BackgroundImmune-related adverse events (irAEs) are a serious side effect of immune checkpoint inhibitor (ICI) therapy for patients with advanced cancer. Currently, predisposing risk factors are undefined but understanding which patients are at increased risk for irAEs severe enough to require hospitalization would be beneficial to tailor treatment selection and monitoring.MethodsWe performed a retrospective review of patients with cancer treated with ICIs using unidentifiable claims data from an Aetna nationwide US health insurance database from January 3, 2011 to December 31, 2019, including patients with an identified primary cancer and at least one administration of an ICI. Regression analyses were performed. Main outcomes were incidence of and factors associated with irAE requiring hospitalization in ICI therapy.ResultsThere were 68.8 million patients identified in the national database, and 14 378 patients with cancer identified with at least 1 administration of ICI in the study period. Patients were followed over 19 117 patient years and 504 (3.5%) developed an irAE requiring hospitalization. The incidence of irAEs requiring hospitalization per patient ICI treatment year was 2.6%, rising from 0% (0/71) in 2011 to 3.7% (93/2486) in 2016. Combination immunotherapy (OR: 2.44, p<0.001) was associated with increased odds of developing irAEs requiring hospitalization, whereas older patients (OR 0.98 per additional year, p<0.001) and those with non-lung cancer were associated with decreased odds of irAEs requiring hospitalization (melanoma OR: 0.70, p=0.01, renal cell carcinoma OR: 0.71, p=0.03, other cancers OR: 0.50, p<0.001). Sex, region, zip-code-imputed income, and zip-code unemployment were not associated with incidence of irAE requiring hospitalization. Prednisone (72%) and methylprednisolone (25%) were the most common immunosuppressive treatments identified in irAE hospitalizations.ConclusionsWe found that 3.5% of patients initiating ICI therapy experienced irAEs requiring hospitalization and immunosuppression. The odds of irAEs requiring hospitalization were higher with younger age, treatment with combination ICI therapy (cytotoxic T lymphocyte-associated 4 and programmed cell death protein 1 (PD-1) or programmed death-ligand 1 (PD-L1)), and lower for other cancers compared with patients on PD-1 or PD-L1 inhibitors with lung cancer. This evidence from the first nationwide study of irAEs requiring hospitalization in the USA identified the real-world epidemiology, risk factors, and treatment patterns of these irAEs which may guide treatment and management decisions.

BackgroundImmune-related adverse events (irAEs) are serious side effects of immune checkpoint inhibitors (ICIs) for patients with advanced cancer. Understanding the epidemiology and risk factors for severe irAEs would be beneficial for patients and clinicians.MethodsWe performed a retrospective review of cancer patients treated with ICIs using un-identifiable claims data from a nationwide US health insurance plan from January 3rd, 2011 to December 31st, 2019. Patients with an identified primary cancer and at least one administration of an ICI were included in the study. We defined severe irAE as any inpatient hospitalization with new immunosuppression within 2 years after initiation of ICI. The main outcomes were incidence of severe irAE in ICI therapy and factors associated with severe irAE occurrence. Multivariable logistic regression, including Charlson comorbidity index, age, gender, primary cancer, region, and zip code average income and unemployment, was used to model risk factors for severe irAE (table 1).ResultsThere were 14,378 patients followed over 19,177 patient-years identified with a primary cancer and at least 1 administration of ICI. 504 (3.5%) patients developed a severe irAE. The incidence of severe irAEs per patient ICI treatment year was 2.6%, rising from 0% (0/71) in 2011 to 3.7% (93/2486) in 2016 (figure 1). Combination immunotherapy (OR: 2.44, p < 0.001) and younger age (OR: 0.77, p < 0.001) were associated with increased odds of developing severe irAEs, whereas patients with non-lung cancer were associated with decreased odds of irAEs (melanoma OR: 0.70, p = 0.01, renal cell carcinoma OR: 0.71, p = 0.03, other cancers OR: 0.50, p < 0.001; figure 1).

Abstract Background Immune checkpoint inhibitors (ICIs) can cause serious immune-related adverse events (irAEs). This study aimed to identify risk factors for all types of irAEs induced by ICIs in patients with non-small-cell lung cancer (NSCLC), by systematic review and meta-analyses. Methods A systematic search was performed in Pubmed, Embase and Web of Science by two independent reviewers. Studies were selected that included patients with NSCLC and evaluated characteristics of patients with and without irAEs induced by ICIs. Quality and risk of bias of the selected studies were assessed. Random effects meta-analyses were conducted to estimate pooled odds ratios (ORs) for risk factors of developing all type of irAEs, and separately for pneumonitis, interstitial lung disease and severe irAEs. With the objective of exploring sources of heterogeneity, stratified analyses were performed by quality and region. Results 25 studies met the inclusion criteria. In total, the data of 6696 patients were pooled. 33 different risk factors for irAEs were reported. irAEs of interest were reported for 1653 (25%) of the patients. Risk factors related to the development of irAEs were: C-reactive protein, neutrophil lymphocyte ratio (NLR), use of PD-1 inhibitor, high PD-L1 expression, an active or former smoking status, ground glass attenuation, and a better treatment response. Conclusion The identified risk factors for the development of these irAEs are mostly related to the alteration of the immune system, proinflammatory states and loss of immunological self-tolerance. Patients identified as having a higher risk for irAEs should be monitored more closely.

Effect Of Age

2638 Background: Immune checkpoint inhibitors (ICIs), such as programmed death(ligand)1 (PD-(L)1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors, have dramatic effects on treatment in patients with various malignancies. High tumor mutation burden (TMB) is predictive of clinical response to ICI in multiple cancer types. Although age-related immune dysfunction might induce difference on the efficacy of ICIs between younger and older patients, the potential effect of age on the efficacy of ICIs remains little known and controversial. Herein, we aimed to analysis the association between age and the efficacy of ICIs based on MSKCC cohort. Methods: We screened out 1661 patients having complete information with advanced cancer, whose tumors underwent next-generation sequencing (NGS) detection and who were treated with at least one dose of ICI in MSKCC cohort. All patients were divided into two groups according to age, the younger group (age ≤50-year old) and the older group (age > 50-year old). We further analyzed the differences in overall survival (OS) and TMB between the two groups. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated via Cox regression model for OS and P-values were calculated via the Wilcoxon sign test for TMB. We analyzed the effect of age on ICI in lung cancer using the same way. Results: In 1661 patients with cancer in our study, 312 (19%) younger and 1349 (81%) older patients were found. The pooled HRs for OS was 1.28 (95% CI: 1.09-1.52) in younger group compared with older group. In 1661 patients with cancer, there was 350 (21%) patients with lung cancer, including 30 (9%) younger and 320 (91%) older patients. The pooled HRs for OS was 1.45 (95% CI: 0.95-2.23) in younger group compared with older group in lung cancer. In addition, TMB in older group was higher than in younger group and significant difference of TMB was found via the Wilcoxon sign test (p = 2.6e-10) between the two groups, especially in lung cancer (p = 1e-4). Conclusions: Our study assessed the impact of age on the efficacy of ICIs using the threshold of 50 years old for the first time and we founded that patients in older group had higher TMB and longer OS than younger group.

BackgroundImmune checkpoint inhibitors (ICIs) have become the backbone of treatment for most driver-mutation negative, advanced non-small cell lung cancers. ICIs have been approved both as monotherapy and in combination with chemotherapy for front line management. While ICIs are generally regarded as well-tolerated, an unintended activation of the immune system can result in a variety of immune-related adverse events (irAEs), which can limit their use in severe cases. In patients with NSCLC treated with ICI monotherapy, the occurrence of an irAE and the development of multisystem irAEs have been associated with improved clinical outcomes, suggesting irAE occurrence could have prognostic implications.1–4 However, in patients treated with combination immunotherapy plus chemotherapy, the correlation between irAEs and survival has not been completely elucidated.MethodsWe conducted a retrospective chart review of 94 patients with advanced NSCLC treated with a combination of ICI plus chemotherapy between 2015 and 2021 to evaluate for a correlation between irAE occurrence and overall survival (OS). Patients were divided into two groups: those who experienced at least one irAE and those who did not experience an irAE. To account for immortal time bias, we conducted landmark analyses at 12 and 24 weeks. We additionally investigated the impact of multisystem irAEs on clinical outcomes and described the profile of irAEs observed at our institution.ResultsAmong the 94 evaluable patients identified in our population, 43.6% experienced at least one irAE. Of those patients who experienced an irAE, 26 (63.4%) experienced a single irAE, 9 (22.0%) experienced 2 irAEs, and 6 (14.6%) experienced 3 or more irAEs. The most commonly observed irAEs were dermatitis followed by pneumonitis and colitis. In our cohort, patients with at least one irAE had significantly longer median OS (16.8 mos vs 9.8 mos) compared to those who did not experience an irAE (HR 0.51, 95% CI 0.43–0.76, p=0.011) (figure 1). Landmark survival analyses at 12 and 24 weeks continued to support significant differences in median OS based on presence or absence of an irAE (HR 0.49, 95% CI 0.24–0.46, and HR 0.45, 95% CI 0.21–0.60 respectively). Among patients with at least one irAE, the subset of patients who experienced multiple irAEs had further improved median OS compared to those with a single irAE.ConclusionsIn patients with advanced NSCLC treated with combination ICI plus chemotherapy, the occurrence of an irAE is associated with improved overall survival.ReferencesTeraoka S, Fujimoto D, Morimoto T, et al.

e21218 Background: Early recognition of immune-related adverse events (irAEs) of immune checkpoint inhibitors(ICI) is important. Circulating proteome reflects host response to diseases and is being explored as a marker for response to immunotherapy. We previously have reported that a serum-based proteomics test, Primary Immune Response (PIR) demonstrated a trend that PIR-sensitive patients are more likely to tolerate ICI treatment longer without developing irAEs in non-small cell lung cancer (NSCLC) patients. The VeriStrat test is another serum-based proteomic assay, which was reported to be predictive of survival outcomes for all treatment regimens and lines of therapy including ICI in NSCLC. We explored the associations between the VeriStrat test and developing irAEs in NSCLC patients treated with ICI. Methods: Data of 70 consented NSCLC patients treated with any regimens and lines of therapy including ICI were collected. Samples were grouped into either VeriStrat ‘Good’(VS-G) or VeriStrat ‘Poor’(VS-P). We analyzed the durations from the immunotherapy initiation to each episode of irAE and each irAE above grade 2 using log-rank test. IrAEs were graded according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Results: Among the 70 patients, 18 patients (25%) experienced one or more irAEs. There was no significant difference in ‘Time to first irAE’ between VS-G and VS-P (p = 0.72, HR = 0.82, 95% CI = 0.29-2.32). Among 48 VS-G patients, 12(25%) had one or more irAE and 5(10%)had irAE graded over 2. Among 22 VS-P patients, 6(27%) had one or more irAE and 2(9%) had irAE graded over 2. There was no significant difference between VS-G and VS-P groups in the development of irAE and irAE graded over 2. Conclusions: There was no statistically significant association between the VeriStrat test and the development of irAEs. Further studies are warranted to investigate proper serum based proteomic assay to predict the development of irAE.

Introduction: With the widespread use of immune checkpoint inhibitors (ICIs), we are facing challenges in the management of immune-related adverse events (irAEs). We aimed to characterize the spectrum of toxicity, management, and outcomes for irAEs. Methods: Patients who were treated with at least one ICI in clinical trials, expanded access programs, or routine clinical practice were included. Clinical and laboratory parameters were collected retrospectively to determine the incidence of irAEs, methods of management, and treatment outcomes. Results: A total of 255 patients were screened retrospectively. Of these, 71 (27.8%) patients developed irAEs. More than 2 different types of irAEs were detected in 16 (6.2%) out of 255 patients. A total of 3177 doses were given to 255 patients. In 93 (2.9%) of the 3177 doses, 1 episode of irAEs was experienced. A total of 22 out of 93 (23.7%) episodes were reported as grade 1, 49 (52.7%) as grade 2, 19 (20.4%) as grade 3, and 3 (3.2%) as grade 4. The most frequently seen irAEs were pneumonitis, hepatitis, and hypothyroidism. With regard to treatment, 39 out of 93 episodes (42%) of any grade irAEs occurred after anti–programmed cell death-1 therapy, 47 (50.5%) occurred following administration of anti–programmed death-ligand 1, and 7 (7.5%) occurred after combination treatments. Conclusion: With the increased use of immunotherapeutic agents, increased awareness and early recognition are required for effective management of irAEs. Our experience as a single institution might be of use for health care providers in oncology.

e14140 Background: Immune checkpoint inhibitors (ICIs) are known to cause immune-related adverse events. Patients with autoimmune diseases (AID) were excluded from most ICI clinical trials due to the potentially high risk of adverse effects. Data on the safety of ICIs in patients with a diagnosis of AID is therefore limited. Methods: A retrospective cohort study was conducted using a de-identified large oncology health care and pharmacy claims database with data from March 2010 until April 2017. Patients analyzed had a diagnosis of either melanoma or lung cancer and were treated with either of the anti-PD-1 inhibitors nivolumab or pembrolizumab. We assessed whether patients with AID compared with no AID were more likely to require medical interventions within 180 days of ICI therapy. We determined the percentage of patients receiving oral prednisone, IV methylprednisolone, or were hospitalized, which may represent responses to ICI toxicity. Results: 16.7% (16/96) of patients with either melanoma or lung cancer and AID received oral prednisone treatment within 180 days of ICI treatment, while 8.3% (131/1573) of patients without AID received oral prednisone during the same period. 8.4% (16/190) of patients with AID received IV methylprednisolone compared to 3.6% (79/2190) of patients without AID. Among melanoma patients, 24.1% (13/54) of patients with AID were hospitalized following ICI treatment, compared to 5.8% (28/480) of patients without ICI. Among lung cancer patients, 38.2% (52/136) of patients with AID were hospitalized compared to 31.6% (541/1711) of patients without AID. All comparisons are significant at p < 0.05 except hospitalizations in lung cancer patients. Conclusions: Patients with AID were more likely to receive interventions after ICI treatment that may represent responses to immune-related adverse events, suggesting that patients with AID are at increased risk for toxicity when being treated with ICIs.

3140 Background: The identification of risk factors for immune-related adverse events (irAEs) is an important area of research. Among irAEs, pneumonitis carries one of the highest morbidities. There is a lack of strong predictors for pneumonitis in patients (pts) treated with ICI. We sought to identify predictors for the development of pneumonitis, and whether the use of inhaled corticosteroids (ICS) at time of ICI could be protective. Methods: Pts with advanced cancer treated with ICI from 2011 and 2018 were included in this retrospective study. Pneumonitis attribution to ICI was determined by treating physician at time of diagnosis. Time to pneumonitis was defined as days from the start of ICI to pneumonitis diagnosis. Pts who never had pneumonitis were censored at the time of last follow up or death. Predictors of pneumonitis were assessed by univariate Cox proportional hazard models at a significance threshold of alpha = 0.05. Results: A total of 837 pts were identified, and 30 (3.6%) pts developed any grade pneumonitis (12 grade 2, 14 grade 3, 1 grade 4, 3 grade 5) after receiving ICI (Table). Pts with age ≥65 years (y) had increased risk of developing pneumonitis over pts with age < 65y (HR 2.1, 95 CI: 1.02-4.4, p=0.041). 82 (9.7%) of the total cohort were on inhaled corticosteroid (ICS) at time of ICI, and 9 (11%) developed pneumonitis. Rather than being protective, pts on ICS had higher risk of pneumonitis (HR 4.2, 95 CI: 1.9-9.2, p=0.001). Pts with lung cancer had an increased risk for pneumonitis compared to pts with other cancers (HR 3.2, 95 CI: 1.5-6.4, p =0.003). Other risk factors included performance status, smoking history, line of therapy, or prior treatment including radiation were not statistically significant. Conclusions: Rather than a protective effect of ICS, our analysis found a higher risk of pneumonitis in pts treated with ICS. We confirmed an increased risk of pneumonitis for lung cancer pts compared to pts with other cancers, and higher risk of pneumonitis in pts age >65y. We hypothesize that the increased inflammatory status in chronic lung inflammation may predispose pts to pneumonitis that was not ameliorated by ICS. Future study is needed in prospective cohorts to further clarify the underlying inflammatory mechanism. [Table: see text]

Purpose: To estimate the frequency of first-time ocular events in patients treated with immune checkpoint inhibitors (ICI). Methods: Patients with cancer in 2011–2018 in Denmark were included and followed. The outcomes were first-time ophthalmologist consultation and ocular inflammation. One-year absolute risks of outcomes and hazard ratios were estimated. Results: 112,289 patients with cancer were included, and 2195 were treated with ICI. One year after the first ICI treatment, 6% of the patients with cancer, 5% and 8% of the lung cancer (LC) and malignant cutaneous melanoma (MM) patients, respectively, had a first-time ophthalmologist consultation. The risk of ocular inflammation was 1% (95% confidence interval (CI) 0.4–1.2). Among patients with MM, ICI was associated with ocular inflammation in women (HR 12.6 (95% CI 5.83–27.31) and men (4.87 (95% CI 1.79–13.29)). Comparing patients with and without ICI treatment, the risk of first-time ophthalmologist consultation was increased in patients with LC (HR 1.74 (95% CI 1.29–2.34) and MM (HR 3.21 (95% CI 2.31–4.44). Conclusions: The one-year risks of first-time ophthalmologist consultation and ocular inflammation were 6% and 1%, respectively, in patients treated with ICI. In patients with LC and MM, the risk was increased in patients with ICI compared with patients without ICI.
