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 water-soluble, folate-receptor-targeted conjugate of folate and the vinca alkaloid desacetylvinblastine monohydrazide (DAVLBH) with potential antineoplastic activity. The folate moiety of folate-vinca alkaloid conjugate EC145 binds to folic acid receptors on the tumor cell surface and the agent is internalized via folate receptor-mediated endocytosis, delivering the tubulin-binding DAVLBH moiety directly into the tumor cell; DAVLBH binding to tubulin results in the disruption of microtubule assembly-disassembly dynamics, cell cycle arrest, and tumor cell apoptosis. Folic acid receptors are frequently upregulated on the surfaces of many tumor cell types. DAVLBH is a derivative of the natural product vinblastine.

A water-soluble, positively charged fusion protein consisting of a luteinizing hormone releasing hormone (LHRH) receptor-targeting ligand conjugated to the membrane-disrupting peptide CLIP 71 with membrane-disrupting and potential antineoplastic activities. The LHRH ligand moiety of membrane-disrupting peptide EP-100 specifically binds to LHRH receptors, which are upregulated on a variety of human cancer cell types. Subsequently, the positively charged CLIP 71 moiety of this agent interacts with the negatively charged membrane on the cancer cell surface, which may result in cell membrane disruption and cell lysis.

A water-soluble, semi-synthetic derivative of the sesquiterpine lactone artemisinin with anti-malarial, anti-shistosomiasis, antiviral, and potential anti-neoplastic activities. Upon hydrolysis of artesunate’s active endoperoxide bridge moiety by liberated heme in parasite-infected red blood cells, reactive oxygen species and carbon-centered radicals form, which have been shown to damage and kill parasitic organisms. Additionally, in vitro studies demonstrate that this agent induces DNA breakage in a dose-dependent manner. Artesunate has also been shown to stimulate cell differentiation, arrest the cell cycle in the G1 and G2/M phases, inhibit cell proliferation, and induce apoptosis through mitochondrial and caspase signaling pathways. Artemisinin is isolated form the plant Artemisia annua.

A water-soluble, synthetic aziridinylbenzoquinone with potential antineoplastic activity. Bioactivation of aziridinylbenzoquinone RH1 occurs through the two-electron reduction of the quinone to the hydroquinone by the two-electron quinone reductase DT-diaphorase (DTD). The resultant hydroquinone selectively alkylates and cross-links DNA at the 5'-GNC-3' sequence, inihibiting DNA replication, inducing apoptosis, and inhibiting tumor cell proliferation. DTD is over-expressed in many tumors relative to normal tissue, including lung, colon, breast and liver tumors.
Industry:Pharmaceutical
A water-soluble, synthetic small molecule with potential antineoplastic activity. Aurora Kinase Inhibitor AS703569 selectively binds to and inhibits aurora kinases (AKs), a family of serine-threonine kinases which are important regulators of cell division and proliferation, and which are overexpressed in certain types of cancer. Inhibition of aurora kinases inhibits cell division and proliferation and induces apoptosis in tumor cells overexpressing AKs.
Industry:Pharmaceutical
A whole cell vaccine comprised of irradiated allogeneic renal cell carcinoma (RCC) with potential immunostimulating and antineoplastic activities. Allogeneic renal cell carcinoma vaccine MGN1601 contains two active ingredients: 1) genetically modified allogeneic RCC cells that are transiently transfected with four different MIDGE (Minimalistic Immunogenically Defined Gene Expression) vectors encoding IL-7, GM-CSF, CD80 and CD154 and 2) the synthetic DNA-based immunomodulator dSLIM-30L1, a TLR9 agonist. Vaccination results in expression of IL-7, GM-CSF, CD80 and CD154, which all contribute to the activation or enhancement of immune responses. Furthermore, administration of this RCC vaccine may elicit a cytotoxic T lymphocyte (CTL) response against similar host tumor cells, resulting in decreased tumor growth. TLR9 is a member of the TLR family, which plays a fundamental role in pathogen recognition and activation of innate immunity.

A whole cell vaccine comprised of irradiated allogenic pancreatic tumor cells transfected with a plasmid DNA encoding human sargramostim (GM-CSF). Vaccination results in expression of GM-CSF, which induces proliferation and differentiation hematopoietic lineage cells as well as stimulating macrophage and dendritic cell functions in antigen presentation and antitumor cell-mediated immunity. Furthermore, administration of this pancreatic tumor cell vaccine may elicit a cytotoxic T lymphocyte (CTL) response against similar host tumor cells, resulting in decreased tumor growth.
Industry:Pharmaceutical
A whole cell vaccine expressing human granulocyte macrophage-colony stimulating factor (GM-CSF) with potential antineoplastic activity. Tumor cells from prostate cancer patients are harvested and then genetically modified to secrete GM-CSF, an immune stimulatory growth factor that plays a key role in stimulating the body's immune responses against tumor cells. Because the vaccine is derived from allogeneic cells, it has demonstrated a favorable side effect profile than other approaches of delivering long-lasting GM-CSF.

A whole, heat-killed, recombinant Saccharomyces cerevisiae yeast-based vaccine genetically altered to express the carcinoembryonic antigen (CEA) peptide 610D with potential immunostimulating and antineoplastic activities. Upon administration, recombinant Saccharomyces cerevisia-CEA(610D) vaccine GI-6207 may stimulate a host cytotoxic T-lymphocyte (CTL) response against CEA-expressing tumor cells, which may result in tumor cell lysis. CEA, a tumor associated antigen, is overexpressed on a wide variety of human cancer cells including colorectal, gastric, lung, breast and pancreatic cancer cells. CEA 610D encodes for 9 amino acids (605-613) in which aspartate is substituted for asparagine at position 610 (610D) in order to strengthen the induction of the CTL response against CEA-expressing tumor cells.
Industry:Pharmaceutical
A whole-cell cancer vaccine, containing human acute myeloid leukemic (AML) blasts that have been genetically engineered to express a B7. 1/IIL-2 fusion protein encoded by a self-inactivating lentiviral vector (LV), with potential antineoplastic and immunomodulating activities. Upon administration, LV. IL-2/B7. 1-transduced AML blast vaccine may stimulate a host cytotoxic T lymphocyte (CTL) response against AML cells. The single fusion protein encoded by the LV is postsynthetically cleaved to produce biologically active membrane-anchored B7. 1 and secreted IL-2 in AML blasts; combined expression of IL-2 and the co-stimulatory molecule B7. 1 by AML blasts may increase stimulation of both allogeneic and autologous cytotoxic T cells.
