We propose an “efficacy-to-effectiveness” (E2E) clinical trial design, in which an effectiveness trial would commence seamlessly upon completion of the efficacy trial. Efficacy trials use inclusion/exclusion criteria to produce relatively homogeneous samples of participants with the target condition, conducted in settings that foster adherence to rigorous clinical protocols. Effectiveness trials use inclusion/exclusion criteria that generate heterogeneous samples that are more similar to the general patient spectrum, conducted in more varied settings, with protocols that approximate typical clinical care. In E2E trials, results from the efficacy trial component would be used to design the effectiveness trial component, to confirm and/or discern associations between clinical characteristics and treatment effects in typical care, and potentially to test new hypotheses. An E2E approach may improve the evidentiary basis for selecting treatments, expand understanding of the effectiveness of treatments in subgroups with particular clinical features, and foster incorporation of effectiveness information into regulatory processes.

This article describes recent developments in licensing and reimbursement policies in the EU, US, and Japan, examines causes of changes and compares differences and projects trends. With respect to licensing, the European Medicines Agency (EMA), US Food and Drug Administration (FDA), and Japan's Pharmaceuticals and Medical Devices Agency (PMDA) are committed to rigorous evaluation of pharmaceuticals in advance of market access with feedback from postmarket experience. The EMA is exploring integrated adaptive pathways for licensing, with formal pilot tests to provide a practical proof of concept. The FDA is augmenting traditional licensing procedures through reforms including Breakthrough Product Designation. The PMDA is implementing reforms to foster innovation and earlier patient access through its Sakigake strategy and licensing reforms on regenerative medicines. With respect to reimbursement, several generalizations emerge. Relative to US counterparts, EU payers typically set higher standards for evidence of effectiveness as a condition of reimbursement, impose tougher limits on reimbursement by indication, and drive harder deals in negotiations over prices.
