Regulatory Frameworks in Modern Clinical Trials: Challenges, Gaps, and Future Directions

Clinical trials have undergone substantial transformation over the past decade, driven by innovations such as decentralized trial models, adaptive designs, and the incorporation of real-world data. While these developments have enhanced efficiency and patient accessibility, they have simultaneously introduced complex regulatory challenges. Existing regulatory frameworks often struggle to adequately address these evolving methodologies, particularly in ensuring data integrity, patient safety, and consistent oversight.
This review critically examines the current regulatory landscape governing modern clinical trials, highlighting key challenges and gaps in existing systems. Real-world examples are discussed to illustrate regulatory limitations and practical implications. The paper further explores future directions aimed at strengthening regulatory oversight while maintaining flexibility for innovation. A balanced approach is essential to ensure that advancements in clinical research do not compromise ethical standards or patient safety.
