MeasureTime frame
Main Objective: 1) To evaluate the change in total cholesterol, triglycerides, non-HDL-C, and LDL-C associated with the use of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as measured by the mean percent change from baseline in total cholesterol, triglycerides, non-HDL-C, and LDL-C at Week 12. 2) To evaluate the antiretroviral activity of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as measured by proportion of patients with viral load <50 copies/mL at Week 24. 3) To evaluate the safety and tolerability of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as assessed by review of the accumulated safety data at Week 24.;Secondary Objective: 1) To evaluate the change in total cholesterol, triglycerides, non-HDL-C, and LDL-C associated with the use of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as measured by the mean percent change from baseline in total cholesterol, triglycerides, non-HDL-C, and LDL-C at Week 24 and 48. 2) To evaluate the antiretroviral activity of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as measured by the proportion of patients with viral load <50 copies/mL at Week 48 and the change from baseline in CD4 cell counts at Week 24 and Week 48. 3) To evaluate the safety and tolerability of MK-0518 400 mg b.i.d. compared with KALETRA 400/100 mg b.i.d., each in combination with background antiretroviral therapy, as assessed by review of the accumulated safety data at Week 48. ;Primary end point(s): Efficacy - proportion of patients with plasma HIV RNA < 50 copies/mL at Week 24. Safety - mean percent changes from baseline in total cholesterol, triglycerides, non-HDL-C
