SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Non-Inferiority Clinical Trials.” The draft guidance includes four parts. The first part is a discussion of regulatory, study design, scientific, and statistical issues associated with the use of non-inferiority studies when these are used to establish the effectiveness of a new drug or therapeutic biologic product. The second part focuses on some of these issues in more detail, notably the quantitative analytical and statistical approaches used to determine the non-inferiority margin for use in NI studies, as well as the advantages and disadvantages of available methods. The third part addresses commonly asked questions about NI studies and provides practical advice about various approaches. The fourth part includes five examples of successful and unsuccessful efforts to define non-inferiority margins and conduct NI studies.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the agency's current thinking on non-inferiority clinical trials.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 statutes and regulations.
