About this study

Official title: An Exploratory Study of Potential Sources of Efficacy Dilution in the VOICE Trial

This study is primarily exploratory and is designed to both identify factors that may have affected participant adherence to study product in VOICE, and describe how sexual behaviors, such as anal sex, may have had an effect on product efficacy. As such there is no specific hypothesis that is being tested.

Read the detailed description

MTN-003D will use qualitative in-depth interviews and/or focus group discussions with VOICE participants to explore study product adherence and/or anal sex behaviors in greater depth than was measured quantitatively during trial participation. The study approach is designed to encourage honesty and to minimize socially desirable responses, which may have affected participants' ability/willingness to accurately report during the trial. An in-depth and candid understanding of the various behavioral factors that contribute to the dilution of efficacy may assist in the interpretation of VOICE trial results and inform future studies.

In light of VOICE's divergent results, MTN-003D will explore the potential factors that may have contributed to efficacy dilution in the trial. MTN-003D, was initially designed after the early closure of the oral and vaginal tenofovir arms, and sought to explore those factors contributing to the dilution of efficacy using qualitative methods (Stage 1). Given the subsequent release of VOICE results in February of 2013 and the availability of drug PK data, Stage 2 of MTN-003D has been designed to explore factors influencing adherence in greater depth, including HIV risk perception and motivation to join the trial.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Contextual issues affecting product use

    To explore larger contextual issues and specific aspects of the VOICE trial that positively and negatively affected participants' actual and reported product use.

    Measured: End of Study

Secondary outcomes (1)
  1. Explore risk perceptions and motivation to join VOICE study

    To explore participants' risk perceptions and motivations to participate in VOICE and the association of these factors with product use or non-use in a prevention trial setting.

    Measured: End of Study
