Abstract #OR15-1

Findings from the first phase 3a clinical trial for semaglutide, an investigational glucagon-like peptide-1 (GLP-1) analogue, demonstrated that treatment with semaglutide administered once-weekly, significantly improved glycaemic control compared to placebo in adults with type 2 diabetes previously managed with diet and exercise alone. Results from the SUSTAIN 1 trial were presented today at the Endocrine Society's 98th Annual Meeting and Expo (ENDO 2016) in Boston, MA, US.[1]

The 30-week SUSTAIN 1 trial, evaluating the efficacy and safety of semaglutide monotherapy vs placebo in 388 adults with type 2 diabetes,[1] showed that, from a mean baseline HbA1c of 8.1%, adults treated with 0.5 mg and 1.0 mg semaglutide achieved significantly greater HbA1c reductions of 1.5% and 1.6%, respectively, vs <0.1% with placebo.

In addition, more adults treated with 0.5 mg and 1.0 mg semaglutide achieved HbA1c targets compared with placebo: HbA1c <7% (74% and 72% vs 25%) and <=6.5% (59% and 60% vs 13%). The trial also demonstrated that adults treated with 0.5 mg and 1.0 mg semaglutide achieved significantly greater reductions from baseline in mean body weight of 3.7 kg/8.16 lb and 4.5 kg/9.92 lb, respectively, vs 1.0 kg/2.20 lb with placebo.[1]

"Achieving glycaemic control remains a significant challenge for people with type 2 diabetes and their treating physicians," said Christopher Sorli, SUSTAIN 1 investigator and Chair of the Department of Diabetes, Endocrinology and Metabolism, Billings Clinic, US. "It is encouraging that almost three out of four adults treated with semaglutide in the SUSTAIN 1 trial achieved the HbA1c target of less than seven percent."

Furthermore, adults treated with both doses of semaglutide demonstrated significantly greater reductions from baseline in fasting plasma glucose compared with placebo (2.5 mmol/L or 45.2 mg/dL and 2.3 mmol/L or 42.1 mg/dL, respectively, vs 0.6 mmol/L or 9.9 mg/dL).[1]

The most common adverse events observed for adults treated with 0.5 mg and 1.0 mg semaglutide and placebo were gastrointestinal, which were mainly mild or moderate (nausea: 20.3% and 23.8% vs 7.8%; vomiting: 3.9% and 6.9% vs 1.6%; diarrhoea: 12.5% and 10.8% vs 2.3%). The rate of nausea diminished over time. Comparable rates of severe adverse events were observed for adults treated with 0.5 mg and 1.0 mg semaglutide compared with placebo (5.5% and 5.4% vs 3.9%). The proportion of adults discontinuing due to adverse events was low across treatment groups (6.3% and 5.4% vs 2.3%).[1]

About semaglutide

Semaglutide is an analogue of native human glucagon-like peptide-1 (GLP-1) that stimulates insulin and suppresses glucagon secretion in a glucose-dependent manner, as well as decreases appetite and food intake.[2] Semaglutide administered subcutaneously once-weekly is in phase 3 development for the treatment of type 2 diabetes.


SUSTAIN 1 is a randomised, double-blind, placebo-controlled, multicentre, multinational 30-week trial investigating the safety and efficacy of semaglutide, administered once-weekly, versus placebo in 388 people with type 2 diabetes who had not received any blood glucose lowering therapies 90 days prior to trial participation. The trial was conducted in Canada, Italy, Japan, Mexico, Russia, South Africa, UK and the US.

About the SUSTAIN clinical programme

SUSTAIN (Semaglutide Unabated Sustainability in Treatment of Type 2 Diabetes) is a clinical programme for semaglutide, administered once-weekly, that comprises six phase 3a global clinical trials encompassing more than 7,000 people with type 2 diabetes as well as two Japanese trials encompassing around 1,000 people with type 2 diabetes.
