Guide on Non-inferiority Trials for Antibacterials
Federal Register notice: FDA is making available a draft guidance entitled “Antibacterial Therapies for Patients with an Unmet Medical Need for the Treatment of Serious Bacterial Diseases — Questions and Answers (Revision 1).” The document is intended to provide necessary updates to the final guidance entitled “Antibacterial Therapies for Patients With an Unmet Medical Need for the Treatment of Serious Bacterial Diseases” released 8/2017. It explains FDA’s current thinking about possible development programs and clinical trial designs for antibacterial drugs to treat serious bacterial diseases in patients with an unmet medical need. Since the 2017 final guidance was issued, there have been a few new drugs approved that have activity against certain drug-resistant organisms. Therefore, FDA says, it is now possible to conduct noninferiority (NI) trials that include subjects with infections caused by certain drug-resistant organisms because an effective active control can be provided. Additionally, more details are provided for the currently used NI trial designs that may be used with a wider NI margin, including cases in which the trial population is enriched for subjects with infections caused by certain drug-resistant organisms.
