Study of a Humanized Antibody Initiated 2 Months After an HLA Matched Allogenic Stem Cell Transplantation

Summary

This study will determine the Maximal Tolerated Dose if any and the recommended dose for phase 2 of monalizumab, a monoclonal antibody directed against the CD94/NKG2A receptor, after allogenic stem cell transplantation. All patients will receive one single intravenous administration of one of the four doses of monalizumab.
