NCT ID NCT03949855

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 2 trial tests whether adding belimumab to standard rituximab treatment helps more people with primary membranous nephropathy achieve remission. The study enrolls 58 adults with confirmed disease. Belimumab targets new immune cells, while rituximab depletes existing ones, aiming to reduce kidney damage.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

belimumab (Benlysta) and rituximab

What this could lead to

If successful, this combination could offer a more effective treatment for membranous nephropathy, potentially leading to longer-lasting remission with fewer side effects.

What could go wrong

This is a small Phase 2 trial, so results may not apply to all patients. Neither drug is FDA-approved for this condition, and combining them may increase infection risk or other side effects.
