Effect of Metformin and Probiotics in Reproductive-aged Patients With Polycystic Ovary Syndrome: a Randomized, Parallel Study

The purpose of this clinical trial is to evaluate the safety and effectiveness on the clinical and biological parameters of reproductive-aged PCOS women after a 12-week metformin and/or probiotics administration.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

Probiotics are live bacteria that offer a health benefit to the host when administered in adequate amounts. Probiotic supplementation is safe for use and has demonstrated beneficial effects for metabolic diseases such as obesity and diabetes. In this study, about 90 reproductive-aged women with PCOS will be enrolled. Participants will be randomly assigned into one of the following three groups: Metformin tablets (0.5g tid po), ProMetS probiotics powder (4g qN po), Metformin tablets (0.5g tid po) and ProMetS probiotics powder (4g qN po), for 12 weeks. Blood and stool samples will be collected before and after treatment. Fasting glucose levels, fasting insulin levels, sex hormone levels, serum lipid profiles, inflammation markers, other metabolic related parameters and change of gut microbiota and immune cells will be evaluated.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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.
Outcome Measure
Measure Description
Time Frame
Improvement in menstrual cycle
Time Frame: 12 weeks
Patients will be required to maintain a menstrual calendar and record their basal body temperature for the duration of the study and asked to fill a questionnaire before and after study. The questionnaire will cover menstrual cycle dates, duration and amount.
12 weeks
Improvement in hirsutism
Time Frame: 12 weeks
Modified Ferriman and Gallwey score (m-FG scores) will be measured before and after study. M-FG score > 8 is considered hirsutism and when the score is higher, the symptom is more serious.
12 weeks
Improvement in acne score
Time Frame: 12 weeks
Visual assessment of acne using "mild/moderate/severe" grades will be assessed before and after study.
12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
