About this study

The investigators aimed at evaluating the effectiveness of probiotics ingestion in changing maternal microbiota and preventing gestational diabetes in overweight and obese women.

To achieve these goals, obese (BMI> 30 kg/m^2) or overweight (BMI> 25 kg/m^2) pregnant women with risk factors were enrolled in the study and randomized to the supplementation with the probiotic VIVOMIXX® or with placebo.

The endpoints of this study are to evaluate if the dietary supplementation with the probiotic VIVOMIXX® modifies the maternal fecal microbiota (bifidobacteria and lactobacilli) and related enzymatic activity (alkaline sphingomyelinase and alkaline phosphatase), and if this if this is linked to an improvement of the intermediate metabolism (positive Oral Glucose Tolerance Test at 24-26 weeks).

Read the detailed description

This is a prospective, multicenter, randomized, double-blind, placebo-controlled trial.

208 pregnant women from the recruiting centers will be enrolled as follow: Women eligible to participate, prior informed consent, will be randomized to 2 capsules twice daily before breakfast and before dinner from randomization until delivery. The boxes will be given to the patients coded and blinded to investigators and participants, and will contain either the active ingredient (VIVOMIXX®, a mixture of 112 billion of eight strains for each capsule, namely Streptococcus thermophilus, bifidobacteria (B. breve, B. longum, B. infantis) and lactobacilli (L. paracasei, L. acidophilus, L. delbrueckii subsp bulgaricus, L. plantarum) or placebo.

The protocol includes a screening visit (Visit 1) at 10-12 weeks, two visits during pregnancy (at 26-28 weeks= Visit 2, and at 36-38 weeks=Visit 3) and a postnatal visit (2-3 days after delivery=Visit 4).

Eligible women should take two capsules twice daily (2 in the morning and 2 in the evening). Patients will be randomly assigned to the control or the VIVOMIXX® group.

The study agent VIVOMIXX® as well as the placebo will be supplied by "Mendes SA" for the whole study period.

During Visit 1 (at 10-12 weeks) written consent will be obtained, after information on expected benefits and possible inconveniences related to participation in the trial. Furthermore, eligible women will be asked to complete two questionnaires, one on dietary habits and one on gastrointestinal symptoms. The questionnaire on gastrointestinal symptoms will be submitted to the patients at each visit.

Height will be assessed at Visit 1, while the following parameters will be measured at each visit: weight, waits/hip circumference ratio, arterial blood pressure, plasma hemoglobin (Hb), hematocrit (Ht), fasting glycemia, fasting insulin and fasting glycated hemoglobin (HbA1c1).

A blood sample for the evaluation of homocysteine will be taken as well as urine and a faeces sample will be collected for nuclear-magnetic-resonance (NMR)-based metabolomics and intestinal microbiota analysis.

Furthermore, an Arm-band will be positioned for monitoring sleep and physical activities for one week at each visit.

At Visit 2 and 3 data regarding ultrasound examinations (Amniotic fluid index, abdominal circumference, cephalic circumference ratio) will be also collected.

Two-three days after delivery (Visit 4) data regarding the delivery (mode of delivery, gestational age at delivery) as well as the newborn (Apgar score, glycemia and serum bilirubin) were collected.

Moreover, a sample of colostrum (for NMR-based metabolomics, microbiota and high performance liquid chromatography-mass spectrometry -HPLC/MS- of vitamins analysis) and newborn faeces (for NMR-based metabolomics and microbiota analysis) sample will be collected.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Probiotic VIVOMIXX™ in people with Gestational Diabetes Mellitus in Pregnancy, Diet- Controlled and Exercise Addiction, run by University of Modena and Reggio Emilia at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 May 2016. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maternal and newborn fecal microbiota changes (bifidobacteria and lactobacilli) and related enzymatic activity (alkaline sphingomyelinase and alkaline phosphatase) modifications (time frame: At baseline, at 24-26 week, at 36-38 week, 2-3 days after delivery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 May 2016.
