I think the therapies are those we mentioned. I have to say that if you do not regard the geographic issue, which I'm not playing down—it's a very serious one—our clinicians are actually completely in tune with international groups. I don't think we would be concerned any more that there's something being tried elsewhere that could not be tried in Canada.
The problem is one of limitations of funding for the clinical centres, because if we could be running things in parallel, that would be a wonderful thing. Right now, financially, it's not possible.
I'm sorry, what was the second half?
