• A Body Mass Index (BMI) of 19 to less than 28 kg/m2 and a body weight of at least 45 kg.
• Negative anti-nuclear antibody (ANA) test; or positive with dilutions not greater than 1:40 and with no associated history or symptoms of potential connective tissue disease or other immune-mediated diseases.
• Women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods.
• Men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and refrain from donating sperm.
• Negative pregnancy test on Day -1 for female participants.
• Non-smokers, or use of < 10 cigarettes (or equivalent nicotine-containing product) per day.

Exclusion Criteria

Eye drop-containing and infrequent inhaled corticosteroids are permissible up to 4 weeks prior to the first dose of study drug.
• History of clinically significant thyroid disease; also, subjects with clinically significant elevated thyroid-stimulating hormone (TSH) concentrations at Screening.
• Any confirmed clinically significant allergic reactions (anaphylaxis) against any drug, or multiple drug allergies (non-active hay fever is acceptable).
• Abnormal renal function.
• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) values at Screening above ULN and judged clinically significant by the Investigator.
• Positive results for anti-mitochondrial antibody (AMA), anti-smooth muscle antibody (ASMA) or thyroid peroxidase antibody.
