Expanded dulaglutide weekly doses at par with 1.5 mg dose in type 2 diabetes with CVD risk: Study
USA: Findings from a post-analysis of the AWARD-11 study have suggested similar favorable effects of dulaglutide 3.0 mg and 4.5 mg on several cardiometabolic CVD risk factors, if not greater than dulaglutide 1.5 mg in diabetics with increased CVD risk.

USA: Findings from a post-analysis of the AWARD-11 study have suggested similar favorable effects of dulaglutide 3.0 mg and 4.5 mg on several cardiometabolic CVD risk factors, if not greater than dulaglutide 1.5 mg in diabetics with increased CVD risk.
The data, published in Diabetes, Obesity and Metabolism, support the hypothesis that the effects of once-weekly higher dulaglutide doses of 3.0 and 4.5 mg on CVD risk are consistent with those established for the 1.5 mg dose in REWIND.
David A. Cox, Eli Lilly and Company, Indianapolis, Indiana, USA, and colleagues conducted this post hoc analysis with the objective to investigate the effect of dulaglutide on cardiovascular disease (CVD) risk factors in subgroups of participants at increased CVD risk in the AWARD-11 study.
For this purpose, the researchers categorized patients who received once-weekly dulaglutide 1.5, 3.0, or 4.5 mg for 52 weeks according to their Framingham CVD risk category [low (N = 295), medium (N = 481), and high (N = 1054) risk], and their baseline CVD risk according to the REWIND study eligibility criteria (N = 953).
Assessment of serum lipids and vital signs were done at baseline and at 52 weeks. Data analysis was done as least squares mean percentage change from baseline for lipids and least squares mean change from baseline for vital signs.
Based on the study, the researchers reported the following:
- Demographic and baseline clinical characteristics were balanced across doses within the CVD risk groups.
- In the high Framingham CVD risk and REWIND-like groups, dulaglutide resulted in dose-related decreases in total cholesterol (≤6.0%), non-high-density lipoprotein cholesterol (≤8.8%), very-low-density lipoprotein cholesterol (≤19.4%) and triglycerides (≤21.5%), with little change in low-density lipoprotein cholesterol and high-density lipoprotein cholesterol.
- Systolic and diastolic blood pressure decreased up to 5.6 mmHg and 1.6 mmHg, respectively, and heart rate increased up to 2 beats/min.
The researchers wrote, "these data support the hypothesis that higher dulaglutide doses of 3.0 and 4.5 mg once weekly may have effects on CVD risk consistent with those established for the 1.5 mg dose in REWIND to the extent that improvements in body weight, serum lipids, glycaemic control, and systolic blood pressure may contribute to MACE risk reduction with GLP-1 RAs."
