7. Body mass index (BMI) within the range 18.5 â?? 30 kg per m2 (inclusive) at screening and baseline.

8. Life expectancy of greater than or equal to 12 weeks at screening and baseline.

9. Participants if have received radiotherapy (regardless of site & dose), a gap of 28 days must be maintained between the last dose of radiotherapy and baseline.

10. Participant with adequate hematologic, liver and renal function at screening and/or baseline as defined in schedule of assessments. Bone marrow function: ANC greater or equal to 1500 per mm3 without granulocyte colony-stimulating factor support at screening and at baseline, Platelet count greater or equal to 100,000 per mm3 without transfusion at screening and at baseline, Hemoglobin greater or equal to 9 g per dL without erythropoietin dependency and without packed red blood cell transfusion at screening and at baseline.

The investigator should evaluate the effectiveness of the contraceptive

Exclusion Criteria

Any potential participant who meets any of the following criteria will be excluded from participating in the study:

NOTE: Participants with planned minor surgical procedures to be conducted under local anesthesia may participate.

5. 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.
