DDI Study of Evobrutinib and Carbamazepine

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to investigate the effect of multiple doses of carbamazepine on two single doses of evobrutinib pharmacokinetics (PK) in healthy participants. Study details include: Study Duration: up to 54 days. Treatment Duration: 25 days. Visit Frequency: Participants will be resident in the Clinical Research Unit from Day 1 to Day 20 and return on Day 26 for a Safety Follow-Up visit.

Administration of other types of vaccines (e.g., SARSCoV2 vaccines) is allowed until 2 weeks before admission to Clinical Research Unit (CRU), thereafter it is prohibited until the end of the study Moderate or strong inhibitors or inducers of Cytochrome P450 (CYP)3A4/5 or Pgp within 4 weeks prior to the first administration of study intervention Contraindication to carbamazepine (carbamazepine SmPC) History of any malignancy History of drug hypersensitivity ascertained or presumptive allergy/hypersensitivity to the active drug substance and/or formulation ingredients; history of serious allergic reactions leading to hospitalization or any other hypersensitivity reaction in general, including contact hypersensitivity to Electrocardiogram (ECG) electrodes, which may affect the safety of the participant and/or outcome of the study per the Investigator's discretion. Other protocol defined exclusion criteria could apply.
