Bernardo Rapoport, MD and Ronwyn Van Eeden MBChB, FCP(SA) of The Medical Oncology Centre of Rosebank, Johannesburg, South Africa discuss immune-related side effects associated with checkpoint inhibitors. Dr Rapoport says that checkpoint inhibitors have been a major breakthrough in the management of malignant melanoma and non-small cell lung cancer. New checkpoint inhibitors are used to treat triple-negative breast cancer, blood cancer, ovarian and gastric cancer. Dr Van Eededn mentions that it is a new therapy with a different mechanism of action and side effect profile than chemotherapy or targeted therapies. Dr Rapoport and dr Van Eeden talk about anti-CLTA-4 and anti-PD-1 antibody toxicities and point out that the combination of these two antibodies is associated with potentiation of toxicities.
