Part A: LUM/IVAIVAParticipants weighing 7 to less than (\<)10 kilograms (kg) at screening received LUM 75 milligrams (mg)/IVA 94 mg fixed-dose combination (FDC) every 12 hours (q12h) and those weighing 10 to \<14 kg at screening received LUM 100 mg/IVA 125 mg q12h for 15 days. Participants weighing greater than or equal to (\>=)14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 15 days.
Part B: LUM/IVAIVAParticipants weighing 7 to \<9 kg at screening received LUM 75 mg/IVA 94 mg FDC q12h and those weighing 9 to \<14 kg received LUM 100 mg/IVA 125 mg q12h for 24 weeks. Participants weighing \>=14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 24 weeks. Doses were adjusted upwards for changes in weight.
Part B: LUM/IVALUMParticipants weighing 7 to \<9 kg at screening received LUM 75 mg/IVA 94 mg FDC q12h and those weighing 9 to \<14 kg received LUM 100 mg/IVA 125 mg q12h for 24 weeks. Participants weighing \>=14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 24 weeks. Doses were adjusted upwards for changes in weight.
Part A: LUM/IVALUMParticipants weighing 7 to less than (\<)10 kilograms (kg) at screening received LUM 75 milligrams (mg)/IVA 94 mg fixed-dose combination (FDC) every 12 hours (q12h) and those weighing 10 to \<14 kg at screening received LUM 100 mg/IVA 125 mg q12h for 15 days. Participants weighing greater than or equal to (\>=)14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 15 days.
