Project description:Immune checkpoint blockade is promising for treating non-small-cell lung cancer (NSCLC). We used multipanel markers to predict the response to immune checkpoint inhibitors (ICIs) by characterizing gene expression signatures or individual genes in patients who showed durable clinical benefit to ICIs. Twenty-one patients with NSCLC treated with single-agent anti-programmed cell death protein (PD)-1 antibody were analyzed and their clinicopathological characteristics and response to ICIs were characterized. Targeted sequencing of tissue-extracted DNA and RNA was performed using the Oncomine Immune Response Research Assay to evaluate 395 genes involved in the immune response and calculate the tumor mutation burden. Nine (43%) showed a durable clinical benefit (DCB), while the remaining 12 (57%) patients showed non-durable benefit (NDB). The M1 and peripheral T cell signatures showed the best performance for discriminating DCB from NDB (sensitivity, specificity, accuracy = 0.89, 1.0, 0.95, respectively). Progression-free survival (PFS) was significantly longer in patients with high M1 signature or high peripheral T cell signature scores. CD137 and PSMB9 mRNA expression was higher in the DCB group than in the NDB group. Patients with high PSMB9 expression showed longer PFS. M1 signature, peripheral T cell signature and high mRNA expression level of CD137 and PSMB9 showed better predictive performance than known biomarkers (PD-L1, tumor infiltrating lymphocytes, tumor mutation burden). M1 and peripheral T cell signature of tumors may enable prediction of durable response and maximize the benefit of ICIs in patients with NSCLC.

Project description:Immune checkpoint blockade has revolutionized cancer therapy. In particular, inhibition of programmed cell death protein 1 (PD-1) is effective for the treatment of metastatic melanoma and other cancers. Despite a dramatic increase in progression-free survival, a large proportion of patients do not show durable response. Therefore, predictive biomarkers of clinical response are urgently needed. Here, we employed high-dimensional single cell mass cytometry and a bioinformatics pipeline for the in-depth characterization of the immune cell subsets in the peripheral blood of metastatic melanoma patients before and after anti-PD-1 immunotherapy. During therapy, we observed a clear treatment response to immunotherapy in the T cell compartment. However, prior to commending therapy a strong predictor of progression free and overall survival in response to anti-PD-1 immunotherapy was the frequency of CD14+CD16-HLA-DRhi monocytes. We could confirm this by conventional flow cytometry in an independent validation cohort and propose this as a novel predictive biomarker for therapy decisions in the clinic. In order to determine whether there are cell intrinsic changes in the monocyte signature, we performed RNA sequencing on sorted CD14+CD16-HLA-DRhi cells from HD, NR and R at baseline. Representative samples (n=4, each) of responders/non responders/ and healthy donors were selected from archival samples stored in the dermatology biobank according to the same clinical criteria used in the discovery and validation cohorts for CyTOF and FACS analysis. CD14+CD16-HLA-DRhiLin- (CD3, CD4, CD19, CD45RO) monocytes were sorted from frozen PBMC form blood samples from HD, R and NR at baseline.

Project description:Immunotherapy has opened hitherto unknown possibilities to treat cancer. Whereas some cancer types (e.g. melanoma) can be efficiently treated, others lack measurable positive effects (e.g. PDAC). Moreover, stratification of responders/non-responders is only possible in some cancer types (e.g. melanoma). Hepatocellular carcinoma (HCC) has a dismal prognosis, limited treatment options and survival benefit, and represents a potential cancer entity for successful immunotherapy. Here, we investigated NASH-triggered HCC in the context PD-1-targeted immunotherapy. Using flow cytometry, single cell RNA sequencing, immunohistochemistry and mass spectrometric analyses, we found a progressive increase of CD8+PD-1+ effector T-cells with a unique profile of exhaustion and activation markers rising with murine and human NASH severity. Notably, late-stage HCC treatment with PD-1-targeted immunotherapy enhanced hepatic carcinogenesis in mice. Dissecting potential mechanisms of action during tumor-initiation and -progression we analyzed the effects of PD-1-targeted immunotherapy at HCC initiation. PD-1-targeted immunotherapy induced a pro-tumorigenic environment, enhanced necro-inflammation and increased NAFLD-activation score (NAS), leading to increased liver cancer incidence, tumor number and nodule size. In contrast, anti-CD8 or anti-CD8/anti-NK1.1 treatment reduced NAS and abrogated the development of liver cancer, thus identifying CD8+PD-1+ T-cells as drivers of liver cancer in NASH-triggered HCC. Increased apoptotic signaling, STAT3 phosphorylation and hepatic proliferation were detected in intra-tumoral liver tissue upon PD-1-targeted immunotherapy. In line, PD-1-/- mice challenged with a NASH diet displayed early onset of hepatocarcinogenesis, corroborating the pro-tumorigenic role of absent or reduced PD-1. Mechanistically PD-1-targeted immunotherapy mainly affected hepatic abundance of CD8+PD-1+ T-cells, instead of altering the quality of Tox+CXCR6+ expressing CD8+PD-1+TNF+CD39+Gzmb+ T-cells found in NASH livers, leading to an aggressive, pro-tumorigenic liver environment. Single-cell mapping of human NASH-, borderline NASH- or unaffected livers corroborated our preclinical NASH results. Moreover, in human NASH livers a correlation of hepatic CD8+, PD-1+, TNF+ T-cells with fibrosis and NASH severity was observed. Accordingly, HCC patients with NASH etiology display a sharp increase in intra- and peri-tumoral CD8+ PD-1+ T-cells. In a cohort of 65 patients recruited across 6 centers in Germany and Austria, patients with NAFLD/NASH-driven HCC responded worse to PD-1-targeted immunotherapy by Nivolumab or Pembrolizumab compared to non-NAFLD patients. This resulted in significant reduced overall survival, in trends of faster disease progression and reduced progression free survival. Histological analysis of livers derived from HCC patients treated with PD-1-targeted immunotherapy displayed high levels of intra and peri-tumoral CD8+ PD-1+ T-cells and Ki67+ hepatocytes. Taken together, these data indicate that PD-1-targeted immunotherapy induces immune-related adverse effects in NAFLD/NASH-driven HCC through CD8+PD-1+ T-cells. Our data call for stratification of HCC patients subjected to PD-1-targeted immunotherapy, with NAFLD being a negative predictor.

Project description:Treatment with immune checkpoint inhibitors has altered the course of malignant melanoma, with approximately half of the patients with advanced disease surviving for more than 5 years after diagnosis. Currently, there are no biomarker methods for predicting outcome from immunotherapy. Here, we obtained transcriptomic information from a total of 105 baseline tumor samples comprising two cohorts of patients with advanced melanoma treated with programed cell death protein 1 (PD-1)-based immunotherapies. Gene expression profiles were correlated with progression-free survival (PFS) within consecutive clinical benefit intervals (i.e., 6, 12, 18, and 24 months). Elastic net binomial regression models with cross validation were utilized to compare the predictive value of distinct genes across time. Lasso regression was used to generate a signature predicting long-term benefit (LTB), defined as patients who remain alive and free of disease progression at 24 months post treatment initiation. We show that baseline gene expression profiles were consistently able to predict long-term immunotherapy outcomes with high accuracy. The predictive value of different genes fluctuated across consecutive clinical benefit intervals, with a distinct set of genes defining benefit at 24 months compared to earlier outcomes. A 12-gene signature was able to predict LTB following anti-PD-1 therapy with an area under the curve (AUC) equal to 0.92 and 0.74 in the training and validation set, respectively. Evaluation of LTB, via a unique signature may complement objective response classification and characterize the logistics of sustained antitumor immune responses.

Project description:Pre-treatment tumor expression of PD-L1 has been shown to correlate with favorable clinical outcomes following PD-1 blocking therapies. However, the majority of patients with PD-L1+ tumors do not respond to treatment. With the goal of obtaining insights into the mechanisms underlying the response to anti-PD-1 targeted therapies in patients with renal cell carcinoma (RCC) with positive tumor expression of PD-L1, microarray expression data was obtained for pre-treatment tumors from patients with RCC who did or did not have a positive response to anti-PD-1 (nivolumab) therapy. Insight into these mechanisms may lead to improved rationally designed therapies, and biomarkers for selecting patients who are more likely to benefit from these treatments. Gene expression profiling was performed on total RNA extracted from 11 formalin-fixed paraffin-embedded (FFPE) RCC specimens, 4 of which were from patients who had a positive response (objective tumor regression) to the anti-PD-1 (nivolumab) immunotherapy, and 7 of which were from patients who did not have a response. Details of the design, and the gene signatures found are given in the paper associated with this GEO Series: Maria Libera Ascierto, Tracee L. McMiller, Alan E. Berger, Ludmila Danilova, Robert A.

Project description:Therapeutic strategies that enhance anti-viral immunity and reduce the viral reservoir are critical to achieving durable remission of HIV. The co-inhibitory receptor programmed death-1 (PD-1) regulates CD8+ T cell dysfunction during chronic HIV and SIV infections 1-4. In addition, PD-1+ CD4+ T cells constitute a significant fraction of the HIV/SIV viral reservoir5-7. We previously demonstrated that in vivo blockade of PD-1 during chronic SIV infection improves the function of anti-viral CD8+ T cells and B cells 4,8. However, the immunological effects of PD-1 blockade during anti-retroviral therapy (ART) and the potential to destabilize the persistent HIV/SIV reservoir have not been studied. Here, we show that administration of anti-PD-1 antibody (PD-1 Ab) 10 days prior to initiation of ART rapidly enhanced anti-viral CD8+ T cell function and diminished interferon stimulated genes (ISGs) that resulted in markedly improved viral suppression in plasma and better Th17 cell reconstitution in the rectal mucosa following ART initiation. In addition, PD-1 blockade during suppressive ART resulted in transient increases in plasma viremia, induction of gene signatures associated with effector CD8+ T cell function and ISGs, and lower levels of cell associated replication-competent virus suggesting destabilization of the viral reservoir. Following ART interruption, PD-1 Ab treated animals showed markedly higher expansion of proliferating CXCR5+ Perforin+ Granzyme B+ effector CD8+ T cells and lower regulatory T cells that resulted in delayed viral rebound and better control of viremia. PD-1 blockade administered only during suppressive ART however was only partially effective. Our results indicate an optimal regimen of PD-1 blockade administered in combination with ART, that augments anti-viral CD8+ T cell function and reduces the viral reservoir leading to improved control of viral rebound after ART interruption. These results have important implications for developing novel therapeutic interventions to achieve durable remission of HIV.

Project description:Anti-PD-1 (aPD1) immunotherapy likely affects other immune cells including follicular helper CD4 T cells (Tfh) involved in germinal center (GC) responses. Little is known, however, about the effects of anti-PD-1 immunotherapy on non-cancer immune responses in humans. To investigate this question, we examined the impact of aPD1 immunotherapy for cancer on the Tfh-B cell axis responding to unrelated viral antigens. Following influenza vaccination, a subset of adults receiving aPD1 had more robust circulating Tfh (cTfh) responses than adults not receiving immunotherapy, and cTfh responses correlated with plasmablasts. PD-1 pathway blockade also resulted in transcriptional signatures of increased cellular proliferation in cTfh and responding B cells compared to controls.
