ImmunoCellular Therapeutics' Founder and Chief Scientific Officer, John Yu, MD, Presents at "Targeting Cancer Stem Cells" Symposium

Featured Talk Emphasizes Importance of Antigen-Specific Dendritic Cell Cancer Vaccines to Generate Powerful T-Cell Response

LOS ANGELES, Feb. 14, 2014 /PRNewswire/ -- ImmunoCellular Therapeutics, Ltd. ("ImmunoCellular") (NYSE MKT: IMUC) today announced that the Company's Founder and Chief Scientific Officer, John S. Yu, MD, delivered a presentation highlighting the therapeutic importance of utilizing antigen-specific dendritic cell (DC) cancer vaccines for inducing a potent T-cell response and destroying tumor cells as well as cancer stem cells. Dr. Yu's presentation took place today in a session titled "Dendritic Cell Vaccines Targeting Cancer Stem Cells" at Cambridge Healthtech Institute's Third Annual "Targeting Cancer Stem Cells: New Opportunities for Oncology Therapeutics," which is part of the 21st Annual Molecular Medicine Tri Conference, in San Francisco. 


During his presentation, Dr. Yu described ImmunoCellular's proprietary DC-based immunotherapeutic vaccines, which are designed to target both tumor cells and cancer stem cells by utilizing multiple, validated tumor-specific antigens to trigger a powerful antitumor immune system response. Dr. Yu contrasted ImmunoCellular's approach with other cancer vaccine technologies, including tumor lysates, which may only include a small amount of tumor-specific antigens and may induce a weaker antibody-based immune response, and noted by contrast that antigen-specific DC-based vaccines have the potential to mount a T-cell response that may be more robust, efficient and tumor-specific. By way of illustration, in describing the design of ICT-107, the Company's vaccine to treat glioblastoma (GBM), Dr. Yu noted that the six specific antigens in this vaccine have been validated as expressed on GBM cells and having important roles in tumor growth. Dr. Yu observed that patients with GBM whose tumors express these six antigens generally have a poorer clinical prognosis. By enabling DCs to recognize and process specific antigens, a stronger T cell response can be induced with a view to effectively killing cancer cells and cancer stem cells, potentially leading to a superior cancer vaccine.

"The core premise of ImmunoCellular's cancer vaccine approach is that the key to targeting cancer is targeting cancer stem cells for destruction," said Dr. Yu. "Immunologically, the ability to enable dendritic cells to induce a powerful T-cell response requires that they recognize and efficiently process or mount a response to specific antigens on tumors that can lead to effective cancer cell and cancer stem cell death. T cells are the most powerful, and one could argue, the primary weapon in the immune system that can kill tumors, which is why we have designed our cancer vaccines to specifically and selectively trigger their activation."
