Further study details as provided by Samsung Medical Center:

Primary Outcome Measures:
  • predictive value of TS expression [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    To determine the predictive value of thymidylate synthase expression in NSCLC patients treated with pemetrexed combination therapy by interaction P value

Secondary Outcome Measures:
  • response rate [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Whether the response rate of CG regimen is higher than that of CP regimen in TS+ patients

  • response rate [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Whether the response rate of CP regimen is higher than that of CG regimen in TS- patients

Estimated Enrollment: 304
Study Start Date: July 2011
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
