MW005 shown to be safe and well-tolerated

Data provide clinical efficacy proof-of-concept based on clearance of target lesions

YAVNE, Israel, I July 10, 2023 I MediWound Ltd. (Nasdaq: MDWD), a fully-integrated biopharmaceutical company focused on next-generation enzymatic therapeutics for tissue repair, today announced positive data from its Phase I/II study to evaluate the safety and efficacy of MW005 in the treatment of low-risk Basal Cell Carcinoma (BCC). The data show MW005 to be safe and well-tolerated, with patients achieving complete clinical and histological clearance of their target lesions.

The Phase I/II study is an open-label, multi-centered, randomized clinical trial designed to evaluate the safety and efficacy of MW005 in patients with BCC. All of the patients enrolled in the study had histologically confirmed superficial or nodular BCC. Enrolled patients received seven topical applications of MW005 once every other day for fourteen days. Eight weeks following the last treatment, all patients underwent a complete excisional biopsy. The excised specimen was subjected to an independent histological clearance examination. The study’s endpoints include safety and tolerability measurements, as well as efficacy assessments, as measured by the proportion of patients who reach clinically and histologically confirmed complete clearance.

Fifteen patients were treated with MW005 and completed the study. Results showed MW005 to be safe and well-tolerated, with a high level of patient compliance. While the primary focus of the trial was on safety and tolerability, it is worth noting that based on clinical assessments, eleven out of fifteen patients achieved complete clearance of their BCCs;   the majority of these patients also had histologically confirmed complete clearance. Data comprising clinical and histological outcomes, supported by extensive patient follow-up, will be featured at an upcoming scientific conference in 2023.

These results corroborate the previous proof-of-concept study published by Prof. Rosenberg et al (Basal Cell Carcinoma Destruction by a Concentrate of Proteolytic Enzymes Enriched in Bromelain: A Preliminary Report; TODJ-15-39, 2021), where seven BCC tumors treated with MW005 were completely removed based on clinical assessment, and none reoccurred over the subsequent 24 months.

“Most low-risk BCCs are treated surgically. There is a clear unmet need for an effective, non-surgical, topically-applied, short duration treatment for low-risk BCC, with a superior tolerability profile, with less severe local skin reactions associated with current topical therapies,” said Dr. Brian Berman, past president of American Dermatological Association, Professor Emeritus, University of Miami, and a lead principal investigator of the Phase I/II study. “These encouraging results from the clinical study of MW005 suggest that we are headed in the right direction and on track for a possible solution.”

Ofer Gonen, CEO of MediWound, said, “These data further validate the potential of MW005 as a significant advancement in cancer treatment. BCC affects two to three million individuals in the U.S. each year, and we believe MW005 may reduce the reliance on expensive and potentially disfiguring surgical procedures in certain cases, thereby improving patient experiences and outcomes.”
