Treatment: Drugs - Gepotidacin
Treatment: Drugs - Ceftriaxone
Treatment: Drugs - Azithromycin

Experimental: Participants receiving Gepotidacin - Participants will receive Gepotidacin orally at the study site during the Baseline (Day 1) visit followed by self-administration of a second oral dose as an outpatient 10 to 12 hours after the first dose.

Treatment: Drugs: Ceftriaxone
Ceftriaxone is available as sterile powder for reconstitution. It will be administered as one 500-mg IM dose at the study site.

Summary
Brief summary
This is a phase III, randomized, multicenter, open-label study which will be performed to
