Who the study is looking for
- To be eligible to participate in this study, an individual must meet all the following criteria:
- Written and voluntary informed consent.

- Renal function (creatinine level within normal institutional limit, or creatinine clearance \>15 mL/min/1.73 m2 for patients with creatinine levels above institutional normal, calculated using the Cockcroft-Gault formula).
- Liver function (AST/ALT \<3.0 X institutional upper limit of normal OR \< 5 x institutional upper limit of normal in cases of liver metastases; Total bilirubin ≤ 1.5 times ULN.)
- Adequate hematological lab values including
- Absolute Neutrophil Count (ANC) ≥ 1.0 x 109/L
- Platelets ≥ 100 x 109/L
- Hemoglobin ≥ 7.0 g/dL
- Has adequately controlled BP with or without antihypertensive medications, defined as BP ≤150/90 mm Hg with no change in antihypertensive medications within 1 week before randomization/allocation.
