Summary

In this trial, treatment efficacy and safety of retreatment with 1st generation epidermal growth factor receptor(EGFR) tyrosine kinase inhibitor(TKI)s(Gefitinib/Erlotinib), will be assessed in patients with sensitizing EGFR mutation positive Non-Squamous Cell Carcinoma patients who previously treated with EGFR TKI and cytotoxic chemotherapy

Description

This study is designed to be multi-center, open-label, single-arm, prospective, phase II trial of patient with sensitizing EGFR mutation positive Non-Squamous Cell Carcinoma patients who previously treated with EGFR TKI and cytotoxic chemotherapy. Approximately 69 patients will be enrolled into the trial, and expected study duration is 48 months from Institutional Review Board(IRB) and Korea Ministry of Food and Drug Safety(MFDS) approval date.

The study drug will be administered orally as one tablet(Gefitinib 250mg/ Erlotinib 150mg) once a day until disease progression or manifestation of unacceptable toxicity. The initial dose of the study drug daily can be reduced according to dose reduction criteria in protocol. A cycle of study treatment is defined as 28 days, and subjects will visit the site every 2 cycles(56 days).
