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

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.

About this study

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.

Secondary outcomes

  1. Proportion body weight

    Time frame: 12 weeks

    To assess the efficacy of Glucosanol™ to increase the proportions of subjects who lose at least 3% and 5% of baseline body weight

  2. waist circumference

    Time frame: 12 weeks

    Changes in waist circumference

  3. hip circumference

    Time frame: 12 weeks

    Changes in hip circumference

  4. waist-hip-ratio

    Time frame: 12 weeks

    Changes in waist-hip-ratio

  5. BMI

    Time frame: 12 weeks

    Changes in BMI

  6. body fat

    Time frame: 12 weeks

    Changes in body fat (% and kg) and fat free mass (kg)

  7. hunger

    Time frame: 12 weeks

    Changes in hunger, eating, and food craving-related items from a Control of Eating Questionnaire

  8. Global evaluation of feeling of satiety

    Time frame: 12 weeks

    This parameter will be assessed by a 4 points categorical scale

  9. Global evaluation of the efficacy

    Time frame: 12 weeks

    This parameter will be assessed by a 4 points categorical scale

  10. Global evaluation of safety

    Time frame: 12 weeks
