Company Profile:
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 narrow-spectrum, 18-membered macrolide antibiotic isolated from the actinomycete Dactylosporangium aurantiacum subsp. Hamdenensis with potential antibacterial activity. Although the exact mechanism of action has yet to be fully elucidated, fidaxomicin may bind to and inhibit bacterial DNA-dependent RNA polymerase, thereby inhibiting the initiation of bacterial RNA synthesis. When orally administered, this agent is minimally absorbed into the systemic circulation, acting locally in the gastrointestinal tract. Tiacumicin B appears to be active against pathogenic Gram-positive bacteria, such as clostridia, enterococci, and staphylococci, but does not appear to be active against other beneficial intestinal bacteria.

A nanoparticle-based prodrug formulation consisting of polymeric micelles incorporating the inorganic platinum agent cisplatin with potential antineoplastic activity. In micellar nanoparticle-encapsulated cisplatin NC-6004, cisplatin forms a polymer-metal complex with hydrophilic polyethylene glycol poly(glutamic acid) block copolymers by attaching to the micelle inner core consisting of the hydrophobic polymer polyamino acid. Upon cell entry and release from the polymer-metal complex, cisplatin forms highly reactive, charged platinum complexes that bind to nucleophilic groups such as GC-rich sites in DNA, inducing intrastrand and interstrand DNA cross-linking, DNA-protein cross-linking and, subsequently, tumor cell apoptosis and growth inhibition. Due to the hydrophilic nature of polyethylene glycol, this formulation increases the water-solubility of cisplatin and decreases the nephrotoxicity and neurotoxicity associated with the administration of cisplatin alone.

A nanoparticle formulation containing N-glutaryl phosphatidylethanolamine (NGPE)-liposomes encapsulating oxaliplatin and conjugated to the human transferrin (Tf) ligand, with potential antineoplastic activity. Upon infusion of oxaliplatin-encapsulated transferrin-conjugated NGPE liposomes, the transferrin moiety targets and binds to the Tf receptor, which is overexpressed on a variety of human cancer cells. Upon binding and internalization, oxaliplatin is released and its active derivatives alkylate macromolecules, forming both inter- and intra-strand platinum-DNA crosslinks, resulting in an inhibition of DNA replication and transcription. By extending the circulation time and specifically targeting transferrin receptors, this formulation may improve the efficacy and safety of oxaliplatin therapy, compared to administration of oxaliplatin alone. NGPE, a reactive phospholipid, is used as a linker to attach the Tf ligand, to the liposome.

A nanoparticle albumin-bound formulation of the taxane docetaxel with antineoplastic activity. Docetaxel is a semi-synthetic, second-generation taxane derived from a compound found in the European yew tree Taxus baccata. Docetaxel binds to and stabilizes tubulin, thereby inhibiting microtubule disassembly which results in cell-cycle arrest at the G2/M phase and cell death. This agent also inhibits pro-angiogenic factors such as vascular endothelial growth factor (VEGF) and displays immunomodulatory and pro-inflammatory properties by inducing various mediators of the inflammatory response. In nanoparticle albumin-bound docetaxel ABI-008 docetaxel is solubilized without the use of the nonionic solubilizer Cremophor ELP, permitting the administration of larger doses of docetaxel while avoiding Cremophor ELP-associated toxicity.

A murine monoclonal IgG2a antibody to tumor-associated epithelial cell adhesion molecule (EpCAM, or 17-1A) antigen. Edrecolomab attaches to EpCAM, a human cell surface glycoprotein that is found on normal epithelial cells and some tumor cells, such as those of colon and breast carcinomas. Upon binding, this agent recruits the body's immune effector cells, which may exhibit antitumor cytotoxicity.
Industry:Pharmaceutical
A murine monoclonal antibody with two antigen-recognition sites: one for CD3, an antigen expressed on mature T cells, and one for HER-2-neu, a tumor-associated antigen that promotes tumor growth. Ertumaxomab attaches to CD3-expressing T cells and HER-2-neu-expressing tumor cells, selectively cross-linking tumor and immunologic cells which results in the recruitment of cytotoxic T cells to the T cell/tumor cell aggregate.
Industry:Pharmaceutical
A murine monoclonal antibody with potential antineoplastic activity. Monoclonal antibody HeFi-1 binds to CD30, a cell surface antigen found on mitogen-activated B-cells and T-cells, and Reed-Sternberg cells. Monoclonal antibody HeFi-1 has been shown to arrest tumor growth and prevent metastasis in animal models.
Industry:Pharmaceutical
A murine monoclonal antibody directed against the ganglioside GD2 with potential antineoplastic activity. Monoclonal antibody 14G2A binds to the ganglioside GD2 and induces antibody-dependent cell mediated cytotoxicity and complement-dependent cytotoxicity against GD2-expressing tumor cells. GD2 is overexpressed in malignant melanoma, neuroblastoma, osteosarcoma, and small cell carcinoma of the lung.
Industry:Pharmaceutical
A murine monoclonal antibody directed against the cell-surface, tumor-associated antigen ganglioside GD2. Vaccination with monoclonal antibody 3F8 may stimulate a host cytotoxic immune response against tumors that express ganglioside GD2.
Industry:Pharmaceutical
A murine monoclonal antibody directed against the beta subunit of the interleukin-2 receptor (IL-2R), expressed on resting T-lymphocytes, natural killer (NK) cells, and some leukemic cell types. Monoclonal antibody Mik-beta-1 prevents the binding of IL-2 to IL-2R beta, thereby inhibiting the IL-2-mediated proliferation and activation of T-cells.
