Verified Clinical Trials (VCT), the world’s largest research subject database registry, has expanded operations in Japan through a collaboration with Medical Revolutions Japan (MRJ) and the Japan Association of Contract Institutes for Clinical Pharmacology (JACIC). This partnership helps address the growing global challenge of duplicate subjects in clinical trials and professional patients, which can undermine data integrity, increase risks, and add significant costs to clinical research.
For decades, Japan has relied on local systems to help prevent duplicate subject enrollment, primarily in Phase I trials. However, with the increasing complexity of global research and the rise of multi-phase and multi-sponsor studies, modernized protections are needed to safeguard later-phase trials as well. Verified Clinical Trials now provides a proven, secure, biometric-enabled platform that prevents duplicate and professional subjects at the time of screening — and continues these protections for the entire duration of the study.
With the support of MRJ and JACIC, as well as leading research sites across Japan, this collaboration demonstrates a strong commitment to achieving the highest standards of subject protection, data quality, and regulatory compliance. These respected organizations and sites are doing their part to achieve excellence and safety in their clinical trials by utilizing Verified Clinical Trials.
While VCT has already supported trials in Japan through global programs, this expanded rollout will dramatically increase our presence in the region. Multiple sites have already begun implementation, with additional Phase I through Phase IV sites expected to join in the coming weeks and months.
Why Preventing Duplicate and Professional Patients Matters
Duplicate subjects and professional research patients remain one of the most overlooked risks in clinical trials. They threaten trial accuracy, inflate placebo response, and compromise participant safety. VCT’s cross-sponsor, cross-therapeutic area subject registry detects and blocks ineligible subjects at screening — protecting studies before issues arise.
By adding subject verification as a standard line item in trial budgets, sponsors gain a cost-effective safeguard that supports better outcomes and stronger regulatory confidence.
