The use of immune checkpoint inhibitors is associated with a spectrum of immune-related adverse events related to the mechanism of action which is quite different from that of cytotoxic chemotherapy. Adverse effects can affect multiple organs of the body and are most common in the skin, gastrointestinal tract, lungs, and endocrine tissues, including the thyroid, adrenal gland, pituitary gland, as well as musculoskeletal, renal, nervous, hematologic, cardiovascular, and ocular systems. Any changes should be considered as being related to treatment with immune checkpoint inhibitors. Adverse events are very infrequent, but may be very serious and, even lethal, such as neurological disorders and myocarditis. When compared with standard chemotherapeutic agents, programmed death 1/programmed deathligand 1inhibitors are associated with a lower incidence of bone marrow suppression, anorexia, nausea, vomiting, and diarrhea. Immune checkpoint inhibitor therapy can usually continue in the presence of mild immune-related adverse events with close monitoring. However, moderate to severe immune-related adverse events may be associated with a severe decline in organ function and quality of life, and may result in fatal outcomes. Hence, these toxicities require early detection and proper management. The management of immune-related adverse events usually involves corticosteroid therapy or the use of immunomodulators. The use of immune checkpoint inhibitors in patients with preexisting autoimmune disease or a history of prior organ transplant should include careful consideration and a robust discussion of potential risks and benefits.

e14580 Background: The use of immune-checkpoint inhibitors (ICIs) for solid malignancies is rapidly rising, and many new agents and treatment combinations are in development. However, ICIs have a unique side-effect profile of immune-related adverse events (irAEs) compared with chemotherapeutic agents or targeted therapies. The aim of this work was to describe the irAEs in diverse types of malignant tumors using real-world data. Methods: This is a retrospective and descriptive study of patients with diverse types of advanced malignancies treated with immunotherapy at Centro Oncológico Integral of the Hospital Ángeles in Puebla, México; during the period 2016-2020. Data about the primary neoplasm, ICIs, irAEs, organ system affected, grade and treatment was collected. Clinical and laboratory parameters were obtained by reviewing medical records. Results: A total of 117 patients were included, median age of 65 years, of which 63.2% were male and 36.8% were female. The most frequent neoplasms treated with ICIs were: lung (27.4%), kidney (16.2%), melanoma (12.8%), hepatocellular (9.4%), breast (8.5%), non-melanoma skin cancer (6.0%), mesothelioma (4.3%) and other tumors (15.3%). 39.3% of the patients had no metastases, 41.9% had metastases to at least 1 or 2 sites, and 18.8% to 3 or more sites. The types of ICIs were: nivolumab (35.0%), pembrolizumab (28.2%), atezolizumab (23.9%), ipilimumab + nivolumab (12.0%) and durvalumab (0.9%). The most frequent irAEs were: gastrointestinal (61.5%), neurologic (46.2%), pulmonary (38.5%), metabolic (32.5%) and hematologic (29.1%). 39.3% of the irAEs were reported as grade 1, 31.6% as grade 2, 14.5% as grade 3 and 2.6% as grade 4. Conclusions: Our work shows the incidence of irAEs in a poorly studied population and provides new data that complement that reported by other works, however, further prospective studies are necessary.[Table: see text]

Introduction Immune agents including anti-programmed death receptor-1 and anti-cytotoxic T-lymphocyte antigen-4 have been associated with numerous immune-related complications. Pembrolizumab, a programmed death-1 inhibitor, has been associated with a number of immune-related adverse events such as pneumonitis, colitis, hepatitis, hypophysitis, hyperthyroidism, hypothyroidism, nephritis, and type 1 diabetes. Case report We present a rare case of an elderly male on pembrolizumab who suffered from four autoimmune toxicities including type 1 diabetes, pneumonitis, hypothyroidism, and polymyalgia rheumatica likely catalyzed by age-related immune activation. Management and outcome: Immunotherapy was indefinitely stopped, and patient was started on steroids for the immune-related adverse events with complete resolution of polymyalgia rheumatica. Thyroid dysfunction resolved once he started thyroid replacement therapy. His diabetes is well controlled with insulin and is followed by endocrinology. He continues on prednisone for immune-mediated pneumonitis with a good response with regular monitoring via computed tomography scans and pulmonary consultation. Discussion Few cases wherein multiple toxicities are seen within one patient are reported. Aging appears to be a risk factor for immune-related adverse events. Aging is associated with an increased incidence of autoimmunity as programmed death-1 ligand expression represents an important mechanism that tissues use to protect from self-reactive effector T cells. Programmed death-1 blockade breaks this protective mechanism and enhances autoimmune diseases. Therefore, close monitoring and extreme vigilance is warranted while using immune checkpoint inhibitors including pembrolizumab as multiple toxicities can occur within a short span of infusion, especially in elderly individuals. Prompt discontinuation and the use of a multidisciplinary team are prudent to prevent further morbidity and mortality.

Introduction Nivolumab, a programmed death-1(PD-1) inhibitor antibody, have demonstrated anti-tumor activity for multiple malignancies. Such immune checkpoint inhibitors induce novel and distinctive adverse effects, which are collectively named immune-related adverse events. Immune-related adverse events can theoretically occur at any part of the body, including the haemopoietic system. Most immune-related adverse events developed within 10 weeks of receiving immunotherapy. Thus far, there is no report of immune thrombocytopenia as an immune-related adverse event developed after discontinuation of immunotherapy. Case report We describe a 62-year-old male with metastatic non-small cell lung cancer developed immune thrombocytopenia nearly two months after discontinuation of nivolumab. When thrombocytopenia was detected, the patient was undergoing radiotherapy of supraclavicular lymph nodes. After complex diagnosis-by-exclusion process, nivolumab-induced immune thrombocytopenia was diagnosed. Management and outcome Intravenous immunoglobulins 20 g daily for 5 days, intravenous methylprednisolone 40 mg daily for 14 days followed by oral prednisone, intermittent platelet transfusion and oral thrombopoietin receptor (eltrombopag 25 mg daily) were administered. After 30 days, his platelet count had achieved a level of adequate hemostasis and continued to improvement during the tapering period. Discussion Most immune-related developed 6 months of immunotherapy. Clinicians need to be aware of a clinical diagnostic complex, developing months to years after discontinuation of immunotherapy, which recently is termed delayed immune-related events. This case is the first report of immune checkpoint inhibitors-induced thrombocytopenia that developed nearly 2 months after discontinuation of treatment with nivolumab for metastatic NSCLC. In future clinical practice, patients who have received immune checkpoint inhibitors develop new or unexplained symptom, irrespective of interval post-immunotherapy, immune-related adverse events should be considered.

Abstract INTRODUCTION In several cancers treated with immune checkpoint inhibitors (ICIs), a remarkable association between the occurrence of immune-related adverse events (irAEs) and superior oncological outcomes has been reported. This effect has hitherto not been reported in the brain. This study aimed to investigate the relation between irAEs and outcomes in brain metastases (BM) patients treated with both local treatment to the brain (LT; i.e. surgery and/or radiation) and ICIs. METHODS This study is a retrospective cohort analysis of patients treated for non-small cell lung cancer (NSCLC) BMs in a tertiary institution in Boston, MA. Outcomes of interest were overall survival (OS) and intracranial progression-free survival (IC-PFS), measured from the time of LT. Sensitivity analyses were performed to account for immortal time bias (i.e., patients who live longer receive more cycles of ICIs and thus have more opportunity to develop an irAE). RESULTS A total of 184 patients were included; 62 (33.7%) were treated with neurosurgical resection and 122 (66.3%) with upfront brain radiation. irAEs occurred in 62 patients (33.7%). After adjusting for lung-Graded Prognostic Assessment, type of LT, type of ICI, newly diagnosed vs. recurrent BM, BM size and number, targetable mutations, and smoking status, irAEs were strongly associated with better OS (HR 0.33, 95% CI 0.19 – 0.58, p < 0.0001) and IC-PFS (HR 0.41; 95% CI 0.26 – 0.65; p = 0.0001). Landmark analysis including only patients who received more than 3 cycles of ICI (n = 133) demonstrated similar results for OS and IC-PFS, as did sensitivity analysis adjusting for the number of cycles administered (HR range 0.36 – 0.51, all p-values < 0.02). CONCLUSIONS After adjusting for known prognostic factors, irAEs strongly predict superior outcomes after LT in NSCLC BM patients. Sensitivity analysis suggests that this is unlikely due to immortal time bias.

Abstract Background Immune checkpoint inhibitors (ICI) have become standard treatment in different tumor entities. However, safe treatment with ICI targeting the PD-1/PD-L1 axis requires early detection of immune-related adverse events (irAE). There exist different questionnaires of drug manufacturers for the detection of irAE that have not been validated so far. Methods The prospective non-interventional ST-ICI trial studied treatment with PD-1/PD-L1 ICI alone or combined with radiotherapy. In the current analysis, the detection rate of self-reported irAE with a patient questionnaire containing 41 different questions was compared to clinician-reported irAE. Results Between April 2017 and August 2019, a total of 104 patients were prospectively enrolled. NSCLC (44%) and HNSCC (42%) were the most frequent tumor entities. A total of 784 questionnaires were collected. A total of 29 irAE were reported by clinicians. The most frequent irAE was hypothyroidism (9%), followed by skin reactions (5%), hepatitis (4%), diarrhea (3%), and pneumonitis (3%). Questions that became significantly more often positive at time points of clinician-reported irAE were “weight change”, “difficulty to grip things”, “bloody or mucous stool” and “insomnia”. Self-reported organ-specific questions detected at least 50% of clinician-reported irAE of gastrointestinal, lung, endocrine, and skin irAE. It was not possible to detect hepatic irAE with the questionnaire. Conclusion Questionnaires can help to detect gastrointestinal, lung, endocrine, or skin irAE, but not hepatic irAE. Questions on “weight change” and “insomnia” may help to increase the detection rate of irAE, besides organ-specific questions. These results are a valuable contribution to the future development of a specific and practicable questionnaire for early self-reported detection of irAE during ICI therapy in cancer patients.
