Abstract:
TPS3638 Background: A promising approach for the treatment of cancer is the development of vaccines that target specific tumor antigens. In the metastatic CRC patient population, targeted and active immunotherapy may inhibit cancer progression and improve survival. This trial is designed to evaluate the efficacy, immunogenicity, and safety of GI-4000 plus standard therapy in patients with metastatic colorectal cancer. GI-4000 is a proprietary immunotherapy that uses whole, heat-killed recombinant Saccharomyces cerevisiae yeast (called Tarmogens = Targeted Molecular Immunogens). GI-4000 is designed to activate a cellular immune response to target cells with activating ras mutations. Tarmogens have been shown to elicit selective killing of target cells that express a number of cancer antigens, including mutated Ras, by activation of antigenspecific T cell mediated responses. Methods: The study population consists of subjects with metastatic colorectal cancer with an activating mutation in ras. Newly diagnosed subjects receive FOLFOX (or FOLFIRI) + bevacizumab (Bev) + GI- 4000; 3 weekly injections of GI-4000 are followed by 8 cycles of Bev + FOLFOX (or FOLFIRI); day 1 and 2 every 14 days. Doses of GI-4000 are administered on day 8 of each cycle. Upon completion of chemotherapy, GI-4000 continues along with Bev maintenance every 2 weeks for up to 5 years or until subjects experience intolerance, disease recurrence, or death. If Bev is stopped, GI-4000 may continue on the same maintenance schedule alone. Subjects that have already completed standard chemotherapy (FOLFOX or FOLFIRI) may enter the study and receive Bev + GI-4000 every 2 weeks for up to 5 years. Enrollment is ongoing and will continue up to 52 subjects.
