Omeza Combination Therapy for the Management and Treatment of Chronic Cutaneous Wounds/Ulcers of Multiple Etiologies
A Clinical Study to Evaluate the Omeza Combination Therapy for the Management and Treatment of Chronic Cutaneous Wounds/Ulcers of Multiple Etiologies
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:
