Summary:
Dr. John Dick, Senior Scientist at the Ontario Cancer Institute, the research arm of Princess Margaret Hospital, part of the University Health Network, co-led a multinational team that has developed the first leukemia therapy that targets a protein, CD123, on the surface of cancer stem cells that drive acute myeloid leukemia (AML), which is an aggressive disease with a poor outcome. Dr. Richard Lock is leading the clinical trial in Australia that expands on research suggesting that antibodies targeting cancer stem cells significantly reduced the growth of human AML cells that had been transplanted into immune-deficient mice, a laboratory model that mimics the human disease, establishing the therapeutic potential of this type of therapy. The research paper Monoclonal Antibody-Mediated Targeting of CD123, IL-3 Receptor α Chain, Eliminates Human Acute Myeloid Leukemic Stem Cells was published in Cell Stem Cell July 2, 2009.
