Brief summary:
The purpose of this study is to collect safety clinical data in HIV-infected pediatric patients aged 6 and older to younger than18 years and weighing 15 kg or more, who are receiving atazanavir capsule boosted with ritonavir and an optimized nucleoside reverse transcriptase inhibitor backbone therapy as part of their antiretroviral regimen.

Detailed description:

Arms:
arm 1: Participants with baseline weight of 15 to \<20 kg received 150 mg of atazanavir plus 100 mg of ritonavir once daily with an optimized background therapy of 2 nucleoside reverse transcriptase inhibitors (NRTIs) for 24 weeks. In countries without locally approved pediatric indication for atazanavir, patients may continue to receive study treatment, with regular 12-week visits, until the age of 18 years. arm 2: Participants with baseline weight of 20 to \<40 kg received 200 mg of atazanavir plus 100 mg of ritonavir once daily with an optimized background therapy of 2 NRTIs for 24 weeks. In countries without locally approved pediatric indication for atazanavir, patients may continue to receive study treatment, with regular 12-week visits, until the age of 18 years. arm 3: Participants with baseline weight ≥ 40 kg received 300 mg of atazanavir plus 100 mg of ritonavir once daily with an optimized background therapy of 2 NRTIs for 24 weeks. In countries without locally approved pediatric indication for atazanavir, patients may continue to receive study treatment, with regular 12-week visits, until the age of 18 years.
