* ALT, AST or alkaline phosphatase (ALP) > 1.5 times the upper limit of normal (ULN)
* Calculated creatinine clearance < 80 mL/min
* Haemoglobin (Hb) outside of the normal range
* Platelet count <125 x 109/L
* Serum potassium outside of the normal range
* White blood cell (WBC) count outside of the normal range
* Thyroid stimulating hormone (TSH) outside of the normal range
* Any other clinically significant abnormal lab values, as determined by the Clinical Investigator.
