Sequential chemotherapy and icotinib as first-line treatment for advanced epidermal growth factor receptor-mutated non-small cell lung cancer.

ABSTRACT:

Background

Icotinib could have potential effect and tolerability when used sequentially with chemotherapy for advanced epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC).

Aim

To evaluate the efficacy and safety of chemotherapy followed by icotinib maintenance therapy as first-line treatment for advanced EGFR-mutated NSCLC.

Methods

This multicenter, open-label, pilot randomized controlled trial enrolled 68 EGFR-mutated stage IIIB/IV NSCLC patients randomized 2:3 to the icotinib alone and chemotherapy + icotinib groups.

Results

The median progression-free survival in the icotinib alone and chemotherapy + icotinib groups was 8.0 mo (95%CI: 3.84-11.63) and 13.4 mo (95%CI: 10.18-16.33), respectively (P = 0.0249). No significant differences were found in the curative effect when considering different cycles of chemotherapy or chemotherapy regimen (all P > 0.05).

Conclusion

A sequential combination of chemotherapy and EGFR-tyrosine kinase inhibitor is feasible for stage IV EGFR-mutated NSCLC patients.

Project description:ObjectiveTo compare the efficacy and safety of first line treatments for patients with advanced epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC).DesignSystematic review and network meta-analysis.Data sourcesPubMed, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and several international conference databases, from inception to 20 May 2019.Eligibility criteria for selecting studiesPublished and unpublished randomised controlled trials comparing two or more treatments in the first line setting for patients with advanced EGFR mutated NSCLC were included in a bayesian network meta-analysis. Eligible studies reported at least one of the following clinical outcome measures: progression free survival, overall survival, objective response rate, and adverse events of grade 3 or higher.Results18 eligible trials involved 4628 patients and 12 treatments: EGFR tyrosine kinase inhibitors (TKIs; osimertinib, dacomitinib, afatinib, erlotinib, gefitinib, and icotinib), pemetrexed based chemotherapy, pemetrexed free chemotherapy, and combination treatments (afatinib plus cetuximab, erlotinib plus bevacizumab, gefitinib plus pemetrexed based chemotherapy, and gefitinib plus pemetrexed). Consistent with gefitinib plus pemetrexed based chemotherapy (hazard ratio 0.95, 95% credible interval 0.72 to 1.24), osimertinib showed the most favourable progression free survival, with significant differences versus dacomitinib (0.74, 0.55 to 1.00), afatinib (0.52, 0.40 to 0.68), erlotinib (0.48, 0.40 to 0.57), gefitinib (0.44, 0.37 to 0.52), icotinib (0.39, 0.24 to 0.62), pemetrexed based chemotherapy (0.24, 0.17 to 0.33), pemetrexed free chemotherapy (0.16, 0.13 to 0.20), afatinib plus cetuximab (0.44, 0.28 to 0.71), and gefitinib plus pemetrexed (0.65, 0.46 to 0.92). Osimertinib and gefitinib plus pemetrexed based chemotherapy were also consistent (0.94, 0.66 to 1.35) in providing the best overall survival benefit. Combination treatments caused more toxicity in general, especially erlotinib plus bevacizumab, which caused the most adverse events of grade 3 or higher. Different toxicity spectrums were revealed for individual EGFR-TKIs. Subgroup analyses by the two most common EGFR mutation types indicated that osimertinib was associated with the best progression free survival in patients with the exon 19 deletion, and gefitinib plus pemetrexed based chemotherapy was associated with the best progression free survival in patients with the Leu858Arg mutation.ConclusionsThese results indicate that osimertinib and gefitinib plus pemetrexed based chemotherapy were associated with the best progression free survival and overall survival benefits for patients with advanced EGFR mutated NSCLC, compared with other first line treatments. The treatments resulting in the best progression free survival for patients with the exon 19 deletion and Leu858Arg mutations were osimertinib and gefitinib plus pemetrexed based chemotherapy, respectively.Systematic review registrationPROSPERO CRD42018111954.

Project description:To explore a better treatment strategy for patients with advanced non-small cell lung cancer harboring sensitive epidermal growth factor receptor mutations, a total of 271 patients were retrospectively analyzed. The patients were divided into two groups: the combination group (58 cases), which received concurrent icotinib, pemetrexed, and platinum treatment, and the sequential group (213 cases), which received the sequential pemetrexed and platinum therapy, followed by icotinib treatment. The primary end points were progression-free survival (PFS) and PFS on the subsequent line of therapy (PFS2). PFS in the combination group was significantly higher compared with that in the sequential group (16.89 months vs. 9.90 months; p < 0.001). PFS in the combination group was also significantly higher than PFS2 in the sequential group (16.89 months vs. 14.05 months; p = 0.009). The overall survival (OS) of the patients was 33.22 months (95% confidence interval (CI): 26.99-37.01) in the combination group and 26.47 months (95% CI: 25.05-26.95) in the sequential group (p < 0.001). The combination group's objective response rate was superior to that of the sequential group (79.31% vs. 52.11%; p < 0.001). Propensity score matching also revealed that icotinib therapy combined with chemotherapy extended the PFS, PFS2, and OS of the patients (p < 0.0001, p = 0.003, and p = 0.001, respectively). The combination group's objective response rate was also better compared with the sequential group (79.31% vs. 51.72%; p = 0.001). In conclusion, our study demonstrated icotinib combined with chemotherapy can improve survival efficacy better than the separated two-line therapy. Study Highlights WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC? For advanced non-small cell lung cancer (NSCLC) harboring activating EGFR mutants, EGFR-tyrosine kinase inhibitors (TKIs) are the standard first-line treatment. Unfortunately, most patients with NSCLC harboring EGFR mutations acquire EGFR-TKI resistance after EGFR-TKI treatment for about 10-14 months. Studies have indicated that chemotherapy plus EGFR-TKIs may have combined effects on the growth of NSCLC cells. However, until now, there has been no study comparing the concurrent and sequential EGFR-TKIs plus chemotherapy. WHAT QUESTION DID THIS STUDY ADDRESS? We retrospectively analyzed the efficacy and safety of concurrent versus sequential icotinib and chemotherapy in untreated NSCLC with sensitive EGFR mutations. WHAT DOES THIS STUDY ADD TO OUR KNOWLEDGE? In the patients with NSCLC with sensitive EGFR mutations, the first-line pemetrexed plus platinum combined with icotinib better improved PFS, PFS2, and objective response rate compared with first-line icotinib and second-line pemetrexed plus platinum. HOW MIGHT THIS CHANGE CLINICAL PHARMACOLOGY OR TRANSLATIONAL SCIENCE? The results of this paper provide guidance for the strategy choice in the treatment of patients with NSCLC.

Project description:ObjectiveEpidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are the current standard of care for advanced or metastatic non-small cell lung cancer (NSCLC) patients harboring EGFR activating mutations. However, the optimal strategy for elderly NSCLC patients is still under debate. This study was designed to explore the optimal first-line regimens by comparing diverse strategies for elderly and non-elderly EGFR-mutated NSCLC patients.MethodsA systematic review was conducted to summarize all available randomized controlled trials (RCTs) from PubMed, EMBASE, Cochrane Central Register of Controlled Trials databases, and international conferences before September 30, 2020. The primary outcome was progression free survival (PFS), and the secondary outcome was overall survival (OS). A network meta-analysis (NMA) was constructed using the Bayesian statistical model to synthesize the survival outcomes of all the treatments.ResultsIn total, 12 RCTs were deemed eligible for inclusion with 3779 patients who have received 10 diverse treatments including EGFR-TKIs. Results from the Bayesian ranking suggested that osimertinib was most likely to rank the first in overall population and in elderly patients in PFS, with the cumulative probabilities of 42.20% and 31.46%, respectively. In non-elderly group (younger than 65 years old), standard of care (SoC, representing first-generation EGFR-TKIs in this NMA) + chemotherapy ranked the first (31.66%). As for OS, SoC + chemotherapy ranked first in all patients (64.33%), patients younger than 65 years old (61.98%), or older than 65 years old (34.45%).ConclusionThe regimen of osimertinib is associated with the most favorable PFS in elderly advanced EGFR-mutated NSCLC patients, while SoC + chemotherapy is the optimal strategy in PFS for non-elderly NSCLC patients harboring EGFR activating mutations, and in OS for both elderly and non-elderly EGFR-mutated advanced NSCLC patients.Trial registrationINPLASY protocol 2020100061 https://doi.org/10.37766/inplasy2020.20.0061 .

Project description:ObjectivesRecent studies showed prolonged survival for advanced epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) patients treated with both monotherapies and combined therapies. However, high costs limit clinical applications. Thus, we conducted this cost-effectiveness analysis to explore an optimal first-line treatment for advanced EGFR-mutant NSCLC patients.Materials and methodsSurvival data were extracted from six clinical trials, including ARCHER1050 (dacomitinib vs. gefitinib); FLAURA (osimertinib vs. gefitinib/erlotinib); JO25567 and NEJ026 (bevacizumab +erlotinib vs. erlotinib); NEJ009 (gefitinib +chemotherapy vs. gefitinib); and NCT02148380 (gefitinib +chemotherapy vs. gefitinib vs. chemotherapy) trials. Cost-related data were obtained from hospitals and published literature. The effect parameter (quality-adjusted life year [QALY]) was the reflection of both survival and utility. Incremental cost-effectiveness ratio (ICER), average cost-effectiveness ratio (ACER), and net benefit were calculated, and the willingness-to-pay (WTP) threshold was set at $30828/QALY from the perspective of the Chinese healthcare system. Sensitivity analysis was performed to explore the stability of results.ResultsWe compared treatment groups with control groups in each trial. ICERs were $1897750.74/QALY (ARCHER1050), $416560.02/QALY (FLAURA), -$477607.48/QALY (JO25567), -$464326.66/QALY (NEJ026), -$277121.22/QALY (NEJ009), -$399360.94/QALY (gefitinib as comparison, NCT02148380), and -$170733.05/QALY (chemotherapy as comparison, NCT02148380). Moreover, ACER and net benefit showed that the combination of EGFR-TKI with chemotherapy and osimertinib was of more economic benefit following first-generation EGFR-TKIs. Sensitivity analyses showed that the impact of utilities and monotherapy could be cost-effective with a 50% cost reduction.ConclusionFirst-generation EGFR-TKI therapy remained the most cost-effective treatment option for advanced EGFR-mutant NSCLC patients. Our results could serve as both a reference for both clinical practice and the formulation of medical insurance reimbursement.
