COVID-19 is an emerging, rapidly evolving situation. In addition, the benefit observed in patients with PD-L1–amplified tumors irrespective of PD-L1 expression levels suggests other mechanisms that render PD-L1–amplified tumors sensitive to ICIs, including the link with known predictive factors such as TMB. Median (interquartile range) duration of follow-up was 12.6 (5.6-20.4) months.  et al. Most patients (184 [94.8%]) received platinum-doublet chemotherapy before nivolumab and received nivolumab as the second line (94 [48.5%]) or third line (55 [28.4%]) of treatment. Â, Miao Therefore, identifying additional factors that are robustly associated with response to anti–PD-1/PD-L1 immunotherapy remains a major clinical need.  MD, Awad They were not compensated for their time. JAMA Network Open. Other names: anti-programmed cell death-1 (PD-1) monoclonal antibodies, immune checkpoint inhibitors, programmed death-ligand 1 (PD-L1) blocking antibodies What are Anti-PD-1 monoclonal antibodies? Immune checkpoint inhibitors (ICIs) targeting programmed death 1 (PD-1) or its ligand (PD-L1) have offered a subset of cancer patients profound and durable survival benefit and transformed the therapeutic landscape of multiple tumor types, particularly in non–small cell lung cancer (NSCLC).1-6 However, the proportion of patients with NSCLC who respond to ICIs is low; response to the anti–PD-1 antibody nivolumab was confirmed in only approximately 20% of patients in the pivotal randomized phase 3 clinical trials.1,2 More troublesome, PD-1/PD-L1 inhibitors can cause immune-related adverse effects7 as well as hyperprogressive disease.8 Therefore, there have been substantial attempts to discover and validate predictive biomarkers to identify patients who may benefit from PD-1/PD-L1 inhibitors by integrating information from tumors, the tumor microenvironment (TME), and the host immune system.9 To date, tumor PD-L1 expression using companion diagnostics is the only approved biomarker to indicate NSCLC patients for PD-1 axis blockade.  Treatment of the immune-related adverse effects of immune checkpoint inhibitors: a review. , Champiat The significance of PD-L1 CNGs in the context of ICI therapy was originally highlighted in a previous study showing a high rate (87%) of response to nivolumab, including 17% complete response in heavily pretreated Hodgkin lymphoma32 that usually carries a very low level of TMB,33 given that all tumors analyzed by FISH had an increased PD-L1 gene dosage. This prospective, multicenter, investigator-initiated cohort study enrolled patients from 14 hospitals in Japan between July 1, 2016, and December 11, 2018.  KS, Lenkiewicz  F, La  et al.

NIH  RS, Baas We explored the role of PD-1 ligands in regulating graft-versus-host disease (GVHD).  PD-1 blockade with nivolumab in relapsed or refractory Hodgkin’s lymphoma. , Chabanon  Mismatch repair deficiency predicts response of solid tumors to PD-1 blockade. , Le  SJ, Villegas Of note, the 5 PD-L1–amplified tumors exhibited various PD-L1 TPS values, ranging from 4% to 95% (eTable in the Supplement). Oncotarget. Mol Biosyst.  F, Waterkamp  et al. To validate the performance of E1L3N, we used positive and negative controls as follows: (1) immunocytochemistry and immunoblot analyses of PD-L1 in PD-L1–negative NCI-H1299 cells in which PD-L1 was exogenously expressed using the p3 × FLAG-CMV-14 vector (Sigma-Aldrich) and (2) IHC of PD-L1 using SignalSlide PD-L1 IHC Controls (Cell Signaling Technology). USA.gov. The mechanisms by which PD-L1–amplified tumors are associated with long-lasting responses to nivolumab remain unclear. Author Contributions: Dr Inoue had full access to all of the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis. Third, we could not assess TMB and characteristics of the TME, mainly owing to the limited small biopsy samples.  P, Kim  H, Wooten  P,  Pan-cancer immunogenomic perspective on the tumor microenvironment based on PD-L1 and CD8 T-Cell infiltration. , World Medical Association. Findings  First, it is shown that the ligand binding to human PD-1 is associated with significant plasticity within the receptor. The structural rearrangement within the CC′ loop upon complex formation is clearly discernible.  N, Hellmann  Atezolizumab versus docetaxel in patients with previously treated non–small cell lung cancer (OAK): a phase 3, open-label, multicentre randomised controlled trial. , Reck  SJ,  et al. Statistical analysis: Inoue, Inui, Karayama, Yasui. Robust predictors for response to anti–programmed death 1 and its ligand (PD-1/PD-L1) immunotherapy in non–small cell lung cancer (NSCLC) are not fully characterized. Nivolumab was discontinued in 178 patients (91.8%), mainly due to disease progression (135 [69.6%]) and adverse events (37 [19.1%]).  et al.  et al; OAK Study Group. All patients received nivolumab monotherapy at a dose of 3 mg/kg; the dosage was changed to a flat 240-mg dose in August 2018, according to the renewed approval by the Japanese Ministry of Health, Labor, and Welfare.  Fluorescence In Situ Hybridization Analysis of Programmed Death Ligand 1 (, Figure 2.  Mutational landscape and sensitivity to immune checkpoint blockers. , Goodman  S, Okamoto Results   K, Â, Ock  T, Rizvi Guzik K, Zak KM, Grudnik P, Magiera K, Musielak B, Törner R, Skalniak L, Dömling A, Dubin G, Holak TA.  et al. Gly124 Cleft ( L Tyr123-Accommodating Cavity) and CC′ Loop Rearrangement Are Induced by…, Figure 4.  A, Biomarker evaluation samples were obtained mainly from primary lesions through several procedures, and the median (IQR) interval between the date of sample collection and nivolumab therapy initiation was 10.7 (5.8-16.8) months, with 111 samples (57.2%) collected within 12 months before treatment. PD-L1 is a transmembrane protein that belongs to the Ig superfamily consisting of an extracellular N-terminal V domain (IgV) and one C domain (IgC) connected by a short linker.1 H-15 N … PD-L1 is encoded by the PD-L1 gene (CD274; OMIM 605402) located on the chromosome band 9p24.1. This might have been caused by the spatially more heterogeneous nature of PD-L1 expression than copy number,22,37 which was particularly relevant for this study because of the small biopsy specimens used in most cases. Survival data were estimated using the Kaplan-Meier method, and the log-rank test was used to compare the differences in survival durations.

(A and B) Surface representation of the hPD-L1 binding site of hPD-1.  E, PD-L1 expression was regarded as positive if membranous expression at any intensity was observed. This multicenter cohort study enrolled 200 patients, of whom 194 had assessable tumors, with advanced or recurrent NSCLC who were treated with nivolumab after progression following prior treatment at 14 institutions in Japan between July 2016 and December 2018. Dublin, Oct. 09, 2020 (GLOBE NEWSWIRE) -- The "Programmed Death-Ligand 1 (PD-L1) Non-Small Cell Lung Cancer (NSCLC)-Market Insights, Epidemiology and Market Forecast - 2030" … Despite being hampered by the low prevalence, this association appears to be more clinically meaningful than selection of patients based on PD-L1 expression at any threshold applied.  S, Stein  DT, Uram Please enable it to take advantage of the complete set of features! OS was defined as the interval from the date of the first administration of nivolumab to the date of death from any cause. We excluded patients with concomitant autoimmune diseases, interstitial lung diseases, uncontrolled symptomatic brain metastases, or other severe uncontrolled complications.  KN, Cancer Treat Rev. Correlation coefficients between continuous variables of biomarkers were calculated according to Spearman. Based on the encouraging preclinical and clinical studies suggesting the promise of PD-1 axis blockade in PD-L1–amplified tumors, we examined whether increased PD-L1 gene dosage in NSCLC tumors is associated with a greater magnitude of efficacy of nivolumab.
