Eligibility criteria:

        Inclusion Criteria:

          1. ≥ 18-year-old males or females

          2. Histologically or cytologically confirmed metastatic colorectal cancer or other
             gastrointestinal malignancy for which FOLFOX6 chemotherapy is a standard treatment.
             Other gastrointestinal cancers include, but are not limited to, esophageal, gastric,
             and small intestine, appendiceal, and pancreatico-biliary cancers.

          3. Documented progressive disease

          4. Measurable or evaluable disease by RECIST. (Note: Subjects enrolled in the MTD
             Expansion Cohort are required to have measurable disease, according to RECIST.)

          5. No more than 2 prior chemotherapy regimens for metastatic disease (This does not
             include prior adjuvant chemotherapy with fluorouracil and/or oxaliplatin.)

          6. At least 3 weeks since prior treatment with:

               -  Chemotherapy (at least 6 weeks for nitrosoureas, mitomycin C, and liposomal
                  doxorubicin)

               -  Agents targeting the VEGF pathway (eg, bevacizumab, sunitinib, sorafenib, etc.)

               -  Other signal transduction inhibitors and monoclonal antibodies

               -  Immunotherapy or biological response modifiers

               -  Systemic hormonal anti-cancer therapy, with the exception of LHRH agonists for
                  prostate cancer

               -  Any experimental therapy

          7. Resolution of toxicities associated with prior chemotherapy to ≤ Grade 1 (except for
             Grade 2 alopecia)

          8. ECOG performance status ≤ 2 (see Appendix A) and life expectancy ≥ 3 months

          9. No childbearing potential or use of effective contraception by all fertile male and
             female subjects during the study and for 30 days after the last dose of study drug.
             All subjects must agree to use a highly effective method of contraception (including
             their partner). Effective birth control includes (a) IUD plus one barrier method; or
             (b) 2 barrier methods. Effective barrier methods are male or female condoms,
             diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm).
             Oral, implantable, or injectable contraceptives may be affected by cytochrome P450
             interactions, and are therefore not considered effective for this study.
