Medical device treating obesity

St. Paul, Minnesota – EnteroMedics Inc. officials announce that the U.S. Food and Drug Administration (FDA) has approved VBLOC vagal blocking therapy, delivered via the Maestro System. Approval is for the treatment of adult patients with obesity who have a Body Mass Index (BMI) of at least 40kg/m² to 45kg/m², or a BMI of at least 35kg/m² to 39.9kg/m² with a related health condition such as high blood pressure or high cholesterol levels, and who have tried to lose weight in a supervised weight management program within the past 5 years. The Maestro System is the first new medical device to be approved by the FDA for obesity in more than 10 years. EnteroMedics anticipates that the device will be available, on a limited basis, at select Bariatric Centers of Excellence in the U.S. this year. The Maestro System has received CE Mark and is listed on the Australian Register of Therapeutic Goods.

“VBLOC Therapy offers an entirely new approach to the treatment of obesity,” said Scott Shikora, MD, FACS, EnteroMedics’ chief consulting medical officer. “By blocking signals along the nerves that connect the brain and stomach, VBLOC to reduces feelings of hunger and promotes earlier feelings of fullness, which can help people with obesity reduce the number of calories consumed and promote safe, healthy and durable weight loss.”

The Maestro System is a pacemaker–like device that is implanted, usually in an outpatient procedure, to control both hunger and fullness by intermittently blocking the primary nerve which regulates the digestive system, the vagus nerve. VBLOC Therapy does not surgically alter or restrict the digestive system, does not create barriers to prevent absorption of nutrients and is completely reversible, allowing patients to lose weight without lifestyle compromises.

“Obesity is a global epidemic with far-reaching cost and consequences to both public and personal health,” said Caroline M. Apovian, MD, FACP, FACN, professor of medicine at Boston University School of Medicine, and Director, Nutrition and Weight Management at Boston Medical Center. “From diet and exercise to bypass surgery, existing treatment options have failed to stop the advance of this disease. The Maestro System adds a safe and effective new weapon to our armamentarium, offering the patient a treatment option that does not physically restrict or alter the anatomy, and is reversible.”

“The Obesity Action Coalition applauds the FDA and EnteroMedics for making available the first device for the treatment of obesity in more than a decade. There is no ‘one–size–fits–all’ approach to treating the disease of obesity. We believe strongly that expanded treatment options are essential to individuals affected by obesity, so that along with their healthcare provider, they can make an informed decision on which option, or options, may work best to improve their health,” said Joe Nadglowski, Obesity Action Coalition president and CEO.

“FDA approval of VBLOC Therapy is a transformational event for not only EnteroMedics and the many supporters who have helped us achieve this milestone but, more importantly, for the people with the diseases of obesity that have been waiting for a new option,” said Mark B. Knudson, Ph.D., EnteroMedics' president and CEO. “The Maestro System fills a significant gap in the currently available treatment options, offering clinically meaningful weight loss without the fear or many of the side effects associated with existing bariatric options. We thank the many patients, and their families, who have participated in the clinical trials of VBLOC Therapy. We are also grateful to the physicians and healthcare providers who have worked with us on these clinical trials, our dedicated employees, as well as to the FDA for their efforts in making this technology available.”
