NCT04101201

Brief Summary

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

Outcome Measures

Primary Outcomes (2)

  • Quality of life assessed

    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

    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 Outcomes (9)

Study Arms (2)

µSmin® Plus

OTHER

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.

Dietary Supplement: µSmin® Plus

Placebo

PLACEBO COMPARATOR

It will be supplied by the Sponsor in an amount enough for the duration of the study. The subject will administer 1 tablet per day

Model Details: Diosmin is a naturally occurring flavonoid present in citrus fruits and other plants belonging to the Rutaceae family. It is used for the treatment of chronic venous insufficiency (CVI) for its pheblotonic and vaso-active properties, safety and tolerability as well. µSmin® Plus is a proprietary flavonoid complex with enhanced bio-efficacy. It contains highly concentrated micronized and standardized Diosmin. Highly improved bioavailability and improved oral absorption by micronization of the particles.
