Duplicate and professional clinical trial participants can endanger themselves and may contribute to failure of an entire study. SubjectRegistry.com provides a single access point to the two largest and most experienced registries of clinical trial subjects. Professional subjects and dual enrollers may then be identified and eliminated to promote patient safety and the success of clinical trials.

CTSdatabase and Verified Clinical Trials each have tens of thousands of subjects in their databases and have been successfully detecting dual enrollers since 2011. Working together as SubjectRegistry.com, investigators and sponsors are provided with the strengths of both systems, a huge database of Phase 1-4 subjects and the greatest chance of detecting dual enrollers .

Once a clinical trial subject is entered on SubjectRegistry.com, investigators are immediately provided with a report detailing any matching subjects or dual enrollment. Sponsors also receive notification of exclusionary matches so that dual enrollers can be identified and removed before randomization.

HIPAA- and 21CFR 11- compliant, both CTSdatabase and Verified Clinical Trials provide environments where subject identity cannot be ascertained. Data is is maintained securely on each database and the privacy of both subjects and sponsors are protected.
