This multi-centered phase II trial will examine pazopanib stage IIIB/IV non-squamous NSCLC patients who have progressed on first-line therapy containing bevacizumab. Treatment should continue until disease progression, unacceptable toxicity, study withdrawal, or death. Patients who progress will be treated at the discretion of their physician. all patients who initiate treatment will be evaluated for disease control rate, which is the primary endpoint of this study.
The primary objective is to estimate the disease control rate of pazopanib alone in patients with stage IIIB/IV non-squamous NSCLC who progressed while on bevacizumab. Disease control rate id defined as complete (CR) + partial response (PR) + stable disease (SD) lasting greater than or equal to 12 weeks as defined by RECIST.
Secondary Objectives To estimate the combined response rate (CR + PR) of pazopanib according to RECIST To estimate the progression free survival (defined as time of enrollment until disease progression or death) and overall survival (defined as time of enrollment until death) of patients treated with pazopanib.
To evaluate the safety and tolerability of pazopanib using the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) version 4.0 To explore potential correlations between blood biomarkers and clinical response.
Pazopanib is dosed continuously throughout the study. Cycle lengths are identified as 21 days for purposes of the calendar.
The treatment dosage and administration for participating subjects will be, Pazopanib, 800 mg by mouth daily during a 21 day cycle until disease progression.
