"immune checkpoint inhibitor"

BACKGROUND: The combination of CTLA-4 and PD-L1 inhibitors has a manageable adverse effect profile, although rare immune-related adverse events (irAE) can occur. CASE PRESENTATION: We describe an autoimmune polymyositis following a partial response to combination tremelimumab and durvalumab for the treatment of recurrent lung adenocarcinoma. Radiography revealed significant reduction in all metastases; however, the patient developed progressive neuromuscular hypoventilation due to lymphocytic destruction of the diaphragmatic musculature...

BACKGROUND: The B-raf gene is mutated in up to 66% of human malignant melanomas, and its protein product, BRAF kinase, is a key part of RAS-RAF-MEK-ERK (MAPK) pathway of cancer cell proliferation. BRAF-targeted therapy induces significant responses in the majority of patients, and the combination BRAF/MEK inhibitor enhances clinical efficacy, but the response to BRAF inhibitor and to BRAF/MEK inhibitor is short lived. On the other hand, treatment of melanoma with an immune checkpoint inhibitor, such as anti-PD-1, has lower response rate but the response is much more durable, lasting for years...

The anti-apoptotic cellular FLICE-like inhibitory protein cFLIP plays a pivotal role in normal tissues homoeostasis and the development of many tumors, but its role in normal thymus (NT), thymomas and thymic carcinomas (TC) is largely unknown.Expression, regulation and function of cFLIP were analyzed in biopsies of NT, thymomas, thymic squamous cell carcinomas (TSCC), thymic epithelial cells (TECs) derived thereof and in the TC line 1889c by qRT-PCR, western blot, shRNA techniques, and functional assays addressing survival, senescence and autophagy...

For the past decade, advanced renal cell carcinoma (RCC) has been at the forefront of oncologic innovation. Our rapidly evolving understanding of the molecular and genetic basis of RCC has revolutionized the management of advanced RCC; 10 novel molecular targeted agents and immune checkpoint inhibitor have received U.S. Food and Drug Administration approval for treatment of advanced RCC in a little over a decade. Amid this progress, imaging has assumed a central role in metastatic surveillance and follow-up of advanced RCC...

BACKGROUND: Studies combining immune checkpoint inhibitors with external beam radiation have shown a therapeutic advantage over each modality alone. The purpose of these works is to evaluate the potential of targeted delivery of high LET radiation to the tumor microenvironment via an immune checkpoint inhibitor. METHODS: The impact of protein concentration on the distribution of (111)In-DTPA-anti-PD-L1-BC, an (111)In-antibody conjugate targeted to PD-L1, was evaluated in an immunocompetent mouse model of breast cancer...

Modulation of T-cell activity through blockade of coinhibitory molecules has revolutionized the treatment of various malignancies. Several immune checkpoint inhibitors are currently Food and Drug Administration approved which target various coinhibitory pathways including cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed death 1 receptor (PD-1), and programmed cell death ligand-1. Clinical trials that lead to the Food and Drug Administration approval of these agents often excluded patients with an organ transplant...

Two types of immune checkpoint inhibitors, both antibodies that target cytotoxic T-lymphocyte antigen-4 and those that target programmed cell death-protein 1, have been approved for use in melanoma, non-small-cell lung cancer, and renal cell carcinoma as first-line or second-line therapy. Their adverse events are primarily regarded as immune-related adverse events. We felt it was important to pinpoint and discuss certain preconceptions or misconceptions regarding thyroid dysfunction, hypophysitis, and diabetes induced by immune checkpoint inhibitors...

The era of immune checkpoint inhibitors, especially programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) antibodies in the treatment of advanced non-small-cell lung cancer (NSCLC) is coming. Because of the lack of the definite biomarkers to select the optimal responders, only approximately 20% of patients with advanced NSCLC would respond to single checkpoint inhibitors-based immunotherapy. Moreover, primary or acquired resistance to conventional therapies is inevitable in most cases. Thus, combinations are pushed to move forward to be an alternative strategy and surely, it would be a future direction...

Unleashing the potential of immune system to fight cancer has become one of the main promising treatment modalities for advanced non-small cell lung cancer (NSCLC). The knowledge of numerous factors that come into play in the cancer-immunity cycle provide a wide range of potential therapeutic targets, including monoclonal antibodies that inhibits the programmed death-1 (PD-1) checkpoint pathway. Over the last two years, nivolumab, pembrolizumab and atezolizumab received approval for treatment of pretreated advanced NSCLC, and more recently, immunotherapy with pembrolizumab is the new standard of care as first-line in patients with high levels of programmed death-ligand 1 (PD-L1) expression...

The advent and success of immune checkpoint inhibitors (ICIs) in cancer treatment has broadened the spectrum of tumours that might be considered "immunogenic" and susceptible to immunotherapeutic (IT) intervention. Not all cancer types are sensitive, and not all patients with any given type respond. Combination treatment of ICIs with an established cytotoxic modality such as radiation therapy (RT) is a logical step towards improvement. For one, RT alone has been shown to be genuinely immunomodulatory and secondly pre-clinical data generally support combined ICI-RT approaches...

Treatment options for advanced and metastatic renal cell carcinoma have advanced considerably in the past decade with the approval of several targeted agents, including axitinib. Axitinib is a potent and selective inhibitor of VEGFRs 1-3, and is well established as second-line treatment. This article summarizes factors to be considered when administering axitinib, such as individualized dose titration and axitinib-associated adverse events, in order to retain patients longer on treatment, which would likely lead to improved efficacy outcomes...

Almost two-thirds of all new cancer diagnoses are made in persons over the age of 65 years, yet it is unclear if age affects patient responsiveness to immunotherapy, which is increasingly becoming first-line therapy in advanced stages of different tumor types. Preclinical animal studies may be difficult to translate into humans since they frequently use young mice (2-3 months of age) equivalent to adolescent human subjects. Nevertheless, ex vivo studies from humans are concordant with mice tissue findings-older patients have an increased density of circulating regulatory immune cells and a decreased ratio of naïve-to-memory T cells...

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...

Immune checkpoint inhibitors (ICI) are now a therapeutic option for advanced non-small cell lung cancer (NSCLC) patients. ICI, such as the PD-1 inhibitors nivolumab and pembrolizumab and the PD-L1 inhibitor atezolizumab, have already been marketed for the treatment of pretreated patients with advanced NSCLC. Other notable PD-L1 inhibitors under development include avelumab and durvalumab. Areas covered: This article reviews literature on durvalumab development, from the preclinical data to the results of phase III clinical trials, whether published or presented at international scientific conferences...

Pancreatic ductal adenocarcinoma (PDAC) is the third highest cause of cancer-related deaths in the US, and is projected to be second only to non-small cell lung cancer (NSCLC) by the 2020s. Current therapies have a modest impact on survival and median overall survival (mOS) across all stages of disease remains under a year. Over the last decade, however, great strides have been made in the understanding of PDAC pathobiology including the role of the tumor microenvironment (TME), DNA damage repair and mechanism of immunosuppression...

OBJECTIVES: Ipilimumab is the first licensed immune checkpoint inhibitor for treatment of melanoma. The promising results of the registration clinical study need confirmation in real practice and its clinical success comes together with a relevant budget impact due to the high price of this drug. The aim of this work is to describe a new model of economical sustainability of ipilimumab developed in an Italian reference center for melanoma treatment. METHODS: This retrospective, observational, and monocentric study was carried out at the Veneto Institute of Oncology...

Immune checkpoint inhibitors have recently emerged as an exciting new treatment paradigm across a broad spectrum of malignancies. This new class of agents also challenges oncologists with a unique set of immune-based toxicities. Early recognition and precise management of these toxicities can result in better outcomes, with minimization of toxicity and harm to the patient. This article provides a comprehensive review of immune-based toxicities caused by immune checkpoint inhibitors, including recommendations for their investigation and guidelines for specific management...

Soft tissue sarcoma(STS)is one of the rare and intractable cancers, and most types of STS are not sensitive to chemotherapy. Development of specific molecular target therapy for each type of STS is necessary. There are specific chromosome translocations in 20-30% of STS, but their products are mostly transcriptional factors, and target therapy for those factors are difficult to develop. Trabectedin is an alkylating agent and is also inhibit function of transcriptional factors, and shows efficacy for translocation-related sarcoma(TRS)such as myxoid liposarcoma...
