Tisotumab vedotin-tftv (CAS 2098583-07-4; NIOSH HD Category 1) is the first tissue factor (TF; F3; CD142)-directed ADC with a vedotin (MMAE) warhead ever FDA approved, establishing the 143rd mechanism class in the Glyphward adversarial portfolio. Developed by Genmab (Copenhagen, Denmark; HuMax-TF antibody) and Pfizer/Seagen (vedotin linker-payload technology), tisotumab vedotin-tftv (HuMax-TF-ADC; Tivdak) consists of a fully human anti-TF IgG1 κ antibody (HuMax-TF; generated by transgenic mouse immunization) conjugated to MMAE (MW 717.9 g/mol; dolastatin 10 analog; β-tubulin vinca-site inhibitor) via MC-VC-PABC (maleimidocaproyl-valine-citrulline-p-aminobenzylcarbamate; cathepsin B-cleavable) cleavable linker (DAR ~4; MW ~155 kDa). TF (F3; coagulation factor III; chromosome 1p21.3; 263 amino acids; type I transmembrane glycoprotein) initiates coagulation via FVIIa binding (Kd ~10 pM) → TF-FVIIa complex activates FX and FIX; not expressed on vascular endothelium lumen (coagulation only on vessel wall disruption) but overexpressed in cervical cancer (~90%), NSCLC (~60-80%), and other solid tumors — providing ADC selectivity via internalization upon antibody binding. innovaTV 204 (NCT03438396) ORR 24% → BLA 761208 accelerated September 20 2021; innovaTV 301 OS HR 0.70 (p=0.0038) → full approval November 20 2024. No OEL exists for tisotumab vedotin-tftv in any EHS framework; no platform references TF fibronectin type II FVIIa-binding domain biology, PAR2 signaling via TF-FVIIa proteolysis, MC-VC-PABC Val-Cit cathepsin B linker chemistry, or MMAE β-tubulin vinca-site mechanism for this TF ADC class.

Tissue Factor Coagulation Initiator Biology and MMAE Vedotin ADC Chemistry: Structural Basis for TF-Directed MMAE Delivery in Cervical Cancer

Tissue factor (TF; F3; CD142; coagulation factor III; chromosome 1p21.3; 263 amino acids; MW ~47 kDa unglycosylated) is a type I transmembrane glycoprotein structurally featuring an N-terminal fibronectin type II-like extracellular domain (~150 residues; two fibronectin type II subdomains, D1 and D2; FVIIa serine protease binding interface: TF residues Arg135/Phe140/Lys165/Lys166 contact FVIIa EGF1-EGF2 domains via shape complementarity; TF-FVIIa Kd ~10 pM), an EGF-like structural subdomain (~60 residues; Cys49-Cys57 disulfide; scaffolding), a single-pass transmembrane domain, and a short cytoplasmic tail (19 residues; Ser253/Ser258 PKCα phosphorylation; PAR2 signaling via TF-FVIIa protease activation → G protein → MAPK/PI3K → proliferation/migration). TF physiological role: coagulation initiation upon vessel wall injury (TF expressed in adventitial cells/fibroblasts/astrocytes [subendothelial]; NOT on vascular endothelium lumen → coagulation activated only after disruption); TF-FVIIa complex activates FX → FXa (macromolecular extrinsic tenase with FVa) → prothrombinase → thrombin → fibrin clot; also activates FIX → FIXa (boosts intrinsic pathway). TF expression in cervical cancer (~90%; H-score >100 or ≥50% cells 2+/3+ IHC): correlates with VEGF, invasion, and poor prognosis; not associated with coagulopathy at tumor concentrations (endothelium inaccessibility maintained). Tisotumab vedotin-tftv ADC mechanism: HuMax-TF antibody binds TF extracellular domain → clathrin-mediated endocytosis (internalization T½ ~2-4 hr at 37°C) → lysosomal cathepsin B cleaves Val-Cit → self-immolation of PABC → free MMAE release → β-tubulin vinca-site binding → G2/M arrest → apoptosis; MMAE bystander effect (membrane-permeable) → kills adjacent TF-low cells. Ocular toxicity (conjunctival adverse events, keratopathy ~37%; corneal ulceration <5%) reflects TF expression on corneal epithelium — Genmab/Pfizer TF ADC on-target corneal toxicity distinct from MMAE peripheral neuropathy. No EHS platform references TF fibronectin type II FVIIa-binding extracellular domain structure, PAR2 TF-FVIIa oncogenic signaling, MC-VC-PABC Val-Cit self-immolative PABC chemistry, or corneal epithelial on-target TF expression for this TF ADC mechanism class.
