New hope for FSGS? obinutuzumab trial targets tough cases

NCT ID NCT04983888

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tested the drug obinutuzumab in 20 adults with a kidney disease called primary FSGS. The participants had not responded well to or could not take standard treatments like steroids. The goal was to see if obinutuzumab could reduce protein leakage in the urine, a sign of kidney damage. The drug was given as two IV infusions two weeks apart, with a repeat course at six months.

What this could mean

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

Active substance

Obinutuzumab (a monoclonal antibody given by IV infusion)

What this could lead to

If it works, this could offer a new treatment option for people with FSGS who do not respond to or cannot take standard therapies, potentially reducing protein in the urine and protecting kidney function.

What could go wrong

This is a small, early-phase trial with only 20 participants, so results may not apply to everyone. Obinutuzumab can cause infusion reactions and increase infection risk, and it is not yet proven to be better than existing treatments.
