MediWound Announces Positive Top-Line Results from Its Pivotal Phase 3 Study (DETECT) in NexoBrid® for Eschar Removal of Severe Thermal BurnsMet Primary and All Secondary Endpoints with Statistically Significant Results Compared with Control Group Conference call with MediWound management and U.S. key opinion leader begins today, January 22, 2019 at 10:00 a.m. Eastern time YAVNE, Israel, Jan. 22, 2019 (GLOBE NEWSWIRE) -- MediWound Ltd. (Nasdaq: MDWD), a fully-integrated biopharmaceutical company bringing innovative therapies to address unmet needs in severe burn and wound management, today announced that it has met its primary and all secondary endpoints in its pivotal U.S. Phase 3 clinical study (DETECT) with NexoBrid to treat patients with deep partial thickness (DPT) and full thickness (FT) thermal burns intended for submission for Biological License Application (BLA) from U.S. Food and Drug Administration (FDA). “We are thrilled to announce these robust positive results across all endpoints, which corroborate our previous positive EU Phase 3 clinical study results and clearly demonstrate the significant beneficial impact NexoBrid has on patients’ lives,” said Gal Cohen, President and Chief Executive Officer of MediWound. “Our innovative product, NexoBrid, represents a new paradigm in burn care management. These significant results clearly confirm its ability to remove the eschar earlier while significantly reducing patients' surgical burden, two outcomes that are both clinically and pharmacoeconomically important.” NexoBrid Phase 3 Study Design and Objectives Complete eschar removal was the primary endpoint of the study and was tested against the Gel Vehicle control arm. The primary analysis was based on whether complete eschar removal was achieved in all target wounds of a patient. The analysis compared all randomized patients to the NexoBrid arm to all randomized patients to the Gel Vehicle control arm. Secondary endpoints included reduction in the need for surgical eschar removal (surgical burden), earlier eschar removal, and blood loss, which were tested against the SOC control arm. All secondary endpoints were analyzed and compared all patients randomized to the NexoBrid arm to all patients randomized to the SOC control arm. Time to complete wound closure (non-inferiority) and other standard safety measurements were also compared with the SOC control arm. Funding and support for this pivotal U.S. Phase 3 clinical study (DETECT) with NexoBrid is provided by the Biomedical Advanced Research and Development Authority (BARDA), under the Assistant Secretary for Preparedness and Response (ASPR), within the U.S. Department of Health and Human Services (HHS), under ongoing USG Contract No. HHSO100201500035C. Demographics and other baseline characteristics Summary of Study Results
Primary Endpoint Secondary Endpoints Patients treated with NexoBrid demonstrated a significantly lower incidence of surgical eschar removal compared with patients treated with SOC (NexoBrid: 4.0% (3/75) vs. SOC: 72.0% (54/75), p<0.00012). Patients treated with NexoBrid demonstrated a significantly shorter time to achieve complete eschar removal compared with patients treated with SOC (median time - NexoBrid: 1.0 days vs. SOC: 3.8 days, p<0.00013). Patients treated with NexoBrid incurred significantly lower blood loss during the eschar removal procedure compared with patients treated with SOC (mean volume – NexoBrid: 14.2 ml vs. SOC: 814.5 ml, p<0.00014). Safety The overall safety profile of NexoBrid in the study is good, and consistent with the safety data known from previous studies. Long-Term Safety Follow up Biological License Application (BLA) Submission Plan “This Phase 3 study is one of the most comprehensive randomized controlled studies ever conducted in burn care, and we are very pleased to see such compelling results,” stated Prof. Lior Rosenberg, M.D., Chief Medical Technology Officer of MediWound. “The ability to promptly and effectively remove the eschar while significantly reducing surgical burden on patients, as well as on healthcare systems, can play a major role in mass casualty events where surgical capacity is limited. We would like to take this opportunity to thank BARDA for their overall support for this project.” Stephen T. Wills, MediWound's Chairman added, “We thank all of the Principal Investigators, their teams, and our management and team for their tireless work and endless commitment in an effort to advance burn care. Based on these highly compelling top-line phase 3 results, it is gratifying to know that NexoBrid is one step closer to being available to help burn victims in the U.S., and we look forward to submitting a BLA in the second half of 2019, subject to FDA concurrence.” Conference Call A replay of the call will be accessible two hours after its completion through February 05, 2019 by dialing 844-512-2921 (in the U.S.) or 412-317-6671 (outside the U.S.) and entering passcode 3700005.

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®, received marketing authorization from the European Medicines Agency as well as the Israeli, Argentinian, South-Korean and Russian Ministries of Health, for removal of dead or damaged tissue, known as eschar, in adults with deep partial and full-thickness thermal burns. NexoBrid® represents a new paradigm in burn care management, and clinical trials have demonstrated, with statistical significance, its ability to non-surgically and rapidly remove the eschar earlier and, without harming viable tissues. MediWound's second innovative product, EscharEx® is a topical biological drug being developed for debridement of chronic and other hard-to-heal wounds and is complementary to the large number of existing wound healing products, which require a clean wound bed in order to heal the wound. EscharEx® contains the same proteolytic enzyme technology as NexoBrid®, and benefits from the wealth of existing development data on NexoBrid®. In two Phase 2 studies, EscharEx® has demonstrated safety and efficacy in the debridement of chronic and other hard-to-heal wounds, within a few daily applications.
