Tripled site performance post transition
On-time patient recruitment


Study Characteristics

  • Study Phase: II
  • Study Status: Rescue study

Our Key to Success

    1. To identify the top sites in the right locations (i.e., country)

    2. Years of experience with dermatology sites
      • To focus on the sites most likely to make a difference in recruitment and assure quality data

    3. Site Engagement
      • Use the momentum of activation to quickly bring FPI to each site
      • CRAs in close contact with site throughout the study
