LAVAL, QC, March 26, 2018 /CNW/ - Valeant Canada today announced that Health Canada has approved CONTRAVE® extended-release tablets for use as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults. Patients with an initial body mass index (BMI) of 30 kg/m2 or greater (obese) or 27 kg/m2 or greater (overweight) in the presence of at least one weight-related comorbidity (e.g., hypertension, type 2 diabetes mellitus or dyslipidemia) would be appropriate patients to take CONTRAVE®.1
"The approval of CONTRAVE® in Canada represents an important new option for physicians treating obesity," says Richard Lajoie, President, Valeant Canada. "We are extremely proud to bring this new innovative treatment for Canadian patients struggling to lose weight for the improvement of their health and quality of life. Obesity is a growing problem for patients and the Canadian economy with approximately 40 per cent of Canadian adults overweight or obese,2,3 and an economic burden ranging from $4.6 billion to $7.1 billion annually."4
Across four Phase III studies, CONTRAVE® patients with a BMI over 27 and a weight-related comorbidity, and patients affected by obesity (BMI over 30) lost up to four times more weight over one year by adding CONTRAVE® than with diet and exercise alone. In addition, over 60 per cent of patients taking CONTRAVE® lost five per cent or more body weight and kept it off for 56 weeks versus 23 per cent of patients taking a placebo.5,6,7,8
"Obesity is a widely prevalent, chronic and complex disease with associated health risks that can lower a person's life expectancy and quality of life," says Dr. Arya M. Sharma, founder and Scientific Director of the Canadian Obesity Network. "Therefore, the approval of CONTRAVE® benefits Canadians struggling and seeking help with their weight. I am excited to provide my patients with a new and clinically proven anti-obesity treatment option to help them take control of their weight and improve their health and well-being."
CONTRAVE® has been approved by the US Food and Drug Administration (FDA) in the United States since September 2014. Canada is the 25th country to launch CONTRAVE® worldwide. Valeant Canada licenses CONTRAVE® from Orexigen Therapeutics, Inc.
About Obesity in Canada
Approximately, 40 per cent of Canadian adults are overweight or obese.9,10 One in four, or about six million Canadian adults, are obese – meaning there are more Canadians living with obesity than those with diabetes, heart disease, arthritis, chronic lung disease or cancer.11
According the Canadian Obesity Network, Obesity is considered a chronic disease because managing weight is a lifelong process. This is because your body tries to 'defend' its fat stores to maintain your highest weight (this what researchers call 'starvation response').12 Obesity can lower a person's quality of life and shorten life expectancy. It can also lead to other associated illnesses.13,14,15 In fact, obesity is a leading cause of type 2 diabetes, high blood pressure, heart disease, stroke, osteoarthritis, affective disorders such as depression and cancer.16
Chronic weight management can result in improvements in weight-related illnesses and quality of life.17,18,19,20 Once a person has achieved a stable weight, even a modest sustained weight loss of five to 10 per cent of their total body weight can lead to additional health benefits, including improvements in blood glucose, blood pressure, cholesterol levels, arthritis, reflux disease, sleep apnea or fertility.21
About CONTRAVE® Clinical Trials Program22,23,24,25
Four 56-week multi-centre, double-blind, placebo-controlled obesity trials (CONTRAVE Obesity Research, or COR-I, COR-II, COR-BMOD, and COR-Diabetes) were conducted to evaluate the effect of CONTRAVE® in conjunction with lifestyle modification in 4,536 patients randomized to CONTRAVE® or placebo. The COR-I, COR-II, and COR-BMOD trials enrolled patients with obesity (BMI 30 kg/m2 or greater) or overweight (BMI 27 kg/m2 or greater) and at least one comorbidity (hypertension or dyslipidemia). The COR-Diabetes trial enrolled patients with BMI greater than 27 kg/m2 with type 2 diabetes with or without hypertension and/or dyslipidemia.
COR I and COR II included a program consisting of a reduced-calorie diet resulting in an approximate 500 kcal/day decrease in caloric intake, behavioral counseling, and increased physical activity. COR-BMOD included an intensive behavioral modification program consisting of 28 group counseling sessions over 56 weeks as well as a prescribed diet and exercise regimen. COR-Diabetes evaluated patients with type 2 diabetes not achieving glycemic goal of a HbA1c less than 7 per cent either with oral antidiabetic agents or with diet and exercise alone. Co-primary efficacy endpoints were percent change from baseline in body weight and proportion of participants who achieved a decrease in body weight of 5 per cent or more.
In these studies, the most common adverse reactions (≥5 percent) seen in patients taking CONTRAVE® included nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth and diarrhea.
