Preventable Failures in GLP-1 and Obesity Clinical Trials: How VCT Protects Against Professional Research Subjects and Duplicate Enrollment

by

You never want to see a clinical trial fail. The consequences are enormous:

  • Millions (sometimes billions) wasted
  • Years of delays
  • Life-saving therapies withheld from patients who need them most

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 simply jump to one of the dozens of other studies targeting the exact same population. This phenomenon isn’t new — it’s the reality of professional research subjects in clinical trials. Participants who “shop” for studies or conceal their participation history create enormous risks.

This is exactly where Verified Clinical Trials (VCT) makes the difference.

VCT: The Insurance Policy That Pays for Itself

Think of VCT as a low-cost insurance policy with one of the highest ROIs in the industry. By ensuring you’re enrolling the most eligible participants possible, VCT saves time, prevents unnecessary costs, and protects against failure.

Here’s how:

  1. Confirming enrollment status – VCT confirms that the participant you’re enrolling isn’t already bouncing between trials.
  2. Blocking duplicate subjects in clinical trials – VCT prevents a participant in Study 1 from slipping into Study 2.

The results are measurable:

  • Lower discontinuation and dropout rates
  • Improved medication and eDiary adherence
  • Reduced placebo response
  • Stronger efficacy signals
  • Higher data quality and integrity

The Cost of Prevention vs. The Cost of Failure

Clinical trials are already complex and expensive. Adding preventable risks like duplicate subjects or professional research subjects only compounds the problem.

With VCT, sponsors and CROs invest in prevention — and the ROI is undeniable. A small upfront cost translates into millions saved in downstream expenses, faster timelines, and greater confidence in trial outcomes.

Simply put: VCT doesn’t just save money — it can prevent your clinical trial from failure.

Let’s Work Together

Clinical trials are hard enough. Let’s not let preventable risks derail them. By partnering with Verified Clinical Trials, you’re not only protecting your investment — you’re protecting patients, data integrity, and ultimately the future of medicine.
