Study summary

The polyglucosamine, specification L112, is a medical device and in this clinical trial used for weight reduction in moderately obese participants following a long term treatment lasting 12 months. The rationale for this study is to show that overweight can be reduced by taking 2 times daily 2 tablets with the main meals.

Read the detailed description

Two groups of subjects were compared. A comparable diet condition, consisting of 10 % reduction of caloric intake was followed, according to a questionnaire based on the weekly number of servings. No modification of physical activity was requested.

One group had to take the polyglucosamine tablets and the other group placebo tablets for at least 12 months. It is known, that polyglucosamine is a fat binder acting in a physical-chemical manner, the positive charged fiber is bound to the negative charged dietary fat and this complex is unable to pass the gut wall into the body but is naturally excreted,hence this energy is not available. Therefore, this medical device should show a measurable reduction in body weight.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2014 to primary completion in Oct 2016, 29 months.

Of 98 industry-sponsored interventional studies with no phase under Obesity, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 29. This study's 29 months is above that.

Counting every sponsor, half of 2,351 studies reached it within 26 months; a quarter within 11 and three quarters within 48.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 25, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
