The immune system can restrain or promote cancer development and growth. Antibodies targeting immune checkpoints have revolutionized cancer treatment. Among the best responses have been in non-small cell lung cancer (NSCLC) which is largely caused by chronic exposure to carcinogens; associated with high neoantigen creation and sensitization to immune recognition. Atezolizumab was the first approved antibody that targets the PD-1 ligand (PD-L1). Areas Covered: This drug profile article covers the basics of the cancer-immunity cycle and reviews some aspects of innate and adaptive immunology...

Immune checkpoint inhibitors, a new class of cancer therapeutic agents, play an important role in the management of melanoma, NSCLC, and other malignancies. A workshop organized by three MASCC Study Groups: Oral Care, Skin Toxicities, and Neutropenia, Infection, and Myelosuppression during the MASCC Annual Meeting held in Adelaide, Australia on 23-25 June, 2016 focused on the new class of anti-cancer therapeutic agents. Topics in the workshop included the mechanism of action and clinical uses of immune anti-CTL4 and anti-PD1 antibodies, checkpoint inhibitor toxicities, including skin adverse events, gastrointestinal toxicities, oral complications, pulmonary toxicities, and endocrinological and immune-related infections...

Importance: New targeted therapies for cancer have been released in recent years, opening new horizons in the treatment of patients with cancer. However, their related adverse events (AE) are not fully characterized. Hair repigmentation (HR) is a nondescribed effect secondary to anti-programmed cell death 1 (anti-PD-1) and anti-programmed cell death ligand 1 (anti-PD-L1 ) therapy for treatment of lung cancer (LC), in opposition to the vitiligo reactions that develop during melanoma treatment...

Developments of EGFR-TKI and immunotherapy targeting the PD1/PD-L1 pathway are considered most important medical breakthroughs in lung cancer treatment. Nowadays, 3rd generation EGFR TKI is widely used for T790M positive 1st and 2nd EGFR-TKI resistant lung cancer patients. Immunotherapy is powerful option for lung cancer patients without drug targets and chemotherapy resistant patients. It also has changed the concept of conventional anti-cancer therapy in the point of regulating tumor microenvironment. There are many studies linking these two important pathways...

Lung sarcomatoid carcinoma of the lung is a rare tumor with a poor prognosis. More than 90% of them are pleomorphic, spindle cell and giant cell carcinoma (PSCGCC). This rare subtype of lung cancer is thought to be more resistant to chemotherapy, and a small subset of them seems to exhibit targetable mutations. Immunotherapy against PD1/PDL-1 is a new emerging treatment, and might be of interest in PSGSCC because they frequently express PD-L1. The aim of our work is to evaluate PD1 and PDL-1 expression in a surgical series of lung PSCGCC and their relationship with morphological and immunohistochemical parameters and prognosis...

Immunotherapy renews in non-small cell lung cancer. Antibodies directed against PD1 and PD-L1, blocking the relationship between the cancer cells and the immune system, allowed in randomised trials to significantly improve cancer control with an interesting survival impact of treated patients. However, it remains to determine the most benefiting populations from this expensive and potentially toxic therapy.

Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC...

INTRODUCTION: PD-L1 is established as a predictive marker for therapy of non-small cell lung cancer with pembrolizumab. Furthermore, PD-L1 positive melanoma has shown more favorable outcomes when treated with anti-PD1 antibodies and dacarbazine compared to PD-L1 negative melanoma. However, the role of PD-L1 expression with regard to response to checkpoint inhibition with anti-CTLA-4 is not clear, yet. In addition, the lack of standardization in the immunohistochemical assessment of PD-L1 makes the comparison of results difficult...

Despite recent advances with targeted kinase inhibitors and better tolerated chemotherapy, the treatment of metastatic non-small cell lung cancer (NSCLC) remains suboptimal. One recent advance that holds great promise is immunotherapy - an approach that enhances a patient's immune system to better recognize and react to abnormal cells. The most successful immunotherapeutic strategy to date uses antibodies to block inhibitory receptors (also called "checkpoints") that are upregulated on the T cells that infiltrate the tumor...

We reported a case of relapsing immune-related colitis (initially caused by nivolumab) following osimertinib therapy for lung adenocarcinoma. A 45-year-old female who had never smoked was diagnosed with adenocarcinoma of the lung and underwent surgical resection. Four years after surgical resection, she was diagnosed with recurrent disease and was eventually treated with nivolumab as third-line therapy. One month after the completion of nivolumab therapy, the patient reported abdominal pain and frequent diarrhea...

Immunotherapies have changed the treatment strategy of some types of tumor including melanoma and, more recently, non-small-cell lung cancer (NSCLC). Immune checkpoints are crucial for the maintenance of self-tolerance and it is known that some tumors use checkpoint systems to evade antitumor immune response. The treatment of advanced NSCLC by immune-checkpoint blockade targeting the PD1/PDL1 and CTLA4 pathways has led to significant clinical benefit either as monotherapy or in combination therapy. Moreover, checkpoint receptors such as LAG3, TIM3 and KIRs are also being investigated as potential immunotherapeutic targets...

Programmed cell death-1 protein (PD-1) is an immune checkpoint that has gained popularity in the treatment of several advanced cancers. Inhibiting this checkpoint is known to enhance immune response, but is also known to diminish immune tolerance and to increase autoimmune toxicity. We discuss a case of rapid onset fulminant Type 1 diabetes induced by treatment with anti-programmed cell death-1 monoclonal antibody, nivolumab, in a patient with late-stage non-small-cell lung adenocarcinoma. The patient had no history of previous diabetes but did reveal a high-risk genotype for Type 1 diabetes development (DR3-DQ2; DR4-DQ8)...

The study of immunology has led to breakthroughs in treating non-small cell lung cancer (NSCLC). The recent approval of an anti-PD1 checkpoint drug for NSCLC has generated much interest in novel combination therapies that might provide further benefit for patients. However, a better understanding of which combinations may (or may not) work in NSCLC requires understanding the lung immune microenvironment under homeostatic conditions and the changes in that microenvironment in the setting of cancer progression and with radiotherapy...

Glioblastoma (GBM) is resistant to most multimodal therapies. Clinical success of immune-checkpoint inhibitors (ICIs) has spurred interest in applying ICIs targeting CTLA4, PD1 or IDO1 against GBM. This amplifies the need to ascertain GBM's intrinsic susceptibility (or resistance) toward these ICIs, through clinical biomarkers that may also "guide and prioritize" preclinical testing. Here, we interrogated the TCGA and/or REMBRANDT human patient-cohorts to predict GBM's predisposition toward ICIs. We exploited various broad clinical biomarkers, including mutational or predicted-neoantigen burden, pre-existing or basal levels of tumor-infiltrating T lymphocytes (TILs), differential expression of immune-checkpoints within the tumor and their correlation with particular TILs/Treg-associated functional signature and prognostic impact of differential immune-checkpoint expression...

Targeting checkpoint inhibitors using monoclonal antibodies results in significantly better outcome of cancer patients compared to conventional chemotherapy. However, the current companion diagnostics to predict response is so far suboptimal, since they base on more or less reliable immunohistochemical approaches. In order to overcome these limitations, we analyzed epigenetic modifications of PDCD1 (PD1), CD274 (PD-L1), and CTLA4 in NSCLC tissues from 39 patients. Results were correlated with transcriptome data...

Antibody targeting of the immune checkpoint receptor PD1 produces therapeutic activity in a variety of solid tumors, but most patients exhibit partial or complete resistance to treatment for reasons that are unclear. In this study, we evaluated tumor specimens from 65 patients with melanoma, lung nonsquamous, squamous cell lung or head and neck cancers who were treated with the approved PD1-targeting antibodies pembrolizumab or nivolumab. Tumor RNA before anti-PD1 therapy was analyzed on the nCounter system using the PanCancer 730-Immune Panel, and we identified 23 immune-related genes or signatures linked to response and progression-free survival (PFS)...

BackgroundRecent clinical results support the use of new immune checkpoint blockers (ICB), such as anti-PD-1 (e.g. nivolumab, pembrolizumab) and anti-PD-L1 antibodies. Radiological evaluation of ICB efficacy during therapy is challenging due to tumor immune infiltration. Changes of circulating tumor DNA (ctDNA) levels during therapy could be a promising tool for very accurate monitoring of treatment efficacy, but data are lacking with ICB.Patients and methodsThis prospective pilot study was conducted in patients with non-small cell lung cancer, uveal melanoma or microsatellite-instable colorectal cancer treated by nivolumab or pembrolizumab monotherapy at Institut Curie...

Immune checkpoint inhibitors (ICIs) are antibodies that target key signalling pathways such as programmed death 1 (PD1)/programmed death-ligands 1 and 2 (PDL1 and PDL2) to improve anti-tumour immune responses. Until recently, nivolumab was the only ICI validated for advanced non-small-cell lung cancer (NSCLC) in a second-line treatment setting. Results from recent phase II and phase III randomised trials testing other ICIs have been presented. In Keynote-024, pembrolizumab, an anti-PD1 antibody, was reported to have great efficacy in the first-line treatment of PDL1 ≥ 50% tumours (30% of screened tumours), with a progression-free survival (PFS, median) of 10...

Salivary gland carcinomas are rare tumours and therapy strategies are less standardized than in lung, gastric or breast cancer. Therapy is based on surgery, but not all carcinomas are completely resectable, e.g. because carcinomas often show infiltration of nerves. For further therapy decision pathology is recommended, but evaluation of potential targets for personalized therapy is not part of the routine panel. Many salivary gland carcinomas can be resistant to radio- and/or chemotherapy, which limits therapeutic options...
