Key clinical point: Tirzepatide. at doses of 10 or 15 mg, vs. 2 mg semaglutide was associated with a significantly greater reduction in glycated hemoglobin (A1c) levels and body weight in patients with type 2 diabetes (T2D). Both drugs had a similar overall safety profile.
Major finding: At week 40 , 10 and 15 mg tirzepatide vs. 2 mg semaglutide led to a significantly greater reduction in A1c levels (estimated treatment difference [ETD] −0.36%; P = .008, and ETD −0.4%; P = .003, respectively) and body weight (ETD −3.15 and −5.15 kg, respectively; both P < .001).
Study details: This was an adjusted indirect treatment comparison study that included patients with T2D from the SURPASS-2 (n = 1879) and SUSTAIN FORTE (n = 961) trials who were randomly assigned to receive tirzepatide or injectable semaglutide.
