Abstract: In some embodiments, the present invention relates to novel small molecule inhibitors that block the CXCR4-SDF-1 signaling pathway by directly inhibiting members of the Tec family of kinases, namely Bruton's tyrosine kinase (BTK), and their use in treating diseases in which pathogenesis is mediated by the CXCR4/SDF-1 signaling pathway.

Abstract: In some embodiments, the invention includes a therapeutic combination of a phosphoinositide 3-kinase (PI3K) inhibitor, including PI3K inhibitors selective for the ?- and ?-isoforms and selective for both ?- and ?-isoforms, and a Bruton's tyrosine kinase (BTK) inhibitor. In some embodiments, the invention includes therapeutic methods of using a BTK inhibitor and a PI3K-? inhibitor to treat solid tumor cancers by modulation of the tumor microenvironment, including macrophages, monocytes, mast cells, helper T cells, cytotoxic T cells, regulatory T cells, natural killer cells, myeloid-derived suppressor cells, regulatory B cells, neutrophils, dendritic cells, and fibroblasts.

Abstract: Therapeutic compositions and methods of using the compositions, including combinations of a Bruton's tyrosine kinase (BTK) inhibitor, a phosphomositide 3-kinase (PI3K) inhibitor, including PI3K inhibitors selective for the ?- and ?-isoforms and selective for both y- and ?-isoforms (PI3K-?,?, PI3K-?, and PI3K-?, a programmed death 1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitor, and/or a Janus kinase-2 (JAK-2) inhibitor are described. In certain embodiments, the invention includes therapeutic methods of using a PD-1 monoclonal antibody and a BTK inhibitor. In other embodiments, the invention includes therapeutic methods of using a PD-L1 monoclonal antibody and a BTK inhibitor. In other embodiments, the invention includes therapeutic methods of using a PD-1 inhibitor, a BTK inhibitor, and a PI3K˜? inhibitor. In other embodiments, the invention includes therapeutic methods of using a PD-L1 inhibitor, a BTK inhibitor, and a PI3K˜? inhibitor.

In certain embodiments, the invention includes therapeutic combinations of a cyclin-dependent kinase-4/6 (CDK4/6) inhibitor and a BTK inhibitor, a PI3K-? inhibitor and a BTK inhibitor, a JAK-2 and a BTK inhibitor, and a JAK-2, PI3K-?, and BTK inhibitor.

Abstract: Therapeutic combinations of a Janus kinase-2 (JAK-2) inhibitor, a Bruton's tyrosine kinase (BTK) inhibitor, and/or a phosphoinositide 3-kinase (PI3K) inhibitor, including PI3K inhibitors selective for the ?- and ?-isoforms and selective for both ?- and ?-isoforms, are described. In some embodiments, the invention provides pharmaceutical compositions comprising combinations of (1) a PI3K-? inhibitor and a BTK inhibitor, (2) a JAK-2 inhibitor and a BTK inhibitor, or (3) a JAK-2 inhibitor, PI3K-? inhibitor, and BTK inhibitor, and methods of using the pharmaceutical compositions for treating a disease, in particular a cancer.

Abstract: Therapeutic methods of treating chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) are described. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating subtypes of CLL and SLL using a BTK inhibitor, including subtypes of CLL in patients sensitive to thrombosis and subtypes of CLL that increase monocytes and NK cells in peripheral blood after treatment with a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a combination of a BTK inhibitor and an anti-CD20 antibody.
