             evidence of any active or chronic disease following a detailed medical and surgical
             history, as well as a complete physical examination including vital signs, 12-lead

             body weight greater than or equal to (≥) 45 kg (99 pounds [lbs]). This inclusion
             criterion will only be assessed at the screening visit.

          -  Willing and able to consume standardized meals during the confinement period of the
             study. All subjects will be required to consume the identical meals on study days when

          -  Current or relevant history of physical or psychiatric illness, any medical disorder
             that may require treatment or make the subject unlikely to complete the study, or any
