Novel Pharmacotherapies for B-Cell Lymphomas and Leukemias

Novel pharmacotherapeutic agents were recently approved for treatment of low-grade B-cell neoplasms, and many other agents are under investigation. Several agents have demonstrated impressive activity in targeting malignant B-cell processes and specific pathways, all with the potential to expand our ability to effectively treat B-cell malignancies. The inhibitors of several cell regulatory proteins, including Bruton tyrosine kinase (Btk), phosphoinositide 3-kinase (PI3-K), B-cell lymphoma/leukemia-2 (Bcl-2), and histone deacetylases, as well as immunomodulatory agents are a few of the many pharmacotherapeutic agents under study. A comprehensive review and assessment is presented of the current pharmacotherapies under investigation targeting B-cell lymphomas and leukemias.
