SOURCE-LINKED STUDY SUMMARY
Liraglutide once a day versus exenatide twice a day for type 2 diabetes: a 26-week randomised, parallel-group, multinational, open-label trial (LEAD-6).
What was studied?
LEAD-6 was a randomized, open-label human trial comparing liraglutide with exenatide. The primary outcome was change in HbA1c, a measure of longer-term blood glucose.
What changed?
HbA1c fell 1.12 versus 0.79 percentage points. Weight loss was similar. Liraglutide caused less persistent nausea and fewer minor low-glucose events, but controlled glucose after breakfast and dinner less effectively. Two exenatide-plus-sulphonylurea patients had major low-glucose episodes.
Who was studied?
Adults had inadequately controlled type 2 diabetes despite metformin, a sulphonylurea, or both; 233 received liraglutide and 231 exenatide.
Studied exposure
For 26 weeks, added treatment was liraglutide 1.8 mg daily or exenatide 10 micrograms twice daily.
What remains uncertain?
Treatment was open-label and lasted 26 weeks. No author-stated limitation was available in this abstract.
