July 2017: Dr. Stephen Thein will be presenting a poster titled “Evaluation of Rapid, on-Site APOE Genetic Testing for Subject Outreach and Trial Recruitment” at the AAIC conference in London, England on Wednesday, July, 19th at 1pm.

May, 2017: Pacific Research Network has continued to expand over the past year. PRN’s strong presence in the community through participation in charity walks, health fairs, social media campaigns, educational symposiums and screening days has contributed to higher enrollment in its Alzheimer’s, sleep and MS trials. The site has expanded its satellite site; located just 20 miles from the main site and serving a predominantly elderly population in a well-known retirement community. The satellite is now equipped with two rooms used for inpatient and sleep trials. The certified sleep labs (both at the main site and now, satellite) continue to operate seven days per week. Collectively, these efforts have resulted in an increase in the volume of clinical trials contracted and the amount of subjects ultimately randomized.
