is this a problem for tis?

Followed the TIS story for a long time (and liked it), but must admit I'm not a holder anymore and haven't followed the company for at least 12 months.

I saw this announcement by AVH today, and my first thought was this is a better result than what TIS produces. (88% of patients healed of cronic leg ulcers within 28 days).

Not trying to downramp, but was wondering if some knowledgable posters could fill in the gaps.

The AVH announcement is here....

Many thanks.
