Clinical Trial Summary

This study will evaluate the use of a mattress overlay system to promote the healing of full thickness pressure ulcers. The overlay is placed over the patient's bed making it easier for patients to get in and out of bed. In addition, the overlay has blue tooth capabilities that will allow clinicians to remotely monitor adherence with the device.

Description:

The study is a multi-center, prospective, study designed to evaluate the use of an alternating mattress overlay in the treatment of stage 3 pressure ulcers. After screening, eligible subjects will receive a mattress overlay system for the 4 weeks of treatment. The mattress is fitted to the patient's bed/mattress in his/her home or skilled nursing facility (SNF). Patients responding to the offloading regimen (percent wound area reduction >20% at 4 weeks) may use the overlay for up to 12 additional weeks. The SOC in this study is debridement, proper moisture balance, reduction of bacterial burden and nutritional counseling.

Subjects with a history of more than two weeks treatment with immunosuppressants (including systemic corticosteroids >10mg daily dose), cytotoxic chemotherapy, or application of topical steroids to the ulcer surface within one month prior to first Screening Visit, or who receive such medications during the screening period, or who are anticipated to require such medications during the course of the study.

7. Index ulcer has been previously treated with tissue engineered materials (e.g. Apligraf® or Dermagraft®) or other scaffold materials (e.g. Oasis, Matristem) within the l 30 days preceding the first treatment visit.

8. Affected extremity requiring hyperbaric oxygen during the trial or within 2 weeks of treatment visit 1.

9. Known HbA1C >12%.

10. Mini-nutritional assessment Malnutrition Indication score <17.

Intervention

Device:
• Dabir Mattress Overlay System
Dabir Surface mattress overlay system consists of a controller and a low-profile alternating pressure (AP) surface (placed over a non-powered mattress) with hundreds of air-filled geometric nodes arranged in rows. . The multiple rows of nodes inflate and deflate in alternating sequence every five minutes. During deflation phase, the skin and soft tissues experience reduced pressure/loading and enhanced perfusion. In conjunction with Standard of Care: Debridement, Proper moisture balance, off-loading, reduce bacterial burden and nutritional counseling.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Wound Reduction in Surface Area	The percentage change in ulcer size (wound area reduction) from baseline to 4 week completion	4 week
Secondary	Pain assessment	Assessment of the pain level linked to the wound, using a numeric pain scale. Numeric Pain Scale from 0-10 anchored by word descriptors at each end. A numerical scale will be used to assess pain. Subject will be asked to indicate a numerical value that best represents the pain intensity at ulcer site on a scale of 0 to 10 anchored by "word descriptors" at each end, as "no pain" on the left side and "worst possible pain" on the right side of the number line. The number 0 represents "no pain", the number 5 represents "moderate pain" and the number 10 represents the "worst possible pain". The subject indicates the level of pain intensity by selecting a number on the line that represents their perception of their current state.	4 weeks
