Eligibility Criteria

        Inclusion Criteria:

          -  Histological diagnosis of un-resectable or metastatic colorectal cancer which is KRAS
             and NRAS mutation negative (wild-type). Patients with any known mutation in KRAS or
             NRAS codons 12, 13, 59, 61, 117 or 146 will be excluded. Mutations of KRAS and NRAS
             codons not listed above are allowed. Biopsy of metastatic lesion is not required.

          -  Patients must show signs of progression (by imaging, or tumor marker elevation) after

          -  Prior use of regorafenib.

          -  Known or suspected grade 3 allergy or hypersensitivity to any of the study drugs,
             study drug classes, or excipients of the formulations given during the course of the

          -  Uncontrolled hypertension (systolic pressure greater than140 mm Hg or diastolic
             pressure greater than 90 mm Hg [NCI-CTCAE v4.0] on mean of 3 consecutive readings
             despite optimal medical management. Hypertension may be corrected by adding or
             adjusting anti-hypertensives prior to the initiation of treatment at the discretion of
             the practitioner.

          -  Active or clinically significant cardiac disease including congestive heart failure,
             uncontrolled cardiac arrhythmias, or unstable angina.

          -  Any hemorrhage or bleeding event greater than or equal to NCI CTCAE v.4.0 Grade 3
             within 4 weeks prior to start of study medication.

          -  Subjects with thrombotic, embolic, venous, or arterial events, such as cerebrovascular
             accident (including transient ischemic attacks) deep vein thrombosis or pulmonary
             embolism that have initiated within 6 months of start of study treatment. Stable,

             a random urine sample. If the result is normal then no additional testing is required.
             If the result is abnormal, a 24 hour urine will be collected to determine if
