Studies & key findings

  • The SCALE Obesity trial (NEJM 2015, n=3,731) demonstrated that liraglutide 3.0 mg as Saxenda produced a mean 8.4% body weight reduction vs 2.8% with placebo over 56 weeks — with 63.2% of participants achieving ≥5% weight loss, leading to FDA approval for chronic weight management.
  • The LEADER cardiovascular outcomes trial (NEJM 2016, n=9,340) showed liraglutide 1.8 mg significantly reduced the MACE composite endpoint by 13% (HR 0.87, p=0.01) in T2D patients at high cardiovascular risk over a median 3.8 years — establishing the first cardiovascular mortality benefit for a GLP-1 agonist.
