Environmental Risk Assessment of Advanced Therapies Containing Genetically Modified Organisms in the EU

Gene therapy medicinal products have the potential to provide curative treatment for many diseases with current limited therapeutic options. As advanced therapy medicinal products (ATMPs), these therapies undergo a centralised, single European Union authorisation by the European Medicines Agency (EMA), but the risks and potential harm to the environment and population at large are weighted in each application, and different interpretations at national level exist. A streamlined procedure is now in place to facilitate a consistent approach for the assessment of the environmental risks of medicines containing genetically modified organisms for both clinical trial applications and marketing authorisation applications. This article provides an overview of basic requirements across the EU, an overview of the new streamlined process and discusses available guidance for developers with particular emphasis on marketing authorisation applications. All these initiatives are aimed to remove hurdles for ATMP developers and facilitate faster access to patients.
