Clinical Trial Assessing Human Placental Membrane Products and Standard of Care Versus Standard of Care in Nonhealing DFUs and VLUs
Sponsor:

Brief Summary:

The purpose of the study is to evaluate the efficacy of multiple human placental membrane products and Standard of Care (SOC) versus SOC alone in the management of nonhealing diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) over 12 weeks using a modified platform trial design.

Detailed Description:

The C5CAMP trial is a multicenter, prospective, randomized controlled clinical trial to evaluate subjects that meet medical necessity criteria for cellular, acellular, and matrix-like products (CAMPs). The study utilizes a prospective modified platform design to evaluate two separate CAMPs, AM/Single and AM/Double in a single trial. The initial plan is to evaluate two CAMPs; however, the modified platform design permits the inclusion of additional CAMPs. This study will evaluate the clinical utility of multiple CAMPs in the closure of diabetic foot ulcers and venous leg ulcers in subjects in comparison to Standard of Care treatment.

Study Type : INTERVENTIONAL
Estimated Enrollment : 177 participants
Masking : NONE
Masking Description : In addition to the principal investigator's determination of complete closure an independent assessment of the primary endpoint will be performed. Two wound care specialists not associated with the trial ("The Reviewers") will review the digital images of ulcers that have healed. They will review the closed visit and the closure confirmation visit. Deidentified digital images taken with the imaging device will be provided to the reviewers. Two reviewers will assess each photograph and be blinded to the arm in the study.
Primary Purpose : TREATMENT
Official Title : A Multicenter, Prospective, Randomized Controlled Modified Platform Trial Assessing the Efficacy of Human Placental Membrane Products and Standard of Care Versus Standard of Care Alone in the Management of Nonhealing Diabetic Foot Ulcers and Venous Leg Ulcers.
Actual Study Start Date : 2024-12-20
Estimated Primary Completion Date : 2026-11-22
Estimated Study Completion Date : 2027-01-22

    • 8. Subject is taking hydroxyurea.
    • 9. Subject has applied topical steroids to the ulcer surface within one month of initial screening.
    • 10. Subject has a previous partial amputation on the affected foot that results in a deformity that impedes proper offloading of the target ulcer.
    • 11. Subject has a glycated hemoglobin (HbA1c) greater than or equal to 12% within 3 months of the initial screening visit.
    • 12. The surface area of the subject's target ulcer has reduced in size by more than 20% in the 2 weeks prior to the initial screening visit ("historical" run-in period). Imaging Device is not required for measurements taken during the historical run-in period (e.g., calculating surface area using length X width is acceptable).
    • 13. The surface area measurement of the subject's target ulcer decreases by 20% or more during the active 2-week screening phase.
    • 14. Subject has acute Charcot foot, or an inactive Charcot foot, which impedes proper offloading of the target ulcer.
