An Open-Label, Randomized, Multi-Center Study to Evaluate the Efficacy and Safety of a Single Dose of Oral Solithromycin Compared to Single-Dose Intramuscular Ceftriaxone Plus Single-Dose Oral Azithromycin in the Treatment of Male and Female Patients With Uncomplicated Urogenital Gonorrhea With or Without Concomitant Chlamydia

- Primary Endpoint
- To assess the eradication rate of Neisseria gonorrhoeae by culture following a single dose of oral solithromycin compared to single-dose intramuscular ceftriaxone plus oral azithromycin in the Microbiological Intent to Treat population.
Study Overview
Brief Summary
This study will compare a single dose of oral solithromycin to the standard of care (intramuscular ceftriaxone plus oral azithromycin) in the treatment of patients with urogenital gonorrhea. A completed open-label Phase 2 study with single doses of solithromycin resulted in 100% microbiological eradication in male and female patients with uncomplicated urogenital gonorrhea.
