We report the first clinical evaluation of a new enzymatic wound debridement product containing tarumase in venous leg ulcer patients. As a first-in-human study, this was a prospective, open-label, multi-centre, dose escalation study across five dose cohorts and involving a total of 43 patients treated three times weekly for up to 4 weeks (12 applications). The primary and secondary endpoints of the study were to assess the systemic safety, local tolerability, and early proof of concept both for wound debridement and healing. Results indicated that the tarumase enzyme was well tolerated when applied topically to wounds, with no indications of systemic absorption, no evidence of antibody generation, and no systemic effects on coagulation pathways.
