This protocol describes a prospective, randomized, open-label, multicenter study to evaluate the safety and efficacy of switching from fixed dose ABC/3TC to fixed dose FTC/TDF in virologically suppressed, HIV-1 infected subjects maintained on a PI/r-containing ARV regimen.~Subjects were stratified based on the PI/r (ie, lopinavir/ritonavir [LPV/r] versus other boosted PIs) in their regimen, and the presence versus absence of comorbidities at screening (diabetes mellitus or cardiovascular disease such as hypertension, coronary artery disease, hyperlipidemia, history of myocardial infarction, cardiomyopathy, valvular heart disease, congenital heart disease, stroke, peripheral vascular disease, or arrhythmias). Subjects were randomized 1:1 to switch to FTC/TDF+PI/r or to continue on their existing regimen.~Subjects received study treatment for 48 weeks.
This protocol describes a prospective, randomized, open-label, multicenter study to evaluate the safety and efficacy of switching from fixed dose abacavir (ABC)/lamivudine (3TC) to fixed dose emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) in virologically suppressed, human immunodeficiency virus type 1 (HIV-1) infected subjects maintained on a ritonavir-boosted protease inhibitor (PI/r)-containing antiretroviral (ARV) regimen. Duration of treatment is 48 weeks.
