In the clinical research world, it’s easy to assume that participants stay in their lane—only enrolling in studies within the same therapeutic area. The reality is far different. Research subjects often cross over between very different indications, creating hidden risks for trial integrity, data quality, and participant safety.
These situations aren’t limited to professional subjects in clinical trials in early-phase studies. In fact, VCT frequently detects participants moving between Phase I trials and vaccine studies—often both relying on healthy volunteers. Sometimes it’s a psychiatric study, other times pain, respiratory, or another unrelated therapeutic area. Regardless of the combination, the risk is the same: protocol violations, confounding safety signals, and compromised data.
The Challenge:
- Many systems are siloed by sponsor or therapeutic area, missing cross-study and cross-sponsor duplication.
- Healthy volunteer trials and early-phase studies are particularly vulnerable.
- Even well-trained sites can’t reliably detect a participant’s undisclosed research history across multiple sponsors.
The VCT Solution:
Verified Clinical Trials is the only global, cross-sponsor, cross-therapeutic research subject database solution that can detect these issues at the time of screening—and continue protection for the entire duration of the trial. With over a decade of organic growth, the VCT database is deeply established, trusted worldwide, and enhanced with biometric capabilities to ensure the highest level of verification.
Sponsors, CROs, and sites using VCT gain:
- Real-time alerts for duplicate and professional subjects across all therapeutic areas.
- Continuous monitoring throughout a study—not just at enrollment.
- Improved subject safety by preventing overlapping trial participation.
- Cleaner, more reliable data by reducing protocol deviations.
In short, no other solution matches Verified Clinical Trials scope, depth, and proven performance. By preventing cross-therapeutic duplication, we protect the integrity of trials across the globe—ensuring that participants truly stay in their lane, and that sponsors can trust their data.
