Study of MEDI 507 in the Treatment of Pediatric Patients
- Registration Number
- NCT00813618
- Lead Sponsor
- MedImmune LLC
- Brief Summary
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
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
