Correlation between immune-related adverse events and prognosis in patients with gastric cancer treated with nivolumab

Abstract Background Recent studies have shown that immune-related adverse events (irAEs) caused by immune checkpoint inhibitors were associated with clinical benefit in patients with melanoma or lung cancer. In advanced gastric cancer (AGC) patients, there have been few reports about the correlation between irAEs and efficacy of immune checkpoint inhibitors. In this study, we retrospectively investigated the correlation between irAEs and efficacy in AGC patients treated with nivolumab. Methods The subjects of this study were AGC patients received nivolumab monotherapy between January 2015 and August 2018. IrAEs were defined as those AEs having a potential immunological basis that required close follow-up, or immunosuppressive therapy and/or endocrine therapy. We divided the patients who received nivolumab into two groups based on occurrence of irAEs; those with irAEs (irAE group) or those without (non-irAE group). We assessed the efficacy in both groups. Results Of the 65 AGC patients that received nivolumab monotherapy, 14 developed irAEs. The median time to onset of irAEs was 30.5 days (range 3–407 days). Median follow-up period for survivors was 32 months (95% CI, 10.8 to 34.5). The median progression-free survival was 7.5 months (95% CI, 3.6 to 11.5) in the irAE group and 1.4 months (95% CI, 1.2 to 1.6) in the non-irAE group (HR = 0.11, p < 0.001). The median overall survival was 16.8 months (95% CI, 4.4 to not reached) in the irAE group and 3.2 months (95% CI, 2.2 to 4.1) in the non-irAE group (HR = 0.17, p < 0.001). Multivariate analysis demonstrated that number of metastatic sites ≥2 (HR = 2.15; 95% CI, 1.02 to 4.54), high ALP level (HR = 2.50; 95% CI, 1.27 to 4.54), and absence of irAEs (HR = 9.54, 95% CI, 3.34 to 27.30 for yes vs. no) were associated with a poor prognosis. The most frequent irAEs was diarrhea/colitis (n = 5). Grade 3 adverse events were observed in 6 patients; hyperglycemia (n = 2), diarrhea/colitis (n = 1), adrenal insufficiency (n = 1), aspartate aminotransferase increased (n = 1), peripheral motor neuropathy (n = 1). There were no grade 4 or 5 adverse events related to nivolumab. Conclusions Development of irAEs was associated with clinical benefit for AGC patients receiving nivolumab monotherapy.

In advanced gastric cancer (AGC) patients, there have been few reports about the correlation between irAEs and efficacy of immune checkpoint inhibitors. Therefore, in this study, we retrospectively investigated the correlation between irAEs and efficacy in AGC patients treated with nivolumab. Methods: The subjects of this study were AGC patients that had received nivolumab monotherapy between January 2015 and August 2018.

One of the 14 patients experienced the irAE after discontinuation of nivolumab due to progression of disease. There were no grade 4 or 5 adverse events related to nivolumab. Conclusions: Development of irAEs was associated with clinical benefit for AGC patients receiving nivolumab monotherapy.

BackgroundImmune-related adverse events (irAEs) caused by immune checkpoint inhibitors (ICIs) were associated with clinical benefit in cancer patients of melanoma, a lung cancer. In the present study, we investigated the correlation between irAE and ICI efficacy in hepatocellular carcinoma (HCC) patients.MethodsWe divided the HCC patients who received the anti-PD-1 antibody into two groups as irAE group and non-irAE group according to the National Cancer Institute Common Terminology Criteria for Adverse Events ver. 4.03. The treatment efficacy of ICIs was evaluated with objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS).ResultOf the 65 HCC patients who received the anti-PD-1 antibody (monotherapy or combined with targeted medicine), median PFS in the irAE group was superior to that in the non-irAE group (302 days vs. 148 days, p = 0.004). Median OS in the irAE group was also better than that in the non-irAE group (374 days vs. 279 days, p = 0.038). Although the statistical difference for DCR in the irAE group and non-irAE group was not reached, the DCR of the irAE displayed a trend better than that of the non-irAE group (41.20% vs. 20.80%, p = 0.118). Multivariate analysis also demonstrated that the non-irAE group (HR = 6.410, 95% CI: 1.404 to 29.275) was associated independently with the poor prognosis.ConclusionsDevelopment of irAEs was associated with clinical benefit for HCC patients who were treated with immune checkpoint inhibitors; irAE, particularly low-grade irAE, was a predictable marker for better ICI treatment efficiency in HCC patients.

Background:Description and initial management of rheumatic immune-related adverse-events (irAEs) from cancer immunotherapies have been reported by several groups but to date, few studies have evaluated the long-term outcomes and management of rheumatic irAEs (1).Objectives:To describe the long-term management and assess the one-year outcomes of patients who experienced rheumatic immune-related adverse events (irAEs) due to immune checkpoint inhibitors (ICI).Methods:This was a single-centre prospective observational study including patients referred for musculoskeletal symptoms while treated with ICI. After baseline rheumatological evaluation defining the clinical entity presented, follow-up visits were organised according to the type and severity of irAE. At one year, persistence of irAE, ongoing treatment, as well as cancer outcomes were assessed.Results:63 patients were included between September 2015 and June 2018. 24 patients (38%) presented with non-inflammatory musculoskeletal conditions managed with short-term symptomatic treatment and did not require specific follow-up. 39 patients (62%) experienced inflammatory manifestations, mimicking either rheumatoid arthritis (RA, n=19), polymyalgia rheumatica (PMR, n=16), psoriatic arthritis (PsA, n=3) and one flare of a preexisting axial spondyloarthritis. Overall, 32 patients (82%) received systemic glucocorticoids, with a median rheumatic dosage of 15mg/day (range: 5-60mg/day). None of the patients had to permanently discontinue ICI therapy for rheumatic irAE. 20 patients (67%) were still receiving glucocorticoids at one year, with a median dosage of 5mg/day (range: 2-20mg/day). Glucocorticoids were more frequently discontinued for patients with RA-like condition (44%) than PMR-like condition (23%), but no other predictive factor of glucocorticoids withdrawal could be identified. At one year, overall survival and progression-free survival were comparable between patients who were still receiving glucocorticoids for rheumatic irAE and patients who have discontinued. Eight patients required csDMARDs.Conclusion:At one year, a majority of patients required long-term low-dose glucocorticoids for chronic rheumatic irAE, which seems not altering oncological control.References:[1]Braaten TJ, Brahmer JR, Forde PM, et al.

Significant Difference

Introduction: The use of immune checkpoint inhibitors (ICIs) is associated with an increase in cardiovascular events. The mechanism is likely related to immune activation and inflammation. Patients with pre-existing autoimmune disease have a baseline increased risk for cardiovascular disease and have been traditionally excluded from clinical trials of ICIs. There is limited data on the cardiovascular and non-cardiovascular safety of ICIs in these patients. Methods: This was a retrospective study of 2845 patients treated with an ICI at the Massachusetts General Hospital. This cohort was screened by individual chart review for patients with a diagnosis of an autoimmune disease prior to ICI therapy. These autoimmune patients were compared to controls at a 1:2 ratio. Baseline characteristics and risk of cardiovascular and non-cardiovascular immune related adverse events (iRAEs) were compared. Cardiovascular events were a composite of myocardial infarction (MI), percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), stroke, transient ischemic attack (TIA), deep venous thrombosis (DVT), pulmonary embolism (PE), or myocarditis. Results: 93 patients had a diagnosis of an autoimmune disease prior to ICI. These patients were more likely to be older and to have a history of coronary artery disease, heart failure, chronic kidney disease, hypertension and diabetes mellitus. There were 12 events over a median follow-up period of 300 days. There was no significant difference in composite of cardiovascular events in follow-up (13 vs. 9.1%, autoimmune vs. none, P =0.41). The individual cardiovascular event rates were as follows: MI (4.3 vs. 0.5%, P =0.04), PCI (0 vs. 0.5%, P =1), CABG (0. vs. 0.5%, P =1), stroke (0 vs. 0%), TIA (0 vs. 0.5%, P =1), DVT (5.4 vs. 2.2%, P =0.17), PE (1.1 vs. 4.8%, P =0.17), and myocarditis (2.2 vs. 1.1%, P =0.60). There was an increased rate of pneumonitis (14 vs. 4%, P <0.001) and skin toxicity (16 vs. 0%, P <0.001). Conclusions: Patients with pre-existing autoimmune disease treated with an ICI had a higher baseline cardiovascular risk but did not have a significant increase in cardiovascular events in an unadjusted analysis. These patients did, however, have an increased rate of pneumonitis and skin toxicity after ICI.

BackgroundThe efficacy of immune checkpoint inhibitors (ICI) in metastatic melanoma is well established. However, there are limited data regarding their efficacy in in-transit melanoma (ITM). This study assessed the efficacy of ICI in patients with ITM.MethodsA retrospective review of patients with ITM commenced on an ICI between March 2013 and February 2018 at three tertiary centers in Australia. Patients were excluded if they had previous or synchronous distant metastases. Overall response rate (ORR), progression-free survival (PFS) and overall survival (OS) were based on a composite of radiological and clinical assessments.ResultsFifty-four patients were included: 27 (50%) female; median age 75 (range 26–94); 12 (22%) stage IIIB, 40 (74%) stage IIIC and 2 (4%) stage IIID; 10 (19%) BRAF mutant. Forty (74%) received single-agent anti-PD-1 (pembrolizumab or nivolumab), 8 (15%) single agent anti-CTLA-4 (ipilimumab), 5 (9%) combination anti-PD-1/anti-CTLA-4 (ipilimumab and nivolumab or pembrolizumab) and 1 (2%) combination anti-PD-L1 (atezolizumab) and MEK inhibitor (cobimetinib). The median follow-up was 15 months (2–46).ORR to ICI was 54%: 14 (26%) complete responses; 15 (28%) partial responses; 9 (17%) stable disease; 16 (30%) progressive disease. Thirteen (46%) responders had only one ITM lesion. ORR was 58% for single-agent anti-PD-1, 38% for single-agent anti-CTLA4 and 40% for anti-PD-1/anti-CTLA-4. The median PFS was 11.7 months (6.6-not reached). 1-year and 2-year PFS were 48% and 39%, respectively,. Fourteen progressed locoregionally and 11 progressed distantly. The median OS was not reached. 1-year and 2-year OS were 85% and 63%, respectively. No clinicopathological features were associated with ORR.Conclusions and relevanceICI produce objective responses in ITM and should be considered in patients with unresectable ITM or disease recurrence.

Objective: To investigate the role of CTLA-4, PD-1 (programmed death-1), and PD-L1 (programmed death-ligand 1) single nucleotide polymorphisms (SNPs) in predicting clinical outcome of patients with advanced non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). Methods: A total of 166 consecutive patients were included. We correlated SNPs with clinical benefit, progression-free survival, time to treatment failure, and overall survival and evaluated the incidence of SNPs in nonresponder and long clinical benefit groups. Results: Considering the entire cohort, no correlation was found between SNPs and clinical outcome; however, PD-L1 rs4143815 SNP and the long clinical benefit group showed a statistically significant association ( p = 0.02). The nonresponder cohort displayed distinctive PD-L1 haplotype ( p = 0.05). Conclusion: PD-L1 SNPs seem to be marginally involved in predicting clinical outcome of NSCLC treated with ICI, but further investigations are required.

Objective: Immune checkpoint inhibitors (ICI) can cause endocrine adverse events. However, endocrine AEs could be related to better treatment outcomes. Our aim was to investigate whether this holds true in a real-world setting of metastatic melanoma patients. Design: A retrospective single-institution study. Methods: We included 140 consecutive metastatic melanoma patients treated with ICI between January 2012 and May 2019. We assessed endocrine toxicity and best possible treatment outcomes from electronic patient records, including laboratory parameters, and radiological images. Results: Of the treated patients, 21 patients (15%) were treated with ipilimumab, 46 (33%) with nivolumab, 67 (48%) with pembrolizumab, and six (4%) with combination therapy (ipilimumab + nivolumab). Endocrine AEs appeared in 29% (41/140) patients. Three patients had two different endocrine AEs. Thyroid disorders were the most common: 26% (36/140), followed by hypophysitis: 4% (5/140). Three subjects (2%, 3/140) were diagnosed with autoimmune diabetes. Three patients had to terminate treatment due to endocrine toxicity. Radiological manifestations of endocrine AEs were found in 16 patients (39%, 16/41). Endocrine toxicity was associated with significantly better treatment outcomes. Median progression-free survival (8.1 months, range 5.1 – 11.1 months vs. 2.7 months, range 2.4 – 3.0 months, P < 0.001), and median overall survival (47.5 months, range 15.5 – 79.5 months vs. 23.7 months, range 15.3 – 32.1 months, P = 0.035) were longer for patients experiencing endocrine AEs. Conclusions: The higher number of endocrine AEs suggest regular laboratory monitoring aids in AE detection. Endocrine AEs in metastatic melanoma may correlate with better treatment outcomes.

The Impact

Introduction Immune checkpoint inhibitors (ICIs) have become the standard of care in many cancer types. As the number of patients receiving ICIs for various cancers continues to expand, patients and practitioners should be aware of potentially severe immune-related adverse events (irAEs). Despite reports of the incidence of grade 3/4 toxicities, the proportion of patients whose symptoms were clinically severe enough to warrant hospitalization for adverse event management is unknown. Methods This single center, retrospective, observational study was designed to determine the impact of irAEs on patients and the hospital. Patients who started ICIs from May 2016 through May 2019 for melanoma or lung cancer were included. The primary outcome was incidence of hospitalization for irAE. Secondary outcomes included median length of hospitalization, time to onset of irAE, rates of hospitalization for irAE per each checkpoint inhibitor regimen, organ system affected, progression free survival, and overall survival. Results Of 384 patients with melanoma or lung cancer, 27 (7%) were hospitalized at our institution for an irAE. The most common irAE leading to hospitalization was colitis for patients with melanoma and pneumonitis for patients with lung cancer. The median length of stay across all hospitalizations was 10 days. Twenty-five patients required the use of corticosteroids while hospitalized, while eight of these patients required second line irAE treatment. For the total patient population, 34.7% experienced a grade 1/2 irAE and 13.1% experienced a grade 3/4 irAE. Conclusion Our cohort of patients experienced similar rates irAEs as reported in clinical trials and published reports.

61 Background: Immune checkpoint inhibitors (ICPis) have improved survival in melanoma patients, however their use is associated with 5-60% patients experiencing severe immune related adverse events (irAEs). Severe irAEs may affect survival benefit imparted by ICPis. Objective: We aimed to analyze disease outcomes with resumption of immunotherapy as compared to non-resumption of immunotherapy in patients with severe irAEs (Grade 3/4 in CTCAE v5.0). Methods: Patients with melanoma being treated with ICPis who developed severe irAEs were discussed in an institutional irAE tumor board (TB). We analyzed all patients discussed in TB from September 2017 to September 2019 for cancer outcome of withholding versus resuming immunotherapy in the face of severe irAEs. Results: Out of 26 total patients with melanoma discussed in TB, 23 had severe irAE. Colitis was the most common irAE 9/23 (39.1%) followed by 2/23 (8.7%) of pneumonitis and hepatitis each. ICPi was resumed in 8 patients (resume group) (median age 53, range 42-67) and withheld in 15 patients (non-resume group) (median age 57, range 42-91). In the resume group all 8 patients (100%) are alive, of which 2/8 (25%) had disease progression (median follow up 106.5wk, range 35wk-131wk); whereas, in the non-resume group 9/15 (60%) progressed, of which 6/15 (40%) died (median follow up 91wk, range 3wk-197wk). Conclusions: Our data suggest that the ability to resume ICPi after an episode of severe irAE is associated with better prognosis in terms of disease progression and survival. Immunotherapy being the mainstay of the management in metastatic melanoma, inability to resume therapy is associated with worse prognosis. Timely management of irAEs should be prioritized in order to resume treatment.

Wide Range

Recently, the overall survival (OS) and progression-free survival (PFS) of patients with advanced cancer has been significantly improved due to the application of immune checkpoint inhibitors (ICIs). Low response rate and high occurrence of immune-related adverse events (irAEs) make urgently need for ideal predictive biomarkers to identity efficient population and guide treatment strategies. Cytokines are small soluble proteins with a wide range of biological activity that are secreted by activated immune cells or tumor cells and act as a bridge between innate immunity, infection, inflammation and cancer. Cytokines can be detected in peripheral blood and suitable for dynamic detection. During the era of ICIs, many studies investigated the role of cytokines in prediction of the efficiency and toxicity of ICIs. Herein, we review the relevant studies on TNF-α, IFN-γ, IL-6, IL-8, TGF-β and other cytokines as biomarkers for predicting ICI-related reactions and adverse events, and explore the immunomodulatory mechanisms. Finally, the most important purpose of this review is to help identify predictors of ICI to screen patients who are most likely to benefit from immunotherapy.
