Label	Id	Description
Cyclophosphamide/Doxorubicin/Etoposide/Prednisone/Vincristine/R-Verapamil	NCIT_C29400
Dexverapamil	NCIT_C1563	[The R-enantiomer of the calcium channel blocker verapamil. Dexverapamil competitively inhibits the multidrug resistance efflux pump P-glycoprotein (MDR-1), thereby potentially increasing the effectiveness of a wide range of antineoplastic drugs which are inactivated by MDR-1 mechanisms. This agent exhibits decreased calcium antagonistic activity and toxicity compared to racemic verapamil. (NCI04)]
Cyclophosphamide	NCIT_C405	[A synthetic alkylating agent chemically related to the nitrogen mustards with antineoplastic and immunosuppressive activities. In the liver, cyclophosphamide is converted to the active metabolites aldophosphamide and phosphoramide mustard, which bind to DNA, thereby inhibiting DNA replication and initiating cell death.]
Vincristine	NCIT_C933	[A natural alkaloid isolated from the plant Vinca rosea Linn. Vincristine binds irreversibly to microtubules and spindle proteins in S phase of the cell cycle and interferes with the formation of the mitotic spindle, thereby arresting tumor cells in metaphase. This agent also depolymerizes microtubules and may also interfere with amino acid, cyclic AMP, and glutathione metabolism; calmodulin-dependent Ca++ -transport ATPase activity; cellular respiration; and nucleic acid and lipid biosynthesis. (NCI04)]
Anti-TGF-beta Monoclonal Antibody NIS793	NCIT_C132250	[A monoclonal antibody directed against human transforming growth factor beta (TGF-beta), with potential antineoplastic activity. Anti-TGF-beta monoclonal antibody NIS793 specifically targets and binds to TGF-beta, thereby preventing the activation of TGF-beta-mediated signaling pathways. TGF-beta, a pro-inflammatory mediator that is mutated and/or overexpressed in a number of cancer cell types, is involved in cancer cell proliferation and migration, and tumor progression.]
RASVAC-C	NCIT_C29401	[A synthetic vaccine used for cancer immunotherapy also known as Ras(cis 12)-Vaccinia Vaccine, RASVAC-C is based on a mutant peptide epitope of the Ras oncoprotein at codon 12 that induces recognition and induction of tumor-specific, cell-mediated immune responses. Ras is an intracellular GTP-binding protein involved in signal transduction and regulation of proliferation and differentiation. (NCI04)]
Autologous PD-1-targeted Chimeric Switch Receptor-modified T Lymphocytes	NCIT_C132251	[Autologous human T-lymphocytes that are genetically engineered to express a chimeric switch receptor (CSR) composed of the extracellular ligand binding domain of the human inhibitory receptor programmed cell death protein 1 (PD-1; PDCD1) fused to the transmembrane and cytoplasmic co-stimulatory signaling domains of CD28 (PD1CD28; PD-1:CD28 switch receptor), with potential immunomodulating and antineoplastic activities. Upon reintroduction of autologous PD-1-targeted CSR-modified T-lymphocytes into the patient, the switch receptor expressed by the engineered T-cells targets and binds to the PD-1 ligands, programmed cell death ligand 1 (PD-L1) and 2 (PD-L2) expressed, on tumor cells. The nature of the PD-1/CD28 switch receptor fusion protein prevents the normal PD1/PD-L1-mediated T-cell suppression and, instead, promotes signaling through the CD28 domain, which results in the stimulation of T-lymphocytes. This induces enhanced toxicity against PD-L1-expressing tumor cells. PD-1 protein, found on activated T-cells, negatively regulates T-cell activity; it plays a key role in immune evasion and prevents tumor cell lysis. Exchanging the transmembrane and intracellular domain of PD-1 with that of CD28 converts PD-L1 into a co-stimulation ligand of primary human CD8+ cytotoxic T-lymphocytes (CTLs). CD28, is a molecule expressed by T-cells that stimulates increased T-lymphocyte proliferation and activity.]
RASVAC-V	NCIT_C29402	[A synthetic vaccine used for cancer immunotherapy also known as Ras(val 12)-Vaccinia Vaccine, RASVAC-C is based on a mutant peptide epitope of the Ras oncoprotein at codon 12 (valine instead of glycine) that induces recognition and induction of tumor-specific, cell-mediated immune responses. Ras is an intracellular GTP-binding protein involved in signal transduction and regulation of proliferation and differentiation. (NCI04)]
Anti-PD-1 Monoclonal Antibody BI 754091	NCIT_C132252	[A monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed cell death protein 1 (PD-1; PDCD1), with immune checkpoint inhibitory and antineoplastic activities. Upon administration, BI 754091 selectively binds to and blocks the activation of PD-1, an immunoglobulin (Ig) superfamily transmembrane protein, by its ligands programmed cell death ligand 1 (PD-L1), which is overexpressed on certain cancer cells, and programmed cell death ligand 2 (PD-L2), which is primarily expressed on antigen-presenting cells (APCs). This results in the activation of T-cells and T-cell-mediated immune responses against tumor cells. Activated PD-1 negatively regulates T-cell activation and plays a key role in in tumor evasion from host immunity.]
Cooperative Donor Registry	NCIT_C132253	[A formal business relationship between donor registries allowing for tissue matching against the pool of donors created by all participating registries.]
Aziridinylbenzoquinone RH1	NCIT_C29404	[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.]
BTK Gene Mutation	NCIT_C132254	[A change in the nucleotide sequence of the BTK gene.]
BTK Gene	NCIT_C75013	[This gene is involved in both signaling and B-cell development.]
Rhizoxin Diluent	NCIT_C29405
SmartPill	NCIT_C132255	[A proprietary ingestible capsule for gastrointestinal tract functional assessment that measures pressure, pH, temperature, and transit time as it travels through the entire gastrointestinal tract.]
Rifamycin	NCIT_C29406	[A natural antibiotic produced by Streptomyces mediterranei, Rifamycin (Ansamycin Family) is a commonly used antimycobacterial drug that inhibits prokaryotic DNA-dependent RNA synthesis and protein synthesis; it blocks RNA-polymerase transcription initiation. Rifamycin has an activity spectrum against Gram-positive and Gram-negative bacteria, but is mainly used against Mycobacterium sp. (especially M. tuberculosis) in association with other agents to overcome resistance. (NCI04)]
Unspecified Tissue	NCIT_C132256	[A tissue specimen whose anatomic origin is not known or reported.]

Natural Product	NCIT_C66892	[Any whole or part of a plant (including plant exudates), animal or microorganism that is unprocessed (raw material), or that has been processed, pulverized or extracted. Many of the natural products have some biological and/or pharmacological activity or are used for a specific purpose, not necessarily medicinal (food, aroma therapy, research and etc.). This class does not include any individual substance derived from plants/animals or other organisms with specific pharmacologic activity (See Drug, Natural Product).]
Citrus bergamia Extract	NCIT_C107291	[The oil extracted from the fruit peel of Citrus bergamia. Bergamot oil is used in the treatment of psoriasis, mycosis fungoides, and vitiligo. Additionally, it is used as a citrus flavoring agent.]
