Eligibility criteria:

        Inclusion Criteria:

          1. Histologically confirmed stage IIIB/IV or relapsed non-small cell lung carcinoma
             (squamous carcinoma, adenocarcinoma, or large cell carcinoma). Patients with mixed
             tumors with small-cell elements are ineligible.

          2. Patients with no more than 2 prior lines of therapy, with the latest of those
             therapies being single-agent erlotinib.

          3. Evidence of progressive disease on erlotinib as assessed by the treating physician.
             Erlotinib must be the last treatment for NSCLC prior to enrollment into this study.
             Patients may be on erlotinib until enrollment. If erlotinib has already been stopped,
             the period of time off Erlotinib cannot exceed 14 days prior to study enrollment.

          4. Patients must have experienced a clinical benefit (complete response [CR], partial
             response [PR], or stable disease [SD]) from prior therapy with erlotinib for a period
             of 8 weeks.

          5. Patient must have one measurable lesion measuring at least 10 mm in the longest
             diameter (LD) by spiral computed tomography (CT), or 20 mm with conventional
             techniques according to the Response Evaluation Criteria in Solid Tumors (RECIST).

          6. Recovery from any toxic effects of erlotinib to ≤ grade 1 per the National Cancer
             Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE).

          7. Completion of palliative radiation therapy prior to the start of study treatment.
             Previously irradiated lesions in the advanced setting cannot be included as target
             lesions unless clear tumor progression has been observed following the completion of
             radiation therapy.

          8. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

          9. Absolute neutrophil count (ANC) >=1,500 and platelets >=75,000 (within 7 days prior to
             initial study treatment).

         10. Hemoglobin >=9 g/dL (within 7 days prior to initial treatment).

         11. International normalized ratio (INR) <=1.5 or prothrombin time (PT)/partial
             thromboplastin time (PTT) within normal limits (WNL) of the institution if not on
             anticoagulation therapy. Patients receiving anti-coagulation treatment with an agent
             such as warfarin or heparin may be allowed to participate with the therapeutic range
             established prior to study treatment initiation.

         12. Serum creatinine <=1.5 x institutional upper limit of normal (ULN) within 7 days prior
             to initial study treatment. If the absolute value is greater than 2mg/dL, the
             creatinine clearance, calculated according to the Cockroft-Gault formula, must be >=45
             mL/min to be eligible.

         13. Bilirubin <=1.5 x the ULN; transaminases <=3 x institutional ULN, except in known
             hepatic metastasis, wherein these may be >=5 x institutional ULN.

         14. Patients must be able to understand the nature of this study, give written informed
             consent, and comply with study requirements.

         15. Agreement of male patients (with partners of childbearing potential) and female
             patients of childbearing potential to use effective contraception to prevent pregnancy
             during treatment and for a minimum of 90 days thereafter. Additionally, women should
             not breastfeed during this time.

        Exclusion Criteria:

          1. Past or current history of neoplasm other than the entry diagnosis, with the exception
             of treated non-melanoma skin cancer or carcinoma in situ of the cervix, or other
             cancers cured by local therapy alone, and a disease-free survival (DFS) >=3 years.

          2. Pregnancy or lactation. All females of child-bearing potential must have negative
             serum or urine pregnancy tests within 7 days prior to study treatment.

          3. Prior epithelial growth factor receptor (EGFR) inhibitors, with the exception of
             erlotinib, are not allowed. This includes both tyrosine kinase inhibitors (TKIs) and
             monoclonal antibodies. Prior vascular endothelial growth factor (VEGF) inhibitors,
             with the exception of bevacizumab, are not allowed.

         12. A serious underlying medical condition that would impair the ability of the patient to
