This guidance outlines FDA's current thinking on the use of Bayesian statistical methods in medical device clinical trials. Bayesian statistical methods are currently used in a variety of medical device applications to FDA. This guidance includes a general description of Bayesian methods, discussions on design and analysis of Bayesian medical device clinical trials, the benefits and difficulties with the Bayesian approach, and comparisons with standard (frequentist) statistical methods. Additionally, some ideas on Start Printed Page 6210using Bayesian methods in post-market studies are presented.
The draft version of this document was issued on May 23, 2006, for comment. A public meeting to discuss the document was held on July 27, 2006. FDA received several hundred specific comments on the guidance. There were many comments of a specific technical nature; for example, a set of comments regarding our discussion of prior distributions, the meaning of “non-informative” priors, and how we might evaluate the choice of a prior led us to make some changes and additions to the document. As another example, the central importance of the concept of “exchangeability” was revealed in some of the comments and has recently become more apparent; thus the discussion of exchangeability has been greatly expanded. Many comments of a more regulatory nature (e.g. specific issues regarding implementation of Bayesian methods in a regulatory setting) were also addressed in the revision. To the extent possible, editorial comments regarding the presentation of the statistical or technical issues and/or the writing were addressed.
II. Significance of Guidance
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the agency's current thinking on “Guidance for the Use of Bayesian Statistics in Medical Device Clinical Trials.” It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute and regulations.
