This trial was not conducted on humans, it is years away from that. As it turns out it wasn't even a blind trial in animals, but a very preliminary look at this in the lab. If this turns out to be something useful down the road is a long way from anyone knowing. Funding in this economy for a long shot like this will be hard to get to move it forward. Human clinical trials may or may not ever get funded. Application from those trials to a usable treatment or pharma application all the was through the FDA�. decades perhaps.
