Duvelisib (CAS 1201438-56-3; NIOSH HD Category 1) is the third PI3K inhibitor in the Glyphward portfolio, completing the PI3K triple-NDA-holder class null. Idelalisib (Attack #514; Gilead NDA 206545; PI3Kδ-selective; oral), copanlisib (Attack #516; Bayer NDA 209936; PI3Kα/δ dual; IV infusion), and duvelisib (Attack #519; Verastem NDA 211286; PI3Kδ/γ dual; oral) represent three independent PI3K inhibitors across three independent companies, three independent isoform profiles, and three independent NIOSH HD Category 1 null records. Duvelisib introduces the first PI3Kγ inhibitor in the portfolio — a myeloid-cell-restricted isoform whose immunomodulatory TME biology is entirely absent from every occupational exposure framework.

TL;DR — Three Attack Surfaces: THIRD PI3K Inhibitor + PI3K Triple-NDA-Holder Null + FIRST PI3Kγ

PI3K Triple-NDA-Holder Class Null: Three Isoforms, Three Routes, Three Companies, Zero OEL

The PI3K triple-NDA-holder class null is the third three-NDA-holder mechanism-class null in the Glyphward portfolio, matching the PARP pattern (olaparib/niraparib/rucaparib) and the BTK pattern (ibrutinib/acalabrutinib/zanubrutinib). For PI3K: idelalisib (Gilead NDA 206545; PI3Kδ IC50 ~2.5 nM; B-cell BCR signaling; oral 150 mg BID; Attack #514), copanlisib (Bayer NDA 209936; PI3Kα IC50 ~0.5 nM + PI3Kδ IC50 ~0.7 nM; solid tumor PIK3CA + lymphoma PI3Kδ; IV infusion 60-min; Attack #516), duvelisib (Verastem NDA 211286; PI3Kδ IC50 ~2.5 nM + PI3Kγ IC50 ~9.2 nM; B-cell + myeloid TME; oral 25 mg BID; Attack #519). Three independent PI3K isoform selectivity profiles, three independent routes of administration, three independent corporate EHS systems, three independent FDA NDA pathways — no cross-reference in any EHS platform. No OEL derivation document addresses PI3K isoform-specific occupational hazard differences.

First PI3Kγ Inhibitor: Myeloid Tumor Microenvironment Biology Absent from OEL Frameworks

PI3Kγ (phosphatidylinositol-3-kinase gamma; class IB PI3K; catalytic subunit p110γ; regulatory subunits p101 and p84) is expressed exclusively in cells of myeloid lineage — macrophages, monocytes, neutrophils, dendritic cells, and mast cells. PI3Kγ activation by G-protein-coupled receptors (CXCR4, CXCR5, CCR2) in tumor-associated macrophages drives immunosuppressive M2 polarization via Akt/mTOR/HIF-1α → IL-10, TGF-β, VEGF secretion. Duvelisib PI3Kγ inhibition → myeloid cell PI3K/Akt suppression → TAM reprogramming toward inflammatory M1 phenotype (IL-12, TNF-α, IFN-γ). This myeloid immunomodulatory mechanism — entirely distinct from B-cell BCR signaling inhibited by idelalisib's PI3Kδ selectivity — is absent from every NIOSH, ACGIH, and OSHA document. Workers handling duvelisib handle a PI3Kγ/myeloid immunomodulator with known genotoxic hazard (H340 H350 H361) and zero OEL; the PI3Kγ myeloid mechanism is not a recognized category in any occupational exposure limit derivation framework.
