Sunitinib Malate as Maintenance Therapy in Treating Patients With Stage III or Stage IV Non-Small Cell Lung Cancer Previously Treated With Combination Chemotherapy

This randomized phase III trial studies sunitinib malate to see how well it works when given as maintenance therapy (meaning it is approved for treatment after chemotherapy) in patients with stage IIIB-IV non-small cell lung cancer who have responded to prior treatment with combination chemotherapy. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking the growth of new blood vessels necessary for tumor growth. It is not yet known whether sunitinib malate is effective in helping tumors continue to shrink or stop growing.

PRIMARY OBJECTIVES:

I. To evaluate the effect of sunitinib (sunitinib malate) compared to placebo on progression-free survival (PFS) in advanced non-small cell lung cancer (NSCLC) patients who have had either stable or responding disease over the course of their initial 4 cycles of platinum-based therapy.

SECONDARY OBJECTIVES:

I. To evaluate the toxicity of sunitinib compared to placebo in the maintenance setting.

II. To evaluate the additional response rate as a result of sunitinib in this setting.

III. To assess the impact of sunitinib on overall survival compared to the placebo arm.

IV. To assess the impact of sunitinib on delaying the time to deterioration in quality of life and symptom progression compared to placebo using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and Lung Cancer Module (LC13).

V. To assess vascular endothelial growth factor (VEGF) haplotypes in advanced non-small cell lung cancer and sunitinib maintenance.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive sunitinib malate orally (PO) once daily (QD) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive placebo PO QD on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 1 year, and then periodically for 3 years.

  * Measurable disease: lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as \>= 2 cm with conventional techniques or as \>= 1 cm with spiral computed tomography (CT) scan
  * Non-measurable disease: all other lesions, including small lesions (longest diameter \< 20 mm with conventional techniques or \< 10 mm with spiral CT scan) and truly non-measurable lesions; lesions that are considered non-measurable include the following:

    * Bone lesions
    * Leptomeningeal disease
    * Ascites
    * Pleural/pericardial effusion

    * Cystic lesions
* Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
* Non-pregnant and non-nursing
* No ongoing cardiac dysrhythmias, atrial fibrillation, or history of corrected QT (QTc) interval \>= 500 msec (within 2 years prior to registration); the use of agents with proarrhythmic potential (e.g., quinidine, procainamide, disopyramide, sotalol, probucol, haloperidol, risperidone, indapamide, flecainide) is not recommended while on protocol therapy
* Patients with class I New York Heart Association (NYHA) heart failure are eligible; patients with a history of class II NYHA heart failure are eligible, provided they meet at least one of the following criteria:

  * Patients with a history of class II heart failure who are asymptomatic on treatment
  * Patients with prior anthracycline exposure
  * Patients who have received central thoracic radiation that included the heart in the radiotherapy port
* Patients with a history of class III or IV NYHA heart failure within 12 months prior to registration are not eligible
* No myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft or stenting, cerebrovascular accident or transient ischemic attack within the last year
* Patients with hypertension that cannot be controlled by medications (\> 150/100 mmHg despite optimal medical therapy) are not eligible
* Patients who require use of therapeutic anticoagulation for thromboembolic disease are not eligible; Note: low doses of coumadin (up to 2 mg daily) are permitted for prophylaxis of thrombosis
* No history of venous thrombosis, pulmonary embolism, or hypercoagulopathy syndrome
* No history of pulmonary hemorrhage, bleeding diathesis, or evidence of hemoptysis; patients with blood-tinged or blood-streaked sputum will be permitted on study if the hemoptysis amounts to less than 5 ml of blood per episode and less than 10 ml of blood per 24-hour period in the best estimate of the investigator
