MiMedx (NASDAQ: MDXG), the leading biopharmaceutical company developing and marketing regenerative and therapeutic biologics utilizing human placental tissue allografts with patent-protected processes for multiple sectors of healthcare, today announced that the first patients have been randomized and enrolled in the Company's Phase 3 Investigational New Drug (IND) clinical trial for MiMedx's micronized amniotic tissue, AmnioFix® Injectable, in the treatment of Achilles Tendonitis.

The Phase 3 Achilles Tendonitis clinical trial is studying MiMedx's AmnioFix® Injectable in a prospective, double blinded, randomized controlled trial of the Micronized dHACM (dehydrated Human Amnion Chorion Membrane) Injection as compared to saline placebo injection.

The design of the Phase 3 Achilles Tendonitis study will include approximately 158 patients. The primary efficacy endpoint of this study will be the change in Visual Analog Scale (VAS) score for patients between baseline and Day 90 between the AmnioFix Injectable group versus placebo-treated group. The primary safety endpoint will be the proportion of product-related adverse events, serious adverse events, and unanticipated adverse events during the first twelve months post injection in the AmnioFix Injectable group versus the placebo-treated group.

Parker H. "Pete" Petit, Chairman and CEO, said, "We are pleased to enroll our first patients in this important Phase 3 IND study in the Orthopedic/Sports Medicine area. Clearly, there is an unmet need in the market for this type of treatment, and we believe the efficacy and safety profile of AmnioFix Injectable meets that need. Available treatments such as corticosteroids or platelet rich plasma have not been consistently shown to be effective as a first-line therapy for this condition. This is our second Phase 3 clinical trial that has commenced patient enrollment. Yesterday, we announced the start of patient enrollment on our Phase 3 Plantar Fasciitis clinical trial."

Bill Taylor, President and COO, said, "Following the completion of this Achilles Tendonitis Phase 3 trial and the Company's other ongoing Phase 3 trial for the use of AmnioFix Injectable in the treatment of Plantar Fasciitis, MiMedx plans to submit a Biologic License Application (BLA) to the FDA for tendonitis. With the ineffectiveness of available treatments, the lack of other safe and effective treatment options, and the high risks associated with pain management by opioids, the unmet need for a safe and effective first-line regenerative medicine therapy to treat pain and function symptoms for tendonitis, such as AmnioFix Injectable, is clear. Beginning Phase 3 enrollment so close together in our Achilles Tendonitis and our Plantar Fasciitis studies, should also allow both trials to complete around the same time and fit very well into our timing for the BLA submission for an overall tendonitis indication."
