A Study to Evaluate the Effect of BTI320 (SUGARDOWN®) on Post-Prandial Hyperglycaemia in High Risk Chinese Subjects With Pre-Diabetes
In Brief
A Phase 2 clinical trial evaluating BTI320 and BTI320 matching placebo for Pre-Diabetes. Completed, enrolled 60 participants across 1 site.
Detailed Summary
This is a single-centre, 16-week, randomized, double-blind, placebo-controlled, 3-treatment arm pilot study to evaluate the efficacy and safety of BTI320 in the treatment of high risk subjects with pre-diabetes. This is a pilot study aiming to test whether taking a medicine named BTI320 that slows down carbohydrate absorption in the gut, will lower blood sugar. The study aims to recruit 60 individuals in Hong Kong. To take part in the study, subjects must have pre-diabetes, that is, they have blood sugar levels that are above normal but not reaching diabetes range. The medicine BTI320 is currently licensed as a health supplement in Hong Kong and is known alternatively as SUGARDOWN®. The investigators are comparing the effectiveness of BTI320 against a dummy tablet. Both tablets look and taste identical and during the study, subjects will not know which of these tablets they are taking. There is a 4 in 5 chance of receiving active medication and 1 in 5 chance of receiving placebo. Subjects will be followed up closely every 2 to 4 weeks for a period of time up to 22 weeks. The study visits will take between 30 minutes to 3 hours, depending on additional checks that are required on a particular visit including oral glucose tolerance test and meal tolerance test. At visits involving meal tolerance test, subjects will be required to stay for approximately 3 hours. In addition, at Visit 2, Visit 4 and 3 days before Visit 7, a continuous glucose monitoring system device will be installed. Throughout the study period, subjects will return to the study center for check-ups including careful enquiry about whether they have developed any side-effects from taking the medication, physical examination, as well as blood tests.

Timeline
Interventions
BTI320, also known as SUGARDOWN®, is derived from galactomanan which blocks key enzymes that break down carbohydrate in the gut. BTI320 therefore helps to slow down the absorption of carbohydrates to lower post-meal blood sugar.
