BackgroundLong-term survival is still low for high-risk patients with soft tissue sarcoma treated with standard management options, including surgery, radiation, and chemotherapy. Immunotherapy is a promising new potential treatment paradigm. However, the application of immune checkpoint inhibitors for the treatment of patients with sarcoma did not yield promising results in a clinical trial. Therefore, there is a considerable need to identify factors that may lead to immune checkpoint inhibitor resistance.MethodsIn this study, we performed a bioinformatic analysis of The Cancer Genome Atlas (TCGA) to detect key long noncoding RNAs (lncRNAs) that were correlated with immune checkpoint inhibitory molecules in sarcoma. The expression levels of these lncRNAs and their correlation with patient prognosis were explored. The upstream long noncoding RNAs were also examined via 450K array data from the TCGA. The potential roles of these lncRNAs were further examined via KEGG and GO analysis using DAVID online software. Finally, the relationship between these lncRNAs and immune cell infiltration in tumors and their effect on immune checkpoint inhibitors were further explored.ResultsWe identified lncRNAs correlated with tumor cell immune evasion in sarcoma. The expression of these lncRNAs was upregulated and correlated with worse prognosis in sarcoma and other human cancer types. Moreover, low DNA methylation occupation of these lncRNA loci was detected. Negative correlations between DNA methylation and lncRNA expression were also found in sarcoma and other human cancer types. KEGG and GO analyses indicated that these lncRNAs correlated with immune evasion and negative regulation of the immune response in sarcoma. Finally, high expression of these lncRNAs correlated with more suppressive immune cell infiltration and reduced sensitivity to immune checkpoint inhibitors in sarcoma and other human cancer types.ConclusionOur results suggest that long noncoding RNAs confer immune checkpoint inhibitor resistance in human cancer. Further characterization of these lncRNAs may help to elucidate the mechanisms underlying immune checkpoint inhibitor resistance and uncover a novel therapeutic intervention point for immunotherapy.

Immune checkpoint inhibitors are novel agents that have been proved efficacious in a variety of cancer types, but they are associated with a unique set of organ-specific, immune-related adverse events. Among them, immune-related pneumonitis requires special attention because it is difficult to diagnose and potentially lethal. Accumulating real-world epidemiological data suggest that immune-related pneumonitis is more frequent than previously reported. Its diagnosis requires exclusion of other causes and assessment of radiographic features on high-resolution CT of the chest. Management of immune-related pneumonitis is based on the use of immunosuppressants. Future research should be focused on finding predictive biomarkers for immune-related pneumonitis as well as optimizing its management.

e16194 Background: Hepatocholangiocarcinoma (HCC-CC) is a rare form of cancer with a poor prognosis. Of all primary liver cancers, the incidence of HCC-CC ranges from 0.4 to 14.2%. HCC-CC is a mixed carcinoma with findings of both hepatocellular carcinoma and cholangiocarcinoma. Immune checkpoint inhibitors are a potent first line treatment in hepatocellular carcinoma with multiple clinical trial showing effectiveness in cholangiocarcinoma. HCC-CC has limited proven treatment options as patients are generally excluded from clinical trials. In this study we reviewed outcomes of patients with HCC-CC who received immune checkpoint inhibitor in a single center. Methods: Records of patients who had a pathological confirmed HCC-CC by a subspecialized hepatic pathologist at the University of Kansas medical center were reviewed. We identified 6 patients with locally advanced unresectable or metastatic HCC-CC that received immune checkpoint inhibitor between February 2017 and January 2021. Baseline characteristics were obtained, as well as best response, line of therapy, and duration of response. Results: Of the six patients 4 (66%) received PD-1 inhibitor alone and 2 (34%) received combination therapy with CTLA-4 inhibitor for the treatment of HCC-CC. There were 3 (50%) females and 6 (100%) with prior hepatitis C infection. four (66%) patients had metastatic disease and 2 had locally unresectable advanced disease. Objective response rate was 83.3%. One patient achieved complete response and had a treatment holiday after receiving treatment for 2 years, and restarted immunotherapy upon relapse. Four patients had a partial response, of which two passed away after disease progression. One patient had stable disease on 2 different lines of immunotherapy then progressed. Of those who responded, one patient received immunotherapy, 3 (50%) received liver directed therapy and two received chemotherapy or Lenvatinib as first line treatment (Table). Conclusions: Immune checkpoint inhibitors demonstrate potential activity in patients with HCC-CC without unexpected side effect in this unmet need high-risk population. Larger studies are needed to confirm activity and efficacy in this setting.[Table: see text]

Introduction The development of immune checkpoint inhibitors has revolutionized cancer treatment and is now a part of the treatment paradigm for several malignancies. Although immune checkpoint inhibitors are generally well tolerated, treatment is associated with immune-related adverse events, some serious and potentially life threatening. Early identification and prompt appropriate management of immune-related adverse events are crucial to prevent morbidity and mortality. The complexity and severity of immune-related adverse events require interdisciplinary collaboration to optimize care. Patient and caregiver education and continued communication between patients and members of the oncology care team are vital for timely recognition and successful management of immune-related adverse events. The objective of this program is to provide a proof of concept; a pharmacist-led immune checkpoint inhibitor management program will increase early recognition and management of immune-related adverse events through patient and caregiver education and proactively assessing patients for toxicities. Methods At the University of Wisconsin Carbone Cancer Center, we developed and implemented a pharmacist-driven program, referred to as the immune checkpoint inhibitor program, which aimed to ensure patient and caregiver education and continuous monitoring of immune-related adverse events. This program utilized pharmacist–patient encounters to improve patient and caregiver education and follow-up monitoring. The design and implementation are detailed. Pharmacist interventions and patient outcomes were evaluated. Results At interim analysis, 47 patients were enrolled in the program and pharmacists completed 34 interventions on 26 patients. Pharmacists are well positioned to educate patients and caregivers on immune checkpoint inhibitor therapy and provide proactive monitoring to detect immune-related adverse events. We hypothesize that the interventions made by pharmacist may lead to earlier recognition and treatment of immune-related adverse events.

Immune checkpoint inhibitors successfully treat various malignancies by inducing an immune response to tumor cells. However, their use has been associated with a variety of autoimmune disorders, such as diabetes, hepatitis, and pneumonitis. Pulmonary arterial hypertension due to checkpoint inhibitor use has not yet been described. We present a novel case of pulmonary arterial hypertension associated with systemic lupus erythematosus and Sjogren’s syndrome overlap that was induced by therapy with the checkpoint inhibitor durvalumab.

Abstract Immune checkpoint inhibitors (CPIs) have recently become a cornerstone for the treatment of different advanced cancers. These drugs have the ability to reactivate the immune system against tumour cells but can also trigger a myriad of side effects, termed immune-related adverse events (irAEs). Although there are numerous reports of CPI-related endocrinopathies, hypercalcaemia as a suspected irAE is not well documented. The mechanisms of CPI hypercalcaemia are not clearly established. However, in our review, four distinct causes emerged: endocrine disease-related, sarcoid-like granuloma, humoral hypercalcaemia due to parathyroid-related hormone and hyperprogressive disease following CPI initiation. Prompt recognition of hypercalcaemia and the institution of therapy can be lifesaving, affording the opportunity to address the underlying aetiology. In this review we discuss the incidence, diagnosis and management of immune-related hypercalcaemia in oncological patients receiving CPI agents.

The Body

Background: Immune checkpoint inhibitors have changed the therapeutic milieu for patients with metastatic melanoma. However, their use may promote autoimmunity in virtually any organ in the body due to the blockade of intrinsic immune down regulators such as cytotoxic T-lymphocyte antigen- 4 (CTLA-4), programmed cell death 1 (PD1) or its ligand (PDL1). Immune mediated adverse neurological events are rare with these agents, however, and are seen in < 1% of treated patients. We report a patient with immune checkpoint inhibitor associated autoimmune encephalitis, with complete clinical recovery after treatment.Case Report: A 49-year-old female with metastatic melanoma currently on nivolumab therapy but recently on ipilimumab/nivolumab combined therapy presented with a new headache. She also reported associated confusion, loss of balance, personality changes and language difficulty. Magnetic resonance imaging of the brain did not reveal any evidence of metastasis, infarct, meningitis, or encephalitis. Lumbar puncture revealed an elevated protein level and pleocytosis, with a normal glucose level. She was started on empiric glucocorticoid therapy with a presumptive diagnosis of immune checkpoint inhibitor associated autoimmune encephalitis. She improved considerably by day 3 of treatment with complete resolution of neurological symptoms by day 5.Conclusion: Immune checkpoint inhibitors are increasingly important in cancer immunotherapy as they can cause sustained remissions in patients with metastatic melanoma and other malignancies. Because these drugs block immune-regulatory targets, they can lead to enhanced activation of immune system resulting in immune-related adverse events. Autoimmune encephalitis is a rare immune-related adverse event associated with immune checkpoint inhibitors. The incidence of autoimmune encephalitis is higher with combination or sequential CTLA-4 (ipilimumab) and PD1(nivolumab) inhibitor therapy than with monotherapy. With more widespread use of immunotherapy, it is important for clinicians to be aware of this rare and reversible cause of encephalitis. Early recognition and prompt initiation of immunosuppressive therapy with glucocorticoids is essential to enhance neurological recovery.

Background: Immune checkpoint inhibitors have changed the landscape of cancer care by increasing progression-free and overall survival in some patients with cancer. We evaluated use and variables contributing to immune checkpoint inhibitor treatment near the end of life. Methods: We studied 157 patients who received immune checkpoint inhibitors and died between January 2015 and December 2018. All patients had a palliative care consult any time between starting an immune checkpoint inhibitor and death. Univariate and multivariate models were used to examine variables related to immune checkpoint inhibitor use near the end of life. Results: Among 157 patients studied, 42 (27%) received a dose of immune checkpoint inhibitor in the last 30 days of life. Those who received treatment in the last 30 days of life had lower hospice enrollment (19 [45%] vs 78 [69%], P = .007) and higher rates of dying in the hospital (23 [56%] vs 33 [29%], P = .002). The percentage of patients with Eastern Cooperative Oncology Group (ECOG) ≥3 at the time of last immune checkpoint inhibitor dose was higher in the group that received immune checkpoint inhibitor treatment in the last 30 days of life (11 [26%] vs 9 [8%], P = .003). Lack of traditional chemotherapy after immune checkpoint inhibitor, ECOG ≥3, and lack of hospice enrollment were independently associated with receiving immune checkpoint inhibitor in the last 30 days of life. Conclusion: Immune checkpoint inhibitor use in the last 30 days of life is common and associated with poor performance status, lower hospice enrollment, and dying in the hospital.

AbstractBackgroundWhile immune checkpoint inhibitors are becoming a standard of care for multiple types of cancer, the majority of patients do not respond to this form of immunotherapy. New approaches are required overcome resistance to immunotherapies.MethodsWe investigated the effects of adenoviral p53 (Ad-p53) gene therapy in combination with immune checkpoint inhibitors and selective IL2 or IL15 CD122/132 agonists in the aggressive B16F10 tumor model resistant to immunotherapies. To assess potential mechanisms action, pre and post Ad-p53 treatment biopsies were evaluated for changes in gene expression profiles by Nanostring IO 360 assays.ResultsSubstantial synergy of “triplet” Ad-p53 + CD122/132 + anti-PD-1 therapy resulted in potential curative effects associated with complete tumor remissions of both primary and contralateral tumors. Interestingly, contralateral tumors which were not injected with Ad-p53 showed robust abscopal effects resulting in statistically significant decreases in tumor size and increased survival (p<0.001). None of the monotherapies or doublet treatments induced complete tumor regressions. Ad-p53 treatment increased Type I Interferon, CD8+ T cell, immuno-proteosome antigen presentation and tumor inflammation gene signatures. Ad-p53 treatment also decreased immune suppressive TGF-beta, beta-catenin, macrophage, and endothelium gene signatures, which may contribute to enhanced immune checkpoint inhibitor (CPI) efficacy. Unexpectedly, a number of previously unidentified, strongly p53 down regulated genes associated with stromal pathways and IL10 expression identified novel anti-cancer therapeutic applications.ConclusionsThese results imply the ability of Ad-p53 to induce efficacious local and systemic anti-tumor immune responses with the potential to reverse resistance to immune checkpoint inhibitor therapy when combined with CD122/132 agonists and immune checkpoint blockade. Our findings further imply that Ad-p53 has multiple complimentary immune mechanisms of action which support future clinical evaluation of triplet Ad-p53, CD122/132 agonist and immune checkpoint inhibitor combination treatment.

Treatment with immune checkpoint inhibitors has shown efficacy against a variety of cancer types. The effects of nivolumab and pembrolizumab on lung cancer have been reported, and further therapeutic advances are ongoing. The side effects of immune checkpoint inhibitors are very different from those of conventional cytocidal anticancer drugs and molecular targeted drugs, and they involve various organs such as the digestive and respiratory organs, thyroid and pituitary glands, and skin. The generic term for such adverse events is immune-related adverse events (irAEs). They are relatively infrequent, and, if mild, treatment with immune checkpoint inhibitors can be continued with careful control. However, early detection and appropriate treatment are critical, as moderate-to-severe irAEs are associated with markedly reduced organ function and quality of life, with fatal consequences in some cases. Of these, endocrinopathies caused by immune checkpoint inhibitors are sometimes difficult to distinguish from nonspecific symptoms in patients with advanced cancer and may have serious outcomes when the diagnosis is delayed. Therefore, it is necessary to anticipate and appropriately address the onset of endocrinopathies during treatment with immune checkpoint inhibitors. Here, we present a review of endocrine disorders caused by immune checkpoint inhibitor treatment.
