Exclusion Criteria

• Male participants with a current diagnosis of epididymitis and/or orchitis at the time of the Baseline Visit.
• Participant who is suspected or confirmed to have a Chlamydia trachomatis infection and per the investigator's judgement standard-of-care treatment for this infection cannot be safely postponed until the TOC Visit.
• Participant has a body mass index >=40 kilogram per square meter (kg/m^2) or has a body mass index >=35.0 kg/m^2 and is experiencing obesity-related health conditions such as high blood pressure or diabetes.
• Participant has a history of sensitivity to the study treatments, or components thereof, or a history of a drug (including erythromycin and any macrolide or ketolide drug) or other allergy that, in the opinion of the investigator or medical monitor, contraindicates his or her participation.
• 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 =12 to 450 millisecond (msec) or a QTc >480 msec for participants with bundle-branch block.
• Participant has a documented or recent history of uncorrected hypokalemia within the past 3 months.
• Participant has a known history of cholestatic jaundice or hepatic dysfunction associated with prior use of azithromycin.
• Participant has a known alanine aminotransferase (ALT) value >2 times upper limit of normal (ULN).
• Participant 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%).
• Participant 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
