Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - IVA

Experimental: Part A: 3 to <24 months - Participants weighing 5 to less than (<) 7 kilogram (kg) received 25 milligram (mg) IVA, 7 to <14 kg received 50 mg IVA, and those weighing 14 to <25 kg received 75 mg IVA administered every 12 hours (q12h) on Days 1 through 3 and 1 morning dose on Day 4.

Experimental: Part B + A/B:1 to < 24 months - Participants 4 to <6 months of age and weighing greater than or equal to (=) 5 kg received 25 mg IVA q12h. At 6 months of age and older, participants weighing 5 to <7 kg received 25 mg IVA, 7 to <14 kg received 50 mg IVA, and those weighing 14 to <25 kg received 75 mg IVA q12h for 24 weeks on Part B. For Part A/B, participants 1 to <4 months weighing 3 kg to <5 kg received an initial low dose of 5.7 mg q12h IVA and those weighing =5 kg received 11.4 mg q12h IVA for the first 15 days of IVA treatment. Doses were maintained or adjusted upward at Day 15 and based on weight and/or age once they reached 4 months of age.

confound the results of the study or pose an additional risk in administering study
drug to the participant

at screening (Only for Parts A and B)

- History of abnormal liver function or abnormal liver function at screening

screening

- Hemoglobin (Hgb) <9.5 g/dL at screening
