Groundbreaking advances in immunotherapy have revolutionized the treatment of cancer. In particular, new antibody drugs that block immunosuppressive pathways have achieved remarkable success in reawakening the immune system to clear tumor cells, leading to lasting cures in patients whose cancers do not respond to any other therapies. Unfortunately, the majority of patients (>70%) do not respond to immunotherapy treatment. It is difficult to predict which patients will benefit, creating an urgent demand for novel immunotherapy drugs that act through alternative mechanisms. Dr. Spangler is working to develop a class of antibody therapeutics that target cancer-promoting pathways in a different way than all current immunotherapies, with the goal of drastically expanding the percentage of cancer patients who benefit from them.
