Multi-Center Comparative Study Of MiMedx EpiFix® And Organogenesis Apligraf® Determines EpiFix Has Considerably Higher Rates Of Complete Healing And Significantly Faster Time To Heal

MiMedx Group, Inc. (NASDAQ: MDXG), the leading regenerative medicine company utilizing human amniotic tissue and patent-protected processes to develop and market advanced products and therapies for the Wound Care, Surgical, Orthopedic, Spinal, Sports Medicine, Ophthalmic and Dental sectors of healthcare, announced that its latest peer-reviewed clinical study has been accepted for publication in the International Wound Journal.

The highlights of the study, "A Prospective, Randomized, Controlled, Multi-Centre Comparative Effectiveness Study of Healing Using Dehydrated Human Amnion/Chorion Membrane Allograft, Bioengineered Skin Substitute, or Standard of Care for Treatment of Chronic Diabetic Lower Extremity Ulcers," include:

  • After 4 weeks, 85% of EpiFix® patients achieved complete healing compared to only 35% of Apligraf® patients.
  • After 6 weeks, 95% of EpiFix® patients achieved complete healing compared to only 45% of Apligraf® patients.
  • Median time to healing with EpiFix® was 13 days compared to 49 days with Apligraf®.
  • Mean number of EpiFix® grafts used was 2.51 at an average cost of $1,669, compared to 6.2 Apligraf® grafts used at a cost of $9,216.
  • For every square centimeter of EpiFix® wasted, approximately 61.5 centimeters of Apligraf® was wasted.
  • EpiFix® had a superior rate of wound healing and significantly faster rate of wound closure while utilizing 65% fewer grafts and 97.1% fewer square centimeters of graft material.
  • EpiFix® dramatically reduces wastage and costs while achieving superior clinical results.

The prospective multi-center randomized controlled trial (RCT) was conducted at three sites to compare the healing effectiveness of chronic lower extremity diabetic ulcers treated with either weekly applications of Apligraf®, EpiFix®, or standard wound care with collagen-alginate dressing. The electronic publication of the peer-reviewed article is expected to be online in the International Wound Journal by the end of November. The paper was authored by Charles M. Zelen, DPM FACFAS; Lisa Gould, MD PhD; Thomas E. Serena, MD FACS; Marissa J. Carter, PhD MA; Jennifer Keller, DPM; and William W. Li, MD. The hard copy publication is expected to follow in a future issue of the International Wound Journal.

Parker H. Petit, Chairman and CEO, said, "The comparative study established that EpiFix®, our PURION® Processed dehydrated human amnion/chorion membrane (dHACM) allograft, is superior to Apligraf® in both the rate of wound healing and the speed at which wounds are completely healed. A unique aspect of this RCT was the measurement of the amount of product used and its related costs. Not only did EpiFix® achieve superior clinical results, but the study also clearly demonstrated the dramatic cost savings of EpiFix® over Apligraf®. MiMedx has championed the cause to eliminate the excessive wastage that has previously plagued our sector of the healthcare industry. This study confirms the wastage and excessive expense that are caused when size appropriate grafts are not made available to the practicing physicians."

It is expected that some wastage will occur when grafts are trimmed to fit the contours of a wound. The multiple sizes of EpiFix® result in smaller grafts required as a wound decreases in size and less product wastage compared with Apligraf® where each week a 44 square centimeter graft is trimmed to fit the wound regardless of wound size, which, in some cases, results in the majority of the product being discarded." A number of dramatic examples of this wastage were evidenced in the RCT. For every square centimeter of EpiFix® wasted, approximately 61.5 square centimeters of Apligraf® were wasted. Patients treated with EpiFix® utilized 65% fewer grafts and 97% fewer square centimeters of graft material. For the patients treated with EpiFix®, the mean number of grafts used and graft cost per patient were 2.15 grafts at a cost of $1,669, as compared to 6.2 grafts at a cost of $9,216 for patients treated with Apligraf®. The comparative savings based on the average sales price of the products was determined in the study to be 81.9% for those patients treated with EpiFix® compared to Apligraf®,"added Mr. Pete Petit.

Bill Taylor, President and COO, stated, "This study is the first multi-center randomized comparative effectiveness study examining side by side the performance, outcomes, wastage and cost of two generally available advanced wound care products as a treatment for chronic lower extremity diabetic ulcers. We strongly support comparative research as it offers an opportunity for improved clinical outcomes and quality by providing better information on how products perform. This approach is a key ingredient to reducing future health care costs."

"This study has shown that diabetic lower extremity ulcers treated with EpiFix® had significantly greater rates of complete healing and more rapid time to healing than wounds treated with Apligraf®. In addition, EpiFix® was found to be extremely more cost effective than Apligraf®," concluded Taylor.
