6. History of taking any neurotoxic drugs within 6 months of Screening.
7. Current use of drugs that are used to treat neuropathic pain (eg, gabapentin, pregabalin, and duloxetine) within 30 days of Screening.
8. Current diagnosis of malignancy other than breast cancer.
9. Absolute neutrophil count <1.5 x 109 cells/L.
10. Platelet count <100,000 x 109/L.
11. Hemoglobin level <9 g/dL at Screening without transfusion (transfusion independent).
12. Corrected QTcF >470 msec (single tracing) at Screening and prior to randomization.
13. Chronic renal or hepatic disease.
14. Clinically significant renal dysfunction including serum creatinine level >1.5 mg/dL or calculated creatinine clearance ≥50 mL/minute at Screening.
15. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level >2.0 x upper limits of normal (ULN), or a bilirubin >1.5 x ULN unless in the setting of known Gilbert's disease at Screening.
16. History of HIV, hepatitis B, hepatitis C, or tuberculosis.
17. Major surgical procedures ≤30 days prior to starting study drug, or minor surgical procedures ≤7 days prior to starting study drug.
