What are the two or three critical issues facing the field of cancer immunotherapy?
Immunotherapy has shown impressive efficacy in treating many cancers and the clinical trial responses and commercial approvals of immunomodulatory molecules, antibodies and cell therapies reflect successful translation of laboratory discoveries by many SITC members. However, there are still challenges to address, such as improving efficacy, broadening access, and overcoming resistance mechanisms so more patients can benefit from immunotherapies. For cell therapies, improving access will require scientific innovation to simplify manufacture of autologous products, develop banked allogeneic cells and evaluate new approaches such as in vivo gene therapy to modify immune cells. Research is also needed to understand and overcome mechanisms of resistance to immunotherapies.
An equally important issue is ensuring equitable and affordable access to all patients who may benefit from immunotherapy. This will require innovative regulatory strategies, advocacy for policies that support research, financial coverage and access to immunotherapy, and exploring different care models, such as point-of-care manufacturing for cell therapies.
