Cost-effectiveness analyses of targeted therapy and immunotherapy for advanced non-small cell lung cancer in the United States: a systematic review.

Introduction: Mutation-targeting and immuno-oncology drugs are revolutionizing the treatment of advanced non-small cell lung cancer (NSCLC). Cost-effectiveness analyses (CEA) of these drugs have been conducted using various analytical methods and cost-effectiveness thresholds. This systematic review provides a comprehensive summary of the available evidence.Area covered: PubMed, Embase, and Cochrane Library were used to select for CEA of targeted therapies for NSCLC in the United States published between 2008 and 2020. Among the 28 included studies, a majority were published from 2017 to 2020 (n = 18) and more than half targeted non-squamous NSCLC (n = 15). The most frequently evaluated therapy was pembrolizumab (n = 11), followed by bevacizumab (n = 8) and erlotinib (n = 4). After 2009, all included studies applied $100,000 or more thresholds. Thresholds of studies supported by industry (median = $150,000) were more distributed than those of studies supported by nonprofits (median = $100,000).Expert commentary: Medications of interest have changed and are individualized to particular mutations. The cost-effectiveness thresholds varied among sponsors but generally trended to increase over time. This review provides an overview of the available cost-effectiveness findings for stakeholders and contributes to evidence-based practice.
