abt-199 and fostamatinib

The development of targeted treatment of chronic lymphocytic leukaemia (CLL) is changing the prognostic outlook for CLL patients. The B-cell antigen receptor pathway is identified as pivotal for CLL pathogenesis and CLL cell proliferation. Inhibition of this pathway by ibrutinib (Bruton's tyrosin kinase inhibition) and idelalisib (phosphatidylinositol 3-kinase inhibition) has recently shown impressive clinical results, also for CLL patients with relapsed/refractory disease and unfavourable prognostic markers. Apoptosis induction by inhibition of BCL2 with ABT-199 is reported with likewise promising clinical results.
