Group Intervention Description CTP-543 and Fluconazole Treatment CTP-543 On Day 1, each subject will receive a single oral dose of 12 mg CTP-543. Following a washout on Day 2, each subject will receive an oral dose of 200 mg fluconazole once daily on Days 3 through to Day 8. On Day 7, approximately 1 hour after the 200 mg dose of fluconazole, each subject will receive a single oral dose of 12 mg CTP-543. CTP-543 and Fluconazole Treatment Fluconazole On Day 1, each subject will receive a single oral dose of 12 mg CTP-543. Following a washout on Day 2, each subject will receive an oral dose of 200 mg fluconazole once daily on Days 3 through to Day 8. On Day 7, approximately 1 hour after the 200 mg dose of fluconazole, each subject will receive a single oral dose of 12 mg CTP-543.
