About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age ≥ 18 years
  • Infected* venous** leg ulcer
  • Slightly to moderately exuding wound***
  • Patient has signed informed consent
  • as per CDC definition, also TILI score ≥ 5 ** ABPI > 0.8 and < 1.2 *** patients with highly exuding wounds may be screened for a 7 days run-in period to receive superabsorbent dressing and monitored compression therapy and re-con-sidered for enrolment in case the exudation level decreases

Exclusion criteria

  • Participation in other interventional clinical trial that could interfere with the present study within 4 weeks of the randomisation and during the whole duration of this study
  • Wounds with exposed cartilage tissue (hyaline cartilage)
  • Contraindications to compression therapy (e.g.: advanced peripheral ar-terial occlusive diseases, decompensated cardiac insufficiency, septic phlebitis, phlegmasia coerulea dolens, sensation disorders of the skin)
  • Known allergy and/or hypersensitivity to any components of the study product or concomitant products (e.g. compression bandage)
  • Any other medical condition, which, by opinion of the investigator, may have impact of the success of the study treatment and / or interpreta-tion of the study results.

Treatment and study plan

PHMB-impregnated biocellulose wound dressing with additional polyethylene film on top, compression therapy, systemic antomicrobial therapy (optional)

Device

Application of a wound dressing with additional polyethylene film on top and compression therapy. Optional usage of the systemic antimicrobial therapy.

PHMB-impregnated biocellulose wound dressing without additional polyethylene film on top, compression therapy, systemic antomicrobial therapy (optional)

Device

Application of a wound dressing without additional polyethylene film on top and compression therapy. Optional usage of the systemic antimicrobial therapy.

Primary outcomes

  1. Rate and severity of maceration after 3 weeks of treatment with Suprasorb®X+PHMB (Pro)

    Time frame: 3 weeks

    on a 4-grade scale there 0 means no maceration and 4 means severe maceration

Secondary outcomes

  1. Wound area change over time

    Time frame: 3 weeks

    in mm2

  2. Change of necrotic & fibrinous & granulation tissue rate in the wound bed

    Time frame: 3 weeks

    in %

  3. Change of wound infection status

    Time frame: 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.

  4. Product safety (rate of product-related complications)

    Time frame: 3 weeks

    by rate of product-related complications

  5. Change of wound exudation and presence of peri-wound oedema

    Time frame: 3 weeks

    by the investigators' assessment of exudation grade

  6. Change in patient's pain

    Time frame: 3 weeks

    By NRS (numeric rating scale), with zero meaning "no pain" and 10 meaning "the worst pain imaginable"

  7. Product usability

    Time frame: 3 weeks

    by user and patient questionnaire

  8. Change in patient's quality of life

    Time frame: 3 weeks

    by Wound QoL-17 (wound quality of life) questionnaire

  9. Oedema chamge

    Time frame: 3 weeks

    by measurement of limb circumference

  10. Sub-bandage pressure levels retention

    Time frame: 3 weeks

    difference of the pressure levels, measured at the time of application and before the next dressing change with a wireless sensor
