Arm Intervention/treatment
Experimental: EBR/GZR
Ages 12 to less than 18 years will receive Fixed Dose Combination (FDC) EBR/GZR tablets once daily for 12 weeks; and ages 3 to less than 12 years will receive a pediatric formulation of EBR/GZR once daily for 12 weeks. There will be 24 weeks of follow-up.
Drug: EBR/GZR
Ages 12 to less than 18 years will receive oral FDC tablets with EBR 50 mg/GZR 100 mg once daily. Ages 3 to less than 12 years will receive oral granules pediatric formulation in a soft food vehicle once daily with EBR/GRZ not to exceed 50 mg/100 mg.
