An immunoconjugate of a humanized murine monoclonal antibody (huN-901) and DMI, a semi-synthetic derivative of the plant-derived ansa macrolide maytansine. The antibody moiety of lorvotuzumab mertansine selectively attaches to CD56 antigen, a neural cell adhesion molecule (NCAM)) expressed on the surface of cells of small cell lung cancer (SCLC) and other neuroendocrine (NE) tumors. Thus, the DMI conjugate is targeted specifically to CD56-expressing tumor cells, where it inhibits tubulin polymerization and assembly, resulting in inhibition of mitosis and cell cycle arrest in the S phase.

An immunoconjugate that consists of a humanized monoclonal antibody (MLN591), directed against prostate-specific membrane antigen linked to a maytansinoid (DM1). The monoclonal antibody moiety of MLN2704 binds to tumor cells expressing prostate-specific membrane antigen; MLN274 is then internalized into the tumor cell where the DM1 maytansinoid moiety binds to tubulin and inhibits tubulin polymerization and microtubule assembly, resulting in a disruption of microtubule activity and cell division, and cell death.

An immunocytokine consisting of human pro-inflammatory cytokine tumor necrosis factor alpha (TNFalpha) fused to a human single-chain variable fragment (scFv) directed against the extra-domain B (ED-B) of fibronectin (L19), with potential immunopotentiating and antineoplastic activities. The L19 moiety of recombinant human fusion protein L19TNFalpha binds to the ED-B domain of fibronectin on tumor cells in the tumor neovasculature. In turn, the TNFalpha moiety may locally induce an immune response against ED-B fibronectin-expressing tumor cells and may specifically decrease the proliferation of ED-B-expressing tumor cells. ED-B is predominantly expressed during angiogenesis and tumor growth.

An immunocytokine of the human monoclonal antibody fragment F16 (scFv) against the extra-domain A1 of tenascin-C fused, via a short 5-amino acid linker, to a recombinant form of the human cytokine interleukin-2 (IL-2) with potential immunostimulating and antineoplastic activities. The monoclonal antibody portion of the F16-IL2 fusion protein binds to tumor cells expressing the tumor associated antigen (TAA) tenascin-C. In turn, the IL-2 moiety of the fusion protein stimulates natural killer (NK) cells, macrophages and neutrophils and induces T-cell antitumor cellular immune responses thereby selectively killing tenascin-C-expressing tumor cells. In addition, F16-IL2 may potentiate the cytotoxicity of other chemotherapeutic agents. Tenascin-C, a glycoprotein of the extracellular matrix, is expressed in many cancer cell types.

An immunotherapeutic consisting of the recombinant fusion protein WT1-A10 combined with the adjuvant ASO1B with potential immunostimulating and antineoplastic activities. Upon administration, WT1-A10/AS01B immunotherapeutic GSK2130579AWT1 may induce a WT1-specific cytotoxic T-lymphocyte (CTL) response against WT1-expressing tumor cells, resulting in cell lysis and the inhibition of cellular proliferation. The tumor-associated antigen WT1 (Wilms tumor protein-1) is overexpressed in most types of leukemia and in a variety of solid cancers. WT1-A10 is a 292 amino acid recombinant fusion protein consisting of a 12-mer truncated tat sequence (leader sequence) and amino acids number 2-281 of the WT1 sequence; ASO1B consists of a combination of the adjuvants monophosporyl lipd A (MPL) and Q21.
Industry:Pharmaceutical
An immunotherapeutic containing a proprietary adjuvant system combined with a melanoma-associated antigen peptide MAGE-A3 epitope with potential immunomodulating and antineoplastic activities. Intramuscular administration with GSK1572932A may stimulate the immune system to exert both humoral and cellular immune responses against MAGE-A3-expressing tumor cells. MAGE-A3, a tumor associated antigen (TAA), is overexpressed in a variety of tumor cell types, including non-small cell lung cancer (NSCLC), melanoma, head and neck cancer, and bladder cancer.
Industry:Pharmaceutical
An immunotherapy regimen containing three components: a plasmid encoding portions of the two melanoma-associated antigens Melan A (also called MART-1) and tyrosinase and two synthetic analogs of Melan-A and tyrosinase antigen epitopes with potential immunostimulating and antitumor activities. First, the plasmid is injected directly into lymph nodes in order to sensitize or prime antigen-presenting cells (APCs) and central memory T cells in lymph nodes to plasmid-expressed Melan A and tyrosinase. After several priming injections with plasmids, the Melan A and tyrosinase synthetic epitope analogs are injected directly into lymph nodes; upon binding to major histocompatibility complex (MHC) molecules on APC cell surfaces, these synthetic epitope analogs may stimulate a "primed" cytotoxic T lymphocyte (CTL) response against melanoma tumor cells, resulting in tumor cell lysis. Melan-A and tyrosinase are overexpressed by melanoma tumor cells.

An immunotoxin comprised of an anti-B4 (anti-CD19) murine monoclonal antibody linked to the modified plant-derived toxin blocked ricin. The antibody moiety of anti-B4 blocked ricin immunotoxin binds to B lymphocytes that express B4; after internalization of the immunotoxin by the B4-expressing B cell, the ricin moiety cleaves the N-glycosidic bond between the ribose and adenine base at position 4324 in the B lymphocyte 28S ribosomal RNA, resulting in ribosome inactivation, inhibition of protein synthesis, and cell death. "Blocked" ricin is ricin which has been chemically modified such that the lectin binding sites of the B chain (galactose-binding sites) have been blocked by covalent attachment of affinity ligands, leaving the ribosome-inactivating activity of the ricin A chain intact.
Industry:Pharmaceutical
An immunotoxin consisting of a monoclonal antibody directed against epithelial glycoprotein-2 (EP-2, or epithelial cell adhesion molecule (EpCAM)) conjugated to the bacterial toxin Pseudomonas exotoxin A (PE) with potential antineoplastic activity. Upon administration of anti-EGP-2 immunotoxin MOC31-PE, the monoclonal antibody moiety targets and binds to EP-2. Upon internalization, the Pseudomonas exotoxin A moiety then inactivates elongation factor 2 (EF-2) through ADP ribosylation, resulting in inhibition of protein synthesis in EP-2-expressing cells. EP-2, a tumor-associated antigen, is overexpressed in a variety of cancer cell types.
Industry:Pharmaceutical
An immunotoxin consisting of two scFv ligands recognizing human CD19 and CD22 linked to the first 389 amino acids of diphtheria toxin (DT), DT 390, with potential antineoplastic activity. The VH and VL regions of anti-CD22 (sFv) and anti-CD19 are reversed and linked by an aggregration stabilizing linker (ARL) consisting of a 20 amino acid segment of human muscle aldolase (hma) and an Xho1 -compatible restriction site; the CDR3 region of the VH of anti-CD22 sFv is mutated to enhance its affinity. The anti-CD19 and anti CD-22 portions of the immunotoxin specifically bind to CD19 and CD22 receptors on tumor B cells. Upon internalization, DT catalyzes ADP ribosylation of elongation factor 2 (EF-2) which may result in the irreversible inhibition of protein synthesis and cell death in CD19- and CD22-expressing tumor cells. CD19 and CD22 transmembrane proteins upregulated on malignant B cells.
