Clinical Trial Summary

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

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 Derm-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.

• Subjects with one of the following wounds: Diabetic foot ulcer present for greater than 4 weeks (documented in the medical record) but less than 12 months duration if being treated with active SOC.

• Objectively, less than 20% healing in the two-week run-in period prior to randomization

• Study ulcer is a minimum of 0.5 cm2 and a maximum of 25 cm2 at first treatment visit

• The subject is able and willing to follow the protocol requirements

• Subject has signed informed consent

• 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.

• 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

• Subject is unable to comply with offloading device

• Subject has ulcers that are completely necrotic or fibrotic tissue

• Subject has major uncontrolled medical disorders such as serious cardiovascular, renal, liver or pulmonary disease, lupus, palliative care or sickle cell anemia.

• Subject currently being treated for an active malignant disease or subjects with history of malignancy within the wound.

• The Subject has other concurrent conditions that in the opinion of the Investigator may compromise subject safety

• Known contraindications to acellular dermal matrices

• Known allergies to any of the Derm-Maxx components

• Concurrent participation in another clinical trial that involves an investigational drug or device that would interfere with this study.

• Index ulcer has reduced in area by 20% or more after 2 weeks of standard of care from the first screening visit (S1) to the TV1/randomization visit.

• Subject is pregnant or breast feeding.

• 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.

• 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.

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

• Known HbA1C >12%

• An ulcer that has visible signs of improvement in the four weeks prior to randomization defined objectively as a 40% reduction in surface area in the four weeks prior to enrollment.

• An ulcer that has healed by more than 20% in the 2 weeks prior to screening:
