Clinical translation limit
Leech hyaluronidase is mechanistically related to (but distinct from) the human recombinant hyaluronidase product Hylenex, which is an FDA-approved separate pharmaceutical with its own evidence base. Leech-derived hyaluronidase has no independent FDA approval and its 'spreading factor' role is preclinical/mechanistic only.
