MARIETTA, Ga., Aug. 24, 2018 /PRNewswire/ -- MiMedx Group, Inc. (NASDAQ: MDXG), a leading developer and marketer of regenerative and therapeutic biologics, today announced that a new study regarding the use of EpiFix® in the treatment of diabetic foot ulcers (DFUs) has been published in the peer-reviewed journal, International Wound Journal.
The paper is entitled "A Confirmatory Study on the Efficacy of Dehydrated Human Amnion/Chorion Membrane dHACM Allograft in the Management of Diabetic Foot Ulcers: A Prospective, Multicenter, Randomized, Controlled Study of 110 Patients from 14 Wound Clinics." The paper was authored by: William Tettelbach, MD; Shawn Cazzell, DPM; Alexander M. Reyzelman, DPM; Felix Sigal, DPM; Joseph M Caporusso, DPM; and Patrick S. Agnew, DPM. The electronic publication of the article in International Wound Journal can be found at https://onlinelibrary.wiley.com/doi/full/10.1111/iwj.12976.
This multi-center randomized and controlled trial was led by William Tettelbach, MD, principal investigator and former Executive System Medical Director of Wound Care and Hyperbaric Medicine Services for InterMountain Healthcare. Dr. Tettelbach is now Associate Chief Medical Officer for MiMedx, a position that postdated the completion of the study.
Clinical Study Design and Results
The objective of the study was to determine the safety and effectiveness of EpiFix as compared to standard of care (SOC) therapy for the treatment of non-healing DFUs. The primary efficacy endpoint was the incidence of complete wound closure over a 12-week period. Data from 110 patients meeting study inclusion and exclusion criteria were analyzed in the Intent-to-Treat (ITT) cohort. A total of 98 patients completed the study Per Protocol (Per-Protocol cohort).
ITT analysis requires patients to be included even if they did not fully adhere to the protocol. In comparison, in a Per-Protocol analysis, only patients who completed the entire clinical trial according to the protocol are counted towards the final results.
In the current study on an ITT basis, 70% of patients who received weekly EpiFix had complete healing by 12 weeks versus 50% of patients only receiving weekly SOC (EpiFix 70% vs. SOC 50%, p=0.0338).
For patients completing the study per protocol, 81% of those who received weekly EpiFix treatments achieved complete healing by 12 weeks. In comparison, 55% of patients had complete healing in 12 weeks after receiving weekly SOC alone (EpiFix + SOC 81% vs. SOC 55%, p=0.0093).
In the ITT cohort, adjusting for co-variates associated with healing, Cox regression analysis showed patients treated with EpiFix were more than twice as likely to heal completely within 12 weeks as those not receiving EpiFix (HR: 2.15, 95% confidence interval 1.30-3.57, p=0.003).
Mechanism of Action
EpiFix® is a tissue matrix allograft composed of dehydrated human amnion/chorion membrane (dHACM). The Company's published scientific work indicates that MiMedx dHACM retains a diverse array of regulatory proteins including essential growth factors, cytokines and chemokines, which are regulators in inflammation, wound repair and tissue regeneration.
