Open-label, multicenter, prospective, randomized trial in 2 parallel groups, evaluating at W48 the non-inferiority of antiretroviral dual therapy taken 4 consecutive days a week versus dual therapy taken 7 days a week, in HIV infected patients with controlled viral load for at least 12 months and stable antiretroviral dual therapy since 4 months. The non-inferiority margin (delta) is 5%. The randomization will be stratified according to the family of the dual therapy at the moment of the inclusion and according to the participation of the substudy or not.~The sample size calculation assumes that the true difference in efficacy between the two arms is zero and that the overall response rate is 97% at week 48. A total of 440 patients (220 per arm) is required to provide 80% power to demonstrate non-inferior efficacy for the 4/7 strategy, compared to the daily dual therapy (7/7), with a two-sided significance level of 5% and a non-inferiority margin (delta) of -5%.
The trial is an open-label, multicenter, prospective, randomized trial in 2 parallel groups, evaluating at W48 the non inferiority of antiretroviral dual therapy taken 4 consecutive days per week versus antiretroviral dual therapy 7/7 days per week in HIV-1 infected patients with controlled viral load under antiretroviral dual therapy.
