- Publication in Peer-Reviewed Journal Underscores Statistically Significant Difference Seen in Pain and Foot Function Compared to Control Group

- Mean Visual Analog Scale (VAS) Score for Pain Was Reduced by 76% at Three Months in Treatment Group Compared with a 45% Reduction in Control Group

MARIETTA, Ga., Aug. 2, 2018 /PRNewswire/ -- MiMedx Group, Inc. (NASDAQ: MDXG), a leading developer and marketer of regenerative and therapeutic biologics, today announced that the positive pain and foot function results from its Phase 2B clinical trial of micronized dHACM (dehydrated Human Amnion/Chorion Membrane) in the treatment of Plantar Fasciitis have been published in the peer-reviewed journal, Foot & Ankle International. The publication of this data follows the Company's late-March announcement (3/26/18 Positive Pain and Foot Function Results) that it achieved the primary and secondary efficacy endpoints in this Phase 2B study.

The paper entitled "Randomized Controlled Trial of Micronized Dehydrated Human Amnion/Chorion Membrane (dHACM) Injection Compared to Placebo for the Treatment of Plantar Fasciitis," was authored by: Shawn Cazzell, DPM1; Jordan Stewart, DPM2; Patrick S. Agnew, DPM3; John Senatore, DPM4; Jody Walters, DPM5; Douglas Murdoch, DPM6; Alex Reyzelman, DPM7; and Stuart Miller, MD8. The article in Foot & Ankle International can be found online at http://journals.sagepub.com/doi/full/10.1177/1071100718788549.

The Phase 2B prospective, single-blinded, randomized, controlled trial (RCT) studied a single injection of 40 mg of micronized dHACM injection as compared to a single injection of saline (placebo control) in the treatment of Plantar Fasciitis. The trial enrolled and treated 145 patients at 14 study sites.

Stuart Miller, MD, principal investigator of the most recently published clinical trial, said, "We are encouraged by the results of this Phase 2B clinical study, and look forward to the completion of the Phase 3 clinical study, expected in 2019." 

The primary efficacy endpoint was the mean change in VAS score for pain between baseline and the 3-month follow-up visit. The secondary efficacy endpoint was the mean change in Foot Function Index - Revised (FFI-R) score between baseline and 3 months. The baseline VAS and FFI-R scores were similar between groups. At the 3-month follow-up, the mean VAS score was reduced by 76% for patients in the Treatment Group compared with a 45% reduction for the Control Group (p<0.0001), and the mean FFI-R score was reduced by 60% for patients in the Treatment Group, while the Control Group had mean reduction of 40% versus baseline (p=0.0004).

Overall, at the three-month study follow-up visit, 60 (82.2%) patients in the treatment group, and 34 (47.2%) patients in the control group reported at least a 50% reduction in VAS score from baseline (p<0.0001).

Biologics License Application (BLA) Progress

Based on its Phase 2B interim study results, in January 2018 the Company announced that it had initiated the pivotal Phase 3 clinical trial to assess the safety and efficacy of micronized dHACM injection to treat patients with recalcitrant Plantar Fasciitis pain. Top-line results from the Phase 3 study are expected in the second half of 2019. Following the conclusion of this trial, MiMedx currently anticipates filing a Biologics License Application (BLA) with the U.S. Food and Drug Administration (FDA) for micronized dHACM injection to treat Plantar Fasciitis in the second half of 2020. 

"This is a positive step towards a BLA filing and helping patients with painful plantar fasciitis conditions," noted David Coles, Interim Chief Executive Officer.
