Not really, since I have believed that the Phase 3 trial should be a success since I first heard of NWBO and started investing more than half-a-decade ago and a long longer than say 2020.
The problem is that one can mismanage even the best science into failure and the trial is pretty ramshackle (it did not start as a Phase 3 trial for example and has been changed significantly over time including being effectively paused at one point and having patients added).
Despite the problems with the trial and the company that controls the commercialization of the science, the basic science is good and I think it should overcome those issues and allow the trial to be a success.
The problem with life is that what should be is not the same as what will be and that is the billion dollar question here.
