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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Pharmacodynamics | To characterize pharmacodynamic responses following oral and rectal exposure to antiretroviral drugs | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Mucosal Immunity | To characterize changes in mucosal immunity between baseline and the end of the daily FTC/TDF and TFV RG 1% gel product use | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Correlation Between PK and Adherence | To assess correlation of PK with adherence measures | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Factors Associated With Adherence | To identify factors associated with product adherence and whether they differ by product used (FTC/TDF or TFV RG 1% gel) or regimen (daily use or RAI-associated use) | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Sexual Activity and Condom Use | To examine whether sexual activity or condom use varies by product used | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Product Sharing | To determine the level of sharing of study products with non-participants and to assess with whom products are shared | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Other | Problem Practices | To determine the prevalence of behavioral practices associated with anal intercourse that may affect microbicide use | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Primary | Safety: Grade 2 or Higher Adverse Events | 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). | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Primary | Acceptability: Participant Self-report of Liking the Product. H1-Overall How do You Feel About the Product You Used Recently? | 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. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Primary | Acceptability: Participant Self-report of Ease of Use. I1-Overall How Easy or Difficult Was it to Use the Product? | 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. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Primary | 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? | 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. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: Tenofovir (TFV) Concentrations (log10 ng/mL) in Blood Plasma | Compare tenofovir concentrations in blood plasma among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: End Period Tenofovir (TFV) Concentrations (log10 ng/mg) in Rectal Tissue | Compare end period tenofovir concentrations in rectal tissue among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: Tenofovir (TFV) Concentrations (log10 ng/mg) in Rectal Sponge | Compare tenofovir concentrations in rectal sponge specimens among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: Emtricitabine (FTC) Concentrations (log10 ng/mL) in Blood Plasma | Compare emtricitabine concentrations in blood plasma among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: End Period Emtricitabine (FTC) Concentrations (log10 ng/mg) in Rectal Tissue | Compare end period emtricitabine concentrations in rectal tissue among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: Emtricitabine (FTC) Concentrations (log10 ng/mg) in Rectal Sponge | Compare emtricitabine concentrations in rectal sponge among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Pharmacokinetics: End Period Tenofovir-Diphosphate (TFV-DP) Concentrations (log10 ng/mg) in Rectal Tissue | Compare end period tenofovir-diphosphate (TFV-DP) concentrations in rectal tissue among daily FTC/TDF tablet, daily TFV RG 1% gel, and RAI-associated TFV RG 1% gel groups. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) | |
Secondary | Adherence: Percentage of Prescribed Doses Taken Orally or Administered Rectally in an 8-week Period | Compare percentage of prescribed doses taken orally or administered rectally in an 8-week period based on the Final Converged Rates. Final Converged Rates were measured first via self-report through Short Message Service (SMS). The clinic staff also reported the most likely number of doses taken. Finally, the MTN Behavioral Research Working Group (BRWG) provided the final estimate of the number of doses taken for each participant for each period based on self-report, staff estimates and PK testing results. Note that these final judgement data are missing if PK results are missing. | 27 weeks (three 8-week product use periods with 1-week washout periods between them) |
