Summary
Compiles FDA expedited program precedents, designation request strategies, and acceptance criteria analysis to support Breakthrough Therapy and Fast Track applications.
Detailed Description
The Breakthrough/Fast Track Evidence Pack helps sponsors prepare compelling requests for FDA expedited program designations. It analyzes historical Breakthrough Therapy Designation (BTD), Fast Track Designation (FTD), and Priority Review precedents to identify the evidentiary thresholds and presentation strategies associated with successful applications.
The pack evaluates your clinical data against the statutory and practical criteria for each expedited program, benchmarking your results against approved designations in the same therapeutic area. It identifies the strength and weaknesses of your current evidence package and recommends strategies to address gaps.
Deliverables include an expedited designation feasibility assessment, a designation request template pre-populated with precedent-informed content, and a comparative analysis of successful and unsuccessful designation requests in your indication.
