The primary concern of FDA was the dose-related post-dose decreases in forced expiratory volume in one second, or FEV1 observed by the FDA based on the decrease in FEV1 recorded in the Company’s subjects who were administered with placebo versions of AZ-004.
The Company after presented evidence that the placebo device is safe by showing the changes seen was likely background events in the population studied and that the aerosol characterization does not indicate a basis for concern, was asked by the FDA to provide its arguments in the AZ-004 NDA resubmission.
