Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects for standard cohorts must be 18-80 years, inclusive, at the time of signing the informed consent;
• 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)
• Subjects who have a body mass index (BMI) of 18-32 kg/m2(inclusive);
• 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;
• 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;

You may not qualify if:

• History of clinically significant hematological, renal, pancreatic, gastrointestinal, hepatic, cardiovascular, metabolic, endocrine, immunological, allergic disease, or other major disorders
• History of clinically significant abnormal chest x-ray
• Clinically significant neurologic disorder
