Brief summary
This open label, single arm study will evaluate the PK and PD effects of fenebrutinib in children and adolescents with RMS aged between 10 and \< 18 years. This study consists of a Dose Exploration Period and an Optional Extension Period. Eligible participants may choose to continue treatment with fenebrutinib in the optional extension period after completing the dose exploration period.
Interventions
