I would be slightly surprised if they PR unblinding. In other companies the first investors knew a trial was unblinded was when top line results were announced. I really can't say how long it takes between unblind, and top line data, but suspect it may be weeks.
In other companies they've given much the same sort of guidance that NWBO has in essentially giving the status of the trial as being near the point of unblinding. In some cases the trial results were positive, in others negative, but it really didn't matter, the company did it essentially the same way. Once the top line data was revealed, the company generally announced a conference call and webcast to discuss the data and the direction being taken from there.
I would hope that if such a conference call is announced it happens after at least a few hours after the TLD announcement. I say this because on more than one occasion that wasn't the case. A release was put out at 8 a.m. EST, and a webcast was conducted at 9 a.m., as a West Coast investor all was over before I ever got out of bed. As soon as I looked at the quote price I knew something was up, but I was hours behind before I knew what. Companies used to do such things after the market close, but Analysts are largely on East Coast time, and they prefer not staying after the market close, so most such presentations have been scheduled before the open. Admittedly, even when I know a call is coming at 6 a.m. or earlier I'll usually choose not to get up for it, but it's nice to at least have the choice, and on occasion I do set an alarm and listen in live. Hearing the webcast after the fact isn't nearly the same, as by the time I've heard it I've already read the impression of others at cites like this one.
