Summary
This study tests whether giving more doses of the drug abatacept after a stem cell transplant can better prevent graft-versus-host disease (GVHD), a serious condition where donor cells attack the patient's body. About 160 people receiving a partially matched donor transplant will get either 4 or 8 doses of abatacept plus standard care. Researchers will track who stays free of severe GVHD and relapse for at least one year.
