  • Healthy participants. Healthy status is defined by the absence of evidence of any active or chronic disease following a detailed medical and surgical history, a complete physical examination including ophthalmological examination, vital signs, 12-lead electrocardiogram (ECG), hematology, blood chemistry, serology and urinalysis
  • A body mass index (BMI) between 18 to 30 kilograms per square meter (kg/m^2) inclusive

  • Female participants must be either surgically sterile or post-menopausal

Exclusion Criteria:

  • Medical history of cardiovascular disease, renal disease, liver disease, digestive system disease, blood dyscrasia, immunologic disease, diseases of the nervous system, endocrine disease, metabolic disease, lung disease, or with anamnesis and obstacles in kidney, liver, or cardiopulmonary function

  • Positive result for human immunodeficiency virus (HIV) antigen and antibody, hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV) antibody at screening
  • Donation or loss of blood over 500 milliliters (mL) within three months prior to screening
