Recommendations for the design and implementation of an Early Feasibility Studies program for medical devices in the European Union

Early Feasibility Studies (EFS) are among the pre-market clinical investigations allowed by the International Standard for Clinical investigation of medical devices (MD) for human subjects. The Food and Drug Administration (FDA) introduced an EFS program in the US in 2013. The European Union (EU) MD Regulation, that entered into force in May 2021, opened the possibility of EFS in the EU. However, European countries at present have no standardized procedural framework for EFS. In this paper, we address the desirability of a European EFS program.
