Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participant must be of first to third generation Japanese descent

Any abnormalities, must be considered not clinically significant and this determination must be recorded in the participant's source documents and initialed by the investigator
• Participant must be otherwise healthy on the basis of clinical laboratory tests performed at screening and Day-1. If the results of the serum chemistry panel including hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
• Participant must have a body mass index (BMI) between 18 and 30 kilogram per meter square (kg/m^2) (BMI = weight/height^2) and a body weight of between 50 to 90 kg inclusive
