Abstract Immune checkpoint inhibitors such as anti-CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), anti-PD-1 (programmed cell death protein 1), and PD-L1 (programmed cell death protein-ligand 1) are emerging drugs that have radically changed treatment and prognosis of different types of tumors. However, despite their considerable benefits, immune checkpoint inhibitors are associated with numerous side effects involving several organs. Gastrointestinal toxicities represent some of these most common adverse events. While clinical presentation usually ranges from mild diarrhea to life-threatening colitis, typical endoscopic and histologic findings of immune-mediated colitis often resemble those of inflammatory bowel diseases. However, less common patterns are lymphocytic colitis and, rarely, collagenous colitis. Physician and pathologists must be aware of the wide spectrum of clinical and histological findings that may be encountered in immune-related gastro-intestinal toxicities. We report a rare and atypical case of collagenous colitis occurred in a woman affected by stage IV lung adenocarcinoma, on atezolizumab therapy.

Abstract Context Immune checkpoint inhibitors, including anti–programmed cell death protein 1 (PD-1), anti–programmed cell death protein ligand 1 (PD-L1), and anti–cytotoxic T-lymphocyte antigen 4 (anti-CTLA4) monoclonal antibodies, have been widely used in cancer treatment. They are known to cause immune-related adverse events (irAEs), which resemble autoimmune diseases. Anterior pituitary hypophysitis with secondary hypopituitarism is a frequently reported irAE, especially in patients receiving anti–CTLA4 treatment. In contrast, posterior pituitary involvement, such as central diabetes insipidus (DI), is relatively rare and is unreported in patients undergoing PD-1/PD-L1 blockade. Case Description We describe a case of a 73-year-old man with Merkel cell carcinoma who received the anti–PD-L1 monoclonal antibody avelumab and achieved partial response. The patient developed nocturia, polydipsia, and polyuria 3 months after starting avelumab. Further laboratory testing revealed central DI. Avelumab was held and he received desmopressin for the management of central DI. Within 6 weeks after discontinuation of avelumab, the patient’s symptoms resolved and he was eventually taken off desmopressin. The patient remained off avelumab and there were no signs or symptoms of DI 2 months after the discontinuation of desmopressin. Conclusion To our knowledge, this is the first report of central DI associated with anti–PD-L1 immunotherapy. The patient’s endocrinopathy was successfully managed by holding treatment with the immune checkpoint inhibitor. This case highlights the importance of early screening and appropriate management of hormonal irAEs in subjects undergoing treatment with immune checkpoint inhibitors to minimize morbidity and mortality.

Introduction: Immune checkpoint inhibitors revolutionized anti-neoplastic treatment. Recently, the European Medicines Agency and the United States Food and Drug Administration approved inhibitors of various immune checkpoints, namely the cytotoxic T-lymphocyte-associated protein 4, programmed cell death protein 1 and its ligand. Despite the added benefits in the treatment of several neoplasms, immune checkpoint blockade may also be associated with multiple immune-related adverse events.Material and Methods: A literature review in PubMed database on the cutaneous toxicity of immune checkpoint inhibitors was performed until April 30, 2019.Results and Discussion: A total of 380 articles were initially screened, of which 75 are the basis of this bibliographic review. The immune checkpoint inhibitors monoclonal antibodies produce their beneficial effects by activating the patient’s immune system. This activation also results in adverse events that can affect any organ, whereas cutaneous toxicity is the most frequent and precocious. The adverse events of the programmed cell death protein 1 and its ligand and of the cytotoxic T-lymphocyte-associated protein 4 are similar (class effect), despite the apparent higher skin toxicity of inhibitors of the cytotoxic T-lymphocyte-associated protein 4 (or its use in combination with inhibitors of programmed cell death protein 1 and its ligand). The most common cutaneous toxicities are maculopapular exanthema and pruritus, but other more specific adverse effects (e.g. lichenoid or psoriasiform reaction, vitiligo, sarcoidosis, among others) or located in the oral mucosa and/or adnexa are underreported.Conclusion: Given the high rate of cutaneous toxicity associated with new immune checkpoint inhibitors and their impact on quality of life, their early recognition and appropriate approach are crucial in the treatment of cancer patients. Observation by a dermatologist should be provided in patients with certain toxicities.

Bladder cancer (BC) is one of the most common cancers in the world. From an early age, it was observed that chronic inflammation is associated with conditions favorable to the development of tumors, as well as the tumor microenvironment. Moreover, regulating tumor progression also interferes with the therapy’s response. The interaction between the tumor and the immune system led to the development of new immune therapies, the immune checkpoint inhibitors. Immunotherapy has shown a better safety profile, survival, and tolerance compared to standard chemotherapy. This therapy offers an effective alternative to patients who are ineligible for cisplatin and patients with advanced disease progression after platinum-based therapy. The first immunotherapy approved for BC was intravesical instillation with Bacillus Calmette–Guérin, for tumors at early stages. Later, immunotherapy focused on immune checkpoint inhibitors, namely, anti-programmed cell death protein 1 (PD1), anti-programmed cell death protein ligand 1(PD-L1), and anti-antigen 4 associated with cytotoxic T cells (CTLA-4). Currently, five immune checkpoint inhibitors for advanced BC are approved by the Food and Drug Administration (FDA): Atezolizumab, Durvalumab, Avelumab, Pembrolizumab, and Nivolumab. This review addresses the correlation between inflammation, tumor microenvironment, and cancer; various studies regarding immune checkpoint inhibitors, either in monotherapy or in combination therapy, are also addressed.

The development of immune checkpoint inhibitors (ICIs) targeting cytotoxic T lymphocyte antigen 4 (CTLA-4), programmed cell death protein 1 (PD-1), or programmed cell death protein ligand 1 (PD-L1) has revolutionized the treatment strategy in various types of cancers. In addition, recent studies have revealed that tumor microsatellite instability (MSI) status and tumor mutation burden (TMB) contribute significantly to the therapeutic response to anti-PD-1 monoclonal antibody (mAb), which led to an accelerated approval to pembrolizumab for the treatment of MSI-high or mismatch-repair-deficient solid tumors after conventional chemotherapies in 2017 and for the treatment of TMB-high solid tumors in 2020 by the United States Food and Drug Administration (FDA). In the field of gastrointestinal cancers, many clinical trials evaluating the safety and efficacy of various regimens such as ICI monotherapy, the combination of anti-CTLA-4 mAb and anti-PD-1/PD-L1 mAb, and combination of ICI and conventional chemotherapy or tyrosine kinase inhibitor have been reported or are in progress. This review summarizes MSI status and TMB in gastrointestinal, hepatobiliary, and pancreatic cancers, and provides the results of most relevant clinical trials evaluating ICIs. We also discuss the development of biomarkers required for improving the selection of patients with a high probability of benefiting from treatment with ICIs, and potential therapeutic strategies that could help to enhance anticancer responses of ICIs.

BackgroundICI revolutionized modern Oncology landscape and being utilized in metastatic to adjuvant and neo-adjuvant settings. As Oncologists, we are treating cancer patients with ICI every day, yet there is still a lot that is unknown about these drugs. We don’t have clear understanding of the efficacy and toxicity when sequencing one ICI for another. We conducted a retrospective review of real world data at Lahey Hospital and Medical Center to understand further and to pave path for prospective studies to understand this issue further to improve patient care.MethodsWe retrospectively reviewed Oncology patient charts who received ICI between January1, 2014 to December 18, 2018. Total 483 patients received ICI during this time frame and 22 of these patients received a second ICI either as monotherapy or in combination with other ICI or chemotherapy.ResultsA total of 22 patients received subsequent ICI after the initial ICI as showed in table 1. 15 of the 22 (68%) patients were transitioned from one ICI to another monotherapy. 11 of these patients were transitioned secondary to disease progression (73%), three had immune related adverse events and one was switched per standard of care. One patient had ICI re-challenge. Three patients had a transition from ICI monotherapy to combination ICI therapy. One patient went onto chemo-immunotherapy and 2 patients transitioned from combination ICI to chemo-immunotherapy.Abstract 284 Table 1Real world data of sequencing immune checkpoint inhibitors (ICI) after initial ICIConclusionsICI therapy is evolving and patients are being treated with multiple lines of ICI. In current practices, ICI is frequently being transitioned from cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death 1 (PD-1) or its ligand, programmed cell death ligand 1 (PD-L1) classes or combined with chemotherapy or targeted therapy. It would be prudent to explore the effects of sequencing these medications either as a monotherapy or in combination with other therapies to better serve our patients and to prevent financial toxicity.

Activated T Cells

Immune checkpoint inhibitors target suppressor receptors, including cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4), programmed cell death protein 1 (PD-1), and programmed cell death ligand 1 (PD-L1). The activated T cells are not antigen specific; therefore, the blockade of the immune checkpoint may result in the development of autoimmune adverse events. The most common immune-related adverse events (irAEs) are rash, colitis, and endocrinopathies. However, irAEs that affect the hematologic system are rare and can affect red blood cells (e.g., autoimmune hemolytic anemia), white blood cells, and platelets (e.g., immune thrombocytopenia). Usually one cell line is affected; however, in some cases, multiple cell lines can be affected. Other changes in the hematologic system can also be affected (e.g., cryoglobulinemia, cytokine release syndrome). Due to the rarity and lack of recognition of these AEs, the timing, spectrum of events, and clinical presentation are poorly understood. Management of hematologic irAEs usually involves the use of steroids; however, other agents (e.g., IVIG, cyclosporine, rituximab) or procedures (e.g., plasma exchange, transfusions) can also be used.

Incidence And Mortality

: Hepatocellular Carcinoma (HCC) is one of the most common malignancies, the incidence and mortality of which are increasing worldwide. Cancer immunotherapy has revolutionized cancer treatment in recent years. In particular, Immune Checkpoint Inhibitors (ICIs) as new therapeutic tools have demonstrated encouraging antitumor activity and manageable tolerability in HCC. Immunologic checkpoint blockade with antibodies targeting Programmed cell Death-1 (PD-1), Programmed cell Death Ligand-1 (PD-L1), and Cytotoxic T Lymphocyte-Associated protein-4 (CTLA-4) strengthens tumor immunity by restoring exhausted T cells. Although the efficacy of combination treatment strategies using ICIs combined with other ICIs, molecular targeted agents, systemic therapy, or locoregional therapy has been well documented in numerous preclinical and clinical studies on several types of cancers, most HCC patients do not benefit from ICI treatment. This review highlights recent developments and potential opportunities related to ICIs and their combination in the management of HCC. The present article also includes recent patent review coverage on this topic.

Immune checkpoint inhibitors, including antibodies targeting programmed cell death protein-1 (PD-1) and its receptor programmed cell death ligand-1 (PD-L1), represent promising therapeutic strategies for advanced human malignancies. However, a subgroup of patients experiences various autoimmune toxicities, termed immune-related adverse events (irAEs), that occur as a result of on-target and off-tumor autoimmune responses. Although irAEs are generally confirmed to be less severe than toxicities caused by conventional chemotherapy and targeted therapy, uncommon irAEs, such as immune thrombocytopenia, may occur with a very low incidence and sometimes be severe or fatal. This review focuses on the epidemiology, clinical presentation, and prognosis of immune thrombocytopenia occurring in advanced cancer patients induced by immune checkpoint inhibitors, especially in those with PD-1 or PD-L1 inhibitor treatment. We also first present one patient with non-small cell lung cancer who received the PD-L1 inhibitor durvalumab and developed severe thrombocytopenia.

Immune checkpoint inhibitors (ICIs), including antibodies targeting programmed cell death protein-1 (PD-1) and programmed cell death ligand-1 (PD-L1), are being extensively used on advanced human malignancies therapy. The treatment with ICIs have acquired durable tumor inhibition and changed the treatment landscape in lung cancer. Immune-related adverse events including pneumonitis and thyroiditis have been well described, but less frequent events, such as ICIs-induced thrombocytopenia, are now emerging and may sometimes be severe or fatal. Since early detection and prompt intervention are crucial to prevent fatal consequences, it is of outmost importance that medical staff is aware of these potential toxicities and learn to recognize and treat them adequately. This review focuses on the epidemiology, clinical presentation, mechanisms, and clinical management of ICIs-induced thrombocytopenia in patients with lung cancer. We also present a patient with advanced lung adenocarcinoma who received the PD-L1 inhibitor atezolizumab and eventually developed severe thrombocytopenia. The case indirectly suggests that cytokine changes might contribute to immune dysregulation in ICIs-induced thrombocytopenia.
