PURPOSE: Non-small-cell lung cancer (NSCLC) has a large worldwide prevalence with a high mortality rate. Chemotherapy has offered modest improvements in survival over the past two decades. Immune checkpoint modulation with programmed death-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibition has shown the promise of changing the future landscape of cancer therapy. This update reviews recent advances in the treatment of NSCLC with immune checkpoint modulation. METHODS: Publications and proceedings were identified from searching PubMed and proceedings from the annual meetings of the American Society of Clinical Oncology, European Society for Medical Oncology, and European Lung Cancer Conference...

BACKGROUND: Myelophthisis due to melanoma is a rare phenomenon. Treatment strategies for patients with this serious complication of malignancy have not been well documented, and none have previously reported efficacy of immune checkpoint inhibition. Since bone metastases are not measurable lesions per standard response criteria, the efficacy of immune checkpoint inhibition in the bones is also not well described. CASE PRESENTATION: We describe a patient with widespread melanoma metastases involving the bone marrow causing myelophthisis and pancytopenia who responded to immune checkpoint inhibition with the anti-programmed cell death-1 (PD-1) inhibitor pembrolizumab...

Background: Treatment with immune checkpoint inhibitors (ICPi) has greatly improved survival for patients with advanced melanoma in recent years. Anti-CTLA-4 and anti-PD1 antibodies have been approved following large Phase III trials. Immune-related neurological toxicity of varying severity has been reported in the literature. The cumulative incidence of neurotoxicity among ipilimumab, nivolumab and pembrolizumab is reported as <1% in published clinical trials. We aimed to identify the incidence of neurotoxicity in our institution across anti-CTLA4 and anti-PD-1 antibodies, including the combination of ipilimumab with nivolumab...

Ipilimumab, nivolumab, and pembrolizumab represent a new class of immunotherapeutic drugs for treating patients with advanced cancer. Known as checkpoint inhibitors, these drugs act to upregulate the cellular and humoral immune response to tumor antigens by inhibiting T-cell autoregulation. As a consequence, they can be associated with immune-related adverse events (irAEs) due to loss of self-tolerance, including rare cases of immune-related cytopenias. We performed a retrospective clinical chart review, including serologic, hematology, and chemistry laboratory results, of two patients who developed red blood cell (RBC) autoantibodies during treatment with a checkpoint inhibitor...

CLL patients progressed early on ibrutinib often develop Richter's transformation (RT) with short survival about 4 months. Preclinical studies suggest that programmed death 1 (PD-1) pathway is critical to inhibit immune surveillance in CLL. This phase 2 study MC1485 (NCT02332980) was designed to test the efficacy and safety of pembrolizumab, a humanized PD-1-blocking antibody, at a dose of 200 mg every 3 weeks in relapsed and transformed CLL. Twenty-five patients including 16 relapsed CLL and 9 RT (all proven diffuse large cell lymphoma) patients were enrolled and 60% received prior ibrutinib...

Background: HASH(0x3a81db8) Pembrolizumab and nivolumab are immune checkpoint inhibitors targeting PD-1 that have recently been approved in pretreated recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC) patients. In the clinic, some patients seem not only not to benefit from anti-PD-L1/PD-1 agents but rather to experience an acceleration of tumor growth kinetics (TGK). Patients and Methods: HASH(0x3f54670) We retrospectively compared TGK on immunotherapy and TGK on last treatment in patients with R/M HNSCC treated with PD-1/PD-L1 inhibitors in four French centers...

Systemic adjuvant therapy for surgically resected cutaneous melanoma that is at high risk for disease recurrence and death targets residual micrometastatic disease which is the source of future local or distant relapse. Interferon-alfa (IFNα) has been the most extensively studied in regimens that varied by dosage, route of administration, formulation, and duration of therapy. Most regimens have demonstrated improvements in relapse-free survival (RFS), while the regimen administered at high dosage (HDI) showed improvements in overall survival (OS) in two out of three RCTs...

Second-line treatment options are limited for patients with advanced non-small-cell lung cancer (NSCLC). Standard therapy includes the cytotoxic agents docetaxel and pemetrexed, and the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors erlotinib and gefitinib. Immune checkpoint inhibitors are a new class of treatment that have shown durable overall radiologic response rates and have been well tolerated. The objective of this systematic review was to investigate the efficacy of immune checkpoint inhibitors compared with other chemotherapies in patients with advanced NSCLC...

We explored the association between liver metastases, tumor CD8+ T cell count, and response in patients with melanoma or lung cancer treated with the anti-PD-1 antibody, pembrolizumab. The melanoma discovery cohort was drawn from the Phase I Keynote 001 trial, whereas the melanoma validation cohort was drawn from Keynote 002, 006, and EAP trials and the non-small cell lung cancer (NSCLC) cohort from Keynote 001. Liver metastasis was associated with reduced response and shortened progression-free survival (PFS); [objective response rate (ORR), 30...

Based on the positive results of various clinical trials, treatment options for non-small cell lung cancer (NSCLC) have expanded greatly over the last 25 years. While regulatory approvals of chemotherapeutic agents for NSCLC have largely been based on improvements in overall survival, recent approvals of many targeted agents for NSCLC (afatinib, crizotinib, ceritinib, osimertinib) have been based on surrogate endpoints such as progression-free survival and objective response. As such, selection of appropriate clinical endpoints for examining the efficacy of investigational agents for NSCLC is of vital importance in clinical trial design...

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...

The optimal sequencing of targeted treatment and immunotherapy in the treatment of advanced melanoma is a key question and prospective studies to address this are ongoing. Previous observations suggest that treating first with targeted therapy may select for more aggressive disease, meaning that patients may not gain full benefit from subsequent immunotherapy. In a single-center retrospective analysis, we investigated whether response to pembrolizumab was affected by previous BRAF inhibitor therapy. A total of 42 patients with metastatic cutaneous or mucosal melanoma who had received previous treatment with ipilimumab were treated with pembrolizumab as part of the Italian expanded access program...

This selection from the NCCN Guidelines for Non-Small Cell Lung Cancer (NSCLC) focuses on targeted therapies and immunotherapies for metastatic NSCLC, because therapeutic recommendations are rapidly changing for metastatic disease. For example, new recommendations were added for atezolizumab, ceritinib, osimertinib, and pembrolizumab for the 2017 updates.

Although survival of patients with different types of cancer has improved, cardiotoxicity induced by anti-neoplastic drugs remains a critical issue. Cardiac dysfunction after treatment with anthracyclines has historically been a major problem. However, also targeted therapies and biological molecules can induce reversible and irreversible cardiac dysfunction. Cancer immunotherapies over the last years have revolutionized the clinical management of a wide spectrum of solid and hematopoietic malignancies previously endowed with poor prognosis...

No definitive cure is known for recurrent, persistent or metastatic cervical carcinoma. Chemotherapy remains the standard of care, although available options are scarce and do not provide satisfactory results. Immune checkpoint inhibitors have shown a strong and prolonged response in several types of cancer, although only in a subset of patients. Defining the profile of the patients likely to benefit from such treatment is a subject of active research. Here, we present a case of a heavily pretreated patient with recurrent advanced squamous cell carcinoma of the cervix who had exhausted all available treatment options and showed a striking response to the immune checkpoint inhibitor pembrolizumab...

Despite the success of monotherapies based on blockade of programmed cell death 1 (PD-1) in human melanoma, most patients do not experience durable clinical benefit. Pre-existing T-cell infiltration and/or the presence of PD-L1 in tumours may be used as indicators of clinical response; however, blood-based profiling to understand the mechanisms of PD-1 blockade has not been widely explored. Here we use immune profiling of peripheral blood from patients with stage IV melanoma before and after treatment with the PD-1-targeting antibody pembrolizumab and identify pharmacodynamic changes in circulating exhausted-phenotype CD8 T cells (Tex cells)...

Little is known on factors predicting toxicity of anti-PD1 checkpoint inhibitors. Sarcopenic obesity is associated with increased acute toxicity of cytotoxic agents and targeted therapies. We explored whether body composition also influenced the occurrence of early acute limiting toxicity (ALT) of anti-PD1 in melanoma patients. This is a monocentric, retrospective study analyzing toxicity outcome in consecutive melanoma patients treated with nivolumab or pembrolizumab. Various parameters linked to the patient or the disease status have been analysed...

Cutaneous melanoma is a highly aggressive tumor developing from melanocytes, its incidence is increasing, and prognosis in advanced stages is daunting. New therapies have been approved during the recent years with unprecedented results, including inhibitors of MAPK/ERK pathway and immune checkpoint blockade (anti-cytotoxic T lymphocyte antigen-4 (CTLA-4) as ipilimumab, anti-programmed cell death protein 1 (PD-L1) as pembrolizumab and anti-programmed cell death protein 1 ligand (PD-L1), among many others). The aim of this paper is to review currently available metastatic melanoma therapies focusing mainly on new therapies that have demonstrated effectiveness, after several decades of little progress in the treatment of this disease...

In recent years, new drugs have been designed for treating advanced cutaneous malignant melanoma, in particular the metastases. They afford modest benefits despite the fact they are commonly heralded as breakthroughs in the lay press and by some medical opinion leaders. Unfortunately, the use of inflated descriptors of the drug efficacy leads to misunderstandings among the clinicians in charge of patients. Currently, vemurafenib, ipilimumab, pembrolizumab and nivolumab have demonstrated their relative activity in the control of advanced malignant melanoma...
