Just because someone says publicly that DCVax-L doesn't work doesn't necessarily mean that is what they believe privately. People say things for financial reasons. Not pointing fingers, just an observation. :)
I can not speak for iclight, but I have never asserted DCVax-L does not work. I think it does work, but not as magically effective across the board as most here do.
I do believe the P3 trial failed, but that is not the same. Even if DCVax-L was working sufficiently well in the trial, psPD + x-over could destroy the results.
And this second paragraph is IMO, not an asserted fact.
