Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the safety and efficacy of oral omadacycline as compared to oral nitrofurantoin in the treatment of female adults with cystitis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants were randomized to receive 7 days of treatment of either omadacycline or nitrofurantoin. The End of Treatment visit, Post Therapy Evaluation visit, and Final Follow-up visit was planned within 2 days following the last dose of study drug, on Day 14 (+/- 2 days) after the first dose of study drug, and within 30 to 37 days following the first dose of study drug, respectively. The study followed a double-dummy design. To maintain the study blinding, participants assigned to omadacycline received active omadacycline tablets and over-encapsulated nitrofurantoin placebo tablets. Participants assigned to the nitrofurantoin arm received omadacycline placebo tablets and over-encapsulated active nitrofurantoin capsules.
