Can a cancer drug help heart transplant patients get a match?

NCT ID NCT05300451

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether the drug daratumumab can lower high levels of immune system antibodies that make it hard for some people to find a matching heart donor. Ten adults waiting for a heart transplant will receive daratumumab injections to see if their antibody levels drop enough to allow a successful transplant. The goal is to reduce the risk of organ rejection and improve chances of receiving a donor heart.

What this could mean

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

Active substance
daratumumab and hyaluronidase-fihj (DARZALEX FASPRO)
What this could lead to
If successful, this could help people with high antibody levels become eligible for a heart transplant and reduce the risk of organ rejection.
What could go wrong
This is a very small early-phase trial with only 10 participants, so results may not apply to everyone. Daratumumab can cause infusion reactions and increase infection risk.
