NCT05005052

Brief Summary

This study compares the efficacy and safety of sulodexide (Vessel) to placebo in patients with chronic venous disease of the lower extremities. The primary hypothesis is that more patients will achieve a decrease in rVCSS score of at least 4 points with sulodexide than with placebo.

Outcome Measures

Primary Outcomes (1)

  • Revised Venous Clinical Severity Score (rVCSS)

    A minimal decrease in rVCSS score by 4 points will be considered a clinically significant response to treatment.

    24 weeks of treatment

Secondary Outcomes (8)

  • Revised Venous Clinical Severity Score (rVCSS)

    4, 8 and 12 weeks of treatment

  • Volume in lower limb

    4, 8, 12 and 24 weeks of treatment

  • Visual Analogue Scale (VAS)

    4, 8, 12 and 24 weeks of treatment

  • Work Productivity and Activity Impairment (WPAI questionnaire)

    8 and 24 weeks of treatment

  • EQ-5D questionnaire

    8 and 24 weeks of treatment

  • +3 more secondary outcomes

Interventions

VesselDRUG

Sulodexide has protective effect on the endothelium, antithrombotic, fibrinolytic and anti-inflammatory effects. In the last 20 years, it has been well established in the common practice and its efficacy and safety have been demonstrated notably in the treatment of venous diseases such as post-thrombotic syndrome of the lower extremities, secondary prevention of deep and superficial venous thrombosis, supportive treatment of leg venous ulceration, ischemic disease of the lower limbs; symptomatic therapy of intermittent claudication, treatment of diabetic ulcers and microcirculation disorders of various aetiology. Patients with CVD were shown to respond quickly to sulodexide therapy in single arm observational studies. Sulodexide seems to provide both symptomatic and causal therapy.
