Regulatory Stategies for Expidited Drug Approval of Us, Europe and Japan

The increasing demand for rapid access to innovative therapies has driven the development of regulatory strategies that expedite drug approvals while upholding safety and efficacy standards. Regulatory agencies like the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) have introduced expedited pathways, including Fast Track, Breakthrough Therapy, Priority Review, and Accelerated Approval in the U.S., as well as similar programs such as Japan’s Sakigake Designation System and Conditional Early Approval. These initiatives aim to reduce review times and allow patients to access promising treatments sooner, especially for serious and rare conditions. Moreover, adaptive licensing and the incorporation of real-world evidence further improve the approval process’s efficiency. However, while these expedited approvals offer benefits, they also present challenges, including limited data before market entry, the need for post-marketing surveillance, and potential safety issues. This review examines the main regulatory strategies, their effects on drug development, and the need to balance quick access with patient safety.
