For sponsors and CROs

Assess patient availability at sites earlier.

Emtrial structures inclusion and exclusion criteria from the study protocol. Research sites assess them against approved clinical data and release an aggregate response for the sponsor or CRO.

A clear answer without patient data.

Every response shows the available patient population, the criteria used, open assumptions, and the clinical data sources included in the assessment. The site approves the aggregate information before it is shared.

Patient-level data stays inside the hospital.

The local study team reviews potential matches. Sponsors and CROs receive only aggregate information approved by the research site.

Hospital-controlled environment

Stays inside the hospital

  • Patient records from approved clinical sources
  • Individual matching results
  • Supporting information and study-team decisions
Limited external view

May leave after hospital approval

  • Site-approved cohort information
  • Open questions and assessment scope
  • No patient records or individual matching results

Only aggregate information approved by the research site crosses this boundary.

Make the next site decision with better data.

A structured response shows whether the target population is present, which criteria the available data supports, and where uncertainty remains. Patient-level records never become part of the sponsor view.

Delay becomes cost.

Recruitment problems affect timelines, budgets, and planned study duration. These published figures describe the cited trials, not Emtrial performance.
