Saxenda® demonstrated significant improvements in cardiometabolic risk factors over three years compared with placebo

Novo NordiskToday, new data from the three-year part of the phase 3a SCALE™ (Satiety and Clinical Adiposity - Liraglutide Evidence) Obesity and Prediabetes trial were presented at the Endocrine Society's 98th Annual Meeting and Expo (ENDO 2016). The three-year part of the trial (n=2,254 adults with obesity or who were overweight with comorbidities and had prediabetes at baseline) data demonstrated that 160 weeks of treatment with Saxenda® (liraglutide 3 mg) (n=1,505) in combination with a reduced-calorie diet and increased physical activity resulted in significant improvements in cardiometabolic risk factors (such as blood pressure and cholesterol) compared with placebo (reduced-calorie diet and increased physical activity alone) (n=749).(1)

At week 160, individuals treated with Saxenda® had lost more weight (6.1%) than those treated with placebo (1.9%) (estimated treatment difference [ETD] -4.3% [95% CI -4.9; -3.7], p<0.0001).(1) In addition, treatment with Saxenda® achieved results beyond weight loss including improvements in some cardiometabolic risk factors such as blood pressure and cholesterol. At week 160, participants randomised to treatment with Saxenda® experienced a greater reduction in systolic blood pressure compared with placebo (ETD -2.8 mmHg [-3.8; -1.8], p<0.0001). Those treated with Saxenda® also experienced greater improvements in triglycerides (ETD -6% [-9; -3], p=0.0003) and total cholesterol levels (ETD -2% [-3; 0], p=0.03) compared with placebo. Additionally, people treated with Saxenda® showed a greater reduction in mean waist circumference compared with placebo (ETD -3.5 cm [-4.2; -2.8]).

"We know that weight loss of as little as 5 to 10% in people with obesity can have an impact on cardiometabolic risk factors," said Dr Ken Fujioka, Scripps Clinic, San Diego, California, US and a SCALE™ clinical trial investigator. "This is currently the longest weight-management trial with Saxenda®, and the observed improvements in blood pressure, lipids and waist circumference at three years are encouraging."

In addition, the three-year part of the SCALE™ Obesity and Prediabetes trial met its primary endpoint, demonstrating that continued treatment over three years with Saxenda®, in combination with a reduced-calorie diet and increased physical activity, delayed the onset of type 2 diabetes compared with placebo.(1)

Aligned with previous trials, during treatment with Saxenda®, mean pulse rate was increased (ETD +2 beats/min [+1.2; +2.7], p<0.0001). Saxenda® was generally well tolerated, and observed side effects were in line with previous trials.(2) Over 160 weeks, reports of serious adverse events were higher in those treated with Saxenda® compared with placebo (15.1% vs 12.9%). Rates of gallbladder-related adverse events and confirmed acute pancreatitis were low, but more frequent in those treated with Saxenda® (2.9 events per 100 patient-years of observation [PYO] and 0.29/100 PYO, respectively) vs placebo (1.2/100 PYO and 0.13/100 PYO, respectively). The frequency of adjudicated major adverse cardiovascular events was low, and comparable in those treated with Saxenda® and placebo (0.19 vs 0.20 events/100 PYO).(1)

About obesity
Obesity is a disease(3) that requires long-term management. It is associated with many serious health consequences and decreased life-expectancy.(4,5) Obesity-related comorbidities include type 2 diabetes, heart disease, obstructive sleep apnoea (OSA) and certain types of cancer.(4,6,7) It is a complex and multi-factorial disease that is influenced by genetic, physiological, environmental and psychological factors.(8)

The global increase in the prevalence of obesity is a public health issue that has severe cost implications to healthcare systems. In 2014, 13% of adults, or approximately 600 million adults, were living with obesity.(9)

About Saxenda®
Saxenda® (liraglutide 3 mg) is a once-daily glucagon-like peptide-1 (GLP-1) analogue with 97% similarity to naturally occurring human GLP-1, a hormone that is released in response to food intake.(10) Like human GLP-1, Saxenda® regulates appetite by increasing feelings of fullness and satiety, while lowering feelings of hunger and prospective food consumption, thereby leading to reduced food intake. As with other GLP-1 receptor agonists, Saxenda® stimulates insulin secretion and lowers glucagon secretion in a glucose-dependent manner.(2) Saxenda® was evaluated in the SCALE™ (Satiety and Clinical Adiposity - Liraglutide Evidence) phase 3 clinical trial programme.

Saxenda® is approved in the US as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with obesity (BMI of ≥30 kg/m2) or who are overweight (BMI of ≥27 kg/m2) in the presence of at least one weight-related comorbid condition (e.g. hypertension, dyslipidaemia, type 2 diabetes).(11)

In the EU, Saxenda® is indicated as an adjunct to a reduced-calorie diet and increased physical activity for weight management in adult patients with an initial BMI of ≥30 kg/m2 (obese), or ≥27 kg/m2 to <30 kg/m2 (overweight) in the presence of at least one weight-related comorbidity such as dysglycaemia (prediabetes or type 2 diabetes mellitus), hypertension, dyslipidaemia or obstructive sleep apnoea.(2)

Guidance is given in the label that treatment with Saxenda® should be discontinued if a specific threshold of weight loss has not been achieved after a certain period of time.

About the SCALE™ clinical development programme
Novo Nordisk's phase 3 development programme, called SCALE™, investigates liraglutide 3 mg for weight management. SCALE™ (Satiety and Clinical Adiposity - Liraglutide Evidence) consists of four, placebo-controlled, multinational trials called: SCALE™ Obesity and Prediabetes, SCALE™ Diabetes, SCALE™ Sleep Apnoea and SCALE™ Maintenance. The trials include more than 5,000 people who are overweight (BMI ≥27 kg/m2) with comorbidities such as hypertension, dyslipidaemia, obstructive sleep apnoea (OSA), or type 2 diabetes or who have obesity (BMI ≥30 kg/m2), with or without comorbidities. The studies all involved a reduced-calorie diet and increased physical activity.

Key results from all trials in the SCALE™ clinical development programme have been published, with further data expected to be presented and published throughout 2016.
