Abstract
Osimertinib has demonstrated efficacy in patients with epidermal growth factor receptor (EGFR) T790M-positive non-small cell lung cancer (NSCLC) in clinical trials. However, real-world data on its effectiveness remain scarce. Taiwanese patients with T790M-positive locally advanced or metastatic NSCLC and progressive disease following treatment with at least one EGFR tyrosine kinase inhibitor (TKI) were enrolled from the osimertinib early access program. Of the 419 patients (mean age, 63 years; female, 67%), 53% were heavily pretreated (≥ third-line [3L]), making osimertinib a fourth-line (4L) intervention. The median progression-free survival (PFS) was 10.5 months (95% confidence interval [CI]: 8.95-11.41); the 18-month PFS rate was 26.5%. The median overall survival (OS) was 19.0 months (95% CI: 16.30-20.95); the 24-month OS rate was 40.9%. The objective response rate was 32.46%, and the disease control rate was 86.38%. The median time to treatment discontinuation of osimertinib monotherapy was 11.9 months (95% CI: 10.49-13.11). Subgroup analyses of median PFS and OS in the chemotherapy combination group vs. the osimertinib monotherapy group yielded no difference. Central nervous system (CNS) metastasis, number of prior lines of therapy, and types of initial EGFR-TKIs did not significantly impact outcomes. The median PFS values were 9.0 (95% CI: 5.18-11.34) and 10.9 (95% CI: 9.18-11.90) months with and without CNS metastasis, respectively, and 10.8 (95% CI: 8.59-12.69), 13.6 (95% CI: 10.89-16.3), and 9.2 (95% CI: 7.8-10.62) months for second-line (2L), 3L, and ≥4L therapy, respectively. In patients who received osimertinib as 2L therapy, the median PFS values in response to prior afatinib, erlotinib and gefitinib treatment were 11.2 (95% CI: 4.85-4.79), 10.5 (95% CI: 8.59-20.26) and 8.7 (95% CI: 7.21-16.79) months, respectively. Overall, real-world data from Taiwan support the clinical benefits of osimertinib in EGFR T790M -positive NSCLC.

Factors associated with outcomes of second-line treatment for EGFR-mutant non-small-cell lung cancer patients after progression on first- or second-generation EGFR-tyrosine kinase inhibitor treatment. Front Oncol 2023; 13:1104098. [PMID: 37409246 PMCID: PMC10318893 DOI: 10.3389/fonc.2023.1104098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 05/30/2023] [Indexed: 07/07/2023] Open
Abstract
Purpose Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are standard first-line treatments for advanced EGFR-mutant non-small-cell lung cancer (NSCLC) patients. However, factors associated with outcomes after progression on first-line therapy are seldom investigated. Materials and methods From January 2016 to December 2020, we enrolled 242 EGFR-mutant stage IIIB-IV NSCLC patients who progressed on first- or second-generation EGFR-TKI treatments, and 206 of them receive second-line treatments after disease progression. The factors that predict the survival outcomes of different second-line treatments after disease progression were evaluated. Clinical and demographic characteristics, including metastatic sites, neutrophil-to-lymphocyte ratio (NLR) at first-line progression, and second-line treatment regimens, and whether re-biopsied after disease progression or not, were reviewed for outcome analysis. Results The univariate analysis showed that the PFS was shorted in male patients (p =0.049), patients with ECOG performance state ≥ 2 (p =0.014), former smokers (p =0.003), patients with brain metastasis (p =0.04), second-line chemotherapy or EGFR-TKIs other than osimertinib (p =0.002), and NLR ≥5.0 (p=0.024). In addition, second-line osimertinib was associated with longer OS compared to chemotherapy and other EGFR-TKI treatment (p =0.001). In the multivariate analysis, only second-line osimertinib was an independent predictor of PFS (p =0.023). Re-biopsy after first-line treatment was associated with a trend of better OS. Patients with NLR ≥5.0 at disease progression had shorter OS than patients with NLR <5.0 (p = 0.008). Conclusion The benefits of osimertinib necessitate that aggressive re-biopsy after progression on first- or second-generation EGFR-TKI treatment is merited for appropriate second-line treatments to provide better outcomes for these patients.

Study Design and Rationale for the PACE-LUNG Trial: A Multicenter, Single-Arm, Phase II Clinical Trial Evaluating the Efficacy of Additional Chemotherapy for Patients with EGFRm NSCLC with the Continued Presence of Plasma ctDNA EGFRm at Week 3 After Start of Osimertinib First-Line Treatment. Clin Lung Cancer 2022; 23:e473-e477. [PMID: 36089483 DOI: 10.1016/j.cllc.2022.07.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/24/2022] [Accepted: 07/09/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Tyrosine kinase inhibitors (TKI) targeting the epidermal growth factor receptor (EGFR) like the third-generation TKI osimertinib have substantially improved the treatment of patients with advanced non-small cell lung cancer (NSCLC) harboring sensitizing EGFR mutations. However, there is a subset of patients that do not benefit from these therapies in terms of response rate or progression-free-survival (PFS). It has been shown that persistence of EGFR mutations in circulating tumor DNA (ctDNA) at weeks 3 and 6 after start of osimertinib predicts shorter PFS. These patients may benefit from additional chemotherapy. While combination therapies with older TKI have been demonstrated effective in improving outcome, they are associated with a significant increase in toxicity. PATIENTS AND METHODS PACE-LUNG is a multicenter, single-arm, investigator initiated, phase II trial conducted with the German national Network Genomic Medicine (nNGM). Patients with stage IIIB or IV NSCLC and exon 19 deletion or p.L858R EGFR mutation not amenable to curative treatment with persisting ctDNA after 3 to 4 weeks of first-line osimertinib monotherapy will receive additional chemotherapy (4 cycles of either cisplatin/pemetrexed or carboplatin/pemetrexed). Afterwards, osimertinib will be continued as standard of care until disease progression or intolerable toxicity. The primary endpoint is PFS. Secondary endpoints include overall survival, response rate, safety, and quality of life. Concomitant translational research will be performed to identify patterns of mutational evolution in ctDNA upon disease progression or ctDNA persistence. Enrollment started in December 2021. DISCUSSION The PACE-LUNG trial is designed to evaluate the efficacy and safety of a biomarker-driven strategy for therapy escalation in patients at high risk for early treatment failure. This approach aims not only to improve treatment outcomes, but also to limit the anticipated additional toxicity to high-risk patients. TRIAL REGISTRATION NUMBER 2019-004757-88 (EudraCT).

Abstract
BACKGROUND AURA study reported 61% objective response rate and progression-free survival of 9.6 months with osimertinib in patients with EGFR/T790M+ non-small cell lung cancer. Due to lack of real-world data, we proposed this study to describe the experience with osimertinib in Spain. METHODS Post-authorization, non-interventional Special Use Medication Program, multicenter, retrospective study in advanced EGFR/T790M+ non-small cell lung cancer. One hundred-fifty five patients were enrolled (August 2016-December 2018) from 30 sites. PRIMARY OBJECTIVE progression-free survival. Secondary objectives: toxicity profile, objective response rate, and use of health service resources. RESULTS 70% women, median age 66. 63.9% were non-smokers and 99% had adenocarcinoma. Most patients had received at least one prior treatment (97%), 91.7% had received previous EGFR-tyrosine kinase inhibitors and 2.8% osimertinib as first-line treatment. At data cutoff, median follow-up was 11.8 months. One hundred-fifty five patients were evaluable for response, 1.3% complete response, 40.6% partial response, 31% stable disease and 11.6% disease progression. Objective response rate was 42%. Median progression-free survival was 9.4 months. Of the 155 patients who received treatment, 76 (49%) did not reported any adverse event, 51% presented some adverse event, most of which were grade 1 or 2. The resource cost study indicates early use is warranted. CONCLUSION This study to assess the real-world clinical impact of osimertinib showed high drug activity in pretreated advanced EGFR/T790M+ non-small cell lung cancer, with manageable adverse events.

Abstract
BACKGROUND Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is the primary treatment in treating with EGFR mutant nonsmall cell lung cancer (NSCLC). This systematic review and meta-analysis aimed to evaluate the efficacy and safety of the third-generation EGFR-TKI, osimertinib, and summarize the risk factors associating with outcome after osimertinib treatment. METHOD The Ovid Medline, Embase, Cochrane Library, and Pubmed were systematically searched due to December 10, 2019. All the studies that mentioned the overall survival (OS), progression-free survival (PFS), treatment response, and adverse events (AEs) of osimertinib were involved in our study. Hazard ratio (HR) with 95% confidence intervals was used for comparing OS and PFS. RESULT A total of 47 studies were included in the systematic review, of which 14 studies were used to compare the efficacy between osimertinib and other EGFR-TKI or chemotherapy. Patients treating with osimertinib favors a higher OS and PFS in all the patients (HR = 0.56 and 0.38, P < .001, respectively), and in subgroup analysis, compared with other treatments. Median 55% T790 mutant NSCLC patients might experience partial response, and 25% of patients remained as stable disease. The incidence of severe AE ranged from 0% to 5%, and the most common severe AE was pneumonia (3%). Patients with the T858R mutation may have a better OS than Del 19 mutation (HR = 0.55, P = .037), while patients who have a smoking history may have a higher risk of progression than never-smoker patients (HR = 1.47, P = .028). CONCLUSION Osimertinib has an impressive antitumor activity compared with prior EGFR-TKI and chemotherapy with an acceptable response and tolerable AEs. EGFR mutation type and smoking status were the risk factors for mortality and progression in NSCLC patients.

The Status of the EGFR T790M Mutation is associated with the Clinical Benefits of Osimertinib Treatment in Non-small Cell Lung Cancer Patients: A Meta-Analysis. J Cancer 2020; 11:3106-3113. [PMID: 32231715 PMCID: PMC7097959 DOI: 10.7150/jca.38411] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Accepted: 11/30/2019] [Indexed: 01/26/2023] Open
Abstract
Background and Purpose: Pervious studies have demonstrated that the loss of EGFR T790M after Osimertinib treatment may be the cause of Osimertinib resistance. Here, we conducted a meta-analysis to evaluate the association between the persistence of EGFR T790M and the clinical benefits of Osimertinib in non-small cell lung cancer (NSCLC) patients with baseline EGFR T790M mutation. Experimental design and Methods: PUBMED, EMBASE, and Cochrane databases were searched for eligible studies that provided the survival outcomes including overall survival (OS), progression-free survival (PFS) or time to discontinuation (TTD) data for each patient treated with Osimertinib with the status of the T790M mutation tested after Osimertinib resistance. The hazard ratios (HRs) and their 95% confidence intervals (CI) were calculated for each study. Results: In total, eight eligible studies were included in the analysis, among which six studies provided the data on PFS, and the other two studies provided the TTD data. Overall, 312 patients (151 patients with the persistence of T790M) were identified. The persistence of T790M was associated with longer PFS (HR, 0.40; 95% CI, 0.19-0.84; P=0.01) and TTD (HR, 0.54; 95% CI, 0.39-0.76; P=0.0004). Furthermore, overall analysis the survival outcomes including PFS and TTD subgroups also showed preferable clinical benefits for patients with the T790M persistence (HR, 0.57; 95%CI, 0.45-0.73; P<0.00001). Conclusions: Our findings confirm the persistence of T790M is associated with the clinical benefits of Osimertinib in NSCLC patients with baseline EGFR T790M mutation treated with Osimertinib.

Efficacy of osimertinib for the treatment of previously EGFR TKI treated NSCLC patients: a meta-analysis. Clin Transl Oncol 2019; 22:892-899. [PMID: 31538306 DOI: 10.1007/s12094-019-02204-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 08/31/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND This study evaluates the efficacy of osimertinib for the treatment of previously epidermal growth factor receptor tyrosine kinase inhibitors (EFGR-TKI) treated non-small cell lung cancer (NSCLC) patients. METHOD Research articles reporting the efficacy of osimertinib for NSCLC patients were identified from literature databases (Embase, Ovid, PubMed and Scopus) by following pre-determined eligibility criteria. Response and survival data were extracted from study reports and were pooled under random-effects model to obtain overall/subgroup effect sizes of selected efficacy outcomes. RESULTS Nine studies (950 patients; age 60.1 years [95% confidence interval: 57.2, 63.1]; 65% [95% CI: 62, 69] females; 69% [35, 100] with T790M; 61% [53, 68] with ex19del; and 35% [29, 41] with L858R mutations). Osimertinib treatment was associated with a PFS of 11.17 months [7.80, 14.55] which was longer in treatment-naïve (20.30 [15.37, 25.23]) than in prior EGFR-TKI-treated (10.20 [9.60, 10.80]) patients. 1-year survival was 81.29% [73.25, 89.32]. Complete response rate was 1.48% [1.19, 1.76]. PR was achieved in 53.18% [24.18, 82.18] patients which differed between treatment-naïve and prior EGFR-TKI-treated patients (74.48 [65.59, 83.37] and 67.99% [62.68, 73.30], respectively. Objective response rate and disease control rates were 69.80% [64.84, 74.77] and 92.43% [89.42, 95.43], respectively, which did not differ between treatment-naïve and prior EGFR-TKI-treated patients. CONCLUSION Osimertinib treatment yields approximately 10 months PFS in prior EGFR-TKI-treated and 20 months in treatment-naïve NSCLC patients. Partial response rate is also higher in treatment-naïve patients. However, objective response rate (ORR) and disease control rate (DCR) did not differ between groups of patients.
