Rapid and High Patient Recruitment

The cornerstone of CTR’s ability to rapidly recruit clinical research subjects is our large database that has been developed over the last 12 years of more than 8,000 people with a wide variety of cardiovascular, pulmonary, metabolic, gastrointestinal and other diseases. As our program conducts additional studies we are adding patients to our data base regularly. We are able to perform diagnosis and medication searches in our data base for effective patient pre-screening. Dr. Wayne personally pre-screens and recruits many of our patients. Working closely with Dr. Wayne is our full-time recruitment specialist dedicated to patient recruitment and maintaining our data base.

Our site utilizes several methods of additional patient recruitment through effective TV, radio, and print advertising. We work with a professional media company to help us produce high quality and sponsor/IRB approved advertisements. In addition, CTR maintains several high ranking websites that bring potential study patients into ongoing trials and our growing data base. These include our primary website, as well as,,,, and

Thus, through our aggressive patient recruitment measures, we are an excellent enrolling site for our clinical trials.
