A Study Evaluating Efficacy and Safety of Gepotidacin Compared With Ceftriaxone Plus Azithromycin in the Treatment of Uncomplicated Urogenital Gonorrhea

Completed · Phase 3

Conditions studied: Gonorrhea

In brief

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 participants. In this study, participants will be randomly assigned to receive either oral gepotidacin or IM ceftriaxone plus oral azithromycin.

Participant is immunocompromised or has altered immune defenses that may predispose the participant to a higher risk of treatment failure and/or complications.
Participants with a known cluster of differentiation 4 (CD4) count of <200 cells per cubic millimeter (cells/mm\^3).
Participant has any of the following: poorly controlled asthma or chronic obstructive pulmonary disease, 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 or participant has any surgical or medical condition that may interfere with drug absorption, distribution, metabolism, or excretion of the study treatment.
Participant 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).
Participant in the judgment of the investigator, would not be able or willing to comply with the protocol or complete study follow-up.
Participant has a serious underlying disease that could be imminently life threatening, or the participant is unlikely to survive for the duration of the study period.
Participant has congenital long QT syndrome or known prolongation of corrected QT interval (QTc).
Participant has uncompensated heart failure.
Participant has severe left ventricular hypertrophy.
Participant has a family history of QT prolongation or sudden death.
Participant has a recent history of vasovagal syncope or episodes of symptomatic bradycardia or bradyarrhythmia within the last 12 months.
The participant is taking QT-prolonging drugs or drugs known to increase the risk of torsades de pointes (TdP) per the 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 participant is taking a strong cytochrome P450 enzyme 3A4 (CYP3A4) inhibitor or a strong P-glycoprotein (P-gp) inhibitor.
For any participant >=12 to <18 years, the participant has an abnormal electrocardiogram (ECG) reading.
