Antibodies are important therapeutic agents for cancer. Recently, it has become clear that antibodies possess several clinically relevant mechanisms of action. Many clinically useful antibodies can manipulate tumour-related signalling. In addition, antibodies exhibit various immunomodulatory properties and, by directly activating or inhibiting molecules of(More)
The purpose of the National Cancer Institute pilot project to prioritize cancer antigens was to develop a well-vetted, priority-ranked list of cancer vaccine target antigens based on predefined and preweighted objective criteria. An additional aim was for the National Cancer Institute to test a new approach for prioritizing translational research(More)
The most significant recent advances in the application of monoclonal antibodies (mAbs) to oncology have been the introduction and approval of bevacizumab (Avastin), an anti–vascular endothelial growth factor antibody, and of cetuximab (Erbitux), an anti–epidermal growth factor antibody. In combination with standard chemotherapy regimens, bevacizumab(More)
2B1 is a bispecific murine monoclonal antibody (BsMAb) with specificity for the c-erbB-2 and Fc gamma RIII extracellular domains. This BsMAb promotes the targeted lysis of malignant cells overexpressing the c-erbB-2 gene product of the HER2/neu proto-oncogene by human natural killer cells and mononuclear phagocytes expressing the Fc gamma RIII A isoform. In(More)
PURPOSE A phase II clinical trial was conducted to evaluate the feasibility and tolerability of a prime/boost vaccine strategy using vaccinia virus and fowlpox virus expressing human prostate-specific antigen (PSA) in patients with biochemical progression after local therapy for prostate cancer. The induction of PSA-specific immunity was also evaluated. (More)
PURPOSE This phase 1 study evaluated the safety, pharmacokinetics, and activity of panitumumab, a fully human, IgG2 monoclonal antibody that targets the epidermal growth factor receptor in patients with previously treated epidermal growth factor receptor-expressing advanced solid tumors. EXPERIMENTAL DESIGN Sequential cohorts were enrolled to receive four(More)
Tumor-associated fibroblasts are functionally and phenotypically distinct from normal fibroblasts that are not in the tumor microenvironment. Fibroblast activation protein is a 95 kDa cell surface glycoprotein expressed by tumor stromal fibroblasts, and has been shown to have dipeptidyl peptidase and collagenase activity. Site-directed mutagenesis at the(More)
Cancers of the breast and other tissues arise from aberrant decision-making by cells regarding their survival or death, proliferation or quiescence, damage repair or bypass. These decisions are made by molecular signalling networks that process information from outside and from within the breast cancer cell and initiate responses that determine the cell's(More)
OBJECTIVES Given the extensive desmoplastic response associated with pancreatic adenocarcinoma, we hypothesized that the stromal protein fibroblast activation protein (FAP) would be highly expressed and associated with the presence of fibrosis and other clinical features. METHODS Paraffin-embedded pancreatic adenocarcinomas that were resected with(More)
The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein, with an extracellular ligand-binding domain and intracellular tyrosine kinase domain. Ligand binding induces EGFR dimerization and autophosphorylation on several tyrosine residues in the intracellular domain, leading to mitogenic signal transduction. EGFR overexpression correlates(More)
