Trial Logistics in the Patient's Palm

According to CISCRP, traveling to the study clinic is the top burden cited by trial participants. Greenphire enables sponsors and CROs to remove logistical obstacles, and now GreenSpace provides 24/7 access, putting the patient in control, eliminating stress and increasing convenience. 

  • Visit and Travel Details: ensures successful and timely visits with participant views into visit prep and travel itineraries

Is it time to start rethinking mobile clinical trial apps?

“Sponsors and sites should aspire to offer participants a digital companion that supports all parts of the trial, from identifying and enrolling in a trial, accessing relevant and helpful resources, recording information in real time, having a view into site visits and/or travel itineraries, receiving reminders, and providing an easy way to track and manage reimbursements and/or stipends.”
