Definitions

  • Tissue factor plays an important role in these coagulation processes.
  • TF is a cell surface receptor for the serine protease factor VIIa (FVIIa).
  • FVIIa serine protease factor VIIa
  • the TF/FVIIa complex catalyzes conversion of the inactive protease factor X (FX) into the active protease factor Xa (FXa).
  • FXa and its co-factor FVa form the prothrombinase complex, which generates thrombin from prothrombin.
  • Thrombin converts soluble fibrinogen into insoluble strands of fibrin and catalyzes many other coagulation-related processes.
  • TF is over-expressed on multiple types of solid tumors.
  • TF/FVIIa signaling can support angiogenesis, tumor progression, and metastasis.
  • Increased TF expression can also induce inflammation and/or angiogenesis in many other diseases, including wet age-related macular degeneration (AMD) and diabetic retinopathy.
  • AMD wet age-related macular degeneration

  • a TF-positive head and neck cancer patient-derived xenograft model was generated in athymic nude mice (Envigo, Indianapolis, Ind.) to further evaluate the efficacy of the ADCs in vivo.
  • Tumors were passaged in stock animals and harvested for re-implantation.
  • Study animals were implanted unilaterally on the left flank with tumor fragments and were randomized to treatment group when tumors reached an average size of 150-200 mm 3 . Animals were treated with 5 mg/kg of the indicated ADC intraperitoneally (i.p.) once weekly for 2 weeks.
  • Body weight and tumor size assessments were performed bi-weekly. Animals were removed from study and euthanized once tumor size reached 1200 mm 3 or skin ulceration was evident.
  • FIG. 11 shows the tumor size of IgG1 ADC-treated and anti-TF ADC-treated groups in the head and neck cancer patient-derived xenograft model.
  • ADCs comprising anti-TF antibodies 25A and 43Ea conjugated to MC-vc-PAB-MMAE decreased the tumor size in the cancer patient-derived xenograft model compared to the IgG1 ADC-treated group.
  • pig TF Biacore-based measurements a given anti-TF antibody was captured by an anti-human IgG antibody covalently coupled to a CMS chip (GE Healthcare Bio-Sciences). Association between the anti-TF antibodies and a five-point three-fold titration of pig TF-His starting at 100 nM was measured for 180 to 240 sec. Subsequently, dissociation between the anti-TF antibody and TF-His was measured for 1800 sec. Kinetic data was analyzed and fitted globally using a 1:1 binding model. The K D values of the indicated TF antibodies measured by the Biacore-based experiments are shown in Table 40.
  • anti-hTF antibodies from groups 25 and 43, 25G9 and 43D8 exhibit binding activity and cross-reactivity to pig TF.
