MDIC EFS Explorer is an interactive tool designed to increase transparency and operational insight across the U.S. Early Feasibility Study (EFS) landscape. The platform aggregates publicly available clinical trial data to visualize EFS activity by therapeutic area, sponsor, and clinical site.
The intent is to support more informed decision-making by identifying patterns in site participation, geographic concentration, and study volume — ultimately enabling more strategic site selection and broader adoption of EFS best practices.
We welcome your review and feedback on the current version. In particular, we would value input on:
- Usability and clarity of the interface
- Relevance and completeness of data fields and filters
- Additional features or metrics that would increase value
- Any gaps or inaccuracies identified
