Amnio-Maxx in Patients With Diabetic Foot Ulcers Unresponsive to Standard of Care Treatment Alone

A Randomized Controlled Multicenter Trial, Examining the Effect of Amnio-Maxx on the Healing Rate of Chronic Diabetic Foot Ulcers

This randomized controlled study evaluates the adjuvant use of Amnio-Maxx in patients with diabetic foot ulcers

Study Overview

• Status: Terminated
• Conditions: Diabetic Foot Ulcer
• Intervention / Treatment: Other: Amnio-Maxx

Detailed Description

This is a multicenter randomized open-label clinical study in patients with Wagner grade 1 and 2 DFUs. Diabetic patients presenting with chronic nonhealing ulcers will be screened for eligibility. At least 50% of the eligible population will be drawn from patients ≥ 65 years of age. All patients will complete a 2-week run-in period prior to treatment allocation to Amnio-Maxx and standard of care (SOC) or SOC alone. Patients will be seen at weekly intervals (± 3 days) for the 12 weeks treatment period. If additional dressing changes are required between the scheduled visits, the occurrence of these visits will be recorded. Primary efficacy endpoints include percentage change in ulcer size at 12 weeks along with the proportion of participants achieving complete wound closure. Additionally, pain and safety will be assessed as secondary endpoints.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. Subjects are 18 years of age or older. At least 50% of the enrolled population must be > 65 years of age.
2. Subject history of Type I or Type II Diabetes Mellitus requiring oral glycemic control and/or insulin replacement therapy.

3. Subjects with the following ulcer:

   A. Presence of a DFU Wagner 1 or 2 grade at the first screening visit on any aspect of the foot, provided it is at or below the aspect of the medial malleolus. [NOTE: If two or more DFUs are present with the same grade, the index ulcer is the largest ulcer and the only one evaluated in the study. Index ulcer must be more than 5 cm distant apart.

   B. A DFU is present for greater than 4 weeks (documented in the medical record) but less than 12 months duration if being treated with active SOC.

4. Objectively, less than 20% healing in the two-week screening period prior to randomization.
5. Study ulcer is a minimum of 1.0 cm2 and a maximum of 25 cm2 post-debridement at first treatment visit
6. Index ulcer and/or index ulcer limb may have had prior infection, but infection(s) must be adequately treated and controlled as defined by IDSA Guidelines Grade level 1.
7. The subject is able and willing to follow the protocol requirements.
8. Subject has signed informed consent.
9. Adequate circulation to the affected foot as demonstrated by a dorsum transcutaneous oxygen measurement (TCOM) or a skin perfusion pressure (SPP) measurement of ≥ 30 mmHg; an ABI between 0.7 and ≤ 1.3, or TBI of >6 within 3 months of the first Screening Visit.
10. Negative pregnancy test for females of childbearing potential (e.g., not post- menopausal for at least one year or surgically sterile). Females of childbearing potential must be willing to use acceptable methods of contraception (birth control pills, barriers, or abstinence) starting at Screening and continuing through the duration of their study participation.
11. The index ulcer has been offloaded with protocol defined offloading device throughout the study run-in period for at least 14 days prior to randomization (Run- in period defined as Screening through TV1/Randomization).
12. The index ulcer has a clean base and free of necrotic debris at time of placement of treatment product.

Exclusion Criteria:

1. Subject has a documented life expectancy of < 1 year.
2. Index ulcer has been present for >1 year.
3. Patient does not have adequate 2-week historical data demonstrating < 20% area reduction.
4. Subject is unable to comply with offloading device.
5. Presence of any condition(s) which seriously compromises the subject's ability to complete this study or has a known history of poor adherence to medical treatment.
6. Subject has ulcers that are completely necrotic or fibrotic tissue.
7. Subject has major uncontrolled medical disorders such as serious cardiovascular, renal, liver or pulmonary disease, lupus, palliative care or sickle cell anemia.
8. Subject currently being treated for an active malignant disease or subjects with history of malignancy within the ulcer.
9. The Subject has other concurrent conditions that in the opinion of the Principal Investigator may compromise subject safety.
10. Known contraindications to amniotic tissue membranes or known allergies to any of the Amnio-Maxx components.
11. Concurrent participation in another clinical trial that involves an investigational drug or device that would interfere with this study.
12. Index ulcer has reduced in area by 20% or more after 2 weeks of SOC from the first screening visit (S1) to the TV1/randomization visit.
13. Subject is pregnant or breastfeeding.
14. 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 30 days prior to randomization visit or who receive such medications during the screening period, or who are anticipated to require such medications during the course of the study.
15. 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 last 30 days preceding the first treatment visit.
16. Affected extremity requiring hyperbaric oxygen during the trial or within 2 weeks of screening treatment visit 1.
17. Presence of diabetes with poor metabolic control as documented with an HbA1c ≥12.0 within 30 days of randomization (TV1).
18. Index ulcer and/or index limb with presence of, gangrene or unstable ischemia at screening (SV1).
19. Revascularization surgery on the lower extremity on which the index ulcer is located within 30 days of Screening Visit (SV1).
20. Index ulcer in the opinion of the Principal Investigator, is suspicious for cancer and should undergo an ulcer biopsy to rule out a neoplasm of the ulcer.
21. Any clinically significant finding, in the judgment of the Principal Investigator, that would place the subject at health risk, impact the study, or affect the completion of the study.
