FDA Approves NexoBrid

FDA Approves NexoBrid (anacaulase-bcdb) for the Treatment of Severe Thermal Burns in Adults

YAVNE, Israel, Dec. 29, 2022 (GLOBE NEWSWIRE) -- MediWound Ltd. (Nasdaq: MDWD) (the “Company”), a fully-integrated biopharmaceutical company focused on next-generation biotherapeutic solutions for tissue repair and regeneration, today announced that the U.S. Food and Drug Administration (FDA) has approved NexoBrid® (anacaulase-bcdb) for the removal of eschar in adults with deep partial-thickness and/or full-thickness thermal burns.

“We are pleased and excited that the FDA has approved NexoBrid, an innovative, non-surgical alternative for the treatment of severe burn injuries,” said Ofer Gonen, Chief Executive Officer of MediWound. “We appreciate and thank the burn patients who participated in our trials, the clinical investigators, and our researchers for their commitment and efforts to attain this significant achievement. We also thank our partner, BARDA, for their unwavering support since 2015, and our commercial partner, Vericel, who will launch NexoBrid in the U.S. This U.S. FDA approval of NexoBrid validates our enzymatic technology platform. MediWound will continue to pursue its strategic plans to advance the development of novel therapies for burn care, wound care, and tissue repair; we look forward to an exciting and productive 2023.”

Past President of the American Burn Association, Lucy A. Wibbenmeyer, MD, Clinical Professor of Surgery-Acute Care Surgery, Iowa City, IA added, “NexoBrid enables fast and effective topical treatment for eschar removal in patients with second- and third-degree thermal burns. I believe that NexoBrid could offer a paradigm shift in burn care and has the potential to become a standard of care in this significant market.”

NexoBrid is already approved for use in 43 countries, including the European Union, Japan, India, and other international markets. Vericel Corporation (Nasdaq: VCEL) holds an exclusive license to commercialize NexoBrid in North America. MediWound will receive a $7.5 million milestone payment from Vericel Corporation, triggered by the FDA approval of NexoBrid.

The BLA submission leading to FDA approval covered by a comprehensive battery of pre-clinical studies and 8 clinical studies, including the pivotal Phase 3 U.S. clinical study (DETECT), which evaluated the efficacy and safety of NexoBrid in adult patients with deep partial-thickness and full-thickness thermal burns of 3%-30% of total body surface area (TBSA).

The study met its primary endpoint of incidence of ≥95% eschar removal compared to gel vehicle, as well as all secondary endpoints, including shorter time to eschar removal, lower incidence of surgical eschar removal and lower blood loss compared to surgical and non-surgical standard of care (SOC), including both surgical and non-surgical eschar removal methods, with highly statistically significant results. A safety endpoint of non-inferiority in time to >95% wound closure compared with patients treated with SOC was also achieved. In addition, non-inferiority was established between NexoBrid and SOC in cosmesis and function of burn scars after 12- and 24-month follow-up. Overall, NexoBrid is safe and well tolerated.

NexoBrid can be applied in up to two applications of four hours each. A first application of NexoBrid may be applied to an area of up to 15% body surface area. A second application of NexoBrid may be applied 24 hours later, with a total treated area for both applications of up to 20% TBSA.

NexoBrid development has been supported in part with federal funding from U.S. Biomedical Advanced Research and Development Authority (BARDA), Administration for Strategic Preparedness and Response (ASPR), within the U.S. Department of Health and Human Services (HHS), under ongoing USG Contract number HHSO100201500035C. Contract number HHSO100201500035C provided funding and technical support for the pivotal U.S. Phase 3 clinical study (DETECT) and the marketing approval registration process for NexoBrid. BARDA also established national preparedness and availability of NexoBrid for use in emergency as well as continued to train burn care providers under the expanded access treatment protocol (NEXT) in the U.S. In addition, BARDA has supported the evaluation of NexoBrid in the pediatric population and the BLA is expected to be submitted for FDA approval in 2023. To enable adoption of NexoBrid as an MCM within US healthcare, BARDA has also supported development of the health economic model to evaluate the cost savings impact. It is anticipated to aid realistic assessment of value to promote market integration and establishment of national preparedness in the United States. In 2018, BARDA also initiated evaluation of NexoBrid for debridement after chemical injuries under another contract HHSO100201800023C.

MediWound is a biopharmaceutical company that develops, manufactures, and commercializes novel, cost effective, bio-therapeutic solutions for tissue repair and regeneration. Our strategy is to leverage our enzymatic technology platform, focusing on next-generation therapies for burn care, wound care, and tissue repair.

NexoBrid® is our commercial orphan biological product for early non-surgical eschar removal of deep-partial and full-thickness thermal burns. It 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, Japan, India, and other international markets, and recently received FDA approval for marketing in the U.S. NexoBrid is supported by the US Biomedical Advanced Research and Development Authority (BARDA), Administration for Strategic Preparedness and Response (ASPR), within the U.S. Department of Health and Human Services (HHS).

EscharEx® is based on the same active pharmaceutical ingredient as NexoBrid. It is under development for the debridement of chronic and hard-to-heal wounds. Results from Phase 2 studies show that EscharEx is significantly more effective and faster than SOC or placebo control in debridement of VLUs and DFUs, with a good safety and tolerability profile. MediWound has initiated discussions with the FDA regarding the EscharEx pivotal Phase 3 study design.

MW005 is a topical biological drug under development for the treatment of low-risk Basal Cell Carcinoma (BCC). In a Phase I/II open-label, multicenter, randomized clinical trial conducted in the U.S., MW005 was shown to be safe, well-tolerated, and an effective treatment for BCC with patients demonstrating complete clinical and histological clearance of target lesions.
