BAY 43-9006 (Sorafenib) to Treat Relapsed Non-Small Cell Lung Cancer

* 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.

Patients must have recovered from toxicity related to prior therapy to at least to grade 1 (defined by Common Terminology Criteria for Adverse Events (CTCAE) 3.0) and must not have had prior chemotherapy within 4 weeks. Patients must be at least 28 days since any prior radiation or major surgery.

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.

Eastern Cooperative Oncology Group (ECOG) performance status less than 2 (Karnofsky \> 60%).

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.
