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

Phase 2

Completed

Conditions: Non-Small-Cell Lung Carcinoma

Interventions: Drug: BAY 43-9006 (Sorafenib)

Registration Number: NCT00098254

Lead Sponsor: National Cancer Institute (NCI)

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.

Group	Intervention	Description
BAY 43-9006 (Sorafenib)	BAY 43-9006 (Sorafenib)	Self administered oral doses at 400 mg twice a day with 250 ml (8 oz.) of water each morning and evening (i.e., 12-hourly) continuously in a 28 day cycle. Tablets may be taken with or without food.

Primary Outcome Measures

Name	Time	Method
Response Rate	17 months	Percentage of participants with response rate = CR + PR. Response will be evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. CR (complete response) is the disappearance of all target lesions; PR (partial response) is a 30% decrease in the sum of the longest diameter of target lesions; PD (progressive disease) is a 20% increase in the sum of the longest diameter of target lesions; and SD (stable disease) are small changes that do not meet the above criteria. Please see the Protocol Link module for additional information about RECIST if desired.
Progression Free Survival	17 months	Time between the first day of treatment to the day of disease progression. Progressive disease is at least a 20% increase in the sum of the longest diameter of target lesions. Appearance of one or more new lesions and/or unequivocal progressions of existing non-target lesions.
The Number of Participants With Adverse Events	5 1/2 years	Here are the total number of participants with adverse events. For the detailed list of adverse events see the adverse event module.
