Complex Innovative Trial Designs Pilot Program

As displayed in the Federal Register notice on August 29, 2018, FDA is conducting a Complex Innovative Trial Design (CID) Pilot Meeting Program to support the goal of facilitating and advancing the use of complex adaptive, Bayesian, and other novel clinical trial designs. The CID Pilot Meeting Program fulfills a performance goal agreed to under PDUFA VI, included as part of the FDA Reauthorization Act of 2017.

This pilot meeting program offers sponsors whose meeting requests are granted the opportunity for increased interaction  with FDA staff to discuss their proposed  CID approach.

Meetings will be conducted by FDA’s Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER) during fiscal years 2019 to 2022. To promote innovation in this area, trial designs developed through the pilot meeting program may be presented by FDA (e.g., in a guidance or public workshop) as case studies, including trial designs for medical products  that have not yet been approved by FDA.

Goals of the CID Pilot Meeting Program

The CID Pilot Program is designed to:

  • Facilitate the use of CID approaches in late-stage drug development.
  • Promote innovation by allowing FDA to publicly discuss the trial designs considered through the pilot program, including trial designs for medical products that have not yet been approved by FDA.
