About Verified Clinical Trials

Verified Clinical Trials (VCT) is the global leader — and the only true solution — for detecting and preventing duplicate subjects, professional patients, and other protocol violations in clinical research.

VCT provides sponsors, CROs, and research sites with unparalleled visibility into a research subject’s past clinical trial history — insight that no other system or technology can provide. Without VCT, there is simply no reliable way to evaluate or verify a subject’s prior research participation.

Our global, cross-sponsor registry protects patient safety, data integrity, and study success across all major therapeutic areas. VCT prevents duplicate or overlapping trial participation and ensures that every subject meets protocol-mandated inclusion and exclusion criteria, reducing costly screening failures and improving overall data quality.

With a worldwide presence and dedicated VCT representatives across North America, Europe, Asia-Pacific, and Latin America, we support sponsors and CROs conducting global clinical trials with region-specific expertise and 24/7 support.

Every stakeholder in the research ecosystem — from pharmaceutical and biotechnology companies to CROs and research sites — relies on VCT’s technology, tools, and professional expertise to:

  • Detect and prevent duplicate subjects and protocol violations at the time of screening.

  • Ensure compliance and data accuracy throughout the duration of the trial.

  • Reduce costs and timelines by avoiding ineligible or overlapping participants.

  • Strengthen regulatory confidence and protect against data-quality findings.

Built by experienced clinical research professionals who understand the real-world challenges of trial execution, VCT combines operational simplicity with unmatched global protection.

Operating under the highest international standards of privacy and data protection — including HIPAA, GDPR, and regional equivalents — VCT preserves subject anonymity while maintaining global GCP and ethical requirements.  VCT is used across the globe.

Verified Clinical Trials provides the only proven, global solution to ensure safer participants, cleaner data, and more successful clinical trials — worldwide.
