- Ability to provide informed consent and/or consent obtained from a legally acceptable representative (as required by IRB), prior to the initiation of any protocol-required procedures.
- Male and female subjects who are surgically sterile, female subjects who have been postmenopausal for at least 12 consecutive months prior to the screening visit, or male subjects/female subjects (of childbearing potential) who agree to remain abstinent or to practice 2 of the approved birth control methods from the screening visit and for at least 150 days after the dose of IMP for a female subject or 180 days after the dose of IMP for a male subject.
Exclusion Criteria:
- Subjects who have:
- Met DSM-V criteria for substance use disorder within the past 180 days; including alcohol and benzodiazepines, excluding caffeine/nicotine.
- A positive drug screen for drugs of abuse (excluding stimulants, other prescribed medications, and marijuana [if in investigator's documented opinion the subject does not meet DSM-V criteria for substance use disorder]).
