Aims: To compare patient-reported outcomes and clinical outcomes in patients who initiated dulaglutide or liraglutide as part of usual clinical therapy.
Methods: This observational study enrolled adults with type 2 diabetes who initiated dulaglutide or liraglutide between April 2017 and January 2018. A prospective patient cohort completed questionnaires at baseline and at their usual follow-up visit three to six months later. Clinical outcomes were assessed in a post-hoc retrospective analysis using propensity score matching.
Results: In the per-protocol analysis, 146 dulaglutide and 79 liraglutide patients had similar significant improvements in diabetes treatment satisfaction scores (dulaglutide 9.6 ± 1.1, p < 0.001; liraglutide 10.6 ± 1.4, p < 0.001) and follow-up scores for diabetes device satisfaction. Only dulaglutide had significant improvements in medication adherence scores. In the overall cohort, 754 matched patients showed similar reductions in A1C (dulaglutide -0.8% [9 mmol/mol]; liraglutide -0.7% [8 mmol/mol]). Liraglutide patients had a greater reduction in weight than those initiating dulaglutide (-2.8 kg vs. -1.8 kg; p < 0.001).
Conclusions: Patients who initiated dulaglutide or liraglutide in a real-world specialist practice had similar improvements in diabetes medication satisfaction and diabetes device satisfaction. Only dulaglutide patients had significant improvements in medication adherence scores. Both treatment cohorts had similar patterns of A1C change, and liraglutide had significantly greater weight loss, which are similar to findings from clinical trials.
