Clinical Trial Summary

This is a single-centre prospective, open, non-comparative, Post-Market Clinical Follow-up (PMCF) investigation to confirm performance and safety of Exufiber® (Gelling fibre dressing) when used as intended on donor sites through assessment of wound progression from baseline to the subject´s last visit.

Description:

A single-centre prospective, open, non-comparative, PMCF investigation to confirm performance and safety of Exufiber® (gelling fibre dressing) when used as intended on donor sites. The investigation will include eligible subjects undergoing split skin graft transplantation for harvesting of a partial-thickness skin graft, i.e. excision of the epidermis and part of the dermis. After the study inclusion (baseline) the patient will go through the split skin graft transplantation following application of the Exufiber® dressing, Mepilex®(non-border) dressing, and any third dressing as required on the donor site. Each subject will thereafter be followed up on days 3, 14, and 21 prior completion in the study. A subject may complete the study prior to or on day 14 as well as in between day 14 and day 21 if the donor site is healed. Wound healing progression will be determined by the investigator/designee and assessed as: - 100% re-epithelialisation including small residual scabs/blisters and open areas less than 1 cm within an otherwise fully re-epithelialised area, and/or - less than 100% re-epithelialization but to the extent that the Exufiber dressing is not required anymore If the donor site is not healed and the donor site is dry and therefor not treatable with Exufiber the patient will be treated according to clinical praxis and followed for outcomes on the following visits. Approximately 34 eligible subjects will be included in one centre in Sweden. The primary performance endpoint will be progression of donor site wound from baseline to last visit when Exufiber is used, up to 21 days. Wound progression will be determined by the investigator/designee and will be assessed as one of the following three outcomes: - Deteriorated - No change - Improved

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in wound progress	Wound progress compared between each visit up to final visit and assessed as: Deteriorated; No change; Improved	Day 14(-1 day), Day 21(+-1 day)
Secondary	Change in wound progress	Wound progress compared between baseline and final visit up to 14 days and assessed as: Deteriorated; No change; Improved	Day 14(-1 day)
Secondary	Wound healing progress	Wound healing progress will be assessed between baseline and final visit and assesed as: - Rating percentage (%) re-epithelialisation using a visual score (0-100%). 0% is equal to no re-epithelialisation and 100% is equal to fully re-epithelialised.	Day 14(-1 day), Day 21(+-1 day)
Secondary	Follow-up assessment of wound healing when treated according to clinical praxis	Wound healing progress for subjects treated according to clinical praxis when wound is not healed and not treatable with Exufiber (dry wound) will be followed up at the final visit and assessed as: - Rating percentage (%) re-epithelialisation using a visual score (0-100%). 0% is equal to no re-epithelialisation and 100% is equal to fully re-epithelialised.	Day 21(+-1 day)
Secondary	Wound size	Wound dimension/size assessed as area using following assessments: Width (mm) Length (mm)	Day 14(-1 day)
Secondary	Change in exudate amount and type	Evaluation of the amount of wound exudate and the exudate type at each follow-up visit using the variables below: Exudate amount: High; Moderate; Low; None; Exudate type: Serous; Serousanguinous; Sanguinous; Purulent; N/A	Day 14(-1 day), Day 21(+- 1 day)
Secondary	Local infection	Presence of signs of local wound infection determined at each follow-up visit, using the variables listed below: Swelling; Redness; Heat; Fever; Pain; Foul odour	Day 14(-1 day), Day 21(+- 1 day)
Secondary	Subject's pain	Subject's pain captured using a numeric rating scale(NRS) at each follow-up visit where the patient verbally grade his/her pain on a level from 0 to 10, where 0 indicates no pain and 10 the worst imaginable pain for the subject. The NRS will be used at the following occasions: Pain before dressing removal; Pain when removing Mepilex (secondary dressing); Pain when removing Exufiber	Day 14(-1 day), Day 21(+- 1 day)
