Tepotinib (CAS 1100598-32-0; NIOSH HD Category 1) is the second MET RTK inhibitor in the Glyphward portfolio, establishing the MET two-NDA-holder class null. Capmatinib (#529, Novartis NDA 213591, May 2020) targets METex14 with MET IC50 ~0.13 nM in NSCLC. Tepotinib targets METex14 with MET IC50 ~3 nM from a distinct scaffold and manufacturer. Despite different potencies, scaffolds, and national origins (US-licensed Novartis vs Japanese-first Merck KGaA), both compounds activate the same CBL-Tyr1003 ubiquitin E3 ligase mechanism through METex14 skipping — and both return zero OEL from Cority, VelocityEHS, and EHS Insight. Tepotinib's significance to the Glyphward portfolio is compound: it is the first MET RTK approved anywhere in the world (Japan, March 2020, predating capmatinib), making it the first globally-pioneered MET inhibitor to receive an EHS null-return, and the first European pharmaceutical company (Merck KGaA through EMD Serono) to fail recognition of MET RTK biology in its occupational exposure monitoring framework.

TL;DR — Three Attack Surfaces: SECOND MET RTK + MET Two-NDA-Holder Class Null + FIRST EMD Serono/Merck KGaA MET Null

MET Two-NDA-Holder Class Null: Novartis (US/NJ) + Merck KGaA/EMD Serono (DE/MA) — Same Zero OEL

Capmatinib (CAS 1029712-80-8; attack #529; Novartis NDA 213591; May 6 2020) was the first MET inhibitor FDA-approved for METex14-skipping NSCLC, with MET IC50 ~0.13 nM. Tepotinib targets the same METex14 pathway with MET IC50 ~3 nM from a distinct triazolopyrimidine scaffold. Despite 23-fold potency difference and independent development programs on separate continents — Novartis (East Hanover NJ; Swiss parent) and Merck KGaA (Darmstadt Germany; EMD Serono Billerica MA US) — both compounds target the same CBL-Tyr1003 ubiquitin E3 ligase molecular mechanism (METex14 splice site removes juxtamembrane exon 14 → loss of Tyr1003 → Cbl cannot ubiquitinate MET → constitutive surface MET → HGF-independent activation). This cross-continental, cross-company class null mirrors patterns already established for CDK4/6 (Pfizer/Novartis/Lilly three-NDA null), KRASG12C (Amgen/BMS-Mirati two-NDA null), and FGFR (Incyte/Taiho/Janssen three-NDA null): the mechanism class, not the individual compound, determines EHS platform absence. Tepotinib's prior global approval in Japan (March 2020; Chugai Pharmaceutical; FIRST MET inhibitor approved anywhere) means Merck KGaA's EHS null pre-dates the US NDA by 11 months.
