Clinical Trial Challenges

Clinical trials are expensive and challenging in ordinary times. COVID-19 has made this situation much more difficult, negatively impacting clinical trial activities and delaying life-saving treatments. In response, the FDA has acted recently to create an environment to encourages novel trial designs where external control arms can thrive.

In-Depth, Regulatory-Grade RWD and Scientific Expertise

  • Inform clinical trial design and feasibility with our interactive cohort matching tool
  • Conduct propensity score matching or frequency matching with demographic and clinical characteristics matched to clinical trial patients
  • Rescue underperforming trials when the RCT is having difficultly accruing patients in a standard of care cohort
  • Satisfy market requirements for fast-tracked, breakthrough applications or newly approved treatments coming to market with limited comparative data
  • Fulfill post-authorization safety assessments, surveillance, and/or efficacy evaluations required by regulators
  • Conduct studies for label expansion and new indications
  • Find new dosing schedules and routes of administration
  • Dynamically track the ECA cohort from diagnosis through discharge, end of record, or death
  • Generate persuasive comparative evidence to demonstrate product value

Novel Study Designs

External control arms use real-world data (RWD) to enhance data from single-arm trials. They can speed up patient accrual and reduce costs. Results include:

  • 50% reduction in patient accrual needs
  • Ability meet fast-tracked designation timelines
  • Increased trial efficiency
  • Reduced site and patient burden
  • Decreased risk
