V930 vaccine
vaccine-sensitized draining lymph node cells
Cells isolated from lymph nodes from patients, and activated in vitro to generate tumor-specific effector T cells. Lymph nodes in the lymphatics draining tumors often contain T cells that are immunologically sensitized but functionally deficient. Vaccine-sensitized draining lymph node cells are prepared by isolating these lymphocytes in vitro and stimulating them with cytokines to differentiate into mature effector cells. Vaccine-draining lymph node cells may also be produced by pharmacological activation of lymph node-derived lymphocytes with drugs such as ionomycin or with bacterial toxin; these activated lymphocytes may be expanded in culture with cytokines such as interleukin-2 prior to infusion into the patient.

vaccinia virus (vvDD-CDSR)
A highly tumor-selective vaccinia virus (vv) with an engineered double deletion (DD) of the thymidine kinase (tk) and vaccinia growth factor genes and additions of both a cytosine deaminase (CD) gene and a somatostatin receptor (SR) gene with potential oncolytic viral activity. The tk and vaccinia growth factor gene deletions in intratumorally administered vaccinia virus (vvDD-CDSR) help to restrict its replication and cytolytic activity to tumor cells with large nucleotide pools and tumor cells with activation of the EGFR-Ras pathway. Addition of the CD gene to the viral genome allows control of oncolytic viral infection through the administration of the prodrug 5-fluorocytosine (5-FC), converted by CD to the antimetabolite 5-fluorouracil (5-FU) in cells infected with this agent. Addition of the SR gene allows anatomical localization of vaccinia virus (vvDD-CDSR) through the use of octreotide scintigraphy.

Vagestrol
(Other name for: diethylstilbestrol)
|
valacyclovir
The hydrochloride salt of the L-valyl ester of the antiviral drug acyclovir. Orally administered, valacyclovir is rapidly converted to acyclovir which inhibits viral DNA replication after further conversion to the nucleotide analog acyclovir triphosphate by viral thymidine kinase, cellular guanyl cyclase, and a number of other cellular enzymes. Acyclovir triphosphate competitively inhibits viral DNA polymerase; incorporates into and terminates the growing viral DNA chain; and inactivates viral DNA polymerase. The greater antiviral activity of acyclovir against herpes simplex virus (HSV) compared with varicellla-zoster virus (VZV) is due to its more efficient phosphorylation by HSV thymidine kinase. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
|
Valcyte
(Other name for: valganciclovir)
|
valdecoxib
A sulfonamide derivative and non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic, and antipyretic activities. Valdecoxib selectively binds to and inhibits cyclooxygenase (COX)-2, thereby preventing the conversion of arachidonic acid into prostaglandins, which are involved in the regulation of pain, inflammation, and fever. This NSAID does not inhibit COX-1 at therapeutic concentrations and therefore does not interfere with blood coagulation. Check for active clinical trials or closed clinical trials using this agent.

|
valproic acid
A synthetic derivative of propylpentanoic acid with antiepileptic properties and potential antineoplastic and antiangiogenesis activities. In epilepsy, valproic acid appears to act by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. This agent's antitumor and antiangiogenesis activities may be related to the inhibition of histone deacetylases and nitric oxide synthase, which results in the inhibition of nitric oxide synthesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
|
valrubicin
A semisynthetic derivative of the antineoplastic anthracycline antibiotic doxorubicin. With a mechanism of action that appears to differ from doxorubicin, valrubicin is converted intracytoplasmically into N-trifluoroacetyladriamycin, which interacts with topoisomerase II, stabilizing the complex between the enzyme and DNA; consequently, DNA replication and repair and RNA and protein synthesis are inhibited and the cell cycle is arrested in the G2 phase. In addition, this agent accumulates in the cell cytoplasm where it inhibits protein kinase C (PKC). Valrubicin is less cardiotoxic than doxorubicin when administered systemically; applied topically, this agent shows excellent tissue penetration. Structurally, the trifluoro-acetyl moiety on the amino group of the glycoside and the valerate moiety appear to result in a lipophilicity that is greater than of doxorubicin, resulting in increased intracytoplasmic concentrations.

Vincasar PFS
(Other name for: vincristine sulfate)
|
vincristine sulfate
The sulfate salt of a natural alkaloid isolated from the plant Vinca rosea Linn with antimitotic and antineoplastic activities.

Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
|
vindesine
A synthetic derivative of vinblastine, a naturally occurring vinca alkaloid.

Compared to other vinca alkaloids, this agent binds weakly to the vinca-binding site, indicating that vinflunine may exhibit reduced neurotoxicity. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
|
vinorelbine ditartrate
The ditartrate salt of a semisynthetic vinca alkaloid derived from the leaves of the periwinkle plant (Vinca rosea) with antineoplastic properties.

Inhibition of mitotic microtubules correlates with antitumor activity, whereas inhibition of axonal microtubules seems to correlate with vinorelbine's neurotoxicity. Compared to related vinca alkaloids, vinorelbine is more selective against mitotic than axonal microtubules in vitro, which may account for its decreased neurotoxicity. This agent is also a radiation-sensitizing agent. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
|
vinorelbine tartrate emulsion
An emulsion containing the tartrate salt of the semisynthetic vinca alkaloid vinorelbine with antineoplastic activity.

In this formulation vinorelbine is emulsified in a homogeneous suspension of nanoparticles, which protects the venous endothelium from coming into direct contact with the active ingredient, potentially reducing vinorelbine-associated venous toxicity at the venous injection site.

visilizumab
A humanized, non-Fc receptor (FcR)-binding IgG2 monoclonal antibody (MoAb) directed against CD3 with potential immunosuppressive activity. Visilizumab binds to invariant CD3 epsilon, one of the non-covalently-associated subunits of T-cell receptors (TCRs) on activated T-cells. Upon binding to the TCR/CD3 complex, visilizumab induces apoptosis, which may result in the selective clonal deletion of activated pathogenic T-cells. This MoAb is engineered with a substitution at amino acid residues 234 and 237 (Val3Ala) within the IgG2 Fc arm, rendering it unable to bind to type II FcRs; accordingly, this agent is less likely to activate type II FcR-expressing resting T-cells.

|
vorinostat
A synthetic hydroxamic acid derivative with antineoplastic activity. Vorinostat, a second generation polar-planar compound, binds to the catalytic domain of the histone deacetylases (HDACs). This allows the hydroxamic moiety to chelate zinc ion located in the catalytic pockets of HDAC, thereby inhibiting deacetylation and leading to an accumulation of both hyperacetylated histones and transcription factors. Hyperacetylation of histone proteins results in the upregulation of the cyclin-dependant kinase p21, followed by G1 arrest. Hyperacetylation of non-histone proteins such as tumor suppressor p53, alpha tubulin, and heat-shock protein 90 produces additional anti-proliferative effects. This agent also induces apoptosis and sensitizes tumor cells to cell death processes. Vorinostat crosses the blood-brain barrier.
