MolBiol, ultimately we have a Schrodinger's cat problem here. Until we get the news and we know one way or the other the most accurate thing we can say is that there is roughly 50/50 chance of a positive outcome. However,I am convinced of a few things that lead me to favor a positive outcome. Keep in mind that I have no information other than that publicly available and this is solely my opinion as a John Q. Nobody.
1. All trail data to date that I have been able to uncover for various incarnations of DCVax has been very positive. Furthermore, while my training is in astrophysics not biology, the science does appears to be sound to me.
2. I do not believe for a second that NWBO would "sit" on the DMC's decision regardless of what it was. This news is obviously something that will materially impact the share price and to do so would not only expose them to shareholder lawsuits, but also expose them to possible criminal prosecution by the SEC. Ergo, we do not have the verdict yet because the DMC has not given it to NWBO yet.
3. The DMC is an utterly separate entity from NWBO. The DMC has no skin in a particular recommendation. Their chief concern is making sure that the results they analyze support their ultimate recommendation and to insure the integrity and safety of the trial. A miss-step there could expose them to substantial liability.
4. The primary endpoint was set very low for this trial. An improvement in PFS of roughly 1/3rd that seen in previous trials.
5. Now this one is anecdotal, but from personal experience. When I was doing my lab work in college and I came up with a statistical result that was far out of the bounds of what I expected, my first inclination was not "eureka!", it was "oh crap, what did I screw up?". A negative result was easy to verify. As was a result in line with expectation. The only result that made me burn the midnight oil and do the whole blasted thing over again was something unexpected. To me, the expected results here would be either ineffective, or a PFS improvement in the neighborhood of 6 additional months.
That is just my conclusion and why I am not worried about the delay. I'm just anxious to get the word on it.
