Comparison of Transforming Powder Dressing to NPIAP Recommended Standard of Care Therapies in Stage 2, 3 and 4 Pressure Injuries

November 17, 2025 updated by: ULURU Inc.

Randomized, Controlled, Open-Label, Parallel Group, Multi-Center, Prospective Phase 4 Study Comparing the Efficacy of Transforming Powder Dressing to NPIAP Recommended Standard of Care Therapies in Stage 2, 3 and 4 Pressure Injuries

Pressure injuries, commonly known as pressure ulcers, affect over 2.5 million people in the United States. Pressure injuries are classified into four escalating stages, from intact skin to full thickness wounds with deep tissue loss and exposed bone. This study will compare current standard of care treatment (as recommended by the National Pressure Injury Advisory Panel) to treatment with Altrazeal® in patients with stage 2, stage 3 and stage 4 pressure injury wounds. Altrazeal® is a Class 1, 501(k) exempt medical device listed with the FDA as a "dressing, wound, hydrogel" and has an extended wear time of up to 30 days. Subjects can be enrolled in the study either as an outpatient, or while hospitalized. Half of the subjects will be randomized to standard of care treatment, and the other half will be randomized to Altrazeal®. There are a total of up to 12 study visits taking place over 12 weeks.

Detailed Description

Pressure injuries, commonly known as pressure ulcers, affect over 2.5 million people in the United States. Pressure injuries are classified into four escalating stages, from intact skin with redness to full thickness wounds with deep tissue loss and exposed bone.

This study will focus on patients with stage 2, stage 3 and stage 4 pressure injury wounds. It will compare current standard of care treatment (as recommended by the National Pressure Injury Advisory Panel) to treatment with Altrazeal® Transforming Powder Dressing (TPD). Altrazeal® is a Class 1, 501(k) exempt medical device listed with the FDA as a "dressing, wound, hydrogel" and has an extended wear time of up to 30 days. Altrazeal® is a powder dressing that conforms to the wound, covering and protecting it, shielding the wound from bacteria. Altrazeal® is used in conjunction with a secondary dressing when needed.

The primary aim of the study is to evaluate whether dressing changes can be reduced during treatment of pressure injuries. The study will also compare wound healing between the group receiving Altrazeal® and the group receiving standard of care dressings, as well as complications, pain, quality of life, and overall costs between the two groups.

Subjects will be randomized into 2 groups, standard of care and Altrazeal®. Half of the subjects will receive current standard of care treatment, and the other half will receive treatment with Altrazeal®. This is an open-label study, meaning that both the subject and the treatment provider will know what study group the subject has been randomized to.

The first visit will be the screening visit to ensure patients meet eligibility criteria. Patients can be either an outpatient or hospitalized. Written informed consent will be obtained during this visit. A wound evaluation will be performed, and laboratory work ordered, if not done recently.

Once identified as meeting study criteria, the next visit is Baseline Visit, where randomization will occur and the first treatment will take place. Participants will be evaluated for 12 additional consecutive weeks, receiving wound evaluation, measurements, and getting treatment for the wound. A pain evaluation, quality of life survey related to having a wound, questionnaire regarding additional wound care performed between study visits. Participants will also answer questions regarding how much offloading devices or maneuvers were utilized, medications taken, and if any complications developed related to their wound care.

If the wound is healed prior to 12 weeks, the study will end when the wound is healed. Otherwise, the study will go on for 12 consecutive weeks. At the end of the study, the participant will be asked to complete a Subject Satisfaction Survey, answering questions regarding how the wound dressing worked for them. The surveys should take 5-10 minutes to complete.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Factorial Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Standard of Care Dressing for Pressure Injury
Standard wound dressings recommended by the National Pressure Injury Advisory Panel (NPIAP), according to the wound stage, will be utilized to treat pressure injuries. These include hydrocolloid, hydrogel, polymeric membranes, foam, collagen dressings, and negative pressure wound therapy. Dressings will be changed according to wound conditions, and type of dressing selected.
Device: Altrazeal® Transforming Powder Dressing
Pressure injury wounds will be evaluated at each study visit (cleaned, photographed, measured) and a dressing will be applied according to the study arm
Other Names:
  • Standard of Care wound dressings (such as foam, hydrocolloid, collagen, etc)
Active Comparator: Altrazeal® Transforming Powder Dressing
Altrazeal® Transforming Powder Dressing will be applied during the Baseline visit. It should be left in place for up to 30 days, and topped off (additional powder applied if needed) at each subsequent visit. Secondary dressing, including a contact layer over the Altrazeal® and a secondary dressing (like gauze or foam) may be applied over the contact layer.
Device: Altrazeal® Transforming Powder Dressing

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of wound dressing changes
Time Frame: 12 weeks
The number of primary dressing changes for each treatment group will be compared.
12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Wound healing
Time Frame: 12 weeks
Wound healing will be measured by using a ruler each week to report length and width of the wound. Percentage of wound area reduction will be calculated for each treatment group and compared.
12 weeks
Complications (problems) from treating the pressure wound
Time Frame: 12 weeks
Subjects will be asked to report, will be questioned and observed (by the researchers) each study visit for any complications, problems or adverse events related to the study wound that they experience, such as maceration around the wound from the drainage, moisture, or dressing. Complications and adverse events will be compared during the course of the study
12 weeks
Pain in the wound and from dressing changes.
Time Frame: 12 weeks
Subjects with sensation in the area of the wound will be asked to complete a validated visual analogue scale. This is a simple validated test asking the subject to rate their pain on a 0-10 point level, where 10 is the worst and 0 is no pain. Mean and median pain scores will be compared for each treatment group during the course of the study
12 weeks
Wound Quality of Life
Time Frame: 12 weeks
Mean and median changes in validated Wound Quality of Life scores will be measured between groups during the course of the study
12 weeks
