Immunologically hot phenotype is associated with response to PD-1/PD-L1 inhibitors in patients with advanced head and neck squamous cell carcinoma.

Project description:Ongoing immunomodulatory strategies in tumors characterized by an overall hot immune phenotype may improve prognosis of head and neck squamous cell carcinomas (HNSCC). Our objective was to develop a reliable and stable scoring system for the identification of immunologically hot HNSCC and to evaluate its association with response to immunotherapies. A Hot Oral Tumor (HOT) score was developed using data from The Cancer Genome Atlas. HOT score was computed in 102 patients with HNSCC treated with immunotherapy targeting PD-1/PD-L1 in the context of clinical trials. High HOT score was associated with a statistically significant improved clinical outcome.

Immunologically active phenotype is associated with response to PD-1/PD-L1 inhibitors in patients with advanced non-small cell lung cancer

Project description:Immunotherapy in immunologically active tumors may improve prognosis of non-small cell lung carcinomas (NSCLC). Our objective was to develop a reliable and stable scoring system for the identification of immunologically active HNSCC and to evaluate its association with response to immunotherapies. A Hot Oral Tumor (HOT) score was developed using data from The Cancer Genome Atlas in human-papillomavirus negative head and neck squamous cell carcinomas; it was computed in 92 patients with early stage NSCLC treated with surgery to evaluate the prognostic impact of the HOT score.

Immunologically hot phenotype is associated with response to second-line PD-1/PD-L1 inhibition in patients with advanced non-small cell lung cancer

Project description:Ongoing immunomodulatory strategies in tumors characterized by an overall hot immune phenotype may improve prognosis of patients with non-small cell lung cancer (NSCLC). Our objective was to develop a reliable and stable scoring system for the identification of immunologically hot NSCLC and to evaluate its association with response to immunotherapies. A Hot Oral Tumor (HOT) score was developed using data from The Cancer Genome Atlas. HOT score was computed in 82 patients with NSCLC treated with second-line immunotherapy targeting PD-1/PD-L1. High HOT score was associated with a statistically significant improved clinical outcome.

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.

PD-L1 blockade in combination with inhibition of MAPK oncogenic signaling in patients with advanced melanoma

Project description:Combining PD-L1 blockade with inhibition of oncogenic mitogen-activated protein kinase (MAPK) signaling may result in long-lasting responses in patients with advanced melanoma. This phase 1, open-label, dose-escalation and -expansion study (NCT02027961) investigated safety, tolerability and preliminary efficacy of durvalumab (anti–PD-L1) combined with dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) for patients with BRAF-mutated melanoma (cohort A, n=26), or durvalumab and trametinib given concomitantly (cohort B, n=20) or sequentially (cohort C, n=22) for patients with BRAF-wild type melanoma. Adverse events and treatment discontinuation rates were more common than previously reported for these agents given as monotherapy. Objective responses were observed in 69.2% (cohort A), 20.0% (cohort B) and 31.8% (cohort C) of patients, with evidence of improved tumor immune infiltration and durable responses in a subset of patients with available biopsy samples. In conclusion, combined MAPK inhibition and anti–PD-L1 therapy may provide treatment options for patients with advanced melanoma.

Gene-expression profiles of PD-L1-affected CD8+ T cells

Project description:Programmed cell death 1 ligand 1 (PD-L1) is known to suppress immune system and to be an unfavorable prognostic factor in ovarian cancer. The purpose of this study was to elucidate the function of PD-L1 in peritoneal dissemination. Tumor cell lysis by CTLs was attenuated when PD-L1 on tumor cells was overexpressed and promoted when it was silenced. PD-L1 overexpression also inhibited gathering and degranulation of CTLs. Gene expression profile of mouse CTLs caused by PD-L1-overexpressing ovarian cancer was related to human CTLs exhaustion. In mouse ovarian cancer dissemination models, depleting PD-L1 expression on tumor cells resulted in inhibited tumor growth in the peritoneal cavity and prolonged survival. Restoring immune function by inhibiting immune-suppressive factors such as PD-L1 may be a promising therapeutic strategy for peritoneal dissemination. Genome-wide transcriptional changes in OT-1 mouse CD8+ T cells that were co-incubated with OVA peptide-loaded ID8 mouse ovarian cancer cell lines. CTLs from 4 mice were devided into 2 groups, and co-incubated with PD-L1-overexpressed ID8 or PD-L1-depleted ID8.

Tumor PD-L1 engages myeloid PD-1 to suppress type I interferon to impair cytotoxic T lymphocyte recruitment (bulk)

Project description:A hallmark of PD-1/L1 blockade is long-term, sustained remission of metastatic disease. How the immune system coordinates the destruction of macro- and micro-metastases following checkpoint blockade, however, remains unclear. Here, we show that tumor-expressed PD-L1 (tPD-L1) enhanced metastasis in a mechanism distinct from and independent of its role in primary tumor growth. This difference in metastatic growth was mediated by cytotoxic T lymphocytes (CTLs), however, tPD-L1 did not promote effector CTL exhaustion or suppress lytic activity in vivo. Instead, single cell RNA sequencing revealed that tPD-L1 engaged macrophage-expressed PD-1 to antagonize type I interferon production and signaling, creating an immunologically ‘cold’ microenvironment. Loss of tPD-L1 eliminated metastases by driving interferon-mediated sensitization of tumor cells to CTL lysis and CTL recruitment.
