on steroids,” Furie said in a news release. “These benefits matter profoundly to patients, physicians and families, marking Gazyva as an important step forward in the treatment of this autoimmune disease.”Lupus is a chronic autoimmune disease that causes the immune system to turn on the body, attacking primarily the skin, joints and internal organs like the kidneys or the heart, according to the Lupus Foundation of America.Lupus affects more than 3 million people worldwide, mostly women diagnosed between ages 15 and 45, researchers said in background notes.Frequent lupus flares can cause irreversible organ damage. About half of lupus patients develop lupus nephritis – the kidney complication for which Gazvya is approved – within five years of diagnosis.For the new study, researchers recruited more than 300 patients with lupus receiving standard therapy for the disease, and randomly assigned half to take Gazvya and the rest a placebo.The patients received IV infusions of either Gazvya or a placebo on day one of the trial, followed with repeat doses at weeks two, 24 and 26.After a year, 77% of patients with Gazvya had a significant reduction in their lupus, compared with 54% of those on placebo.About 35% of those on Gazvya went into remission, compared with 14% of those on placebo, results showed.Patients taking Gazvya had a higher rate of serious side effects, 17% versus 14%, researchers found. The most common adverse events were pneumonia, upper respiratory tract infection and urinary tract infection, researchers reported.One death occurred among the Gazvya patients, and three deaths among patients on placebo. The Gazvya death involved pneumonia.“For decades, people living with SLE have faced a cycle of unpredictable disease activity, limited treatment options and long-term steroid burden,” Dr. Levi Garraway, chief medical officer for the Roche Group, said in a news release. The Roche Group makes Gazvya and funded the clinical trial.“These results … show that Gazyva can provide significant, clinically meaningful and sustained disease control, which is critical to preventing life-threatening damage to major organs,” Garraway said. “We look forward to working with health authorities around the world to bring this potentially transformative new treatment to patients with lupus as quickly as possible.”More informationThe Lupus Foundation of America has more on lupus.SOURCES: Roche Group, news release, March 6, 2026; The New England Journal of Medicine, March 6, 2026 .What This Means For YouLupus patients should talk to their doctor about whether Gazvya could help them..Sign up for our weekly HealthDay newsletter
