Exhibit 99.1
MediWound Announces Positive Results from its U.S. Phase 2 Pharmacology Study of
EscharEx for Debridement of Lower Leg Ulcers

EscharEx Showed Safe, Effective and Rapid Debridement in VLUs and DFUs
 Data Demonstrates EscharEx Reduced Wound Size, Biofilm and Bacterial Burden

YAVNE, Israel, July 7, 2022 -- MediWound Ltd. (Nasdaq: MDWD) (the “Company”), a fully-integrated biopharmaceutical company focused on next-generation biotherapeutic solutions for tissue repair and regeneration, today announced positive results from its U.S. prospective, open-label, single-arm, Phase 2 pharmacology clinical study of EscharEx® for the debridement of lower leg ulcers.

The study was designed to evaluate the clinical performance, safety and pharmacology effect of EscharEx in debridement of venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). Seventy percent of patients achieved complete debridement during the course of treatment within up to 8 applications. On average, complete debridement was achieved after 3.9 applications of EscharEx. Additionally, an average reduction of 35% in wound size was achieved by the end of the 2-week follow-up period. In all patients that were positive for biofilm at baseline, the biofilm was reduced substantially to single individual microorganisms or completely removed by the end of treatment. Seven patients had positive red fluorescence (indicative of bacteria) at baseline and average red fluorescence was reduced from 1.69 cm2 pre-treatment to 0.60 cm2 post treatment. Biomarker analysis from wound fluid is on-going and safety data shows that EscharEx is safe and well-tolerated.

“The data from our pharmacology study corroborates the results of our previous Phase 2 studies, and clearly supports EscharEx as a potential rapid and effective, non-surgical debriding agent,” said Ofer Gonen, Chief Executive Officer of MediWound. “We are encouraged by the accumulated clinical data and believe that EscharEx, with its attractive product profile, has the potential to become a best-in-class non-surgical debridement option for the millions of patients suffering from chronic wounds.”

Dr. Robert Snyder, Chief Medical Director of EscharEx program added, “We are excited to see the data showing that EscharEx could effectively debride wounds while disrupting biofilm and lowering bacterial load. There is wide consensus among clinicians that infection and microbial biofilm impedes the healing process and prolongs wound healing. We thank our partners, investigative staff, and especially the patients and their families for their commitment in completing the study.”

Study Design
The U.S. phase 2 pharmacology study was a prospective, open label, single-arm study, being conducted at three U.S. clinical sites. The study evaluated the clinical performance, safety, and pharmacology effect of EscharEx in the debridement of lower leg ulcers (VLUs and DFUs). The study evaluated the safety and efficacy of debridement as measured by incidence of, and time to complete debridement. In addition, the study evaluated the pharmacological effects of EscharEx as measured by the changes from baseline to end of treatment period in (1) wound biofilm presence in wound biopsies, (2) bacterial burden measured by MolecuLight® fluorescence images, and (3) biomarkers of wound healing and inflammation in wound fluid.

Twelve patients with either DFUs or VLUs were enrolled in the study. Patients were treated with up to eight daily applications of EscharEx and then continued follow-up for 2 weeks. Punch biopsies and wound fluids were collected prior to the first, and after the last treatment. Biofilm presence was analyzed from wound biopsies. Wound fluids were analyzed to evaluate biomarkers of wound healing and inflammation, i.e., MMPs, cytokines, chemokines, growth factors and HNE. Fluorescent imaging was used during treatment to measure wound size and bacterial load. Fluorescent imaging was also utilized to identify the highest fluorescence area to obtain the biopsy. EscharEx demonstrated safe and effective debridement with a few daily applications. In addition, evaluation of wounds’ tissue samples (biopsies) and fluorescence images, indicated reduction of wound area, biofilm and bacterial bioburden following the treatment with EscharEx.

About Biofilm1
Biofilm is created through the attachment of bacteria to elements in the extracellular polymeric substances (EPS). The EPS, which is 50% to 90% of the total biofilm organic matter, is comprised of dead host tissue, microorganisms’ secretions, proteins, nucleic acids, lipids, and polysaccharides. Biofilm has been reported to interfere with normal wound healing, apparently by ‘locking’ the wound bed into a chronic inflammatory state that leads to elevated levels of tissue-degrading proteases and reactive oxygen species which damage cells and molecules needed for healing. A large percentage of bacteria in biofilm communities are metabolically dormant, and low metabolic rates make antibiotics ineffective. The EPS substances and their interactions are targets for therapeutic biofilm elimination.
Bacterial biofilm has been shown to prolong the inflammatory process, which is detrimental to wound healing because of the degradation of the growth factors required for cellular proliferation and migration necessary for wound healing.

About EscharEx
EscharEx is a bioactive therapy for debridement of chronic and other hard-to-heal wounds in advanced stages of clinical development. Designed for the outpatient setting, EscharEx is an easy-to-use concentrate of proteolytic enzymes enriched in bromelain for topical daily applications.
EscharEx was well-tolerated and demonstrated safety and efficacy in the debridement of various chronic and other hard-to-heal wounds with only few daily applications in several Phase 2 trials. EscharEx’s mechanism of action is mediated by the proteolytic enzymes that cleave and remove the necrotic tissue and prepare the wound bed for healing.
About MediWound Ltd.
MediWound is a biopharmaceutical company that develops, manufactures, and commercializes novel, cost effective, bio-therapeutic solutions for tissue repair and regeneration. Our strategy leverages our enzymatic technology platform, focused on next-generation bioactive therapies for burn care, wound care and tissue repair.
NexoBrid®, our commercial orphan biological product for non-surgical eschar removal of deep-partial and full-thickness thermal burns, is a bromelain-based biological product containing a sterile mixture of proteolytic enzymes that selectively removes burn eschar within four hours without harming surrounding viable tissue. NexoBrid is currently marketed in the European Union and other international markets and is at registration-stage with the Food and Drug Administration (FDA). NexoBrid is supported by the U.S. Biomedical Advanced Research and Development Authority (BARDA).
