Exclusion: Patients with any of the following will be excluded from participation in the study: Disease Squamous cell carcinoma, except for patients with no intrathoracic disease or small peripheral lesions only. Known central nervous system (CNS) metastases (Note: patients with brain metastases which have been controlled for ≥ 4 months without the use of steroid are eligible). Prior Treatments Less than 4 weeks between registration and the last receipt of chemotherapy, biotherapy, radiotherapy or major surgery Concurrent or planned hormonal agents such as replacement therapy, oral contraceptives, or anti-cancer therapy, e.g. Megace. (A prior history of such therapy is not exclusionary.) Administration of any investigational agent (therapeutic or diagnostic), including any investigational compound for the treatment of NSCLC, within 4 weeks prior to first study dosing Other Concomitant Medications High dose oral or intravenous corticosteroids. (Note: topical, inhaled and intra-articular corticosteroids are allowed. Prophylactic antihistamines are allowed before administration of bevacizumab Use of any medication which is a strong inhibitor or inducer of cytochrome P450 isoform CYP3A4 (see Appendix 5) Therapeutic dosing with warfarin >1 mg/day Chronic daily use of aspirin (> 325 mg/day) or other full-dose NSAIDs with anti-platelet activity Inability to take oral medication or requirement for IV alimentation or total parenteral nutrition with lipids, or prior surgical procedures affecting absorption Laboratory The following laboratory results, within 10 days of first study drug administration: Hemoglobin ≤ 9.0 g/dL Absolute neutrophil count ≤ 1.5 x 109/L Platelet count ≤ 100 x 109/L International Normalized Ratio (INR) > 1.3 (only if the subject is on warfarin [< 1 mg per day]) during 28 days prior to enrollment. aPTT > Upper Limit of Normal (ULN) during 28 days prior to enrollment. Serum creatinine ≥ 1.5 x ULN and creatinine clearance (by Cockcroft-Gault formula) <60 mL/min Serum bilirubin ≥ 1.5 x ULN Proteinuria: UPC ≥ 1.0 or ≥ 2+ proteinuria by urine dipstick, unless a 24-hour urine demonstrates <1.0 g/24 hours ALT or AST ≥ 2.5 x ULN (≥ 5 x ULN if liver metastases) Alkaline phosphatase ≥ 2.5 x ULN Albumin ≤ 2.5 g/L Women of child bearing potential: positive pregnancy test (serum). Other Conditions or Procedures Any clinically significant adverse events from any prior chemotherapy, surgery or radiotherapy which has not yet resolved to CTCAE v3.0 grade ≤ 1 Known hypersensitivity to any oligodeoxynucleotide (ODN), EGFR-inhibitor or bevacizumab Serious, non-healing wound, ulcer or bone fracture Patients with a history or current neoplasm other than the entry diagnosis, except for curatively treated non-melanoma skin cancer or carcinoma in situ of the cervix and except for other cancers treated for cure and with a disease-free survival greater than 5 years. Pregnant or breast-feeding women Men or women of childbearing potential who refuse or who are unable to use an acceptable means of contraception History of clinically significant hemoptysis within 3 months prior to registration unless definitively treated with surgery or radiation Any medical conditions that would impose excessive risk to the patient, such as uncontrolled hypertension (systolic >150 mmHg or diastolic >100 mmHg per JNC 7 guidelines, congestive heart failure NYHA Class 2-4, uncontrolled or unstable angina, myocardial infarction within the previous 6 months, ventricular arrhythmia, infection requiring parental or oral anti-infective treatment, any altered mental status or any psychiatric condition that would interfere with understanding the informed consent, uncontrolled seizures, chronic hepatitis or cirrhosis, known human immunodeficiency virus (HIV) infection, known hepatitis B surface antigen (HBsAg) positive or uncontrolled diabetes. (Note: testing for HIV infection of HBsAg is not part of the screening assessments performed by the central laboratory). Pre-existing autoimmune or antibody-mediated diseases, including, but not limited to, the following: systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, Sjogren's syndrome and autoimmune thrombocytopenia Evidence of bleeding diathesis or coagulopathy or other serious or acute internal bleeding within 6 months prior to registration CNS bleeding; history or clinical evidence of CNS stroke (hemorrhagic or thrombotic) within the last 6 months History of allogeneic organ transplant Brain biopsy within 12 weeks of first study dosing Minor surgical procedure, central venous catheter placement, fine needle aspirations or core biopsy within 7 days prior to first study dosing Anticipation of need for a major surgical procedure during the course of the study Other Unwilling or unable to comply with the protocol for the duration of the study
