简要总结
A Study of Bafetinib as Treatment for Patients with Relapsed or Refractory B-Cell Chronic Lymphocytic Leukemia (B-CLL).
详细描述
Bafetinib is a dual protein kinase inhibitor, targeting both bcr/abl and Lyn kinases. B-cell chronic lymphocytic leukemia cells overexpress Lyn kinase compared to normal B lymphocytes as well as acute leukemias (ALL and AML), and inhibition of Lyn kinase induces apoptosis in cultures of B-CLL cells. Thus, bafetinib may stop the growth of B-CLL cells by inhibiting Lyn kinase, the molecule that couples the B cell receptor to downstream signaling.
