Association Between Lung Immune Prognostic Index and Durvalumab Consolidation Outcomes in Patients With Locally Advanced Non-Small-Cell Lung Cancer. Clin Lung Cancer 2024; 25:233-243.e8. [PMID: 38105153 DOI: 10.1016/j.cllc.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 11/07/2023] [Accepted: 11/13/2023] [Indexed: 12/19/2023]
Abstract
INTRODUCTION The LIPI, based on pretreatment derived neutrophils/[leukocytes-neutrophils] ratio (dNLR) and LDH, is associated with immune checkpoint inhibitors (ICI) outcomes in advanced non-small-cell lung cancer (NSCLC). We aimed to assess baseline LIPI correlation with durvalumab consolidation outcomes in the locally advanced setting. MATERIAL AND METHODS Multicentre retrospective study (330 patients) with stage III unresectable NSCLC treated with durvalumab after chemo-radiotherapy between April 2015 and December 2020; 65 patients treated with chemo-radiotherapy only. Baseline LIPI characterized 3 groups: good (dNLR≤3+LDH≤ULN), intermediate (dNLR>3/LDH>ULN) and poor (dNLR>3+LDH>ULN). Primary endpoint was overall survival (OS). RESULTS In the durvalumab cohort, median age was 67 years, 95% smokers, 98% with a performance status of 0-1; 60% had nonsquamous histology and 16% a PD-L1 expression <1%. Radiotherapy was delivered concurrently in 81%. LIPI was evaluable in 216 patients: 66% good, 31% intermediate, 3% poor. LIPI significantly correlated with median OS (median follow-up: 19 months): 18.1 months vs. 47.0 months vs. not reached in poor, intermediate and good LIPI groups, respectively (P = .03). A trend between objective response rate and LIPI groups was observed: 0% vs. 41% vs. 45%, respectively (P = .05). The pooled intermediate/poor LIPI group was associated with shorter OS (HR 1.97; P = .03) and higher risk of progressive disease (OR 2.68; P = .047). Survivals and response were not influenced in the control cohort. CONCLUSION Baseline LIPI correlated with outcomes in patients with locally advanced NSCLC treated with durvalumab consolidation, but not in those who only received chemo-radiotherapy, providing further evidence of its prognostic and potential predictive role of ICI benefit in NSCLC.

STK11/LKB1 alterations worsen the poor prognosis of KRAS mutated early-stage non-squamous non-small cell lung carcinoma, results based on the phase 2 IFCT TASTE trial. Lung Cancer 2024; 190:107508. [PMID: 38428265 DOI: 10.1016/j.lungcan.2024.107508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 02/14/2024] [Accepted: 02/18/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND STK11/LKB1 mutations have been associated with primary resistance to PD-1 axis inhibitors and poor prognosis in advanced KRAS-mutant lung adenocarcinoma. This study aimed to assess the prognostic significance of STK11/LKB1 alterations in localized non-squamous non-small cell lung carcinoma (non-sq NSCLC). PATIENTS AND METHODS Surgical samples from patients undergoing complete resection for stage IIa, IIb, or IIIa (N2 excluded) non-sq NSCLC in the randomized adjuvant phase II trial (NCT00775385 IFCT-1801 TASTE trial) were examined. Patients received either standard chemotherapy (Pemetrexed Cisplatin) or personalized treatment based on EGFR mutation (Erlotinib) and ERCC1 expression. Tumor molecular profiles were analyzed using targeted NGS and correlated with overall survival (OS) and disease-free survival (DFS), adjusting for relevant clinical variables. Additionally, interactions between treatment groups and molecular alterations on OS, PD-L1 expression, and tumor-circulating DNA in post-operative plasma samples were evaluated. RESULTS Among 134 patients (predominantly male smokers with adenocarcinoma), KRAS mutations were associated with shorter DFS (HR: 1.95, 95 % CI: 1.1-3.4, p = 0.02) and OS (HR: 2.32, 95 % CI: 1.2-4.6, p = 0.014). Isolated STK11/LKB1 mutations (n = 18) did not significantly impact DFS or OS. However, within KRAS-mutated samples (n = 53), patients with concurrent STK11/LKB1 mutations (n = 10) exhibited significantly shorter DFS (HR: 3.85, CI: 1.5-10.2, p = 0.006) and a trend towards shorter OS (HR: 1.80, CI: 0.6-5.3, p = 0.28). No associations were found between PD-L1 expression, other gene mutations, progression-free survival (PFS), or OS. CONCLUSION This analysis reinforces KRAS mutations as predictive factors for relapse and poor survival in localized non-sq NSCLC. Furthermore, the presence of concomitant STK11/LKB1 mutations exacerbated the prognosis within the KRAS-mutated subset. These findings emphasize the clinical relevance of these molecular markers and their potential impact on treatment strategies in non-sq NSCLC.

VEGFR2 and CD34 expression associated with longer survival in patients with pleural mesothelioma in the IFCT-GFPC-0701 MAPS phase 3 trial. Lung Cancer 2023; 182:107287. [PMID: 37393757 DOI: 10.1016/j.lungcan.2023.107287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/19/2023] [Accepted: 06/24/2023] [Indexed: 07/04/2023]
Abstract
OBJECTIVES VEGF/VEGFR autocrine loop is a hallmark of pleural mesothelioma (PM). We thus assayed the prognostic and predictive values of VEGFR-2 [vascular endothelial growth factor receptor 2 or Flk-1] and CD34, a marker of endothelial cells, in samples from patients accrued in the Mesothelioma Avastin Cisplatin Pemetrexed Study ('MAPS', NCT00651456). MATERIALS AND METHODS VEGFR2 and CD34 expression were assayed using immunohistochemistry in 333 MAPS patients (74.3%), and their prognostic value was evaluated in terms of overall survival (OS) and progression-free survival (PFS) in univariate and multivariate analyses, before validation by bootstrap methodology. RESULTS Positive VEGFR2 or CD34 staining was observed in 234/333 (70.2%) and 322/323 (99.6%) of tested specimens, respectively. VEGFR2 and CD34 staining correlated weakly, yet significantly, with each other (r = 0.36, p < 0.001). High VEGFR2 expression or high CD34 levels were associated with longer OS in PM patients in multivariate analysis (VEGFR2: adjusted [adj.] hazard ratio [HR]: 0.91, 95% confidence interval [CI] [0.88; 0.95], p < 0.001; CD34: adj. HR: 0.86, 95 %CI [0.76; 0.96], p = 0.010), with only high VEGFR2 expression resulting in significantly longer PFS (VEGFR2: adj. HR: 0.96, 95 %CI [0.92; 0.996], p = 0.032). Stability of these results was confirmed using bootstrap procedure. Nevertheless, VEGFR2 expression failed to specifically predict longer survival in bevacizumab-chemotherapy combination trial arm, regardless of whether the VEGFR2 score was combined or not with serum VEGF concentrations. CONCLUSION VEGFR2 overexpression independently correlated with longer OS or PFS in PM patients, such biomarker deserving prospective evaluation as stratification variable in future clinical trials.

Reduced risk of secondary primary extra pulmonary cancer in advanced/metastatic lung cancer patients treated with immune checkpoint inhibitors. Lung Cancer 2023; 182:107280. [PMID: 37339550 DOI: 10.1016/j.lungcan.2023.107280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 06/09/2023] [Accepted: 06/13/2023] [Indexed: 06/21/2023]
Abstract
BACKGROUND Lung cancer survivors are at high risk of developing a second primary cancer (SPC). We explored the Unicancer Epidemiology Strategy Medical-Economics for advanced or metastatic lung cancer (AMLC) database to assess the impact of immune checkpoint inhibitors (ICI) on the risk of SPC in patients with advanced/metastatic lung cancer. PATIENTS AND METHODS This retrospective study used data from patients with AMLC, with treatment initiated between January 1st 2015 and December 31st 2018. Patients with lung cancer as the second primary cancer were excluded and a 6-months landmark threshold was applied to exclude patients with synchronous SPC, patients dead without SPC or with a follow-up inferior to 6 months. A propensity score (PS) was calculated on the following baseline covariates: Age at locally advanced or metastatic diagnosis, sex, smoking status, metastatic status, performance status and histological type. The inverse probability of treatment weighting approach was used on the analyses aiming to assess the impact of ICI administered for AMLC, on the risk of occurrence of SPC. RESULTS Among the 10 796 patients, 148 (1.4%) patients had a diagnosis of SPC in a median interval of 22 (min-max: 7-173) months. All the patients (100%) with locally advanced or metastatic LC received at least one systemic treatment including (chemotherapy regimen (n = 9 851, 91.2%); ICI (n = 4 648, 43.0%); targeted treatment (n = 3 500; 32.4%). 40 (0.9%) SPC were reported in the 4 648 patients with metastatic LC treated with ICI vs 108 (1.7%) out of the 6 148 who did not receive immunotherapy (p < 0.0001). The multivariate analysis identified that treatment with ICI in patients with AMLC is associated with a reduced risk of SPC (HR = 0.40, 95% CI 0.27-0.58). CONCLUSION Treatment with ICI in AMLC patients was associated with a significantly reduced risk of SPC. Prospective studies are required to confirm these results.

Five-Year Survival Outcomes With Nivolumab Plus Ipilimumab Versus Chemotherapy as First-Line Treatment for Metastatic Non-Small-Cell Lung Cancer in CheckMate 227. J Clin Oncol 2023; 41:1200-1212. [PMID: 36223558 PMCID: PMC9937094 DOI: 10.1200/jco.22.01503] [Citation(s) in RCA: 77] [Impact Index Per Article: 77.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
PURPOSE We present 5-year results from CheckMate 227 Part 1, in which nivolumab plus ipilimumab improved overall survival (OS) versus chemotherapy in patients with metastatic non-small-cell lung cancer, regardless of tumor programmed death ligand 1 (PD-L1) status. METHODS Adults with stage IV/recurrent non-small-cell lung cancer without EGFR mutations or ALK alterations and with tumor PD-L1 ≥ 1% or < 1% (n = 1739) were randomly assigned. Patients with tumor PD-L1 ≥ 1% were randomly assigned to first-line nivolumab plus ipilimumab, nivolumab alone, or chemotherapy. Patients with tumor PD-L1 < 1% were randomly assigned to nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy. End points included exploratory 5-year results for efficacy, safety, and quality of life. RESULTS At a minimum follow-up of 61.3 months, 5-year OS rates were 24% versus 14% for nivolumab plus ipilimumab versus chemotherapy (PD-L1 ≥ 1%) and 19% versus 7% (PD-L1 < 1%). The median duration of response was 24.5 versus 6.7 months (PD-L1 ≥ 1%) and 19.4 versus 4.8 months (PD-L1 < 1%). Among patients surviving 5 years, 66% (PD-L1 ≥ 1%) and 64% (PD-L1 < 1%) were off nivolumab plus ipilimumab without initiating subsequent systemic anticancer treatment by the 5-year time point. Survival benefit continued after nivolumab plus ipilimumab discontinuation because of treatment-related adverse events, with a 5-year OS rate of 39% (combined PD-L1 ≥ 1% and < 1% populations). Quality of life in 5-year survivors treated with nivolumab plus ipilimumab was similar to that in the general US population through the 5-year follow-up. No new safety signals were observed. CONCLUSION With all patients off immunotherapy treatment for ≥ 3 years, nivolumab plus ipilimumab increased 5-year survivorship versus chemotherapy, including long-term, durable clinical benefit regardless of tumor PD-L1 expression. These data support nivolumab plus ipilimumab as an effective first-line treatment for patients with metastatic non-small-cell lung cancer.

First-line nivolumab plus ipilimumab for metastatic non-small cell lung cancer, including patients with ECOG performance status 2 and other special populations: CheckMate 817. J Immunother Cancer 2023; 11:jitc-2022-006127. [PMID: 36725084 PMCID: PMC9896179 DOI: 10.1136/jitc-2022-006127] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/30/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND CheckMate 817, a phase 3B study, evaluated flat-dose nivolumab plus weight-based ipilimumab in patients with metastatic non-small cell lung cancer (NSCLC). Here, in this research, we report on first-line treatment in patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1 (cohort A) and special populations (cohort A1: ECOG PS 2; or ECOG PS 0-1 with untreated brain metastases, renal impairment, hepatic impairment, or controlled HIV infection). METHODS Cohorts A and A1 received nivolumab 240 mg every 2 weeks plus ipilimumab 1 mg/kg every 6 weeks. The primary endpoint was the incidence of grade 3-4 and grade 5 immune-mediated adverse events (IMAEs; adverse events (AEs) deemed potentially immune-related, occurring <100 days of last dose, and treated with immune-modulating medication (except endocrine events)) and treatment-related select AEs (treatment-related AEs with potential immunological etiology requiring frequent monitoring/intervention, reported between first dose and 30 days after the last dose) in cohort A; efficacy endpoints were secondary/exploratory. In cohort A1, safety/efficacy assessment was exploratory. RESULTS The most common grade 3-4 IMAEs were pneumonitis (5.1%), diarrhea/colitis (4.9%), and hepatitis (4.6%) in cohort A (N=391) and diarrhea/colitis (3.5%), hepatitis (3.5%), and rash (3.0%) in cohort A1 (N=198). The most common grade 3-4 treatment-related select AEs were hepatic (5.9%), gastrointestinal (4.9%), and pulmonary (4.6%) events in cohort A and gastrointestinal (4.0%), skin (3.5%), and endocrine (3.0%) events in cohort A1. No grade 5 IMAEs or treatment-related select AEs occurred. Treatment-related deaths occurred in 4 (1.0%) and 3 (1.5%) patients in cohorts A and A1, respectively. Three-year overall survival (OS) rates were 33.7% and 20.5%, respectively. CONCLUSIONS Flat-dose nivolumab plus weight-based ipilimumab was associated with manageable safety and durable efficacy in cohort A, consistent with data from phase 3 metastatic NSCLC studies. Special populations of cohort A1 including patients with ECOG PS 2 or ECOG PS 0-1 with untreated brain metastases had manageable treatment-related toxicity and clinically meaningful 3-year OS rate.

Abstract
INTRODUCTION Nearly 1% to 2% of NSCLCs harbor RET fusions. Characterization of this rare population is still incomplete. METHODS This retrospective multicenter study included patients with any-stage RET positive (RET+) NSCLC from 31 cancer centers. Molecular profiling included DNA/RNA sequencing or fluorescence in situ hybridization analyses. Clinicobiological features and treatment outcomes (per investigator) with surgery, chemotherapy (CT), immune checkpoint blockers (ICBs), CT-ICB, multityrosine kinase inhibitors, and RET inhibitors (RETis) were evaluated. RESULTS For 218 patients included between February 2012 and April 2022, median age was 63 years, 56% were females, 93% had adenocarcinoma, and 41% were smokers. The most frequent fusion partner was KIF5B (72%). Median tumor mutational burden was 2.5 (range: 1-4) mutations per megabase, and median programmed death-ligand 1 expression was 10% (range: 0%-55%). The most common metastatic sites were the lung (50%), bone (43%), and pleura (40%). Central nervous system metastases were found at diagnosis of advanced NSCLC in 21% of the patients and at last follow-up or death in 31%. Overall response rate and median progression-free survival were 55% and 8.7 months with platinum doublet, 26% and 3.6 months with single-agent CT, 46% and 9.6 months with CT-ICB, 23% and 3.1 months with ICB, 37% and 3 months with multityrosine kinase inhibitor, and 76% and 16.2 months with RETi, respectively. Median overall survival was longer in patients treated with RETi versus no RETi (50.6 mo [37.7-72.1] versus 16.3 mo [12.7-28.8], p < 0.0001). CONCLUSIONS Patients with RET+ NSCLC have mainly thoracic and bone disease and low tumor mutational burden and programmed death-ligand 1 expression. RETi markedly improved survival, whereas ICB may be active in selected patients.

Abstract
INTRODUCTION We characterized the safety of first-line nivolumab plus ipilimumab (NIVO+IPI) in a large patient population with metastatic NSCLC and efficacy outcomes after NIVO+IPI discontinuation owing to treatment-related adverse events (TRAEs). METHODS We pooled data from three first-line NIVO+IPI studies (NIVO, 3 mg/kg or 240 mg every 2 wk; IPI, 1 mg/kg every 6 wk) in metastatic NSCLC (CheckMate 227 part 1, CheckMate 817 cohort A, CheckMate 568 part 1). Safety end points included TRAEs and immune-mediated adverse events (IMAEs) in the pooled population and patients aged 75 years or older. RESULTS In the pooled population (N = 1255), any-grade TRAEs occurred in 78% of the patients, grade 3 or 4 TRAEs in 34%, and discontinuation of any regimen component owing to TRAEs in 21%. The most frequent TRAE and IMAE were diarrhea (20%; grade 3 or 4, 2%) and rash (17%; grade 3 or 4, 3%), respectively. The most common grade 3 or 4 IMAEs were hepatitis (5%) and diarrhea/colitis and pneumonitis (4% each). Pneumonitis was the most common cause of treatment-related death (5 of 16). Safety in patients aged 75 years or older (n = 174) was generally similar to the overall population, but discontinuation of any regimen component owing to TRAEs was more common (29%). In patients discontinuing NIVO+IPI owing to TRAEs (n = 225), 3-year overall survival was 50% (95% confidence interval: 42.6-56.0), and 42% (31.2-52.4) of 130 responders remained in response 2 years after discontinuation. CONCLUSIONS First-line NIVO+IPI was well tolerated in this large population with metastatic NSCLC and in patients aged 75 years or older. Discontinuation owing to TRAEs did not reduce long-term survival.

Abstract
PURPOSE Targeted therapies (TT) and immune checkpoint blockers (ICB) have revolutionized the approach to non-small cell lung cancer (NSCLC) treatment in the era of precision medicine. Their impact as switch maintenance therapy based on molecular characterization is unknown. EXPERIMENTAL DESIGN SAFIR02-Lung was an open-label, randomized, phase 2 trial, involving 33 centers in France. We investigated eight TT (substudy-1) and one ICB (substudy-2), compared to standard-of-care as a maintenance strategy in advanced EGFR, ALK wild-type (wt) NSCLC patients without progression after first line chemotherapy, based on high-throughput genome analysis. The primary outcome was progression-free survival (PFS). RESULTS Among the 175 patients randomized in substudy-1, 116 received TT (selumetinib, vistusertib, capivasertib, AZD4547, AZD8931, vandetanib, olaparib, savolitinib) and 59 standard-of-care. Median PFS was 2.7 months (95% CI 1.6-2.9) with TT vs. 2.7 months (1.6-4.1) with standard-of-care (HR 0.97, 0.7-1.36; p=0.87). There were no significant differences in PFS within any molecular subgroup. In substudy-2, 183 patients were randomized, 121 received durvalumab and 62 standard-of-care. Median PFS was 3.0 months (2.3-4.4) with durvalumab versus 3.0 months (2.0-5.1) with standard-of-care (HR=0.86; 0.62-1.20; p=0.38). Preplanned subgroup analysis showed an enhanced benefit with durvalumab in patients with PD-L1 Tumor Proportion Score (TPS) ≥ 1%, (n=29, HR=0.29; 0.11-0.75) as compared to PD-L1 <1% (n=31, HR=0.71, 0.31-1.60, interaction p= 0.036). CONCLUSIONS Molecular profiling can feasibly be implemented to guide treatment choice for the maintenance strategy in EGFR/ALK wt NSCLC; in the current study it did not lead to substantial treatment benefits beyond durvalumab for PD-L1 ≥ 1 patients.

Abstract
Abstract
Introduction: RET fusions (RET+) are identified in nearly 1% of advanced NSCLC (aNSCLC). We evaluated characteristics and outcomes of patients (pts) with RET+ aNSCLC.
Methods: This is an international, multicenter, retrospective study evaluating clinical, biological, pathological and radiological data of pts with RET+ aNSCLC. Objective response rates (ORR), duration of response (DOR) and progression-free survival (PFS) were evaluated under double or single agent chemotherapy (CT), immunotherapy (ICI), CT-ICI, multityrosine kinase inhibitors (MTKi) and RET inhibitors (RETi). Overall survival (OS) was calculated from the start of first line therapy and compared between pts treated or not by RETi, after stratification by number of treatment lines.
Results: A total of 71 pts was included from 11 centers. Median age was 60 [IQR 47-69], 58% were female, 93% had adenocarcinoma, 2 pts (3%) had squamous and 2 (3%) neuroendocrine carcinoma, 38 (53.5%) were tobacco consumers (median 18.5 PY [7.8-31.3]), 50 (70%) had stage IV disease at diagnosis. Fusion partners were KIF5B (35/49, 71%), CCDC6 (9/49, 18%), others (5/49, 10%). Median TMB was 2.76 [2.0-8.5], median PD-L1 5% [0-29]. The most frequent co-mutation was TP53 (18/58 cases, 31%). Median number of metastatic sites was 2 [1-3], most commonly lung (48%), bone (45%), pleura (41%) and nodes (35%). Brain metastases were found in 18% of cases at diagnosis and in 31% at last follow-up or death. Table reports outcomes by treatment. mOS was 50.6 months [95%CI 37.6 - NR]. Fifty-two pts received 1st generation RETi. The use of RETi improved OS in pts treated with ≤2 lines of therapy (NR vs 17.8 months, p=0.024) and in those receiving >2 lines (50.6 vs 12.7 months, p=0.0037). Pts responding to ICI had a median PD-L1 of 85% [15.5-90].
Conclusions: Pts with RET+ aNSCLC have mainly thoracic and bone disease. Despite smoking history, median TMB and PD-L1 expression are low. ICI may have a significant activity in selected cases. RETi improve OS.

Abstract
Abstract
Background: Resistance to PD1/L1 immune checkpoint inhibitors (ICIs) in advanced NSCLC patients is observed in about 80% of individuals with no robust predictive biomarker yet. The PIONeeR trial (NCT03493581) aims to predict such resistances through a comprehensive multiparametric biomarkers analysis.
Methodology: Among the >300 advanced NSCLC patients (pts) recruited in PIONeeR, we focused on the first 137 ≥2nd line ECOG PS0-1 pts treated with single-agent nivolumab, pembrolizumab or atezolizumab. Tumor tissue was collected at baseline and pts were re-biopsied at 6 weeks, and blood-sampled every cycle throughout the 24 weeks post C1D1. Response to PD1/L1 ICIs was assessed by RECIST 1.1 every 6 weeks. Immune contexture was characterized in tumor & blood of each pt through FACS for circulating immune cell subtypes quantification and endothelial activation, blood soluble factors dosage, dual- & multiplex IHC/digital pathology to quantify immune cells infiltrating the tumor, WES for TMB & ICI plasma dosage, leading to 331 measured biomarkers in addition to routine clinical parameters. Multivariable (MV) logistic regression was used to examine the association of each biomarker (controlled by sex, age, smoking status, histological type & PDL1+ Tumor Cells) with the risk of Early Progression (EP), i.e. within 3.5 months of treatment. Multivariable Cox regression analysis was conducted for association with PFS and OS.
Results: Overall, the 137 pts were mainly male (64%), smokers (92%) and <70yrs (68%). Tumors were mainly non-squamous (79%) with >1% PDL1+ TC in 36% of the cases, and 21% of pts were still on treatment at data cut-off. Archived samples were available for 80% of pts at inclusion and re-biopsy was available in 52.9% of these cases. The median follow up was 19.8 months, 22.5% of pts did not progress at data cut-off while 62% presented EP. Tumor Cytotoxic T-cells density, especially PD1+ were lower in EP (MV OR=0.45, p=0.022); conversely, higher proportions of circulating cytotoxic T-cells and activated T-cells (HLA-DR+) were observed in EP (MV OR=3.8, p<0.001). Among other biomarkers, Tregs (MV OR=0.44, p=0.018), NK cell subsets (MV OR≤0.44, p<0.05), albumin (MV OR=0.4, p<0.01) and PDL1 TC % (MV OR=0.27, p<0.01) were decreased whereas alkaline phosphatase was increased (OR=3, p=0.018). >65% inter-pt variability was observed in plasma exposures for all ICIs, with 8-10% of pts displaying trough levels below the target engagement threshold. Data will be presented through unsupervised clustering algorithms & multi-modal supervised learning methods. Changes after 6 weeks of treatment will be analyzed to further investigate drugs mechanisms of action.
Conclusion: The PIONeeR trial provides with the 1st comprehensive biomarkers’ analysis to establish predictive models of resistance in advanced NSCLC pts treated with PD1/L1 ICIs and highlights how tumor and circulating biomarkers are complementary.

Five-year survival outcomes with nivolumab (NIVO) plus ipilimumab (IPI) versus chemotherapy (chemo) as first-line (1L) treatment for metastatic non–small cell lung cancer (NSCLC): Results from CheckMate 227. J Clin Oncol 2022.

Abstract
LBA9025 Background: In CheckMate 227 part 1 (NCT02477826), 1L NIVO + IPI demonstrated long-term, durable survival benefit vs platinum-doublet chemo in patients (pts) with metastatic NSCLC regardless of tumor programmed death ligand 1 (PD-L1) expression level. Here we present the longest reported follow-up (5 y) of a phase 3 trial of 1L combination immunotherapy in metastatic NSCLC. Methods: Adults with previously untreated stage IV or recurrent NSCLC, no known EGFR/ ALK alterations , and an ECOG performance status ≤ 1 were enrolled and stratified by histology. Pts with tumor PD-L1 ≥ 1% were randomized 1:1:1 to NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W), NIVO (240 mg Q2W), or chemo. Pts with tumor PD-L1 < 1% were randomized 1:1:1 to NIVO + IPI, NIVO (360 mg Q3W) + chemo, or chemo. Pts were treated until progression, toxicity, or ≤ 2 y for immunotherapy. Assessments included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), duration of response (DOR), and a novel efficacy endpoint, treatment-free interval. Treatment-free interval was measured in pts who discontinued study therapy (for any reason including treatment completion) and was defined as the time from last study dose to start of subsequent systemic therapy or death, whichever occurred first. Results: Minimum follow-up was 61.3 mo (database lock, Feb 15, 2022). In pts with tumor PD-L1 ≥ 1% (N = 1189), continued long-term OS benefit was seen with NIVO + IPI vs chemo (HR, 0.77 [95% CI, 0.66–0.91]); 5-y OS rates were 24% (NIVO + IPI), 17% (NIVO), and 14% (chemo). OS benefit also continued in pts with tumor PD-L1 < 1% (N = 550) for NIVO + IPI vs chemo (HR, 0.65 [95% CI, 0.52–0.81]); 5-y OS rates were 19% (NIVO + IPI), 10% (NIVO + chemo), and 7% (chemo). Clinical benefit with NIVO + IPI vs chemo was observed across additional efficacy endpoints in the overall population and in pts alive at 5 y (table). PFS, ORR, and DOR with NIVO and NIVO + chemo will be presented. Among pts alive at 5 y in the NIVO + IPI group, 66% (PD-L1 ≥ 1%) and 64% (PD-L1 < 1%) remained treatment-free ≥ 3 y after discontinuing study therapy; median (range) duration of NIVO ± IPI therapy was 17.7 (0-25.5) mo (PD-L1 ≥ 1%) and 9.5 (0-25.1) mo (PD-L1 < 1%). No new safety signals were observed. Conclusions: With a 5-y minimum follow-up, NIVO + IPI continues to provide long-term, durable clinical benefit vs chemo in previously untreated pts with metastatic NSCLC, regardless of PD-L1 expression. NIVO + IPI led to increased 5-y survivorship; the majority of these pts were treatment-free for ≥ 3 y post-treatment discontinuation. Clinical trial information: NCT02477826. [Table: see text]

Abstract
9011 Background: Combination of anti-PD1 and CTLA4 have showed superiority to chemotherapy (CT) in advanced non–small cell lung cancer (NSCLC), but data for fit elderly or PS2 patients are scarce. Methods: eNErgy compared the combination of nivolumab ipilimumab (N-I) to a platinum doublet in elderly or PS2 patients with advanced NSCLC. Primary endpoint was overall survival (OS), secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Main inclusion criteria were: stage IV histologically proven NSCLC, age ≥ 70 y, and PS 0/1/2 or age < 70 and PS2, EGFR ALK/ROS1 negative, judged fit enough to receive a platinum doublet. The main exclusion criteria were active cerebral metastasis or contraindication to N-I. Patients were randomly selected 1/1, stratified by age (≥ 70 vs. < 70 y), PS (0/1 vs. 2), and histology (squamous vs. no-squamous). Nivolumab (240 mg, 2w), ipilimumab, 1 mg/kg, 6w, was administrated until progression or unacceptable toxicity. CT was planned for 4 cycles, with carboplatin (AUC5) and pemetrexed (500 mg/m2, 3w) or paclitaxel (90 mg/m2, d1,d8, d15); 242 patients had to be randomized to detect a treatment effect hazard ratio (HR) on OS of 0.65, with a 85% power at a 2-sided alpha level of 5%. Results: A preplanned interim analysis carried out after observation of 33% of deaths, out of 174 randomized patients, showed a risk of futility especially for PS 2 patients, HR: 1.8 (95% CI, 0.99-3.3). This led to a halt in randomization but continued follow-up of the 204 patients randomized at the time of the decision. The current final analysis is carried out 18 months after the inclusion of the last patient: men, 71%, median age 74 (51-89, PS 0/1/2 in 30%, 37.5%, and 36.6% respectively), smokers or former smokers in 25.5 and 64.4%, with 62% adenocarcinoma. The median OS of N-I and chemo arms were 14.7 (95% CI, 8.0-19.7) and 9.9 (95% CI, 7.7-12.3) months, HR 0.85, 95% CI, 0.62-1.16. The subgroup analyses showed a significant benefit of the association N-I compared to CT for elderly PS 0/1 patients, with median OS of 22.6 (95% CI, 18.1-36) vs. 11.8 (95% CI, 8.9-20.5) months, p = 0.02. In PS2 patients, median OS of N-I and CT arms was 2.9 (1.4-4.8) vs. 6.1 (3.5-10.4) months (p = 0.22). Median PFS was significantly in favor of N-I arm in the entire population: 5.5 (2.8-8.7) vs. 4.6 (3.5-5.6); p = 0.015. Safety was similar with 31.4% of patients with grade ≥ 3 related SAES in N-I arm vs. 49.5% for CT. Treatment was discontinued for toxicity in 28.6% in N-I arm vs. 22.3% of patients in CT arm. Conclusions: Despite no statistically significant benefit in OS observed in the entire population, there was a clinical signal of efficacy of N-I combination over platinum doublet in elderly NSCLC patients PS 0-1 with a significant benefit of OS of 22.6 months vs. 11.8 for CT arm. Clinical trial information: NCT03351361.

Detection of acquired TERT amplification in addition to predisposing p53 and Rb pathways alterations in EGFR-mutant lung adenocarcinomas transformed into small-cell lung cancers. Lung Cancer 2022; 167:98-106. [PMID: 35183375 DOI: 10.1016/j.lungcan.2022.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 01/04/2022] [Accepted: 01/13/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Among the different mechanisms of acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) reported in EGFR-mutated lung adenocarcinoma (EGFR-LUAD) patients, histological transformation into small cell carcinoma (SCLC) occurs in 3-14% of resistant cases, regardless of the generation of EGFR-TKI. In recent studies, bi-allelic inactivation of TP53 and RB1 has been identified in a vast majority of transformed SCLCs. However, the molecular mechanisms driving this histologic transformation remain largely unknown, mainly due to the rarity of samples. PATIENTS AND METHODS Out of an initial cohort of 64 patients, tumor tissues of adequate quality and quantity for whole exome sequencing (WES) analysis were available for nine tumors for six patients: paired pre- and post-SCLC transformation samples for three Patients and post-SCLC transformation samples for three other patients. RESULTS Mutational analyses showed concurrent TP53 mutations and Rb pathway alterations in five of the six patients analyzed, confirming their suggested role as predisposing genetic alterations to SCLC transformation. In addition, TERT amplification was detected in four of the six patients and found to be an event acquired during SCLC transformation. Clonal history evolution analyses from the paired LUAD/SCLC samples showed different evolution patterns. In two patients, a large proportion of mutations were present in the most recent common ancestor cell of the initial LUAD and the transformed SCLC clones, whereas in the third patient, few clonal mutations were common between the LUAD and SCLC samples and the ancestor clone that lead to SCLC was present at low frequency in the initial LUAD. CONCLUSION Despite varied clinical presentations and clonal history evolution patterns, in addition to p53 and Rb pathways alterations, TERT amplification emerged as another common genetic mechanism of EGFR-LUAD to SCLC transformation in our cohort, and could represent a candidate therapeutic target in this subset of SCLC tumors.

Abstract
Aside from PD-L1 expression, biomarkers of response to immune checkpoint inhibitors (ICIs) in non-small-cell lung cancer (NSCLC) are needed. In a previous retrospective analysis, we documented that fecal Akkermansia muciniphila (Akk) was associated with clinical benefit of ICI in patients with NSCLC or kidney cancer. In the current study, we performed shotgun-metagenomics-based microbiome profiling in a large cohort of patients with advanced NSCLC (n = 338) treated with first- or second-line ICIs to prospectively validate the predictive value of fecal Akk. Baseline stool Akk was associated with increased objective response rates and overall survival in multivariate analyses, independent of PD-L1 expression, antibiotics, and performance status. Intestinal Akk was accompanied by a richer commensalism, including Eubacterium hallii and Bifidobacterium adolescentis, and a more inflamed tumor microenvironment in a subset of patients. However, antibiotic use (20% of cases) coincided with a relative dominance of Akk above 4.8% accompanied with the genus Clostridium, both associated with resistance to ICI. Our study shows significant differences in relative abundance of Akk that may represent potential biomarkers to refine patient stratification in future studies.

Third dose of anti-SARS-CoV-2 vaccine for patients with cancer: Should humoral responses be monitored? A position article. Eur J Cancer 2022; 162:182-193.

Abstract
Taking into account higher risk of severe coronavirus disease 2019 or death among patients with cancer, as well as impaired immunogenicity after anti-SARS-CoV-2 vaccines, in addition to waning immunity, booster dosing appears mandatory in this patient population. This review sought to provide reasonable evidence so as to assist oncologists in their daily practice, helping them decide when an anti-SARS-Cov2 antibody (Ab) dosage should be scheduled after a full two-dose vaccination and, if necessary, propose an early third dose (D3). Such D3 could apply to non-responder patients with anti-Spike (S) Abs titres <40 binding Ab unit (BAU)/mL. For lowresponder patients with anti-S Ab titres between 40 BAU/mL and 100/260 BAU/mL (suggested area of uncertainty), an early D3 may similarly be proposed. Nevertheless, this D3 could be administered in a less urgent manner, taking into account associated comorbidities and regional epidemic incidence rates. This latter strategy may comprise a monthly dosage of anti-S titres so as to better assess the kinetics of waning immunity. For responder patients with anti-S titres above 260 BAU/mL, we suggest to follow the recommendations outlined for the general population. Given this context, patients with anti-S titres above 1000 BAU/mL should be given the possibility to undergo anti-S titre control after three months, designed to assess rapid humoral waning immunity. We strongly recommend that patients with cancer be included into observational serological monitoring studies or clinical trials that are dedicated to severe immunocompromised patients without any humoral seroconversion after D3.

Abstract
BACKGROUND Immunotherapy using inhibitors targeting immune checkpoint programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) is currently the standard of care in patients with advanced non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS We carried out a nationwide cohort retrospective study of consecutive patients with advanced, refractory NSCLC who received nivolumab as second to later lines of treatment as part of the expanded access program. Key objectives were to assess the efficacy and safety of nivolumab and the efficacy of first post-nivolumab treatment. RESULTS Nine hundred and two patients were enrolled: 317 (35%) with squamous cell carcinoma and 585 (65%) with non-squamous cell carcinoma. Median age was 64 years; there were 630 (70%) men, 795 (88%) smokers, 723 (81%) patients with an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0/1, 197 (22%) patients with brain metastases, and 212 (27%) with liver metastases. Best response was partial response for 16.2% and stable disease (SD) for 30.5%. Progression-free survival and overall survival (OS) rates at 2, 3, and 5 years were 8% and 25%, 6% and 16%, and 4% and 10%, respectively. At multivariate analysis, ECOG PS ≥2 [hazard ratio (HR) = 2.13, 95% confidence interval (95% CI) 1.78-2.55, P < 0.001], squamous histology (HR = 1.17, 95% CI 1.01-1.36, P = 0.04), and presence of central nervous system metastases (HR = 1.29, 95% CI 1.08-1.54, P = 0.005) were significantly associated with lower OS. Four hundred and ninety-two patients received at least one treatment after discontinuation of nivolumab, consisting of systemic therapies in 450 (91%). Radiation therapy was delivered to 118 (24%) patients. CONCLUSION The CLINIVO cohort represents the largest real-world evidence cohort with the use of immune checkpoint inhibitor in advanced, metastatic NSCLC after failure of first-line chemotherapy, with long-term follow-up and analysis of subsequent therapies. Our data confirm the efficacy of nivolumab in a cohort larger than that reported in landmark clinical trials and identify prognostic factors, which reinforces the need for accurate selection of patients for treatment with immune checkpoint inhibitors. Our data indicate that oligoprogression is frequent after nivolumab exposure and provide a unique insight into the long-term survival.

Abstract
BACKGROUND Benefit from maintenance in advanced non-squamous non-small cell lung cancer (NS-NSCLC) might favor switch maintenance after disease stabilization (SD) and continuation after objective response (OR). This trial assessed a maintenance strategy conditioned by response to cisplatin-gemcitabine (CG) with G continuation for patients with OR or switch to pemetrexed (P) for patients with SD as compared with a control arm based on the Paramount regimen. METHODS Eligibility criteria: age 18-70 years, ECOG PS 0-1, untreated stage IV NS-NSCLC without EGFR or ALK alteration, ineligibility to bevacizumab. Patients were randomized 1:1 to receive either CG (4 cycles) followed by G maintenance in case of OR followed by P at progression, or switch to P for patients with SD, or 4 cycles of CP followed by P (control arm). Primary endpoint: overall Survival. RESULTS Between 2012 and 2016, 932 patients were randomized (CG: 467, CP: 465) with well-balanced characteristics. 257 patients (56.7%) in the CG arm received maintenance (G: 142, P: 113) versus 277 patients (59.7%) in the CP arm. Median number of maintenance cycles was 5 for G and P (CG induction) and 4 for P (CP induction). OS adjusted HR was 0.97 (95% CI 0.84, 1.13; p = 0.71) with a median of 10.9 months (CG) versus 10.4 (CP). HR for PFS was 0.95 (95% CI 0.83, 1.09; p = 0.45) with a median of 4.8 months for CG versus 4.5 for CP. Safety profile was as expected. CONCLUSIONS Adapting maintenance strategy according to response to induction chemotherapy does not improve patient outcome. CLINICAL TRIAL INFORMATION NCT01631136.

First-Line Nivolumab Plus Ipilimumab in Advanced NSCLC: 4-Year Outcomes From the Randomized, Open-Label, Phase 3 CheckMate 227 Part 1 Trial. J Thorac Oncol 2021; 17:289-308. [PMID: 34648948 DOI: 10.1016/j.jtho.2021.09.010] [Citation(s) in RCA: 143] [Impact Index Per Article: 47.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 09/07/2021] [Accepted: 09/20/2021] [Indexed: 12/25/2022]
Abstract
INTRODUCTION In CheckMate 227, nivolumab plus ipilimumab prolonged overall survival (OS) versus chemotherapy in patients with tumor programmed death-ligand 1 (PD-L1) greater than or equal to 1% (primary end point) or less than 1% (prespecified descriptive analysis). We report results with minimum 4 years' follow-up. METHODS Adults with previously untreated stage IV or recurrent NSCLC were randomized (1:1:1) to nivolumab plus ipilimumab, nivolumab, or chemotherapy (PD-L1 ≥1%); or to nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy (PD-L1 <1%). Efficacy included OS and other measures. Safety included timing and management of immune-mediated adverse events (AEs). A post hoc analysis evaluated efficacy in patients who discontinued nivolumab plus ipilimumab due to treatment-related AEs (TRAEs). RESULTS After 54.8 months' median follow-up, OS remained longer with nivolumab plus ipilimumab versus chemotherapy in patients with PD-L1 greater than or equal to 1% (hazard ratio = 0.76; 95% confidence interval: 0.65-0.90) and PD-L1 less than 1% (0.64; 0.51-0.81); 4-year OS rate with nivolumab plus ipilimumab versus chemotherapy was 29% versus 18% (PD-L1 ≥1%); and 24% versus 10% (PD-L1 <1%). Benefits were observed in both squamous and nonsquamous histologies. In a descriptive analysis, efficacy was improved with nivolumab plus ipilimumab relative to nivolumab (PD-L1 ≥1%) and nivolumab plus chemotherapy (PD-L1 <1%). Safety was consistent with previous reports. The most common immune-mediated AE with nivolumab plus ipilimumab, nivolumab, and nivolumab plus chemotherapy was rash; most immune-mediated AEs (except endocrine events) occurred within 6 months from start of treatment and resolved within 3 months after, mainly with systemic corticosteroids. Patients who discontinued nivolumab plus ipilimumab due to TRAEs had long-term OS benefits, as seen in the all randomized population. CONCLUSIONS At more than 4 years' minimum follow-up, with all patients off immunotherapy treatment for at least 2 years, first-line nivolumab plus ipilimumab continued to demonstrate durable long-term efficacy in patients with advanced NSCLC. No new safety signals were identified. Immune-mediated AEs occurred early and resolved quickly with guideline-based management. Discontinuation of nivolumab plus ipilimumab due to TRAEs did not have a negative impact on the long-term benefits seen in all randomized patients.

Abstract
9095 Background: Targeted therapies (TT) are approved in NSCLC based on a limited number of oncogenic drivers. Numerous additional TT can be matched to other molecular alterations found in comprehensive profiles. We investigated the effect of 8 TT compared to SoC as a maintenance strategy after chemotherapy in pts with metastatic NSCLC. Methods: In SAFIR02-LUNG trial (NCT: 02117167), open-label multicentric phase II randomized trials, PS 0-1 pts with ALK/EGFR WT NSCLC after a CR/PR/SD to 4 cycles of platinum-based chemotherapy were selected. All pts underwent a fresh biopsy, followed by targeted sequencing on 70 genes and SNP-array when > 30% cancer cells were present on HES slides. In case of genomic alteration (including KRAS, ERBB2, BRAF, BRCA mutations), pts were randomized 2:1 between 8 TT and SoC. TT allocation was decided during weekly national tumor board, based on predefined guidelines. The primary endpoint was Progression-Free Survival (PFS) and the secondary endpoint was Overall Survival (OS). Results: 999 patients were enrolled and 394 had a molecular alteration eligible for the study. Among the 175 randomized pts (between July 2014 and May 2019), 116 received TT (65 selumetinib, 18 vistusertib, 9 capivasertib, 8 AZD4547, 5 AZD8931, 5 vandetanib, 4 olaparib, 1 savolitinib) and 59 SoC (54 pemetrexed, 4 gemcitabine and 1 erlotinib). Median age was 60, 40.6% were female, 4.6% never-smoker, 44% were PS 0, 88.6% had a non-squamous NSCLC and 26.9% a PR to chemotherapy. At data cut-off, 168 pts had progressed or died. With a median follow-up of 42.0 months (mo), median PFS was 2.7 mo (95% confidence interval (CI) 1.6 to 2.7) with TT vs. 2.7 mo (95%CI 1.6-4.1) with SoC (HR for disease progression or death 1.00; 95%CI = 0.73 to 1.38; p = 0.978). There was no significant PFS differences among the molecular subgroups; in the cohort with KRAS or BRAF mutation without STK11 mutations the HR for disease progression or death was 0.76; 95%CI = 0.52 to 1.13; p = 0.17. Median OS was 14.3 mo (95%CI 11.0-18.3) with TT vs. 14.1 mo (95% CI 8.0-30.9) with SoC (HR for death 1.12; 95%CI = 0.75-1.65; p = 0.581). Grade 3 or 4 treatment-related adverse events occurred in 31 pts (26.7%) on TT (G3: 30 pts (25.9%), G4: 1 pt (0.8%)) and in 13 (22%) on SoC (G3 8 pts, G4 5 pts). Conclusions: The SAFIR02-LUNG trial demonstrated the feasibility of a routine precision medicine for advanced NSCLC. However, the monotherapy TT used as maintenance therapy after platinum-based chemotherapy failed to improve PFS or OS in this advanced ALK/EGFR WT NSCLC pts population. Newly available therapeutic options (ex. for KRASG12C, RET, NTRK, ERBB2, NRG1, etc) need to be evaluated. Clinical trial information: 2013-001653-27.

Abstract
9019 Background: The gut microbiome, most specifically centered on one of the most prevalent anaerobic bacterium Akkermansia muciniphila (Akk), has emerged as a potential hallmark of clinical benefit to ICI. The goal of this study was to validate the prognostic significance of Akk in advanced NSCLC patients amenable to ICI. Methods: The multicentric prospective observational study enrolled patients with advanced NSCLC amenable to single agent ICI in first and second line. Stool sample was collected at study entry. Primary end-point was investigator-assessed objective response rate (ORR). We considered that a meaningful clinical difference would correlate to a 10% ORR increase in the Akk-Pos group compared to the Akk-Neg group. At least 292 patients equally divided each in each group would be required for a power at 80% and a two-sided alpha level of 5%. Results: From Dec 2015 to Nov 2019, a total of 409 patients were screened and 311 patients enrolled across 12 academic centers in France and Canada. Median age was 64yr, 32% were female, 77% had non-squamous NSCLC and PD-L1 was ≥1% in 70% of the 213 assessable samples. Akk was detectable in 158 (51%) and absent in 153 (49%) patients. Baseline characteristics were well balanced between the two groups. When considering Akk-Pos vs Akk-Neg groups the primary endpoint ORR was 27% and 17% respectively ( p = 0.04). Rates of partial response, stable disease and progressive disease (PD) were 62%, 50% and 46% respectively in the Akk-Pos group compared to 38%, 50% and 54% in the Akk-Neg group ( p = 0.04). Moreover, 57% of patients were still alive after 12 months in the Akk-Pos group vs 43% in the Akk-Neg group ( p = 0.04). Microbiome profiling demonstrated that Akk-Pos group was associated with increase bacterial diversity and enrichment of Ruminococcus, Alistipes and Eubacterium. When considering the variations of the relative abundance of Akk within the Akk-Pos group, we obtained a large interval ranging from 0.0022% up to 64.78% with a 75th percentile at 4.42%. The relative abundance of Akk within > 0% to < 4.42% range in stools at diagnosis was associated with increased ORR, overall survival (OS) in multivariate analysis, independent of PD-L1 expression and ECOG. This sub-group was associated with more inflamed tumors with upregulation of CD3e, IfngTH1 and Vcam-1. Conversely, patients with overrepresentation of Akk > 4.42% experienced more PD and shorter OS. Antibiotic use was associated with a shift in favor of Gammaproteobacteria, enrichment of Akk ( > 4.42%) and shorter OS. Conclusions: We validated the prognostic role of Akk in patients with NSCLC. Stratification based on Akk relative abundance represents a more accurate independent predictor than the binary modality. Our study provides the rationale to develop microbiome-based approach to study gut dysbiosis in routine clinical oncology care. Clinical trial information: NCT04567446.

Predicting immunotherapy outcomes under therapy in patients with advanced NSCLC using dNLR and its early dynamics. Eur J Cancer 2021; 151:211-220. [PMID: 34022698 DOI: 10.1016/j.ejca.2021.03.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/16/2021] [Accepted: 03/01/2021] [Indexed: 01/17/2023]
Abstract
BACKGROUND dNLR at the baseline (B), defined by neutrophils/[leucocytes-neutrophils], correlates with immune-checkpoint inhibitor (ICI) outcomes in advanced non-small-cell lung cancer (aNSCLC). However, dNLR is dynamic under therapy and its longitudinal assessment may provide data predicting efficacy. We sought to examine the impact of dNLR dynamics on ICI efficacy and understand its biological significance. PATIENTS AND METHODS aNSCLC patients receiving ICI at 17 EU/US centres were included [Feb/13-Jun/18]. As chemotherapy-only group was evaluated (NCT02105168). dNLR was determined at (B) and at cycle2 (C2) [dNLR≤3 = low]. B+C2 dNLR were combined in one score: good = low (B+C2), poor = high (B+C2), intermediate = other situations. In 57 patients, we prospectively explored the immunophenotype of circulating neutrophils, particularly the CD15+CD244-CD16lowcells (immature) by flow cytometry. RESULTS About 1485 patients treatment with ICI were analysed. In ICI-treated patients, high dNLR (B) (~1/3rd) associated with worse progression-free (PFS)/overall survival (OS) (HR 1.56/HR 2.02, P < 0.0001) but not with chemotherapy alone (N = 173). High dNLR at C2 was associated with worse PFS/OS (HR 1.64/HR 2.15, P < 0.0001). When dNLR at both time points were considered together, those with persistently high dNLR (23%) had poor survival (mOS = 5 months (mo)), compared with high dNLR at one time point (22%; mOS = 9.2mo) and persistently low dNLR (55%; mOS = 18.6mo) (P < 0.0001). The dNLR impact remained significant after PD-L1 adjustment. By cytometry, high rate of immature neutrophils (B) (30/57) correlated with poor PFS/OS (P = 0.04; P = 0.0007), with a 12-week death rate of 49%. CONCLUSION The dNLR (B) and its dynamics (C2) under ICI associate with ICI outcomes in aNSCLC. Persistently high dNLR (B+C2) correlated with early ICI failure. Immature neutrophils may be a key subpopulation on ICI resistance.

Circulating tumor DNA in advanced non-small-cell lung cancer patients with HIV is associated with shorter overall survival: Results from a Phase II trial (IFCT-1001 CHIVA). Lung Cancer 2021; 157:124-130. [PMID: 34016488 DOI: 10.1016/j.lungcan.2021.05.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 04/27/2021] [Accepted: 05/09/2021] [Indexed: 12/22/2022]
Abstract
INTRODUCTION HIV is an exclusion criterion for most lung cancer (LC) trials, however LC is the most common non-AIDS-defined malignancy in people living with HIV (PLHIV), poorer prognosis than the general population. Circulating tumor DNA (ctDNA) was a prognostic marker in LC patients from the general population. This study assessed ctDNA's prognostic value in PLHIV from a dedicated phase II trial. METHODS Overall, 61 PLHIV with advanced non-squamous non-small-cell lung cancer (NSCLC) participated in the IFCT Phase II trial evaluating first-line four-cycle carboplatin (Ca) AUC5 pemetrexed (P) 500 mg/m2 induction therapy every 3 weeks, followed by P maintenance therapy. Blood samples collected before treatment were analyzed to detect ctDNA using ultra-deep targeted next-generation-sequencing (NGS). RESULTS Appropriate samples were available from 55 PLVIH and analyzed for ctDNA detection. Including 42 males (76.4 %), 52.9 years median age, 51 smokers (92.7 %), five with non-squamous NSCLC Stage III (9%), 50 Stage IV (91 %), and performance status (PS) 0-2. ctDNA was detected in 35 patients (64 %), 22 with high and 13 with low ctDNA levels. Overall, 77 % were positive for TP53, 29 % for KRAS, and 11 % for STK11 mutations, more than one alteration was detected in 43 % of samples. Multivariate analysis showed that positive ctDNA was significantly associated with shorter PFS (HR, 4.31, 95 %CI: 2.06-8.99, p < 0.0001), and shorter OS (HR, 3.52, 95 %CI: 1.72-7.19, p < 0.001). Moreover, OS was significantly longer for patients with low ctDNA levels at diagnosis as compared to high (p = 0.01). CONCLUSION We show that ctDNA detection using ultra-deep NGS is an independent prognostic factor in PLHIV with advanced NSCLC.

Two-year survival with nivolumab in previously treated advanced non-small-cell lung cancer: A real-world pooled analysis of patients from France, Germany, and Canada. Lung Cancer 2021; 157:40-47. [PMID: 33980420 DOI: 10.1016/j.lungcan.2021.04.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 04/23/2021] [Accepted: 04/25/2021] [Indexed: 11/25/2022]
Abstract
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.

Abstract
BACKGROUND Patients with relapsed small-cell lung cancer (SCLC) have few treatment options and dismal survival. Phase I/II data show activity of nivolumab in previously treated SCLC. PATIENTS AND METHODS CheckMate 331 is a randomized, open-label, phase III trial of nivolumab versus standard chemotherapy in relapsed SCLC. Patients with relapse after first-line, platinum-based chemotherapy were randomized 1 : 1 to nivolumab 240 mg every 2 weeks or chemotherapy (topotecan or amrubicin) until progression or unacceptable toxicity. Primary endpoint was overall survival (OS). RESULTS Overall, 284 patients were randomized to nivolumab and 285 to chemotherapy. Minimum follow-up was 15.8 months. No significant improvement in OS was seen with nivolumab versus chemotherapy [median OS, 7.5 versus 8.4 months; hazard ratio (HR), 0.86; 95% confidence interval (CI), 0.72-1.04; P = 0.11]. A survival benefit with nivolumab was suggested in patients with baseline lactate dehydrogenase ≤ upper limit of normal and in those without baseline liver metastases. OS (nivolumab versus chemotherapy) was similar in patients with programmed death-ligand 1 combined positive score ≥1% versus <1%. Median progression-free survival was 1.4 versus 3.8 months (HR, 1.41; 95% CI, 1.18-1.69). Objective response rate was 13.7% versus 16.5% (odds ratio, 0.80; 95% CI, 0.50-1.27); median duration of response was 8.3 versus 4.5 months. Rates of grade 3 or 4 treatment-related adverse events were 13.8% versus 73.2%. CONCLUSION Nivolumab did not improve survival versus chemotherapy in relapsed SCLC. No new safety signals were seen. In exploratory analyses, select baseline characteristics were associated with improved OS for nivolumab.

Abstract
INTRODUCTION In CheckMate 227 (NCT02477826), patients with treatment-naive stage IV or recurrent NSCLC and 1% or greater tumor programmed death ligand 1 expression had significantly improved overall survival with nivolumab plus ipilimumab versus chemotherapy. We present the patient-reported outcomes (PROs). METHODS Patients (N = 1189) were randomized to nivolumab plus ipilimumab, nivolumab, or chemotherapy. PROs were exploratory. Changes in Lung Cancer Symptom Scale (LCSS) average symptom burden index, LCSS 3-item global index, EQ-5D visual analog scale (VAS), and EQ-5D utility index were analyzed descriptively. Mixed-effect model repeated measures and time-to-first deterioration and improvement analyses were conducted. RESULTS PRO completion rates were generally greater than 80%. On-treatment improvements from baseline in LCSS measures of symptom burden and global health status with nivolumab plus ipilimumab generally met or exceeded the minimal important difference (smallest clinically meaningful change) from weeks 24 and 30, respectively; improvements with chemotherapy generally remained below the minimal important difference. Mean on-treatment EQ-5D VAS scores for both treatments approached the U.K. population norm at week 24, remaining so throughout the treatment period. Mixed-effect model repeated measures analyses revealed numerically greater improvements from baseline with nivolumab plus ipilimumab versus chemotherapy across LCSS average symptom burden index and 3-item global index, and EQ-5D VAS and utility index. Nivolumab plus ipilimumab had delayed time-to-first deterioration (hazard ratio [95% confidence interval] 0.74 [0.56 to 0.98]) and a trend for more rapid time-to-first improvement (1.24 [0.98 to 1.59]) versus chemotherapy. CONCLUSIONS Nivolumab plus ipilimumab revealed delayed deterioration and numerical improvement in symptoms and health-related quality of life versus chemotherapy in patients with advanced NSCLC and 1% or greater programmed death ligand 1 expression.

Circulating Tumor DNA as a Prognostic Determinant in Small Cell Lung Cancer Patients Receiving Atezolizumab. J Clin Med 2020; 9:E3861.

Abstract
BACKGROUND The IFCT-1603 trial evaluated atezolizumab in small cell lung cancer (SCLC). The purpose of the present study was to determine whether circulating tumor DNA (ctDNA), prospectively collected at treatment initiation, was associated with the prognosis of SCLC, and whether it identified patients who benefited from atezolizumab. METHODS 68 patients were included in this study: 46 patients were treated with atezolizumab and 22 with conventional chemotherapy. Circulating DNA was extracted from plasma and NGS (Next Generation Sequencing) looked for mutations in the TP53, RB1, NOTCH1, NOTCH2, and NOTCH3 genes. ctDNA was detectable when at least one somatic mutation was identified, and its relative abundance was quantified by the variant allele fraction (VAF) of the most represented mutation. RESULTS We found that 49/68 patients (70.6%) had detectable baseline ctDNA. The most frequently identified mutations were TP53 (32/49; 65.3%) and RB1 (25/49; 51.0%). Patients with detectable ctDNA had a significantly lower disease control rate at week 6 compared with patients with no detectable ctDNA, regardless of the nature of the treatment. Detection of ctDNA was associated with a poor OS prognosis. The detection of ctDNA at a relative abundance greater than the median value was significantly associated with poor overall survival (OS) and progression free survival (PFS). Interestingly, the benefit in overall survival (OS) associated with low ctDNA was more pronounced in patients treated with atezolizumab than in patients receiving chemotherapy. Among patients whose relative ctDNA abundance was below the median, those treated with atezolizumab tended to have higher OS than those in the chemotherapy arm. CONCLUSION ctDNA is strongly associated with the prognosis of SCLC patients treated with second-line immunotherapy. Its analysis seems justified for future SCLC clinical trials.

PTEN, ATM, IDH1 mutations and MAPK pathway activation as modulators of PFS and OS in patients treated by first line EGFR TKI, an ancillary study of the French Cooperative Thoracic Intergroup (IFCT) Biomarkers France project. Lung Cancer 2020; 151:69-75. [PMID: 33248711 DOI: 10.1016/j.lungcan.2020.11.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 10/22/2020] [Accepted: 11/10/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Tumor mutation screening is standard of care for patients with stage IV NSCLC. Since a couple of years, widespread NGS approaches used in routine diagnostics to detect driver mutations such as EGFR, KRAS, BRAF or MET allows the identification of other alterations that could modulated the intensity or duration of response to targeted therapies. The prevalence of co-occurring alterations that could affect response or prognosis as not been largely analyzed in clinical settings and large cohorts of patients. Thanks to the IFCT program "Biomarkers France", a collection of samples and data at a nation-wide level was available to test the impact of co-mutations on first line EGFR TKI in patients with EGFR mutated cancers. MATERIALS AND METHODS Targeted NGS was assessed on available (n = 208) samples using the Ion AmpliSeq™ Cancer Hotspot Panel v2 to screen for mutations in 50 different cancer genes. RESULTS This study showed that PTEN inactivating mutations, ATM alterations, IDH1 mutations and complex EGFR mutations were predictors of short PFS in patients with a stage 4 lung adenocarcinoma receiving first line EGFR TKI and that PTEN, ATM, IDH1 and KRAS mutations as well as alterations in the MAPK pathway were related to shorter OS. CONCLUSION These findings may lead to new treatment options in patients with unfavorable genotypes to optimize first line responses.

Abstract
PURPOSE Hyperprogressive disease (HPD), fast progression (FP), and early death (ED) have been described in 13.8%, 4.7%, and 5.6% and in 5.1%, 2.8%, and 6.8%, respectively, of patients with non–small-cell lung cancer (NSCLC) treated with single-agent programmed cell death ligand 1 inhibitors (ICI) or chemotherapy, respectively. Whether FP/ED and HPD represent overlapping patterns is unknown. PATIENTS AND METHODS FP, ED, and HPD were retrospectively assessed in patients with NSCLC treated with single-agent ICI or chemotherapy. Eligibility required 2 computed tomography (CT) scans before and 1 CT scan during treatment. (1) HPD, (2) FP, (3) ED were defined as (1) RECIST version 1.1 progression at first CT scan and tumor growth rate variation per month > 50%, (2) ≥ 50% increase in the sum of the longest diameters of target lesions within 6 weeks from baseline, and (3) death as a result of radiologic progression within 12 weeks from baseline CT scan, respectively. RESULTS Of 406 ICI-treated NSCLC, 56 patients (13.8%), 9 patients (2.2%), and 36 patients (8.8%) were HPD, FP, and ED, respectively. Eight (14.2%) and 20 (35.7%) of 56 patients with HPD were also FP and ED. ED significantly correlated with baseline Eastern Cooperative Oncology Group performance status ≥ 2 compared with HPD (33% v 13%, P = .02). Overall survival was significantly longer for HPD (3.4 months [95% CI, 2.7 to 4.0 months]) compared with FP (0.7 months [95% CI, 0.6 to 0.8 months]); HR, 0.18 [95% CI, 0.08 to 0.42]; P < .0001) and ED (1.4 months [95% CI, 1.3 to 1.6 months]); HR, 0.19 [95% CI, 0.11 to 0.34]); P < .0001), whereas it did not differ between FP and ED (HR, 1.3 [95% CI, 0.56 to 3.0]; P = .55). Of 59 patients with NSCLC treated with single-agent chemotherapy, the HPD, FP, and ED rates were 5.1%, 1.7%, and 6.7%, respectively. CONCLUSION FP, ED, and HPD represent distinct progression patterns with limited overlap and different survival outcomes.

Switch maintenance chemotherapy versus observation after carboplatin and weekly paclitaxel doublet chemotherapy in elderly patients with advanced non-small cell lung cancer: IFCT-1201 MODEL trial. Eur J Cancer 2020; 138:193-201. [PMID: 32898792 DOI: 10.1016/j.ejca.2020.07.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/28/2020] [Accepted: 07/31/2020] [Indexed: 11/20/2022]
Abstract
PURPOSE Maintenance chemotherapy is a reasonable choice for patients with metastatic non-small cell lung carcinoma (NSCLC) not progressing after induction therapy with a platinum-based doublet. Nevertheless, there have been no studies dedicated to elderly patients. PATIENTS AND METHODS We conducted a randomised trial in patients aged 70-89 years, with advanced NSCLC (with neither EGFR mutation nor ALK rearrangement), who had not progressed after four cycles of monthly carboplatin and weekly paclitaxel in order to compare maintenance with either pemetrexed (500 mg/m2 d1, 22) in patients with non-squamous cell carcinoma or gemcitabine (1,150 mg/m2 d1, 8, 22) in squamous cell carcinoma to simple observation. The patients were required to have a performance status (PS) 0-2, mini-mental score >23, and creatinine clearance ≥45 mL/min. The primary end-point was overall survival (OS). RESULTS 632 patients were enrolled from May 2013 to October 2016. Of the 328 (52.3%) patients randomised after induction therapy, 166 patients were assigned to the observation arm, versus 162 to the switch maintenance arm, 119 of whom received pemetrexed and 43 gemcitabine. The median OS from randomisation was 14.1 months (95% confidence interval [CI]: 12.0-17.0) in the observation arm and 14 months (95% CI: 10.9-16.9) in the maintenance arm (p = 0.72). The median progression-free survival (PFS) from randomisation was 2.7 months (95% CI: 2.6-3.1) in the observation arm versus 5.7 months (95% CI: 4.8-7.1) in the maintenance arm (p < 0.001). CONCLUSION Switch maintenance therapy significantly prolonged PFS but not OS and, thus, should not be proposed to elderly patients with advanced NSCLC.

Abstract
HIV infection is an exclusion criterion in lung cancer trials. This multicentre phase II trial aimed to assess feasibility, efficacy and safety of first-line carboplatin plus pemetrexed (CaP) followed by pemetrexed (P) maintenance in people living with HIV (PLHIV) with advanced non-squamous non-small cell lung cancer (NS-NSCLC).Four cycles of CaP were followed by P-maintenance therapy in patients with Eastern Cooperative Oncology Group performance status ≤2. The primary objective was a disease control rate (DCR) ≥30% after 12 weeks.Of the 61 PLHIV enrolled, 49 (80%) had a performance status of 0-1, and 19 (31%) had brain metastases. Median CD4 lymphocyte count was 418 cells·µL-1 (range 18-1230), median CD4 lymphocyte nadir was 169.5 cells·µL-1 (1-822); 48 (80%) patients were virologically controlled. Four-cycle inductions were achieved by 38 (62%) patients, and 31 (51%) started P-maintenance (median of 4.1 cycles (range 1-19)). The 12-week DCR was 50.8% (95% CI 38.3-63.4) and partial response rate 21.3%. Median progression-free survival and overall survival were 3.5 (95% CI 2.7-4.4) and 7.6 months (5.7-12.8), respectively. Patients with a performance status of 0-1 had the longest median progression-free survival (4.3 months, 95% CI 3.1-5.2) and overall survival (11.9 months, 95% CI 6.4-14.3). During induction, CaP doublet was well tolerated apart from grade 3-4 haematological toxicities (neutropenia 53.8%; thrombocytopenia 35.0%; anaemia 30.0%). Two fatal treatment-related sepses were reported. No opportunistic infections were experienced.In PLHIV with advanced NS-NSCLC, first-line four-cycle CaP induction followed by P-maintenance was effective and reasonably well-tolerated. Further studies should evaluate combination strategies of CaP with immunotherapy in PLHIV.

Somatic and Germline BRCA 1 and 2 Mutations in Advanced NSCLC From the SAFIR02-Lung Trial. JTO Clin Res Rep 2020; 1:100068. [PMID: 34589950 PMCID: PMC8474245 DOI: 10.1016/j.jtocrr.2020.100068] [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: 04/04/2020] [Revised: 05/17/2020] [Accepted: 06/03/2020] [Indexed: 12/19/2022] Open
Abstract
Introduction Molecular profiling is considered a standard of care in advanced NSCLC. A comprehensive next-generation sequencing panel can discover somatic or germline BRCA1/2 mutations that are new druggable molecular alterations. However, the phenotypic and potential therapeutic relevance of BRCA1/2 mutation in NSCLC remains poorly defined. Methods From April 2014 to March 2017, 600 newly diagnosed, EGFR/ALK negative patients with advanced NSCLC were enrolled in the SAFIR02-Lung trial. Molecular profiling was done at study entry on archival tissue or frozen tissue collected from a new biopsy specimen before the third cycle of platinum-based chemotherapy. The prevalence of BRCA1/2 variants and its biological relevance were assessed. A homologous recombinant deficiency (HRD) score was based on the copy number variation data, and the germline status was determined by blood analysis. The BRCA Share database and the French CGG consortium were the references for the variant classification. Results Of 379 patients with a molecular profile discussed in a tumor molecular board, BRCA1/2 variants were identified in 20 patients (5.3%), including eight patients (2.1%) with a confirmed pathogenic BRCA mutation. Two patients (0.5%) harbored a germline BRCA2 mutation, and for six others, a somatic BRCA mutation was identified (1.6%). All were men and mainly smokers (88%). The overall response rate to chemotherapy was 13%. BRCA variants of unknown significance were detected in 12 patients (3.2%), achieving an 8.3% overall response rate with chemotherapy. One-third of tumors carrying pathogenic BRCA mutations or variants of unknown significance had biallelic inactivation and high HRD score. Overall survival of this cohort was 12.8 months. Conclusions Pathogenic BRCA1/2 mutations occur in 2.1% of patients with advanced NSCLC. The predictive role of BRCA mutation for making treatment decisions in NSCLC seems limited based on clinical response (low platinum sensitivity) and molecular features (discrepancy between biallelic inactivation and high HRD score).

Abstract
The objective of this document is to formalize a degraded mode management for patients with thoracic cancers in the context of the COVID-19 pandemic. The proposals are based on those of the French High Council for Public Health, on published data outside the context of COVID-19, and on a concerted analysis of the risk-benefit ratio for our patients by a panel of experts specialized on thoracic oncology under the aegis of the French-Language Society of Pulmonology (SPLF)/French-language oncology group. These proposals are evolving (10 April 2020) according to the situations encountered, which will enrich it, and are to be adapted to our institutional organisations and to the evolution of resources during the COVID-19 epidemic. Patients with symptoms and/or COVID-19+ are not discussed in this document and are managed within the framework of specific channels.

Abstract
9500 Background: In the phase 3 CheckMate 227 Part 1 (NCT02477826; minimum follow-up, 29.3 mo), 1L NIVO + IPI significantly improved overall survival (OS) vs chemo in treatment-naive patients (pts) with aNSCLC and tumor PD-L1 expression ≥ 1% (primary analysis) or < 1% (pre-specified descriptive analysis). Here we report data with 3-y minimum follow-up. Methods: Pts with stage IV / recurrent NSCLC and PD-L1 ≥ 1% (n = 1189) were randomized 1:1:1 to NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W), NIVO (240 mg Q2W) alone, or chemo. Pts with PD-L1 < 1% (n = 550) were randomized to NIVO + IPI, NIVO (360 mg Q3W) + chemo, or chemo. Primary endpoint was OS with NIVO + IPI vs chemo in pts with PD-L1 ≥ 1%. An exploratory analysis of OS in pts by response status (CR/PR, SD, progressive disease [PD]) at 6 mo was conducted. Results: After a median follow-up of 43.1 mo (database lock, 28 Feb 2020), pts with PD-L1 ≥ 1% continued to derive OS benefit from NIVO + IPI vs chemo (HR: 0.79; 95% CI, 0.67–0.93); 3-y OS rates were 33% (NIVO + IPI), 29% (NIVO), and 22% (chemo). At 3 y, 18% of pts with PD-L1 ≥ 1% treated with NIVO + IPI remained progression-free vs 12% with NIVO and 4% with chemo; 38% of confirmed responders remained in response in the NIVO + IPI arm at 3 y vs 32% in the NIVO arm and 4% in the chemo arm. In pts with PD-L1 < 1%, OS HR for NIVO + IPI vs chemo was 0.64 (95% CI, 0.51–0.81); 3-y OS rates were 34% (NIVO + IPI), 20% (NIVO + chemo), and 15% (chemo); 13%, 8%, and 2% of pts remained progression-free; and 34%, 15%, and 0% of confirmed responders remained in response, respectively. Pts with PD-L1 ≥ 1% with either CR/PR at 6 mo had longer subsequent OS with NIVO + IPI vs chemo; pts with SD or PD at 6 mo had generally similar subsequent OS between treatments (Table); results in PD-L1 < 1% pts will be presented. Any-grade / grade 3–4 treatment-related AEs were observed in 77% / 33% of all pts treated with NIVO + IPI, and 82% / 36% with chemo. Conclusions: With 3 y minimum follow-up, NIVO + IPI continued to provide durable and long-term OS benefits vs chemo for pts in 1L aNSCLC. Pts with PD-L1 ≥ 1% who achieved CR/PR at 6 mo had marked OS benefit with NIVO + IPI vs chemo. No new safety signals were identified for NIVO + IPI. Clinical trial information: NCT02477826.

Abstract
e21714 Background: Data from clinical studies demonstrate a long-term survival benefit of nivolumab in previously treated advanced non-small cell lung cancer (NSCLC) patients with overall survival (OS) at two-years of 27%, however real-world data are limited. We report OS in patients pooled from two prospective multi-centre observational cohort studies in France (EVIDENS, NCT03382496) and Germany (ENLARGE, NCT02910999) and a third retrospective registry of patients treated through expanded access to nivolumab in Canada. Methods: Individual patient data from each cohort were pooled and harmonised in eligibility criteria and variable definitions. Included patients had locally advanced or metastatic (stage IIIB/IV) NSCLC, received nivolumab after at least one prior systemic therapy and had no other concurrent primary cancers. OS was estimated from nivolumab initiation until death or censoring using Kaplan-Meier method. Equality of survival distributions across cohorts was measured using log-rank test. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated from unstratified Cox proportional hazards regression models to explore survival among subgroups. Data on bone and liver metastases, PD-L1 and safety were available and analysed for France and Germany only. Results: Data from 2582 patients (48% France; 34% Germany; 18% Canada) were pooled. Baseline characteristics were: median age 66 years, 64% male, 82% ECOG 0-1, 69% 1 prior line of therapy, 68% non-squamous histology, and 18% with brain metastases (treated or untreated). Median follow-up was 8 months. No difference in OS was observed between countries. The 2-year OS was 28% (95%CI 25-31) for all patients, 26% (95%CI 21-31) for squamous histology and 29% (95%CI 26-33) for non-squamous histology. Bone metastases (HR 1.42; 95%CI 1.26-1.60; P= < .0001) and liver metastases (HR 1.60; 95%CI 1.39-1.85; P= < .0001) were associated with shorter survival, while ECOG PS 0-1 (HR 0.61; 95%CI 0.52-0.71; P= < .0001) and PD-L1 positivity (HR 0.75; 95%CI 0.60-0.93; P= < .0001) were associated with prolonged survival. Rates of any grade and grade 3/4 treatment-related adverse events (TRAE) were 32% and 7% respectively. Conclusions: In this three-country pooled analysis of nivolumab in previously treated advanced NSCLC, real-world overall survival at 2-years was consistent with pivotal nivolumab trials overall and in subgroups. Rates of grade 3/4 TRAEs were comparable, but events of lower grade may be underreported in the real world.

Abstract
INTRODUCTION Immune checkpoint inhibitors (ICIs) have improved cancer prognosis but have not been evaluated specifically in sarcomatoid carcinoma (SC), a rare lung cancer subtype with poor prognosis. As such, our study sought to retrospectively assess the efficacy of ICI in SC. METHODS All consecutive patients with centrally confirmed SC treated using ICI as a second-line treatment or beyond between 2011 and 2017 were enrolled. Programmed death-ligand 1 (PD-L1) tumor expression was assessed using immunohistochemistry (SP263 clone) and the tumor mutational burden (TMB) with the Foundation One panel. TMB was considered high if it was greater than or equal to 10 mutations per megabase. RESULTS Overall, 37 patients with SC were evaluated, predominantly men (73%) with a median age of 63.2 years (36.8-79.7) and who were current or former smokers (94.6%). Immunotherapy (nivolumab, 86.5% of cases) was given as a second-line treatment in 54% of the patients and as third-line treatment or beyond in 46% of the patients. The objective response rate was 40.5% and disease control rate was 64.8%, regardless of PD-L1 status. Median overall survival was 12.7 months (range: 0.3-45.7). One-third of patients exhibited early progression. The median PD-L1 expression was 70% (0-100). There was a trend toward higher PD-L1 expression in responsive diseases, with an objective response rate of 58.8% in patients with PD-L1+ and 0% in the one patient with PD-L1- (p = 0.44). The median TMB was 18 (4-39) mutations per megabase, with 87.5% of the cases displaying a high TMB. There was a trend toward higher TMB in responders versus stable or progressive diseases (p = 0.2). CONCLUSIONS Patients with SC exhibited high response rates and prolonged overall survival under ICI treatment. These data support the prospective investigation of ICI in patients with SC who are under first-line treatment.
