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 proprietary preparation of polymeric nanoparticles containing the second-generation taxane docetaxel, targeted to prostate-specific membrane antigen (PSMA), with antineoplastic activity. PSMA-targeted docetaxel nanoparticles BIND-014 carry docetaxel within a matrix of polylactic acid covered with a coating of polyethylene glycol; embedded on the surface of the polyethylene glycol coating are ligands targeted to PSMA. BIND-014 allows gradual release of docetaxel upon degradation of the polylactic acid, and the PEG encapsulation escapes the host immune response while PSMA ligands on the surface restrict the cytotoxic effect to PSMA-expressing cells. Docetaxel binds to and stabilizes the beta-tubulin subunit, thereby inhibiting microtubule disassembly which results in cell-cycle arrest at the G2/M phase and cell death. PSMA is a cell-surface antigen that is abundantly present on the surface of cancer cells and on the neovasculature that feeds a wide variety of tumor types.

A proprietary preparation of natural human interferon alpha (IFN alpha) with potential immunomodulatory and antineoplastic activities. Natural human interferon alpha OPC-18 binds to cell-surface IFN alpha receptors (IFNARs), resulting in the transcription and translation of genes whose products mediate antiviral, antiproliferative, and immune-modulating effects. IFN alpha is a type I interferon produced by peripheral blood leukocytes or lymphoblastoid cells when exposed to live or inactivated virus, double-stranded RNA, or bacterial products and is the primary interferon produced by virus-induced leukocyte cultures. In addition to its pronounced antiviral activity, it activates NK cells.
Industry:Pharmaceutical
A proprietary preparation of mycobacterial DNA oligonucleotides embedded in mycobacterial cell wall fragments derived from cultures of Mycobacterium phlei, with potential immunomodulatory and antineoplastic activities. DNA oligonucleotides in the mycobacterial cell wall-DNA complex (MCC) induce apoptosis by increasing BAX protein levels, releasing cytochrome C from mitochondria, and activating caspase-3 and -7, which results in the cleavage of poly (ADP-ribose) polymerase and the release of nuclear matrix proteins. In addition to its pro-apoptotic effect, MCC activates monocytes and macrophages to produce various cytokines, including interleukin 6 (IL-6), IL-8, IL-12, IL-18, and tumor necrosis factor alpha (TNF-a). This results in the activation of natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) and interferon gamma (IFN-gamma) synthesis.
Industry:Pharmaceutical
A proprietary orally bioavailable inhibitor of the M1 family of aminopeptidases with potential antineoplastic activity. Tosedostat is converted intracellularly into a poorly membrane-permeable active metabolite (CHR-79888) which inhibits the M1 family of aminopeptidases, particularly puromycin-sensitive aminopeptidase (PuSA), and leukotriene A4 (LTA4) hydrolase; inhibition of these aminopeptidases in tumor cells may result in amino acid deprivation, inhibition of protein synthesis due to a decrease in the intracellular free amino acid pool, an increase in the level of the proapoptotic protein Noxa, and cell death. Noxa is a member of the BH3 (Bcl-2 homology 3)-only subgroup of the proapoptotic Bcl-2 (B-cell CLL/lymphoma 2) protein family.
Industry:Pharmaceutical
A proprietary oral formulation of D-methionine with antioxidant and antimucositis activities. D-methionine formulation MRX-1024 may selectively protect the oral mucosa from the toxic effects of chemotherapy and radiation therapy without compromising antitumor activity. D-methionine may be converted into the L- isomer in vivo, particlualry in instances of L-methionine deprivation; both isomers have antioxidant activity which may be due, in part, to their sulfur moieties and chelating properties. L-methionine, an essential amino acid, also may help to maintain the ratio of reduced glutathione to oxidized glutathione in cells undergoing oxidative stress and may provide a source of L-cysteine for glutathione synthesis.
Industry:Pharmaceutical
A proprietary multiherbal topical cream based on Chinese herbal medicine with potential antineoplastic, antiviral, antibacterial and immunostimulatory activities. Arnebia Indigo Jade Pearl topical cream contains 12 ingredients including 9 herbs infused in sesame oil, with an additional three powdered ingredients and beeswax added to the infused oil to create the salve. The purported mechanism(s) of action is unclear due to the complexity of the herbal mixture.
Industry:Pharmaceutical
A proprietary oil-in-water emulsion specifically designed for combining protein preparations used in vaccines. SB-AS02B adjuvant contains monophosphoryl lipid A and QS21, a saponin extracted from the South American tree Quillaja saponaria Molina. This agent may be used for formulating cancer-specific vaccine preparations such as those containing MAGE-3 melanoma protein.
Industry:Pharmaceutical
A proprietary fucose-free monoclonal antibody directed against human heparin-binding EGF-like growth factor (HBEGF) with potential antineoplastic activity. Anti-HB-EGF monoclonal antibody KHK2866 binds to HBEGF, thereby blocking its binding to the EGF receptors. This prevents EGF receptor activation and the subsequent induction of cell growth signaling. HBEGF is mitogenic for fibroblasts and smooth muscle and may be involved in macrophage-mediated cellular proliferation. The fucose-free monoclonal antibodies enhance antigen dependent cellular cytotoxicity (ADCC), and increase binding affinity to the Fc receptor to overcome genetic polymorphism.
Industry:Pharmaceutical
A proprietary formulation of resveratrol, a polyphenolic phytoalexin derived from grapes and other food products with potential antioxidant, anti-obesity, antidiabetic and chemopreventive activities. Resveratrol may activate sirtuin subtype 1 (SIRT-1). SIRT1 activation has been reported to inhibit tumorigenesis and tumor cell proliferation. SIRT-1 is a member of the silent information regulator 2 (SIR2) (or sirtuin) family of enzymes that plays an important role in mitochondrial activity and acts as a protein deacetylase. SIRT1 appears to be involved in the regulation of numerous transcription factors such as Nf-kB and p53.
Industry:Pharmaceutical
A proprietary DNA-based cancer vaccine that encodes a melanoma antigen tyrosinase-related protein 2 (TRP2) cytotoxic T-lymphocyte (CTL) epitope and a modified monoclonal antibody, a chimera of human IgG1/murine IgG2a with T cell mimotopes expressed within the complementarity-determining regions (CDR) of the antibodies, with potential immunostimulating and antineoplastic activities. Upon intramuscular injection and electroporation, melanoma TRP2 CTL epitope vaccine SCIB1 expresses the modified antibody. Subsequently, the Fc component of the engineered antibody targets and binds to the CD64 receptor on the dendritic cells (DCs); upon processing by DCs, the cellular immune system may be activated to induce helper T-cell and CTL immune responses against tumor cells expressing the TRP2 antigen.
