Evaluation of the Mixture Myoinositol:D-chiro-inositol 3.6:1 in Women With Polycystic Ovary Syndrome

January 9, 2019 updated by: Biosearch S.A.

Comparison of the Effect of a Combination of Myoinositol:D-chiro-inositol With Low Proportion of DCI (40:1) Versus a Combination With a Higher Proportion of DCI (3.6:1) in the Oocyte Quality and Pregnancy Rates in Women With PCOS

The aim of the present study is to evaluate the effect of increasing the proportion of D-chiro-inositol (DCI) in a combination with myo-inositol (MYO) in improving fertility in women with polycystic ovarian syndrome (PCOS). Sixty women diagnosed with PCOS will randomly take twice a day for 12 weeks a capsule containing 550 mg of myo-inositol and 150 mg of D-chiro-inositol or capsules containing 550 mg of myo-inositol and 13.8 mg of D-chiro-inositol.

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

Polycystic ovarian syndrome (PCOS) is the most prevalent endocrinopathy in women of childbearing age. It affects 4-8% of the population and of them, approximately 74% present anovulatory cycles and, therefore, fertility problems.

Both myo-inositol and D-chiro-inositol are 2 natural substances that have been shown to improve ovarian function and metabolism in women with polycystic ovarian syndrome.

The aim of the present study is to compare the effect of 2 ratios of myo-inositol /D-chiro-inositol on parameters related to the fertility of women with PCOS.

It is a multicenter, controlled, randomized, double-blind, parallel-group, 12-week clinical trial which will be conducted in 13 public and private hospitals from Spain.

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.

  • Phase 3

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

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.
