Clinical Trial Summary

The overall objective of this post market clinical follow-up (PMCF) investigation is to follow the progress of exuding chronic wounds to healing, or up to 12 weeks, whichever occurs first, consecutively using Exufiber® as primary dressing, and Mepilex® Border Flex (Mepilex Border Comfort) as primary dressing.

Description:

This investigation is as a prospective, open, non-comparative, multi-centre investigation with the aim to follow exuding chronic wound progression. The investigation will include subjects from three populations suffering from exuding chronic wounds (Venous Leg Ulcers, Diabetic Foot Ulcers and Pressure Ulcers). The target wound for all subjects will initially be treated with Exufiber® as primary dressing. As the wound progress and wound exudate production is reduced, the Exufiber will be replaced by the Mepilex Border Flex dressing. For ulcers located at sacrum or heel, the Mepilex Border Heel or Mepilex Border Sacrum will be used.

Eligibility

Inclusion Criteria:

• Provision of informed consent
• Both genders =18 years old.
• Exuding pressure ulcer, exuding diabetic foot ulcer or exuding venous leg ulcer (an exuding wound defined as one that requires highly absorbent dressing - as per clinical judgement)
• Chronic wound at least 4 weeks duration (chronic would be defined after 4 weeks).
• ABPI (within the last 3 months) =0.7 for both legs (if both present). If ABPI >1.4, then big toe pressure >60mmHg is required or an alternative measurement verifying normal distal arterial flow.
• At entry into the study, the ulcer or wound area should be 0.8 cm² - 70 cm².

Exclusion Criteria:

• Known allergy/hypersensitivity to the dressing or its components.
• Subject included in other ongoing clinical investigation at present or during the past 30 days
• Pregnancy or lactation at time of study participation.
• Target wound DFU <0.8 cm² , VLU <3 cm² , PU <1 cm² , post debridement (measured as greatest length x greatest width)
• Infected ulcer according to the judgment of the investigator defined as any wound condition requiring the prescription or continuation of systemic antibiotic therapy at recruitment.
• Other wounds within 3 cm from target wound
• Subject not suitable for the investigation according to the investigator's judgement.
