Clinical Investigation of Sorbact® Dressings

NCT05089890 | Recruiting

• 1 other identifier: DHF-5474
• Study Type: interventional
• Target: 30
• Locations: 1 country
• Sites: 1

Brief Summary

The main purpose of this exploratory clinical investigation is to study the binding of bacteria and fungi from hard-to-heal wounds to the DACC-coated dressings.

Conditions

Venous Leg Ulcer; Pressure Ulcer; Diabetic Foot Ulcer; Arterial Leg Ulcer; Hard-to-heal Wounds

Outcome Measures

Primary Outcomes (1)

• Bacterial and fungal species irreversibly bound to the dressing after 2 days (+ 1 day).

  The measurements that will be used to assess the primary outcome are 16S rRNA sequencing to identify bacterial species, Internal Transcribed Spacer (ITS) sequencing to identify fungal species and scanning electron microscopy (SEM) images for visualization of bacteria and fungi bound to the dressing

  2 days (+1 day)

Secondary Outcomes (3)

• Wound bed microbial load at 14 days (±1 days) compared to baseline

  14 days (±1 days)

• Wound bed bacteria and fungi species at baseline and at 14 days (±1 days)

  14 days (±1 days)

• Wound fluid inflammatory biomarker levels at 14 days (±1 days) compared to baseline

  14 days (±1 days)

Interventions

Sorbact® Compress DEVICE

Sorbact® technology is a bacteria- and fungi-binding wound contact layer from which Sorbact® Compress has been developed. The patients will be in one of these 3 arms depending on the choice of dressing most suitable for their wounds. The purpose of the study is not to compare between the devices, but to study each device on its own.
