          - [Docket No. FDA-2023-N-4965]

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Notice of public workshop; request for comments.

# SUMMARY:

The Food and Drug Administration (FDA or the Agency) is announcing the following public workshop entitled “Advancing the Use of Complex Innovative Designs in Clinical Trials: From Pilot to Practice.” The purpose of the public workshop is to discuss aspects of complex adaptive, Bayesian, and other novel clinical trial designs. This workshop is being conducted to meet the performance goal of convening a public workshop on complex innovative design (CID) included in the seventh authorization of the Prescription Drug User Fee Act (PDUFA VII). The workshop may also inform a draft guidance on the use of Bayesian methodology in clinical trials of drugs and biological products. In conjunction with the workshop, FDA is seeking comments on the use of CID to inform regulatory decision making, including high-level case examples of CIDs and approaches that can advance the use of these designs. The public workshop will be held on March 5, 2024, from 9 a.m. to 3:30 p.m. Eastern Time.

## I. Background

                    This public workshop is intended to meet a performance goal FDA agreed to under the FDA User Fee Reauthorization Act of 2022, in accordance with the PDUFA Reauthorization Performance Goals and Procedures Fiscal Years 2023 Through 2027 letter (PDUFA VII letter), which is available at                     *https://www.fda.gov/​media/​151712/​download.*                     Specifically, section I.4.e of the PDUFA VII letter outlines goals to enhance FDA's capacity to review complex innovative designs and convene a public workshop to discuss aspects of complex adaptive, Bayesian, and other novel clinical trial designs.                

## II. Topics for Discussion at the Public Workshop

                    The purpose of this public workshop is to facilitate discussion on the use of external data sources, Bayesian statistical methods, and simulations in complex innovative trial designs as well as trial implementation (                    *e.g.,*                     examples of defining and mitigating bias when using select trial design methods). Discussion topics will include considerations for external data sources, Bayesian statistical methods, simulations, and clinical trial implementation and will be based on FDA accumulated experience both within and outside of the Complex Innovative Trial Design Meeting Program (                    *https://www.fda.gov/​drugs/​development-resources/​complex-innovative-trial-design-meeting-program*).                

The workshop will consist of two sessions. The first session will focus on case studies that will illustrate various aspects of complex innovative designs and implementation. The second session will consist of panel discussions motivated by the case studies. There will be an opportunity for public comment.

                    Workshop updates, agenda, and background materials (if any) will be made available at                     *https://www.fda.gov/​news-events/​advancing-use-complex-innovative-designs-clinical-trials-pilot-practice-03052024*                     prior to the workshop.
