             not be amenable to surgical resection or radiation with curative intent.

          -  Documented disease progression at study entry

          -  Must have received at least 1 chemotherapy regimens in the setting of metastatic
             disease

          -  Eastern Cooperative Oncology Group (ECOG) performance status of ≤2

          -  Adequate hematological function: Absolute neutrophil count (ANC) > 1500/mm^3,
             platelets count >100,000mm^3

          -  Adequate hepatic function within 14 days prior to Cycle 1 Day 1 (C1D1): total
             bilirubin <2 times the upper limit of normal (ULN) (except patients with Gilbert's
             syndrome who must have a total bilirubin of < 3 times ULN) and aspartate
             aminotransferase (AST), alanine aminotransferase (ALT) ≤2.5 x ULN. In the case of
             known (radiological and/or biopsy documented) liver metastasis, AST/ALT ≤5.0 times ULN
             is acceptable.

          -  Amylase and lipase ≤ 1.5 x ULN

          -  Adequate renal function within 14 days prior to C1D1: estimated creatinine clearance
             of ≥ 30 mL/min

          -  Women of child-bearing potential (WOCBP) must agree to use dual methods of
             contraception and have a negative serum pregnancy test at screening, and male
             participants must use an effective barrier method of contraception if sexually active
             with a female of child-bearing potential. For both male and female participants,
             effective methods of contraception must be used throughout the study and for 3 months
             following the last dose. To be considered of non-childbearing potential,
             postmenopausal women must be amenorrheic for at least 12 months naturally (not in the
             setting of post chemotherapy) or participants must be surgically sterile.

             contraindicated

        Exclusion Criteria:

          -  Significant medical illness that in the investigator's opinion cannot be adequately
             controlled with appropriate therapy or would compromise the participant's ability to
             tolerate this therapy

          -  Women who are pregnant or lactating

          -  Radiation, chemotherapy, or immunotherapy or any other approved anticancer therapy ≤2
