Overview

Generic Name(s):
idelalisib
Trade Name(s):
Zydelig
NCI Definition [1]:
An orally bioavailable, small molecule inhibitor of the delta isoform of the 110 kDa catalytic subunit of class I phosphoinositide-3 kinase (PI3K) with potential immunomodulating and antineoplastic activities. Idelalisib inhibits the production of the second messenger phosphatidylinositol-3,4,5-trisphosphate (PIP3), preventing the activation of the PI3K signaling pathway and inhibiting tumor cell proliferation, motility, and survival. Unlike other isoforms of PI3K, PI3K-delta is expressed primarily in hematopoietic lineages. The targeted inhibition of PI3K-delta is designed to preserve PI3K signaling in normal, non-neoplastic cells.

Biomarker-Directed Therapies

Idelalisib has been investigated in 8 clinical trials, of which 7 are open and 1 is closed. Of the trials investigating idelalisib, 4 are phase 1 (3 open), 1 is phase 1/phase 2 (1 open), 2 are phase 2 (2 open), and 1 is phase 3 (1 open).

CD19 Expression is the most frequent biomarker inclusion criterion for idelalisib clinical trials.

Follicular lymphoma, acute lymphoblastic leukemia, and acute myeloid leukemia are the most common diseases being investigated in idelalisib clinical trials [2].
