Umbralisib (CAS 1532533-67-7; NIOSH HD Category 1) is the only approved kinase inhibitor to have simultaneously targeted two entirely distinct kinase families — PI3Kδ (lipid kinase; B-cell BCR signaling) and CK1ε (serine/threonine kinase; WNT pathway β-catenin degradation, circadian rhythm PER phosphorylation, lymphocyte function) — in a single molecule. No prior or subsequent approved kinase inhibitor has combined PI3Kδ inhibition with CK1ε inhibition. TG Therapeutics (New York NY) developed umbralisib under the developmental designation TGR-1202, receiving NDA 211140 accelerated approval February 5 2021 for CLL (with ublituximab), MZL, and FL. However, confirmatory trial data from UNITY-CLL showed a numerically unfavorable overall survival trend in the umbralisib arm, prompting TG Therapeutics to voluntarily withdraw umbralisib from the US market on March 31 2023 — the first full PI3K inhibitor US market exit and the first PI3K withdrawal based on unfavorable confirmatory OS data. Critically, the NIOSH HD Category 1 classification for CAS 1532533-67-7 persists after market withdrawal (the same pattern established by infigratinib, Attack #589), and post-withdrawal EHS platform deletion creates a secondary null-return hazard: when platforms remove withdrawn drugs from their databases, any residual or legacy umbralisib handled at clinical or research sites returns zero guidance, compounding the pre-existing OEL null for this NIOSH HD Category 1 compound.

TL;DR — Three Attack Surfaces: First Dual PI3Kδ/CK1ε + Voluntary US Withdrawal 2023 + NIOSH HD Persists Post-Withdrawal

Umbralisib First Dual PI3Kδ/CK1ε Inhibitor: CK1ε Biology, PI3Kδ B-Cell Activity, and Post-Withdrawal NIOSH HD Persistence

Umbralisib (TGR-1202; CAS 1532533-67-7) represents the only kinase inhibitor in the FDA-approved portfolio to have achieved regulatory approval through simultaneous inhibition of two kinases from completely distinct families: PI3Kδ (class I lipid kinase; activates PIP3/AKT B-cell survival signaling; IC50 ~22.2 nM) and CK1ε (casein kinase 1 epsilon; CSNK1E gene; serine/threonine kinase; IC50 ~34.0 nM). CK1ε is a constitutively active kinase in the CK1 family that phosphorylates multiple substrates with distinct biological outcomes: (1) PER1/2/3 circadian clock proteins (S662 in PER2) — CK1ε-mediated PER phosphorylation targets PER for β-TrCP ubiquitin ligase-mediated degradation, regulating circadian period length; (2) β-catenin (S45 priming phosphorylation in the APC/Axin destruction complex) — CK1ε phosphorylation of β-catenin initiates the sequential GSK3β phosphorylation cascade (T41, S37, S33) required for β-TrCP-mediated β-catenin ubiquitination, suppressing oncogenic WNT/β-catenin signaling in lymphoma; (3) IRAK4/MyD88-downstream pathway modulation — CK1ε may regulate innate immune signaling in tumor-associated macrophages and regulatory T cells, potentially reducing the Treg-mediated immune-mediated colitis burden that limits pure PI3Kδ inhibitors (idelalisib colitis ~19% Grade 3 vs umbralisib colitis ~4-6% Grade 3, attributed in part to CK1ε-mediated Treg modulation). The post-withdrawal NIOSH HD persistence hazard is the defining second-order risk: after TG Therapeutics removed Ukoniq from the market March 31 2023, EHS platforms began removing CAS 1532533-67-7 entries — any facility with legacy umbralisib in storage, research labs using umbralisib in ongoing studies, or clinical sites with unreturned patient supply now encounters CAS 1532533-67-7 → complete null, compounding the pre-existing lack of OEL. This post-withdrawal null-return pattern is identical to infigratinib (Attack #589) and confirms Glyphward's architectural advantage: it classifies NIOSH HD Category 1 drugs by mechanism class and regulatory history regardless of current market status.
