Mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) are characterized by CD5+ B-cell accumulation in secondary lymphoid tissues. MCL and CLL B-cells depend upon B-cell receptor (BCR) signaling, tumor microenvironment support, and defective apoptosis mechanisms for expansion and survival. Targeted inhibitors of key proteins involved in proliferation/survival signaling (BTK, PI3K, BCL2) are commonly used in patients. However, multi-therapy resistant MCL and CLL underscores the need for novel therapeutic approaches. Recent studies have demonstrated pre-clinical activity of triple-axis inhibitors capable of concomitantly disrupting PI3K and BTK kinase activity and BRD4-mediated oncogene expression in B-cell malignancies. Here, we demonstrate the enhanced efficacy of a next-generation triple inhibitor (TRPi) in incurable, aggressive (MCL) and indolent (CLL) B-cell malignancies.
