Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Between 18 and 50 years of age inclusive, at the time of signing the informed consent.

A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: Is a woman of non-childbearing potential (WONCBP) OR Is a woman of childbearing potential (WOCBP) and using an acceptable contraceptive method from 30 days prior to first dose until follow up visit. The investigator should evaluate the potential for contraceptive method failure (e.g., noncompliance, recently initiated in relationship to the first dose of study intervention). A WOCBP must have a negative highly sensitive pregnancy test (serum) at screening and on admission to the clinical unit. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.

- Any history of suicidal behavior within the past 6 months or any history of attempted suicide in a participant's lifetime.
- Alanine transaminase (ALT) >1.5 times upper limit of normal (ULN).
- Bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percent).

- For Part C only, history of liver toxicity resulting from drug administration.
- For Part C only, history of intolerance to itraconazole.
