Comparative effectiveness of exenatide once-weekly versus liraglutide in routine clinical practice: A retrospective multicentre study and meta-analysis of observational studies.

ABSTRACT: In this study, we retrospectively compared the effectiveness of exenatide once-weekly (ExeOW) versus liraglutide in non-insulin treated patients with type 2 diabetes followed under routine care. We also present a meta-analysis of similar observational studies available in the literature. In our multicentre retrospective study, patients initiating ExeOW (n = 204) or liraglutide (n = 410) had similar baseline clinical characteristics. Change in HbA1c at 6 months was superimposable in the two groups (-0.7% ± 1.0%), and changes in body weight were also similar (ExeOW -2.2 ± 3.7 kg; liraglutide -2.5 ± 4.3 kg; p = 0.457). Discontinuation rates were numerically but not significantly lower for ExeOW versus liraglutide. Pooling these data with those of observational studies available in the literature yielded superimposable effects between the two groups for the change in HbA1c and body weight, with a higher risk of discontinuation (mainly based on pharmacy refill rates) for ExeOW. We conclude that, in patients under routine care, initiation of ExeOW provides similar benefits on HbA1c and body weight as initiation of liraglutide. These data help view the results of randomized controlled trials from the perspective of their application in routine clinical practice.
