Efficacy and Safety Study of Oral Solithromycin Compared to Intramuscular Ceftriaxone Plus Oral Azithromycin in the Treatment of Patients With Gonorrhea

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.

Primary outcomes

  1. 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.

    Time frame: 7 days after treatment

Secondary outcomes

  1. To assess the safety and tolerability of a single oral dose of solithromycin compared to single-dose IM ceftriaxone plus single-dose oral azithromycin in patients with gonorrhea

    Time frame: 7 days

    Adverse event frequency and severity will be compared between patients who received solithromycin and those who received ceftriaxone plus azithromycin

  2. To compare bacterial eradication rates of N. gonorrhoeae from rectal or pharyngeal cultures following a single dose of oral solithromycin compared to single-dose IM ceftriaxone plus oral azithromycin.

    Time frame: 7 days

  3. To assess clearance or persistence of N. gonorrhoeae and Chlamydia trachomatis nucleic acid from male and female genital, pharyngeal and rectal specimens.

    Time frame: 21 days after treatment
