Overview
Brief Summary
The goal of this clinical trial to follow the progress of wounds in those with chronic venous leg ulcers while using a non-bordered foam dressing. The main objective is to follow the progress of these wounds over time from initial visit to each follow-up visit.
Participants will be asked to wear the dressing for up to 6 weeks of treatment or until healed, changed at every one-week interval.
Detailed Description
This investigation is designed as a prospective, open, multi-center, interventional, non-comparative investigation with the aim to follow chronic wound progression for 6 weeks according to local standard of care. Wound progress is a summary endpoint of the total effect of treatment using the non-bordered foam dressing as the absorbent dressing and includes the changes in an objectively measured wound area and subjectively evaluated wound condition. The only included indication is Venous Leg Ulcers (VLU). A total of n=20 participants will be recruited at up to 6 centers within the US and Canada. There will be a total of seven (7) visits to the investigation site for participants during the treatment period: baseline, followed by weekly visits up to six (6) weeks post baseline. During visits, evaluations will be performed to assess wound progression and status, wound dressing properties, as well as Subject pain, comfort, and quality of life. Safety will be assessed at all visits. One target wound per participant will be included in this investigation.

Outcomes
Primary Outcomes
Wound progress of the total effect of treatment using ALLEVYN Non-Adhesive
Time Frame: From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.
Wound progress is the total effect of treatment using ALLEVYN Non-Adhesive as the absorbent dressing and includes the changes in an objectively measured wound area and subjectively evaluated wound condition by the treating investigator/designee. Wound progress will be assessed as deteriorated, no change, improved, or healed at each visit. Wound area will be measured by an independent evaluator assisted by digital software at each visit and recorded as cm2 using the formula, A= π\*L\*W/4.
Secondary Outcomes
- Percentage wound area reduction over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Wound pain score related to removal of dressing over time (PRO)(A maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Linear wound healing over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Wound/Peri-Wound itch score prior to dressing removal over time (PRO)(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)

- Change in exudate amount over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Change in exudate nature over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Change in peri-wound skin condition over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
- Change in maceration over time(From baseline visit to last follow-up visit, a maximum total treatment period of 44 days or until healed, whichever occurs first.)
