Clinical Trial Summary

This is a mechanistic, single-center, double-blind, placebo- and active-controlled, three-time-period, crossover study to evaluate the effect of sprinkled format REDUCOSE compared to placebo (double-blind; confirmative) and active control (open-label; acarbose - explorative) on post prandial glycemia in Asian patients with type 2 diabetes.

• Ongoing or recent (i.e. < 3 month) injectable insulin therapy.
• Ongoing or recent (i.e. < 3 month) weight loss interventions (e.g. dietary weight loss programs) or any history of bariatric surgery or any documented weight loss >5% within previous 6 months.
• Ongoing or recent (i.e. < 3 month) treatment with anorectic drugs, systemic steroids, medications known to affect gastric motility, or any condition known to affect gastro-intestinal integrity and food absorption.
• Major medical/surgical event requiring hospitalization in the last 3 months.
• Known allergy and intolerance to product components or paracetamol.
• Alcohol intake higher than 2 servings per day. A serving is 0.4 dl of strong alcohols, 1 dl of red or white wine, or 3 dl of beer.
• Are unable to comply with protocol procedures in the opinion of the investigator.
• Have a hierarchical link with the research team members.
• Positive pregnancy test or breast-feeding at screening.
• Participants who have been dosed in another clinical study with any investigational drug/new chemical entity within 30 days or 5 half-lives (whichever is longer) prior to screening.
• Donation of blood or significant amount of blood loss within 8 weeks prior to screening. Participants must also agree to not donate blood within 8 weeks after their last visit.
