Safety and Efficacy of Glucosanol in Reducing Body Weight in Overweight and Obese Subjects

• Proportion body weight [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  To assess the efficacy of Glucosanol™ to increase the proportions of subjects who lose at least 3% and 5% of baseline body weight
• waist circumference [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in waist circumference
• hip circumference [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in hip circumference
• waist-hip-ratio [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in waist-hip-ratio
• BMI [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in BMI
• body fat [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in body fat (% and kg) and fat free mass (kg)
• hunger [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Changes in hunger, eating, and food craving-related items from a Control of Eating Questionnaire
• Global evaluation of feeling of satiety [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  This parameter will be assessed by a 4 points categorical scale
• Global evaluation of the efficacy [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  This parameter will be assessed by a 4 points categorical scale
• Global evaluation of safety [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  This will be assessed by both investigators and subjects by a 4 points categorical scale.

Glucosanol™, the medical device to be investigated contains a proprietary plant extract that is a natural inhibitor of alpha-amylase and can reduce starch digestion.

The rationale for this study is to confirm that Glucosanol™ ingestion will reduce body weight. A double-blind, randomized, placebo-controlled design has been chosen to assess the efficacy and safety of Glucosanol™ in subjects who are overweight and mildly obese.

Preparations that reduce absorption of calories from dietary carbohydrates could be decisively meaningful for the regulation of bodyweight or obesity. Hence, Glucosanol™ may be used as a tool for the treatment of obesity and weight management through reduced carbohydrate absorption.

The rationale for this study is to confirm that Glucosanol™ ingestion will reduce body weight. A double-blind, randomized, placebo-controlled design has been chosen to assess the efficacy and safety of Glucosanol™ in subjects who are overweight and mildly obese.

The specific hypotheses to be accepted or rejected by statistical data from the clinical investigation are beneficial effects of the device on weight loss (kg) and body fat content.
