Pharmacogenomic Study for Providing Personalized Strategy to the Treatment of Non-small Cell Lung Cancer (NSCLC) IIIB/IV

Overview

The primary objective of this randomized phase II study is to compare the Response Rate of each sequence of treatment approach in patients with advanced NSCLC. Additionally, development of gene expression profiles and genotypes that can predict response to commonly used chemotherapy may provide a unique opportunity to better utilize drugs shown to be effective in first- or second-line therapy. Here, the investigators will conduct a pharmacogenomic study to provide rational approach to the treatment of NSCLC by developing predictors of cisplatin (first-line agent) and pemetrexed or docetaxel (second-line agents) sensitivity and demonstrating the clinical value of identifying the most appropriate drug on the basis of sensitivity profile for the treatment regimen of each individual patient. Such an approach is likely to maximize response to chemotherapy and may change the current empirical paradigm of NSCLC therapy.

Cisplatin-based chemotherapy is currently considered to be the standard treatment in advanced non-small cell lung cancer (NSCLC). However, overall response is only 30-40%, suggesting that a majority of the patients do not respond to platinum. Subsequently, those patients who experience treatment failure with platinum-based therapy typically received pemetrexed or docetaxel as second-line treatment, with response rate of approximately 7% to 10%. The primary objective of this randomized phase II study is to compare the Response Rate of each sequence of treatment approach in patients with advanced NSCLC. Additionally, development of gene expression profiles and genotypes that can predict response to commonly used chemotherapy may provide a unique opportunity to better utilize drugs shown to be effective in first- or second-line therapy.
