In modern clinical research, competition for eligible subjects is intense, protocols are increasingly complex, and timelines are tighter than ever. Across therapeutic areas, one persistent and costly threat continues to undermine trial integrity: duplicate and professional research subjects.
These are individuals who enroll in multiple studies either at the same time or in rapid succession—often motivated by financial compensation, personal interest in investigational therapies, or both. Their participation can introduce protocol violations, safety risks, and corrupted data that compromise the validity of an entire study.
The Only Solution of Its Kind
For more than a decade, Verified Clinical Trials (VCT) has been the only global, cross-sponsor, cross-therapeutic centralized research subject registry purpose-built to detect and prevent these risks at the time of screening.
There is no other system in the world that offers the same combination of:
- Cross-sponsor visibility — detecting and preventing duplicate subjects in clinical trials across different companies and therapeutic areas
- Real-time subject screening — preventing ineligible subjects before randomization
- Global reach — supporting trials in North America, Europe, Asia, and beyond
- Regulatory compliance — meeting the highest standards of subject privacy and data protection
- Proven track record — trusted by nearly every major pharmaceutical sponsor and leading CRO worldwide
Over a Decade of Trusted Protection
Since our founding, VCT has worked side-by-side with sites, CROs, and sponsors to safeguard:
- Subject safety — preventing exposure to overlapping investigational treatments
- Data quality — reducing placebo response inflation and unreliable endpoints
- Trial timelines and budgets — avoiding costly delays, re-screening, or trial restarts
We’ve applied these protections across all major therapeutic areas, with particular impact in high-risk studies such as obesity, NASH, CNS, vaccine development, dermatology, ophthalmology, and respiratory disease.
Results That Speak for Themselves
Sponsors and CROs using VCT consistently report:
- Cleaner, higher-quality datasets
- Lower screen fail rates due to duplicates
- Fewer protocol deviations
- Greater confidence in trial outcomes
It’s why most of the world’s leading drug developers have chosen to integrate VCT into their clinical operations—and why many now view our protections as a non-negotiable standard for running high-quality trials.
If You’re Not Using VCT, You’re at Risk
With no other comparable solution available, trials that are not protected by Verified Clinical Trials remain vulnerable to avoidable and preventable risks. As subject recruitment grows more competitive and patient pools more interconnected, the cost of not having these safeguards only increases.

Let’s ensure your next trial is protected from day one.
