Eligibility
Key inclusion criteria
1. Subjects for standard cohorts must be 18-80 years, inclusive, at the time of signing
the informed consent;

2. Subjects who are in good general health with no clinically relevant abnormalities
based on the medical history, physical examinations, neurological examinations,
clinical laboratory evaluations (hematology and clinical chemistry)

3. Subjects who have a body mass index (BMI) of 18-32 kg/m2(inclusive);

4. Male subjects are eligible to participate if they are rendered surgically sterile (at
least 6 months), or agree to the following during the study and for at least 30 days
after the last dose of study drug:

• Refrain from donating sperm;

AND, either:

- Be abstinent from heterosexual intercourse as their preferred and usual lifestyle
(abstinent on a long term and persistent basis) and agree to remain abstinent; OR

- Agree to use a male condom (contraception/barrier) and should also be advised of
the benefit for a female partner to use an acceptable, highly effective method of
contraception as a condom may break or leak when having sexual intercourse;

5. Female subjects are eligible to participate if they are not pregnant or breastfeeding,
subject to one of the following:

- Women of childbearing potential (WOCBP), defined as women physiologically capable
of becoming pregnant, must have a negative serum pregnancy test at the Screening
visit and a negative urine pregnancy test on Day -1; WOCBP must agree to use an
acceptable, highly effective contraceptive method from Screening until 30 days
after the last dose of study treatment (see Section 11.3); OR

- Menopausal women must have an elevated serum follicle-stimulating hormone level
(FSH) level at Screening; if the FSH is not elevated, they are considered to be
of childbearing potential (unless permanently sterile) and must have a negative
serum pregnancy test at Screening and a negative urine pregnancy test on Day -1;
