Summary of the EMA Joint Regulators/Industry QbD workshop (London, UK; 28-29 January 2014)

Abstract

This paper summarises the discussions and insights gained from the key themes that emerged during the Quality by Design (QbD) Workshop held at the European Medicines Agency offices in London, UK, on 28-29 January 2014. Industry and regulators shared practical experiences from 6 case studies (5 approved small molecule products and one phase 3 biotechnological product) based on QbD submissions by 5 companies (AstraZeneca, GlaxoSmithKline, Novartis, NovoNordisk and Pfizer). The case studies covered a range of different development, regulatory submission and post-approval aspects of QbD, and were developed through confidential discussions between the company representatives and regulators. Key themes that emerged from the workshop discussions were: 1. Presentation of Information in Submissions (Development story and the presentation of information in Marketing Authorisation Applications; Risk assessment and criticality); 2. Development Aspects (Design space; Use of models; Control strategy); and 3. Post Approval Aspects (Lifecycle management; Dossier - Quality System interactions; Handling of Deviations). Many aspects of QbD for biotechnological products are similar to small molecules, but there are some important differences highlighted in this paper. The final section of the paper discusses some proposals for future developments to address the issues that were identified.
