First clinical evaluation of the safety and efficacy of tarumase for the debridement of venous leg ulcers.

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.

Preliminary evidence supporting a new enzymatic debridement product for use in chronic wounds.

A new recombinant proteolytic enzyme, isolated from maggot saliva, with fibrinolytic action has been investigated through a series of non-clinical toxicology and in-vitro/in-vivo pharmacology studies to explore its potential safety and efficacy as an enzymatic debridement agent for use in chronic wounds. Studies indicate that the enzyme has a good safety profile. When locally administered, it is not detrimental to wound healing, is non-sensitising and is rapidly inactivated in the systemic circulation.
