Clinical Trial Summary

The aim of this study is to evaluate the therapeutic efficacy and the safety of the new compression system URGO BD001 in the management of venous or mixed predominantly venous leg ulcers. The therapeutic efficacy will be the reduction in wound surface area during a six weeks study treatment period.

Description:

The compression bandage URGO BD001 is indicated for the management of venous leg ulcers with ABPI (Ankle Brachial Pressure Index) ≥ 0.8, venous oedema and lymphedema justifying strong compression. The pressure applied with the compression system URGO BD001 help to improve venous return and to reduce venous oedema. The expected clinical benefits from the compression system URGO BD001 in patient with a VLU are to increase healing rate and time to healing, and to improve patient quality of life.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Relative reduction in wound surface area (percent)	Evolution between D0 and the 6 weeks treatment period with the URGO BD001 compression system: Relative reduction in wound surface area (%) = [(SW6 - SD0)/SD0] × 100 SD0: Wound surface area at D0 SW6: Wound surface area at Week 6	6 weeks
Secondary	Complete ulcer closure:	The percent (%) of patients with complete ulcer closure (100% re-epithelialization) after 6 weeks or at the latest treatment period	6 weeks or last assessment
Secondary	Venous oedema	Oedema reduction from baseline (D0) and last assessment by measuring the limb circumference (in cm), using a tape: Ankle circumference at the reference point B (smallest perimeter of the leg, 3 cm above medial malleolus,; Calf circumference at the reference point C (maximum perimeter of the calf).	6 weeks or last assessment
Secondary	Patient quality of Life (EuroQoL 5D-5L)	EuroQoL 5D-5L between baseline and at last visit. The questionnaire essentially consists of a descriptive system including 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression, and a visual analogue scale (EQ VAS) from "the worst health you can imagine" (0) to "the best health you can imagine" (100).	6 weeks or last assessment
Secondary	Evolution of the periwound skin	Evolution of the peri-wound skin at each visit according to the following parameters: Healthy; Altered: Erythematous and/or squamous (irritated dermatitis/eczema), maceration, other	6 weeks or last assessment
Secondary	Safety analysis	Nature and number of adverse event related to the use of the testing compression system (serious/ non-serious)	6 weeks or last assessment
