Immunotherapy has become an increasingly appealing therapeutic strategy for patients with cancer, with many late-stage clinical trials demonstrating overall survival (OS) advantages in melanoma and castrationresistant prostate cancer. More recently, non-small cell lung cancer (NSCLC) has become a focus for the next generation of immune-based therapeutic strategies. Immunotherapy, in particular the use of monoclonal antibodies that block inhibitory immune checkpoint molecules and therefore enhance the immune response to tumors, has shown clinical promise in advanced solid tumors. The clinical rationale for targeting the PD-1/PD-L1 pathways will be reviewed in this supplement, including a comprehensive review of selected ongoing clinical trials to evaluate the potential of targeting immunotherapy in cancer drug development. Emerging clinical data discussed in this supplement suggest that targeting immunotherapy in cancer will become an integral part of the clinical management strategy for solid tumors.
Cancer is traditionally treated with either conventional therapy (ie, chemotherapy or radiation therapy) or targeted drugs that directly kill tumor cells. While the number of patients who survive cancer has seen significant increases, the “war” rages on.1
