NCT05114018

Brief Summary

The purpose of this study is to demonstrate the efficacy of pasteurized Akkermansia muciniphila (pAKK) in improving insulin sensitivity in hyperglycaemic, but otherwise healthy persons with metabolic syndrome. This is the primary objective of this study. Secondary objectives consist of evaluation of the effects of next generation beneficial microbes on metabolic health, anthropometry and body composition, and safety. Therefore, the trial is designed as a phase 2, randomized, double-blind, placebo-controlled, parallel group, multi-center trial comparing pAKK with placebo in restoring insulin sensitivity in dysglycaemic but otherwise healthy subjects with metabolic syndrome. In total, 144 enrolled participants will attend 6 study visits in total. Study visits may be conducted in the clinic, at home by a Healthcare Professional, or by telephone / telemedicine.

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Written informed consent;
  • BMI between \>25 and \<40 Kg/m2;
  • Qualifying for the diagnosis of metabolic syndrome according to the International Diabetes Federation (IDF 2006) criteria. At least any three of five citeria, with the modification that the criterion FPG≥100 mg/dL (5.6 mmol/L) is required among at least three of five:
  • Increased waist circumference: for Europid, sub-Saharan African, Eastern and Middle-Eastern ≥94 cm (men) or ≥80 cm (women), with ethnic-specific waist circumference cut-points: for South Asian and Chinese patients, waist ≥90 cm (men) or ≥80 cm (women); for Japanese patients, waist ≥90 cm (men) or ≥80 cm (women);
  • Triglycerides ≥150 mg/dL (1.7 mmol/L) (exception: triglycerides ≥100 mg/dL (1.13mmol/L) for sub-Saharan African) or treatment for elevated triglycerides;
  • HDL cholesterol \<40 mg/dL (1.03 mmol/L) in men or \<50 mg/dL (1.29 mmol/L) in females, or treatment for low HDL;
  • Systolic blood pressure ≥130, diastolic blood pressure ≥85 mmHg, or treatment for hypertension;
  • FPG ≥100 mg/dL (5.6 mmol/L) or previously diagnosed type 2 diabetes; an oral glucose tolerance test is recommended for patients with an elevated FPG, but it is not required.
  • If participant has a prior diagnosis of pre-diabetes or Type II diabetes, and has been unmedicated for 3-months prior to screening;
  • If female, must meet all the following criteria:
  • Not pregnant or breastfeeding
  • If of childbearing potential (including peri-menopausal women who have had a menstrual period within one year) must practice and be willing to continue to practice appropriate birth control (defined as a method which results in a low failure rate, i.e., less than 1% per year, when used consistently and correctly, such as double barrier methods \[male condom with spermicide, with or without cervical cap or diaphragm\], implants, injectable or oral contraceptives \[must have been using for at least the last 3 months\], some intrauterine contraceptive devices, tubal ligation, or in an established relationship with a vasectomized partner) during the entire duration of the study
  • Be willing to maintain stable dietary habits and physical activity levels throughout the trial period;
  • Be able to communicate well with the Investigator, to understand and comply with the requirements of the study and be judged suitable for the study in the opinion of the Investigator.

  • Smoking more than 10 cigarettes per day;
  • Previous bariatric surgery;

  • Consumption of dietary supplements (omega-3 fatty acids, probiotics, prebiotics, plant stanols/sterols) in the 4-weeks before the study;
  • Presence or history of significant and diagnosed gastrointestinal diseases that, in the opinion of the investigator, could be associated with disturbed gastrointestinal absorption (e.g., resections, diverticula, active and diagnostically confirmed irritable bowel syndrome, malabsorption syndrome);
  • Present or recent (within 3-months of screening) use of any other medication which, in the opinion of the investigator, could interfere with the outcome of the study, including but not limited to antithrombotic agents, anti-inflammatory agents and chronic NSAID use (except low-dose prophylactic, proton pump inhibitors (PPIs), antihistamines, if ongoing (3-months) and on a stable dose throughout study period);
