Patient is judged to have no unmanaged significant disease or disorder based on medical history, physical examination, vital sign measurements, and laboratory safety obtained at pre-study/screening, and within 36 hours prior to first administration of study drug.
Patient has no clinically significant abnormality of ECG performed at pre study/screening, and prior to first administration of study drug.
Patient is willing to undergo the nutrient volume tolerance tests.

Patients with an actual or calculated creatinine clearance that is in the range of 72-79 mL/min (i.e., within 10% of 80 mL/min) may be enrolled in the study at the discretion of the Investigator.
