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.

Immune Checkpoints

The immune system is known to help fight cancers. Ten years ago, the first immune checkpoint inhibitor targeting CTLA4 was approved by the FDA to treat patients with metastatic melanoma. Since then, immune checkpoint therapies have revolutionized the field of oncology and the treatment of cancer patients. Numerous immune checkpoint inhibitors have been developed and tested, alone or in combination with other treatments, in melanoma and other cancers, with overall clear benefits to patient outcomes. However, many patients fail to respond or develop resistance to these treatments. It is therefore essential to decipher the mechanisms of action of immune checkpoints and to understand how immune cells are affected by signaling to be able to understand and overcome resistance. In this review, we discuss the signaling and effects of each immune checkpoint on different immune cells and their biological and clinical relevance. Restoring the functionality of T cells and their coordination with other immune cells is necessary to overcome resistance and help design new clinical immunotherapy strategies. In this respect, NK cells have recently been implicated in the resistance to anti-PD1 evoked by a protein secreted by melanoma, ITGBL1. The complexity of this network will have to be considered to improve the efficiency of future immunotherapies and may lead to the discovery of new immune checkpoints.

Significant Research

Autoimmune myocarditis is a rare, but frequently fatal, side-effect of immune checkpoint inhibitors (ICIs), a class of drugs used to treat cancer. Due to the overwhelming complexity of the immune system, this condition is not well understood, despite the significant research efforts devoted to it. To better understand ICI-induced autoimmune myocarditis, we suggest a new approach: mathematical modelling. Mathematical modelling of myocarditis can help determine which parts of the immune system are critical to the development and progression of the disease and therefore warrant further investigation. In this paper, we aim to provide the immunological background needed to develop a mathematical model of this disease and review relevant existing models of immunology that serve as the mathematical inspiration needed to start this effort.

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.

Background/AimsTo investigate immune-related ophthalmic side effects of systemic checkpoint inhibitors and compare side effect frequency and requirement for cessation of immunotherapy by checkpoint target.MethodsPatients taking immune checkpoint inhibitors at a single centre from January 1, 2010 to February 29, 2020 were retrospectively reviewed for clinical characteristics, treatments and concurrent systemic adverse effects.ResultsOf 996 patients, 28 (2.8%) experienced an ophthalmic side effect that came to the attention of an eye care provider. Mean age at presentation of the side effect was 63 years (median 64, range 25–88). The checkpoint inhibitor most often preceding side effects was pembrolizumab in 12 (43%). The most common side effect was dry eye in 16 (57%), followed by uveitis in 4 (14%) patients, and singular cases of ptosis and binocular diplopia, among others. Ocular surface adverse effects occurred more frequently with programmed death ligand-1 (PD-L1) targeting therapy. There were no significant differences in the frequency of orbit/ocular adnexa and uveitis or retinal side effects based on checkpoint targets. Follow-up was available in 13 (46%) patients, with mean duration of 20 months (median 16, range 2–52 months). Of these patients, the ophthalmic side effects were controlled without discontinuing therapy in 12 (92%). Checkpoint inhibitor cessation was required in one patient with panuveitis.ConclusionOphthalmic immune-related adverse events are rare but could be more common than previously estimated. PD-L1-directed checkpoint inhibitors may have a slight predilection for ocular surface adverse effects. Most ophthalmic events can be treated with targeted therapy without discontinuation of life-prolonging immunotherapy.

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.
