Immune-Related Adverse Events and Immune Checkpoint Inhibitor Efficacy in Patients with Gastrointestinal Cancer with Food and Drug Administration-Approved Indications for Immunotherapy.

ABSTRACT: INTRODUCTION:Immune-related adverse event (IRAE) onset may represent a clinical biomarker for anti-programmed cell death protein 1 (PD-1) antibody response based on emerging evidence from patients with various advanced malignancies. This phenomenon has not been previously reported in a multidisease cohort of patients with gastrointestinal (GI) cancer with Food and Drug Administration (FDA)-approved indications to receive immune checkpoint inhibitor therapy. MATERIALS AND METHODS:The study was a multicenter retrospective cohort analysis of 76 patients with GI cancer who had received anti-PD-1 antibodies for FDA-approved indications. The primary and secondary outcomes of the study were progression-free survival (PFS) and overall survival (OS) in patients based upon IRAE presence, respectively. PFS and OS were estimated by the Kaplan-Meier method; a Cox proportional-hazards model adjusted for IRAE onset, patient age, and enrolling institution was used to analyze outcomes. RESULTS:Median PFS and OS were prolonged in patients who experienced IRAEs compared with those who did not experience them (PFS: not reached [NR] vs. 3.9 months [hazard ratio (HR) 0.13, 95% confidence interval (CI) 0.05-0.3, p < .001]; OS: NR vs. 7.4 months [HR 0.11, 95% CI 0.03-0.36, p < .001]). Among patients who experienced IRAEs, there were no significant differences in PFS and OS by either initial IRAE severity, management, or time to onset. CONCLUSION:Patients with gastrointestinal cancer who experienced IRAEs while on anti-PD-1 antibodies demonstrated significant improvements in PFS and OS compared with their counterparts who did not develop IRAEs. Although these findings add to results from studies in other tumor types, larger prospective studies are needed prior to clinical adoption of IRAE onset as a biomarker for immune checkpoint inhibitor response. IMPLICATIONS FOR PRACTICE:Predictive clinical biomarkers for immune checkpoint inhibitor response have been understudied in the field of immuno-oncology. Immune-related adverse event onset appears to be one such biomarker. Across tumor types, immune-related adverse event onset has been associated with response to anti-programmed cell death protein 1 (PD-1) antibodies. The results of this study demonstrate this for the first time in patients with gastrointestinal cancer receiving anti-PD-1 antibodies. Before immune-related adverse event onset can be adopted clinically as a predictive biomarker for immune checkpoint inhibitor response, however, larger prospective studies are needed to better understand the nuances between immune-related adverse event characteristics (severity, site, management, timing of onset) and immune checkpoint inhibitor effectiveness.

Project description:BACKGROUND:Immune-checkpoint inhibitors (ICIs) emerged as a novel class of drugs for the treatment of a broad spectrum of malignancies. ICIs can produce durable antitumor responses but they are also associated with immune-related adverse events (irAEs). Endocrinopathies have reported as one of the most common irAEs of ICIs. METHODS:This study aimed to quantify association of endocrine adverse events (AEs) and ICI therapy and also to characterize the profiles of ICI-related endocrine complications from real-world practice. Data from the first quarter of 2014 to first quarter of 2019 in FDA Adverse Event Reporting System (FAERS) database were gathered to conduct disproportionality analysis. The definition of endocrine AEs relied on the preferred terms (PTs) provided by the Medical Dictionary for Regulatory Activities (MedDRA). Two signal indices based on statistical shrinkage transformation, reporting odds ratios (ROR) and information component (IC), were used to evaluate correlations between ICIs and endocrine events. For ROR, it was defined a signal if the lower limit of the 95% confidence interval (ROR025) more than one, with at least 3 cases. For IC, lower end of the 95% confidence interval of IC (IC025) exceeding zero was deemed statistically significant. RESULTS:A total of 29,294,336 records were involved, among these 6260 records related to endocrine AEs after ICIs treatment were identified. In general, male had a slightly lower reporting frequencies for ICIs-related endocrinopathies compared with female but not significant (ROR = 0.98 95%CI: 0.93-1.04) and the difference varied in several common endocrine AEs. Notably, in general, ICI drugs were significantly associated with over-reporting frequencies of endocrine complications, corresponding to IC025 = 2.49 and ROR025 = 5.99. For monotherapy, three strategies (anti-PD-1, anti-PD-L1 and anti-CTLA-4) were all associated with significant increasing endocrine events. Different reporting frequencies emerged when anti-CTLA-4 therapy was compared with anti-PD-1/PD-L1 medications for endocrine toxicities, corresponding to ROR = 1.68 (95%CI 1.55-1.83), ROR = 2.54 (95%CI 2.20-2.93), respectively. Combination therapy was associated with higher risk of endocrinopathies compared with monotherapy (ROR = 2.00, 95%CI 1.89-2.11). When further analysis, the spectrum of endocrine AEs differed in immunotherapy regimens. Hypothyroidism (N = 885,14.14%), adrenal insufficiency(N = 730,11.66%), hypophysitis (N = 688,10.99%) and hyperthyroidism (N = 472,7.54%) were top 4 ranked endocrine events after ICI therapy and their reporting frequency also differed in ICI immunotherapies. CONCLUSION:Our pharmacovigilance analysis shows a high reporting frequency of endocrine AEs provoked by ICI monotherapy (especially anti-CTLA-4 therapy) and further reinforced by combination therapy. In addition, treatment with different ICI immunotherapies may result in a unique and distinct profile of endocrinopathies. Early recognition and management of ICI-related endocrine irAEs is of vital importance in clinical practice.

Project description:BackgroundAlthough arrhythmias have been reported in patients treated with immune checkpoint inhibitors (ICIs), the association between arrhythmias and ICIs has not been thoroughly evaluated in real-world studies. We aimed to describe the major features of ICI-related arrhythmic events and identify the factors that contributed to death.MethodsA disproportionality analysis was performed using data from the Food and Drug Administration Adverse Event Reporting System (FAERS) database from January 2011 to December 2021. Reporting odds ratios (RORs), proportional reporting ratio and information component were used to assess whether adverse arrhythmic events were associated with ICIs. The clinical characteristics of patients with ICI-associated arrhythmias were compared with fatal and non-fatal arrhythmias. The time to onset (TTO), fatality rates of arrhythmic events were also investigated.ResultsWe identified a total of 1945 cases of ICI-related arrhythmic events. Men (64.78%) were identified significantly more frequently than women (28.84%). The median age was 68 years ([interquartile range, IQR] 60-75 years). Anti-programmed cell death-1 (PD-1) and anti-programmed cell death ligand-1 (PD-L1) were associated with adverse arrhythmic events, corresponding to ROR 1.11 (95% confidence interval [CI] 1.05-1.17) and ROR 1.34 (95% CI 1.20-1.49), respectively. However, anti-cytotoxic T-lymphocyte associated protein 4 or combination immunotherapy did not appear to be associated with arrhythmic events. Atrial fibrillation (N = 576, 0.62%), cardiac arrest (N = 284, 0.31%), tachycardia (N = 175, 0.19%) were the most common adverse arrhythmic events. Sudden death and complete atrioventricular block are adverse events that are significantly associated with ICI-related arrhythmic events and have strong signal intensity. The TTO of cases that resulted in death (30 days [IQR] 11-73.75) was significantly earlier than that of cases that did not result in death (33 days [IQR 10.5-88.5], p = 0.003). ICI-related arrhythmic events were severe with death occurring in 507 (26.07%) of 1945 arrhythmias cases.ConclusionsTreatment with PD-1/PD-L1 may cause arrhythmic events, which are severe and tend to occur early on during treatment. It is important to identify ICI-related arrhythmias as early as possible, and to manage them appropriately.
