Because providing clinical research is not a side-business for us; it’s our only business. It’s why we developed and perfected a system unmatched for efficiencies in rapidly screening and enrolling large numbers of study subjects. The benefits to sponsors and CROs are clear: speedier results and greater cost savings.

HIPAA Compliant Database

eStudysite has deployed a revolutionary new method for quickly identifying, screening and enrolling study subjects. As a result, we offer sponsors one of the largest ethnic- and geo-diverse patient databases for a variety of diseases and indications, that, among other functions, links primary care physicians and their patients to our investigative team.

eStudySite leads the industry in making it considerably easier to quickly identify and recruit clinical research patients with the toughest indications. For example, in one study, eStudySite enrolled 24 of the sponsor’s 100 patient goal – at a single hospital site. In another complicated skin study of 1,899 subjects, eStudySite provided 465 (24%) of the patients enrolled worldwide. We also pre-bank up to 50% of our patient goal before beginning a central nervous system study (CNS).

Our patented database of hundreds of thousands of patients, along with the software program we developed to quickly identify subjects that meet exact study requirements, allows us to routinely provide larger and faster enrollments. It is the most efficient and effective system currently available, and it significantly reduces time and costs.

With the number of successful clinical trials completed and dozens more underway, eStudySite can deliver the required number of study participants faster and more efficiently, with a track record of exceeding enrollment goals.
