Glucagon-like Peptide-1 Agonists Reduce Cardiovascular Events in Cancer Patients on Immune Checkpoint Inhibitors
Abstract
Background: Immune checkpoint inhibitors (ICIs) are associated with an increased risk of major adverse cardiovascular events (MACE). Glucagon-like peptide-1 agonists (GLP1a), initially developed for type 2 diabetes mellitus (T2DM), have shown promising results in reducing cardiovascular events. We aimed to investigate the effect of GLP1a on cardiovascular events in patients receiving ICIs.
Methods: We conducted a retrospective, propensity score-matched cohort study using the TriNetX database. We identified adults with cancer and T2DM who received ICIs between April 2013 and May 2023. The primary efficacy outcome was incident MACE, defined as a composite of myocardial infarction, need for coronary revascularization, heart failure, ischemic stroke, and cardiac arrest. The secondary efficacy outcomes were the individual components of MACE as well as myocarditis and pericarditis. Safety outcomes included the occurrence of immune-related adverse events, serious adverse events related to GLP1a use, and all-cause mortality.
Results: We identified 7651 patients eligible for inclusion, among which 479 received GLP1a and 7172 received non-GLP1a diabetes medications. After matching (469 patients each), baseline characteristics were well-balanced. Over a median 12-month follow-up, the GLP1a cohort had a significantly lower MACE incidence than the non-GLP1a cohort (9.0 vs. 17.1 events per 100 patient-years) with a 54 % lower risk of MACE (Hazard ratio (HR),0.46 [95 % CI: 0.32-0.67]). There were reductions in myocardial infarction or need for coronary revascularization, heart failure, and all-cause mortality, with no differences in other cardiovascular events. GLP1a use did not increase risk of adverse events, including pancreatitis, biliary disease, bowel obstruction, gastroparesis, and immune-related adverse events.
Conclusion: GLP1a use in cancer patients with T2DM receiving ICIs was associated with reduced MACE and all-cause mortality without an increased risk in serious adverse events.
