CenExel, a site network with locations across the U.S., has acquired CTSdatabase, a service that uses a trial participant registry to identify “professional participants,” those patients that attempt to enroll in multiple trials for the money.

In addition to detecting patients who are taking part in multiple trials, CTSdatabase is able to shed light on patients’ trial participation histories, all while keeping their personal information anonymous. Professional participants pose significant problems because they try to join multiple high-paying trials at the same time and give false information to meet inclusion/exclusion criteria, jeopardizing the integrity of trials.

CenExel intends to incorporate the database service throughout its site network to enhance the quality of data in its trials, but it will also leave the door open for other sites, sponsors and CROs to use the service independently.

According to CenExel, trials with subjective endpoints, such as psychiatric or pain trials, are especially impacted by professional participants. The site network claims that approximately 5 to 10 percent of the patients enrolled in central nervous system studies are professional participants.
