Duvelisib is an orally bioavailable, highly selective and potent small molecule inhibitor of the delta and gamma isoforms of phosphoinositide-3 kinase (PI3K) with potential immunomodulating and antineoplastic activities. Upon administration, duvelisib prevents the activation of the PI3K delta/gamma-mediated signaling pathways which may lead to a reduction in cellular proliferation in PI3K delta/gamma-expressing tumor cells. Unlike other isoforms of PI3K, the delta and gamma isoforms are overexpressed primarily in hematologic malignancies and inflammatory and autoimmune diseases. By selectively targeting these PI3K isoforms, PI3K signaling in normal, non-neoplastic cells is minimally or not affected which would result in a more favorable side effect profile.

Duvelisib is an oral inhibitor of phosphatidylinositol 3-kinase (PI3K) that is approved for use in relapsed or refractory chronic lymphocytic leukemia (CLL) and for follicular lymphoma. Duvelisib is associated with a high rate of serum enzyme elevations during therapy and with occasional concurrent rise in serum bilirubin and is a suspected but not proven cause of clinically apparent acute liver injury.

Duvelisib, also known as IPI-145 and INK-1197, is a small-molecule inhibitor of phosphoinositide-3 kinases that was designed initially to prove that simultaneous inhibition of the isoforms delta and gamma can produce a broad adaptative and innate immune cell inhibitory activity. All the work around duvelisib showed that this agent is a potent inhibitor of both forms. Duvelisib was developed by Verastem, Inc and FDA approved on September 24, 2018.
