Pre-Existing Cardiovascular Conditions as Clinical Predictors of Myocarditis Reporting with Immune Checkpoint Inhibitors: A VigiBase Study.

ABSTRACT: Although rare, immune checkpoint inhibitor (ICI)-related myocarditis can be life-threatening, even fatal. In view of increased ICI prescription, identification of clinical risk factors for ICI-related myocarditis is of primary importance. This study aimed to assess whether pre-existing cardiovascular (CV) patient conditions are associated with the reporting of ICI-related myocarditis in VigiBase, the WHO global database of suspected adverse drug reactions (ADRs). In a (retrospective) matched case-control study, 108 cases of ICI-related myocarditis and 108 controls of ICI-related ADRs other than myocarditis were selected from VigiBase. Drugs labeled as treatment for CV conditions (used as a proxy for concomitant CV risk factors and/or CV diseases) were found to be associated more strongly with the reporting of ICI-related myocarditis than with other ICI-related ADRs (McNemar's chi-square test of marginal homogeneity: p = 0.026, Cramer's coefficient of effect size: ? = 0.214). No significant association was found between pre-existing diabetes and ICI-related myocarditis reporting (McNemar's test of marginal homogeneity: p = 0.752). These findings offer an invitation for future prospective pharmacoepidemiological studies to assess the causal relationship between pre-existing CV conditions and myocarditis onset in a cohort of cancer patients followed during ICI treatment.

Project description:BackgroundPatients with pre-existing autoimmune disease (AD) have been largely excluded from clinical trials of immune checkpoint inhibitors (ICI), so data on safety of ICIs among patients with pre-existing AD are relatively limited. There is a need for deeper understanding of the type and management of complications from ICI in patients with pre-existing AD. We sought to investigate the safety of ICIs in patients with pre-existing ADs as well as factors associated with AD flare.MethodsConsecutive patients with pre-existing AD who received monotherapy as well as combination of ICI therapies at our institution from September 2015 through September 1st, 2018 were identified. Clinical information was abstracted via manual chart review. Clinical factors associated with AD flare were determined using multivariable logistic regression.ResultsA total of 42 patients were identified of whom 12 developed AD flare. All flares were treated with oral or topical corticosteroids, while a patient with flare of rheumatoid arthritis was treated with tofacitinib and another patient with Crohn's flare was treated with infliximab. Female sex, smoking status, higher age at the start of ICI therapy, cancer type, such as melanoma and lung cancer as compared to other cancers, were not significantly associated with AD flare, however, patients with underlying rheumatologic AD were noted to have a five times greater likelihood of flare as compared to other non-rheumatologic AD. Nine patients developed new immune related adverse events (IRAEs) unrelated to underlying AD, such as inflammatory poly-arthropathy, neuropathy, hypothyroidism, diarrhea, lichenoid drug eruptions, which were managed with oral and/or topical corticosteroids. ICI was stopped in six patients due to AD flare, in four patients due to IRAE flare (out of which one resumed ICI after resolution of IRAE).ConclusionsIn patients with pre-existing AD treated with ICI, AD flare occurred in 28% of patients and were managed successfully with corticosteroids alone or with additional disease-modifying therapies. ICI could be considered in patients with AD, but with very close monitoring and preemptive multidisciplinary collaboration.

Project description:BackgroundThyroid dysfunction is among the most common autoimmune diseases and immune checkpoint inhibitor (ICI)-induced immune-related adverse events (irAE). We determined the association between longitudinal thyroid function and clinical outcomes in patients treated with ICI.MethodsWe identified all patients treated with ICI at UT Southwestern Medical Center from January 1, 2011, through December 31, 2020. We defined normal thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels according to institutional reference range. We defined clinical thyroid dysfunction using established criteria incorporating labs and treatment. We determined the association between thyroid function and overall survival (OS) using Kaplan-Meier curves, log-rank tests, and multivariate Cox proportional hazards model.ResultsA total of 1781 patients were included in analyses, of whom 381 (21%) had abnormal baseline TSH. Patients with abnormal baseline TSH were more likely to be female, have kidney cancer, and initiate levothyroxine after ICI initiation (all P < 0.001). Patients with abnormal baseline TSH had inferior OS (median 16 vs 27 months; P < 0.001). Among patients with normal baseline TSH, those who had abnormal TSH after ICI initiation had improved OS (median 41 vs 22 months; P < 0.001). In a multivariate Cox model, abnormal baseline TSH was associated with worse OS (HR 1.62; 95% CI, 1.30-2.02; P < 0.001), while initiation of levothyroxine after ICI initiation was associated with improved OS (HR 0.62; 95% CI, 0.44-0.88; P = 0.008).ConclusionsICI-induced thyroid dysfunction is associated with improved survival, although abnormal TSH prior to ICI initiation is associated with inferior survival.PrecisThyroid abnormalities occur commonly in the general population and as immunotherapy toxicities. We found that immunotherapy-induced thyroid dysfunction is associated with better survival, but pre-existing thyroid abnormalities convey worse outcomes.
