Read your post and understand it. In fact I agree with it. But parsing my own words I do not believe I said the trial was being extended to reach a certain level of deaths but rather the trial was designed to stop when a certain level was reached. With that level it was felt statistical significance could be determined even if the total number of accruals was smaller than for most P III trials.

Not reaching the level of deaths causes the trial to continue as planned from the start. This is not the same as extending a trial designed to stop when the number of subjects reached a certain level or a certain date was reached, for a new endpoint, total deaths.
