Drug

Participants received a single oral dose of Evobrutinib 45 mg on Day 1 and Day 19

Other names: M2951

carbamazepine

Drug

Participants received Carbamazepine 100 mg on Days 2 and 3, 200 mg on Days 4 and 5 and then 300 mg from Days 6 to 19 and were titrated back to 200 mg from Days 20 to 22 and 100 mg on Days 23 to 25 twice daily.
