The purpose of this guidance is to assist sponsors in the clinical development of drugs for the treatment of uncomplicated urinary tract infections (uUTIs). Specifically, this guidance addresses the Food and Drug Administration’s (FDA’s) current thinking regarding the overall development program and clinical trial designs for drugs to support an indication for the treatment of uUTIs.

We consider the treatment of uUTIs to be an indication distinct from the treatment of complicated urinary tract infections (cUTIs). This guidance addresses uUTIs only. The FDA issued a separate guidance on cUTIs. This guidance does not contain discussion of the general issues of statistical analysis or clinical trial design. Those topics are addressed in the ICH guidances for industry E9 Statistical Principles for Clinical Trials (September 1998) and E10 Choice of Control Group and Related Issues in Clinical Trials (May 2001), respectively.
