RESUMEN
AIM: To assess the relationship between weight change and glycated haemoglobin (HbA1c) change in dulaglutide-treated patients by analysing data from six head-to-head phase III AWARD clinical trials. METHODS: At 26 weeks, the relationship between weight and HbA1c was analysed in each trial rather than by pooling data because of differences in design and background therapy. The effect of baseline characteristics was also evaluated with regard to weight and HbA1c response. RESULTS: Across the studies, 87-97% and 83-95% of patients treated with dulaglutide 1.5 and 0.75 mg, respectively, had reductions in HbA1c levels, while 57-88% and 43-84% of patients treated with dulaglutide 1.5 and 0.75 mg, respectively, experienced weight loss. The majority (55-83%) of patients receiving dulaglutide 1.5 mg experienced weight loss and HbA1c reductions, while 41-79% of patients in the dulaglutide 0.75 mg arm lost weight and had reductions in HbA1c level. A weak and inconsistent correlation was observed between the changes in weight and HbA1c (range from -0.223 to 0.267) in patients treated with dulaglutide. The baseline characteristics of gender, age, duration of diabetes, HbA1c, body weight and BMI were not related to different combinations of weight and HbA1c responses. CONCLUSIONS: Dulaglutide is an effective treatment option across the type 2 diabetes treatment spectrum. Dulaglutide showed dose-dependent effects on both weight loss and HbA1c reduction. These effects had a weak correlation and appeared to be independent.

AIMS: To assess whether early measures of fasting blood glucose predict later glycaemic response with once-weekly dulaglutide in patients with Type 2 diabetes mellitus. METHODS: Post hoc analyses were conducted separately for two phase 3 studies (AWARD-5 and AWARD-1) in patients assigned to once-weekly dulaglutide. Week 2 fasting blood glucose was used as a predictor variable, and glycaemic treatment response was defined by HbA1c response based on a composite efficacy endpoint. The association between fasting blood glucose and the glycaemic response was analysed using chi-square tests. RESULTS: There was a strong association between fasting blood glucose < 7.9 mmol/l at week 2 and achieving the HbA1c composite efficacy endpoint at week 26 (P < 0.01). Higher fasting blood glucose at week 2, however, did not predict absence of glycaemic response and requires further assessment. CONCLUSIONS: Fasting blood glucose measured at 2 weeks may be an early and useful predictor of glycaemic response to once-weekly dulaglutide treatment.
