48 week bone marker changes with Dolutegravir (DTG) plus Abacavir/Lamivudine (ABC/3TC) vs. Tenofovir/Emtricitabine/Efavirenz (EFV/TDF/FTC): the SINGLE trial

چکیده
Background DTG is a once-daily integrase inhibitor that in combination with ABC/3TC, demonstrated superior efficacy with favorable tolerability over TDF/FTC/EFV (SINGLE study) at 48 weeks. EFV is associated with reduced Vitamin D levels through CYP450 enzyme induction; TDF has been associated with decreased bone mineral density (BMD). Antiretroviral treatment (ART) initiation is characterized by initial rapid decline in bone mineral density (BMD) that subsequently stabilizes. Bone turnover markers are increased during these BMD changes.

Dolutegravir plus abacavir-lamivudine for the treatment of HIV-1 infection.
BACKGROUND Dolutegravir (S/GSK1349572), a once-daily, unboosted integrase inhibitor, was recently approved in the United States for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in combination with other antiretroviral agents. Dolutegravir, in combination with abacavir-lamivudine, may provide a simplified regimen. METHODS We conducted a randomized, double-blind, phase...

BACKGROUND Integrase strand transfer inhibitors (INSTI) are the standard of care for naïve HIV-infected individuals due to their favourable efficacy and safety profile. The newest INSTIs, elvitegravir and dolutegravir, have not been evaluated in a head to head study; however, both have been compared to efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF) in phase III trials. Elvitegravir/cobicistat/...

OBJECTIVE Antiretroviral therapy initiation has been linked to bone mineral density and bone biomarker changes. We assessed long-term bone turnover biomarker effects over 144 weeks in patients initiating dolutegravir (DTG) + abacavir/lamivudine (ABC/3TC) versus efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF). METHODS Patients randomized in SINGLE received DTG (50 mg once d...
متن کاملCost-effectiveness of DTG+ABC/3TC versus EFV/TDF/FTC for first-line treatment of HIV-1 in the United States
INTRODUCTION Data from the SINGLE trial demonstrated that 88% of treatment-naive HIV-1 patients treated with dolutegravir and abacavir/lamivudine (DTG+ABC/3TC) achieved viral suppression at 48 weeks compared with 81% of patients treated with efavirenz/tenofovir disoproxil fumarate/emtricitabine (EFV/TDF/FTC). It is unclear how this difference in short-term efficacy impacts long-term cost-effect...

BACKGROUND Drug choice and metabolic changes with antiretroviral therapy contribute to cardiovascular risk in persons with HIV-1 infection. METHODS A randomized, 12 week, open-label, comparative study of the impact on lipids of continuation of abacavir/lamivudine (ABC/3TC) plus efavirenz (EFV) or replacement with the single tablet regimen of EFV/emtricitabine/tenofovir DF (EFV/FTC/TDF) in hyp...
