About this study

The overarching goal of this project is to compare the microbiome profiles of healthy pregnant women, both before and after the introduction of a probiotic supplement into the maternal diet. Specifically, the investigators are performing a pilot randomized double-blinded placebo-controlled trial, comparing the microbiome profiles of 40 healthy pregnant women randomized to receive an oral probiotic containing a mixture of Lactobacillus and Bifidobacterium species (20 mothers) versus an oral placebo (20 mothers) during the first/second trimester of pregnancy. For each mother, the investigators will collect biospecimens from the vagina, rectum, and urine, both before intervention, and 4-6 weeks after intervention. These biospecimens will be analyzed to obtain their microbiome profiles using next-generation sequencing. The primary outcome of interest is the vaginal microbiome, with secondary outcomes including the microbiomes of the rectum and urine. Additionally, the investigators will collect clinical data from the mother's and infant's medical records to correlate our findings with pregnancy and postnatal outcomes.

Questions about this trial

What is this clinical trial studying?

A study testing Probiotic in people with Pregnancy Related, run by University of California, San Diego at 3 sites in United States.

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 3 inclusion and 19 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: finished, as of the sponsor's last update on 11 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. 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?

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?

Change in Vaginal Microbiome, 16S rRNA (time frame: Baseline, and 4-6 weeks after intervention). 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 Apr 2019.
