This is a phase III, randomized, multicenter, open-label study which will be performed to evaluate efficacy and safety of oral Gepotidacin compared to intramuscular (IM) ceftriaxone plus oral azithromycin for the treatment of uncomplicated urogenital infection caused by Neisseria gonorrhoeae (N. gonorrhoeae) in adolescent and adult subjects. In this study, subjects will be randomly assigned to receive either oral gepotidacin or IM ceftriaxone plus oral azithromycin. Approximately 600 subjects will be randomized to receive study treatment. The duration of the study will be approximately 21 days.

Female subject is eligible to participate if she is not pregnant, not breastfeeding, and at least 1 of the following conditions applies: Not a woman of childbearing potential (WOCBP) or WOCBP who agrees to follow the contraceptive guidance (male partners of WOCBP must use a male condom during intercourse) from the Baseline Visit through completion of the TOC Visit
Subjects who are capable of giving signed informed consent or assent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) or assent form and in study protocol

Exclusion Criteria

Male subjects with a current diagnosis of epididymitis and/or orchitis at the time of the Baseline Visit

Subject is immunocompromised or has altered immune defenses that may predispose the subject to a higher risk of treatment failure and/or complications. For example, subjects with diabetes, renal transplant recipients, subjects with clinically significant persistent granulocytopenia (absolute neutrophil count <1000 per microliter [μL]) and subjects receiving immunosuppressive therapy, including corticosteroid therapy (>40 mg per day prednisolone or equivalent for >1 week, >=20 mg per day prednisolone or equivalent for >2 weeks, or prednisolone or equivalent >=10 mg per day for >6 weeks). Subjects with a known cluster of differentiation 4 (CD4) count of <200 cells per cubic millimeter (cells/mm^3) should not be enrolled
Subject has a medical condition that requires medication that may be impacted by inhibition of acetylcholinesterase, such as, poorly controlled asthma or chronic obstructive pulmonary disease at the Baseline Visit and, in the opinion of the investigator, not stable on current therapy, acute severe pain, uncontrolled with conventional medical management, active peptic ulcer disease, Parkinson disease, Myasthenia gravis, a history of seizure disorder requiring medications for control (this does not include a history of childhood febrile seizures) or subject has any surgical or medical condition (active or chronic) that may interfere with drug absorption, distribution, metabolism, or excretion of the study treatment (For example., ileostomy or malabsorption syndrome)
Subject has known anuria, oliguria, or severe impairment of renal function (creatinine clearance <30 milliliter per minute [mL/min] or clinically significant elevated serum creatinine as determined by the investigator)
Subject in the judgment of the investigator, would not be able or willing to comply with the protocol or complete study follow-up
Subject has a serious underlying disease that could be imminently life threatening, or the subject is unlikely to survive for the duration of the study period
Subject has congenital long QT syndrome or known prolongation of corrected QT interval (QTc)
Subject has uncompensated heart failure
Subject has severe left ventricular hypertrophy
Subject has a family history of QT prolongation or sudden death
Subject has a recent history of vasovagal syncope or episodes of symptomatic bradycardia or bradyarrhythmia within the last 12 months
The subject is taking QT-prolonging drugs or drugs known to increase the risk of torsades de pointes (TdP) per the [www.crediblemeds.org](http://www.crediblemeds.org/) "Known Risk of TdP" category at the time of his or her Baseline Visit, which cannot be safely discontinued from the Baseline Visit to the TOC Visit; or the subject is taking a strong cytochrome P450 enzyme 3A4 (CYP3A4) inhibitor or a strong P-glycoprotein (P-gp) inhibitor
For any subject >=12 to <18 years, the subject has an abnormal electrocardiogram (ECG) reading
The subject has a QTc >450 millisecond (msec) or a QTc >480 msec for subjects with bundle-branch block
Subject has a documented or recent history of uncorrected hypokalemia within the past 3 months
Subject has a known history of cholestatic jaundice or hepatic dysfunction associated with prior use of azithromycin
Subject has a known alanine aminotransferase (ALT) value >2 times upper limit of normal (ULN)
Subject has a known bilirubin value >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%)
Subject has a current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones), including symptomatic viral hepatitis or moderate-to-severe liver insufficiency (Child Pugh class B or C)
Subject has been previously enrolled in this study or has previously been treated with Gepotidacin
Subject has participated in a clinical trial and has received an investigational product within 30 days or 5 half-lives, whichever is longer
