Successful second allogeneic stem cell transplantation in second remission induced by dasatinib in a child with Philadelphia chromosome positive acute lymphoblastic leukemia.

We report on the use of dasatinib, a second-generation bcr-abl kinase inhibitor, in a child in early relapse of Philadelphia chromosome positive acute lymphoblastic leukemia after hematopoietic stem cell transplantation. This patient benefited from the use of dasatinib obtaining of a complete molecular response which allowed a second successful transplant. Moreover, dasatinib was well tolerated in this heavily pretreated patient.
