MediWound Announces Positive Topline Results From Its U.S. Phase 2 Trial of EscharEx for

Debridement of Chronic Wounds

Primary Endpoint Met with Highly Statistically Significant Results

 No Observed Safety Issues

Final Data Readout Expected in Second Quarter of 2022

 

YAVNE, Israel, January 24, 2022 -- MediWound Ltd. (Nasdaq: MDWD), a fully-integrated biopharmaceutical company focused on next-generation biotherapeutic solutions for tissue repair and regeneration, today announced positive topline results from its U.S. Phase 2 clinical study of EscharEx^® for the debridement of venous leg ulcers (VLUs). The study met its primary endpoint, demonstrating that patients treated with EscharEx had a statistically significant higher incidence of complete debridement compared to the gel vehicle, with a p-value of 0.004.

The study randomized 120 patients, of which 119 patients were treated by either EscharEx (n=46), a gel vehicle (n=43), or a non-surgical standard-of-care consisting of either enzymatic or autolytic debridement (n=30). The study met its primary endpoint with high degree of statistical significance. Patients treated with EscharEx demonstrated a higher incidence of complete debridement during the 14-day measurement period within up to 8 applications compared to patients treated with gel vehicle (EscharEx: 63% (29/46) vs. gel vehicle: 30% (13/43), p-value=0.004). After adjusting for pre-specified covariates ascribed to patient baseline characteristics, wound size and age, regions, and sites, EscharEx efficacy superiority remained statistically significant compared to gel vehicle. Incidence of complete debridement of the non-surgical standard-of-care arm, during the same 14-day measurement period, was 13% (4/30).

In addition, the Independent Data Monitoring Committee reviewed the data of all patients treated and no safety concerns were identified in the study population. EscharEx was well-tolerated and overall safety was comparable between the arms. No differences were found in reported adverse events and no serious adverse event was related to study treatment. Patient baseline characteristics were comparable across all study arms.

“We are excited to report these robust topline results from our U.S. Phase 2 clinical study, which corroborate the results of our prior Phase 2 study. The primary endpoint efficacy data are highly encouraging and further reinforce our belief that EscharEx has the potential to become a best-in-class non-surgical debridement option for the millions of patients suffering from chronic wounds,” said Sharon Malka, Chief Executive Officer of MediWound. “Chronic wound care is a billion-dollar market opportunity, and we believe EscharEx is well-positioned to potentially be a meaningful part of that market. We look forward to reviewing the full data set in the coming months with the goal of advancing this exciting program into pivotal Phase 3 clinical trials.”

Patient follow-up is ongoing and additional data, including secondary and exploratory endpoints as well as additional safety measurements, which will allow further evaluation of clinical benefits, is expected in the second quarter of 2022. MediWound currently expects to request an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (the “FDA”) in the second half of 2022, to discuss program results and the potential Phase 3 pivotal plan for EscharEx.

Dr. Robert Snyder, Chief Medical Director of the EscharEx program added, “I continue to be impressed by the clinical data generated by the EscharEx trials. There is a great unmet medical need to effectively debride chronic wounds in a non-surgical and prompt manner, as debriding the wound is a critical first step for consequent wound management. I believe EscharEx holds great potential to be a significant and welcome addition to our treatment armamentarium for chronic wounds. We thank our partners, the investigative staff, and especially the patients and families for their commitment and perseverance in completing the study in the face of all the challenges posed by the pandemic.”

Specifically, this press release contains forward-looking statements concerning the anticipated progress, development, study design, expected data timing, objectives anticipated timelines, expectations and commercial potential of our products and product candidates, including EscharEx. Among the factors that may cause results to be materially different from those stated herein are the inherent uncertainties associated with the uncertain, lengthy and expensive nature of the product development process; the timing and conduct of our studies of our products and product candidates, including the timing, progress and results of current and future clinical studies, and our research and development programs; the approval of regulatory submission by the European Medicines Agency or by any other regulatory authority, our ability to obtain marketing approval of our products and product candidates in the U.S. or other markets; the clinical utility, potential advantages and timing or likelihood of regulatory filings and approvals of our products and products; our expectations regarding future growth, including our ability to develop new products; risks related to our contracts with BARDA; market acceptance of our products and product candidates; our ability to maintain adequate protection of our intellectual property; competition risks; the need for additional financing; the impact of government laws and regulations and the impact of the COVID-19 pandemic.  For example, we are unable to predict how the pandemic will affect the overall healthcare infrastructure, including the ability to recruit patients, the ability to conduct the studies in medical sites and the pace with which governmental agencies, such as the FDA, will review and approve regulatory submissions. Additional government-imposed quarantines and requirements to “shelter at home” or other incremental mitigation efforts also may impact our ability to source supplies for our operations or our ability or capacity to manufacture, sell and support the use of our products and product candidates in the future.
