Clinical Trial Summary

The goal of this clinical trial is to evaluate the use of Omeza combination therapy with Standard of Care. The main question it aims to answer is:

• Can Omeza combination therapy with Standard of Care enable chronic wounds to begin a healing trajectory in a 4-week period?

Patients will be treated with:

• OCM™ Wound Matrix

• Omeza combination therapy

• Standard of Care

Description:

The goal of this clinical trial is to demonstrate that the Omeza combination therapy with Standard of Care supports chronic wounds to move from chronicity to a healing trajectory. The trial is targeting those wounds that have failed therapy prior to trial enrollment and are chronic by definition of no change in area size after 2 weeks of standard of care treatment. The inclusion and exclusion criteria applied to this chronic wound clinical trial is broadened with the intention to include all patients and outliers that would not qualify for controlled trials.

Intervention

Combination Product:
• Omeza Products Used in Combination
Subjects in this single-arm study will have the targeted wound/ulcer treated with Omeza® combination therapy which includes the use of the following products: Omeza® Lidocaine Lavage Omeza® Complete Matrix (OCM™) Omeza® Skin Protectant At each treatment (on days 0, 7, 14, 21; +/- 3 days each), the patient's intact skin around the wound/ulcer will be prepped with Omeza® Lidocaine Lavage. OCM™ will be applied directly to the wound/ulcer and Omeza® Skin Protectant will be applied to the periwound and surrounding intact skin. Treatments may be repeated during an optional 7 additional weeks (on days 28, 35, 42, 49, 56, 63, and 70; +/- 3 days each). Final assessment will be made at week 12.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Chronicity of Wound Healing	The proportion of subjects with a clinically significant improvement in Study Ulcer Exudate Assessments at 4 weeks compared to baseline assessment.	4 weeks
Primary	Change in Wound Area	Percent change in wound area at 4 weeks as measured by wound imaging software. Sub-characterization will include wounds with baseline area of greater than or less than 100?.	4 weeks
Primary	Wound Healing	The objective response rate (ORR) will be used to define effectiveness at 4 weeks. The ORR is defined as the proportion of subjects at 4 weeks that have had at least a 40% reduction in the area of the wound volume from Day 0 measurements measured by wound imaging software.	4 weeks
Primary	Wound Closure	Proportion of subjects that have had complete closure at or prior to 12 weeks of treatment.	12 weeks
Secondary	Improvement in Quality of Life	Change in the subject's Quality of Life (QoL). A numerical validated QoL scale (wound QoL Appendix F) specific for wound healing will be provided for participants to complete on a scheduled visit basis up to 12 weeks from Day 0.	12 weeks
Secondary	Reported Pain Perception	Reported changes in pain perception will use a 10 cm Visual Analogue Scale and subjects will mark on the line from no pain to worst pain possible each scheduled visit.	12 weeks
Secondary	Drainage/Exudate and Infection	Change in drainage/exudate and infection assessments. Drainage/exudate and infection assessment will be provided by the investigator in assessment of wounds at each week when changing dressings at each visit.	12 weeks
Secondary	Enhanced Activities in Daily Living	Changes in the enhanced activities in daily living. Enhanced activities in daily living will be measured in an instrumental ADL scale at scheduled visits: the Barthel Index that measures the following criteria: chair/bed transfers, ambulation, ambulation/wheelchair, stair climbing, toilet transfers, bowel control, bladder control, bathing, dressing, personal hygiene, and feeding.	12 weeks
Secondary	Time to Closure	This will be the time from Day 0 to the day that 100% or reepithelization without drainage or exudate has occurred. In addition, any wounds/ulcers that have not had complete closure by week 12 the maximum reported closure will be reported, and the data censored at 12 weeks.	12 weeks
Secondary	Incidence of Healing	The proportion of subjects in which complete closure has occurred by Week 12.	12 weeks
