Clinical Trial to Assess the Efficacy of µSmin® Plus
- Conditions
- Chronic Venous Disease
- Interventions
- Dietary Supplement: µSmin® PlusOther: Placebo
- Registration Number
- NCT04101201
- Lead Sponsor
- Giellepi S.p.A
- 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
- 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.

Group Intervention Description µSmin® Plus 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. Placebo Placebo 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
- Primary Outcome Measures
Name Time Method Quality of life assessed 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.
Change in the circumference of each affected leg 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.
- Secondary Outcome Measures
Name Time Method Investigator Global Assessment of Safety (IGAS): 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.
Percentage of subjects who would want to continue with µSmin® Plus. 56 days By this outcome we want to find out the percentage of patients who will want to continue with µSmin® Plus.
Symptoms relief assessed by Venous Clinical Severity Score (VCSS) questionnaire 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.
Visual Analogue Scale ( VAS scale ) from 0 to 10 for pain measurements 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.
Investigator Global Assessment of the efficacy by scoresproduct 56 days Efficacy of treatment: Percentage of physicians who rated 1= excellent, 2 = good, 3= fair, 4= poor
Patient Global Assessment of the efficacy by scores 56 days Patients satisfaction: 1= very satisfied, 2= satisfied, 3 = adequate, 4= unsatisfied, 5 = very unsatisfied
Percentage of subjects who experienced symptoms relief 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;
Treatment compliance 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
AE/SAE incidence 56 days Evaluation of safety during all the study period through AE/SAE collection
