Targeting neoplastic B cells and harnessing microenvironment: the "double face" of ibrutinib and idelalisib.

ABSTRACT: Tyrosine kinase inhibitors (TKIs) targeting signaling molecules downstream B cell receptor (BCR) are powerfully spreading in the therapeutic landscape of B cell lymphoproliferative disease, due to a manageable toxicity profile and encouraging clinical effectiveness. In particular, ibrutinib, previously called PCI-32765, is a potent inhibitor of Bruton tyrosine kinase (Btk), recently approved for the treatment of relapsed mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL). Moreover, idelalisib (formerly GS-1101 and CAL-101) is a selective reversible inhibitor of the p110δ isoform of phosphoinositol 3 kinase (PI3K) approved for the treatment of patients with relapsed follicular lymphoma (FL) and CLL. These agents directly affect the neoplastic clone, disrupting the supportive
