Brief Summary:
The purpose of this study is to evaluate how participants with advanced non-small cell lung cancer (NSCLC) that have certain abnormalities in the pazopanib target genes respond to pazopanib treatment.

Condition or disease Intervention/treatment Phase
Carcinoma, Non-Small Cell Lung Non-Small Cell Lung Cancer Nonsmall Cell Lung Cancer Drug: Pazopanib Phase 2

Detailed Description:
There has been a limited benefit from anti-angiogenesis drugs in patients with NSCLC. Bevacizumab provides a modest survival improvement when added to chemotherapy and VEGFR tyrosine kinase inhibitors have been associated with minimal efficacy as single agents and increased toxicity when combined with chemotherapy. We postulate that the response rates and survival may be improved with a better selection of patients based on abnormalities of the targets for the drugs. According to the preliminary data from the cancer genome atlas (TCGA), the targets of pazopanib are altered in 28% of patients with adenocarcinoma and 24% of patients with squamous cell lung cancer. Since, despite the molecular selection prior to treatment, only a small percentage of patients will benefit from the treatment, we plan to further investigate those patients with whole exome sequencing in both the pre-treatment samples to identify the predictors for response and at the time of progression, with repeated biopsy, in an attempt to identify the predictors for secondary resistance. By identifying more reliable predictors for response to pazopanib, our study may help to establish its role in the treatment of NSCLC.

Drug Information available for: Pazopanib

Arm Intervention/treatment
Experimental: Treatment: Pazopanib

Pazopanib 800 mg daily should be taken orally without food at least one hour before or two hours after a meal.

One cycle of pazopanib is 28 days.

Drug: Pazopanib
Other Names:
  • GW786034
  • Votrient®

Primary Outcome Measures :
  1. Response Rate [ Time Frame: Until the end of treatment (median length of treatment=85.5 days (full range 25-334 days) ]
    • Participants should be re-evaluated for response 8 weeks after initiation of pazopanib and then every 8 weeks thereafter. In addition to a baseline scan, confirmatory scans should also be obtained not less than 4 weeks following initial documentation of objective response.
    • Response and progression will be evaluated in this study using the new international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) [Eur J Ca 45:228-247, 2009].
    • Response rate is the percentage of participants with a complete or partial response
    • Complete response=Disappearance of all target and non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis).
    • Partial response=At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters

  2. Progression-free Survival (PFS) [ Time Frame: Until progressive disease or death (median follow-up 174 days, full range 41 days-545 days) ]
    • Progression-free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. There is no limit on following for progression-free survival besides death of the participant.
    • Progressive disease=At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).

Secondary Outcome Measures :
  1. Outcomes Associated With Specific Mutations [ Time Frame: Until time of death (an expected average of 8 months) ]
    • Participants are followed until death.
    • All participants will undergo next generation sequencing prior to enrollment into the study.
    • Initial predictors are the mutations in VEGFR or PDGFR, but sequencing will be used to evaluate for other predictors as well.

  2. Mutational Predictors for Extreme Responders [ Time Frame: Until end of treatment (an expected average of 8 months) ]
    -Whole exome and transcriptome sequencing will be performed in 10 participants, including 4 to 6 responders and 4 to 6 non-responders in order to identify the predictors for benefit.

  3. Mechanisms of Secondary Resistance. [ Time Frame: Until the time of progressive disease (an expected average of 8 months) ]
    -Participants will also undergo next generation sequencing at the time of progression in an attempt to identify the mechanisms for secondary resistance.
