In the course of development of an antimicrobial agent,
the manufacturer will conduct clinical studies that will yield a
large volume of data. Optimally, the design and evaluation of
studies should conform to the most recent guidelines of ESC-
MID and IDSA. The manufacturer must provide, in a summarized fashion, all relevant data needed to make breakpoint
determinations. The manufacturer should note if the data are
different from those submitted to regulatory authorities, and
give reasons for the differences.
