Last verified: July 2012
To date, there is no clinical evidence on the efficacy and safety of Glucosanol in maintaining weight loss beyond the study duration of 12 weeks. The rationale for this open-label study is to assess the efficacy in preventing regain of loss body weight and safety of Glucosanol in subjects who are overweight or obese over a longer period after the initial weight loss.

Condition Intervention Phase
Device: Glucosanol
Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Open-label Clinical Investigation to Evaluate the Safety and Efficacy of Glucosanol in Maintaining Body Weight Loss in Overweight and Obese Subjects
