420-P: Efficacy and Safety of Glucagon-Like Peptide-1 Receptor Agonists: A Systematic Review and Meta-analysis

Abstract

Background: Several large randomized trials suggest GLP-1RAs may reduce mortality in addition to lowering A1c in patients with T2D. Treatment algorithms from the ADA/EASD now recommend a GLP-1RA be initiated in patients with T2D who either have or are at high risk of atherosclerotic cardiovascular (CV) disease, regardless of A1c level. To better quantify the efficacy and safety of GLP-1RAs, we conducted a systematic review and meta-analysis of all randomized trials of this drug class. Methods: We searched PubMed and Scopus (inception to June 2019) for randomized trials of at least 52 weeks duration enrolling adults with T2D that compared GLP-1RAs with placebo. Outcomes included microvascular/macrovascular complications, mortality, change in cardiovascular risk factors, and adverse events. Continuous outcomes were calculated with standardized mean differences, and binary outcomes were calculated using odds ratios. Pooled analyses were performed with fixed and random effects models. Heterogeneity was assessed using the I2 statistic. Results: See Table for results. Conclusions: Patients with T2D who received GLP-1RAs when compared to placebo had a significantly lower rate of major adverse CV events and A1c. These findings support the current ADA/EASD treatment recommendations. Subsequent cost effectiveness analyses will help further inform healthcare policy decisions. Disclosure J. Alexander: None. E.M.
