Brief Summary:
This trial is a multi-center, open label, randomized controlled, non-inferiority phase III trial evaluating the safety and efficacy of a 3 g oral dose of zoliflodacin compared to a combination of a single intra-muscular 500 mg dose of ceftriaxone and a single 1 g oral dose of azithromycin for the treatment of uncomplicated gonorrhoea.

Primary Outcome Measures :
- Efficacy of a single dose of zoliflodacin will be assessed compared to a combination of a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Microbiological cure as determined by culture at urethral or cervical sites at test of cure visit.
Secondary Outcome Measures :
- Safety of a single dose of zoliflodacin will be assessed compared to a combination a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 and Day 30 ]Adverse events will be assessed.
- Microbiological cure rate of pharyngeal gonorrhoea will be determined after administration of a single dose of zoliflodacin compared to a combination of a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Proportion of participants with microbiological cure as determined by culture at pharyngeal sites at test of cure visit.
- Microbiological cure rate of rectal gonorrhoea will be determined after administration of a single dose of zoliflodacin compared to a combination of a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Proportion of participants with microbiological cure as determined by culture at rectal sites at test of cure visit.
- The clinical cure rate of symptomatic gonorrhoea in male participants will be determined after administration of a single dose of zoliflodacin compared to a combination of single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Proportion of male participants with clinical cure at test of cure visit.
- Microbiological cure rate of urogenital gonorrhoea will be determined among women and men respectively, after administration of a single dose of zoliflodacin compared to a combination of a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Proportion of female and male participants respectively with microbiological cure as determined by culture at cervical or urethral site at test of cure visit.
- Microbiological cure rate of Neisseria gonorrhoeae (NG) at urogenital sites will be determined. [ Time Frame: Day 6 ]Proportion of participants with microbiological cure as determined by culture at urethral or cervical sites at the test of cure visit and for whom the baseline antimicrobial susceptibility profile indicated pre-existing resistance to antibiotics commonly used for Neisseria gonorrhoeae (NG) treatment.
- Antimicrobial susceptibility profile will be determined of gonococcal strains isolated from participants with uncomplicated gonorrhoea at baseline and the test of cure visit. [ Time Frame: Day 6 ]Antimicrobial susceptibility profile of gonococcal strains isolated at baseline and at test of cure visit.
- The eradication rate of NG nucleic acid will be determined from urogenital rectal, pharyngeal specimens after administration of a single dose of zoliflodacin compared to a combination of a single dose of ceftriaxone and azithromycin. [ Time Frame: Day 6 ]Proportion of participants with a negative NG NAAT from urethral or cervical, oropharyngeal and rectal sites at test of cure visit.
- The plasma concentration will be evaluated (included Area Under the Curve (AUC) over 36 hours) after a single dose of zoliflodacin. [ Time Frame: Day 2 ]Five PK timepoints post-treatment will be assessed.

- Severe medical or psychiatric condition which, in the opinion of the investigator, may increase the risk associated with trial participation or may interfere with the interpretation of trial results or affect the individual's ability to provide informed consent
- Individuals whom, in the judgement of the investigator, are unlikely or unable to comply with this trial protocol
- Previous randomisation in this clinical trial.
- Use of moderate or strong CYP3A4 inhibitors within 30 days or five half-lives of the drug, whichever is greater, prior to screening
