Amnioexcel® Evidence

Findings from a multicenter study comparing AMNIOEXCEL® Amniotic Allograft Membrane against standard-of-care for treating diabetic foot ulcers has been published in the WOUNDS Journal. Data from this new study shows 46% (‡ Per Protocol population) of subjects treated with AMNIOEXCEL® plus standard-of-care achieved complete wound closure by six weeks, while 0% of subjects treated with standard-of-care alone achieved complete wound closure.

A Prospective, Randomized, Multicenter and Controlled Evaluation of the Use of Dehydrated Amniotic Membrane Allograft (DAMA - AMNIOEXCEL®) compared to Standard of Care for the Closure of Chronic Diabetic Foot Ulcers.

Amnioexcel RCT Graph #NCT02209051

This prospective, multicenter, randomized, controlled clinical trial (RCT) with standardized ulcer care and off-loading incorporated a 2-week run-in period. Despite a short 6-week study period, ANIOEXCEL® + SOC achieved significantly greater (p=0.008) ulcer closure rates over SOC alone.

WOUNDS, March 2016

In this trial:

  • Stratified randomization yielded a statistically balanced demographic and wound characteristic distribution between groups
  • Endpoint of complete ulcer closure objectively adjudicated with photographs and ulcer tracings
  • Comparable adverse event profile between groups
  • Both the Intent To Treat (all randomized subjects) and the Per Protocol (all completing the study) populations demonstrated statistically significantly greater ulcer closure rates with the addition of AMNIOEXCEL® to the standard of care regimen.

AMNIOEXCEL® Amniotic Allograft Membrane is a novel human placental-based tissue product. The membrane forms a protective covering over the wound while providing the key components found in human amnion including an intact ECM (extracellular matrix), cytokines and other growth factors. The dehydrated membrane is easy to store and use and helps provide the optimal environment to repair, reconstruct and replace wound tissue.
