EGFR-TKI Combined With Concurrent or Sequential Chemotherapy for Patients of Gradual Progression

Phase 2
Completed
Conditions
Lung Adenocarcinoma
EGFR Activating Mutation
Interventions
Drug: first icotinib and then pemetrexed plus cisplatin
Registration Number
NCT03544814
Lead Sponsor
Shanghai Chest Hospital
Brief Summary

To compare the efficacy of simultaneous EGFR-TKI and chemotherapy with that of sequential treatment after patients gradually progressed from first-line EGFR-TKI treatment.

Patients who had gradual progression and EGFR-T790M mutation-negative were randomly divided into two groups: in concurrent group, patients were treated with pemetrexed plus cisplatin along with the same EGFR-TKI; in sequential group, patients continued with EGFR-TKI until the disease progressed again according to the RECIST criteria, and then switched to chemotherapy. We evaluated progression-free survival (PFS) and overall survival (OS) time of patients. For sequential group, PFS was PFS1 (gradual progression to discontinue EGFR-TKI) plus PFS2 (chemotherapy alone).

Detailed Description

According to previous reports, when non-small cell lung cancer (NSCLC) patients with EGFR mutations gradually progressed after initial EGFR tyrosine-kinase inhibitor (TKI) treatment, continuing TKI therapy may be beneficial. We aimed to compare the efficacy of simultaneous EGFR-TKI and chemotherapy with that of sequential treatment after patients gradually progressed from first-line EGFR-TKI treatment.

Patients who had gradual progression and EGFR-T790M mutation-negative were randomly divided into two groups: in concurrent group, patients were treated with pemetrexed plus cisplatin along with the same EGFR-TKI; in sequential group, patients continued with EGFR-TKI until the disease progressed again according to the RECIST criteria, and then switched to chemotherapy. We evaluated progression-free survival (PFS) and overall survival (OS) time of patients. For sequential group, PFS was PFS1 (gradual progression to discontinue EGFR-TKI) plus PFS2 (chemotherapy alone). Objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety were also evaluated.

Primary Outcome Measures
NameTimeMethod
Progression-free survival (PFS)16 months

Radiographic assessments were performed when enrolled and every 8 weeks until disease progression after chemotherapy according to RECIST version 1.1. After PD, collect the survival information every 16 weeks until death or withdrawal of study consent.

Secondary Outcome Measures
NameTimeMethod
overall survival (OS)32 months

Radiographic assessments were performed when enrolled and every 8 weeks until disease progression after chemotherapy according to RECIST version 1.1. After PD, collect the survival information every 16 weeks until death or withdrawal of study consent.
