Eligibility

Recruits 219 The protocol indicates a vulnerable population selection flag and restricts enrollment to participants capable of giving signed informed consent. Inclusion criteria require participants be 'capable of giving signed informed consent' and exclude those with evidence of impaired capacity (e.g., Wernicke-Korsakoff syndrome or alcohol-related dementia). Consent is obtained from the adult participant (no pediatric assent process described). Additional consent elements include pregnancy testing for women of childbearing potential and specific ICFs (main, restart, genetic, optional studies)..

Pregnancy Exclusion
Main Study Period A female participant is eligible to participate, if she is not pregnant or breastfeeding and one of the following conditions applies: INC#5 − Is a woman of nonchildbearing potential (WONCBP) as defined in Section 10.4 (Appendix 4: Contraceptive and barrier guidance). OR – Is a WOCBP and using a contraceptive method that is highly effective, with a failure rate of <1%, as described in Section 10.4. Contraceptive measures must start at least 28 days prior to the first dose of study intervention and should continue during the study intervention period, for a minimum of 18 weeks after the last dose of study intervention. 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 or urine as required by local regulations) within 24 hours before the first dose of study intervention (see Section 8.3.5 Pregnancy testing).
