Depression Case Study | Clinical Trials Citruslabs

"Citruslabs' data-driven approach to patient recruitment was a needed change for our site. Our experience with Citruslabs has been phenomenal."

Study Coordinator, Site in Pennsylvania



This Pennsylvania research center was running a clinical study on depression with a very demanding protocol that included very hard inclusion and exclusion criteria.  The site experienced an unusually high screen-failure rate, with a  current enrollment rate of only 2%. To not underachieve, the site urgently needed more qualified patients. 


Citruslabs used its own health apps and also utilized its partner apps to identify suitable candidates based on the site's IRB-approved pre-screener, as well as data points collected through the health apps: 

  • Medical data; 

  • Demographic data;

  • Behavioral data; 


The research center tripled its enrollment rate with Citruslabs and enrolled 5 patients out of 60, which is an overall enrollment rate of 8%. The site's expectation was to enroll 1 out of 60 patients, due to the very demanding protocol. This result provided an immediate and major return of investment to the research center.
