Randomized, placebo-controlled trials of the glucagon-like peptide-1 (GLP-1) receptor agonists have provided strong evidence to support their use โ in fact, they have presaged a mini-revolution in how type 2 diabetes is managed. ๐ https://www.nejm.org/doi/full/10.1056/NEJMra2500106
Tirzepatide was the first dual GLP-1 and glucose-dependent insulinotropic peptide receptor agonist approved for the treatment of type 2 diabetes on the basis of the SURPASS-1 (Tirzepatide [LY3298176] in Participants with Type 2 Diabetes Not Controlled with Diet and Exercise Alone) trial, a randomized, placebo-controlled trial of tirzepatide (administered in weekly doses of 5 mg, 10 mg, or 15 mg) paired with metformin for treatment of type 2 diabetes (seen in figure). Tirzepatide reduced glycated hemoglobin levels by as much as 2 percentage points and was superior to placebo at all dose levels. At 40 weeks, nearly 90% of participants had glycated hemoglobin levels of less than 7.0%, a change that was associated with profound weight loss.
