Must agree to use contraception as detailed in Appendix 5 of this protocol during the treatment period and for at least 90 days after dosing of study treatment and refrain from donating sperm during this period Be first generation Japanese. Exclusion Criteria: Has a history of or current clinically significant medical illness that the investigator considers should exclude the subject or that could interfere with the interpretation of the study results. Clinically significant abnormal values for hematology, clinical chemistry, or urinalysis at screening and Day -1 as deemed appropriate by the investigator Clinically significant abnormal physical examination, vital signs or 12 lead ECG at screening and Day -1 as deemed appropriate by the investigator Has donated blood or had a significant blood loss (≤500 mL) within 8 weeks of Day 1 or history of anemia or history of decreased red blood cells (RBC). Donated plasma within 7 days of Day -1 Estimated creatinine clearance <80 mL/min Liver function tests (serum alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and serum bilirubin (total and direct) 1.2 times above the upper limit of normal (ULN) at Screening or Day -1. Baseline hemoglobin, hematocrit, red blood cell count below the lower limit of normal at Screening and Day -1. Has a history of human immunodeficiency virus (HIV) antibody positive, or tests positive for HIV; has a history of hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or other clinically active liver disease, or tests positive for HBsAg or anti-HCV at Screening. History of drug or alcohol abuse according to Diagnostic and Statistical Manual of Mental Disorders (4th edition) criteria within 5 years before screening or positive test result(s) for alcohol and/or drugs of abuse at screening and Day -1.
