Eligibility
Recruits 1358 paediatric patients.
- Vulnerable Population
- The trial selects vulnerable populations (isVulnerablePopulationSelected = true) and permits inclusion of adolescents aged 16 to <18 years where locally allowed (must meet Tanner Stage 5). Age-specific information and consent/assent documents are provided (e.g. L1_SIS and ICF_Adolescent, L1_SIS and ICF_Parent, Pediatric Assent and Parent ICF documents are included). Minors require assent and involvement of parent/legal representative as per country-specific procedures; documents exist in multiple country/language variants.
