The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A cancer vaccine comprised of autologous dendritic cells pulsed with synthetic glioma-associated antigen (GAA) peptides with potential antineoplastic activity. Upon administration, this vaccine may stimulate anti-tumoral cytotoxic T lymphocyte (CTL) and antibody responses against GAA peptide-expressing glioma cells, resulting in tumor cell lysis.
Industry:Pharmaceutical
A cancer vaccine comprised of autologous dendritic cells (DCs) that have been transduced ex vivo with an adenoviral vector containing the CCL21 gene with potential immunostimulatory and antineoplastic activities. Upon intratumoral administration, autologous dendritic cell-adenovirus CCL21 vaccine expresses the chemokine CCL21, which may induce an antitumoral cytotoxic immune response in the tumor microenvironment. CCL21 (chemokine (C-C motif) ligand 21) has been shown to attract antigen presenting cells (APCs), like leukocytes and DCs, and natural killer (NK) cells and their T-cell effectors to induce a cytotoxic immune response.
Industry:Pharmaceutical
A cancer vaccine comprised of a synthetic peptide with an amino acid sequence corresponding to positions 154-163 of the amino acid sequence for prostate-specific antigen (PSA) with a leucine substitution at position 155. Upon administration, PSA:154-163(155L) peptide vaccine may elicit a cytotoxic T-cell response against tumor cells that express PSA.
Industry:Pharmaceutical
A cancer vaccine comprised of autologous dendritic cells (DCs) pulsed with the marine sponge glycolipid alpha-galactosylceramide (alpha-GalCer) with potential immunostimulatory and antimetastatic activities. Upon administration, alpha-galactosylceramide-pulsed autologous dendritic cells may result in the activation and proliferation of a subset of endogenous natural killer T ( NKT) cells, B cells, and CD4+ and CD8+ T cells, and the production of interferon-gamma and interleukin-12; these cascade events may result in a T helper-1 cell-biased proinflammatory antitumor immune response. The NKT cell ligand alpha-GalCer was originally isolated from the marine sponge Agelas mauritianusis.
Industry:Pharmaceutical
A cancer vaccine comprised of a synthetic peptide derived from the mucin 1 (MUC1) antigen with potential antineoplastic activity. Upon administration, MUC1 peptide vaccine may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells positive for the MUC1 antigen, resulting in decreased tumor growth. Overexpressed on many tumor cells, MUC1 antigen, a mammary-type apomucin, is a high-molecular-weight transmembrane glycoprotein.
Industry:Pharmaceutical
A cancer vaccine comprised of a recombinant fowlpox virus vector encoding TRICOM. TRICOM is comprised of three co-stimulatory molecule transgenes (B7-1, ICAM-1 and LFA-3) that may enhance antigen presentation and activate cytotoxic T-cells. Fowlpox virus is an attractive vector because its genome is easy to manipulate and it is replication incompetent in mammalian cells.
Industry:Pharmaceutical
A cancer vaccine comprised of a recombinant modified vaccinia Ankara (MVA) viral vector encoding the suicide gene FCU1with potential antineoplastic activity. FCU1 is a bifunctional yeast cytosine deaminase (CD) / uracil phosphoribosyltransferase (UPRT) fusion gene. Upon intratumoral administration, MVA-FCU1 TG4023 enters tumor cells where FCU1 is expressed. Subsequently, the noncytotoxic prodrug 5-fluorocytosine (5-FC) is administered systemically and is deaminated by CD in FCU1- transduced tumor cells into 5-fluorouracil (5-FU), which is then directly metabolized to 5-fluoro-uridine monophosphate (5-FUMP) by UPRT; 5-FUMP may then be further transformed to 5-fluoro-deoxyuridine monophosphate (5-FdUMP), an irreversible inhibitor of thymidylate synthase and, so, DNA synthesis through deprivation of deoxythymidine triphosphate (dTTP). 5-FU and its active metabolites may then selectively kill tumor cells, avoiding toxicity in nonmalignant cells. The MVA viral vector, derived from the replication-competent strain Ankara, is a highly attenuated, replication-defective vaccinia strain incapable of virion assembly.
Industry:Pharmaceutical
A cancer vaccine comprised of a recombinant fowlpox virus vector encoding the melanoma antigen glycoprotein 100 (gp 100) with potential antineoplastic activity. The expression of gp100 may generate a cellular immune response to melanoma cells; this effect is enhanced by the co-administration of interleukin 2 (IL-2).
Industry:Pharmaceutical
A cancer vaccine comprised of a recombinant fowlpox virus vector encoding the carcinoembryonic antigen (CEA) and a TRIad of COstimulatory Molecules (B7-1, ICAM-1 and LFA-3) (TRICOM). This agent may enhance CEA presentation to antigen presenting cells (APC) and activate cytotoxic T-cells against CEA-expressing tumors.
Industry:Pharmaceutical
A cancer vaccine comprised of a recombinant fowlpox virus vector encoding the stimulatory molecule transgene B7-1. Recombinant fowlpox-B7. 1 (rF-B7. 1) vaccine may enhance antigen presentation and activate antitumoral cytotoxic T-cells.
