Effect Of Pd

Immune checkpoint blockade therapy is gaining popularity among oncologists for treatment of solid and hematologic malignancies. The widespread use of these agents resulted in increasing incidence of renal immune-related adverse events. Reported renal toxicity described so far includes acute interstitial nephritis, minimal change disease, and immune complex glomerulonephritis. We report the case of a 79-year-old female with metastatic non-small cell lung cancer on anti-PD-1 therapy nivolumab. After the 4th administration of nivolumab, the treatment course was complicated with normal anion gap metabolic acidosis. Urine and blood studies were in favor of distal renal tubular acidosis (RTA). Following a negative workup for an underlying etiology, immunotherapy-induced RTA was suspected. Withholding of the offending agent and initiation of steroid therapy resulted in adequate response. The present report provides the first presentation of RTA as a renal immune-related adverse event secondary to nivolumab. Nephrologists and oncologists should be familiar with potentially life-threatening renal side effects induced by immune checkpoint inhibitors.

Immunotherapy has become a mainstay therapeutic in a variety of malignancies. Checkpoint inhibitors are used to enhance the endogenous immune response to target malignancy. The primary targets of checkpoint inhibitors include programed cell death receptor 1 (PD-1), programed cell death ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4). Despite clinical benefits, immune checkpoint inhibitors are associated with side effects termed immune-related adverse events (irAEs). We report a case of the PD-1 inhibitor (pembrolizumab) causing severe distal renal tubular acidosis (RTA). The patient presented with altered mental status and was found to have a severe non-anion gap metabolic acidosis after other potential etiologies were ruled out. We review the etiology of immune checkpoint inhibitor-induced RTA and review the case reports that have been described in the literature.

Immune checkpoint inhibitors have opened a new era in treating advanced malignancies, resulting in a rapid increase in utilization, given the remarkable clinical outcomes. The incidence of immune-related adverse events increased due to the immunologic effects of these therapeutic agents. However, immune-related renal adverse events remain low, representing only a small incidence of reported cases. Common renal toxicity described includes acute interstitial nephritis, minimal change disease, and immune complex glomerulonephritis. Renal tubular acidosis has occasionally been reported but is highly uncommon. This report presents a case of a 68-year-old woman with a known history of metastatic melanoma undergoing treatment with ipilimumab+nivolumab, who developed distal renal tubular acidosis requiring stress dose steroids and sodium bicarbonate for treatment. We describe the clinical characteristics, potential mechanisms, and management of this case, highlighting the need among clinicians utilizing immune check inhibitors to be aware of this immune-related disease entity.

Skin Side Effects

Background:The introduction of Immune Checkpoint Inhibitors in the recent years has resulted in high response rates and extended survival in patients with metastatic/advanced malignancies. Their mechanism of action is the indirect activation of cytotoxic T-cells through the blockade of inhibitory receptors of immunomodulatory pathways, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Despite their impressive therapeutic results, they can also induce immune-related toxicity, affecting various organs, including the skin.Objective:To provide an updated summarized overview of the most common immune-mediated cutaneous side effects and their management.Method:English articles derived from the databases PubMed and SCOPUS and published between 2009 and 2018, were analyzed for this narrative review.Results:The most common adverse cutaneous reactions include maculopapular rash, lichenoid reactions, vitiligo and pruritus, with severity Grade 1 or 2. Less frequent but eventually life-threatening skin side effects, including Stevens-Johnson syndrome, Drug Reaction with Eosinophilia and Systemic Symptoms and Toxic Epidermal necrolysis, have also been reported.Conclusion:Basic knowledge of the Immune-Checkpoint-Inhibitors-induced skin toxicity is necessary in order to recognize these treatment-related complications. The most frequent skin side effects, such as maculopapular rash, vitiligo and pruritus, tend to subside under symptomatic treatment so that permanent discontinuation of therapy is not commonly necessary. In the case of life-threatening side effects, apart from the necessary symptomatic treatment, the immunotherapy should be permanently stopped. Information concerning the management of ICIs-mediated skin toxicity can be obtained from the literature as well as from the Summary of Product Characteristics of each agent.

Abstract Background Recent preclinical data suggest that there may be therapeutic synergy between immune checkpoint blockade and inhibition of the coagulation cascade. Here, we investigate whether patients who received immune checkpoint inhibitors (ICI) and were on concomitant anticoagulation (AC) experienced better treatment outcomes than individuals not on AC.Affiliation: Kindly confirm if corresponding authors affiliation is identified correctly.The corresponding author's affiliation is correct. Methods We studied a cohort of 728 advanced cancer patients who received 948 lines of ICI at NYU (2010–2020). Patients were classified based on whether they did (n = 120) or did not (n = 828) receive therapeutic AC at any point during their treatment with ICI. We investigated the relationship between AC status and multiple clinical endpoints including best overall response (BOR), objective response rate (ORR), disease control rate (DCR), progression free survival (PFS), overall survival (OS), and the incidence of bleeding complications.Affiliations: Journal instruction requires a country for affiliations; however, this is missing in affiliations 1 to 5. Please verify if the provided country is correct and amend if necessary.The country is correct for all affiliations (1 - 5). Results Treatment with AC was not associated with significantly different BOR (P = 0.80), ORR (P =0.60), DCR (P =0.77), PFS (P = 0.59), or OS (P =0.64). Patients who received AC were significantly more likely to suffer a major or clinically relevant minor bleed (P = 0.05). Conclusion AC does not appear to impact the activity or efficacy of ICI in advanced cancer patients. On the basis of our findings, we caution that there is insufficient evidence to support prospectively evaluating the combination of AC and immunotherapy.

Abstract Glioblastoma multiforme (GBM) is the most prevalent primary brain tumor endowed with a dismal prognosis. Nowadays, immunotherapy in a particular immune checkpoint blockade and therapeutic vaccines are being extensively pursued. Yet, several characteristics of GBM may impact such immunotherapeutic approaches. This includes tumor heterogeneity, the relatively low mutational load of primary GBM, insufficient delivery of antibodies to tumor parenchyma and the unique immunosuppressive microenvironment of GBM. Moreover, standard treatment of GBM, comprising temozolomide chemotherapy, radiotherapy and in most instances the application of glucocorticoids for management of brain edema, results in a further increased immunosuppression. This review will provide a brief introduction to the principles of vaccine-based immunotherapy and give an overview of the current clinical studies, which employed immune checkpoint inhibitors, oncolytic viruses-based vaccination, cell-based and peptide-based vaccines. Recent experiences as well as the latest developments are reviewed. Overcoming obstacles, which limit the induction and long-term immune response against GBM when using vaccination approaches, are necessary for the implementation of effective immunotherapy of GBM.

Checkpoint Blockade

The clinical success of immune checkpoint inhibitors has highlighted the central role of the immune system in cancer control. Immune checkpoint inhibitors can reinvigorate anti-cancer immunity and are now the standard of care in a number of malignancies. However, research on immune checkpoint blockade has largely been framed with the central dogma that checkpoint therapies intrinsically target the T cell, triggering the tumoricidal potential of the adaptive immune system. Although T cells undoubtedly remain a critical piece of the story, mounting evidence, reviewed herein, indicates that much of the efficacy of checkpoint therapies may be attributable to the innate immune system. Emerging research suggests that T cell-directed checkpoint antibodies such as anti-programmed cell death protein-1 (PD-1) or programmed death-ligand-1 (PD-L1) can impact innate immunity by both direct and indirect pathways, which may ultimately shape clinical efficacy. However, the mechanisms and impacts of these activities have yet to be fully elucidated, and checkpoint therapies have potentially beneficial and detrimental effects on innate antitumor immunity. Further research into the role of innate subsets during checkpoint blockade may be critical for developing combination therapies to help overcome checkpoint resistance. The potential of checkpoint therapies to amplify innate antitumor immunity represents a promising new field that can be translated into innovative immunotherapies for patients fighting refractory malignancies.

AbstractImmune checkpoint inhibitors (ICIs) are potent therapeutic options for many types of advanced cancer. The expansion of ICIs use however has led to an increase in immune-related adverse events (irAEs). Secondary adrenal insufficiency (AI) can be life-threatening especially in patients with delayed diagnosis. We retrospectively investigated secondary AI in ICI-treated patients. A total of 373 cancer patients treated with ICIs were included and evaluated. An adrenocorticotropic hormone (ACTH) deficiency was described in 13 patients. Among 24 patients with a combination of nivolumab and ipilimumab therapy, 7 patients (29%) developed secondary AI in a median time of 8 weeks during the combination therapy and 2 of 15 patients (13%) developed isolated ACTH deficiency during maintenance nivolumab monotherapy following the combination therapy. More than half of the patients (4/7) with a combination therapy-induced multiple anterior hormone deficiencies was diagnosed as secondary AI based on regular ACTH and cortisol tests with slight subjective symptoms. Secondary AI can arise frequently and rapidly in cancer patients receiving a combination ICI therapy, and thus we speculate active surveillance of AI using regular ACTH and cortisol tests during the combination therapy might be useful for avoiding life-threatening conditions due to secondary AI.

Immune checkpoint inhibitors (icis) such as inhibitors of ctla-4, PD-1, and PD-L1, given as monotherapy or combination therapy have emerged as effective treatment options for immune-sensitive solid tumours and hematologic malignancies. The benefits of icis can be offset by immune-related adverse events (iraes) that leave all organ systems vulnerable and subsequently increase the risk for morbidity and mortality.Because of fluctuating onset and prolonged duration, the toxicities associated with iraes represent a shift from the understanding of conventional anticancer toxicities. The ctla-4 and PD-1/PD-L1 inhibitors modulate T-cell response differently, resulting in distinct toxicity patterns, toxicity kinetics, and dose–toxicity relationships. Using individualized patient education, screening, and assessment for the early identification of iraes is key to proactive management and is therefore key to improving outcomes and prolonging therapy.Management of iraes is guided by appropriate grading, which sets the stage for the treatment setting (outpatient vs. inpatient), ici treatment course (delay vs. discontinuation), supportive care, corticosteroid use, organ specialist consultation, and additional immunosuppression. Health care professionals in oncology must work collaboratively with emergency and community colleagues to facilitate an understanding of iraes in an effort to optimize seamless care.

The use of immune checkpoint inhibitors has been approved in the advanced and metastatic setting for many types of solid tumors. Nonetheless, their role in the adjuvant setting is limited to the treatment of surgically resected melanoma. Ipilimumab was the first immune checkpoint inhibitor approved for this indication, followed by nivolumab and pembrolizumab. Many ongoing trials are evaluating these molecules in the postoperative setting, alone or in combination with other therapies. Preliminary results are promising regarding the treatment of other cutaneous tumors, lung cancers, head and neck squamous cell carcinomas, bladder cancer and renal cell carcinomas. Some data assessing their use for the adjuvant treatment of esophageal, colorectal, ovarian cancer and other solid tumors are similarly emerging.

Abstract Despite remarkable success of immune checkpoint inhibitors, the majority of cancer patients have yet to receive durable benefits. Here, in order to investigate the metabolic alterations in response to immune checkpoint blockade, we comprehensively profile serum metabolites in advanced melanoma and renal cell carcinoma patients treated with nivolumab, an antibody against programmed cell death protein 1 (PD1). We identify serum kynurenine/tryptophan ratio increases as an adaptive resistance mechanism associated with worse overall survival. This advocates for patient stratification and metabolic monitoring in immunotherapy clinical trials including those combining PD1 blockade with indoleamine 2,3-dioxygenase/tryptophan 2,3-dioxygenase   (IDO/TDO) inhibitors.
