Trulicity® (dulaglutide): Effect on Blood Pressure

Detailed information

A phase 2, multicenter, randomized, double-blind, placebo-controlled study assessed the effects of once-weekly dulaglutide 1.5 mg and dulaglutide 0.75 mg on BP in 755 patients who had T2DM with or without hypertension. The primary endpoint was change from baseline at 16 weeks in mean 24-hour SBP.¹

The treatment effects of dulaglutide on SBP were evident at 4 weeks.¹

In comparison with placebo, dulaglutide 1.5 mg significantly reduced 24-hour SBP by approximately 3 mmHg at 16 and 26 weeks.¹

Dulaglutide 1.5 mg and dulaglutide 0.75 mg both demonstrated noninferiority to placebo in LSM change from baseline in 24-hour SBP.¹

Dulaglutide 1.5 mg also demonstrated superiority to placebo in lowering SBP at both 16 (p≤ 0.001) and 26 weeks (p=.002).¹

The change in SBP from baseline to 16 weeks with dulaglutide 0.75 mg achieved the primary objective of noninferiority to placebo (p< 0.001).¹

There was no significant difference in DBP.¹

Changes from baseline in ambulatory SBP and DBP can be seen in Table 1.
