Short-Term Safety and Performance of Two Wound Dressings Evaluation (POLTX_Fiber)
A Post-Market Clinical Follow-Up Study to Evaluate Short-Term Safety and Performance of POLTX_Fiber Compared With Suprasorb Liquacel Pro in Chronic Wounds
Chronic wounds, including venous leg ulcers, diabetic foot ulcers, and pressure ulcers, are defined as wounds that fail to heal within 4-8 weeks despite appropriate care. They represent a significant health burden due to prolonged healing, risk of infection, recurrence, and impact on quality of life and healthcare costs. Their development is multifactorial and often linked to vascular impairments, which reduce oxygen and nutrient supply. This leads to impaired tissue repair, persistent inflammation, and increased susceptibility to infection.
Standard treatment includes wound debridement, infection control, maintaining a moist environment, and managing pain and exudate. POLTX_Fiber is an absorbent gelling fiber dressing designed to improve moisture balance, manage exudate, and reduce bacterial load, with established safety and CE marking.
A post-market clinical follow-up study will compare POLTX_Fiber with Suprasorb® Liquacel Pro over a 30-day period in an outpatient setting. The study evaluates wound healing, infection status, usability, pain, and patient satisfaction. It is conducted in accordance with EU and Swiss regulations, ensures qualified investigators, and considers sex and gender differences in the analysis.

Szczegółowy opis
Chronic wounds, including venous leg ulcers, diabetic foot ulcers, and pressure ulcers, represent a growing healthcare burden, associated with delayed healing, high recurrence rates, and reduced quality of life. Their pathophysiology is multifactorial, involving impaired perfusion, dysregulated inflammation, and bacterial colonization, all of which contribute to prolonged healing.
Effective wound management requires control of exudate, maintenance of a moist wound environment, and management of microbial burden. Absorbent gelling fiber dressings are commonly used for this purpose; however, comparative clinical evidence between available products remains limited.
POLTX_Fiber is a CE-marked absorbent gelling fiber dressing intended to support exudate management and wound healing. Additional clinical data are needed to further evaluate its performance under routine clinical conditions, in line with post-market clinical follow-up (PMCF) requirements under Regulation (EU) 2017/745.
This study aims to evaluate the clinical performance and safety of POLTX_Fiber in patients with chronic wounds in an outpatient setting, compared with a standard gelling fiber dressing. The primary objective is to assess changes in wound surface area over a 30-day treatment period. Secondary objectives include evaluation of wound condition, patient outcomes, and device usability.
This is a multicenter, non-randomized, controlled, open-label PMCF study conducted in outpatient care. Eligible patients will receive either POLTX_Fiber or a comparator dressing as part of routine clinical practice.

Photographic evaluation
Ramy czasowe: 12 Weeks
|
Standardized photographs will be obtained using ImitoWound® after dressing removal, wound debridement (if applicable) and wound cleansing at a frequency of no more than once per week, even if multiple dressing changes take place during the same week. ImitoWound® will be used in an iPad as instructed in supplier's wound imaging and measurement guidelines. The camera of the iPad will be maintained 20 to 30 cm away from and parallel to the wound. A calibration marker (quick response [QR] code) will be positioned next to and in the same plane of the wound, and a photograph will be taken after recognition of the QR code by ImitoWound®, providing automatic wound measurements. This marker will allow standardised image captures maintaining fixed distance, lighting, and calibration. Study nurses will receive concise training and a working instruction with step-by-step procedure on how to use ImitoWound®. Images will be anonymized and centrally reviewed by two blinded assessors; discrepancies > |

Change in wound area
Ramy czasowe: 12 weeks
|
Wound area (length, width, depth, area) will be recorded using ImitoWound®. Percent wound area reduction (PWAR) from baseline to EoT (Day 30) or follow-up (Week 8 and Week 12) will be computed automatically using the following formula: PWAR = [(Wound area at baseline - Wound area at follow-up) / Wound area at baseline] × 100. Higher percentages indicate faster healing. Where digital imaging is unavailable, manual planimetry measurements may be used and documented. |

Change in wound tissue composition
Ramy czasowe: 12 weeks
|
Change from baseline in wound tissue composition, as assessed using digital wound assessment technology.
Tissue composition (e.g.
granulation, slough, necrosis) will be determined automatically through ImitoWound® image analysis at baseline and when wound images are captured during wound care.
Results will be expressed as a percentage of total wound area (sum = 100%), enabling consistent quantification of healing dynamics over time.

Local Infection Assessment
Ramy czasowe: 12 weeks
|
Local infection will be evaluated at each visit using the Therapeutic Index for Local Infection (TILI), a validated clinical tool for early infection detection (erythema, peri-wound oedema, malodour, exudate change, pain). A TILI score ≥ 5 indicates clinically relevant infection requiring medical evaluation or treatment adjustment. |
