Gefitinib With Chemotherapy or Anti-angiogenesis in NSCLC Patients With Bim Deletion or Low EGFR Mutation Abundance

Gefitinib Versus Combination of Gefitinib With Chemotherapy or Anti-angiogenesis as 1st Line Treatment in Advanced NSCLC Patients Detected With Bim Deletion or Low EGFR Activating Mutation Abundance：A Randomized, Multicentre, Phase II Study

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.

Study Overview

• Status: Unknown
• Conditions: Non-small-cell Lung Cancer
• Intervention / Treatment: Drug: gefitinib combined with chemotherapy; Drug: gefitinib combined with apatinib; Drug: gefitinib single agent

Detailed 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
