Brief summary
The main objective is to determine the feasibility of maintaining virologic suppression on standard plasma viral load by dose reduction of ATRIPLA ®.
Detailed description
The main objective of this study is to determine the feasibility of maintaining virologic suppression on standard plasma viral load (limit of detection 37 copies / mL) of a dose reduction strategy of ATRIPLA ® once a day to three tablets per week in patients infected with HIV-1 with sustained suppression of plasma viral load standard for more than two years.

Participant flow
Recruitment details
Participants were recruited between 3 June 2013 and 30 May 2014 at Hospital Clínic of Barcelona.
Pre-assignment details
68 patients were assessed for eligibility, 61 underwent randomization and received at least one dose of study drugs. Seven patients were excluded because of refusal to participate (lack of time, n¼4; lack of interest, n¼1; fear of viral failure, n¼1) or evidence of illicit drug consumption (n¼1).
