Some board members apparently were able to see a leaked version of the trial protocol. They have suggested that there was a prospective end point to the trial of November 2018.
Per LP at ASCO, a spring refresh was under way. I expect this process to take 1-3 months dependent on money (low) and staffing (low).
Overall, I agree with your assessment that the behavior of the company supports the contention that NWBO believes the treatment and "placebo" arms of the trial are similar.
Additionally, LP focuses on the fat tail. This concerns me. There is no dual arm endpoint, so what exactly are the statisticians and SAB looking for to trigger un-blinding? This would have been a good discussion for an investor update, the lack of management guidance is causing FUD.
I contend that the placebo arm likely did well years 1-2, but may be eventing years 3-4. I am basing this on open trial arm data and similar trial placebos arms. If for some reason the placebo arm out survives the treatment group, its still a muddy finish. It may be a good time for the company to try to improve its transparency and governance. I am starting to rant so I guess I'll stop.
