- Cardiovascular disease - the world's number one cause of death, killing 17 million people each year.(2) Hypertension is a major risk factor for cardiovascular disease.(3)
- Diabetes - nine of every 10 people with type 2 diabetes are overweight.(4) WHO projects that diabetes deaths will increase by more than 50% worldwide in the next 10 years(5)
"We know that the incidence of type 2 diabetes and hypertension rises steeply with increasing body weight," said Professor Iain Broom, Department of Clinical Biochemistry and Metabolic Medicine, Grampian University Hospitals NHS Trust, UK and study lead. "These results support the use of Xenical to achieve substantial weight loss, and to improve cardiovascular health and manage independent risk factors in overweight and obese people." The study analysis involved 2,692 overweight and obese people. Patients with high cardiovascular risk (type 2 diabetes and hypertension), and treated with Xenical vs. placebo demonstrated significant improvem ents in:
- Blood pressure (SBP: -6.45 mmHg vs. -3.47 mmHg, p(less than)0.01; DBP: -4.31 mmHg vs. -3.11 mmHg, p=NS). 15.3% of patients treated with Xenical returned to normal blood pressure vs. 8.7% receiving placebo (p(less than)0.05)
- Blood glucose levels - HbA1c (-0.41% vs. -0.03%, p(less than)0.0001)
- Insulin (-25.02 pmol/l vs. -14.17 pmol/l, p(less than)0.01)
- Fasting glucose (-1.23 mmol/l vs. -0.38mmol/l, p(less than)0.0001)
- Total cholesterol (-4.19% vs. 0.77%, p(less than)0.0001) and LDL cholesterol (-7.32% vs. 1.98%, p(less than)0.0001) >>
Xenical patients more than doubled their weight loss vs. placebo (-4.83kg vs. -1.49kg, p(less than)0.0001), which was also reflected in reduced waist circumference (-5.20cm vs. -1.98cm, p(less than)0.0001). In patients who responded early to treatment (greater than or equal to 5% weight loss at 3 months)(X), Xenical produced even greater changes in blood pressure (SBP/DBP: -13.16/-7.83 mmHg), HbA1c (-0.84%), insulin (-38.72 pmol/l), fasting glucose (-1.92 mmol/l) and weight (-9.61kg) vs. placebo. Blood pressure normalisation was more than two-fold greater with Xenical vs. placebo (24.2% vs. 10.5%). Data from two additional study analyses presented at ECO also confirm Xenical's role in reducing cardiovascular risk:
- Obese patients with hypertension who responded early to treatment with Xenical experienced greater reductions in weight, waist circumference and lipid levels vs. placebo. 48% of patients treated with Xenical returned to normal blood pressure levels vs. 40.2% of placebo patients(6).
- Xenical was also shown to improve risks associated with the metabolic syndrome (based on NCEP ATP III criteria). Of particular note was the large improvement in LDL cholesterol with Xenical vs. placebo after one year (-7.5% vs. 5.3%, p(less than)0.0001)(7) >>

About Xenical(R) (orlistat 120 mg)
Xenic al is the only available weight loss medication that works locally in the gut to prevent dietary fat absorption by around 30% to effectively promote weight loss. The efficacy and safety of Xenical has been proven in an extensive clinical trials programme, with over 100 Phase III/IV trials, in over 30,000 patients. Xenical is the most extensively studied weight loss medication in the world, and the only weight loss drug studied up to 4 years.(8) People can lose up to twice as much weight with Xenical compared to lifestyle changes alone.(9,10) Xenical also improves cardiovascular risk factors, reduces the risk of developing type 2 diabetes, and improves components of the metabolic syndrome.(8,11) XENDOS was the first study to show that treatment with a weight loss medication, Xenical, can significantly reduce the risk of developing type 2 diabetes.(8) Xenical is well tolerated and unlike appetite suppressants, it does not act on the brain. Xenical is suitable for use in a broad range of patients, including those with hypertension, dyslipidaemia, type 2 diabetes and multi-morbidities. Since Xenical was first marketed in 1998, there have been more than 28 million patient treatments world-wide. Xenical is licensed for use in 149 countries around the world.
About Xenical Weight Management Programmes
Roche has developed Xenical Weight Management Programmes (WMPs) for healthcare professionals to use with their patients. The programme aims to help patients set and reach realistic weight goals while modifying their dietary intake and behaviour in the long-term. The programmes are individually tailored to help people achieve their weight loss goals, and maintain weight loss, through healthy eating, physical activity, beh aviour modification and pharmacotherapy. Roche provides free patient support programmes in around 50 countries worldwide to help people taking Xenical. Recent data demonstrated that patients enrolled in Xenical WMPs can significantly improve the levels of weight loss achieved and can increase their overall satisfaction and compliance with treatment.
Headquartered in Basel, Switzerland, Roche is one of the world's leading research-focused healthcare groups in the fields of pharmaceuticals and diagnostics. As the world's biggest biotech company and an innovator of products and services for the early detection, prevention, diagnosis and treatment of diseases, the Group contributes on a broad range of fronts to improving people's health and quality of life. Roche is the world leader in diagnostics and drugs for cancer and transplantation, a market leader in virology and active in other major therapeutic areas such as autoimmune diseases, inflammation, metabolism and central nervous system. In 2006 sales by the Pharmaceuticals Division totalled 33.3 billion Swiss francs, and the Diagnostics Division posted sales of 8.7 billion Swiss francs. Roche employs roughly 75,000 worldwide and has R&D agreements and strategic alliances with numerous partners, including majority ownership interests in Genentech and Chugai.
