Primary purpose of this study is to compare the efficacy and safety of two different nevirapine (Viramune) dosing regimens (once daily and twice daily application) and of atazanavir/ritonavir (Reyataz/Norvir), all on an emtricitabine/tenofovir DF (Truvada) background. Patients will receive either nevirapine (NVP) 200 mg twice daily, or NVP 400 mg once daily, or ritonavir-boosted atazanavir (ATZ/r), all in combination with emtricitabine (FTC) and tenofovir DF (TDF).
All patients receiving NVP will start at 200 mg QD for 2 weeks, because it has been demonstrated that this lead-in dosing regimen reduces the frequency of NVP-induced rash. At Visit 3 (Week 2), patients increase the NVP dose to either 200 mg BID or to 400 mg QD. Patients receiving ATZ/r will be treated with ATZ 300 mg once daily, boosted by 100 mg ritonavir (RTV) once daily. Background antiretroviral therapy for all patients consists of one tablet of Truvada. Treatment duration is 48 weeks (primary endpoint) with an extension to 144 weeks. Patients may also participate in the metabolic sub-study, comparing NVP and ATZ/r for signs and symptoms of lipodystrophy and serum lipid/glycaemic abnormalities.

ATV/Ritonavir Nevirapine Interaction (USPAC)
Open-Label, multiple-dose, drug interaction study to assess the effect of nevirapine on the pharmacokinetics of atazanavir in HIV-infected individuals.
The aim of this clinical trial is to compare the efficacy and safety of RTV-boosted atazanavir with nevirapine, each on a background of emtricitabine and tenofovir DF.
The purpose of this study is to evaluate the influence of nevirapine in exposure to atazanavir boosted with ritonavir, in steady state equilibrium, in HIV-infected adult patients.
The primary objective of this study is to evaluate the efficacy of 400 mg QD nevirapine extended release (NVP XR) formulation versus 200 mg BID nevirapine immediate release (NVP IR) in ARV...

Nevirapine (NVP) is recommended by WHO as the antiretroviral treatment to prevent HIV passing from mother to child. However, the once-daily oral administration results in poor patient compliance, and ...
Atazanavir intracellular concentrations remain stable during pregnancy in HIV-infected patients.
Atazanavir (300 mg) boosted by ritonavir (100 mg) is the preferred third drug in pregnancy. However, there is still discordance on atazanavir dose increase during the third trimester.
To compare the effect of pre-conception initiation of zidovudine, lamivudine, nevirapine (ZDV/3TC/NVP) versus tenofovir, emtricitabine, efavirenz (TDF/FTC/EFV) on adverse birth outcomes.
