On 18 November 2022, the European Medicines Agency (EMA) published a draft reflection paper (Paper) for public consultation on the criteria for the evaluation of new active substance (NAS) status for biological substances. The Paper provides guidance for applicants on the elements required for a successful NAS claim, including practical examples and a Q&A. This is an area of significant practical importance for pharmaceutical companies and the Paper is a key element to consider during the development of regulatory strategies for biological, biotechnology-derived and advanced therapy medicinal products (ATMPs).
Chemical active substances are excluded from the scope of the Paper, given they are already addressed in two previous reflection papers.

The public consultation on the Paper is open until 31 May 2023.
