New drug aims to stop kidney transplant rejection without antibodies

NCT ID NCT07219043

First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

This study tests a drug called felzartamab in people who received a kidney transplant and later developed microvascular inflammation (MVI), a type of injury to small blood vessels in the new kidney that can lead to serious problems. The trial includes 81 participants who will receive either felzartamab or a placebo for 24 weeks, followed by an open-label phase where everyone gets the drug. Researchers will check for signs of inflammation through kidney biopsies and lab tests over about a year.

What this could mean

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

Active substance

felzartamab

What this could lead to

If successful, this could lead to a new treatment for isolated microvascular inflammation in kidney transplant recipients, potentially preserving kidney function and preventing graft loss.

What could go wrong

This is an early Phase 2 trial with only 81 participants, so results may not be conclusive. The drug may not reduce inflammation better than placebo, and there are risks from kidney biopsies and potential side effects.
