10. LVEF greater than or equal to 50% or greater than or equal to LLN for the institution based on multiple gated acquisition scan (MUGA) or echocardiogram (ECHO).

    Specific to Phase I:
11. Recurrent, advanced, or metastatic cancer that is known to be potentially responsive to treatment with fluoropyrimidines or oxaliplatin. Examples include gastrointestinal tumors, HER2 (ErbB2)-positive breast cancer, and lung cancers.
12. Received less than or equal to 3 prior chemotherapy regimens without pelvic radiotherapy or less than or equal to 2 prior chemotherapy regimens if received pelvic radiotherapy.

15. Archived paraffin-embedded tumor tissue must be available for biomarker analysis.
16. Platelet count greater than or equal to 100,000/mm\^3 (100 x 109/L).

Exclusion Critera:

1. Pregnant or lactating female.
2. Prior resection of the small bowel.
3. Brain metastases that require additional treatment.
4. Medically unfit for the study as a result of the medical interview, physical exam, or screening investigations.
5. Taking any medication on the prohibited medications list (see Section 9.2).
6. History of drug or other allergy, which, in the opinion of the Investigator, contraindicates participation.
7. Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the study drugs. These include other anilinoquinazolines, such as gefitinib \[Iressa\], or erlotinib \[Tarceva\]. The subject has received treatment with any investigational drug in the previous four weeks.
8. Treatment with any biologic, cytotoxic, radiation , or hormonal (other than for contraception or replacement) therapy within four weeks. Treatment with hormones with short half-lives is allowed up to 1 week prior to study treatment after consultation with GSK medical monitor.
9. Major surgery within the previous two weeks unless in the opinion of the Investigator, the subject has recovered sufficiently to begin study treatment.
10. Physiological, familial, sociological, or geographical conditions that do not permit compliance with the protocol.
11. Receiving concurrent coumadin therapy. Minidose coumadin for maintenance of catheters (0.5 to 1.0 mg/day), and other anticoagulation therapy are allowed on study. Subjects receiving minidose coumadin must have prothrombin time (PT) or International normalized ratio (INR) and partial thromboplastin time (PTT) within 1.2 times the ULN.

timeFrame: Plasma TS mRNA is collected at screening. Pre-treatment tumor sample can be archived tissue if collected within 5 years from screening; if not, tumor sample should be collected at screening.

timeFrame: Blood samples were collected to determine TS levels at screening phase; Days 43 and 85; after every 2 cycles of treatment (+/- 3 days); and at discontinuation (if possible).
measure: Tumor-derived Biomarkers (Encoded in Protein or RNA) Associated With Clinical Outcome to Treatment
timeFrame: Pre-treatment tumor sample should have been provided for the most recent biopsy (not older than 5 years) prior to dosing. The post-treatment sample is suggested, not mandatory, and should have been collected at 43 +/-3 days.
measure: Genetic Aberrations in Somatic (Tumor) DNA Derived From the Tumor Tissue Biopsies That May Associate With Clinical Outcomes in Response to Therapy
timeFrame: Pre-treatment tumor sample should have been provided for the most recent biopsy (not older than 5 years) prior to dosing. The post-treatment sample is suggested, not mandatory, and should have been collected at end of Cycle 2, +/-3 days from Cycle 3.
measure: Genetic Variants in Germline (Host) DNA and Comparison to the Efficacy and Safety of the Study Drugs
timeFrame: Optional pharmacogenetics sample may be collected at any time during the study after consent has been obtained; however, it is recommended that it be collected at the earliest time point possible
