Brief summary: RATIONALE: Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. It is not yet known whether pazopanib hydrochloride is more effective than a placebo in treating patients with non-small cell lung cancer that has not progressed after first-line chemotherapy.

PURPOSE: This randomized phase II/III trial is studying how well giving pazopanib hydrochloride works and compares it with giving a placebo in treating patients with non-small cell lung cancer who have received first-line chemotherapy.

Detailed description: OBJECTIVES:

Primary

* To compare the therapeutic benefit, in terms of overall survival, of maintenance pazopanib hydrochloride in patients with non-small cell lung cancer who have not progressed after first-line chemotherapy.

Secondary

* To compare progression-free survival (PFS) overall and at specific time points (6 and 12 months).
* To document the toxicity profile of pazopanib hydrochloride according to the CTCAE v 4.
* To assess the use of C-reactive protein (CRP) in the detection of progression of disease in the maintenance phase of therapy.
* To compare quality-of-life of patients on maintenance therapy.
* To compare discontinuation rate/treatment compliance of patients treated with these regimens.
* To collect health economics data on resource utilization as documented by the EQ-5D generic QoL instrument.

Tertiary (correlative)

* To evaluate the effect of germline genetic variations on drug response (pharmacogenetics) using PAX gene.
* To find relevant biomarkers of VEGFR pathways from plasma samples.
* To obtain the pharmacokinetics of pazopanib hydrochloride at 600 and 800 mg.
* To evaluate biomarkers in tumor tissue.

OUTLINE: This is a multicenter, randomized study. Patients are stratified according to center, histology (squamous vs nonsquamous), performance status (0-1 vs 2 up to 15% of patients), and response to initial chemotherapy (complete response/partial response vs stable disease). Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive an oral placebo daily on days 1-28. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
* Arm II: Patients receive oral pazopanib hydrochloride daily on days 1-28. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.

Patients complete quality-of life-questionnaires (QLQ-C30 and QLQ-LC13) at baseline, 6 weeks, 14 weeks, and 22 weeks.

Health economics data on resource utilization are collected and documented using the EQ-5D questionnaire.

Blood samples may be collected periodically for pharmacokinetics and pharmacogenetic studies. Samples are analyzed for germline genetic variations on drug response, relevant biomarkers of VEGFR pathways, and concentration of pazopanib hydrochloride. Previously collected tumor tissue is analyzed for biomarkers.

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

Eligibility criteria: DISEASE CHARACTERISTICS:

* Histologically or cytologically confirmed non-small cell lung cancer (NSCLC) meeting the following criteria:

  * Any histology
  * Stage IIIB-IV disease
* Newly diagnosed or recurrent disease (after surgery or radical radiotherapy) proven on cytology or histology before induction chemotherapy

  * In case of adjuvant chemotherapy after previous surgery, time interval from start of previous treatment to induction chemotherapy for metastatic disease is 12 months
* May or may not have measurable disease as defined by RECIST criteria
* Must not have progressed during the 4 courses of initial chemotherapy

  * For patient presenting with measurable disease, there must be documented radiographic evidence of response (complete response, partial response, or stable disease) according to RECIST 1.1 criteria
  * For patients without measurable disease, there must be no symptomatic/clinical progression
* EGFR wild-type or unknown (known EGFR mutations are not eligible)
* Brain metastases allowed provided they are controlled and the patient must present with a performance status (PS) of 0-1 after the 4 courses of chemotherapy and at least 1 week off steroids
* No known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage, including any of the following:

  * Large protruding endobronchial lesions in the main or lobar bronchi

    * Endobronchial lesions in the segmented bronchi are allowed
  * Lesions extensively infiltrating the main or lobar bronchi

    * Minor infiltrations in the wall of the bronchi are allowed
  * Lesions infiltrating major pulmonary vessels (contiguous tumor and vessels)

    * Tumors touching but not infiltrating (abutting) the vessels are acceptable
