Head-to-head evidence
dulaglutide vs liraglutide
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

NCT01394952 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial involving 9,901 participants. The hard clinical primary endpoint was met: 594 dulaglutide participants versus 663 placebo participants experienced a composite cardiovascular event, with a hazard ratio of 0.88 (p=0.026).

NCT00318461 · Phase 3 · completed
This was a large (n=1091), randomized, double-blind, parallel-group trial with both a placebo-controlled comparison (liraglutide + metformin vs metformin + liraglutide placebo) and an active-controlled comparison (glimepiride + metformin). The primary endpoint was change in HbA1c at week 26, a hard, regulator-accepted outcome for type 2 diabetes. The prespecified primary comparisons for liraglutide 1.2 mg and 1.8 mg/day were met: both were significantly superior to metformin alone (p<0.0001) and non-inferior to glimepiride + metformin within the 0.4% margin. The 0.6 mg dose was superior to metformin but did not meet non-inferiority against glimepiride + metformin, which does not negate the positive results for the clinically relevant doses.
Next expected readout: June 2027 · NCT03883412 (registry estimate)
