Diosmin has a well established use status in improvement of the symptoms of venolymphatic insufficiency: heavy legs, pain, primo-decubitus restlessness and as complement treatment of capillary fragility.

Nevertheless, diosmin 600 mg did not benefit from a rigorous clinical study versus placebo, to establish its efficacy in the pain relief in Chronic Venous Disease (CVD).

The aim of this project led by Dr. Guex is to evaluate the efficacy and safety of diosmin 600 mg - DIOVENOR® on the painful symptoms of CVD of the lower limbs, in a multicentre, controlled, randomised, double blind, placebo-controlled, parallel-group study.

Condition Intervention Phase
Chronic Venous Disease of Lower Limbs Drug: Diosmin Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Assessment of the Efficacy and Safety of Diosmin 600mg on Painful Symptomatology in Patients With Chronic Venous Disease of Lower Limbs: a Multicentric, Randomised, Double-blind, Placebo-controlled Trial in Parallel Groups

Further study details as provided by Laboratoire Innotech International:

Primary Outcome Measures:
  • Change of Visual analog Scale score for assessment of the painful venous symptomatology [ Time Frame: baseline and after 28 days ]

Secondary Outcome Measures:
  • - Painful symptom intensity (daily VAS score) Area Under the Curve [ Time Frame: 28 days ]
  • - Daily VAS score for Response rate [ Time Frame: 28 days ]
  • - Daily VAS score for Time to response [ Time Frame: 28 days ]
  • - Score of Quality of life questionnaire (SQOR-V) [ Time Frame: Between baseline and 28 days ]
  • - Patient's and physician's global satisfaction score [ Time Frame: At 28 days ]
  • Adverse Events (numbers and frequency) [ Time Frame: 28 days ]
  • - Unusual intakes of analgesic treatments (rate of patients) [ Time Frame: 28 days ]
