In the world of clinical research, ensuring participant safety and preserving data integrity are not just goals—they are regulatory and scientific necessities. Yet, a significant blind spot persists in the industry: duplicate subjects in clinical trials and professional research subjects continue to slip through the cracks, threatening the quality of clinical trials globally.
Verified Clinical Trials (VCT) was created to solve exactly this problem. And more than a decade later, no other solution comes close.
A One-of-a-Kind Global Research Subject Database
VCT operates the only cross-sponsor, cross-therapeutic area Research Subject Database designed specifically to detect and prevent duplicate subjects and professional trial participants. The size of the VCT database is unparalleled—orders of magnitude larger than any alternative solution or site-level tool.
This scale matters. With hundreds of sponsors, CROs, and research sites contributing data across the globe, VCT’s registry captures subject activity across a wide range of indications and geographies, enabling real-time detection of potential protocol violations before subjects are enrolled.
Protection at Screening—And Beyond
Unlike other point-in-time checks, VCT protects trials from start to finish. Our technology screens participants at the time of enrollment and continues to monitor throughout the life of the study—identifying overlapping studies, washout violations, and other enrollment risks in real time.
This continuous protection means that your trial doesn’t just start strong—it stays compliant and scientifically sound.
The Only ISO 27001-Certified Subject Registry
Verified Clinical Trials is proud to be the only research subject registry ISO 27001 certified, ensuring the highest global standard in data security and privacy. Our commitment to compliance and information security sets us apart and provides sponsors and sites with unmatched confidence in the integrity of their subject data.

Filling a Critical Gap in Clinical Research
Most trials still lack the ability to evaluate a participant’s past research history—a glaring gap that VCT fills. As trial complexity increases and populations overlap across studies, especially in high-demand areas like CNS and obesity, the risk of duplicate and professional subjects has only grown. VCT addresses this unmet need with a global, scalable, and proven solution.
For further insights into the challenges posed by duplicate participants in clinical trials, consider reading How to Avoid The Dangers of Duplicate Participants in Clinical Trials by Moe Alsumidaie. Additionally, the study Strategies to exclude subjects who conceal and fabricate information when enrolling in clinical trials offers valuable strategies for mitigating risks associated with professional subjects.
Bottom line: Verified Clinical Trials is the only comprehensive, cross-sponsor registry solution for clinical trials research. No other company offers the size, scale, experience, or regulatory rigor to match what VCT delivers.
If you’re serious about protecting your data and your subjects, there’s only one place to start: Verified Clinical Trials.
