MediWound Announces Positive Outcome of Interim Assessment for its EscharEx U.S. Phase 2 Adaptive Design Study
July 28, 2021 at 07:00 AM EDT
Independent Data Monitoring Committee Recommends Continuation of the Study with
No Safety Concerns Identified
Full Study Enrollment Expected by Year-End 2021; Data Readout Expected in the First Half of 2022
YAVNE, Israel, July 28, 2021 (GLOBE NEWSWIRE) -- MediWound Ltd. (Nasdaq: MDWD), a fully-integrated biopharmaceutical company focused on next-generation biotherapeutic solutions for tissue repair and regeneration, today announced a positive outcome from a planned interim sample size re-estimation of its ongoing EscharEx® U.S. phase 2 adaptive design study for the treatment of venous leg ulcers (VLUs), designed to assess the safety and efficacy of EscharEx compared to gel vehicle (placebo control) and non-surgical standard-of-care (either enzymatic or autolytic debridement).
Based on the Independent Data Monitoring Committee’s (IDMC) recommendation, no changes to the original enrollment target of 120 patients is required to maintain the pre-specified statistical power of 80 percent or greater on the study’s primary endpoint of incidence of complete debridement compared with gel vehicle. In addition, the IDMC reviewed the data of all subjects treated and no safety concerns were identified in the study population. The IDMC’s recommendations were based on the results of a pre-specified interim conditional power assessment conducted after approximately two-thirds of the originally targeted of 120 patients completed the debridement treatment.
"We are very pleased with the IDMC's recommendation to continue the EscharEx study as originally planned without modifying the study sample size,” said Sharon Malka, Chief Executive Officer of MediWound. "This interim outcome suggests that EschareEx is safe and tolerable, and increases our confidence that EscharEx may prove to be an effective non-surgical therapy for debridement of chronic wounds. With a clear unmet medical need for a non-surgical rapid and effective debridement agent in the outpatient setting, EscharEx has the potential to improve on the current standard of care and have a meaningful impact on chronic wound management. We remain on track to complete patient enrollment by year-end, with data readout expected in the first half of 2022."
The multicenter, prospective, randomized, placebo-controlled, adaptive design study, evaluating the safety and efficacy of EscharEx in debridement of VLUs. The study is expected to enroll 120 patients at approximately 20 clinical sites, primarily in the U.S. Study participants are randomized to either EscharEx, placebo control or non-surgical standard-of-care of either enzymatic or autolytic debridement, at a ratio of 3:3:2, with a three-month follow-up. The study includes a pre-defined interim assessment for futility and potential sample size adjustment. 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.
EscharEx, our bioactive therapy for debridement of chronic and other hard-to-heal wounds, is a product candidate in advanced stages of clinical development. EscharEx, a concentrate of proteolytic enzymes enriched in bromelain, is an easy-to-use product candidate, for topical daily applications, which designed for the outpatient setting.
In two phase 2 trials, EscharEx was well-tolerated and has demonstrated safety and efficacy in the debridement of various chronic and other hard-to-heal wounds, with only few daily applications. The mechanism of action of EscharEx is mediated by the proteolytic enzymes that cleave and remove the necrotic tissue and prepare the wound bed for healing. EscharEx is an investigational product, currently under a U.S. phase 2 adaptive design study.
