REGULATORY CHALLENGES IN APPROVAL OF MEDICAL DEVICES IN ICH AND SELECTED COUNTRIES: A COMPREHENSIVE REVIEW FOR BETTER REGULATORY DELIVERY

The rapid advancement of medical device technologies, including implantable devices, digital health solutions, combination products, and artificial intelligence-based medical technologies, has increased the complexity of regulatory approval processes worldwide. Effective regulatory delivery requires harmonized frameworks that ensure patient safety, product quality, clinical effectiveness, and timely market access. This review explores the regulatory challenges associated with the approval of medical devices across International Council for Harmonisation (ICH)-aligned regions and selected countries, including the United States, European Union, Japan, India, and other emerging markets. The article highlights key challenges such as differences in classification systems, clinical evaluation requirements, quality management system expectations, technical documentation formats, post-market surveillance obligations, and variations in regulatory pathways. While regulatory frameworks such as the US FDA Medical Device Regulations, European Medical Device Regulation (EU MDR 2017/745), Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) requirements, and India’s Medical Device Rules (MDR) 2017 aim to strengthen oversight, inconsistencies among jurisdictions continue to create barriers for manufacturers seeking global approval. The review further discusses challenges related to risk-based classification, cybersecurity requirements for connected devices, artificial intelligence-based medical devices, real-world evidence generation, conformity assessment procedures, and regulatory resource limitations in developing countries. Strategies for improving regulatory delivery, including international harmonization, reliance pathways, regulatory convergence, digital submission platforms, capacity building, and enhanced collaboration among regulatory authorities, are emphasized. A coordinated global regulatory approach can reduce duplication, accelerate access to innovative medical devices, and maintain high standards of safety and performance. This comprehensive review provides insights into current regulatory gaps and proposes opportunities for achieving efficient, transparent, and patient-centric medical device approval systems worldwide.
