Clinical Trial Summary

The goal of this study is to test a new gelling fiber wound dressing with silver on patients with a venous leg ulcer

Participants will be asked to wear the test dressing in a four weeks period (+/- 2 days) consisting of 6 study visits, and will have the dressing changed once pr. week at the research facility. The wound will be cleaned, assessed and photos will be uploaded to a digital software system.

Description:

: The clinical investigation is a non-comparative, one-armed, open-labelled, multi-centre study

The test product, Biatain Fiber Ag is a non-CE-marked gelling fiber wound dressing, containing silver. The product is intended for moist wound healing and exudate management of moderate to high exuding wounds.

The overall purpose of this investigation is to obtain clinical data supporting effectiveness of Biatain Fiber Ag to obtain the CE-mark in EU.

The total study duration for the subject will be approximately four weeks, consisting of a four-week test period and 6 study visits (V0/V1, V2, V3, V4 and V5). V5 will also terminate the 4-week study period.

The primary endpoint is Mean area wound reduction. The endpoint is used to evaluate clinical performance in terms of relative wound area reduction as an indication of total wound healing.

Eligibility

Inclusion Criteria:

1. Has signed informed consent

4. Has a venous leg ulcer that has failed to progress along the expected wound healing trajectory within 4 weeks

5. The shape of the wound should be possible to fit under a 10x10 cm dressing

6. The shape and location of the wound should be suitable for photo capture (assessed by the investigator).

7. Has at least three of five pre-defined clinical signs of infection; pain between two dressing changes, peri-ulcer skin erythema/inflammation, oedema, malodour, or heavy exudate (assessed by the investigator).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean relative wound area reduction as indication of total wound healing	Wound area will be measured by obtaining photos of the wounds and measure these afterwards. A planimetric software will be used where the wound is photographed with a ruler of known dimensions placed at the skin near the wound edge and the image is transferred to a computer and opened in the planimetric software. The ruler is used for calibration of linear dimensions at the image. Once the wound border is manually traced with a computer mouse the area of wound is calculated and displayed.	period of 4 weeks
