VCT at DPHARM 2025: Protecting Subjects, Data, and Trials from Duplicate Subjects In Clinical Trials
We are thrilled to be attending DPHARM 2025: Disruptive Innovations in Philadelphia (Sept 16-17) — to engage with our peers and showcase how our unique technology makes trials safer, more reliable, and more cost-effective. Why Duplicate Subjects and Professional Patients Are a Serious Risk One of the most persistent challenges in clinical research today is

The Top Five Safeguards Against Professional Patients and Duplicate Subjects in Clinical Trials
Clinical trials face an often-overlooked but critical threat: professional patients and duplicate subjects in clinical trials. These individuals move between studies—sometimes across different sponsors, therapeutic areas, or even countries—putting patient safety, data integrity, and trial outcomes at risk. Unfortunately, most traditional methods of protection fall short: These approaches are like putting a band-aid on a

Preventable Failures in GLP-1 and Obesity Clinical Trials: How VCT Protects Against Professional Research Subjects and Duplicate Enrollment
You never want to see a clinical trial fail. The consequences are enormous: And yet, many of these failures are preventable. A recent article highlighted a trial with unusually high discontinuation rates, particularly in the placebo group. Analysts were “puzzled.” I wasn’t. If a participant isn’t losing weight and suspects they’re on placebo, they can

Beyond Their Lane: How Verified Clinical Trials Detects Cross-Therapeutic Duplicate Subjects In Clinical Trials
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

Preventing Professional Subjects At Screening With A Cross-Sponsor Solution- Verified Clinical Trials: From A Research Site Perspective
Ask any seasoned research site team about the toughest protocol criteria to enforce, and you’ll likely hear the same answer: the 30-day washout rule. This requirement — that a subject must not have participated in another trial within the past 30 days — is simple to state but nearly impossible to verify without the right

Eliminating the Professional Patient Problem in Clinical Trials: Why Verified Clinical Trials Is the Global Standard
In today’s competitive and complex research environment, professional patients—individuals who enroll in multiple clinical trials either simultaneously or back-to-back—pose one of the greatest threats to data integrity, subject safety, and trial success. These individuals often participate for financial gain or repeated access to investigational therapies, disregarding protocol requirements such as washout periods or exclusion criteria.
