August 9, 2024 updated by: The Metis Foundation
This study will demonstrate the effectiveness of the NP-PWD therapy in managing complex wounds and improving wound healing parameters as compared to standard of care.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A study of 24 completed subjects will be conducted by enrolling patients who are requiring treatment for open skin and soft tissue defects. Patients will be screened for inclusion criteria and asked to consent to participate in the study. Following consent subjects will be randomized to receive treatment of one of the two study arms. Arm 1, the standard of care arm, will receive KCI Wound VAC Granulofoam. Arm 2, the study arm, will receive treatment with NP-PWD. Prior to the initial application, wound evaluations and photography will be completed to include assessment of infection with wound swabs. The wound dressing will be assessed for the need for change every 2-3 days and changed if clinically indicated (following each device IFU). Subjects will be followed for up to nine days post initial application. At minimum, the randomized treatment will be applied for 2 days after initial application for a subject to be considered completed. Subject who do not complete the treatment course (minimum of 2 days of treatment), may be replaced per investigators discretion. Follow up data will be gathered at each change/removal of the NP-PWD or Wound VAC. The data collected will include indications for dressing change, dressing change process, photographs and assessments for wound healing, infection, and adverse events. Gathered clinical data of the enrolled subjects will be used to evaluate the feasibility in using the NP-PWD device for wound healing management.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
28

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria

All subjects enrolled must meet ALL the following criteria:

  1. Patients 18 years of age or older of either gender
  2. Have an open skin or soft tissue defect requiring treatment

Exclusion Criteria

Subjects who meet any of the following criteria will be excluded from the study:

  1. Active malignant disease at the study site
  2. Any concomitant medications or co-morbidities that, in the opinion of the investigator, may interfere with device use
  3. On any investigational drug(s) or therapeutic device(s) to the study site in the last 30 days or any previous enrollment in this study
  4. Pregnant at enrollment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Feasibility and usability of device in treatment.
Time Frame: Seven to nine days post application.
The number and type of issues with the device will be documented to determine feasibility and usability. Events such as complications with application, device changes and early removal and rationale for events during the period the patient has the study device applied and throughout the entire enrollment period.
Seven to nine days post application.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Wound readiness for closure
Time Frame: Seven to nine days post application.
The treating physician will use their best medical judgment to assess the wound bed using rate of epithelization, signs of infection, exposed tendon or bone and overall appearance of the wound bed to determine the wounds readiness for closure. It will be documented the number of subjects from both groups that after treatment are ready to be grafted, or are no longer requiring surgery.
Seven to nine days post application.
Incidence of colony forming units.
Time Frame: Seven to nine days post application.
Colony forming units are assessed by obtaining wound swabs and analysis of presence of colony forming units.
Seven to nine days post application.
Ease of use of device by healthcare providers
Time Frame: Seven to nine days post application.
At each research visit the staff will be asked if they had any questions, concerns, complaints or comments about the device or dressing. There is not a separate healthcare provider questionnaire, but any information obtained will be placed in the comments section of the source documents and the feedback will be provided to manufacture.
Seven to nine days post application.
Tolerability of the device by patient subjects
Time Frame: Seven to nine days post application.
Tolerability of device by subjects will be assessed by observation of the length of time subjects were able to keep the dressing on. The subject will be asked if they have any concern or complaints about the device or dressing. Their response and if applicable the reason for removal will all be documented.
Seven to nine days post application.
