Study of HIV Patients With Undetectable Viral Load and Abnormal Lipids Switching to Atazanavir/Ritonavir - Full Text View

Purpose

Patients with HIV who are virologically suppressed on a lopinavir/ritonavir combination highly active antiretroviral therapy (HAART) regimen but with elevated non-HDL cholesterol are randomized to remain on lopinavir/ritonavir or change to atazanavir/ritonavir in combination with current nucleoside reverse transcriptase inhibitors (NRTIs).

Condition	Intervention	Phase
HIV Infections	Drug: atazanavir/ritonavir +2 NRTIs (immediate Switch Group) Drug: LPV/r +2 NRTIs (Delayed/optional Switch Group)	Phase 3


Study Type:	Interventional
Study Design:	Allocation: Randomized Intervention Model: Crossover Assignment Masking: None (Open Label) Primary Purpose: Treatment
Official Title:	A Phase IIIB, Open-label, Randomized, Multi-center Study Evaluating the Effect on Serum Lipids Following a Switch to ATV/r in HIV-1 Infected Subjects Who Have Achieved Virologic Suppression on a LPV/r Based Regimen.

Primary Outcome Measures:

To compare the Week 12 percent change from baseline in fasting non-HDL cholesterol between subjects who are switched to an ATV/RTV-containing regimen and those who continue on a LPV/RTV based regimen.

Secondary Outcome Measures:

Mean percent change in fasting non-HDL cholesterol at Weeks 24 and 48.
Mean change in cholesterol measures at Weeks 12, 24 and 48.
Mean percent changes from baseline in fasting glucose and insulin at Weeks 12, 24 and 48.
The proportion of subjects receiving lipid lowering therapy at Weeks 24 and 48.
The proportion of subjects with LDL cholesterol less than 130mg/dL at Weeks 12, 24 and 48.
The proportion of subjects with non-HDL cholesterol less than 160mg/dL at Weeks 12, 24 and 48.
The frequency and severity of all clinical and laboratory AEs and discontinue for AEs.
