Can a targeted antibody boost kidney remission in lupus?
NCT ID NCT07767188
First seen Aug 17, 2026 · Last updated Aug 27, 2026 · Updated 3 times
Summary
This phase 3 trial is testing whether adding the drug obinutuzumab to the standard treatment (mycophenolate mofetil and corticosteroids) can improve outcomes for people with active lupus nephritis, a serious kidney complication of lupus. The study will enroll 70 adults aged 18-65 with confirmed active lupus nephritis. Participants will receive obinutuzumab infusions at specified intervals over a year, alongside standard therapy. The main goal is to see how many achieve a complete renal response by week 76, meaning their kidney function stabilizes and protein in the urine drops to a healthy level.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- obinutuzumab
- What this could lead to
- If successful, this could lead to a new first-line treatment option for lupus nephritis that improves kidney outcomes.
- What could go wrong
- This is a single-arm trial without a placebo control, so results may be influenced by the standard therapy alone. Obinutuzumab can have side effects, including infusion reactions and increased infection risk.
