Biomarkers Predicting Response in Patients With Non-Small Cell Lung Cancer Previously Treated With Erlotinib Hydrochloride
Recruitment status was Not yet recruiting
RATIONALE: Studying samples of blood in the laboratory from patients receiving erlotinib hydrochloride may help doctors learn more about the effects of erlotinib hydrochloride on cells. It may also help doctors understand how well patients respond to treatment.
PURPOSE: This research study is studying biomarkers predicting response in patients with non-small cell lung cancer previously treated with erlotinib hydrochloride.
Other: enzyme-linked immunosorbent assay
Other: laboratory biomarker analysis
|Official Title:||Measurement of Potential Biomarkers Predicting Erlotinib Response|
- Baseline serum NGAL, MMP-9, NGAL/MMP-9 complex, and soluble E-cadherin levels as predictors of erlotinib hydrochloride response [ Designated as safety issue: No ]
|Study Start Date:||April 2010|
|Estimated Primary Completion Date:||April 2011 (Final data collection date for primary outcome measure)|
- To evaluate whether serum NGAL, MMP-9, NGAL/MMP-9 complex, and soluble E-cadherin can be utilized as biomarkers to predict response in patients with non-small cell lung cancer treated with erlotinib hydrochloride.
OUTLINE: Serum samples are analyzed for NGAL, MMP-9, NGAL/MMP-9, and soluble E-cadherin by ELISA and Luminex assays.
