Efficacy and Safety of Epidermal Growth Factor Receptor (EGFR)-Tyrosine Kinase Inhibitor Combination Therapy as First-Line Treatment for Patients with Advanced EGFR-Mutated, Non-Small Cell Lung Cancer: A Systematic Review and Bayesian Network Meta-Analysis.

ABSTRACT: (1) Background: Several randomized controlled trials (RCTs) have been conducted in combination with Efficacy and Safety of Epidermal Growth Factor Receptor(EGFR)-Tyrosine Kinase Inhibitor (TKI) for the first-line treatment of patients with advanced non-small cell lung cancer; however, head-to-head comparisons of combination therapies are still lacking. Therefore, this study aims to compare the efficacy and safety of various combination treatments. (2) Methods: We conducted a systematic review and Bayesian network meta-analysis by searching MEDLINE, EMBASE, and COCHRANE for relevant RCTs. (3) Results: TKI combined with antiangiogenic therapy, chemotherapy, or radiation achieved a significant benefit compared with TKI alone for progression free survival (PFS). A combination with radiation yielded better benefits in PFS than any other treatment. In terms of overall survival (OS), only the combination with pemetrexed and carboplatin (HR = 0.63, 95% credible interval 0.43-0.86)/radiation (0.44, 0.23-0.83) was superior to TKI alone. All of the combination therapies may increase the incidence of ≥Grade 3 AEs, as the pooled RRs are over 1; different toxicity spectrums were revealed for individual treatments. (4) Conclusions: The TKI combination of radiation/pemetrexed and carboplatin could provide the best antitumor effects among the first generation TKI-based treatments. Considering safety, ramucirumab and bevacizumab may be the ideal additions to TKIs (systematic review registration: PROSPERO CRD42022350474).

Project description:BackgroundIn the phase 3 FLAURA trial, osimertinib was compared with first-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) as a first-line treatment for EGFR-mutant non-small cell lung cancer (NSCLC). Osimertinib showed longer progression-free survival (PFS), overall survival (OS), and a similar safety profile. However, more studies demonstrating the effectiveness and safety of osimertinib as a first-line strategy are needed in real-world populations.MethodsWe enrolled 1,556 patients with EGFR-mutated stage IIIc-IV NSCLC from the CAPTRA-Lung database. All patients received either osimertinib (n=202) or a first-generation EGFR-TKI (n=1,354) as their initial treatment. To adjust for differences in baseline characteristics between two groups, 1:2 propensity score matching (PSM) was performed. Propensity scores included gender, age, Eastern Cooperative Oncology Group performance status score, smoking history, family history of tumor, pathology, EGFR mutations, and central nervous system (CNS) metastases. The standardized mean differences (SMD) before and after PSM were calculated to examine the balance of covariate distributions between two groups.ResultsAfter PSM, 202 patients receiving osimertinib and 404 patients receiving first-generation EGFR-TKIs were finally identified. SMD of each matched variable is less than 0.10. The median PFS was 19.4 months [95% confidence interval (CI): 14.3-24.4] in the osimertinib arm and 10.9 months (95% CI: 9.3-12.5) in the comparator arm [hazard ratio (HR) for progression, 0.47; 95% CI: 0.38-0.59; P<0.001). The median OS was 40.5 months (95% CI: 27.1-54.0) vs. 34.3 months (95% CI: 30.6-38.0) in two groups, respectively (HR for death, 0.76; 95% CI: 0.58-1.00; P=0.045). The incidence of grade 3 adverse events (AEs) between the two groups was 1% and 4.2%, respectively. No grade 4 AEs and treatment-related deaths were reported in both groups.ConclusionsIn real-world settings, osimertinib demonstrates longer PFS and OS, with a similar safety profile to that of comparator EGFR-TKIs when used as a first-line strategy in NSCLC patients.

Project description:BackgroundIn the global FLAURA study, first-line osimertinib, a third-generation irreversible tyrosine kinase inhibitor (TKI) of epidermal growth factor receptor (EGFR), significantly improved progression-free survival (PFS) and overall survival (OS) versus comparator EGFR TKIs in patients with EGFR mutation-positive (EGFRm) advanced non-small-cell lung cancer (NSCLC).ObjectiveThe FLAURA China study assessed first-line osimertinib in Chinese patients with EGFRm advanced NSCLC (NCT02296125).MethodsFLAURA China was a double-blind, randomized, phase III study. Adults from mainland China with previously untreated EGFRm (Exon 19 deletion or L858R) advanced NSCLC were enrolled in the global study or a China-only study under the same protocol; 136 patients were randomized to osimertinib (80 mg once daily [od]; n = 71) or comparator EGFR TKI (gefitinib or erlotinib; all sites selected gefitinib 250 mg od; n = 65). Patients were randomized and allocated to treatment groups by a central computer system. Treatment continued until disease progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint was investigator-assessed PFS; OS was a secondary endpoint.ResultsAll 136 randomized patients were analyzed. Osimertinib extended median PFS by 8.0 months versus comparator EGFR TKI (17.8 vs. 9.8 months; hazard ratio [HR] 0.56; 95% confidence interval [CI] 0.37-0.85). Median OS was 33.1 months in the osimertinib group versus 25.7 months in the comparator group (HR 0.85; 95% CI 0.56-1.29). At 3 years, 20% of patients on osimertinib and 8% on the comparator remained on randomized treatment. Grade 3 or higher adverse events (AEs) were reported in 54 and 28% of patients in the osimertinib and comparator groups, respectively, driven by increased local reporting of laboratory- and disease-related AEs. No new safety signals were identified.ConclusionsFirst-line osimertinib treatment resulted in a clinically meaningful PFS and OS benefit versus comparator EGFR TKI in Chinese patients with EGFRm advanced NSCLC. Safety data were consistent with the known safety profile of osimertinib.Clinical trial registrationClinicalTrials.gov NCT02296125, registered 20 November 2014.

Project description:BackgroundThis study aimed to investigate the efficacy of immunotherapy, as monotherapy or in combination, comparing to chemotherapy with or without anti-angiogenesis for advanced non-small cell lung cancer (NSCLC) patients progressing to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs).MethodsWe retrospectively analyzed patients with advanced NSCLC harboring EGFR mutations who received immune checkpoint inhibitors (ICI) and/or chemotherapy after EGFR-TKIs failure at Shanghai Chest Hospital between Aug 2016 and Oct 2022. According to the subsequent immunotherapy regimen, the patients were assigned to ICI monotherapy (IM), IO plus anti-angiogenesis (IA), ICI plus chemotherapy (IC), ICI plus chemotherapy plus anti-angiogenesis (ICA). Eligible patients undergoing standard chemotherapy were assigned to chemotherapy plus anti-angiogenesis (CA) and chemotherapy alone (CM). Efficacy was evaluated according to the RECIST 1.1version, and calculated the objective response rate (ORR) and disease control rate (DCR). Survival curves were plotted using the Kaplan-Meier method, and the median progression-free survival (PFS) was calculated. Differences among survival curves of the six groups were assessed using the log-rank test.ResultsA total of 237 advanced NSCLC patients with EGFR mutations were included in this study. Of the 160 patients who received immunotherapy, 57 received ICI monotherapy, 27 received ICI plus anti-angiogenesis therapy, 43 received ICI plus chemotherapy, and 33 received ICI plus anti-angiogenesis plus chemotherapy. 77 patients received standard chemotherapy, of which 30 received chemotherapy plus anti-angiogenesis and 47 received chemotherapy alone. Patients in ICA group showed significant longer PFS than IM (7.2 vs 1.9 months, P=0.011), IA (7.2 vs 4.8 months, P=0.009) and CM group (7.2 vs 4.4 months, P=0.005). There was no significant difference in PFS between the ICA and IC (7.2 vs 5.6 months, P=0.104) or CA (7.2 vs 6.7 months, P=0.959) group. Meanwhile, the ICA group showed the highest ORR and DCR (36.4% and 90.9%) compared to the other five groups. The IC group had a higher ORR than the IA and CA group (32.6% vs 7.4% vs 10.0%, respectively), but the DCR was comparable (79.1% vs 74.1% vs 76.7%, respectively). The ORR of the CM group was 6.4% and the DCR was 66.0%. IM group showed the lowest ORR and DCR (1.8% and 36.8%). Treatment-related adverse events (TRAEs) of grade 3 or worse occurred in 9 (27.3%) patients in the ICA group, 6 (20.0%) in the CA group, 7 (14.9%) in the CM group, 5 (11.6%) in the IC group, 5 (8.8%) in the IM group, and 2 (7.4%) in the IA group.ConclusionNSCLC patients with positive EGFR mutations after EGFR-TKIs failure received subsequent immunotherapy plus anti-angiogenesis and chemotherapy are likely to have more benefits in ORR, DCR and mPFS.
