Research Sites Cooperate To Prevent Duplicate Subjects in CNS Clinical Trials By Using The Verified Clinical Trials Research Subject Registry

Duplicate subjects exist in most clinical trials to varying degrees.  CNS clinical trials are especially  prone to duplicate subject or over enrollment.  The issue exists from phase 1 healthy volunteer studies to multiple phase 2/3 clinical trials across many therapeutic indications.  Use of global research subject database registry such as Verified Clinical Trials will help …

Professional Research Subjects Travel: Prevent Duplicate Subjects In Your Clinical Trials With Verified Clinical Trials

Mature data collected from North America as well as in Europe demonstrates how research volunteers will travel large distances to screen or enroll contemporaneously in multiple clinical trials as duplicate subjects in clinical trials. The numbers are significant and occur across both early and later phase studies. Why risk these safety and data quality issues? …

Preventing Duplicate Subjects In European Clinical Trials: Average Travel Distance

Verified Clinical Trials (VCT) has been well adopted in many research sites and CROs in several European countries.  Data again proves that research volunteers will travel significant distances to dual enroll in multiple clinical trials contemporaneously. There is a similar experience in the United States whereby duplicate subjects in clinical trials will travel thousands of …

CNS Clinical Trials Are Prone To Duplicate Subjects and Duplicate Enrollment

CNS clinical trials, especially psychiatry clinical trials are prone to having duplicate subjects in clinical trials.  In studies that rely upon subjective end points, there exists the ability to provide false information in an effort to gain entry in to the study.  Of course, these occurrences result in failed trials due to elevated placebo rates or issues with safety if the volunteer does in fact take the investigational product (IP) from multiple sites.

Use of the Verified Clinical Trials (VCT) global research subject registry has been quite effective at stopping these issues at the time of screening. The protections continue throughout the entire study.  The Verified Clinical Trials network is expansive and covers multiple countries worldwide.  Nearly every phase 1 unit across the United States and now in Europe and elsewhere.  VCT protects many therapeutic indications but is especially focused on duplicate subjects in CNS clinical trials and duplicate subjects in psychiatry clinical trials.

The data is rather impressive with as preventable protocol violations including duplicate or dual enrollment in clinical trials ranging higher than 10% in some instances.  The National Institute of Health (NIH) uses VCT exclusively.

Duplicate Subjects In Your Clinical Trials Result In Safety & Data Quality Issues

To maintain data integrity and safety, it is necessary to highlight and detect duplicate subjects in your clinical trials proactively.  This is true for nearly all therapeutic indications and all phases of clinical trials research.  Duplicate enrollment (over enrollment) is NOT just a healthy volunteer phase 1 issue.  The global research subject database registry VCT data over the …
