Rodell, M.D., GlobeImmune's President and CEO. "This Tarmogen, in combination with targeted cancer therapies such as imatinib, may make these small molecule drugs more effective by preventing or treating resistance." In this study, leukemic cells with and without the T315I mutation were transferred into recipient mice, half of which had received the T315I Tarmogen and half of which were left untreated. Animals receiving the T315I-specific Tarmogen were protected from challenge as measured both by the percentage of circulating leukemic cells as well as survival compared to untreated mice. About GI-10001 Tarmogens (Targeted Molecular Immunogens) are a proprietary, immunotherapeutic platform utilizing whole, heat-killed recombinant Saccharomyces cerevisiae yeast genetically modified to express disease-specific protein targets. The GI-10001 Tarmogen expresses the threonine-to-isoleucine mutation at codon 315 of Bcr-Abl (T315I mutation). This is the most prevalent escape mutation to imatinib, dasatinib, and nilotinib which are common treatments for CML. Additionally, GlobeImmune is investigating a version of GI-10001 that directly targets the causative Bcr-Abl junctional mutation in an analogous model. About Chronic Myelogenous Leukemia (CML) CML is cancer of the blood system in which too many white blood cells belonging to the myeloid line of cells are produced in bone marrow. CML is the result of growth and evolution of an abnormal chromosome rearrangement known as the Philadelphia chromosome which contains a fused Bcr-Abl gene. The goal of treatment is to stabilize the level of blood cells and eliminate all cells with the Bcr-Abl gene. Many CML patients are treated with a targeted cancer drug called imatinib mesylate or one of the several second generation inhibitors of Abl kinase for the treatment of CML. The American Cancer Society estimates that in 2007 there will be about 4,570 new cases of CML in the United States and that about 490 will die of the disease. About 21,501 people in the United States are currently living with CML. The average age of people with CML is around 66 years. About GlobeImmune, Inc. GlobeImmune is a private Colorado-based company developing active immunotherapies called Tarmogens for the treatment of cancer and infectious diseases. The Company's lead product candidate, GI-5005, is a Tarmogen being developed for the treatment of chronic hepatitis C infection that has completed Phase 1b clinical trials. GI-5005 is designed to complement both the current and emerging standard of care for hepatitis C infection through the direct elimination of chronically infected cells. The Company plans to initiate a randomized, placebo-controlled Phase 2 study of GI-5005 in combination with standard of care for chronic hepatitis C infection before the end of 2007. The Company's lead oncology program, GI-4000, is designed to be a treatment for cancers of the lung and gastrointestinal tract. A randomized, placebo-controlled Phase 2 trial in patients with resectable pancreas cancer in combination with adjuvant gemcitabine is ongoing.
