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 population of allogeneic cytotoxic T lymphocytes (CTLs) specifically reactive to the herpes virus cytomegalovirus (CMV) with potential immunomodulating and antiviral activities. Upon immunoprophylactic adoptive cell therapy infusion with allogeneic cytomegalovirus-specific cytotoxic T lymphocytes, these CTLs may help reconstitute CMV-specific CTL responses in CMV-infected immunocompromised hosts after allogeneic hematopoietic stem cell transplant, thereby potentially preventing the occurrence of CMV viral disease or reducing the amount of antiviral drug therapy.

A population of activated, immortalized, interleukin-2 (IL-2)-dependent, cytotoxic natural killer (NK) cells with potential antitumor activity. Natural killer cells ZRx101 are derived from NK-92 cells, having been modified to target tumor-associated antigens (TAAs) upregulated in certain types of cancer. The NK-92 cell line was originally isolated from a patient with large granular lymphocytic (LGL) leukemia/lymphoma.

A population of allogeneic cytotoxic T lymphocytes (CTLs) specifically reactive to cytomegalovirus (CMV) and adenovirus (AdV) with potential antiviral activity. Allogeneic CMV/AdV-specific cytotoxic T lymphocytes are prepared by exposing donor-derived CTLs to a lethally irradiated Epstein-Barr virus-positive lymphoblastoid B cell line (EBV-LCL) that has been transduced with a clinical-grade adenoviral vector (Ad5f35CMVpp65) as a source of CMV and AdV antigens. Infusion of these CTLs into stem cell transplant recipients may prevent CMV and AdV viral disease.
Industry:Pharmaceutical
A population of a type of antigen-presenting cell (APC), the dendritic cell (DC), harvested from a patient and grown in vitro in the presence of tumor-associated antigens (TAAs) derived from the patient's tumor (a technique known as 'pulsing') and then injected back into the patient; autologous DCs so manipulated may stimulate a specific cell-mediated antitumoral cytotoxicity. DCs derived from a patient may also be fused with the patient's tumor cells in vitro to combine sustained tumor antigen expression with the antigen-presenting and immunostimulatory capacities of DCs; when injected back into the patient, these autologous DC-tumor cell hybrids (fusion cells) may stimulate an active antitumoral immune response.

A poorly soluble, ortho-naphthoquinone with potential antineoplastic and radiosensitizing activity. Beta-lapachone (b-lap) is bioactivated by NAD(P)H:quinone oxidoreductase-1 (NQO1), creating a futile oxidoreduction that generates high levels of superoxide. In turn, the highly reactive oxygen species (ROS) interact with DNA, thereby causing single-strand DNA breaks and calcium release from endoplasmic reticulum (ER) stores. Eventually, the extensive DNA damage causes hyperactivation of poly(ADP-ribose) polymerase-1 (PARP-1), an enzyme facilitating DNA repair, accompanied by rapid depletion of NAD+/ATP nucleotide levels. As a result, a caspase-independent and ER-stress induced mu-calpain-mediated cell death occurs in NQO1-overexpressing tumor cells. NQO1, a flavoprotein and two-electron oxidoreductase, is overexpressed in a variety of tumors.
Industry:Pharmaceutical
A poly-Toll-like receptor (TLR) agonist polyantigenic vaccine containing heat killed Mycobacterium indicus pranii (Mycobacterium w or Mw) with potential immunostimulating and antineoplastic activities. Upon administration, poly-TLR agonist polyantigenic vaccine activates a number of TLRs, which may result in macrophage and plasmacytoid dendritic cell (pDC) stimulation; secretion of interferon alpha; production of pro-inflammatory cytokines; upregulation of co-stimulatory molecules, enhanced T and B-cell stimulatory responses; T cell proliferation, and a Th1 immune response. TLRs are transmembrane receptors that recognize structurally conserved microbial molecules such as bacterial cell-surface lipopolysaccharides (LPS), lipoproteins, lipopeptides, lipoarabinomannan and flagellin, among others; immune responses stimulated by TLR activation may result in antineoplastic effects.

A polysulphonated naphthylurea with potential antineoplastic activity. Suramin blocks the binding of various growth factors, including insulin-like growth factor I (IGF-I), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and tumor growth factor-beta (TGF-beta), to their receptors, thereby inhibiting endothelial cell proliferation and migration. This agent also inhibits vascular endothelial growth factor (VEGF)- and basic fibroblast growth factor (bFGF)-induced angiogenesis; retroviral reverse transcriptase; uncoupling of G-proteins from receptors; topoisomerases; cellular folate transport; and steroidogenesis.
Industry:Pharmaceutical
A polypeptide quinoxaline antineoplastic antibiotic isolated from the bacterium Streptomyces echinatus. Echinomycin intercalates into DNA at two locations simultaneously in a sequence-specific fashion, thereby inhibiting DNA replication and RNA synthesis.

A polymeric prodrug of camptothecin (CPT) with potential antineoplastic activity. Polymeric camptothecin prodrug XMT-1001 consists of CPT conjugated to the 60-70 kDa, inert, bio-degradable, hydrophilic copolymer poly(1-hydroxymethylene hydroxymethyl formal) (PHF). Through a dual-phase, non-enzymatic release mechanism, CPT is first released in plasma from XMT-1001 as the lipophilic prodrugs CPT-SI (a succinimidoglycinate derivative) and CPT-SA (a succinamidoyl glycinate derivative), which are then hydrolyzed within tissues to release the lactone form of CPT. CPT inhibits the catalytic activity of DNA topoisomerase I, thereby inhibiting DNA replication and inducing apoptosis. This agent may exhibit a more favorable pharmacokinetic profile than other agents in the same class.
Industry:Pharmaceutical
A polymeric prodrug consisting of the fumagillol-derived small molecule XMT-1191 tethered to the hydrophilic, biodegradable70 kDa polymer poly(1- hydroxymethylethylene hydroxymethylformal) (PHF) with potential antiangiogenic and antineoplastic activities. Upon administration, fumagillin-derived polymer conjugate XMT-1107 releases XMT-1191, which may inhibit angiogenesis through the irreversible inhibition of the methionine aminopeptidase 2 (METAP2); although the exact mechanism of action has yet to be fully elucidated, this agent appears to induce cell cycle arrest in endothelial cells, inhibiting their proliferation and migration. Compared to an unconjugated fumagillin analog, XMT-1107 exhibits improved solubility and an extended half life due to its PHF backbone. METAP2, a member of the methionyl aminopeptidase family, binds two cobalt or manganese ions and protects the alpha subunit of eukaryotic initiation factor 2 (EIF2) from inhibitory phosphorylation by removing the amino-terminal methionine residue from nascent protein; this aminopeptidase may be overexpressed in a variety of tumor cell types.
