简要总结
MTN-017 is a Phase 2, multi-site, randomized, six-sequence, two three-period, open label crossover study, examining the effects of oral Truvada and reduced glycerin 1% tenofovir gel. The study population will be sexually active, HIV-uninfected males who are 18 years of age or older, who report a history of receptive anal intercourse in the past 3 months. Each of the study product regimens offers different advantages to participants seeking an effective HIV prevention agent. How these relative advantages will compare in terms of safety, acceptability, systemic and local absorption, and adherence will be examined within this study.

结局指标
主要结局
Safety: Grade 2 or Higher Adverse Events
时间窗: 27 weeks (three 8-week product use periods with 1-week washout periods between them)
Compare the safety profiles of daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel. Analysis of the primary endpoint of grade 2 or higher AEs was performed on only the evaluable participants based on the principle of intent-to-treat (ITT) whereby participants who were randomized were included in the analysis regardless of whether or not they received product in a given period (i.e, were lost to follow-up, or terminated early and/or were on a product hold).
Acceptability: Participant Self-report of Liking the Product. H1-Overall How do You Feel About the Product You Used Recently?
时间窗: 27 weeks (three 8-week product use periods with 1-week washout periods between them)
To evaluate and compare acceptability of daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel. Consistent with the acceptability endpoint of liking the product, a variable was created by combining from Section H. Liking the Product of the MTN-017 Follow-up Behavioral Questionnaire question 1A and question 1BC. Categories 1 and 2 were combined and categories 3 and 4 were combined to create a dichotomous variable.
Acceptability: Participant Self-report of Likelihood of Product Use if Shown to be Effective. N1-If This Product Provides Some Protection How Likely Would You be to Take it?
时间窗: 27 weeks (three 8-week product use periods with 1-week washout periods between them)
To evaluate and compare acceptability of daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel. Consistent with the acceptability endpoint of likelihood to use product in the future, a variable was created by combining Section N. Likelihood to Use Product in the Future of the MTN-017 Follow-up Behavioral Questionnaire questions 1A, 1B, and 1C. Categories 1 and 2 were combined and categories 3 and 4 were combined to create a dichotomous variable.
Acceptability: Participant Self-report of Ease of Use. I1-Overall How Easy or Difficult Was it to Use the Product?
时间窗: 27 weeks (three 8-week product use periods with 1-week washout periods between them)
To evaluate and compare acceptability of daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel. Consistent with the acceptability endpoint of ease of use, a variable was created to compare regimens. This variable combines questions 1A and 1BC from Section I. Ease of Use of the MTN-017 Follow-up Behavioral Questionnaire. Categories 1 and 2 were combined and categories 3 and 4 were combined to create dichotomous variables.
