Expression data in human renal cell carcinoma samples from patients who did or did not respond to anti-PD-1 (Nivolumab) immunotherapy

ABSTRACT: 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.

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.

Immunomodulatory response to neoadjuvant nivolumab in non-metastatic clear cell renal cell carcinoma

Project description:Novel perioperative strategies are needed to reduce recurrence rates in patients undergoing nephrectomy for high-risk, non-metastatic clear cell renal cell carcinoma (ccRCC). We conducted a prospective, phase I trial of neoadjuvant nivolumab prior to nephrectomy in 15 evaluable patients with non-metastatic ccRCC. We leveraged tissue from that cohort to elucidate the effects of PD-1 inhibition on immune cell populations in ccRCC and correlate the evolving immune milieu with anti-PD-1 response. We found that nivolumab durably induces a pro-inflammatory state within the primary tumor, and baseline immune infiltration within the primary tumor correlates with nivolumab responsiveness. Nivolumab increases CTLA-4 expression in the primary tumor, and subsequent nephrectomy increases circulating concentrations of sPD-L1, sPD-L3 (sB7-H3), and s4-1BB. These findings form the basis to consider neoadjuvant immune checkpoint inhibition (ICI) for high-risk ccRCC while the tumor remains in situ and provide the rationale for perioperative strategies of novel ICI combinations.

Immune and inflammation-related factors alteration as a biomarker for predicting prognosis and responsiveness to PD-1 monoclonal antibody in patients with recurrent cervical cancer

Project description:Purpose: We aimed to elucidate the potential mechanisms of effective responsiveness to PD-1 monoclonal antibody and evaluate more reliable biomarkers for improving the predictive utility of the dominant populations of recurrent cervical cancer (RCC) to receive immunotherapy. Methods: Peripheral blood samples of PD-L1 positive patients with RCC treated with second-line PD-1 monoclonal antibody were collected prior to treatment initiation and after the treatment. Differentially expressed genes (DEGs) were analyzed between partial response (PR) patient and progressive disease (PD) patients.

Transcriptional mechanisms of resistance to anti-PD-1 therapy

Project description:Gene expression in 10 skin metastases from a patient with melanoma who had been treated with anti-PD-1 (Nivolumab) therapy was measured. Differences in gene expression between the lesions which responded to the treatment (n = 6) and the lesions which progressed (n = 4) were analyzed. Expression of certain genes associated with the extracellular matrix and with neutrophil function was found to be higher in the metastases which progressed. Insight into the biology governing response to immunotherapy may lead to improved rationally designed therapies, and to biomarkers for selecting patients who are more likely to benefit from these treatments.

Pilot Trial of Arginine Deprivation plus Nivolumab and Ipilimumab in Patients with Metastatic Uveal Melanoma

Project description:Metastatic uveal melanoma (UM) remains challenging to treat, with objective response rates to immune checkpoint blockade (ICB) much lower than in primary cutaneous melanoma (CM). Besides a lower mutational burden, the overall immune-excluded tumor microenvironment of UM might contribute to the poor response rate. We therefore aimed at targeting deficiency in argininosuccinate synthase 1, which is a key metabolic feature of UM. This study aimed at investigating safety and tolerability of a triple combination consisting of ipilimumab and nivolumab immunotherapy and the metabolic therapy ADI-PEG 20. 9 patients were enrolled in this pilot study. The combination therapy was safe and tolerable with absence of immune related adverse events (irAE) of special interest but with 4 of 9 patients experiencing a CTCAE grade 3 AE. No objective responses were observed. All except one patient developed anti-drug antibodies (ADA) within a month of treatment initiation and therefore did not maintain arginine depletion. Further, an IFNg-dependent inflammatory signature was observed in metastatic lesions in patients pre-treated with ICB compared with patients with no pretreatment. Multiplex immunohistochemistry demonstrated variable presence of tumor infiltrating CD8 lymphocytes and PD-L1 expression at baseline in metastases.

Soluble immune-checkpoint factors as a complementary biomarker for PD-1 blockade reflect exhaustion of antitumor immunity

Project description:BACKGROUND. Precise stratification of patients with non–small cell lung cancer (NSCLC) is needed for appropriate application of PD-1/PD-L1 blockade therapy. METHODS. We measured soluble (s) forms of the PD-L1, PD-1, and CTLA-4 in plasma of patients with advanced NSCLC before PD-1/PD-L1 blockade. Prospective biomarker finding trial (cohort A), 50 patients with pretreated NSCLC received nivolumab. In cohort B to E, retrospective observational study, soluble immune checkpoint molecules were evaluated for patients with advanced NSCLC treated with any PD-1/PD-L1 blockade (cohort B and C), cytotoxic chemotherapy (D) or targeted therapy (E). Blood samples were obtained from all patients and soluble immune checkpoint molecules were evaluated using a highly sensitive chemiluminescence-based assay. RESULTS. Nonresponsiveness to PD-1/PD-L1 blockade therapy was associated with higher concentrations of these soluble immune factors among patients with immune-reactive (hot) tumors. Such correlation was not observed in patients treated with cytotoxic chemotherapy or targeted therapies. Integrative analysis of tumor size, PD-L1 expression in tumor tissue (tPD-L1), and gene expression in tumor tissue and peripheral CD8+ T cells revealed that high concentrations of the three soluble immune factors were associated with hyper or terminal exhaustion of antitumor immunity. The combination of sPD-L1 and sCTLA-4 efficiently discriminated responsiveness among patients with immune-reactive tumors. CONCLUSION. Combinations of soluble immune factors might be able to identify patients unlikely to respond to PD-1/PD-L1 blockade as a result of terminal exhaustion of antitumor immunity. Our data suggest such a combination might provide a biomarker complementary to tPD-L1 for NSCLC patients.

Expression data in PD-L1 positive and PD-L1 negative human melanoma samples

Project description:Blocking the PD-1/PD-L1 immunosuppressive pathway has shown promise in the treatment of certain cancers including melanoma. This study investigates differences in the gene expression profiles of human melanomas that do or do not display the immunosuppressive protein PD-L1. Further understanding of genes expressed within the tumor microenvironment of PD-L1+ tumors may lead to improved rationally designed treatments. Gene expression profiling was performed on total RNA extracted by laser capture microdissection from 11 archived formalin-fixed paraffin-embedded (FFPE) melanoma specimens, 5 of which were PD-L1 positive and 6 PD-L1 negative. Details of the design, and the gene signatures found are given in the paper associated with this GEO Series: Janis M. Taube, Geoffrey D. Young, Tracee L. McMiller, Shuming Chen, January T. Salas, Theresa S. Pritchard, Haiying Xu, Alan K. Meeker, Jinshui Fan, Chris Cheadle, Alan E. Berger, Drew M. Pardoll, and Suzanne L. Topalian, Differential expression of immune-regulatory genes associated with PD-L1 display in melanoma: implications for PD-1 pathway blockade, Clin Cancer Res 2015, in press.
