A Prospective, Randomized Controlled Study of the Probiotics as Adjuvant Treatment for Bacterial Vaginosis

June 9, 2025 updated by: Shangrong Fan, Peking University Shenzhen Hospital

Department of Obstetrics and Gynecology, Peking University Shenzhen Hospital

The investigators are trying to determine if oral Probiotics(Umeta-mimi,30 days) with Metronidazole vaginal suppositories (7 days) is better than using Metronidazole vaginal suppositories(7 days) only in preventing the recurrence of bacterial vaginosis

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Studies have shown that oral Probiotics(Umeta-mimi) can significantly promote the recovery of vaginal flora mainly because intestinal microbiota can migrate and affect vaginal microecology. This project aims to evaluate the efficacy of oral Probiotics(Umeta-mimi,30 days) with Metronidazole vaginal suppositories(7 days) in the treatment of bacterial vaginosis (BV) and to explore the correlation between vaginal flora and fecal flora by detecting the metagenomics of vaginal secretions and intestinal feces at the time of baseline phase,14 days after treatment， the first month after treatment, 5-7 days after third menstruation after treatment and 5-7 days after sixth menstruation after treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
