OXXYNEA® GS: Study for Glycaemia Management

September 12, 2025 updated by: Fytexia

Evaluation of Two Plant Formulations for the Management of Glycemia on Pre-diabetic Participants

The aim of this study is to develop a proof of concept establishing a causal relationship between glycemia improvement through combination of polyphenols-rich botanical extracts or polyphenols-rich botanical extracts associated with white kidney bean extract and chromimum picolinate + zinc bisglycinate with chronic supplementation. Chronic glycemia improvement will be assessed by following the evolution of HbA1c, postprandial glucose and insulin kinetics, and questionnaires. The study design is double blinded randomized with 3 arms and 29 volunteers per arm.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
87

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
HbA1c
Time Frame: 12 weeks
Evaluation of changes in the glycated haemoglobin measurements in comparison of the 3 groups
12 weeks
Post prandial glycemia
Time Frame: 12 weeks
Evaluation of changes in acute and chronic glycemia: Changes in the postprandial glucose measurements in comparison of the 3 groups after the standardized breakfast at baseline, 4th, 8th and 12th week.
12 weeks
Post prandial insulemia
Time Frame: 12 weeks
Evaluation of changes in acute glycemia: Change in postprandial insulin in comparison of the 3 groups after the standardized breakfast at baseline, 4th, 8th and 12th week.
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.
Outcome Measure
Measure Description
Time Frame
Body weight
Time Frame: 12 weeks
Change in the body weight measurements in comparison of the 3 groups
12 weeks
Dual-energy X-ray (DEXA)
Time Frame: 12 weeks
Evaluation of changes in fat mass and lean mass using a Dual-energy X-ray absorptiometry and compare amongst 3 groups
12 weeks
Magnetic resonance imaging (MRI)
Time Frame: 12 weeks
Evaluation of changes in various fat layers (visceral, subcutaneous and deep subcutaneous) using a MRI and compare amongst 3 groups
12 weeks
Short Form 12 (SF-12) questionnaire
Time Frame: 12 weeks
Evaluation of changes in responses to SF-12 questionnaire. SF-12 questionnaire is a health related questionnaire with 12 questions. The total score range from 0-100, with higher score indicating better health status.
