• Positive urine drug or alcohol results

• Estimated creatinine clearance in non-elderly subjects <80 mL/min at screening and in elderly subjects (i.e., ≥55 years of age) <60 mL/min at screening

• Hemoglobin value of less than 11.5 g/dl for females, 13.0 g/dl for males at screening and first check-in

• Any of the following drugs for 28 days prior to the first dose of study drug in Treatment Period 1 and throughout the study:
