Introduction: Advanced non-squamous non-small cell lung cancer (NsqNSCLC) progressing at the induction of a first-line of platin-based chemotherapy is a subgroup of patients with poor prognosis and few second-line treatment options., Materials and Methods: This single-stage phase II prospective multicenter open-label trial performed in platin-based refractory (i.e. progressing during induction phase of first-line platin-based chemotherapy) advanced NsqNSCLC assessed the efficacy of the nintedanib-docetaxel combination in second-line treatment. The primary endpoint was progression-free survival (PFS) rates at 12 weeks with a cut-off at 30% for ineffectiveness and 50% for minimal efficacy., Results: A total of 59 patients from 23 centers were included (mean age, 58.5 years; male gender, 73.6%; performance status 0-1, 100%; former/current smokers, 92.5%; adenocarcinoma, 92.5%, median platin-based first-line chemotherapy, 2). Nintedanib-docetaxel combination was administered for a median of 4 cycles. The rate of PFS at 12 weeks was 39.6% (95% CI, 28.2-56.8). Median PFS was 2.7 (95% CI, 1.4-4.1) months and one-year PFS was 11.8% (95% CI, 4.8-22.2). Median overall survival (OS) was 6.9 (95% CI, 4.3-8.2) months and 12-month OS was 32.1% (95% CI, 19.8-45.0); 18-month OS was 27.6% (95% CI, 16,1-40.4). Twenty-nine (53.7%) patients reported at least one serious treatment-related adverse events leading to permanent discontinuation of at least one study drug in 12 (22.2%) patients., Conclusion: The predefined minimal efficacy was not demonstrated. However, a number of NsqNSCLC patients refractory to first-line platin-based chemotherapy appeared to benefit from this combination., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Objectives: Immune checkpoint inhibitors have become the standard of care for metastatic non-small-cell lung cancer (NSCLC) progressing during or after platinum-based chemotherapy. Real-world clinical practice tends to represent more diverse patient characteristics than randomized clinical trials. We sought to evaluate overall survival (OS) outcomes in the total study population and in key subsets of patients who received nivolumab for previously treated advanced NSCLC in real-world settings in France, Germany, or Canada., Materials and Methods: Data were pooled from two prospective observational cohort studies, EVIDENS and ENLARGE, and a retrospective registry in Canada. Patients included in this analysis were aged ≥18 years, had stage IIIB/IV NSCLC, and received nivolumab after at least one prior line of systemic therapy. OS was estimated in the pooled population and in various subgroups using the Kaplan-Meier method. Timing of data collection varied across cohorts (2015-2019)., Results: Of the 2585 patients included in this analyses, 1235 (47.8 %) were treated in France, 881 (34.1 %) in Germany, and 469 (18.1 %) in Canada. Median OS for the total study population was 11.3 months (95 % CI: 10.5-12.2); this was similar across France, Germany, and Canada. The OS rate was 49 % at 1 year and 28 % at 2 years for the total study population. In univariable Cox analyses, the presence of epidermal growth factor receptor mutations in nonsquamous disease, liver, or bone metastases were associated with significantly shorter OS, whereas tumor programmed death ligand 1 expression and Eastern Cooperative Oncology Group performance status 0-1 were associated with significantly prolonged OS. Similar OS was noted across subgroups of age and prior lines of therapy., Conclusion: OS rates in patients receiving nivolumab for previously treated advanced NSCLC in real-world clinical practice closely mirrored those in phase 3 studies, suggesting similar effectiveness of nivolumab in clinical trials and clinical practice., (Copyright © 2021 Bristol Myers Squibb.

Introduction: Using immune-checkpoint inhibitors (ICIs) to manage cancer is associated with various immune-related adverse events. Central and/or peripheral neurological disorders are rare and potentially serious. We analyzed the characteristics of non-small-cell lung cancer (NSCLC) patients who developed immune-related encephalitis under anti-programmed-death protein-1 or its ligand (PD-1/PD-L1)., Methods: Clinical, biological and radiological characteristics of ICI-treated NSCLC patients with immune-related encephalitis, from 6 centers, were evaluated retrospectively., Results: The 6 centers included 9 patients: all men, all smokers, median (range) age 67 (48-77) years, 78% adenocarcinomas, first- or second-line ICI for 5 and 4 patients, respectively. Two patients had non-active cerebral metastases at ICI onset. A median of 5 (1-22) ICI infusions preceded neurological symptoms, the most frequent being confusion (78%), fever (45%) and cerebellar ataxia (33%). CSF analyses revealed a median white blood cell count of 22/mm 3 (1-210/mm 3 ), with hyperlymphocytosis in 8 patients and high protein levels in all. All bacteriological and virological analyses were negative. Cerebral MRI was considered normal for 5 patients; 4 patients had FLAIR hypersignals consistent with brain parenchyma inflammation. Three patients required intensive care. All patients received corticosteroids (different doses), a median of 8.5 (6-18) days post-onset. Corticosteroids achieved rapid symptom regression without sequelae in 8 patients. The last patient, with the longest time until corticosteroid introduction, died. ICIs were never restarted in any patient., Conclusion: Immune encephalitis, a rare but serious complication of anti-PD-1/PD-L1 therapy, carries a good prognosis when managed with early corticosteroids., Competing Interests: Declaration of Competing Interest This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors., (Copyright © 2020.

Objectives: Brigatinib is a next-generation ALK inhibitor initially developed in ALK-positive NSCLC pretreated with crizotinib., Materials and Methods: This retrospective multicentric study analyzed ALK-positive advanced NSCLC patients pretreated with at least one tyrosine-kinase inhibitor, including crizotinib, and enrolled in the brigatinib French early access program. The primary endpoint was investigator-assessed progression-free survival (PFS)., Results: 104 patients were included (mean age, 56.6 years; never smokers, 61.5%; adenocarcinoma, 98.1%). Patients had received a median of 3 previous treatment lines, including at least 2 ALK inhibitors (mainly crizotinib then ceritinib). At brigatinib initiation, 59.1% had performance status 0-1, 51.9% had ≥ 3 metastatic sites, 74.5% had central nervous system metastases (CNS) and 8.8% had carcinomatous meningitis. Median duration of brigatinib treatment was 6.7 (95% CI, 0.06-20.7) months. Median PFS was 6.6 (4.8-9.9) months for the entire population. For patients who received 2, 3-4 and >4 lines of treatment before brigatinib, PFS was 4.3 (2.5-8.9), 10.4 (5.9-13.9) and 3.8 (0.8-7.4) months, respectively. In the 91 evaluable patients, disease control rate was 78.2%. From brigatinib start, median overall survival was 17.2 (11.0-not reached) months. Among the 68 patients with progressive disease after brigatinib, CNS was involved in 29.4% of cases. Median OS from the diagnosis of NSCLC was 75.3 (38.2-174.6) months., Conclusion: These real-world results confirm the efficacy of brigatinib in a cohort of patients heavily pretreated for ALK-positive advanced NSCLC., (Copyright © 2019 Elsevier B.V.

Objectives The efficacy of osimertinib in pretreated patients with advanced non-small cell lung cancer (NSCLC) harboring EGFR T790 M resistance mutation was demonstrated in clinical trials. However, data on efficacy of osimertinib in real world remain rare. Materials and methods This retrospective multicentric study analyzed T790M-positive advanced NSCLC patients enrolled in French early access program for osimertinib. Patients were pretreated with first- or second-generation EGFR tyrosine-kinase inhibitor and for a majority with chemotherapy. Primary endpoints were progression-free survival (PFS) and overall survival (OS) from osimertinib initiation. Results 205 patients (mean age, 69.5 years; female, 68.8%; adenocarcinoma, 97.5%, never-smokers, 71.5%) were analyzed. Osimertinib was used in second and third line in 18.0% and 82.0% of patients, respectively. Median PFS was 12.4 (95% CI, 10.1-15.1) months. In patients with and without cerebral metastasis, PFS was 9.7 (7.7-13.5) and 15.1 (12.0-17.1) months (p = 0.21), respectively. PFS in second and third line or more was 12.6 (6.7-17.5) and 12.4 (9.7-15.3) months, respectively. Median PFS in patients with EGFR exon 19 deletion and exon 21 mutation was 13.5 (10.1-16.0) and 9.7 (7.4-13.2) months, respectively (p = 0.049). Median OS since osimertinib initiation was 20.5 (16.9-24.3) months: 23.1 (18.6-27.8) and 18.0 (12.2-22.2) months in patients without and with cerebral metastasis (p = 0.11); 17.5 (11.6-27.8) and 21.7 (17.3-24.3) months as second or third line of treatment or more (p = 0.46), respectively. Median OS in patients with EGFR exon 19 deletion and exon 21 mutation was 23.1 (18.6-25.7) and 15.3 (11.6-21.7) months, respectively (p = 0.03). Osimertinib dosage was modified in 8.0% of patients and definitively discontinued for adverse events in 5.9%. Fifty patients benefited from rebiopsy (persistence of T790 M mutation, 44.7%; C797S mutation, 21.1%; cMET amplification, 8.0%). Conclusion In pretreated patients with T790M-mutated advanced NSCLC, the efficacy of osimertinib appears similar in real-world setting to that of clinical trials., (Copyright © 2018 Elsevier B.V.

Introduction: Few data have been published on the optimal management of elderly patients with locally advanced non-small-cell lung cancers (La-NSCLC). This prospective, multicenter, phase II study was undertaken to evaluate the ability of a comprehensive geriatric assessment (CGA) to select the elderly La-NSCLC patients who potentially may benefit from concurrent radio-chemotherapy., Methods: The main inclusion criteria were: La-NSCLC, >70 years old, at least one measurable target, ECOG performance status (PS) 0/1 and normal CGA. Weekly cisplatin (30 mg/m 2 ) and oral vinorelbine (30 mg/m 2 ) were combined with standard thoracic radiotherapy (66 Gy, 33 fractions) for 6.5 weeks. The primary evaluation criterion was <15% clinically relevant grade >2 toxicity. Secondary criteria were response rates, overall survival (OS) and progression-free survival (PFS)., Results: Among the 49 patients screened, 40 were included: 87.5% men, median age: 75.1 (70-84) years, 67.5% with PS 0, 52.5% squamous cell carcinomas. The full concurrent regimen was administrated in 77.5% of the cases (chemotherapy: 85%, radiotherapy: 90%); 22.5% of the patients experienced toxicity grade >2 (with three treatment-imputed deaths), 15% when restricted to clinically relevant >2 grade toxicities. One (2.6%) patient achieved a complete response, 53.8% had partial responses and 35.9% stable disease. Median PFS was 15 (95%CI: 8,7-35,2) months, OS 21.8 (95%CI: 16-NR) months and 1-, 2- and 4-year survival rates were 77.5%, 45% and 34.8%., Conclusion: CGA was able to select fit elderly patients with La-NSCLCs eligible for concurrent chemoradiotherapy with a satisfactory risk/benefit ratio., (Copyright © 2018 Elsevier B.V.

Objectives: In advanced non-small cell lung cancer (NSCLC), maintenance therapy has emerged as a novel therapeutic reference for patients with non-progressive disease after platinum-based induction chemotherapy. However, the use of double maintenance (DM) with pemetrexed and bevacizumab is still being evaluated in terms of its clinical benefits and safety profile. The objective of this retrospective study was to describe the reasons for DM discontinuation in a real-world setting., Materials and Methods: Patients with advanced non-squamous NSCLC were eligible if they had received at least 4 cycles of induction chemotherapy, followed by at least 1 cycle of DM. They were identified by using the oncology pharmacy database of 17 French centers., Results: Eighty-one patients who began a DM after induction chemotherapy were identified from September 2009 to April 2013. Among the 78 patients who had stopped DM at the time of the analysis, the main reasons for discontinuation were disease progression (42%), adverse events (33%), and personal preference (8%). The most frequent toxicity responsible for DM discontinuation was renal insufficiency (54%)., Conclusion: For patients with advanced NSCLC eligible for DM therapy, a particular attention should be paid to potential renal failure. Kidney function should be monitored carefully before and during DM to detect and manage early this adverse event., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

Objectives: When advanced non-small-cell lung cancer (NSCLC) progresses during first-line treatment, re-biopsy may be indicated to detect a possible new biological profile (comparison to initial status, emergence of resistance biomarkers, or assessment of new biomarkers). The aim of this pragmatic prospective multicenter study was to assess the feasibility and clinical utility of re-biopsy in advanced NSCLC in a real-world setting., Methods: The main inclusion criteria were advanced NSCLC with an indication for repeat biopsy identified by the patient's clinician. The primary outcome was the percentage of successful procedures. Secondary outcomes were the type of procedure, new biological status, tolerability of the procedure, and clinical utility (treatment modification)., Results: From May 2012 to May 2013, 18 centers enrolled 100 patients (males: 44%; median age: 64.8 years; PS 0/1: 88%; adenocarcinoma: 89%; EGFR mutated: 50%; no initial biological profile: 16.4%). Re-biopsy was not possible in 19.5% of cases and provided no or too few tumor cells in 25.6% of cases. Repeat biopsy was useful for guiding treatment in 30.4% (25/82) of cases. Complications were infrequent (2 cases of moderate bleeding and 1 case of pneumothorax)., Conclusion: Re-biopsy of advanced NSCLC is feasible in the real-world setting, with acceptable adverse events. Guidelines are needed on the indications of re-biopsy, the choice of procedure, the sampling site, and laboratory analysis., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)
