The 2023 Decentralized Trials & Research Alliance Summit (DTRA) marked a significant juncture in clinical research, particularly through its panel discussion on Decentralized Clinical Trials (DCTs). This panel, comprised of esteemed U.S. government figures like Gina Conenello from BARDA, Christopher Hartshorn at NIH, Stephen Konya at the Office of the National Coordinator for Health IT, Timil Patel at FDA, and Anindita Saha at FDA’s Digital Health Center of Excellence, and moderated by DTRA Co-Founder Craig Lipset, delved into the complex challenges facing DCTs. The conversation illuminated various obstacles, such as technological integration, regulatory frameworks, patient accessibility, and data security, highlighting the hurdles that need to be overcome to fully harness the transformative potential of DCTs.

Evolving Regulatory Frameworks for DCTs

The discussion’s significant focus was the need for regulatory frameworks to adapt to the unique demands of DCTs. Panelists emphasized that current FDA regulations and guidance designed for conventional trials must evolve to encompass the nuances of decentralized methodologies. This includes establishing guidelines for remote monitoring, data collection, and applying digital health technologies in clinical trials.

Ensuring Data Integrity and Quality

Ensuring the integrity and quality of data in DCTs emerged as a paramount challenge. In DCTs, data is often collected remotely and through digital platforms, raising concerns about reliability and accuracy. Panelists discussed the need for stringent protocols and standards to ensure data quality, emphasizing robust validation methods and real-time data verification processes.

Addressing Patient Privacy and Data Security

With DCTs relying heavily on digital platforms for data collection, protecting patient privacy and securing data is crucial. Panelists highlighted the importance of stringent data protection measures and compliance with privacy laws like HIPAA. The challenge lies in developing secure data transmission channels and storage systems while making them accessible to trial participants.

Navigating Ethical Considerations

Ethical considerations were a key focus, particularly around informed consent in a remote setting. Panelists noted the challenges in ensuring participants fully understand and consent to trial procedures in a decentralized model. Developing clear, accessible, and understandable consent processes was crucial in addressing this challenge.

Building Adequate Technology and Infrastructure

The panelists discussed the necessity for appropriate technology and infrastructure to support DCTs. Challenges include ensuring consistent internet connectivity, addressing participants’ digital literacy, and providing necessary devices for remote participation. Solutions need to be equitable and accessible to all potential participants, regardless of their location or technological capabilities.

Enhancing Participant Engagement and Retention

Maintaining participant engagement and retention in a decentralized environment is challenging due to the reduced or absent face-to-face interactions. The panelists explored strategies to keep participants engaged, such as effective communication, continuous support, and regular follow-up.

Interoperability and Standardization

Interoperability and standardization across different platforms and systems used in DCTs were identified as critical challenges. Ensuring seamless data integration and analysis across various trials and systems is crucial for the overall success and reliability of DCTs.


The DTRA panel highlighted the multifaceted challenges associated with DCTs and the ongoing efforts by U.S. government agencies to address these issues. These discussions reflect a commitment to advancing DCTs as an integral and effective part of clinical research. The insights provided by the panelists underscore the need for collaborative efforts across regulatory bodies, technology providers, and healthcare professionals to overcome these challenges and harness the full potential of decentralized clinical trials.
