Exenatide once weekly for the treatment of type 2 diabetes mellitus: clinical results in subgroups of patients using different concomitant medications
Abstract
OBJECTIVE: In this pooled analysis, the efficacy and tolerability of exenatide once weekly (EQW) in patients categorized by baseline concomitant glucose-lowering therapy were evaluated.
METHODS: This post hoc analysis included data from the intent-to-treat populations of 7 randomized controlled trials in which patients with type 2 diabetes mellitus were treated with EQW for 24 to 30 weeks. Patients were classified into subgroups on the basis of their baseline glucose-lowering therapy: diet and exercise only, metformin (MET) only, MET + sulfonylurea (SU), SU ± other (thiazolidinedione [TZD] only or MET + TZD), or TZD ± MET. Changes from baseline in key efficacy endpoints and tolerability were analyzed by baseline concomitant glucose-lowering therapy group.
RESULTS: A total of 1719 patients were included. Treatment with EQW was associated with significant improvements from baseline in glycated hemoglobin levels, fasting glucose levels, and body weight in all of the groups. There were significant decreases from baseline for both systolic blood pressure and diastolic blood pressure in the MET and MET + SU groups, and a significant decrease in systolic blood pressure in the diet and exercise group. Lipid profiles generally improved in the diet and exercise, MET only, MET + SU, and TZD ± MET groups. Overall, the most frequent adverse events with EQW treatment, other than hypoglycemia, were nausea (14.7%), diarrhea (10.9%), and nasopharyngitis (7.2%). There was a higher incidence…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 1,719 participants or records.
