Data presented at ObesityWeek showed Saxenda® (liraglutide [rDNA origin] injection) treatment demonstrated significant and sustained weight loss over three years compared with placebo

LOS ANGELES, Nov. 4, 2015 /PRNewswire/ -- Today, new data from the phase 3a SCALE™ (Satiety and Clinical Adiposity: Liraglutide Evidence in Non-Diabetic and Diabetic adults) Obesity and Pre-diabetes three-year trial extension were presented at ObesityWeek 2015, the 3^rd annual combined congress of the American Society for Metabolic and Bariatric Surgery and The Obesity Society. The extension part of the trial (n=2,254 adults with obesity or who were overweight with comorbidities and had pre-diabetes at baseline), demonstrated that treatment with Saxenda^® in combination with a reduced-calorie diet and increased physical activity resulted in significant and sustained weight loss over the three-year span, compared with placebo (reduced-calorie diet and increased physical activity alone).¹

At week 160, those randomized to treatment with Saxenda^® (n=1,505) achieved an average body weight loss of 6.1% from baseline, compared with 1.9% for placebo treatment (n=749; P<0.0001); 49.6% of adults treated with Saxenda^® achieved ≥5% weight loss, compared to 23.7% of adults on placebo (P<0.0001).^1,2 In addition, 24.8% lost more than 10% of their body weight when treated with Saxenda^® compared to 9.9% with placebo (P<0.0001). Moreover, 52.6% of adults who were treated with Saxenda^® completed the 160-week extension trial vs. 45% of those in the placebo group.¹

In addition, the extension met its primary end point, demonstrating that ongoing treatment with Saxenda^® in combination with reduced-calorie diet and increased physical activity delayed the onset of type 2 diabetes, compared with placebo.¹

"Losing and maintaining weight loss can be very challenging for adults with obesity or who are overweight," said Professor Carel le Roux, University College Dublin, Ireland, and SCALE^™ clinical trial investigator. "These data are very important as they demonstrated the clinical value of Saxenda^® over a period of three years."

Withdrawal rates due to adverse events were 13.3% with Saxenda^® (liraglutide [rDNA origin] injection) compared with 6.2% with placebo. Serious adverse events were reported by 15.1% in the Saxenda^® group and 12.9% with placebo. The incidence of gallbladder-related and confirmed pancreatitis events were more frequent 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).¹

Important Safety Information

What is the most important information I should know about Saxenda^®?

Serious side effects may happen in people who take Saxenda^®, including:

1.    Possible thyroid tumors, including cancer. During the drug testing process, the medicine in Saxenda^® caused rats and mice to develop tumors of the thyroid gland. Some of these tumors were cancers. It is not known if Saxenda^® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid cancer in people. If medullary thyroid cancer occurs, it may lead to death if not detected and treated early. If you develop tumors or cancer of the thyroid, your thyroid may have to be surgically removed.

• Before you start taking Saxenda^® (liraglutide [rDNA origin] injection), tell your health care professional if you or any of your family members have had thyroid cancer, especially medullary thyroid cancer, or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Do not take Saxenda^® if you or any of your family members have medullary thyroid cancer, or if you have MEN 2. People with these conditions already have a higher chance of developing medullary thyroid cancer in general and should not take Saxenda^®
• While taking Saxenda^®, tell your health care professional if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer

2.    Inflammation of the pancreas (pancreatitis), which may be severe and lead to death.

• Before taking Saxenda^®, tell your health care professional if you have had: pancreatitis, stones in your gallbladder (gallstones), a history of alcoholism, or high blood triglyceride levels. These medical conditions can make you more likely to get pancreatitis in general. It is not known if having these conditions will lead to a higher chance of getting pancreatitis while taking Saxenda^®
• While taking Saxenda^®: Stop taking Saxenda^® and call your health care professional right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may happen with or without vomiting. The pain may be felt going from your abdomen through to your back. This type of pain may be a symptom of pancreatitis

Who should not use Saxenda^®?

Do not use Saxenda^® if:

• you or any of your family members have a history of medullary thyroid cancer
• you have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). This is a disease where people have tumors in more than one gland in their body
• you are allergic to liraglutide or any of the ingredients in Saxenda^®. Symptoms of a serious allergic reaction may include: swelling of your face, lips, tongue, or throat, fainting or feeling dizzy, very rapid heartbeat, problems breathing or swallowing, and severe rash or itching. Talk with your health care professional if you are not sure if you have any of these conditions
• are pregnant or planning to become pregnant. Saxenda^® may harm your unborn baby

What should I tell my health care professional before using Saxenda^®?

Before taking Saxenda^®, tell your health care professional if you:

• have any of the conditions listed in the section "What is the most important information I should know about Saxenda^®?"
• are taking certain medications called GLP-1 receptor agonists
• are allergic to liraglutide or any of the other ingredients in Saxenda^®
• have severe problems with your stomach, such as slowed emptying of your stomach (gastroparesis) or problems with digesting food
• have or have had kidney or liver problems
• have or have had depression or suicidal thoughts
• have any other medical conditions
• are pregnant or plan to become pregnant. Saxenda^® (liraglutide [rDNA origin] injection) may harm your unborn baby. Tell your health care professional if you become pregnant while taking Saxenda^®. If you are pregnant you should stop using Saxenda^®
• are breastfeeding or plan to breastfeed. It is not known if Saxenda^® passes into your breast milk. You and your health care professional should decide if you will take Saxenda^® or breastfeed. You should not do both without talking with your health care professional first

Tell your health care professional about all the medicines you take including prescription and nonprescription medicines, vitamins, and herbal supplements. Saxenda^® slows stomach emptying and can affect medicines that need to pass through the stomach quickly. Saxenda^® may affect the way some medicines work and some other medicines may affect the way Saxenda^® works. Tell your health care professional if you take diabetes medicines, especially sulfonylurea medicines or insulin.

Know the medicines you take. Keep a list of them with you to show your health care professional and pharmacist each time you get a new medicine.

How should I use Saxenda^®?

• Inject your dose of Saxenda^® under the skin (subcutaneous injection) in your stomach area (abdomen), upper leg (thigh), or upper arm, as instructed by your health care professional. Do not inject into a vein or muscle
• Never share your Saxenda^® pen or needles with another person. You may give an infection to them, or get an infection from them

What are the possible side effects of Saxenda^®?

Saxenda^® may cause serious side effects, including:

• possible thyroid tumors, including cancer
• inflammation of the pancreas (pancreatitis)
• gallbladder problems. Saxenda^® may cause gallbladder problems including gallstones. Some gallbladder problems need surgery. Call your health care professional if you have any of the following symptoms: pain in your upper stomach (abdomen), fever, yellowing of your skin or eyes (jaundice), and clay-colored stools
• low blood sugar (hypoglycemia) in people with type 2 diabetes who also take medicines to treat type 2 diabetes. Saxenda^® can cause low blood sugar in people with type 2 diabetes who also take medicines used to treat type 2 diabetes (such as sulfonylureas). In some people, the blood sugar may get so low that they need another person to help them. If you take a sulfonylurea medicine, low blood sugar may include: shakiness, sweating, headache, drowsiness, weakness, confusion, irritability, hunger, fast heartbeat, feeling jittery, and dizziness. You should check your blood sugar before you start taking Saxenda^® (liraglutide [rDNA origin] injection) and while you take Saxenda^®
• increased heart rate. Saxenda^® can increase your heart rate while you are at rest. Your health care professional should check your heart rate while you take Saxenda^®. Tell your health care professional if you feel your heart racing or pounding in your chest and it lasts for several minutes when taking Saxenda^®
• kidney problems (kidney failure). Saxenda^® may cause nausea, vomiting, or diarrhea leading to loss of fluids (dehydration). Dehydration may cause kidney failure, which can lead to the need for dialysis. This can happen in people who have never had kidney problems before. Drinking plenty of fluids may reduce your chance of dehydration. Call your health care professional right away if you have nausea, vomiting, or diarrhea that does not go away, or if you cannot drink liquids by mouth
• serious allergic reactions. Serious allergic reactions can happen with Saxenda^®. Stop using Saxenda^®, and get medical help right away if you have any symptoms of a serious allergic reaction
• depression or thoughts of suicide. You should pay attention to any mental changes, especially sudden changes, in your mood, behaviors, thoughts, or feelings. Call your health care professional right away if you have any mental changes that are new, worse, or worry you

Common side effects of Saxenda^® include nausea, diarrhea, constipation, low blood sugar (hypoglycemia), vomiting, headache, decreased appetite, upset stomach, tiredness, dizziness, stomach pain, and changes in enzyme (lipase) levels in your blood. Nausea is most common when first starting Saxenda^®, but decreases over time in most people as their body gets used to the medicine. Tell your health care professional if you have any side effect that bothers you or that does not go away.

About obesity   
The global increase in the prevalence of obesity is a public health issue that has severe cost implications to health care systems.^3,4 In 2011–2012 in the US, approximately 35% of adults, or nearly 79 million adults, live with obesity.^5,6  

About Saxenda^®
Saxenda^® is a once-daily glucagon-like peptide-1 (GLP-1) receptor agonist with 97% similarity to naturally occurring human GLP-1, a hormone that is released in response to food intake. Like human GLP-1, Saxenda^® regulates appetite and lowers body weight through decreased food intake. As with other GLP-1 receptor agonists, liraglutide stimulates insulin secretion and reduces glucagon secretion in a glucose-dependent manner. These effects can lead to a reduction of blood glucose. Saxenda^® was evaluated in the SCALE™ (Satiety and Clinical Adiposity−Liraglutide Evidence in Non-diabetic and Diabetic adults) phase 3 clinical trial program.⁷

Saxenda^® was approved by the FDA on December 23, 2014, 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, dyslipidemia, type 2 diabetes).^2,7

Saxenda^® (liraglutide [rDNA origin] injection) was approved by Health Canada on February 26, 2015, and was granted European marketing authorization on March 23, 2015, by the European Commission (EC). It was also approved in Mexico on September 30, 2015.² Please refer to the local labels for more information.  

Guidance is given in all labels 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 SCALE™ Obesity and Pre-diabetes
The SCALE™ Obesity and Pre-diabetes trial is a randomized, double-blind, placebo-controlled, multinational trial in adults without diabetes with obesity and adults without diabetes who are overweight with weight-related comorbidities. There were 3,731 participants randomized to treatment with Saxenda^® or placebo in combination with reduced-calorie diet and increased physical activity.⁷ In addition, participants were further stratified to 56 weeks or 160 weeks of treatment based on pre-diabetes status at baseline screening.²

The objectives of this trial were to demonstrate the safety and efficacy of Saxenda^® compared with placebo, as well as to investigate the long-term potential efficacy of Saxenda^® to delay the onset of type 2 diabetes in participants with pre-diabetes at baseline screening.²

It is the largest of the phase 3a trials in the SCALE™ clinical development program, which encompassed more than 5,000 adults with obesity or adults who are overweight with weight-related comorbidities.²
