There is an indication that enrolement is not going as well as could be. I think their problem could be to convince doctors to let thier applicable patients do this trial, hence, the network that Hee signed up with.
Whatever PR they are doing should be starting to work and once the first lot of patients is sorted and started, the word will get around (as it tends to with these types of things) and more people will be aware of the product and may want to try it.
