Abstract BACKGROUNDAlong with antitumor effects, Immune Checkpoint Inhibitors (ICPI) have shown great potential in treating chronic infections such as HIV, Hepatitis B and malaria, in ex-vivo studies. However, several case reports and case series have suggested an increased infection risk in cancer patients. The purpose of our study was to assess the risk of infections in cancer patients receiving ICPI. We also attempted to evaluate the role of a multidisciplinary approach (Oncology and Infectious disease specialists) and the cost associated with treatment. METHODS:Records on all cancer patients over age ≥18 years old who had received at least one dose of ICPI between 2015 to 2018 at a major community teaching hospital in the central Massachusetts region were reviewed. Several risk factors associated with infection were identified. A two-tailed, unpaired t-test was used to analyze the association between risk factors and infection. We calculated the cumulative length of stay (LOS) and cost per admission with a multidisciplinary vs. non-multidisciplinary approach. The calculated total average cost per admission was compared to a matched population (without an oncologic diagnosis) admitted with infections similar to that in our study, to compare the economic burden. RESULTSRetrospective chart review of 169 cancer patients receiving ICPI showed sixty-two episodes of infection in thirty-seven (21.8%) patients and a mortality rate of 3.5% due to associated complications. Risk factors like COPD, prior chemotherapy and steroid use were significantly associated (P<0.05) with infections. Further sub-group analysis showed increase in cumulative LOS from 5.9 to 8.1 days but approximately similar average cost per admission ($52,047 vs. $54,510) with non-multidisciplinary vs. multidisciplinary approach. The calculated total cost per admission during an episode of infection in this cohort of patients was $35,484; three-fold higher when matched to similar infections in a general non-oncologic population ($11,527). CONCLUSIONSA significant incidence of infections and associated health care resource utilization continues to prevail in cancer patients despite the utility of ICPI. A multidisciplinary approach to manage the infections and associated complications in cancer patients receiving ICPI increased the cumulative LOS but not the average cost per admission.

Cancer Associated Thrombosis

SummaryPurpose Anticancer agents are known to increase cancer-associated thrombosis (CAT) onset. CAT onset rate is reported to be 1.92% in cisplatin-based therapy, 6.1% in paclitaxel plus ramucirumab combination therapy, and 11.9% in bevacizumab monotherapy. Because immune checkpoint inhibitors (ICIs) cause a sudden increase in T cell number, an association between administration of these drugs and increase in CAT incidence is likely. However, the extent to which ICI administration affects CAT incidence remains unclear. Further, risk factors for CAT incidence have not yet been identified. The present study investigated CAT incidence and associated risk factors in patients receiving ICI. Methods Patients administered nivolumab or pembrolizumab at Fujita Health University Hospital from April 2017 to March 2018 were enrolled. We collected retrospective data regarding age, sex, cancer type, BMI, medical history, laboratory data at treatment initiation, medications, and computed tomography (CT) interpretations from electronic medical records. Results We identified 122 eligible participants from 135 patients receiving nivolumab or pembrolizumab. Ten patients (8.2%) developed CAT. A history of venous thromboembolism (VTE) or arterial thromboembolism (ATE) was a risk factor for CAT incidence (odds ratio: 6.36, P = 0.039). A history of heart disease may be a risk factor for CAT incidence (odds ratio 6.56, P = 0.052). Significantly higher usage of antiplatelet and anticoagulant therapy was noted in patients who developed CAT (60%) than in those who did not (13.4%, p < 0.01). Conclusion High (8.2%) CAT incidence during ICI administration suggested that ICI is not associated with a lower blood clot risk than other anticancer agents investigated in previous studies. For patients with VTE, ATE, or heart disease history, it is crucial to consider the possibility of CAT even with antiplatelet therapy.

Real World Data

e15100 Background: Immune checkpoint inhibitors (ICIs) can cause unique, high-grade immune-related adverse events. Although rare, ICI related myocarditis has the highest fatality rate (~50%). Cardiovascular monitoring is not routinely performed in patients on ICI treatment, thus risk factors remain unknown. Characterizing rare but fatal cardiac toxicities requires integration of real-world data. Methods: U.S claims data (IBM MarketScan) of over 30 million commercially insured individuals was leveraged to identify 2,687,301 cancer patients between 2011-2018. Patients ≥18 years of age treated with ICIs (targeting CTLA4 (ipilimumab) and/or the PD1 (nivolumab, pembrolizumab)/PDL1 (atezolizumab, avelumab, durvalumab) alone or in combination with ICI and/or chemotherapy were identified and followed until disenrollment. Myocarditis, comorbidities, and treatment details were identified using diagnosis and billing codes. Analyses included descriptive statistics and Cox proportional hazards regression. Results: 16,541 ICI treated cancer patients were included (median age 60; 58% male). Myocarditis was identified in 252 (1.5%) patients, majority (90%) ≥50 years old (median 63) with 12,040 person-years of follow up. 62% received anti-PD1 monotherapy, 12% anti-CTLA4, and 15% received combination treatment with other ICIs and/or chemotherapy. Most common cancer types were lung (48%), melanoma (25%), and renal cancer (14%). Cumulative incidence of myocarditis at 1 year was 2.06%; 95% CI (1.78-2.37), median onset of 80.5 days, 42% occurring within 60 days of treatment. By univariate analyses, age, cancer type, diabetes (DM), hypertension (HTN), kidney, liver disease, atrial fibrillation (AF) were related to myocarditis. Risk was lower in patients who received anti-CTLA4 monotherapy (HR: 0.490; 95% CI: 0.26-0.92; p = 0.0251). On multivariable regression analyses only age, cancer type (renal, lung cancer), comorbidities DM and liver disease were significantly associated with myocarditis (Table). Conclusions: This is the largest real-world longitudinal study for ICI associated myocarditis showing higher than reported incidence and identifiable risk factors. [Table: see text]

Underlying Mechanisms

In recent years, immune checkpoint inhibitors (ICIs) have become the standard treatment option for tumors. With the widespread application of ICIs, immune-related adverse events (irAEs) have gradually attracted the attention of researchers. Owing to the characteristics of ICIs, irAEs can affect each organ of the human body. Thromboembolism is uncommon in cancer patients receiving ICIs, but it may affect their survival. Most thromboembolic events do not cause serious effects after early prediction and treatment, but life-threatening toxic reactions are also observed. This condition should not be ignored because of vague and atypical symptoms, which make early diagnosis more challenging. This article focuses on the high-risk factors, underlying mechanisms, incidence, and prognosis of thromboembolism in patients using ICIs and briefly describes the intervention and treatment measures. This information would allow patients to effectively manage the side effects of thromboembolism during Immune checkpoint inhibitors treatment, ensuring the efficacy of ICIs and reducing mortality.

Methods: Records on all cancer patients over age ≥18 years old who had received at least one dose of ICPI from 2015 to 2018 at two major community teaching hospitals in the Central Massachusetts region were reviewed. Several risk factors associated with infection were identified. Two-tailed unpaired t-test was used to analyze the association between risk factors and infection. We calculated the average length of stay (LOS) and cost per admission with a multidisciplinary vs. non-multidisciplinary approach. The calculated total average cost per admission was compared with a random set of non-oncologic population admitted with similar infections noted in our study to estimate the economic burden. Results: Thirty-seven (21.8%) patients developed sixty-two episodes of infection. Microbiological confirmation was available in 13 episodes. Risk factors like COPD (P = 0.01), prior chemotherapy (P = 0.03), and steroid use (P = 0.003) were significantly associated with infections. An infection-associated mortality rate was noted to be 2.3%. With the involvement of multidisciplinary team, the average LOS increased from 5.9 to 8.1 days. Yet, the average cost per admission approximately remained the same (52,047$ vs. 54,510$). Upon comparison with a non-oncologic patient, the average cost per admission for an infection in cancer patients receiving ICPI increased from 11,527$ to 35,484$. Conclusions: Surprisingly, a significant incidence of infections and associated health care resource utilization continue to prevail in cancer patients despite the utility of ICPI. Although the economic burden due to the infections in this set of patients is remarkably high when compared to the general population, the multidisciplinary approach did not increase the hospital costs.

e21503 Background: The use of immune checkpoint inhibitors (ICIs) drastically transformed the treatment of lung cancer. However, a variety of response rates have been observed in patients due to intrinsic or acquired resistances. STK11 mutated patients represent a subgroup of lung cancer patients with diminished outcomes when given ICIs, with some of these patients developing hyperprogressive disease (HPD). Methods: In this study, a retrospective cohort of 384 lung cancer patients previously treated with ICIs was identified from the City of Hope Thoracic Registry (THOR) with a cutoff date of November 11, 2018. Next-generational sequencing (NGS) was performed on 246 patients. 24 of these patients were harboring an alteration in STK11. Data was collected on these patients until December 31, 2019. HPD was exclusively defined by time-to-treatment failure (TTF) < 2 months (TTF is defined as the time from the start of treatment with ICI to ICI discontinuation for any reason, including progression, patient preference, toxicity, or death). Overall survival (OS) and progression free survival (PFS) was started from the initiation of ICI therapy. OS and PFS was calculated between 2 groups (HPD vs non-HPD) using the Mantel-Cox Log-rank test. Results: Almost half (11/13; 45.8%) of the patients with STK11 developed HPD. There was a significant difference between HPD and non-HPD patients in median OS (2 vs 23 months; p = 0.0013) and median PFS (1 v 9 months; p < 0.0001). The median age was 66 (range, 41-90) years old with the majority of patients female (14/24; 58.3%). Most of the patients are deceased (16/24; 66.7%). 91.7% of STK11 patients histologically were adenocarcinoma and 91.7% were smokers with a median pack year history of 40 (range, 4-90). All of the patients had metastatic disease presenting with stage IV disease (21/24; 87.5%). ICI therapies used were pembrolizumab (11/24; 45.8%), Atezolizumab (8/24; 33.3%), nivolumab (4/24; 16.7%), and durvalumab (1/24; 4.2%). PD-L1 expression varied: negative (8/24; 33.3%), 1%- < 50% (7/24; 29.2%), ≥50% (4/24; 16.7%), and not reported (5/24; 20.8%). The most commonly occurring co-mutations were found in TP53 (14/24; 58.3%), KRAS (12/24; 50.0%), SMARCA4 (9/24; 37.5%), PRKDC (8/24; 33.3%) and LRP1B (8/24; 33.3%). Three patients had a pathological co-mutation that is targetable (1 ALK rearrangement, 1 EGFR exon 19 deletion, and 1 RET fusion). Conclusions: STK11 patients who developed HPD had worse OS and PFS compared to STK11 patients without HPD. These results are preliminary and additional analysis is needed to compare differences between various cohorts.

Immune checkpoint inhibitors (ICPIs) agents can cause endocrine immune-related adverse events (irAEs).Aim. Determine the incidence, time of onset and risk factors of endocrine irAEs in cancer patients treated with anti-PD1 and anti-CTLA-4 immunotherapy.Materials and methods. This is a retrospective single-center study that included 61 patients aged 28 to 81 years with diagnosed cancer of the lungs, ovaries, esophagus, stomach, bladder, kidney, and pleural mesothelioma. 44 (72%) patients received anti-PDL1/anti-PD1 monotherapy and 17 (28%) received a combination of anti-PD1 + anti-CTLA-4. Calculated: odds ratio (OR) and 95% confidence interval (CI).Results. The incidence of endocrine irAEs was 23% (14 patients): thyroiditis (13%), hypophysitis (8%), adrenal insufficiency and diabetes mellitus (2–3%). IrAEs occurred in 9 (20%) patients with monotherapy and in 5 (35%) patients when using a combination of drugs (p=0.318). The average time of onset of irAEs did not differ depending on the applied regimen and amounted to 6 [4–18] weeks. Symptomatic irAEs developed in 2 (13%) patients. Discontinuation of ICPI therapy due to irAE was not required in any case. Risk factors: age younger than 61 years old – OR 4.4 (95% CI 1.198–16.242), female OR 2.4 (95% CI 0.67–8.591), presence of stage IV disease – OR 2.4 (95% CI 0.689–8.362), combination therapy OR 1.855 (95% CI 0.548–6.277), previous endocrine pathology – OR 0.813 (95% CI 0.152–4.356).Conclusions. The incidence of endocrine irAEs when using ICPI is 23%. Thyroiditis and hypophysitis develop more often. The odds are higher in patients younger than 61 years. In most cases, irAEs are not symptomatic and do not require discontinuation of ICPI therapy.

Thoracic Malignancies

Lung cancer patients undergoing systemic treatment with immune checkpoint inhibitors (ICIs) can lead to severe immune-related adverse events (irAEs) that may warrant immediate hospitalization. Patients with thoracic malignancies hospitalized at City of Hope while undergoing treatment with ICIs were identified. Pathology and available next-generation sequencing (NGS) data, including the programmed death-ligand 1 (PD-L1) status and clinical information, including hospitalizations, invasive procedures, and the occurrence of irAEs, were collected. Unpaired T-tests, Chi-square/Fisher’s exact test, and logistic regression were used to analyze our cohort. The overall survival (OS) was calculated and compared using univariate and multivariate COX models. Ninety patients with stage IV lung cancer were admitted after ICI treatment. Of those patients, 28 (31.1%) had documented irAEs. Genomic analyses showed an enrichment of LRP1B mutations (n = 5/6 vs. n = 7/26, 83.3% vs. 26.9%; odds ratio (OR) (95% confidence interval (CI): 13.5 (1.7–166.1); p < 0.05) and MLL3 mutations (n = 4/6, 66.7% vs. n = 5/26, 19.2%; OR (95% CI): 8.4 (1.3–49.3), p < 0.05) in patients with irAE occurrences. Patients with somatic genomic alterations (GAs) in MET (median OS of 2.7 vs. 7.2 months; HR (95% CI): 3.1 (0.57–17.1); p < 0.05) or FANCA (median OS of 3.0 vs. 12.4 months; HR (95% CI): 3.1 (0.70–13.8); p < 0.05) demonstrated a significantly shorter OS. Patients with irAEs showed a trend toward improved OS (median OS 16.4 vs. 6.8 months, p = 0.19) compared to hospitalized patients without documented irAEs. Lung cancer patients who required treatment discontinuance or interruption due to irAEs (n = 19) had significantly longer OS (median OS 18.5 vs. 6.2 months; HR (95% CI): 0.47 (0.28–0.79); p < 0.05). Our results showed a significant survival benefit in lung cancer patients hospitalized due to irAEs that necessitated a treatment interruption. Patients with positive somatic GAs in MET and FANCA were associated with significantly worse OS compared to patients with negative GAs.
