Primary purpose: TREATMENT

Brief summary: Negative pressure wound therapy (NPWT) is widely used for chronic and acute wounds, severe burns, and post-operative care. Despite its benefits, the strong adhesive required to maintain an airtight seal increases the risk of medical adhesive-related skin injuries (MARSI), pain, and discomfort during removal. Global Biomedical Technologies (GBT) aims to develop an NPWT drape with "switchable adhesive" technology to enhance removal while maintaining an effective seal. This innovation is expected to benefit both single-use and serial-use NPWT applications by reducing MARSI and improving patient comfort.

This project will compare the functionality and acceptability of Comfort Release® NPWT drapes with the industry-standard V.A.C. drape (KCI Technologies, Inc.) in a non-blinded randomized controlled trial.

Specific Aims Aim 1: Compare Comfort Release® drapes with V.A.C. drapes in single-use NPWT applications in post-surgical patients (n=200) at Columbia University Medical Center and Weill Cornell Medical Center.

Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C. drapes in:

Reduction of MARSI (Medical Adhesive-Related Skin Injury scoring system) Decreased pain (Indiana Polyclinic Combined Pain Scale) Reduced need for pain/anxiety medication Equivalent or improved seal effectiveness (leak incidence rate) Clinician acceptability Aim 2: Compare Comfort Release® drapes with V.A.C. drapes in serial-use NPWT applications in chronic wound patients (n=100) at Weill Cornell Medical Center. Patients will undergo three NPWT drape changes per week.

Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C. drapes in:

Reduction of MARSI Decreased pain (Indiana Polyclinic Combined Pain Scale) Improved compliance with treatment duration Reduced need for pain/anxiety medication Equivalent or better seal effectiveness Clinician acceptability (questionnaire score \>4) Reduced nursing time by ≥20% Economic value through time and cost savings

At each dressing change and final removal, qualitative data from clinicians will assess the acceptability and usability of Comfort Release® NPWT drapes.

Detailed description: Study Overview: Two-Aimed NPWT Drape Clinical Trial

Global Biomedical Technologies is advancing a novel surgical drape for negative pressure wound therapy (NPWT) that leverages Comfort Release®-a "switchable adhesive" technology designed for painless and trauma-free removal. This innovative adhesive incorporates oligo(glycerol sebacate) (OGS) and polyacrylate, allowing strong bonding during use and rapid release upon exposure to isopropyl alcohol (IPA). This product addresses the unmet need for effective NPWT adhesives that prevent medical adhesive-related skin injuries (MARSI) without compromising performance.

Key Features of Comfort Release® Adhesive:

* Composition: OGS, a biodegradable elastomer pre-polymer, forms hydrogen bonds with IPA, enabling adhesive release.
* Performance: A \>70% drop in adhesive strength within 5 seconds of 70% IPA application.
* Benefits: Reduces pain and trauma at removal, maintains effective NPWT seals, and improves patient outcomes.

This Direct-to-Phase II study compares the Comfort Release® NPWT drape with the market leader, V.A.C. drape (KCI Technologies, Inc.), focusing on clinical performance, patient outcomes, and clinician feedback.

Study Objectives:

1. Evaluate Performance: Assess the skin irritation, pain, seal effectiveness, and clinician usability of the Comfort Release® drape.
2. Provide Clinical Validation: Gather data for FDA 510(k) clearance, supporting the introduction of a novel NPWT adhesive drape to the market.

   Purpose:

   NPWT is commonly used for the management of more than 100 indications, including chronic wounds, acute open wounds, burns, and post operative sites. An estimated 6.5 million patients suffer from chronic wounds and an estimated 48 million inpatient surgeries are performed each year in the US3,4. NPWT involves covering a wound with an airtight dressing, sealed by adhesive, and applying sub-atmospheric pressure via a vacuum device. Strong adhesives are typically required for NPWT drapes. Exudate can leak with weaker adhesives, tainting peri-wound skin, causing loss of drape adherence, subsequently leading to the potential for macerated tissue, increased wound size, and slower or reduced healing. However, strong adhesives substantially increase the risk for medical adhesive-associated skin injuries (MARSI) during drape removal/changes. Drape removal can cause epidermal layers to separate and/or detach from the dermis, resulting in skin tears and moisture-associated skin damage, and skin irritation. Studies show the type of drape used correlates with acute pain during dressing changes and injury to the peri-wound tissue, in turn delaying the wound healing process. Previous attempts to develop a product with strong adhesion and easy removability have fallen short. Silicone adhesives have poor skin adherence and are expensive, thus requiring stronger adhering acrylic sealing strips or other acrylic components to mitigate leaks. Addressing this unmet need, Global Biomedical Technologies has developed an adhesive acrylic NPWT drape incorporating innovative ester oligomers that release from the skin with the addition of isopropyl alcohol. This painless adhesive technology, "Comfort Release®," has proven high patient satisfaction with low incidence of MARSI. This project will confirm the superior functionality and acceptability of Comport Release® NPWT drapes against the market leader (V.A.C. drape by KCI Technologies, Inc.) in both single-use and serial-use NPWT applications. The data obtained from this Direct to Phase II project is expected to support a 510K FDA clearance.

   The proposed research aims to provide the clinical validation and data needed for a510K FDA clearance. If successful, the knowledge gained as a result of this trial can bring to market a novel surgical drape for wound therapy that has strong potential to be pain-free and atraumatic and will help facilitate wound healing. This can potentially contribute to improved patient outcomes. Given that there are minimal risks in this trial we find them reasonable to obtain the knowledge and clinical data needed bring this drape to pursue FDA clearance and bring this novel NPWT drape to market.

   Addressing this, Global Biomedical Technologies will compare Comfort Release® NPWT drape with an innovative "switchable adhesive" technology for painless and trauma free removal with the standard KCI V.A.C.® drape in post-surgical wound patients. The types of post-op wounds that receive NPWT that are eligible for this study include adult acute wounds and incisions, as well as chronic wounds and burns.
