June 23, 2020 updated by: Giellepi S.p.A

Randomized, Double-blind, Placebo-controlled Clinical Trial to Assess the Efficacy of µSmin® Plus (Dietary Supplement) in Chronic Venous Insufficiency Symptoms Relief

This study evaluates treatment with the dietary supplement µSmin® Plus in a group of patients suffering from chronic venous insufficiency in comparison with a similarly-sized group of patients receiving placebo evaluated by quality of life questionnaires, VAS pain scale, CVI symptomatology, and change in the circumference of the affected leg at calf level

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

In this study we use a dietary supplement - µSmin® Plus - for symptomatic treatment of CVI and we will monitor its impact on CVI symptoms, features, and consequences (item) of the disease listed below: limb edema, walking, daily tasks performance, pain/burning symptoms, pruritus/paresthesis, sensation of heaviness/fatigue, time wasted in the management of the disease, social burden, disease impact on self-confidence, and its impact on physical exercise/recreational activities. Results of related clinical trials were published before showing that this is an active field in clinical reasearch.

OTHER: µSmin® Plus
µSmin® Plus is a new Micronized Diosmin Formulation for oral administration. Diosmin is extremely well tolerated and safe to use. Diosmin is safe for most people when used short-term for up to 6 months. During the 8 weeks of the clinical investigation, the subject will administer 1 tablet of µSMIN® Plus (corresponding to 450 mg of micronized diosmin) or placebo per day.

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
Quality of life assessed
Time Frame: 56 days
Quality of life is assessed by ChronIc Venous Insuficiency quality of life Questionnaire ( CIVIQ-20 questionnaire ). The 20-item questionnaire, provides a global index and an outline of 4 quality-of-life dimensions-"pain" (4 items), "physical" (4 items), "psychological" (9 items), and "social" (3 items). Items on the CIVIQ-20 scale were scored from 1 to 5. There are 20 questions in the CIVIQ-20, each with 5 possible answers (1 to 5), the minimum possible score being 20 and the maximum 100. In order to calculate the GIS, the difference between the final score and the minimum possible score is to be divided by the difference between the theoretical maximum and minimum scores (100-20=80), multiplied by 100. A low score will correspond to greater patient comfort.
56 days
Change in the circumference of each affected leg
Time Frame: 56 days
To evaluate the efficacy of the dietary supplement µSmin® Plus on ameliorating the symptoms of Chronic Venous Insufficiency in terms of change in the circumference of affected legs and quality of life, in comparison with placebo, from baseline to week 8 visit; The unit for this measurement is centimeter.
56 days

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
Visual Analogue Scale ( VAS scale ) from 0 to 10 for pain measurements
Time Frame: 56 days
Visual Analogue Scale is a straight horizontal line of 100 mm. The ends are defined as the extreme limits of the pain (symptom, pain, health) orientated from the left (worst) to the right (best). Using a ruler, the score is determined by measuring the distance in millimeters on the 10 centimeters line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity and a low score indicates a low pain intensity.
56 days
Symptoms relief assessed by Venous Clinical Severity Score (VCSS) questionnaire
Time Frame: 56 days
Venous Clinical Severity Score use the progressive ranking of severity, while weighting the upper levels representing the more severe presentations of Chronical Venous Disease. The lowest possible score is 0=absent meaning that the patient has no symptoms and the highest possible score is 30=sever meaning that the patient has a very severe venous symptoms.
56 days
Investigator Global Assessment of the efficacy by scoresproduct
Time Frame: 56 days
Efficacy of treatment: Percentage of physicians who rated 1= excellent, 2 = good, 3= fair, 4= poor
56 days
Patient Global Assessment of the efficacy by scores
Time Frame: 56 days
Patients satisfaction: 1= very satisfied, 2= satisfied, 3 = adequate, 4= unsatisfied, 5 = very unsatisfied
56 days
Percentage of subjects who would want to continue with µSmin® Plus.
Time Frame: 56 days
By this outcome we want to find out the percentage of patients who will want to continue with µSmin® Plus.
56 days
Percentage of subjects who experienced symptoms relief
Time Frame: 56 days
Percentage of subjects who experienced symptoms relief within the first week of intake, within 2 weeks of intake, or more than 2 weeks of intake;
56 days
Treatment compliance
Time Frame: 56 days
Variable medication possession ratio (VMPR) will be used to calculate the compliance (or adherence) to the treatment in the two groups collected by diary card and used and unused products
56 days
AE/SAE incidence
Time Frame: 56 days
Evaluation of safety during all the study period through AE/SAE collection
56 days
Investigator Global Assessment of Safety (IGAS):
Time Frame: 56 days
Investigator Global Assessment of Safety (IGAS): using the 4-point scale:1= very good safety, 2 = good safety, 3 = moderate safety and 4 = poor safety. IGAS will be evaluated at the last visit.
