Design outcomes

Primary

MeasureTime frame
Main Objective: The aim of this clinical trial is to compare the efficacy and safety of RTV-boosted atazanavir with nevirapine in two different dosing schedules, each on a background of emtricitabine and tenofovir DF.;Secondary Objective: •Change in fasting plasma levels of total cholesterol and in its fractions (HDLC and LDLC), the TC : HDLC ratio, in apolipoprotein A1 and B, hsCRP and total triglyceride levels from baseline to after 48, 96 and 144 weeks of treatment •Change in the estimated cardiovascular risk using the Framingham algorithm of the patients in each treatment group from baseline to after 48, 96 and 144 weeks of treatment •Change in quality of life from baseline to after 24, 48, 96 and 144 weeks of treatment •Cost-effectiveness of each treatment regimen in the time periods from baseline to after 24, 48, 96 and 144 weeks of treatment ;Primary end point(s): The primary endpoint is the treatment response (TR) at Week 48. TR is defined as HIV viral load of < 50 copies/ml measured at two consecutive visits prior to Week 48 and without subsequent rebound or change of ARV therapy prior to Week 48. If the VL is = 50 copies/ml at Week 48 and this is the first sequential VL value = 50 copies/ml following treatment response, then another measurement at least 2 weeks later is necessary to determine whether rebound has occurred. A rebound is defined by two consecutive measurements of VL = 50 copies/ml, at least two weeks apart, after two consecutive measurements of VL < 50 copies/ml. A change of ARV therapy is either defined as: •A permanent discontinuation of study drug or its control •A change in the dose of ATZ or RTV A change from NVP once daily to twice daily administration and vice versa is not considered failure for the primary analysis. Therefore, a patient remains a treatment responder in this case if all other criteria are fulfilled.
