autologous mesenchymal stem cells apceth_101

Human autologous mesenchymal stem cells (MSCs) harvested from the bone marrow of a patient and genetically modified with a self-inactivating retroviral vector expressing the suicide gene herpes simplex virus thymidine kinase (HSV-TK), that can be used to activate synthetic acyclic guanosine analogues when co-administered. Upon intravenous administration of autologous mesenchymal stem cells apceth_101, the cells are actively recruited to the tumor stroma, differentiate into more mature mesenchymal cells, and become part of the tumor microenvironment. When a synthetic acyclic guanosine analogue, such as ganciclovir, is co-administered, the HSV-TK within the HSV-TK-transduced MSCs will monophosphorylate this prodrug. Subsequently the monophosphate form is further converted to the diphosphate form and then to its active triphosphate form by cellular kinases. The active form of ganciclovir kills the HSV-TK-transduced MSCs and leads to a bystander effect, which eliminates neighboring cancer cells. Therefore, synthetic acyclic guanosine analogues are activated only at the tumor site, which increases their local efficacy and reduces systemic toxicity.

autologous PD-1-targeted chimeric switch receptor-modified T lymphocytes

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. Check for active clinical trials using this agent. (NCI Thesaurus)

autologous peripheral blood lymphocytes cotransduced with retroviral vectors encoding inducible IL-12 and anti-NY-ESO-1 TCR

Human autologous peripheral blood lymphocytes (PBLs) transduced with two retroviral vectors, one encoding a T-cell receptor (TCR) specific for the cancer-testis antigen NY-ESO-1 and a second that encodes an inducible single-chain form of interleukin-12 (IL-12) driven by a nuclear factor of activated T-cells (NFAT)-responsive promoter, with potential immunomodulating and antineoplastic activities. Following isolation of lymphocytes, retroviral vector transduction, and expansion of the cells ex vivo, the inducible IL-12/anti-NY-ESO-1 TCR-expressing autologous PBLs are re-administered into the patient by intravenous injection. As the transduced PBLs traverse the patient's circulatory system, they can bind to NY-ESO-1-overexpressing tumor cells. This binding activates the TCR signaling pathway in the transduced PBLs, which promotes NFAT-dependent gene transcription and induces expression of the cotransduced IL-12. IL-12 expression activates the immune system by promoting the secretion of interferon-gamma, activating natural killer cells (NKs), and inducing cytotoxic T-cell responses, which may result in both decreased cell proliferation and increased cell death for the NY-ESO-1-overexpressing tumor cells. NY-ESO-1, a tumor-associated antigen (TAA), is found in normal testis and on the surface of various tumor cell types. NFAT, a family of transcription factors involved in immune responses, is activated by calcium signaling, which can occur downstream of TCR activation. Use of a retroviral vector to express an inducible IL-12 may remove the requirement for concomitant administration of interleukin-2 (IL-2) that is a component of conventional cell transfer immunotherapies.

autologous prostate stem cell antigen-specific CAR T cells BPX-601

A preparation of autologous T lymphocytes expressing a chimeric antigen receptor (CAR) consisting of an anti-human prostate stem cell antigen (PSCA) scFv (single chain variable fragment) coupled to the zeta chain of the T-cell receptor (TCRzeta) and a drug-induced co-stimulatory molecule, composed of an inducible, chimeric MyD88/CD40 (inducible MC; iMC) co-stimulatory domain, in which both the MyD88 and CD40 lack their extracellular domains, with potential antineoplastic activity. Upon administration of BPX-601, the T cells target and bind to PSCA-expressing cancer cells. Upon subsequent administration of the chemical inducer of dimerization (CID) agent rimiducid, this agent targets and binds to the drug binding domain, which leads to iMC expression, activation of both CD40- and MyD88-mediated signal transduction pathways, and an induction of selective cytotoxicity in, and eradication of PSCA-expressing cancer cells. iMC activation by rimiducid increases T-cell survival and anti-tumor activity of the administered T cells, compared to T cells without the drug iMC activation-switch. As these T cells are engineered to only be fully activated by binding to both antigen and rimiducid, T-cell proliferation, activity and toxicity can be controlled by adjusting the dose of rimiducid, thereby preventing uncontrolled T-cell activation which increases the safety of the administered T cells. PSCA is a glycosylphosphatidylinositol (GPI)-anchored cell surface antigen overexpressed in many cancer cell types. Check for active clinical trials using this agent. (NCI Thesaurus)

An aziridinyl-substituted cyclophosphazene and a putrescence derivative that may cause DNA cross-linkage. Check for active clinical trials using this agent. (NCI Thesaurus)

aztreonam

A monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum with bactericidal activity. Aztreonam preferentially binds to and inactivates penicillin-binding protein-3 (PBP-3), which is involved in bacterial cell wall synthesis, thereby inhibiting bacterial cell wall integrity and leading to cell lysis and death. This agent differs from other beta-lactam antibiotics because it is resistant to beta-lactamase hydrolysis, and it is usually used to treat infections caused by gram-negative aerobic microorganisms.

Azulfidine

(Other name for: sulfasalazine)

azurin-derived cell-penetrating peptide p28

A water-soluble, amphipathic, 28 amino acid (amino acids 50-77), 2.9 kD fragment peptide (p28) derived from the protein azurin with potential antineoplastic and antiangiogenic activities. Although the mechanism has yet to be fully elucidated, the preferential cellular uptake of azurin-derived cell-penetrating peptide p28 by tumor cells and endothelial cells is likely via caveolae-mediated endocytosis; the C-terminal 18 amino acid residues (50-67) appear to responsible for this preferential uptake. After cell entry, the first 12 amino acid residues interact with tumor suppressor p53 and form a p28:p53 complex, which may result in a reduction of proteasomal degradation of p53, increased p53 levels, and p53-mediated cell cycle inhibition and apoptosis. Azurin is a cupredoxin secreted by the bacterium Pseudomonas aeruginosa. Cell penetrating peptides (CPPs) are cationic and/or amphipathic peptides, typically less than 30 amino acids in length, that can penetrate cell membranes easily and may transport molecular cargo.
