Capacity of the Dual Combination Raltegravir/Etravirine to Maintain Virological Success in HIV-1 Infected Patients of at Least 45 Years of Age- ANRS 163 ETRAL

Phase 2
Completed
Conditions
HIV-1 Infection
Interventions
Registration Number
NCT02212379
Lead Sponsor
ANRS, Emerging Infectious Diseases
Brief Summary

This multicenter, international, non randomized (single arm), open, phase II trial aims to evaluate the capacity of the dual combination raltegravir/etravirine to maintain virological success in virologically suppressed HIV-1 infected patients, of at least 45 years of age, switching from a boosted PI-containing regimen. Patients will be followed for 96 weeks. The primary endpoint was the proportion of participants with virological success at 48 weeks. Virological success is defined as the absence of 2 consecutive plasma viral load \>50 copies/mL within 2 to 4 weeks apart. The study was designed to show an efficacy \>90%, assuming a success rate \>95%, with a power of 80% and a 5%type-1 error. A total of 160 individuals was required to achieve the objective. The principal secondary endpoint is the proportion of patients in therapeutic success up to week 48 and 96.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Successful Virological Suppression at Weeks 48 and 96at week48 and at week 96

Virological success is defined as the absence of 2 consecutive plasma viral loads (VL) \> 50 copies/mL within 2 to 4 weeks of a dual raltegravir/etravirine regimen.

The proportion of patients who maintained viral suppression under raltegravir plus etravirine was 99.4% (95% confidence interval (95% CI:95.6 -99.9) at week 48 and 98.7% (95% CI: 95.0 -99.7) at week 96
