New drug zanubrutinib takes on kidney disease in major trial
NCT ID NCT05707377
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 3 times
Summary
This study tests whether the drug zanubrutinib can help people with primary membranous nephropathy, a kidney disease that causes protein leakage. About 178 participants will receive either zanubrutinib or the standard drug tacrolimus. The goal is to see if zanubrutinib reduces protein in urine and leads to complete remission of the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- zanubrutinib
- What this could lead to
- If successful, zanubrutinib could offer a new treatment option for people with this kidney disease, potentially reducing protein leakage and preserving kidney function.
- What could go wrong
- This is a mid-stage trial with 178 participants, so results are not yet proven. Zanubrutinib may not work better than the current drug, and side effects like infection or bleeding are possible.

Inclusion Criteria: * Biopsy-confirmed PMN within 5 years before the initial screening (ie, the day the informed consent is signed) * UPCR (based on 24-hour urine collection) \> 3.5 at initial screening and at confirmation assessment * Treatment with a maximally tolerated or allowed dose of an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) for ≥ 24 weeks before randomization (12 weeks before initiation of study drug for Part 1) and with adequate blood pressure control (blood pressure \< 130/80 mmHg, measured on ≥ 2 occasions \[not on the same day\] within 4 weeks before the assignment of study treatment) * Anti-PLA2R antibody \> 50 RU/mL at confirmation assessment (Part 1 only) Exclusion Criteria: * Participants with a secondary cause of membranous nephropathy * Type 1 or 2 diabetes mellitus with hemoglobin A1c (HbA1c) ≥ 7% at screening * Severe renal disease as determined by rapid decline in eGFR (defined as \> 15 mL/min/1.73m\^2 within 24 weeks prior to randomization, not otherwise explained) * A known history of a primary immunodeficiency or an underlying condition such as human immunodeficiency virus (HIV) infection or splenectomy that predisposes the participant to infections * Patients at risk for tuberculosis at screening * Known infection with serologic status reflecting active or chronic hepatitis B virus infection, or presence of hepatitis C virus antibody * Severe hepatic insufficiency (Child-Pugh C) * Clinically significant cardio-cerebrovascular diseases Note: Other protocol defined Inclusion/Exclusion criteria may apply.
