This document discusses the increasing convergence between medical devices and medicinal products. Some key points: - Medical devices and drugs are increasingly competing to treat the same conditions. Products like companion diagnostics and advanced therapy medical products combine features of drugs and devices. - The legal definitions of drugs, devices, cosmetics and foods are based on binary criteria but the scientific realities exist on a spectrum, making classification difficult. - Borderline cases are challenging the traditional drug/device divide and court decisions emphasize evidence-based classification on a case-by-case basis rather than rigid application of legal definitions. - Unclear boundaries could lead to disputes between regulators and companies over the proper regulatory pathway for innovative products that
