Purpose
This phase III, multi-centre, comparative, double-blind, randomized trial on 2 parallel groups is designed to evaluate a strategy for the prevention of HIV infection including "on demand" antiretroviral pre-exposure with Truvada versus placebo, associated with overall prevention (counselling, condoms, sexually transmitted diseases (STD) screening, HBV and HAV vaccinations and post-exposure treatment of HIV infection) in men who have sex with men (MSM), exposed to the risk of HIV infection. Indeed recent studies have reported a higher incidence of new HIV infection in MSM as compared to the general population, new approaches to the prevention of HIV infection are, therefore, necessary in order to consider the limits of current strategies.

Primary Outcome Measures:
- Contamination with HIV-1 or -2 [ Time Frame: From randomization to the end of the trial. The trial end date will be set by the scientific committee when the necessary number of primary endpoints has been reached without exceeding 4 years of follow-up. ] [ Designated as safety issue: No ]The primary endpoint criteria is contamination with HIV-1 or -2, defined by the first diagnostic proof of infection: positive HIV serum test (using combined latest-generation tests HIV-1 + 2) or a positive test for HIV-1-RNA PCR in the plasma.
Secondary Outcome Measures:
- Evolution of sexual behavior and potential at-risk behavior [ Time Frame: Every 2 months ] [ Designated as safety issue: No ]Self-questionnaires
- Incidence of clinical and biological adverse events [ Time Frame: From randomization to the end of the trial, without exceeding 4 years of follow-up. ] [ Designated as safety issue: Yes ]
- Treatment adherence [ Time Frame: Every 2 months ] [ Designated as safety issue: No ]Self-questionnaires, pill count. Drugs levels in plasma and hair (every 4 months).
- Incidence of hepatitis B [ Time Frame: From randomization to the end of the trial, without exceeding 4 years of follow-up ] [ Designated as safety issue: No ]
- Incidence of other sexually transmitted diseases [ Time Frame: From randomization to the end of the trial, without exceeding 4 years of follow-up ] [ Designated as safety issue: No ]
- Frequency of HIV resistance to antiretrovirals in HIV infected subjects [ Time Frame: At the visit in the event of HIV infection ] [ Designated as safety issue: No ]
- Emtricitabine and tenofovir concentrations in plasma, saliva and rectal samples. [ Time Frame: 0, 30 min, 1, 2, 4, 8 and 24 hours post-dose (2 tablets of Truvada) ] [ Designated as safety issue: No ]Ancillary study proposed between week-4 and the randomization - 12 volunteers. Blood and saliva samples at all time points and 2 sessions with rectal biopsies at two times for each volunteer (one before the drug is taken and one at one time after taking the 2 tablets)
- Costs evaluation [ Time Frame: From randomization to the end of the trial, without exceeding 4 years of follow-up. ] [ Designated as safety issue: No ]
Modelling to estimate an increase of years of life expectancy and of quality adjusted life year (QALY).

Detailed Description:
The trial has been taken place in two phases in order to ensure the general feasibility of the study:
- a first enrollment phase for at least 300 participants to ensure the possibility for recruitment in France and Canada and to validate the tools put into place as part of the trial to enroll and follow participants
- a second phase of 1600 additional participants. This extension phase started on July 2014.
The recruitement has been suspended following the recommendations of Data Safety and Monitoring Board (DSMB): the placebo arm has been stopped and Truvada is available for all the participants of the trial since November 2014.
