programmed death ligand 1 pd l1

 D, Kato  A, Barlesi In contrast to our hypothesis that low-grade PD-L1 CNGs represented as polysomy would derive limited benefit from nivolumab therapy, no benefit in response and survival was observed, suggesting distinct roles for PD-L1 amplification and polysomy in tumor immune evasion.  Genomic correlates of response to immune checkpoint blockade. , Green This site needs JavaScript to work properly. We thank the Edanz Group for editing a draft of this article. Although somatic genomic features, such as variations and copy number alterations, have been associated with response and resistance to ICIs,30,31 tumor PD-L1 copy number status has received limited attention in solid tumors. Survival data were estimated using the Kaplan-Meier method, and the log-rank test was used to compare the differences in survival durations.

Genomic amplification of 9p24.1 targets Janus kinase 2 (JAK2) as well as PD-L1 and PD-L2, resulting in enhanced expression of JAK2 that further augments PD-L1 induction.36 This positive circuit makes the amplification of this locus more impactful in terms of constitutive PD-L1 expression and provides a rationale for response to anti–PD-1/PD-L1 inhibitors.  KP, Van Allen A total of 6 of the 200 patients were excluded because of poor-quality tumor specimens for the biomarker study, resulting in 194 assessable patients.

As a result, median duration of response was not reached (range, 17.7 [ongoing] to 33.7 [ongoing] months) for patients with PD-L1 amplification who responded, which was longer than that among patients with PD-L1 polysomy who responded (14.9 months; 95% CI, 4.6 months to not reached) or those with disomy who responded (16.8 months; 95% CI, 8.1 months to not reached) (eFigure 3A in the Supplement). An OS benefit for patients with high expression of PD-L1 compared with those with low expression of PD-L1 was observed at the PD-L1 TPS threshold of 50% (HR, 0.44; 95% CI, 0.23-0.84; P = .01) (eFigure 8A in the Supplement), but again, no significant benefit was observed at lower PD-L1 TPS thresholds (eFigures 8B, 8C, and 8D in the Supplement).  RM, Pedrero Indeed, previously treated patients with NSCLC who had PD-L1 expression of at least 50% had more response to pembrolizumab compared with those with PD-L1 expression between 1% and 50%.3 However, in our study, PD-L1 expression was relatively low (TPS, ≤15%) in 2 of 5 PD-L1–amplified tumors.  Detection of chromosome changes in pathology archives: an application of microwave-assisted fluorescence in situ hybridization to human carcinogenesis studies. , Kanda The number of PD-L1 expression–positive cases at different TPS thresholds were 86 (44.3%) at TPS 1%, 73 (37.6%) at TPS 5%, 61 (31.4%) at TPS 10%, and 24 (12.4%) at TPS 50%.

The Kruskal-Wallis test was used for continuous variables, followed by adjustment using the method of Holm. 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. A total of 6 of the 200 patients were excluded because of poor-quality tumor specimens for the biomarker study, resulting in 194 assessable patients. In contrast, the 1-year PFS and 1-year OS rates were only 18.5% (95% CI, 6.7%-34.8%) and 46.0% (95% CI, 26.4%-63.6%) for patients with PD-L1 polysomy and 20.8% (95% CI, 14.8%-27.4%) and 57.6% (95% CI, 49.6%-64.8%) for patients with PD-L1 disomy, respectively.

PD-L1 copy number was assessed by centrally performed FISH using the Histra PD-L1 FISH kit (Jokoh, Tokyo, Japan) as described elsewhere.22,28 This kit contains the spectrum orange-labeled bacterial artificial chromosome clone RP11-599H20 (9p24.1, PD-L1; Advanced GenoTechs) and the spectrum green-labeled control centromere enumeration probe for chromosome 9 (CEP9; RP11-113O24; Advanced GenoTechs) as PD-L1 locus–specific and referenced chromosome 9 FISH probes, respectively. Close-Up Views of the hPD-1/hPD-L1…, Figure 2. Genomic amplification of this locus is associated with distinct features in multiple tumor types.19-21 We previously reported that PD-L1 copy number gains (CNGs), including amplification and polysomy, as determined by fluorescence in situ hybridization (FISH), were associated with greater PD-L1 expression in NSCLC,22 suggesting that PD-L1 CNGs are responsible for innate immune resistance through constitutive upregulation of PD-L1. PFS was defined as the time between the date of the first administration of nivolumab and the date of progression, defined by RECIST version 1.1, or death due to any cause. Findings  Dr Suda reported receiving grants from Boehringer Ingelheim, AstraZeneca, Takeda Pharmaceutical Company, Kyorin Pharmaceutical Company, Shionogi and Co, Taiho Phamaceutical Co, Daiichi Sankyo Healthcare, and Pfizer outside the submitted work. To evaluate whether PD-L1 (CD274) copy number gains (CNGs), comprising amplification and polysomy, in pretreatment specimens assessed by fluorescence in situ hybridization are associated with response to nivolumab monotherapy in NSCLC. Our aim was … Nivolumab was discontinued in 178 patients (91.8%), mainly due to disease progression (135 [69.6%]) and adverse events (37 [19.1%]). The CC′ loop is marked by the blue circle, the. We excluded patients with concomitant autoimmune diseases, interstitial lung diseases, uncontrolled symptomatic brain metastases, or other severe uncontrolled complications. Pretreatment tumor samples were collected for biomarker evaluation.  TA, Postow Overall, 3 PD-L1-amplified tumors (60.0%) showed PD-L1 TPS of at least 80%, but 2 (40.0%) had PD-L1 TPS of 15% or less.  et al.  KL, Baas The median (IQR) follow-up period among 67 patients who were censored was 20.5 (15.4-30.4) months.  Patient and Tumor Characteristics at Baseline, Brahmer Median (interquartile range) duration of follow-up was 12.6 (5.6-20.4) months. 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. No patients received ICIs before nivolumab. However, this patient subsequently experienced no disease progression until final database lock, receiving no other systemic antitumor therapy.  D, Robinson グナルの亢進／抑制に働く CD28/CTLA-4 ファミリーに属する、50～55 kDa のI型膜たんぱく質です。. Of these, 155 (79.9%) were men, with a median (range) age of 69 (43-83) years. However, the reported very low prevalence (0.7%) of PD-L1 amplification, defined as at least 6 copies, assessed by comprehensive genomic profiling across more than 100 types of solid tumors,34 has been considered a major limitation of its widespread use in clinical practice.35 Nevertheless, our previous report22 and the present study showed that PD-L1 amplification was detected in approximately 3% of patients with NSCLC as assessed by FISH.  DT, Uram  et al.

We calculated that a group of 200 individuals would contain approximately 40 patients with tumors carrying PD-L1 CNGs, based on a prevalence of approximately 20%.22 Although no formal hypothesis testing was planned, we assumed that ORR to nivolumab would be approximately 30% in patients with tumors harboring PD-L1 CNGs. Tumor specimens that contained fewer than 100 tumor cells or showed low quality were excluded from FISH and IHC analyses. Programmed death-ligand 1, commonly abbreviated PD-L1, is a protein with an important role in immune system regulation and cancer.

Most patients were men (155 [79.9%]) and had a history of smoking (162 [83.5%]), PS 0 or 1 (186 [95.9%]), and stage IV disease (136 [70.6%]). 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.  JN, Smith The remaining patient with PD-L1 amplification who did not respond obtained stable disease, demonstrating evidence of antitumor effects, with tumor regression of 20%, as shown in the waterfall plot (eFigure 5 in the Supplement).

Water molecules are shown as red spheres.
