Dual Therapy in HIV Patients in 4 Days a Week Versus 7 Days a Week

Phase 3
Conditions
HIV Infections
Interventions
Drug: ARV bitherapie
Registration Number
NCT04867083
Lead Sponsor
ANRS, Emerging Infectious Diseases
Brief Summary

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.

Detailed Description

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%.
