Once-Weekly Exenatide in Youth With Type 2 Diabetes.

OBJECTIVE

Approved treatments for type 2 diabetes in pediatric patients include metformin, liraglutide, and insulin. However, approximately one-half of the youth fail metformin monotherapy within 1 year, insulin therapy is associated with challenges, and liraglutide requires daily injections. Consequently, the efficacy and safety of once-weekly injections of exenatide for the treatment of youth with type 2 diabetes was evaluated.

RESEARCH DESIGN AND METHODS

Participants (aged 10 to <18 years) were randomized (5:2) to once-weekly exenatide 2 mg or placebo, respectively. The primary efficacy end point was change in glycated hemoglobin from baseline to week 24. Secondary efficacy end points were also evaluated, and the frequency of adverse events (AEs) was assessed.

RESULTS

A total of 83 participants were randomized (exenatide, 59; placebo, 24) and 72 completed 24-week treatment (exenatide, 49; placebo, 23). At 24 weeks, the least squares mean change in glycated hemoglobin was -0.36% for the exenatide and +0.49% for the placebo groups (between-group difference, -0.85%; 95% CI -1.51, -0.19; P = 0.012). Nonsignificant least squares mean differences from baseline to 24 weeks favoring exenatide were observed: fasting glucose -21.6 mg/dL (-49.0, 5.7; P = 0.119), systolic blood pressure -2.8 mmHg (-8.0, 2.4; P = 0.284), and body weight -1.22 kg (-3.59, 1.15; P = 0.307). AEs occurred in 36 (61.0%) and 17 (73.9%) participants in the exenatide and placebo groups, respectively.

CONCLUSIONS

In youth with type 2 diabetes suboptimally controlled with current treatments, once-weekly exenatide reduced glycated hemoglobin at 24 weeks and was well tolerated.
