Clinical Trial Summary

This is an exploratory mixed-methods research study that compares an efficacious behavioral HIV-prevention intervention (3MV) alone to the behavioral HIV-prevention intervention combined with a biomedical intervention (PrEP). After completing the 3MV behavioral intervention, participants will be randomly assigned to one of three study arms: 1) daily FTC/TDF as PrEP, 2) placebo pill control, or 3) "no pill" control. Behavioral and biomedical data will be collected at baseline and every 4 weeks thereafter for 24 weeks. Youth who decline to participate will be asked to complete a brief survey about their opinions on PrEP. Qualitative interviews will be completed with six study participants and the study coordinators at the end of the trial to explore further the issues of trial acceptability and feasibility. Finally, focus groups will be conducted to explore feasibility and acceptability issues with YMSM who meet all eligibility requirements of the study except for not being age 18 or older, but are at least 16 years of age.

Primary	Number of Missed Doses Based on Self-Report Calendar Data-Week 4	Missed doses were calculated as the number of days between the date that subject came in for their current visit and the last date the subject was dispensed medication minus the total number of days the subject records having taken their medication in the last 31 days based on self-report calendar data. Since each subject is given a 30 day supply of medication at each visit, any days after 30 days are assumed to be missed medication days and are included in the total. Participants were taking only one dose per day and thus, the number of missed doses is the same as the number of missed medication days.	4 weeks
Primary	Number of Missed Doses Based on Self-Report Calendar Data-Week 8	Missed doses were calculated as the number of days between the date that subject came in for their current visit and the last date the subject was dispensed medication minus the total number of days the subject records having taken their medication in the last 31 days based on self-report calendar data. Since each subject is given a 30 day supply of medication at each visit, any days after 30 days are assumed to be missed medication days and are included in the total. Participants were taking only one dose per day and thus, the number of missed doses is the same as the number of missed medication days.	Week 8
Primary	Number of Missed Doses Based on Self-Report Calendar Data-Week 12	Missed doses were calculated as the number of days between the date that subject came in for their current visit and the last date the subject was dispensed medication minus the total number of days the subject records having taken their medication in the last 31 days based on self-report calendar data. Since each subject is given a 30 day supply of medication at each visit, any days after 30 days are assumed to be missed medication days and are included in the total. Participants were taking only one dose per day and thus, the number of missed doses is the same as the number of missed medication days.	Week 12
