- Data Presented at the American Association for Cancer Research -
PRINCETON, N.J., April 21 /PRNewswire-FirstCall/ -- Medarex, Inc. (Nasdaq: MEDX) today announced preclinical efficacy and safety data from multiple programs, including antibodies to novel and potentially important cancer targets (CXCR4, fucosyl-GM1, glypican-3, mesothelin, CD70) and additional research in the area of antibody-drug conjugates. Data from the studies were presented at the Annual Meeting of the American Association for Cancer Research (AACR), April 18-22, 2009, in Colorado.
Characterization of MDX-1338, a human anti-CXCR4 antibody proposed for therapeutic application in AML and ALL (Abstract #LB-150)
CXCR4 is a seven-transmembrane, G-protein-coupled receptor in the CXC chemokine receptor family that is expressed on a variety of cancers including leukemias, lymphomas, breast, lung, colon, pancreatic, and ovarian cancer. In preclinical studies, MDX-1338, a fully human anti-CXCR4 antibody, effectively blocked the binding of CXCR4 to its ligand, CXCL12, thereby inhibiting chemotaxis and migration responses. In addition, MDX-1338 also reduced tumor growth in acute myelogenous leukemia and lymphoma xenograft models.
Efficacy of MDX-1110, an anti-Fucosyl-GM1 antibody in a SCLC tumor model (Abstract #838)
Fucosyl-GM1 is a ganglioside, a component of the cell plasma membrane, that is expressed on most small cell lung cancers (SCLC). In in vitro preclinical studies, a fully human, non-fucosylated anti-fucosyl-GM1 antibody, MDX-1110, demonstrated robust cytotoxic effector function (both antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity) for killing tumor cells. Additionally, MDX-1110 showed a favorable safety and toxicity profile. MDX-1110 also demonstrated potent anti-tumor a
