Suprasorb®X+PHMB Pro vs Suprasorb®X+PHMB in Treatment of Infected Venous Leg Ulcers
- Conditions
- Venous Leg Ulcer
- Registration Number
- NCT07211243
- Lead Sponsor
- Lohmann & Rauscher
- Brief Summary
This clinical investigation will be conducted as a multicentre, open-label, randomised in parallel groups, controlled study on patients with infected venous leg ulcers.
- Detailed Description
During the screening, all patients will be assessed for inclusion and exclusion criteria and wound exudation status. Eligible patients with slight or moderate wound exudation will be randomly assigned to treatment with either Suprasorb®X+PHMB Pro or Suprasorb®X+PHMB. The patients who fulfil all other eligibility criteria but have high level of wound exudation will enter a 7-days run-in period, during which they will receive superabsorbent dressing (e.g. Vliwazell® Pro, Vliwasorb® Pro) and monitored compression therapy with Rosidal® 1C. During the run-in period they should receive appropriate treatment including systemic antimicrobial drug therapy if required. After this time, these patients should be re-assessed and in case they still fulfil all eligibility criteria, and the exudation decreased at least to a moderate level, they will be randomised to Suprasorb®X+PHMB Pro or Suprasorb®X+PHMB. In case the exudation would not decrease within this period or other eligibility criteria are not met anymore, they will be screened out.
Upon randomisation, all patients will receive the assigned dressing for 21 (±2) days, or till the complete epithelialization, if it occurs earlier. The patients should also continue to receive adequate compression and, if necessary, systemic antimicrobial drug therapy. During the study participation, selected parameters of the wound will be assessed at Baseline, Interim Visit, and EOT visit. In addition, dressing changes may be performed in-between on as needed basis. After 3 weeks of treatment with Suprasorb®X+PHMB Pro or Suprasorb®X+PHMB, all patients will complete the study. Their further treatment (if necessary), will not be the part of the study.

- PARALLEL
- Primary Outcome Measures
Name Time Method Rate and severity of maceration after 3 weeks of treatment with Suprasorb®X+PHMB (Pro) 3 weeks on a 4-grade scale there 0 means no maceration and 4 means severe maceration
- Secondary Outcome Measures
Name Time Method Wound area change over time 3 weeks in mm2
Change of necrotic & fibrinous & granulation tissue rate in the wound bed 3 weeks in %
Change of wound infection status 3 weeks by a TILI (Therapeutical Index for Local Infections) score with a range 1-6. TILI \< 5 indicates a wound without infection, whereas TILI ≥ 5 means a local wound infection.
Product safety (rate of product-related complications) 3 weeks by rate of product-related complications
Change of wound exudation and presence of peri-wound oedema 3 weeks by the investigators' assessment of exudation grade
Change in patient's pain 3 weeks By NRS (numeric rating scale), with zero meaning "no pain" and 10 meaning "the worst pain imaginable"
Product usability 3 weeks by user and patient questionnaire
Change in patient's quality of life 3 weeks by Wound QoL-17 (wound quality of life) questionnaire
Oedema chamge 3 weeks by measurement of limb circumference
Sub-bandage pressure levels retention 3 weeks difference of the pressure levels, measured at the time of application and before the next dressing change with a wireless sensor
