Effect of Amnio-Maxx on the Healing Rate of Chronic Diabetic Foot Ulcers.

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

Effect of Amnio-Maxx on the Healing Rate of Chronic Diabetic Foot Ulcers. (NCT07209475) is a Phase 4 interventional studying Diabetic Foot Ulcer (DFU) and Amnio-Maxx, sponsored by Royal Biologics. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This study will evaluate a cellular, acellular, matrix-like product (CAMP) and Standard of Care (SOC) versus SOC alone in the closure of nonhealing diabetic foot ulcers (DFUs). The study will evaluate Amnio-Maxx® Dual Layer Amnion Patch.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 248 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Diabetic Foot Ulcer (DFU) subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: Potential subjects are required to meet all the following criteria for enrollment into the study and subsequent randomization. 1. The potential subject is 18 years of age or older. At least 50% of the enrolled population must be \> 65 years of age. 2. The potential subject has a history of Type I or Type II Diabetes Mellitus requiring treatment by a physician with either oral medications and/or insulin replacement therapy. 3. Potential subjects have an ulcer characterized by the following: 1. Presence of a diabetic foot ulcer 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. \[NOTE: If two or more DFUs are present with the same grade, the index ulcer is the largest ulcer and the only one evaluated in the study. Index ulcer must be more than 5 cm distant apart.\] 2. A 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. 4. Objectively, less than 20% healing in the two-week screening period prior to randomization. 5. Study ulcer is a minimum of 1.0cm2 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 willing to sign a consent form. 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. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

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.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
