Multiple Drugs

Multiple drugs of a new class of cancer treatments called immune checkpoint inhibitors, which work by enabling the immune system to attack tumour cells, have been approved for a variety of indications in recent years. Immune checkpoints, such as cytotoxic T-lymphocyte antigen-4 and programmed death-1, are part of the normal immune system and regulate immune activation. Treatment with inhibitors of these checkpoints can significantly improve response rates, progression-free survival and overall survival of patients with cancer; it can also result in adverse reactions that present similarly to other conditions. These immune-mediated adverse reactions (IMARs) are most commonly gastrointestinal, respiratory, endocrine or dermatologic. Although patients’ presentations may appear similar to other types of cancer therapy, the underlying causes, and consequently their management, may differ. Prompt recognition is critical because, with appropriate management, most IMARs resolve and patients can continue receiving immune checkpoint inhibitor treatment. Rarely, these IMARs may be life-threatening and escape detection from the usual evaluations in the emergency environment. Given the unusual spectrum and mechanism of IMARs arising from immune checkpoint inhibitors, emergency departmentED staff require a clear understanding of the evaluation of IMARs to enable them to appropriately assess and treat these patients. Treatment of IMARs, most often with high-dose steroids, differs from chemotherapy-related adverse events and when possible should be coordinated with the treating oncologist. This review summarises the ED presentation and management of IMARs arising from immune checkpoint inhibitors and includes recommendations for tools and resources for ED healthcare professionals.

56 Background: Recent studies suggest that changes in the gut microbiome modulate response to cancer treatment, including immune checkpoint inhibitors (ICI). Broad-spectrum antibiotics (Abx) are known to cause significant dysbiosis. We hypothesize that recent Abx exposure worsens outcomes in patients (pts) with stage III/IV melanoma (MM) receiving ICI. Methods: We identified MM pts treated with ICI from our institutional database. All received their first ICI between 2004-2019. Antibiotic exposure was defined as receipt of Abx within 3 months prior to the first infusion of ICI. The primary outcome was overall survival (OS) and the secondary outcome was immune-mediated colitis requiring intravenous (IV) steroids. Stage III and IV pts were analyzed separately for the primary analysis. Results: Of 568 pts in our database, 20% received Abx within the 3 months prior to ICI. 36% of pts had stage III disease and 26% of pts were treated with either adjuvant or neoadjuvant ICI. 1.6% of pts died of causes other than MM. The Abx+ and Abx- groups were balanced in terms of stage, race, age, sex, BRAF status, LDH, prior systemic therapies, and class of ICI received. Only 4 pts were hospitalized due to the infection prompting the Abx, and no pts died due to the infection. In the Stage IV group, Abx+ pts had worse OS on MV analysis (HR 1.6, 95% CI 1.1-2.2). Stage III Abx+ also had worse OS (HR 2.8, 95% CI 1.3-5.9). In a sensitivity analysis excluding pts who received IV Abx or were admitted due to infection, survival was still worse for Abx+ pts (HR 1.7, 95% CI 1.2-2.4). In a Fine-Grey competing risk MV model, Abx+ had a higher rate of immune-mediated colitis requiring IV steroids (HR 2.1, 95% CI 1.02-4.5). Conclusions: In MM pts treated with ICI, receipt of Abx within 3 months prior to ICI initiation was associated with decreased OS and increased colitis. Future research should include prospective studies to better define the risk/benefit profile of antibiotics in close proximity to ICI. [Table: see text]

The Russian Federation

Recently immune checkpoint inhibitors amazingly changed the landscape of cancer therapy worldwide. The number of immune checkpoint molecules in clinical practice is constantly increasing. There are some monoclonal antibodies recently registered in the Russian Federation: anti-PD1 antibodies (nivolumab, pembrolizumab), anti-PD-L1 (atezolizumab, durvalumab), anti-CTLA-4 (ipilimumab). Immune-mediated endocrinopathies are some of the most common complications of immunotherapy. According to the results of clinical studies, the incidence of serious endocrine immuno-mediated adverse events with anti-PD1 monoclonal antibodies is low (3.5–8%). The use of anti-CTLA4 antibodies, combined regimens, and the use of immunotherapy after chemoradiotherapy significantly increase the incidence of serious adverse events to 30%. In clinical practice of N.N. Blokhin Cancer Research Center among 245 non-small cell lung cancer and hepatocellular carcinoma patients treated with immunotherapy, 22 (8,9%) developed an immune-mediated endocrinopathy. Most patients developed adverse events of 1–2 degrees, in two patients – 3 degrees, requiring discontinuation of treatment. The aim of this article was to provide useful information and recommendations regarding the management of common immuno-related endocrine adverse events (including hypothyroidism, hyperthyroidism, pituitary, adrenal insufficiency) for clinical oncologists.

Immune-mediated adverse events (imAEs) are complications of therapy with immune checkpoint inhibitors, which arise as a result of autoimmune inflammation. The article summarizes systemic (fatigue, fever), cutaneous (rash, itching), gastrointestinal (diarrhea, colitis, hepatitis, pancreatic dysfunction), endocrinological (hypothyroidism, hypophysitis, adrenal insufficiency, diabetes mellitus), pulmonary (pneumonitis, pleuritis), rheumatological (arthralgia), neurological (headache, sensory and motor disorders), renal (acute interstitial nephritis, lupus-like nephritis, granulomatous nephritis, diffuse interstitial nephritis and minimal change disease), hematological (anemia, cytopenia), cardiovascular (myocarditis) and ocular (conjunctivitis, episcleritis, ceratitis, blepharitis and uveitis) imAE. Pathogenetic mechanisms and treatment approaches (in accordance with toxicity grade and clinical recommendations) are discussed. Early symptom recognition, patient education and timely intervention are crucial for imAE correction.

Immune checkpoint inhibitors (ICIs) have gained prominence for the treatment of a variety of malignancies. However, they are associated with the development of immune-mediated adverse events (IMAEs). Appropriate management of IMAEs and subsequent rechallenging of patients with ICI therapy remains an important area of research. The primary endpoint of this study was to evaluate the efficacy of current prescribing practices and adherence to guideline recommendations for IMAE management. The incidence of symptom resolution, number of patients reinitiated with ICI therapy, and IMAE recurrence upon ICI therapy reinitiation were explored as secondary endpoints. A retrospective chart review within the Allegheny Health Network was conducted in cancer patients treated with ICI therapy who developed a documented ICI-associated IMAE and subsequently received corticosteroid therapy. IRB approval was obtained for this study. Descriptive statistics were used to analyze both primary and secondary endpoints. The study sample was made up of 81 patients. Overall, 50 out of 81 patient cases (62%) were found to be discordant with guideline recommendations; the primary factors identified were inappropriate starting corticosteroid dosing (64%), initiation of a corticosteroid taper prior to IMAE resolution to at least grade 1 severity, and condensed corticosteroid taper (74%). The main IMAEs identified were colitis (28%), pneumonitis (27%), and skin-related inflammation (12%). 76 out of the 81 patients (94%) achieved IMAE resolution; 41 patients (54%) were rechallenged with ICI therapy, of which 14 patients (34%) developed IMAE recurrence. Future studies may focus on evaluating different immunosuppression strategies to optimize IMAE management.

Programmed Death

Because of dramatic tumor regressions reported with the anti-programmed death-1 (PD-1) and anti-programmed death ligand-1 (PDL-1) antibodies inhibiting the PD-1 immune checkpoint, non-small cell lung cancer (NSCLC) is now recognized as an immune-modifiable disease. As responses were observed in smaller numbers in phase I trials, the immunologic profiles and unique toxicities of these agents have not been fully established in NSCLC. Moreover, PD-1 checkpoint inhibitors in development by different companies may demonstrate diverse spectrums of activity and toxicity. Although the cytotoxic T-lymphocyte antigen-4 (CTLA-4) checkpoint inhibitors in earlier phase studies appeared to have less impressive responses in NSCLC, their safety profile has been more broadly defined. The anti-CTLA-4 antibody, ipilimumab, has the best characterized immune-related toxicities (predominantly skin, gastrointestinal, hepatic, and endocrine) and management strategies in melanoma. Despite the lack of studies directly comparing these agents, toxicities from PD-1 inhibition seem milder than those of CTLA-4 inhibition, with distinct toxicities of pneumonitis infrequently observed with the BMS-936558 anti-PD-1 antibody, nivolumamb, and frequent mild infusion reactions reported with the BMS-936559 anti-PDL-1 antibody. As lungs are critical organs often already compromised in NSCLC patients, immune-mediated pneumonitis can cause worrisome morbidity and mortality. Even though immune checkpoint inhibitors are being rapidly developed in a multitude of trials, optimal immune-mediated toxicity management has not been determined, is evolving, and will be further explored. Early diagnosis and symptom management with corticosteroids form the basis of treatment. Assessment of new immune-response criteria and use of primary endpoints of overall survival (OS) will be important in the development of these immunotherapies in NSCLC.

Tumor Types

Immune checkpoint inhibitors have emerged as an effective treatment for several tumor types and their use in clinical practice is expected to further increase in the immediate future. Although these agents are well tolerated, they are associated with a peculiar spectrum of toxicity, which is immune mediated and may potentially affect every organ. However, immune-related adverse events are mostly reversible if promptly diagnosed and adequately treated. Therefore, it is crucial that medical oncologists know how to diagnose and treat immune-related adverse events. This review focuses on the pathogenesis, clinical manifestations and management of immune-related toxicity of anti-CTLA-4 and anti-PD-1 antibodies.
