Indoleamine 2,3-dioxygenase 1 (IDO1), involved in the catabolism of tryptophan (Trp) to kynurenine (Kyn) is an important regulator of tumor-mediated immunosuppression implicated in resistance to anti-PD1 immunotherapy. We investigated the role of IDO1 in an anti-PD1-resistant lung cancer model (344SQ_R) compared to the parental 344SQ tumors (344SQ_P). IDO1 was overexpressed in tumor-infiltrating leukocytes, and plasma Kyn levels were increased, in 344SQ_R vs. 344SQ_P. The IDO1 inhibitor INCB023843 retarded tumor growth and reduced lung metastases in 344SQ_R...

INTRODUCTION: Anti-PD1 (programmed cell death protein 1) therapy can lead to unconventional tumor responses including radiologic pseudoprogression. Here we determine the real-world incidence of radiologic pseudoprogression in advanced non-small cell lung cancer (NSCLC) and compare radiologic response criteria for disease response assessment. METHODS: Electronic medical records of all NSCLC patients receiving anti-PD1 therapy at our institution over a 3-year period were retrospectively reviewed and patients with clinically suspected radiologic pseudoprogression identified...

Nivolumab is an anti-PD1 antibody, given in second-line or later treatment in advanced non-small cell lung cancer (NSCLC). The objective of this study was to describe the predictive value of circulating tumor DNA (ctDNA) on the efficacy of nivolumab in advanced NSCLC. We prospectively included all consecutive patients with advanced NSCLC treated with nivolumab in our Department between June 2015 and October 2016. Plasma samples were obtained before the first injection of nivolumab and at the first tumor evaluation with nivolumab...

BACKGROUND: PD-L1 expression determination defines eligibility for treatment with pembrolizumab in patients with advanced non-small cell lung cancer (NSCLC). This study was designed to better define which value across core biopsies from the same case more closely reflects the PD-L1 expression status on whole sections and how many biopsies are needed for confident classification of tumors in terms of PD-L1 expression. MATERIALS AND METHODS: We built tissue microarrays as surrogate of biopsies collecting 5 cores per case from 268 cases and compared PD-L1 staining results using validated clone SP263 with tumor whole sections...

BACKGROUND: Programmed death receptor-1 blocking antibodies (anti-PD1) are a new standard of care in many cancer types. Patients benefit from improved survival but have the risk of immune-related adverse events (irAE). We evaluated if medical imaging procedures, used for anti-tumour response assessment, can detect irAEs. MATERIALS AND METHODS: All consecutive patients treated with anti-PD1 and with a medical imaging acquisition performed within 2 weeks with irAEs ≥2 were retrospectively included...

Background: There are well-known differences in gender outcome in non-small cell lung cancer (NSCLC) and other cancers. In this work, we evaluated several randomised clinical trials to explore the gender influence in the outcome of patients with NSCLC treated with targeted therapy and immunotherapy. Methods: We performed a series of meta-analysis to compare the gender outcome in the routine setting for overall survival and progression-free survival (PFS) in phase III randomised clinical trials comparing EGFR inhibitors versus chemotherapy (OPTIMAL, LUX-lung 3, LUX-lung 6, EURTAC, ENSURE and WTJOG); ALK inhibitors versus chemotherapy (ASCEND 4, ASCEND 5, PROFILE 1014 and NCT009323893) and anti-PD1 checkpoint inhibitors versus chemotherapy (CheckMate 017, CheckMate 026, CheckMate 057, KEYNOTE 010 and KEYNOTE 024)...

BACKGROUND: Precision medicine and prediction of therapeutic response requires monitoring potential biomarkers before and after treatment. Liquid biopsies provide noninvasive prognostic markers such as circulating tumor DNA and RNA. Circulating tumor RNA (ctRNA) in blood is also used to identify mutations in genes of interest, but additionally, provides information about relative expression levels of important genes. In this study, we analyzed PD-L1 expression in ctRNA isolated from various cancer types...

Immune checkpoint inhibitors enhance the activation and antitumor activity of the immune system, resulting in durable response rates in a select group of patients. Cytotoxic T lymphocyte antigen 4 (CTLA4) inhibitors target the inhibitory interaction between CTLA4 and CD80 or CD86. Programmed death 1 (PD1) inhibitors target the interaction between PD1 receptors on T-cells and PD-ligand 1 (PD-L1) and PD-ligand 2, blocking the inhibitory signaling and resulting in activation of T-cell effector function. These therapeutic drugs were originally evaluated in patients with metastatic melanoma before expansion to all tumor types, including non-small cell lung cancer (NSCLC) with promising results...

Lung cancer is the leading cause of cancer death in France with low response rates to conventional chemotherapy. Nevertheless, new therapies have emerged recently, among which PD1 immune checkpoint inhibitors (ICI), such as nivolumab (OPDIVO® , Bristol-Myers Squibb) and pembrolizumab (KEYTRUDA® , Merck & Co), or PD-L1 ICI, such as atezolizumab (TECENTRIQ® , Genentech), durvalumab (IMFINZI® , Astra-Zeneca), and avelumab (BAVENCIO® , EMD Serono). The prescription of pembrolizumab for advanced stages non-small cell lung carcinoma (NSCLC) patients requires the demonstration of PD-L1 expression by tumor cells by immunohistochemistry (IHC) (minimum of 50% of positive tumor cells is required for first-line setting, and of 1% for second-line and beyond) and PD-L1 assay is now considered as a companion diagnostic tool for this drug...

AIM: Tumors related to hereditary susceptibility seem to have an immunosensitive phenotype. MATERIALS & METHODS: We conducted a multicenter retrospective study, to investigate if family history of cancer, multiple neoplasms and early onset of cancer could be related to clinical outcomes of anti-PD-1/PD-L1 therapy. Activity and efficacy data of 211 advanced cancer patients (kidney, non-small-cell lung cancer, melanoma, urothelium, colorectal and HeN), treated at seven Italian centers with anti-PD-1/PD-L1 agents, were analyzed...

Immune therapy has now been incorporated into the standard of care for non-small-cell lung cancer based on randomized trials showing superiority of anti-PD1 antibodies compared with chemotherapy. Thus there is a renewed interest in immune approaches to treating lung cancer. One promising approach is with oncolytic viruses that either naturally or through engineering, preferentially infect or kill cancer cells. In preclinical models of different thoracic cancers, it has been found that these viruses can induce immune responses through multiple mechanisms...

INTRODUCTION: Classical therapeutic strategy for advanced and metastatic non-small cell lung cancer, without activable oncogenic driver mutation, has been based mainly on cytotoxic chemotherapy with modest benefits in terms of increased survival. BACKGROUND: A better understanding of the mechanisms involved in the regulation of the immune system led to the development of antibodies directed against immune checkpoints such as PD-L1. The first encouraging clinical data from phase I studies assessing anti-PD1 and anti-PD-L1 antibodies have been confirmed in randomised phase III trials...

Immunotherapy plays an important role in cancer treatment. Biomarkers that can predict response, including tumor-infiltrating lymphocytes (TILs), are in the spotlight of many studies. This cohort study was designed to evaluate the role of CD4+ and CD8+ TILs as predictive factors for response to anti PD-1 treatment in patients with metastatic non-small cell lung cancer (NSCLC) or metastatic melanoma. We evaluated the expression of CD4+ and CD8+ TILs in tissue samples of 56 patients with metastatic NSCLC or melanoma treated with anti-PD1 immunotherapy...

Although myeloid-derived suppressor cells (MDSCs) have been demonstrated to contribute to tumor initiation, progression and metastasis, however, which MDSC subsets are preferentially expanded and activated, and what's the key molecular mechanism responsible for specific MDSC subsets in promoting tumor progression need to be fully addressed. Here we identify that Ly6Gmi Ly6Clo CD11b+ CXCR2+ subpopulation (named CXCR2+ MDSCs) are predominately expanded and recruited in systemic and local tumor microenvironment during breast cancer progression and metastasis...

Expression of the multikinase inhibitor encoded by the tumor suppressor gene TUSC2 (also known as FUS1 ) is lost or decreased in non-small cell lung carcinoma (NSCLC). TUSC2 delivered systemically by nanovesicles has mediated tumor regression in clinical trials. Because of the role of TUSC2 in regulating immune cells, we assessed TUSC2 efficacy on antitumor immune responses alone and in combination with anti-PD-1 in two Kras -mutant syngeneic mouse lung cancer models. TUSC2 alone significantly reduced tumor growth and prolonged survival compared with anti-PD-1...

Backgrounds: EGFR-mutant non-small cell lung cancer (NSCLC) that developed acquired resistance to EGFR-tyrosine kinase (TKI) are potential candidates for programmed death 1 (PD1) inhibitor. Results: TPS≥1% for PD-L1 and low CD8 + TIL in post-TKI tumor showed a trend for a lower PFS of EGFR-TKIs (14.2 vs 9.9 months; P = 0.060) (cohort A). Only 2 of 22 specimens (9.1%) with an acquired EGFR exon 20 T790M mutation exhibited in post-TKI TPS≥50% for PD-L1. The degree in post-TKI tumor of PD-L1 expression was varied in 19 patients (40...

INTRODUCTION: Combined immune checkpoint blockade has led to rare autoimmune complications, such as fatal myocarditis. Recent approvals of several anti-PD1 drugs for lung cancer treatment prompted ongoing clinical trials that directly combine PD-1 inhibitors with thoracic radiotherapy for locally advanced lung cancer. Overlapping toxicities from either modality have the potential to increase the risk for radiation-induced cardiotoxicity (RICT), which is well documented among patients with HD and breast cancer...

Understanding the immune compartment of tumors facilitates the development of revolutionary new therapies. We used a Kras(G12D)-driven mouse model of lung cancer to establish an immune signature and identified a contribution of Gr1+ neutrophils to disease progression. Depletion experiments showed that Gr1+ cells (1) favor tumor growth, (2) reduce T cell homing and prevent successful anti-PD1 immunotherapy, and (3) alter angiogenesis, leading to hypoxia and sustained Snail expression in lung cancer cells. In turn, Snail accelerated disease progression and increased intratumoral Cxcl2 secretion and neutrophil infiltration...
