Subject must be willing to comply with treatment and follow-up. * Subjects ≥21 years of age with a life expectancy of ≥12 weeks * The time between initial diagnosis and the scheduled surgery date allows for the subject to receive a minimum of 2 weeks or a maximum of 6 weeks treatment with pazopanib. Note: At least 4 weeks must be available between the diagnostic biopsy and surgery to allow for 1) one-week delay following the diagnostic biopsy prior to first dose of study drug, 2) minimum of 2 weeks on study drug, and 3) minimum of 1 week wash out prior to surgery. * Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1. * Histologically- or cytologically-confirmed Stage IA, IB, IIA, or IIB (to T2) NSCLC according to the International Staging System \[Mountain, 1997\] and must be scheduled for surgical resection. * Disease must consist of only a single lesion and must be measurable according to high-resolution CT scan-assisted volumetric measurement \[Yankelevitz, 2000, Armato, 2004\].

MeasureTime frameDescription
Number of Participants Achieving Tumor Shrinkage Based on Change in Tumor VolumeBaseline to at least two weeks or at most six weeksTumor shrinkage was assessed as the change in tumor volume using high-resolution computed tomography scans of the thorax following treatment with pazopanib. Response is defined as the number of participants achieving at least 50% tumor volume reduction following pazopanib treatment. Responder is a participant whose tumor volume reduced at least 50% following pazopanib treatment. Non-responder is a participant whose tumor volume did not reduce at least 50% following treatment. Tumor assessments were conducted by a central reviewer.

Number of Participants Achieving a >=60% Reduction in Tumor Metabolic Activity Determined as Standard Uptake Value (SUV)Baseline to at least two weeks or at most six weeksResponse is the number of participants whose tumor demonstrated a 60% or greater reduction in metabolic activity (SUV) as measured by positron emission tomography (PET) or PET/computed tomography (PET/CT) at the end of treatment visit relative to baseline. This analysis was not conducted because insufficient data were collected: only three participants had PET/CT data.

Baseline blood pressure values as well as the change from baseline experienced are given in the category titles.
Number of Cells Exhibiting Apoptosis in Participant SamplesBaseline to at least three weeks and at most 8 weeks (surgery date)Tumor cells from pre-treatment and post-operative biopsies were to have been analyzed to determine the number of cells that were exhibiting apoptosis. Due to the limited quantity of tissue in pre- and post-treatment biopsy samples, these assays were not performed.
Ratio of Post- to Pretreatment Expression Levels for Each of the Indicated Pazopanib Target GenesBaseline to at least three weeks and at most 8 weeks (surgery date)Gene expression data analysis was performed with GeneSpring GX 7.3.1 (Agilent Technologies). Data were preprocessed using the RMA algorithm. The Benjamini and Hochberg false discovery rate was used for multiple testing corrections. Data below are log-transformed ratios of the post-treatment to pre-treatment expression intensity, indicating the fold increase/decrease in expression of genes. PDGF, platelet-derived growth factor; VEGFR, vascular endothelial growth factor receptor; c-KIT, a protein tyrosine kinase that is a receptor for stem cell factor or kit ligand.
Number of Participants Achieving a Clinical Response Based on RECISTBaseline to at least two weeks or at most six weeksResponse is the number of participants achieving either complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR, all detectable tumor has disappeared; PR, a \>=30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum; Progressive disease (PD), a \>=20% increase in target lesions; Stable Disease, small changes not meeting previously given criteria. Confirmation requires at least 2 assessments (conducted by a central reviewer) of CR/PR with at least 4 weeks between the assessments.
Intratumoral Levels of Specific BiomarkersBaseline tumor biopsyA pre-treatment tumor biopsy from each participant was to have been analyzed by Western blotting to semi-quantitate levels of various proteins related to angiogenesis and/or to the mechanism of action of pazopanib. These assays were not carried out due to insufficient quantity of tissue present in the pre-treatment biopsy (fine needle aspirate). The clinical study report indicates that results were to have been reported separately.
Plasma Levels of Lactate Dehydrogenase-5 (LDH5)Baseline to at least three weeks and at most 8 weeksLDH5 has been shown to be associated with activation of angiogenesis in lung cancer. Circulating levels of LDH5 were to have been measured at each scheduled visit through the post-treatment visit to determine if a correlation with drug effect existed. Levels of LDH5 were measured, but the team determined that greater value was to be derived from transcriptional and plasma biomarker analyses; thus, no analyses were conducted to examine the correlation of LDH5 levels with effects of pazopanib.
Genetic Variations in Germline DNABaselinePlasma samples were collected from each consenting participant, generally at baseline, to permit evaluation of the presence or absence of genetic variations in select candidate genes in germline DNA. Analyses that could have been done might have examined the relationship between genetic variants and the safety or tolerability or the efficacy of pazopanib. Analyses have not yet been conducted, but a need to do so may yet be identified. The clinical study report indicated that results, if any, would be reported separately.
Semiquantitative Levels of Staining in Pre-treatment Tumor Biopsies (e.g. VEGF, VEGFR-1,VEGFR-2).Entire study intervalAnalysis not performed as part of study. Appropriate material was not available for analysis.
Ratio of Post- to Pretreatment Expression Levels for Each of the Indicated Pazopanib Target ProteinsBaseline to at least two weeks and at most 6 weeksBaseline and post-therapy plasma samples were obtained from participants. Immunohistochemistry analyses were carried out using a BioPlex 200 machine (Bio-Rad) or by enzyme-linked immunoassays to evaluate levels of angiogenesis-related proteins and other relevant proteins. Post- and pre-treatment changes in cytokines and angiogenic factors in response to pazopanib were analyzed. A negative value indicates that the post-treatment level of the particular target protein was less than the pre-treatment level.
Gene Mutations in Pre- or Post-treatment Tumor BiopsiesBaseline to at least three weeks and at most 8 weeks (surgery date)Specific genes (KRAS, MYC, TP53, and others) were to have been analyzed for the presence or absence of amplifications or deletions and for the presence, absence, and sequence of point mutations in pre- or post-treatment tumor biopsies. These analyses were not conducted because the potential results were considered to provide overlapping information with those obtained in the transcriptional and proteomic profiling assays that were conducted. The clinical study report indicates that genetic measures were to have been reported separately.
