Jason Creasey

Managing Director, Principal Consultant
Maven E&L, UK
Jason Creasey is a graduate analytical chemist. In 2019, he established Maven E&L Ltd, as its Manging Director and Principal Consultant. Maven E&L was setup to provide advice to clients working in the pharmaceutical industry on all aspects relating to the topic of extractables and leachables (E&L) and the risks that leachables pose to the quality and safety of drug products. Prior to this, he worked for GSK where he was the director of their R&D E&L Team.
He has worked in the topic area of E&L since the mid 1990’s on a wide range of modalities and dose forms seeing this area expand and grow in significance for the pharmaceutical and medical device industries. In addition to running his consultancy, he is a scientific advisor to the ELSIE consortium. Since setting up Maven E&L; he continues to present, discuss, and write about E&L. He now publishes a regular E&L blog through LinkedIn and his Website (www.MavenEandL.com), for the exchange of ideas and discussion.
As well as supporting client projects, among recent E&L activity, he is presenting and commenting on risk- based approaches to E&L requirements within the pharmaceutical industry that he hopes will form part of an ICH guidance in the not-too-distant future linked to concepts in leachable risk management as well as looking at analytical uncertainty and how that might be reduced either through better analytical approaches or more collaboration to increase reproducibility and alignment.
