  • History or presence of alcohol or drug abuse within the past 2 years prior to the first dosing
  • Presence or history of significant gastrointestinal, liver or kidney disease, or any other condition that is known to interfere with drug absorption, distribution, metabolism or excretion, or known to potentiate or predispose to undesired effects
  • History of prolonged QT syndrome or a QTc interval with Fridericia's correction (QTcF) \> 450 msec for males or QTcF \> 470 msec for females at screening visit or prior to the first dosing
  • Abnormal liver function at screening
  • Females who are nursing, pregnant, or planning to become pregnant while in the study, and for 30 days after last dose of study drug
  • Positive results for coronavirus infection (COVID-19) at screening or check-in
  • Positive drug or alcohol results at screening or check-in

  • Participation in another clinical study within 30 days prior to, and 30 days after the first dosing.

Arms & Interventions

CTP-543

Subjects will receive a single 2 mg dose of midazolam on Day 1. Starting on Day 3, 12 mg dose of CTP-543 will be administered (q12 hrs) for 14 consecutive days (up to Day 16). On Day 16, subjects will be co-administered a single 2 mg midazolam dose along with the morning dose of CTP-543. The second dose of CTP-543 will be administered as scheduled on Day 16.

Intervention: Midazolam

CTP-543

Subjects will receive a single 2 mg dose of midazolam on Day 1. Starting on Day 3, 12 mg dose of CTP-543 will be administered (q12 hrs) for 14 consecutive days (up to Day 16). On Day 16, subjects will be co-administered a single 2 mg midazolam dose along with the morning dose of CTP-543. The second dose of CTP-543 will be administered as scheduled on Day 16.

Intervention: CTP-543
