OVER THE LAST FEW years, significant advances were made in the treatment of patients with chronic lymphocytic leukemia (CLL). Several novel therapies, most of them oral, have now been approved by the Food and Drug Administration. These include Imbruvica (ibrutinib), a Bruton’s tyrosine kinase (BTK) inhibitor; Venclexta (venetoclax), a B-cell lymphoma-2 (BCL2) inhibitor; and Zydelig (idelalisib), a phosphoinositide 3-kinase (PI3K) inhibitor.
