Project description:Over the past decade, immune checkpoint inhibitors (ICI) have dramatically improved the prognosis of many cancer patients, but many immune-related adverse cardiovascular events (ACEs) have been observed. We aimed to investigate the occurrence of ACEs in the real world after receiving ICI and provide clinical reference for how to evaluate it. The study retrospectively included 204 patients who received ICI from October 2019 to November 2020 and 205 patients who only received traditional chemotherapy. The mean duration of follow-up for ICI group was 4.88 months, and the control group was 4.79 months. Patients in the control group did not develop myocarditis, only 2 cases of new-onset pericardial effusion occurred. In contrast, among ICI group, there were 3 cases of ICI-associated myocarditis, accounting for 1.47% (3/204), 6 cases of pericardial effusion. The incidence of new-onset ECG abnormalities in the ICI group was significantly higher than that of the control group (38/180 VS 16/178, HR 2.71, 95% CI: 1.449-5.067, P=0.001). In the ICI group, after receiving ICI treatment, cardiac biomarkers including average cardiac troponin T and N terminal pro B type natriuretic peptide increased significantly, peak in about 1 month, and then gradually decreasing. After the third or fourth month, the cardiac biomarkers gradually increased again. In conclusion, ICI may lead to various ACEs, and its incidence is higher than that of patients who only receive traditional chemotherapy. The changing trend of cardiac biomarkers reflects that ICI may cause acute and chronic myocardial damage. Regularly performing ECG, echocardiogram and cardiac biomarker examinations are helpful for early detection of ACEs caused by ICI and providing timely treatment.

Project description:BackgroundTreatment strategies are limited for patients with chemotherapy refractory microsatellite stable (MSS) colorectal cancer. We aim to evaluate the efficacy and safety of immune checkpoint inhibitors (ICIs) combined with regorafenib in this population in routine clinical practice.MethodsWe retrospectively analyzed patients with advanced or metastatic colorectal cancer who received at least one dose of ICIs combined with regorafenib in 14 Chinese medical centers. The primary outcome was objective response rate (ORR). This study was registered at ClinicalTrials.gov on February 2020 (NCT04771715).ResultsEighty-four patients received ICIs combined with regorafenib from January 2019 to January 2021. Most patients (91%) received two or more systemic treatment lines before the study treatment. Seventy-six patients (90%) had confirmed MSS status. At a median follow-up of 5.5 months, four patients achieved partial response (5%) and 37 patients achieved stable disease (45%) as the best response. The median progression-free survival (PFS) was 3.1 months, and the median overall survival was 17.3 months. Eleven patients (13%) remained progression-free for more than 6 months. Baseline liver metastasis (HR 1.98, 95%CI 1.07-3.69, P = 0.03) and neutrophil-lymphocyte ratio (NLR) of ≥ 1.5 (HR 2.83, 95%CI 1.00-7.98, P = 0.05) were associated with shorter PFS in multivariate analysis. Grade 3 or higher treatment-related adverse events (TRAEs) occurred in 16 patients (19%).ConclusionThe combination of ICIs with regorafenib can be a valuable treatment option for a proportion of patients with chemotherapy refractory MSS colorectal cancer. Patients with no liver metastasis and a low NLR at baseline may derive most benefit from this strategy.

Project description:BackgroundImmune checkpoint inhibitors (ICIs) have substantially improved clinical outcomes in multiple cancer types and are increasingly being used in early disease settings and in combinations of different immunotherapies. However, ICIs can also cause severe or fatal immune-related adverse-events (irAEs). We aimed to identify and characterise cardiovascular irAEs that are significantly associated with ICIs.MethodsIn this observational, retrospective, pharmacovigilance study, we used VigiBase, WHO's global database of individual case safety reports, to compare cardiovascular adverse event reporting in patients who received ICIs (ICI subgroup) with this reporting in the full database. This study included all cardiovascular irAEs classified by group queries according to the Medical Dictionary for Regulatory Activities, between inception on Nov 14, 1967, and Jan 2, 2018. We evaluated the association between ICIs and cardiovascular adverse events using the reporting odds ratio (ROR) and the information component (IC). IC is an indicator value for disproportionate Bayesian reporting that compares observed and expected values to find associations between drugs and adverse events. IC025 is the lower end of the IC 95% credibility interval, and an IC025 value of more than zero is deemed significant. This study is registered with ClinicalTrials.gov, number NCT03387540.FindingsWe identified 31 321 adverse events reported in patients who received ICIs and 16 343 451 adverse events reported in patients treated with any drugs (full database) in VigiBase. Compared with the full database, ICI treatment was associated with higher reporting of myocarditis (5515 reports for the full database vs 122 for ICIs, ROR 11·21 [95% CI 9·36-13·43]; IC025 3·20), pericardial diseases (12 800 vs 95, 3·80 [3·08-4·62]; IC025 1·63), and vasculitis (33 289 vs 82, 1·56 [1·25-1·94]; IC025 0·03), including temporal arteritis (696 vs 18, 12·99 [8·12-20·77]; IC025 2·59) and polymyalgia rheumatica (1709 vs 16, 5·13 [3·13-8·40]; IC025 1·33). Pericardial diseases were reported more often in patients with lung cancer (49 [56%] of 87 patients), whereas myocarditis (42 [41%] of 103 patients) and vasculitis (42 [60%] of 70 patients) were more commonly reported in patients with melanoma (χ2 test for overall subgroup comparison, p<0·0001). Vision was impaired in five (28%) of 18 patients with temporal arteritis. Cardiovascular irAEs were severe in the majority of cases (>80%), with death occurring in 61 (50%) of 122 myocarditis cases, 20 (21%) of 95 pericardial disease cases, and five (6%) of 82 vasculitis cases (χ2 test for overall comparison between pericardial diseases, myocarditis, and vasculitis, p<0·0001).InterpretationTreatment with ICIs can lead to severe and disabling inflammatory cardiovascular irAEs soon after commencement of therapy. In addition to life-threatening myocarditis, these toxicities include pericardial diseases and temporal arteritis with a risk of blindness. These events should be considered in patient care and in combination clinical trial designs (ie, combinations of different immunotherapies as well as immunotherapies and chemotherapy).FundingThe Cancer Institut Thématique Multi-Organisme of the French National Alliance for Life and Health Sciences (AVIESAN) Plan Cancer 2014-2019; US National Cancer Institute, National Institutes of Health; the James C.

Project description:BackgroundReal-world evidence on immune-related adverse events (irAEs) are relatively insufficient. Herein patterns and outcomes of irAEs after administration of anti-programmed cell death 1 (PD-1) and its legend 1 (PD-L1) antibodies were investigated.MethodsPatients treated with anti-PD-1/PD-L1 drugs from January 2018 to September 2021 at Huadong Hospital, Fudan University were included. Common Terminology Criteria for Adverse Events (CTCAE) was used for irAEs evaluation. The primary endpoints were the clinical description of irAEs.ResultsTwo hundred and forty-one solid tumor patients were included, with lung cancer as the most common tumor type (56%). 187 (77.6%) patients presented any kind of irAEs. The median time to any irAE onset was 28 (95% CI 24-32) days. Skin toxicities are the most common irAEs (46.1%) and the irAEs (36.5%) occurred earliest after immune-checkpoint inhibitors. The most frequently occurred all-grade irAEs were rash (23.7%), myelosuppression (20.7%), and hepatic injury (19.5%). 23 (9.5%) patients died of severe irAEs, which consists of 10 patients with pneumonitis, four colitis, four myocarditis, and one each for gastritis, pulmonary embolism, myelosuppression, hypophysitis, and encephalitis. Patients with any irAE onset had significantly longer progression-free survival (PFS) (p = 0.013) and overall survival (OS) (p = 0.007), respectively, than patients without irAEs. In addition, patients with skin toxicities (p = 0.012) or blood toxicities (p = 0.015) had achieved a longer PFS, than those without corresponding toxitities, respectively.ConclusionMost irAEs are mild and manageable, while some irAEs can present at later time or can be life-threatening, especially pneumonitis as we observed. Patients with any irAE onset may achieve a better prognosis than those without irAEs, and presentation of skin or blood toxicities will indicate a better PFS.

Project description:BackgroundWith increased use of immune checkpoint inhibitors (ICIs) among patients with cancer, there is substantial interest in understanding clinical and economic outcomes and management of immune-related adverse events (irAEs).Patients, materials, and methodsA retrospective study was conducted using Premier Healthcare Database, a U.S. national hospital discharge database, from March 1, 2015, through December 31, 2017. The database comprises more than 880 million inpatient and hospital-based outpatient encounters, with more than 200 million unique patients reported by 966 hospitals. Patients with four solid tumors known to benefit from ICI therapy were included. The list of irAEs assessed was defined a priori per American Society of Clinical Oncology clinical guidelines for irAE management. Baseline irAE-related inpatient and outpatient visits were defined as the first inpatient or hospital-based outpatient visit with discharge diagnosis of any irAE of interest following confirmed ICI usage within 90 days prior to the baseline visit. Patients were followed for 90 days after baseline irAE-related inpatient discharge date or outpatient visit date to assess irAE-related inpatient admissions, all-cause in-hospital mortality, ICI reinitiation, and to determine costs and health care resource utilization.ResultsRecords from 673,957 patients with four tumor types were reviewed for ICI therapy. Of 13,030 patients receiving ICIs, approximately 40% experienced at least one irAE, with a total of 10,121 irAEs occurring within 90 days of the ICI visit. The most frequent (>1,000 events) irAEs were anemia, impaired ventricular function with heart failure and vasculitis, thrombocytopenia, thyroid conditions, and peripheral edema. As might be expected, compared with those with baseline irAE-related outpatient visits, patients with baseline irAE-related inpatient visits had a significantly higher percentage of irAE-related inpatient admissions (23% vs. 14%) and all-cause in-hospital mortality (22% vs. 6%) and lower reinitiation of ICI therapy (31% vs. 71%). Baseline irAE-related inpatient visits had significantly higher mean costs ($29,477 vs. $5,718) with longer hospital stays (12.6 vs. 7.8 days).ConclusionFindings from a U.S. national hospital discharge database suggest that irAEs in patients treated with ICIs are common, occur in multiples and with greater frequency in those with pre-existing comorbidities. Those with inpatient admissions have poorer outcomes.Implications for practiceThe present work addressed the knowledge gap in understanding real-world outcomes of immune-related adverse events (irAEs) associated with immune checkpoint inhibitors (ICIs). Patients who experienced irAEs had significantly higher baseline comorbidities and were more likely to have immune-related or immune-compromised comorbid conditions. Patients with baseline irAE-related hospitalizations were more likely to be rehospitalized and to experience in-hospital mortality and less likely to reinitiate ICI treatment. Real-world patients are more diverse than clinical trials, and clinicians should consider both the efficacy and safety profile of ICI treatments, especially for patients with comorbidity conditions. Close monitoring is needed after patients have experienced an irAE.

Project description:Immune checkpoint inhibitors (ICIs) have led recent advances in the field of cancer immunotherapy improving overall survival in multiple malignancies with abysmal prognoses prior to their introduction. The remarkable efficacy of ICIs is however limited by their potential for systemic and organ specific immune-related adverse events (irAEs), most of which present with mild to moderate symptoms that can resolve spontaneously, with discontinuation of therapy or glucocorticoid therapy. Cardiac irAEs however are potentially fatal. The understanding of autoimmune cardiotoxicity remains limited due to its rareness. In this paper, we provide an updated review of the literature on the pathologic mechanisms, diagnosis, and management of autoimmune cardiotoxicity resulting from ICIs and their combinations and provide perspective on potential strategies and ongoing research developments to prevent and mitigate their occurrence.

Project description:Little is known regarding the efficacy of immune checkpoint inhibitors (ICI) in patients with advanced large-cell neuroendocrine lung carcinoma (aLCNEC). 125 consecutive patients with aLCNEC were identified in the electronic databases of 4 participating cancer centers. The patients were divided into group A (patients who received ICI, n=41) and group B (patients who did not receive ICI, n=84). Overall survival since advanced disease diagnosis (OS DX) and OS since ICI initiation (OS ICI) were captured. With a median follow-up of 11.8 months (mo) (IQR 7.5-17.9) and 6.0mo (IQR 3.1-10.9), 66% and 76% of patients died in groups A and B, respectively. Median OS DX was 12.4mo (95% CI 10.7 to 23.4) and 6.0mo (95% CI 4.7 to 9.4) in groups A and B, respectively (log-rank test, p=0.02). For ICI administration, HR for OS DX was 0.59 (95% CI 0.38 to 0.93, p=0.02-unadjusted), and 0.58 (95% CI 0.34 to 0.98, p=0.04-adjusted for age, Eastern Cooperative Oncology Group (ECOG) performance status (PS), presence of liver metastases and chemotherapy administration). In a propensity score matching analysis (n=74; 37 patients in each group matched for age and ECOG PS), median OS DX was 12.5 mo (95% CI 10.6 to 25.2) and 8.4 mo (95% CI 5.4 to 16.9) in matched groups A and B, respectively (log-rank test, p=0.046). OS ICI for patients receiving ICI as monotherapy (n=36) was 11.0 mo (95% CI 6.1 to 19.4). With the limitations of retrospective design and small sample size, the results of this real-world cohort analysis suggest a positive impact of ICI on OS in aLCNEC.

Project description:BackgroundLimited data exist regarding the characteristics and survival outcomes of older adults with non-small cell lung cancer (NSCLC) who receive immune checkpoint inhibitors in routine oncology practice.MethodsUsing the Surveillance, Epidemiology, and End Results-Medicare linked database, we identified 1256 patients aged ≥65 years who were diagnosed with pathologically confirmed stage I to stage IV NSCLC between 2002 and 2015 and initiated nivolumab or pembrolizumab in 2016. We examined patient characteristics and overall survival from the time of immune checkpoint inhibitor initiation through December 31, 2017.ResultsThe median patient age at the time of immune checkpoint inhibitor initiatiton was 75.3 years (interquartile range, 8.5). A substantial percentage of patients were initially diagnosed with stage IV disease (42.6%) and had ≥2 comorbid conditions (48.7%). Using a claims-based proxy, 11.5% of patients had poor performance status and 12.6% had a history of autoimmune conditions. The median overall survival after initiation of immune checkpoint inhibitor was 9.3 months (95% CI, 8.5-10.5 months). The 1-year survival rate was 43.0% (95% CI, 40.2-45.7%). In multivariable analyses, multiple comorbid conditions, squamous histology, a history of nonplatinum doublet systemic therapy, recent radiotherapy, and a shorter time from initial diagnosis to treatment initiation were found to be statistically significantly associated with an increased hazard of death. Demographics, poor performance status, and prior autoimmune conditions were not significantly associated with the hazard of death.ConclusionsMany older adults with NSCLC who initiated immune checkpoint inhibitors had multiple comorbidities, a history of autoimmune disease, or poor performance status. Factors associated with poor prognosis among patients with advanced NSCLC were also associated with worse survival in older adults treated with immune checkpoint inhibitors.

Project description:BackgroundKRAS (Kirsten rat sarcoma viral oncogene homolog) gene mutation is one of the common driver gene mutations in non-small cell lung cancer (NSCLC) with poor prognosis. There are limited effective treatments for advanced NSCLC patients with KRAS mutation. This study aimed to evaluate the effectiveness of PD-1/L1 immune checkpoint inhibitors (ICIs) as a first-line immunotherapy for advanced NSCLC patients harboring KRAS oncogene mutation.MethodsThis multicenter retrospective real-world study was conducted from 2019 to 2024 at Shanghai Changzheng Hospital and Shanghai Municipal Hospital of Traditional Chinese Medicine, including 78 patients who received immunotherapy using PD-1/L1 ICIs, and 29 patients who received traditional platinum-doublet chemotherapy. The primary endpoints were progression-free survival (PFS) and overall survival (OS). The secondary endpoints included the objective response rate (ORR), disease control rate (DCR), and correlation of prognostic biomarkers with survival outcomes.ResultsNo significant difference in ORR and DCR was observed between the two groups. The median PFS in immunotherapy group was longer than that in chemotherapy group [7.9 months (95% CI: 5.3-10.5) vs. 6.0 months (95% CI: 3.8-8.2), P = 0.030], and there was no significant difference in OS between the two groups (16.2 vs. 19.2 months, P > 0.05). Multivariate analysis identified PD-L1 expression as an independent protective factor for PFS (HR = 0.397, 95% CI: 0.178-0.887, P = 0.024), and elevated CRP (HR = 1.005, 95% CI: 1.001-1.010, P = 0.022), CEA (HR = 1.008, 95% CI: 1.001-1.014, P = 0.030) and neutrophil-to-lymphocyte ratio (NLR) (HR = 1.105, 95% CI: 1.024-1.193, P = 0.010) were independent risk factors for progression.ConclusionThe first-line treatment with PD-1/PD-L1 ICIs showed numerically better clinical efficacy than the traditional double-agent chemotherapy in patients with KRAS-mutated NSCLC, especially in PFS. Additionally, PD-L1 expression, C reactive protein, CEA, and NLR could serve as markers for predicting the efficacy of immunotherapy in patients with KRAS-mutated NSCLC.
