Clinical Trial of the Safety and Effectiveness of CHR-2797 With Erlotinib in Patients With Locally Advanced or Metastatic Non-small Cell Lung Cancer

You may not be if

• 2. NSCLC with documentation of Stage IIIB (with pleural effusion), or Stage IV, or recurrent metastatic disease based on current TNM classification
• 3. Disease progression or relapse following failure of platinum-based chemotherapy
• 4. For Study Phase A, patients are not required to have measurable disease (according to RECIST criteria) for enrollment. For patients in Study Phase B, patients must have measurable disease according to RECIST, defined by at least 1 lesion that can be accurately measured. All other lesions (e.g., pleural effusions) including small lesions (\<1 cm×1 cm by spiral CT scan) are considered non-measurable for the purposes of this study. Baseline tumor measurements are to be completed as close as possible to, but no longer than 14 days before the start of study treatment
• 5. Prior radiation to the measurable site(s) of disease is not allowed, unless disease progression has been documented at that site since the radiotherapy. Patients who have had extensive radiotherapy are also excluded, because of the associated myelosuppressive effect
• 6. Prior surgery is allowed, provided it was completed at least 4 weeks prior to enrollment and the patient has recovered from surgery.
• 7. No known prior primary brain, metastatic brain, or meningeal tumors or clinical signs or symptoms of brain metastases
• 8. Able to understand and willing to sign an informed consent document
• 9. Age ≥18 years
• 10. Predicted life expectancy \>3 months
• 11. Eastern Cooperative Oncology Group (ECOG) performance status score ≤2
• 12. Laboratory values within the normal or reasonable ranges and, specifically,adequate bone marrow, hepatic, and renal function including the following:
• * Hemoglobin \>10 g/dL, absolute neutrophil count (ANC)\>1.5×109/L, platelets ≥100×109/L
• * Total bilirubin ≤1.5× upper limit normal (ULN)
• * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \<2.5×ULN or \<5×ULN in patients with documented liver metastases
• * Creatinine ≤1.5×ULN or calculated creatinine clearance ≥60 mL/min
• 13. Female patients with reproductive potential must have a negative serum pregnancy test within 72 hours prior to start of study medication. All female patients of childbearing potential, and all male patients, must agree to use a medically acceptable method of contraception or agree to be abstinent throughout the treatment period and for 3 months after discontinuation of treatment. (See Section 4.1for more information.)
• 14. Screening for LVEF \>= 55%
• 1. Excluded therapies:
• * Concurrent anti-cancer therapy
• * Treatment with cytotoxic agents within the last 3 or 4 weeks, depending on the usual frequency of administration of the regimen, or within the last 6 weeks for agents such as mitomycin. Patients must have had resolution of acute treatment-related toxicities to baseline or National Cancer Institute Common Toxicity Criteria (NCI-CTC) Grade \<1, with the exception of alopecia
• * Therapy within the last 28 days or while on study with another investigational drug
• * Use of biological response modifiers, such as granulocyte-colony stimulating factor (G-CSF) or erythropoietin, within 28 days of enrollment
• * Prior therapy with an epidermal growth factor receptor (EGFR) inhibitor
• * Radiation to the site(s) of measurable disease, unless disease progression has been documented at that site since the radiotherapy.
• * Need for palliative radiotherapy of indicator lesions
• * Treatment with known strong CYP3A4 inhibitors, for example '- azole antifungals, protease inhibitors, erythromycin, clarithromycin within 2 weeks of enrollment or at any time during the study
• * Treatment with strong CYP3A4 inducers such as rifampicin, rifabutin or rifapentine within 2 weeks of enrollment or at any time during the study
• * Warfarin or doses of coumadin (or equivalent) that are higher than 1mg/day
• 2. Excluded medical conditions:
• * Current hematological malignancy
• * Gastro-intestinal abnormalities including:
• * Inability to take oral medication
• * Requirement for intravenous (IV) alimentation
• * Malabsorption syndrome
• * Active peptic ulcer disease
• * A serious uncontrolled medical disorder or active infection which would impair their ability to receive study treatment
• * Known primary brain, metastatic brain, or meningeal tumors, or clinical signs or symptoms of brain metastases
• * Second malignancy (except adequately treated basal cell carcinoma of the skin or in-situ carcinoma of the cervix or breast)
• * Known history of human immunodeficiency virus (HIV) infection or chronic hepatitis B or C
• * Uncontrolled hypercalcemia (\>NCI-CTC Grade 1)
• * Significant cardiovascular disease including but not limited to the following:
• * History (past or present) of congestive heart failure
• * History (past or present) of angina pectoris requiring medication
• * History of myocardial infarction with past 12 months
• * Presence of clinically significant valvular heart disease
• * History (past or present) of arrhythmia requiring treatment
• * Presence of conduction defect on Screening ECG
• * History (past or present) of uncontrolled hypertension
• * Patients with interstitial lung disease
• 3. Major surgery within 4 weeks prior to enrollment
• 4. \>20% weight loss in previous 3 months
• 5. Pregnant or lactating women
• 6. Known rapidly deteriorating liver function tests (2×ULN rise in 1 week)
• 7. Dementia or significantly altered mental status that would prohibit the understanding or rendering of informed consent and/or compliance with the requirements of the protocol
• 8. Known or suspected allergy to any study medication used in this study
