Brief summary: This study will investigate the effects and side effects of BAY 43-9006 in patients with advanced, recurrent, or refractory non-small cell lung cancer (NSCLC). BAY 43-9006 is one of a new class of anticancer agents known as bi-aryl ureas.

Patients 18 years of age and older with NSCLC that has recurred or progressed after one regimen of chemotherapy may be eligible for this study. Candidates are screened with a medical history and physical examination; blood tests; tumor biopsy (see below); chest x-ray; electrocardiogram; and imaging studies, including positron emission tomography-computed tomography (PET-CT, see below) and dynamic, contrast-enhanced MRI (DCE-MRI, see below).

Participants take BAY 43-9006 by mouth twice a day, morning and evening. On the first and 15th days of treatment, patients are admitted to the hospital for pharmacokinetic studies; that is, a test of how the body handles the drug. For the test, blood is collected at intervals (at 15 minutes, 30 minutes, and 1, 2, 4, 6, 8, 12 and 24 hours after ingestion) to determine the drug's level in the bloodstream. Treatment with BAY 43-9006 continues until the study doctor determines that the medication is not beneficial or the patient wishes to withdraw from the study.

In addition to drug therapy, patients undergo the following tests and procedures:

* Physical examination every 4 weeks
* Blood pressure checks once a week during the first 4 weeks
* Blood tests every week
* CT scans or other imaging tests, such as ultrasound or MRI, every 8 weeks to evaluate the tumor's response to treatment. CT is an x-ray test that provides detailed pictures of the inside of the body. It can be done from different angles, providing a 3-dimensional picture of the part of the body being studied and allowing the doctor to see the location, nature, and extent of disease. MRI uses a powerful magnet and radio waves instead of x-rays to produce accurate, detailed pictures of organs and tissues.
* PET-CT approximately every 8 weeks to look at how different parts of the body take up and use glucose (a sugar nutrient). Because rapidly growing cells, such as tumors, use more sugar than normal cells do, this test can be used to detect cancer. For the test, the patient is given an injection of a sugar solution in which a radioactive tracer has been attached to the sugar molecule. A special camera detects the radiation emitted by the solution, and the resulting images show how much sugar is being used in various parts of the body. PET-CT uses the PET scan in combination with standard CT in a machine that does both tests.
* DCE-MRI after 2 weeks of treatment. This test uses MRI with a special non-radioactive dye to examine blood flow in a certain part of the body.
* Tumor biopsy (optional) after 2 weeks of treatment. A biopsy is the surgical removal of a small piece of tissue. The tumor biopsy is done either using a small bore needle under CT guidance or by direct visualization using a laparoscope/thoracoscope. For the needle biopsy, a needle is inserted through the skin and guided by CT into the tumor mass. For the laparoscopy/thoracoscopy, the patient is sedated or asleep and small lighted tubes are inserted into small holes made in the skin. The tumor is located and tissue withdrawn.

Detailed description: Despite advances in systemic chemotherapy, patients with stage IV NSCLC will die from their disease. The median survival of all patients is 8-16 months, with a one year-survival rate of 33%. Chemotherapy is the mainstay of treatment of advanced disease. Based on available data from randomized trials, current treatment recommendations are to treat with one of several effective cisplatin-doublets which have resulted in median survival of 16 to 18 months. Second line chemotherapy is able to improve outcome in patients who have had prior cisplatin therapy. Although these important milestones represent improvements in the care of patients with metastatic NSCLC, outcome has not been able to be further improved by substituting one active drug for another in a platinum-based doublet, treating patients with more than four cycles of chemotherapy or by using cisplatin-based triplets. It is clear that if we are to improve outcome of NSCLC patients, we will need to develop drugs with novel mechanisms of action that perhaps will inhibit major cellular signaling pathways affecting survival, proliferation and angiogenesis. One new compound, BAY 43-9006, was designed to inhibit Raf and is also known to inhibit other kinases including VEGFR2, VEGFR3, PDGFR-beta, Flt3, c-KIT, and p38(1). BAY 43-9006 has shown in vitro activity against NSCLC cell lines NCI-H460 and A549 with tumor growth inhibition of 27% to 68%. In addition, BAY 43-9006 has shown activity in the H460 NSCLC xenograft model. In NSCLC, the proliferation signaling of the Ras/Raf/MEK/ERK pathway is increased due to the frequent (30%) presence of K-ras mutations in the tumor. Mutations in K-ras have been associated with malignant transformation of normal epithelium and constitutive activation of p21 and its downstream effects on cellular proliferation and inhibition of apoptosis. Clinical observations have shown that tumors with K-ras mutations tended to be smaller but more poorly differentiated, and associated with a significantly worse three-year mortality rate. As mentioned above, other pathways significant to the malignant potential of NSCLC, particularly those involved in angiogenesis, may also be affected by BAY 43-9006. The in vitro and in vivo data support the clinical investigation of BAY 43-9006 as an inhibitor of the Ras/Raf/MEK/ERK downstream proliferation effects. The goal of this phase II trial is to determinate if BAY 43-9006 is active in NSCLC, and to measure the BAY 43-9006 biological effects on the Ras/Raf/MEK/ERK pathway. To achieve these goals, patients with relapsed or recurrent NSCLC will be given BAY 43-9006 (four weeks cycle of 400mg PO BID). A series of correlative studies will be done during treatment to measure biological and clinical effects of BAY 43-9006. These studies will include analyses of tissue and blood samples as well as correlative imaging studies.

Eligibility criteria: * INCLUSION CRITERIA:

Histologically documented Non-small cell lung cancer and confirmed by the Laboratory of Pathology at the Clinical Center/National Institutes of Health (NIH) or the Laboratory of Pathology at National Naval Medical Center (NNMC).

Recurrent or progressed Non-Small Cell Lung Cancer (NSCLC).

Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as greater than 20 mm with conventional techniques or as greater than 10 mm with spiral Computed tomography (CT) scan.

Age greater than 18 years (males or non-pregnant females). Because no dosing or adverse event data are currently available on the use of BAY 43-9006 in patients less than 18 years of age, children are excluded from this study but will be eligible for future pediatric single-agent trials, if applicable.

Life expectancy of greater than 3 months.

Patients must have adequate organ and marrow function (as defined below). Patients must have returned to base line or grade one from any acute toxicity related to prior therapy.

Leukocytes greater than 3,000/micro l;

Absolute neutrophil count greater than 1,200/micro l;

Platelets greater than 100,000/micro l;

International normalized ratio (INR) less than or equal to 1.2

Partial thromboplastin time (PTT) less than or equal to 36 seconds or abnormality can be explained by the presences of lupus anticoagulant

Total bilirubin less than or equal to 1.5 times the institutional upper limits of normal;

Aspartate aminotransferase, oxaloacetic transaminase (AST,SGOT) and alanine transaminase, serum glutamic pyruvic transaminase (ALT,SGPT) less than 2.5 times the institutional upper limits of normal;

Creatinine or creatinine clearance less than or equal to 1.5 times the institutional upper limits of normal or greater than 45 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal.

The effects of BAY 43-9006 on the developing human fetus at the recommended therapeutic dose are unknown. For this reason and because kinase inhibitors are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and continue for at least 2 months after completion. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with BAY 43-9006, breastfeeding should be discontinued if the mother is treated with BAY 43-9006.

Ability to comply with daily oral self administration schedule, and the ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

Patients with symptomatic brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. However, patients who have had treatment for their brain metastases and whose brain metastatic disease status has remained stable for at least 3 months without steroids may be enrolled at the discretion of the principal investigator.

Uncontrolled medical illness including, but not limited to, ongoing or uncontrolled, symptomatic congestive heart failure (American Heart Association (AHA) Class II or worse), uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Human immunodeficiency virus (HIV)positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with BAY 43-9006. HIV positive patients not receiving antiretroviral therapy are excluded due to the possibility that BAY 43-9006 may worsen their condition and the likelihood that the underlying condition may obscure the attribution of adverse events with respect to BAY 43-9006.

Patients may not be receiving any other investigational agents.

History of another invasive malignancy in the last five years. Non-invasive, non-melanoma skin cancers will be allowed.

Patients with conditions that would impair their ability to swallow tablets are excluded.

Patients must not have any evidence of bleeding diathesis.

Patients must not be on therapeutic anticoagulation. Prophylactic anticoagulation (i.e. low dose warfarin) of venous or arterial access devices is allowed provided that the requirements for prothrombin time (PT), international normalized ratio (INR) or partial thromboplastin time (PTT) are met.

Both men and women and members of all races and ethnic groups are eligible for this trial. Every effort will be made to recruit women and minorities in this study.
