RARITAN, N.J., June 4 /PRNewswire/ -- Ortho Biotech Oncology Research & Development, a unit of Centocor Research & Development, Inc., today announced that it has entered into a five-year Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI), with Steven A. Rosenberg, M.D., Ph.D., chief, Surgery Branch, serving as the NCI principal investigator, to research and develop novel cell therapy technologies as potential treatments for a variety of cancers. These adoptive immunotherapy technologies are designed to work by helping the immune system fight cancer. Standard cancer treatments still have not progressed much beyond surgery, radiation and chemotherapy, which are effective at killing tumor cells but also can harm or kill healthy tissues. Adoptive immunotherapies have the potential to spare healthy tissue because they are designed to directly find and destroy cancerous tumor cells using a patient's own immune system T cells.
Dr. Rosenberg has been a pioneer in the field of adoptive immunotherapy of cancer for decades. His group developed Tumor Infiltrating Lymphocytes (TILs), T cells obtained from a patient's tumor, expanded and then re-administered to actively seek and destroy cancer cells. Remarkable responses to this therapy have been observed in patients with malignant melanoma, a type of skin cancer that ranks sixth among U.S. men and seventh in U.S. women for the most commonly diagnosed cancer, according to the NCI. In recent years, Dr. Rosenberg's team pioneered a new technology in which T cells obtained from a patient's blood are genetically engineered to express receptors that give them specific immunity against cancer cells and then re-administered.
Researchers at Ortho Biotech Oncology Research & Development independently developed a different and proprietary adoptive immunotherapeutic approach that uses tumor antigens and other materials to stimulate T cells
