Nevertheless, the publication rates of sponsor-submitted trial results for drugs approved by the FDA have been low, and discrepancies exist between original trial data submitted to the FDA and data found in published trials. In this context, the peer-reviewed medical literature has a powerful and important role in disseminating information relevant to both clinicians and the public. These documents contain detailed efficacy and safety data that are relevant to drug approval but are not necessarily intended to be shared with general evidence users such as clinicians, patients, and policymakers. Once the drug is approved, the FDA produces a ‘Summary Basis of Approval’ document that contains synopses and evaluations of clinical data and statistical analyses performed by FDA medical officers during the approval process. Sponsors of a new drug are required to submit all data to the FDA, including complete protocols, protocol revisions, and data from successful and failed trials.
Their efficacies are demonstrated by prolonging patients’ survival and improving their quality of life by preventing or ameliorating cancer-related symptoms. Īnticancer drugs are approved by the FDA based on substantial evidence of clinical benefit from adequate and well-controlled clinical trials. These findings have prompted the search for next-generation ICPis as well as evaluations of their combinations with other biologic agents. The notable successes of these pivotal trials may have led to unrealistically high expectations among patients and clinicians, as more recent studies have shown that only a subset of patients exhibit durable responses, and existing checkpoint-blocking monotherapies seldom lead to complete remission. Pembrolizumab and nivolumab were the first ICPis that target programmed cell death protein 1 they showed high response rates with favourable toxicity profiles and were approved for treating metastatic melanoma in 2014. The first ICPi approved by the United States Food and Drug Administration (FDA) was ipilimumab, a fully humanized immunoglobulin G1 monoclonal antibody that blocks cytotoxic T-lymphocyte antigen. More recently, ‘immunotherapy’ agents that rely on immunomodulatory mechanisms to target and destroy cancer cells, most notably immune checkpoint inhibitors (ICPis), have been developed. Anticancer agents developed over the last 2 decades utilize multiple mechanisms of action including conventional cytotoxic agents as well as inhibition of oncogenic signalling pathways and angiogenesis. An improved understanding of the biology of cancer has led to remarkable progress in therapeutic approaches.
