Inclusion criteria
Inclusion criteria: - Male or female participants: a. Pediatric formulation group: >=1 and less than 18 years of age at study entry. b. Adult formulation group: >=14 and less than 18 years of age and body weight of >= 40 kg at study entry. - Participants must meet all of the following laboratory values at the screening visit.
