EU Regulatory Pathways for ATMPs: Standard Accelerated and Adaptive Pathways to Marketing Authorisation

摘要

Advanced therapy medicinal products (ATMPs) require evaluation by the European Medicines Agency’s Committee for Advanced Therapies prior to being placed on the European market, subject to a Marketing Authorisation granted by the European Commission. In common with other medicinal products, various regulatory pathways are available for taking ATMPs through clinical trials to market authorisation, and the regulatory pathway taken will depend on a product’s characteristics and the target patient population. With the industry poised to deliver more late-stage clinical and commercial ATMPs for serious diseases with high unmet medical need (e.g., T cell immunotherapies for cancer), bringing medicines to patients through optimized regulatory strategies and expedited pathways is assuming greater importance. The European Medicines Agency’s priority medicines (PRIME) scheme was introduced in 2016 specifically to enable this, and eligibility has been granted to 19 ATMPs as of the fourth quarter (Q4) 2018. Furthermore, two chimeric antigen receptor (CAR) T cell therapies, Yescarta and Kymriah, have recently completed their journeys through the scheme to Marketing Authorisation. This review discusses how the regulatory pathway for any particular ATMP, with or without PRIME designation, is determined and navigated.
