Regulatory Aspects for Approval of Advanced Therapy Medicinal Products in the EU.

Abstract

In the European Union (EU), advanced therapy medicinal products (ATMPs) undergo evaluation by the European Medicines Agency's (EMA) Committee for Advanced Therapies (CAT) to obtain marketing authorization under the centralized procedure. Because of the diversity and complexity of ATMPs, a tailored approach to the regulatory process is required that needs to ensure the safety and efficacy of each product. Since ATMPs often target serious diseases with unmet medical need, the industry and authorities are interested in providing treatment to patients in a timely manner through optimized and expedited regulatory pathways. EU legislators and regulators have implemented various instruments to support the development and authorization of innovative medicines by offering scientific guidance at early stages, incentives for small developers and products for rare diseases, accelerated evaluation of marketing authorization applications, different types of marketing authorizations, and tailored programs for medicinal products with the orphan drug designation (ODD) and the Priority Medicines (PRIME) scheme. Since the regulatory framework for ATMPs was established, 20 products have been licenced, 15 with orphan drug designation, and 7 supported by PRIME. This chapter discusses the specific regulatory framework for ATMPs in the EU and highlights previous successes and remaining challenges.
