New drug combo aims to tame deadly transplant complication

NCT ID NCT04339101

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

Summary

This phase II trial tested whether adding the drug itacitinib to standard medications (tacrolimus and sirolimus) can better prevent graft-versus-host disease (GVHD) in 59 patients with blood cancers receiving donor stem cell transplants. GVHD occurs when donor immune cells attack the recipient's body. The study looked at safety and how well the combination worked to keep patients free from GVHD and relapse one year after transplant.
