MALVERN, Pa., Dec. 11, 2011 /PRNewswire/ -- TetraLogic Pharmaceuticals, a biopharmaceutical company developing novel small molecule Smac mimetic drugs to treat cancer, today announced the oral presentation of new data on its Smac mimetic drug candidate TL32711 at the 53rd ASH Annual Meeting and Exposition in San Diego. The study, conducted at The University of Texas M. D. Anderson Cancer Center, demonstrated that TL32711 induces apoptosis in acute myeloid leukemia (AML) cells, including AML stem/progenitor cells, alone and in combination with chemotherapy.
"TL32711 demonstrated single agent activity against blasts obtained from newly diagnosed AML patients and in CD34+38- stem/progenitor cells isolated from blasts of these patients, with no toxicity in CD34+ cells from normal bone marrows at doses effective against AML cells," said Michael Andreeff, M.D., Ph.D. Professor of Medicine and Chief, Molecular Hematology & Therapy, Departments of Leukemia and Stem Cell Transplantation & Cellular Therapy at The University of Texas MD Anderson Cancer Center. "When combined with various nucleoside analogues clinically used in AML therapy such as Ara-C, clofarabine, and demethylating agents decitabine and 5-azacytidine, TL32711 synergistically enhanced apoptotic cell death in AML cells and AML stem/progenitor cells."
TetraLogic recently announced the initiation of a Phase 1/2 clinical trial of TL32711 in elderly patients with AML. The investigator-initiated study is being conducted at the Hospital of the University of Pennsylvania and is an open-label, non-randomized trial that will evaluate the safety, tolerability and clinical response activity of TL32711 in patients aged 60 years or greater who have relapsed or primary refractory AML.
TL32711 is a small molecule peptidomimetic of Smac (Second mitochondrial-derived activator of caspases) an endogenous regulato
