      Background:
      Clinical studies with anti-EGFR agents demonstrate that EGFR TKIs play critical roles in the treatment of non-small cell lung cancer, especially in patients with positive EGFR mutation. Icotinib is an oral, selective EGFR TKIs. Phase 3 study showed that icotinib is non-inferior to gefitinib in treating unselected or EGFR-mutated advanced NSCLC patients as second-line therapy but better safety profile, which provide a rationale to examine icotinib in first-line setting. The objective of this study is to evaluate progression-free survival (PFS), overall survival (OS) and safety of icotinib in chemotherapy naïve NSCLC patients with EGFR mutation.

      Methods:
      In this phase 3, open-label, randomized study (CONVINCE, NCT01719536), 285 patients (pathologically confirmed NSCLC, positive 19/21 EGFR mutation, treatment naive) will be 1:1 randomized to receive oral icotinib (125 mg, three times daily) or cisplatine (intravenous [IV], 75 mg/m2, day 1) plus pemetrexed (IV, 500 mg/m2, day 1), patients achieving disease control after 4-cycle chemotherapy continue to receive single pemetrexed (IV, 500 mg/m2, day 1) as maintenance therapy until progression. Randomization will be stratified by performance status (0-1/2), smoking status (smoker/non-smoker), disease stage (IIIB/IV), and mutation type (19/21). A total of 228 events would provide 90% power to detect an HR for PFS of 1 at 2-sided significance level of 0.05. Response will be reviewed by both investigator and independent data monitoring committee. Patient enrollment was completed in June 2014, and the results are expected in June, 2015.

      ORAL01.06 - S-1 and Cisplatin versus Docetaxel and Cisplatin in Patients with Untreated Advanced NSCLC: An Randomised, Multicenter, Phase 3 Trial (ID 2734)

      Background:
      Platinum-based doublet chemotherapy is the standard chemotherapeutic regimen for treatment-naïve advanced non-small cell lung cancer (NSCLC). S-1, an oral fluoropyrimidine, combined with carboplatin or cisplatin (CDDP) has demonstrated the non-inferiority to the standard platinum doublet chemotherapy in Japanese NSCLC patients. However, its effectiveness in Chinese NSCLC patients is uncertain. The purpose of this study is to compare the efficacy and safety of these chemotherapeutic regimens in Chinese NSCLC patients.

      Methods:
      We did this randomized controlled study in 21 sites in China. Eligible patients were those aged 18-70 years who was histologically or cytologically confirmed with locally advanced or metastatic NSCLC with no prior radiotherapy, molecular targeted therapy or chemotherapy. Patients were randomized to receive either S-1 orally 80 mg/m[2]/day (40 mg/m[2]2 b.i.d., 80–120 mg/day) with 60 mg/m[2] CDDP on day 8 every 5 weeks (SP) or docetaxel and CDDP (both 75 mg/m[2]) on day 1 every 3 weeks (DP) for up to 6 cycles. Randomisation was stratified by centre, pathological classification, disease stage and gender. The primary endpoint was progression free survival (PFS), analyzed in the full analysis set. The study is registered at ClinicalTrials.jp, number Japic CTI-111479.

      Results:
      Between March 2011 and November 2012, 246 patients from 21 institutions in China were randomly assigned and received SP or DP treatment (124 vs 122) with 18-month follow-up period from the last patient randomized. In the SP and DP group, median PFS was 5.9 and 5.7 months (HR=0.68; 95% CI, 0.48-0.96) respectively, median overall survival was 19.1 and 14.8 months, respectively (HR=0.84; 95% CI, 0.61-1.14). The most common grade 3 or worse adverse events in both treatment groups were neutropenia 3.3% vs 55.1%, leukopenia 1.7% vs 39.0%, and febrile neutropenia 0.8% vs 5.9%, of 121 patients in the SP group and of 118 patients in the DP group, respectively.

      Conclusion:
      The efficacy of SP was non-inferior to DP with a better safety profile. SP would be a new standard first-line chemotherapy regimen for Chinese patients with advanced NSCLC.
