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 peptide-based cancer vaccine composed of amino acids 264 to 272 of the wild-type protein encoded by the P53 gene. P53 peptide vaccine may elicit an HLA-A2. 1-restricted cytotoxic T lymphocyte immune response against tumor cells that overexpress p53 protein.
Industry:Pharmaceutical
A peptide vaccine, containing human tumor-associated epithelial mucin (MUC1) conjugated with keyhole limpet hemocyanin (KLH), with potential antineoplastic activity. Vaccination with MUC1-KLH conjugate vaccine may stimulate humoral and cytotoxic T-lymphocyte (CTL) responses against tumor cells expressing the MUC1 antigen. In this vaccine, MUC1 antigen is conjugated with KLH, an immunostimulant and a hapten carrier, to enhance immune recognition. MUC1 antigen, a membrane-bound glycoprotein expressed by most glandular and ductal epithelial cells, is overexpressed in an aberrant or deglycosylated form in various cancers such as those of the breast, prostate, and ovary.
Industry:Pharmaceutical
A peptide vaccine preparation, containing recombinant human epidermal growth factor (rEGF) linked to the Neisseria meningitidis-derived recombinant immunogenic carrier protein P64k (rP64k) and mixed with the immunoadjuvant Montanide ISA 51, with potential active immunotherapy activity. Recombinant human EGF-rP64K/Montanide ISA 51 vaccine may trigger a humoral immune response against vaccine rEGF and rP64K and, so, against endogenous EGF. Antibody-mediated inhibition of endogenous EGF binding to its receptor, epithelial growth factor receptor (EGFR), may result in the inhibition of tumor cell proliferation.
Industry:Pharmaceutical
A peptide vaccine derived from the synthetic peptide pyroEHWSYGLRPG, corresponding to amino acids 22-31 of mouse gonadotropin releasing hormone (GnRH), with potential immunocastration activity. PEP223 is dimerized and contains a D-lysine (k) substitution at position 6 (pyroEHWSYkLRPG) to increase its immunogenicity. Anti-GnRH vaccine PEP223 may stimulate the immune system to mount a cytotoxic T-lymphocyte (CTL) response against GnRH, neutralizing its activity. In turn, testosterone production and tumor cell growth may be inhibited in testosterone-sensitive tumors.
Industry:Pharmaceutical
A peptide vaccine containing the human tumor-associated antigen epithelial mucin (MUC1 antigen) conjugated with keyhole limpet hemocyanin (KLH) and combined with the nonspecific immunoadjuvant QS21 with potential antineoplastic activity. MUC1 antigen is linked with KLH, an immunostimulant and a hapten carrier, in order to enhance immune recognition; the co-administration of saponin-derived QS21 potentially amplifies the total immune response to the MUC1 antigen. Administration of MUC1-KLH vaccine/QS21 may result in both the production of antitumor antibodies and the stimulation of a cytotoxic T-lymphocyte (CTL) response against tumor cells expressing the MUC1 antigen. MUC1 antigen, a membrane-bound glycoprotein expressed by most glandular and ductal epithelial cells, is overexpressed as an aberrant or deglycosylated form in various cancers such as breast, prostate and ovarian cancers.
Industry:Pharmaceutical
A peptide vaccine containing an HLA-A*2402-restricted epitope of vascular endothelial growth factor receptor 1 (VEGFR1 or Flt-1) with potential immunostimulating, antiangiogenic, and antineoplastic activities. Upon vaccination, VEGFR1-1084 peptide vaccine may stimulate a cytotoxic T lymphocyte (CTL) response against VEGFR1-expressing endothelial cells of the tumor microvasculature, which may inhibit tumor angiogenesis and tumor cell proliferation. VEGFR1, a receptor tyrosine kinase, may be overexpressed on endothelial cells of the tumor microvasculature and is associated with tumor cell proliferation, invasion and tumor angiogenesis. HLA-A*2402 is an MHC class I molecule that presents antigenic peptides to CD8+ T cells; epitope design restricted to epitopes that bind most efficiently to HLA-A*2402 may improve antigenicity.

A peptide vaccine containing an HLA-A*2402-restricted epitope of vascular endothelial growth factor receptor (VEGFR) 2 with potential immunostimulatory and antineoplastic activities. Upon administration, VEGFR2-169 peptide vaccine may stimulate a cytotoxic T lymphocyte (CTL) response against VEGFR2-expressing tumor cells. VEGFR2, a receptor tyrosine kinase, is overexpressed by a variety of tumor types; overexpression is associated with tumor cell proliferation and tumor angiogenesis. HLA-A*2402 is an MHC class I molecule that presents antigenic peptides to CD8+ T cells; epitope design restricted to epitopes that bind most efficiently to HLA-A*2402 may improve antigenic peptide immunogenicity.
Industry:Pharmaceutical
A peptide vaccine containing a human Wilms tumor 1 (WT-1) protein-derived epitope with potential antineoplastic activity. Vaccination with the WT-1 analog peptide vaccine may induce a cytotoxic T-lymphocyte (CTL) response against WT-1 expressing cells, resulting in tumor cell lysis and inhibition of tumor cell proliferation. WT-1, a zinc finger transcription factor, is overexpressed in most types of leukemia and in some solid cancers.
Industry:Pharmaceutical
A peptide vaccine containing a 15-mer peptide (DLAQMFFCFKELEGW), with C to M alteration at amino acid position 57, derived from the anti-apoptosis protein survivin, and conjugated with keyhole limpet hemocyanin (KLH), with potential immunopotentiating and antineoplastic activities. Upon subcutaneous administration of SVN53-67/M57-KLH peptide vaccine, this peptide is able to bind both HMC class I and II molecules and may activate the immune system to mount a cytotoxic T-lymphocyte (CTL) as well as a T-helper cell response against survivin-expressing cancer cells. This may result in decreased tumor cell proliferation and ultimately tumor cell death. Survivin, a member of the inhibitor of apoptosis (IAP) family, expressed during embryonic development while absent in most normal adult cells, is upregulated in a variety of human cancers; its expression in tumors is associated with a more aggressive phenotype, decreased survival, and increased resistance to chemotherapy. KLH may enhance immune recognition and may promote an enhanced response. As SVN53-67 is weakly immunogenic in humans, the M57 alteration may lead to greater affinity towards HLA-A*0201 and thus an enhanced antitumor immune response.
Industry:Pharmaceutical
A peptide vaccine consisting of the whole or partial beta subunit of human chorionic gonadotrophin hormone (hCG), linked to an adjuvant carrier of bacterial or viral origin, with anti-fertility activity. Anti-human chorionic gonadotropin vaccine blocks the activity of hCG which is naturally produced by the trophectoderm of the pre-implantation embryo within a few days of fertilization. HCG is required for the maintenance of the corpus luteum in the ovary thus ensuring its continued production of progesterone, which is required for the successful completion of implantation of the blastocyst. Without progesterone, the corpus luteum regresses, and menstruation is initiated.
