Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the safety of escalating dose levels of MEDI-507 in pediatric stem cell and bone marrow allograft recipients who have at least Grade II GvHD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase I, open-label dose escalation trial of MEDI-507 in pediatric SCT and BMT recipients with at least Grade II acute GvHD. All patients will receive steroid therapy and MEDI-507 for treatment of GvHD
