Primary Outcome Measures:
  • The number of subjects who died [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: Yes ]
  • The frequency of Serious Adverse Events (SAEs) [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: Yes ]
  • The frequency of Adverse Events (AEs) leading to discontinuation [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Proportions of subjects with HIV ribonucleic acid (RNA) < 50 c/mL and < 400 c/mL at week 48 [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
  • Maximum concentration (Cmax) of ATV powder boosted with RTV in pediatric subjects weighing 5 - <10 kg, ≥25 - <35 kg and/or aged ≥6 - <11 years [ Time Frame: 2 weeks after reaching this weight/age band ] [ Designated as safety issue: No ]
  • Minimum concentration (Cmin) of ATV powder boosted with RTV in pediatric subjects weighing 5 - <10 kg, ≥25 - <35 kg and/or aged ≥6 - <11 years [ Time Frame: 2 weeks after reaching this weight/age band ] [ Designated as safety issue: No ]
  • Area under the curve (AUC) of ATV powder boosted with RTV in pediatric subjects weighing 5 - <10 kg, ≥25 - <35 kg and/or aged ≥6 - <11 years [ Time Frame: 2 weeks after reaching this weight/age band ] [ Designated as safety issue: No ]
