Evaluating a new dressing for managing chronic and acute wounds

A Clinical Evaluation of a New NPWT Dressing

This study is testing a new type of wound dressing to see if it helps people with chronic and acute wounds heal better and experience less pain during treatment.

Quick facts

• Study type: Observational
• Enrollment: 42 (estimated)
• Ages: 18 Years and up
• Sex: All
• Sponsor: Smith & Nephew, Inc. (industry)
• Locations: 1 site (London, Ontario)
• Trial ID: NCT06306716 on ClinicalTrials.gov

What this trial studies

This study aims to assess the clinical performance of a new Negative Pressure Wound Therapy dressing, specifically the RENASYS Film with AIRLOCK Technology, in treating chronic and acute wounds. The primary focus is on measuring the percentage of wounds that progress to healing by the end of the treatment period. Additionally, the study will evaluate the amount of granulation tissue formed, the pain experienced during dressing changes, and the safety of the device by monitoring adverse events and deficiencies.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and over with chronic or acute wounds suitable for management with Negative Pressure Wound Therapy.

Not a fit: Patients with wounds not indicated for Negative Pressure Wound Therapy or those unable to comply with study requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved healing outcomes for patients with chronic and acute wounds.

How similar studies have performed: Previous studies on Negative Pressure Wound Therapy have shown promising results, indicating that this approach is supported by existing evidence.

Eligibility criteria

Inclusion Criteria:

* Subject has provided written informed consent.
* Subject is 18 years of age or over.
* Subject is able and willing to comply with study requirements.
* Subject is suitable to participate in the study in the opinion of the Investigator. .
* Subject has a wound(s) that, per Instructions for Use (IFU), is indicated and suitable for management with NPWT and fits one of the following wound types: a. Chronic\* (this may include Diabetic Foot Ulcers (DFUs), Venous Leg Ulcers (VLUs), Pressure Ulcers but this is not an exhaustive list) b. Acute (this may include traumatic and dehisced surgical wounds and partial thickness burns) \*Chronic wound(s) in this study is defined as any wound of less than three months duration that is not healing after thirty (30) days of standard care and having addressed the underlying cause
* Subject's wound to be treated is of a size that can be managed with one of the available sizes of the study device

Exclusion Criteria:

* Subject has hypersensitivity to the use of the RENASYS NPWT System or its components, or a contraindication per the IFU such as: a. exposed arteries, veins, organs, or nerves b. necrotic tissue with eschar present (unless adequately debrided) c. non-enteric and unexplored fistulas d. exposed anastomotic site e. malignancy in the wound
* Subject participation in the treatment period of another clinical trial within thirty (30) days of baseline visit or during the study.
* Subject has skin features (e.g., tattoos, pre-existing scarring, etc.) which in the opinion of the investigator will interfere with the study assessments.
* For lower extremity wounds\*\*, any subject with a wound on a limb with an inadequate arterial supply confirmed by one of the following within 14 days of treatment:

  1. Ankle Brachial Index (ABI) \<0.7
  2. Toe Brachial Index (TBI) \<0.5
  3. Great toe pressure \<40mmHg
  4. Abnormal triphasic or biphasic waveform patterns at the ankle \*\*This criteria is not applicable for patients having an above, or below knee amputation.
* Any subject that meets the definition of a Vulnerable Subject per ISO 14155 (i.e., individuals who are unable to fully understand all aspects of the investigation that are relevant to the decision to participate, or who could be manipulated or unduly influenced as a result of a compromised position, expectation of benefits or fear of retaliatory response). Ethnic minorities will be included providing they meet other inclusion criteria.
* Subject has had the target wound for greater than three months.
* Subject has a target wound that measures \<3 millimeters (mm) in maximum depth.
* Subject has untreated osteomyelitis
* Subject has active, untreated soft tissue infection.
* Subject has wounds that has been managed with NPWT in the previous four (4) weeks
* Subject has participated previously in this clinical trial.
* Subject has a history of poor compliance with medical treatment.
* Pregnancy at time of enrolment.
* Subject has a medical or physical condition that in the opinion of the Investigator would preclude safe subject participation in the study.
