MediWound Initiates U.S. Phase 2 Adaptive Design Study of EscharEx® for Treatment of Venous Leg Ulcers

YAVNE, Israel, Dec. 03, 2019 (GLOBE NEWSWIRE) -- MediWound Ltd. (the “Company”) (Nasdaq: MDWD), a fully-integrated biopharmaceutical company bringing innovative therapies to address unmet needs in severe burn and wound management, today announced the initiation of patient treatment in its U.S. Phase 2 adaptive design clinical study of EscharEx, a topical biologic drug candidate designed to enzymatically debride chronic wounds, for the treatment of venous leg ulcers (VLU’s).  The trial is designed to assess safety and efficacy of EscharEx compared to gel vehicle (placebo control) and non-surgical standard-of-care (either enzymatic or autolytic debridement), and includes a pre-defined interim assessment anticipated by the end of 2020.

“We are thrilled to initiate this U.S. Phase 2 adaptive design study of EscharEx, that is built on extensive prior research, including the positive data from the completed Phase 2 study of the first-generation EscharEx,” said Sharon Malka, Chief Executive Officer of MediWound. “The study enables the comparison of EscharEx to placebo control, as well as a head-to-head comparison with the current non-surgical standard of care in the U.S.”

Mr. Malka continued, “We believe EscharEx is a game-changer, addressing a significant unmet medical need for patients affected by chronic wounds with a sizable market opportunity and commercial validation for enzymatic debridement. We are encouraged by the strong interest expressed in the clinical community for participating in this study, and we look forward to working closely with physicians and patients as we advance this exciting development program.”

The multicenter, prospective, randomized, placebo-controlled, adaptive design study, evaluating the safety and efficacy of EscharEx in debridement of VLU’s. The study is expected to enroll 174 patients at approximately 25 clinical sites, primarily in the U.S. Study participants will be randomized to either EscharEx, placebo control or non-surgical standard-of-care of either Santyl or Hydrogel, at a ratio of 1:1:1, with a three month follow-up. The study includes an interim assessment for futility and potential sample size adjustment once approximately 50 percent of patients complete treatment. The primary endpoint is incidence of complete debridement compared to gel vehicle placebo control. Secondary endpoints include time to achieve complete debridement, reduction of pain, reduction of wound area, granulation tissue and quality of life. Incidence and time to achieve wound closure will be assessed as safety measurements.

About EscharEx

EscharEx is a topically administered biological drug candidate that enzymatically debrides chronic and other hard-to-heal wounds, using the same proteolytic enzyme technology as NexoBrid. EscharEx’s advanced formulation has been designed in accordance with current treatment workflow and reimbursement programs to provide a non-surgical, easy-to-use, potent therapy for once-a-day application to better address the unmet medical need for a non-surgical rapid and effective product, particularly in the outpatient setting.



In the recently completed Phase 2 study of the first-generation EscharEx formulation, EscharEx demonstrated safety and efficacy in the debridement of various chronic and other hard-to-heal wounds. EscharEx achieved statistically significant higher incidence of complete eschar removal and demonstrated a shorter time to achieve complete debridement compared to gel vehicle.

About MediWound Ltd.

MediWound is a fully-integrated biopharmaceutical company focused on developing, manufacturing and commercializing novel therapeutics based on its patented proteolytic enzyme technology to address unmet needs in the fields of severe burns, chronic and other hard-to-heal wounds. MediWound’s first innovative biopharmaceutical product, NexoBrid^® has demonstrated in clinical studies, with statistical significance the ability to non-surgically and rapidly remove the eschar earlier and without harming viable tissue. The product has received marketing authorization from the European Medicines Agency as well as the Israeli, Argentinian, South Korean, Russian and Peruvian Ministries of Health. MediWound's second innovative product, EscharEx^® is a topical biological drug candidate for the debridement of chronic and other hard-to-heal wounds using the same proteolytic enzyme technology as NexoBrid. In two Phase 2 studies, EscharEx has demonstrated safety and efficacy in the debridement of various chronic and other hard-to-heal wounds, within a few daily applications.
