Hopefully, Don will clarify this in the webcast. He must have received some guidance from the FDA.

We have to keep in mind, by the way, that the animal experiments in Australia might not have mirrored the clinical situation precisely. For example, did they give the mice the virus first and then the ABL, or the other way round (i.e., pretreatment)? I can't recall. If it was the latter, ABL might take longer to have an effect clinically.
