Well, we do know for a fact that 179 patients were enrolled as of 2/6/06, and 294 as of 11/6/06. I'm guessing that the numbers from Dr. Provost's Feb 2006 meeting before CTGTAC in which she discussed the CD54 data for 99 patients, if those 99 did indeed represent an accurate full enrollment figure, were from early Feb 2005. If the 180th event does in fact take place in 2H 2008, perhaps 30% of the patients will have been followed for at least three years.
