- Healthy was defined as having no clinical relevant abnormalities identified by a
detailed medical history, physical exam, blood pressure and pulse rate measurements,
12-lead electrocardiogram, and clinical laboratory tests.

- Body mass index of ≥ 18 and ≤ 30 kilograms (kg)/meter squared and weight of ≥ 50 kg
and ≤ 100 kg.

- Regular daily bowel movements (that is, production of at least 1 stool per day).

millisieverts in the last year prior to screening.

- Clinically significant laboratory abnormalities at screening or Day -1, as well as
absolute neutrophil counts, platelets, and hemoglobin outside of reference ranges.
