About this study

Official title: Diet With or Without Metarecod® in Obese Subjects With Type 2 Diabetes: Effect on Body Weight, in Vivo Oxidative Stress, Endothelial Function, Low-grade Inflammation and Gut Microbiota

Obesity is considered the largest chronic non-communicable disease (globesity) worldwide with a growing trend in the near future. Weight loss programs are strongly recommended in obese patients, especially with type 1 diabetes mellitus (T2DM), although the majority of subjects do not reach or maintain the recommended weight loss target with nutritional intervention alone and one-third of those who achieve a significant weight loss returns to original body weight within one year. Metarecod® (Neopolicaptil Gel Retard) is a substance based medical device consisting of a macromolecule complex derived from high-fiber raw materials, whose mode of action consists in creating an endoluminal gel in the gut that limits glucose and lipids absorption. The primary aim of the present study is to assess whether the combination of Metarecod® and standard diet as compared to diet alone can achieve a superior weight loss over 12 months of treatment. The present study will also compare the effects of the combination of Metarecod® and diet vs diet alone on:

  1. the improvement of glycemic variability and metabolic indexes;
  2. the oxidative status, the endothelial anti-thrombotic activity, the inflammatory status;
  3. the induction of favorable changes in gut microbiota composition and intestinal permeability.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MetarecodDietary supplement

    Policaptil Gel Retard: Metarecod®. The medical device will be given as 1 sachet twice daily

  • DietOther

    Diet program will be planned to achieve a ≥8% body weight relative reduction over 12 months and tailored calculating a 20% caloric relative decrease from habitual energy intake, corresponding to an average energy deficit of approximately 500 kcal/daily (approximately a total of 1,200-1,500/daily Kcal for women and 1,500-1,800/daily Kcal for men), with <30% of total calories from fat (<10% from satured fats) and at least 15% of total calories from proteins. For carbohydrate intake, low glycemic index food will be preferred to high glycemic index food, to prevent higher post prandial glycemic excursions

The record says: opening soon, as of the sponsor's last update on 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Dario Pitocco (+39 0630154071, dario.pitocco@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body Weight (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06813170, which also lists 18 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2025.
