6. Post-menopausal females with amenorrhea for at least 12 months with a serum follicle
stimulating hormone [FSH] level of >40 IU/L) or women of non-childbearing potential
(WONCBP) who are permanently sterilized (bilateral tubal ligation, hysterectomy,
bilateral oophorectomy for six months minimum prior to screening).

7. Non-pregnant females of childbearing potential who are either sexually inactive
(abstinent) or, if sexually active with a male partner who is biologically capable of
having children, agree to use one of the following acceptable birth control methods
beginning 14 days prior to the first dose, throughout the study, and for 30 days
following the last dose:

- Hormonal contraceptive (i.e., oral, transdermal/subdermal; implant or injection)

- Intrauterine device (IUD)

- Double contraceptive methods (e.g. oral contraception and condom)

- Vasectomized partner (6 months minimum)

8. Male subjects who are biologically capable of having children (i.e., non-vasectomized)
who are sexually inactive (abstinent) or, if sexually active with a female of
childbearing potential, must agree to use one or more of the above forms of birth
control for themselves and their partner(s), as appropriate, beginning 14 days prior
to the first dose through at least 90 days following the last administration of study
drug. They must also agree to abstain from sperm donation from the first
administration of study drug to 90 days after the last administration of study drug.

suicidal thoughts, or more than one lifetime suicide attempt) within six months before
Screening, or at Screening and Day -1 as determined by C-SSRS.

3. Evidence of infection with Hepatitis B or C, or human immunodeficiency virus HIV-1 or
HIV2, as determined by results of testing at screening.

4. Positive urine drug screen (for amphetamines, methamphetamines, methadone,
barbiturates, benzodiazepines, cocaine, opiates, methylenedioxymethamphetamine,
