MedKoo CAT#: 205744

CAS#: 1201438-56-3

Description: Duvelisib, also known as IPI-145 and INK-1197, 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, PI3K delta/gamma inhibitor IPI 145 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.

Additional Information

History: In July 2010, Intellikine announced a collaborative partnership with Infinity Pharmaceuticals, Inc. under which Infinity obtained global development and commercialization rights to IntellikineÂ’s portfolio of inhibitors of the delta and gamma isoforms of phosphoinositide-3-kinase (PI3K). Among these inhibitors is IPI-145, an orally available PI3Kδ/γ inhibitor which entered clinical study in October 2011.  The first Phase 1 trial of IPI-145 is a double-blind, randomized, placebo-controlled study designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple escalating doses of IPI-145 in healthy adult subjects.  The second Phase 1 trial is an open-label, dose-escalation study designed to evaluate the safety, pharmacokinetics and clinical activity of IPI-145 in patients with advanced hematologic malignancies. Following the determination of the maximum tolerated dose in the dose escalation phase, an expansion phase will follow in patients with selected hematologic malignancies.
