Published in the prestigious NEJM (New England Journal of Medicine) in 2015, the Satiety and Clinical Adiposity — Liraglutide Evidence in Nondiabetic and Diabetic Individuals (SCALE) Obesity and Prediabetes Study, or “SCALE study”, was a multicenter randomised controlled trial which ran from June 1, 2011, through March 18, 2013, at 191 sites in 27 countries in Europe, North America, South America, Asia, Africa, and Australia. 3731 patients aged above 18 years old with BMI above 27 (average BMI 38 average weight 106kg) were recruited for this 56 week study.

Reduced rate of prediabetes, diabetes, hypertension, high cholesterol in Saxenda group.
Safety: most common adverse effect was nausea, vomiting and diarrhoea in the Saxenda group which was typically mild and resolved after several weeks, <5% of subjects needed to discontinue the medication due to side effects
