Trial summary

Overweight and obesity have reached worldwide epidemic level. Both overweight and obesity are characterized by comorbidities such as cardio-metabolic risk factors (i.e., insulin resistance, type 2 diabetes, hypertension, dyslipidemia, low-grade inflammation) representing a major public health problem.

About this study

Official title: Evaluation of the Effects Associated With the Administration of Akkermansia Muciniphila on Parameters of Metabolic Syndrome Related to Obesity

Overweight and obesity have reached worldwide epidemic level. Both overweight and obesity are characterized by comorbidities such as cardio-metabolic risk factors (i.e., insulin resistance, type 2 diabetes, hypertension, dyslipidemia, low-grade inflammation) representing a major public health problem. Therefore, it is urgent to find a therapeutic solution to target all these metabolic disorders. Among the environmental factors able to influence the individual susceptibility to gain weight and to develop metabolic disorders associated with obesity, more and more evidence show that the trillions of bacteria housed in our gastro-intestinal tract (i.e, gut microbiota) influence host metabolism. The investigators recently discovered a putative interesting microbial candidate, namely Akkermansia muciniphila (Akk). More exactly, we found that the administration of Akkermansia muciniphila reduced body weight gain, fat mass gain, glycemia and inflammatory markers in diet-induced obese mice. Moreover, in overweight/obese patients with cardiovascular risk factors subjected to a calorie restriction diet (calorie restriction diet for 6 weeks and an additional 6 weeks of weight maintenance), a higher abundance of Akkermansia muciniphila was associated with a better cardio-metabolic status in these patients. The investigators also discovered that patients having more Akkermansia muciniphila in their gut before the calorie restriction exhibited a greater improvement in glucose homoeostasis, blood lipids and body composition after calorie restriction. These observations suggested that the administration of Akkermansia muciniphila in overweight or obese people could be a very interesting therapeutic solution. Currently, no human study has investigated the beneficial effects of Akkermansia muciniphila administration on obesity and metabolic disorders. The overall objective of this study is to evaluate the effects associated with the administration of live or heat-killed Akkermansia muciniphila on the metabolic disorders (insulin-resistance, type-2 diabetes, dyslipidemia, inflammation) related to overweight and obesity in humans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Tolerance (time frame: 15 days). The study lists 19 primary outcomes in all. 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 NCT02637115, which also lists 5 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 17 May 2019.
