Brief Summary:
This study is to evaluate the efficacy of Omeza® Lidocaine Lavage, Omeza® Collagen Matrix and Omeza® Skin Protectant used in combination with off-loading devices for the treatment of diabetic foot ulcers.

Condition or disease Intervention/treatment Phase
Diabetic Foot Ulcer Combination Product: Omeza collagen matrix, Omeza lidocaine lavage, Omeza skin protectant Not Applicable

Detailed Description:
The study will have three phases: screening, treatment and healing confirmation. The screening phase is to determine eligibility of subjects and chronicity of the diabetic foot ulcer and will include off-loading. The treatment phase begins with assessment to confirm continued eligibility and if met, subjects will be treated weekly with the Omeza combination therapy and standard of care to continue offloading. At the conclusion of the 4 weekly treatments, healing will be assessed and continued therapy will be at the PI's discretion.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 25 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: Open-label, single arm to evaluate efficacy in chronic, non-healing wounds.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Clinical Study Using Omeza Products in Combination With Standard of Care for the Treatment of Diabetic Foot Ulcers
Estimated Study Start Date : September 2022
Estimated Primary Completion Date : October 2022
Estimated Study Completion Date : December 2022


Arm Intervention/treatment
Experimental: Omeza combination therapy and SOC with total contact cast

Omeza's products were developed to utilize the benefits of essential omega fatty acids to reduce chronic inflammation and disrupt biofilm colonization commonly found in chronic wounds. The Omeza combination treatment under investigation in this study includes two over the counter (OTC) drugs, Omeza® Lidocaine Lavage and Omeza® Skin Protectant, and a 510(K) medical device, Omeza® Collagen Matrix.

In combination with standard of care and total contact cast, the products will be applied on a weekly basis. There will be a 14-day screening period to assess chronicity from standard of care alone. At that time treatment will be applied weekly for 4 weeks. Further treatment will be at the discretion of the PI to continue for 8 more weeks or until wound closure.

Combination Product: Omeza collagen matrix, Omeza lidocaine lavage, Omeza skin protectant
The three omeza products were designed to be used in combination for the treatment of chronic wounds




Primary Outcome Measures :
  1. Percent area change after 4 weeks of treatment compared to baseline [ Time Frame: 6 weeks ]
    After a 2 week screening phase with standard of care and total contact casting, the wound will be measured and assessed by Tissue Analytics platform. At each treatment visit the change in the wound size and healing status will be assessed. After 4 weeks of treatment the change in wound size will be compared to baseline measurement from treatment visit 1 and the percent area reduction (PAR) recorded.

  2. Incidence in wound closure by week 12 of treatment [ Time Frame: 14 weeks ]
    Treatment will continue and measurements recorded by Tissue Analytics platform until wound closure or up to 12 weeks of treatment.


Secondary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: 14 weeks ]
    Safety of the products used in combination will be assessed by the PI and assesses throughout treatment for adverse events or reactions to the products.

  2. Change in subject's perception of pain at baseline and weekly throughout treatment [ Time Frame: 14 weeks ]
    Subjects will be required to assess ulcer pain at baseline and at each treatment visit by a questionnaire assessing pain on a numerical scale

  3. Increase in physical function and ambulation [ Time Frame: 14 weeks ]
    Subjects will be asked to complete a questionnaire to assess physical function and ambulation status at baseline and at each treatment visit.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Subject is at least 18 years old and female subjects are not pregnant
  • Subject is diagnosed as having Type 1 or Type 2 diabetes
  • Presence of a DFU, Wagner 1 or 2, extending at least through the dermis, provided it is below the level of the medial or lateral malleolus
  • Target wound will be located on the foot or ankle and will be the largest ulcer if two or more DFUs are present with the same Wagner grade and will be the only one evaluated in the study. If other ulcerations are present on the same foot, they must be more than 2cm distant from the target wound.
  • Study ulcer has been present for at least 1 month and less than or equal to 12 months as of the date the subject signs consent for study
  • Study ulcer size is a minimum of 1.0 cm2 and a maximum of 100.0 cm2
  • Study ulcer may have characteristics that include yellow/white slough with or without fibrous/scar tissue and/or non-viable tissue, but not mandatory
  • Subject understands and is willing to participate in the clinical study including offloading prior to study start, participate in the informed consent process, and can comply with weekly visits and the follow-up regimen
  • Willing and able to comply with study procedures, including study visits and study dressing regimens
  • Subject has read and signed the IRB-approved Informed Consent Form before screening procedures are undertaken

Exclusion Criteria:

  • Study ulcer deemed by the Investigator to be caused by a medical condition other than Diabetes
  • Study ulcer exhibits clinical signs and symptoms of infection, as evidenced by tissue necrosis, redness, pain, and/or purulent drainage and/or receiving systemic antibiotics for the treatment of such
  • Study ulcer is treated with a topical antibiotic during the screening phase
  • Study ulcer requires enzymatic debridement during the study
  • Study ulcer is less than 2.0 cm2 or greater than 100.0cm2
  • Study ulcer has been treated with tissue engineered material (e.g., Apligraf® or Dermagraft®) or other scaffold materials (e.g., Oasis, PuraPly AM or Matristem) within the last 30 days
