Clinical Trial Summary

This is an open-label, multicenter, randomized, phase II clinical trial, which aims to evaluate the effectiveness and safety of gefitinib versus combination of gefitinib and doublet chemotherapy or apatinib in advanced non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) activating mutation (exon 19 deletion or exon 21 L858R point mutation), accompanied with Bim deletion or low activating EGFR mutation abundance.

Description:

BIM (bcl-2 interacting mediator of cell death) deletion polymorphism and low EGFR mutation abundance were poor clinical response markers to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in NSCLC patients who had EGFR mutations.This is a phase II clinical trial to investigate the efficacy of combination treatment for patients harboring above risk factors.

Advanced EGFR mutated NSCLC Patients with Bim deletion or EGFR low mutation abundance were randomized divided into following three treatment groups:

A: gefitinib 250mg Qd combined with doublet chemotherapy: pemetrexed (500mg/m²，day 1 ，intravenously) plus carboplatin (AUC=5,day 1,intravenously) every 21 days.

B: gefitinib 250mg Qd combined with apatinib 250mg/d intravenously per 21 days. C: gefitinib 250mg Qd

Secondary	safety evaluation	Safety observation indexes were listed as following: adverse events and serious adverse events (according to CommonTerminology Criteria Adverse Events Version 4.03), physical exam, vital signs(blood pressure, heart rate, respiratory rate,body temperature), weight variation, laboratory examination(hematology, blood biochemistry, urinalysis and so on), electrocardiograph(ECG),ultrasonic cardiogram(UCG), ect.	8 weeks

In addition, the baseline values of the two scores, the value of each visit, and the change value of the baseline were statistically described.	24 months
