MALVERN, Pa., Dec. 5, 2011 /PRNewswire/ -- TetraLogic Pharmaceuticals, a biopharmaceutical company developing novel small molecule Smac mimetic drugs to treat cancer, today announced the initiation of a Phase 1/2 clinical trial of its lead Smac mimetic drug candidate, TL32711, in elderly patients with acute myelogenous leukemia (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.
"In preclinical studies on primary human AML samples, TL32711 inhibits the growth and survival of AML cells as demonstrated in colony forming assays and a xenotransplantation model of the disease," said Martin Carroll, M.D., of the Hospital of the University of Pennsylvania. "These encouraging data along with TL32711's novel mechanism of action support its clinical development for AML where new treatment options are needed especially for the elderly."
"This clinical study represents another important step in advancing TL32711 as a potential treatment for AML and supports our goal of providing improved therapies for patients with cancer," said John Gill, TetraLogic's President and Chief Executive Officer. "The ability of TL32711 to antagonize Inhibitor of Apoptosis Proteins (IAPs) represents a new broadly applicable approach to treat cancers that are normally resistant to therapies, including AML."
TL32711 is a small molecule peptidomimetic of Smac (Second mitochondrial-derived activator of caspases) an endogenous regulator of apoptotic cell death that selectively antagonizes multiple IAPs. TL32711 has demonstrated preclinical anti-tumor activity that supports its clinical development for solid tumor and hematological malignancies as a monotherapy and in combination with other anti-cancer therapies. TL32711 is nearing completion of a single agent Phase 1 study in solid tumors and lymphomas and a Phase 1b five-arm combination clinical study in solid tumors. In the clinical studies to date, TL32711 has been well tolerated and exhibited rapid suppression of IAPs and antitumor activity.
