Participants with known Gilbert's syndrome who have total bilirubin level ≤3×ULN may be enrolled. - AST, ALT, and alkaline phosphatase ≤ 2.5 × ULN (if liver metastases are present, then ≤ 5 × ULN is allowed) 9. Acceptable renal function: • Serum creatinine ≤1.5 × ULN, or creatinine clearance ≥50 mL/min as calculated using the modified Cockcroft-Gault equation; confirmation of creatinine clearance is only required when creatinine is >1.5 × ULN; 24-hour urine collection is allowed, but not required 10. Acceptable hematologic status: - Blood transfusion or growth factor support is not allowed within 7 days prior to blood samples that will be used to establish eligibility - Absolute neutrophil count greater than or equal to 1500/mm3. Participants with known Duffy null phenotype who have absolute neutrophil count ≥ 1,200/mm3 may be enrolled - Platelet count greater than or equal to 100,000 mm3 - Hemoglobin greater than or equal to 9 g/dL - Activated partial thromboplastin time (aPTT) ≤1.5×ULN. Study participants on therapeutic doses of anticoagulation medication must have INR and/or aPTT ≤ the upper limit of the therapeutic range for intended use 11.

Women of childbearing potential and men must agree to use adequate contraception prior to study entry, for the duration of study participation and for 7 months (for women) or 4 months (for men) after the last dose of study drug. General

NOTE: Participants with previously treated, clinically stable, radiologically stable brain metastases maybe eligible 5. Pregnant or nursing women 6. Any standard cancer therapy (e.g., chemotherapy, hormonal therapy, radiotherapy, immunotherapy, biologic therapy treatment) or experimental therapy within 4 weeks or 5 half-lives, whichever is shorter, prior to C1D1. The interval may be reduced to 2 weeks for bone-only radiation therapy. Any major surgical procedure within 6 weeks prior to C1D1 7. Participants have not recovered (i.e., improvement to Grade 1 or better) from all acute toxicities from previous therapy, excluding alopecia and vitiligo. If the participant has an ongoing, stable, chronic Grade 2 toxicity they may be eligible after discussion with Sponsor on a case-by-case basis 8. Any clinically significant corneal or retinal abnormality that may increase the risk of eye toxicity 9.

Participants with HCV with undetectable virus after treatment are eligible. Participants with a prior history of hepatitis B virus are eligible if quantitative polymerase change reaction for hepatitis B virus DNA is negative - Participants with human immunodeficiency virus (HIV) infection with acquired immune deficiency syndrome (AIDS) defining illness are not eligible for enrollment; however, participants who have had HIV infection and who have a cluster of differentiation 4 (CD4) + T cell count >350 cells/μL and no history of an AIDS-defining illness are eligible for entry 10. Has an active second malignancy. Note: participants with a history of malignancy that have been completely treated, with no evidence of active cancer for 3 years prior to enrollment, or participants with tumors cured with radiotherapy or surgery with low risk of recurrence (e.g., non melanoma skin cancer, histologically confirmed complete excision of carcinoma in situ) are allowed 11.
