Abstract

Aim: To evaluate the cardiovascular (CV) efficacy of liraglutide and semaglutide in patients with type 2 diabetes (T2D) and peripheral artery disease (PAD).

Materials and methods: LEADER and SUSTAIN 6 trials investigated subcutaneous liraglutide (≤1.8 mg/day) and semaglutide (0.5 or 1.0 mg/week), respectively, versus placebo in patients with T2D and high CV risk (median follow-up: 3.8 and 2.1 years, respectively). The primary outcome was a composite of CV death, non-fatal myocardial infarction or non-fatal stroke (major adverse CV event [MACE]) according to the presence of PAD at baseline.

Results: Overall, 1184/9340 (12.7%) patients in LEADER and 460/3297 (14.0%) in SUSTAIN 6 had PAD at baseline. Patients with PAD were at an ~35% increased risk of MACE versus those without (LEADER: hazard ratio [HR] 1.36, 95% confidence interval [CI] 1.17-1.58; SUSTAIN 6: HR 1.33, 95% CI 0.94-1.83). The effects of both therapies on MACE were consistently beneficial in patients with PAD (liraglutide: HR 0.77, 95% CI 0.58-1.01; semaglutide: 0.61, 0.33-1.13) and without (liraglutide: HR 0.89, 95% CI 0.79-1.00; semaglutide: HR 0.77, 95% CI 0.58-1.01; Pinteraction = .34 for liraglutide and .49 for semaglutide). Absolute risk reductions for MACE were higher in patients with PAD (liraglutide: 4.13%-point, 95% CI -0.15-8.42; semaglutide: 4.63%-point, 95% CI -0.58-9.84) versus without (liraglutide:1.42%-point, 95% CI -0.03-2.87; semaglutide: 1.90%-point, 95% CI 0.00-3.80).

Conclusion: Both liraglutide and semaglutide reduce MACE with consistent CV efficacy regardless of PAD status.
