Non-inferiority Trials: Practical Issues and Current Regulatory Perspectives
This webinar will examine and highlight differences among non-inferiority (NI) trials, equivalence, and
superiority study objectives and designs. It will also review current FDA guidance for NI clinical
Why Should You Attend:
Basic non-inferiority (NI) clinical study designs appear to provide a straight-forward approach for
evaluating whether a new drug or medical device is an appropriate substitute or replacement for a
current standard treatment. In these studies the typical comparison is between a new drug and an
active control with the goal of demonstrating that the new drug is “not inferior” to the standard
treatment by “too large” a margin. Traditional approaches to demonstrating NI of a new drug
amounted to a simple acceptance of the null hypothesis of no difference between that drug and an
active control, but these are currently recognized as inadequate to support a claim of NI.
This webinar will examine the philosophy and assumptions underlying NI trials by highlighting the
differences among NI, equivalence, and superiority trials with regard to basic clinical study designs
and appropriate hypothesis tests, power and sample size, and conceptual and statistical analysis
differences. We will conclude with a review of current FDA guidance for NI clinical studies.
Areas Covered in the Seminar:
Description and comparison of NI, equivalence, and superiority study objectives and designs.
Zeroing in on the specific clinical question to be asked.
Decision tree for choosing the appropriate design to answer the specific clinical question.
Why assay sensitivity matters and what you can do to maximize it.
How to determine the appropriate or acceptable “margin” of inferiority.
Appropriate hypothesis tests and statistical interpretation. (for non-statisticians).
