Cardiovascular safety of the glucagon-like peptide-1 receptor agonist taspoglutide in people with type 2 diabetes: an individual participant data meta-analysis of randomized controlled trials.

To study the short-term cardiovascular effects of the once-weekly glucagon-like peptide-1 receptor agonist taspoglutide. We conducted a meta-analysis of individual-participant data from nine randomized controlled trials in the T-Emerge programme, which assessed the efficacy and safety of taspoglutide in type 2 diabetes. Our primary outcome was a composite of death from cardiovascular disease (CVD) and acute myocardial infarction, stroke and hospitalization for unstable angina. Overall, 7056 individuals were included in the analysis, and there were 67 primary endpoint events during 7478 person-years of follow-up (40 vs 27 events in the intervention vs control groups, respectively). The odds ratio for the composite endpoint among people randomized to taspoglutide was 0.94 (95% confidence interval 0.57-1.56), which was robust across multiple subgroups. Longer-term data were not available as the development of taspoglutide was stopped because of gastrointestinal intolerance and serious hypersensitivity reactions. The available data suggest that short-term, once-weekly administration of taspoglutide was not associated with an excess risk of CVD, and provide insights relevant to the development of other novel once-weekly incretin mimetics.
