Outcome Measures
Primary Outcomes (4)
Number of Participants Who Died and With Adverse Events (AEs) Leading to Discontinuation, Hyperbilirubinemia, Jaundice, First-degree Arterioventricular Block, Tachycardia, and Rash on ATV Powder
AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment.
Day one to week 300 (approximately 22-Jan-2018)
Number of Participants Who Experienced a SAE on ATV Powder
SAE= any of the the following: is life-threatening (defined as an event in which the subject was at risk of death at the time of the event; it does not refer to an event which hypothetically might have caused death if it were more severe), requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is an important medical event (defined as a medical event(s) that may not be immediately life threatening or result in death or hospitalization but, based upon appropriate medical and scientific judgment, may jeopardize the subject or may require intervention \[eg, medical, surgical\] to prevent one of the other serious outcomes listed in the definition above.) Examples of such events include, but are not limited to, intensive treatment in an emergency room or at home for allergic bronchospasm; blood dyscrasias or convulsions that do not result in hospitalization
Day one to week 300 (approximately 22-Jan-2018)
Number of Participants With A Center of Disease Control and Prevention (CDC) Class C AIDS Event on ATV Powder
The CDC disease staging system assesses the severity of HIV disease by CD4 cell counts and by the presence of specific HIV-related conditions. CD4 counts are classified as 1: ≥500 cells/µL, 2: 200-499 cells/µL, and 3: \<200 cells/µL. Children with HIV infection are also classified in each of several categories. Category N: Not symptomatic. Category A: Mildly symptomatic. Category B: Moderately symptomatic. Category C: Severely symptomatic.
Day one to week 300 (approximately 22-Jan-2018)
Number of Participants With Laboratory Test Results Meeting the Criteria for Grade 3-4 Abnormality on ATV Powder
Criteria of the Division of AIDS for grading the severity of adult and pediatric adverse events as follows: Grade (Gr) 1=mild; Gr 2=moderate; Gr 3=severe; Gr 4=potentially life-threatening. Neutrophils (absolute) (adult and infants \>7 days): Gr 1=1.000-1300/mm\^3; Gr 2=750-999 mm\^3; Gr 3=500-749 mm\^3; Gr 4= \<500 mm\^3. Alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase: Gr 1=1.25-2.5\*upper limit of normal (ULN); Gr 2=2.6-5.0\*ULN; Gr 3=5.1-10.0\*ULN; Gr 4= \>10.0\*ULN. Bilirubin, total (adults and infants \>14 days): Gr 1=1.1-1.5\*ULN; Gr 2=1.6-2.5\*ULN; Gr 3=2.6-5.0\*ULN; Gr 4= \>5.0\*ULN. Lipase: Gr 1=1.1-1.5\*ULN; Gr 2=1.6-3.0\*ULN; Gr 3=3.1-5.0\*ULN; Gr 4= \>5.0\*ULN. Bicarbonate, serum low: Gr 1=16.0 mEq/L-\<lower limit of normal; Gr 2=11.0-15.9 mEq/L; Gr 3=8.0-10.9 mEq/L; Gr 4= \<8 mEq/L. By criteria of the World Health Organization: Amylase: Gr 1=1.0-1.39\*ULN; Gr 2=1.40-2.09\*ULN; Gr 3.=2.10-5.0\*ULN; Gr 4= \>5.0\*ULN.
Day one to week 300 (approximately 22-Jan-2018)

Study Arms (1)
Stage 1: Atazanavir + Ritonavir
EXPERIMENTALParticipants received atazanavir powder orally (dosed by weight: 5 to \<10 kg=150 mg, 5 to \<10 kg=200 mg, 10 to \<15 kg=200 mg, 15 to \<25 kg=250 mg, 25 to \<35 kg=300 mg) once daily for 24 to 48 weeks or a weight ≥35 kg.
