Study information
Scientific title
Acronym
PENTA 5
Study hypothesis
Primary:
1. To compare the toxicity, tolerability and activity of three different 2-drug NRTI combinations in children taking either NFV or NFV placebo in Part A, and in those taking NFV in Part B. Activity will be assessed by effect on viral load measured by plasma HIV-1 RNA
2. To assess the tolerability and toxicity of NFV and NFV placebo in children in Part A
Secondary:
1. To compare the activity of NFV and NFV placebo in children taking one of the three 2-drug combinations in Part A
2. To describe the effect on viral resistance, CD4 cell count and clinical progression separately for the three NRTI groups and the NFV and NFV placebo groups
3. To compare the plasma viral load as measured by HIV-1 RNA in the 1592-containing arms with that in the non-1592 arms in children taking NFV or NFV placebo

Drug names
Primary outcome measure
1. To compare the combination of two NRTIs plus a protease inhibitor (PI) versus two NRTIs plus a non-nucleoside reverse transcriptase inhibitor (NNRTI) as initial therapy, followed by second-line therapy if virologic failure occurs, in terms of their effects on a long-term virologic endpoint
2. To compare two different viral load criteria for switching from first-line to second-line therapy
Secondary outcome measures
1. To evaluate and compare the safety and tolerability of each drug combination (including first- and second-line therapies)
2. To compare the long-term clinical and immunologic outcomes (by the initial randomization)
3. To compare the proportions of children who have undergone one regimen switch or reached study end-point (by the initial randomization)
4. To compare time from randomization to virologic failure (RNA >400 copies/ml at or after week 24) of the first-line therapy analyzed by initial randomization to either protease inhibitor (PI) or NNRTI containing regimens
5. To compare time from randomization to virologic failure of the second line therapy (RNA >30,000 copies/ml) analyzed by the initial randomization
6. To compare the proportion of children with plasma HIV-1 RNA <400 copies/ml at 4 years (by the initial randomization)
7. To describe resistance patterns at 4 years (by the initial randomization)
