The weight loss medication Xenical helps patients achieve rapid and sustained weight loss according to the results of a new study designed to reflect real world usage of Xenical in clinical practice. 1

The 12 month study of 430 overweight men and women (BMI of 30-43 kg/m2), was designed to assess the effectiveness of Xenical in patients who are responsive to treatment. Patients who achieved 5 per cent (approximately 5kg) weight loss after 3 months and maintained this after a further 3 months of Xenical treatment, were followed for one year. During this time weight loss and other health improvements, such as reductions in blood pressure, were assessed. The results suggest that the efficacy of Xenical in a real-life clinical practice setting is even greater than that demonstrated previously in clinical trials:

  • The greatest weight loss was seen in the first four weeks of treatment, with an average weight loss of 4.1 kg
  • Three out of four people achieved 5 per cent weight loss by month three, losing an average of 8kg
  • By month 6, 92 per cent of these people had maintained at least 5 per cent weight loss, with an average weight loss of 10.9kg.
  • The average weight loss after one year was 11.6 kg. One in two patients in the study lost more than 10 per cent of their initial weight, and over 8 in ten people lost more than 5 per cent — an amount of weight loss shown to clinically improve the health and well-being of overweight people 2

Commenting on the results, lead study investigator Professor Hermann Toplak from the Karl-Franzens-Universität, Graz, Austria said “These results demonstrate the significant benefits of rapid and continuous weight loss with Xenical in a clinical practice setting. Patients who respond rapidly to treatment continue with treatment and achieve long-term success.”

Results also demonstrated significant health gains associated with weight loss with Xenical. Specifically, people treated with Xenical achieved improvements in:

  • Waist circumference: An average reduction of 10.8 cm was achieved after one year. Excess fat around the waist is associated with insulin resistance, high blood sugar, high cholesterol levels and high blood pressure
  • Blood pressure (bp): In patients with hypertension, mean systolic and diastolic blood pressure were reduced by 18.1mmHg and 9.9mmHg respectively
  • Cholesterol: The lipid profile of patients was markedly improved: mean LDL-cholesterol (‘bad’ cholesterol) levels were reduced by 10.7 per cent and mean total cholesterol levels by 6.8 per cent

The reductions in blood pressure are a key finding as the number of overweight people with hypertension is almost three times higher than the number of adults with a healthy weight. 3 Xenical is the only prescription weight-loss medication, which can be used in patients with hypertension or uncontrolled hypertension.4

Xenical’s mode of action is unique. Unlike appetite suppressants, which have a history of withdrawals because of safety concerns, Xenical does not act on the central nervous system. As a result of Xenical’s non-systemic mode of action, it has a safety and tolerability profile, which makes it appropriate for use in a wide range of people. This is particularly important within the area of overweight / obesity, where a significant number of people suffer from, or are at risk of cardiovascular disease.

Notes to Editors:
Xenical is the only available weight loss medication that works locally in the gut to prevent dietary fat absorption by around 30 per cent and effectively promotes weight loss. It is an effective therapy that not only helps patients lose weight, but also helps them maintain their weight loss. Xenical is well tolerated and unlike appetite suppressants, it does not act on the brain. In clinical trials people taking Xenical in conjunction with a mildly reduced calorie diet have shown twice as much weight loss as diet alone. Since it was first marketed in 1998, there have been more than 11.5 million patient treatments with Xenical world-wide. Xenical is licensed for weight management in 149 countries around the world.

About Xenical Weight Management Programmes
Roche has developed the Xenical weight management programme (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, behaviour modification and pharmacotherapy.

Roche provides free patient support programmes in around 50 countries worldwide to help support 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.7
