To assess the efficacy, safety and acceptability of a new TLC-NOSF dressing with poly-absorbent fibres in the management of exuding leg ulcers, at the different stages of healing. Method: This work presents the results of two prospective, multicentric clinical studies: NEREIDES and CASSIOPEE. Patients with a non-infected, moderate-to-strongly exudating leg ulcer of venous or mixed origin, were treated with the dressing and an appropriate compression system for 12 weeks. The wounds included in NEREIDES had to be in debridement stage, and those in CASSIOPEE at granulation stage. In both studies, the primary outcome was the relative wound area reduction (RWAR) at week 12. Main secondary outcomes included healing rate, time-to-reach wound closure, adverse events and acceptability of the dressing by patients and health professionals. Results: There were 37 patients included in NEREIDES and 51 in CASSIOPEE. The two cohorts presented similar patient and wound characteristics, except from the percentage of sloughy tissue on wound bed at baseline (median: 75% NEREIDES and 30% CASSIOPEE). At week 12, the RWAR (60% NEREIDES and 81% CASSIOPEE), wound closure rates (18% NEREIDES and 20% CASSIOPEE) and mean times-to-reach wound closure (58±27 days NEREIDES and 55±23 days CASSIOPEE) supported the beneficial outcomes of the treatment in both cohorts. In patients with a wound duration ≤6 months, the wound area reduction reached 85% in NEREIDES and 81% in CASSIOPEE, highlighting the importance to initiate adequate treatment as soon as possible. The nature and frequency of the local adverse events were similar in both studies and consistent with the good safety profiles of the polyabsorbent fibres and of the TLC-NOSF dressings. The acceptability of the dressing (easy to apply, conformable and non-adherent to the wound bed at removal, with no pain or bleeding at removal) has been judged 'very good' or 'good' at each stage of the healing process, by both nursing staff and patients. Conclusion: These clinical results establish the new TLC-NOSF dressing with poly-absorbent fibres (UrgoStart Plus, Laboratoires Urgo) as an effective, safe and simple treatment for the local management of leg ulcers, at the different stages of healing and until wound closure.

V enous leg ulceration (VLU) is a common and serious medical condition, affecting 1% to 3% of the older population in Western countries. 1-3 These chronic wounds are known to be painful and distressing, with considerable impact on patients' clinical trial • sucrose octasulfate dressing • TLC-NOSF dressing • UrgoStart • venous leg ulcers quality of life (QoL). 4 Their management can be substantially expensive and time-consuming for both health-care systems and...
These clinical data support that the tested dressing is a credible therapeutic alternative for the management of chronic wounds at risk of infection with inflammatory signs suggesting heavy bacterial load.
Objective: To evaluate the efficacy, tolerability and acceptability of a new multicomponent compression system in one bandage for the local treatment of patients with venous leg ulcers (VLUs). Method: This was an international, prospective, non-comparative, clinical trial, conducted in France and Germany. Eligible participants had a VLU with a wound area of 2–20cm2, lasting for a maximum of 24 months. For a period of 6 weeks, patients were treated with a new multicomponent compression system in one bandage which was worn day and night, providing high working pressure and moderate resting pressure (UrgoK1). Clinical assessments, wound measurement and photographs were planned at weeks 1, 2, 4 and 6. The primary endpoint was the relative wound area reduction (RWAR) after 6 weeks of treatment. Secondary endpoints included wound closure rate, oedema resolution, change in patient's health-related quality of life (HRQoL), acceptability, adherence to the compression therapy, local tolerance, and physician's overall satisfaction with the evaluated compression system. Results: A cohort of 52 patients (52% female, mean age 75.4±13.0 years) with VLUs, including oedema in 58% of cases, were recruited from 22 centres. At baseline, 42 patients had already been treated with a different compression system. VLUs had been present for 5.6±4.9 months and had a mean area of 5.7±4.3cm2. After 6 weeks of treatment, a median RWAR of 91% (interquartile range: 39.4; 100.0) was achieved. Wound closure was reported in 35% of patients. A RWAR ≥40% at week 4, predictive of wound healing at 12 weeks, was achieved in 62% of patients. At the final visit, oedema present at baseline was resolved in 57% of patients. Substantial improvements in the HRQoL of the patients were reported with a decrease of the pain/discomfort and anxiety/depression dimensions. Comfort in wearing the evaluated system was reported as ‘very good’ or ‘good’ by 79% of patients, resulting in a high patient adherence to compression therapy. Compared to previous compression systems, half of the patients reported more ease in wearing shoes, and greater satisfaction and comfort with this new system. Nine non-serious adverse events related to the device or its procedure occurred in seven patients. At the final visit, the majority of the physicians were ‘very satisfied’ or ‘satisfied’ with the new compression system overall. Conclusion: The new multicomponent compression system in one bandage has been shown to promote rapid healing of VLUs, reduce oedema, improve HRQoL and to be well tolerated and accepted. It appears to be a viable alternative to existing compression systems.
