BACKGROUND Lipodystrophy commonly complicates antiretroviral therapy of HIV-1 infection. Thiazolidinediones such as rosiglitazone promote subcutaneous fat growth in type 2 diabetics and adults with congenital lipodystrophy, and can prevent HIV-1 protease inhibitor toxicity to adipocytes in vitro. We postulated that rosiglitazone would improve HIV(More)
Daily efavirenz 400 mg (EFV400) was virologically noninferior to 600 mg (EFV600) at 48 weeks in treatment-naïve patients. We evaluated EFV400 and EFV600 pharmacokinetics (NONMEM v. 7.2), assessing patient demographics and genetic polymorphisms (CYP2B6, CYP2A6, CYP3A4, NR1I3) as covariates and explored relationships with efficacy (plasma HIV-RNA (pVL) <200(More)
BACKGROUND Antiretroviral therapy has greatly reduced HIV mortality and morbidity. However, the best sequence of regimens and implications of initial regimen for long-term therapeutic success are not well defined. METHODS In INITIO, a large international randomised trial, we compared antiretroviral therapy with two nucleoside analogue reverse(More)
BACKGROUND ENCORE1 demonstrated non-inferiority of daily efavirenz 400 mg (EFV400) versus 600 mg (EFV600) to 96 weeks in treatment-naïve, HIV-infected adults but concerns regarding lower EFV400 concentrations remained. Therefore, relationships between EFV pharmacokinetics (PK) and key genetic polymorphisms with 96-week efficacy and safety were investigated.(More)
INTRODUCTION ENCORE1 compared the efficacy and safety of reduced versus standard dose efavirenz (EFV) with tenofovir/emtricitabine (TDF/FTC) as first-line HIV therapy. The primary analysis at 48 weeks showed 400 mg EFV was safe and virologically non-inferior to 600 mg. This analysis explores over 96 weeks the durability of efficacy and safety. MATERIALS(More)
