Más betegség

• History of previous malignancy within the last 5 years except basal cell carcinoma or carcinoma in situ in solid organ.

• Must have a Child-Pugh A status for Phase 1a and a Child-Pugh A or B status for Phase 1b and 2a. SRC discretion to restrict to Child-Pugh A status for Phase 1b and 2a.
• Must have an ECOG performance status of 0 or 1 at Screening.
• Must have life expectancy of > 12 weeks in the investigator's opinion.
• Must have ALT and AST ≤ 5.0 × upper limit of normal (ULN) at Screening.
• Must have total bilirubin (TBil) ≤ 3.0 mg/dL at Screening.
• Must have adequate renal function with estimated creatinine clearance
