简要总结
Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection.
The goals of this study are to learn:
- If taking MK-8527 once a month works to prevent HIV-1 infection as well as or better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day
- About the safety of MK-8527 and if people tolerate it

结局指标
主要结局
Number of Participants With Adjudicated Human Immunodeficiency Virus Type 1 (HIV-1) Infection
时间窗: Up to approximately 2 years
The number of participants with adjudicated HIV-1 infection will be determined.
Number of Participants Who Experience At Least One Adverse Event (AE)
时间窗: Up to approximately 2 years
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that experienced AEs will be reported.
Number of Participants Who Discontinue Study Intervention Due to an AE
时间窗: Up to approximately 2 years
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that discontinued study intervention due to an AE will be reported.
