Primary Outcome Measures:
  • To evaluate the response rate (complete and partial), in subjects with relapsed or refractory B-Cell CLL [ Time Frame: Upto 6 months or disease progression ]

Secondary Outcome Measures:
  • Adverse Events [ Time Frame: 1 year ]

Enrollment: 20
Study Start Date: June 2010
Study Completion Date: April 2013
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bafetinib Drug: bafetinib
250 mg orally twice daily. Treatment continues until clinically significant disease progression or unacceptable toxicity is documented.
Other Name: INNO-406

Detailed Description:
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.
