PrimaryThe Number of Participants With a Serological Response by Month 6.Day 1 to Day 180
Serological response to therapy by Month 6 was defined as follows, where available rapid plasma reagin (RPR) results from all visits prior to the end of the Month 6 visit window (i.e., scheduled visits up to and including the Month 6 visit, early termination visit, or any unscheduled visit that occurred prior to the end of month 6 visit window) were evaluated: * 4-fold or greater decline in RPR titer at any visit prior to the end of the Month 6 visit window compared to baseline, OR * RPR-negative at any visit prior to the end of the Month 6 visit window (i.e., seroreversion).

SecondaryThe Number of Participants Who Receive All Assigned Doses Within the Assigned Visit WindowsThrough Month 12
Compliance with study product will be defined as the participant received all assigned doses within the assigned visit windows. A participant is not adherent to study product if they miss at least one dose or receive at least one dose out of the visit window.
SecondaryThe Number of Participants Who Report Jarisch-Herxheimer Reaction ManifestationsDay 1 through Day 2
Approximately 24 hours after Visit 1, participants were contacted and evaluated for symptoms of a JHR, which included fever, chills, myalgia, weakness, flushing, worsening of skin rash, tachycardia, heart palpitations, arthralgia, nausea, headache, and dizziness, including time of onset and time of resolution of each symptom reported.
SecondaryNumber of Participants With Serological Response by Month 6 Among Participants With or Without HIV InfectionDay 1 to Day 180
Serological response to therapy by Month 6 was defined as follows, where available rapid plasma reagin (RPR) results from all visits prior to the end of the Month 6 visit window (i.e., scheduled visits up to and including the Month 6 visit, early termination visit, or any unscheduled visit that occurred prior to the end of month 6 visit window) were evaluated: * 4-fold or greater decline in RPR titer at any visit prior to the end of the Month 6 visit window compared to baseline, OR * RPR-negative at any visit prior to the end of the Month 6 visit window (i.e., seroreversion). Serological response to therapy by Month 6 was examined among participants with and without HIV infection,

Through month 12
Serological response to therapy by Month 12 was defined as follows, where available rapid plasma reagin (RPR) results from all visits prior to the end of the Month 12 visit window (i.e., scheduled visits up to and including the Month 12 visit, early termination visit, or any unscheduled visit that occurred prior to the end of month 12 visit window) were evaluated: * 4-fold or greater decline in RPR titer at any visit prior to the end of the Month 12 visit window compared to baseline, OR * RPR-negative at any visit prior to the end of the Month 12 visit window (i.e., seroreversion).
