The most likely scenario is that CHM agreed with MHRA in Nov that DCVax was precluded from approval.
That would have triggered an appeal process (which they (NWBO) were entitled to) that could take up to 6 months.
April 28 would be about 6 months. We'll see if I am right in the next week to 6 weeks.
The trial failed and then there was crossover, changed endpoint and then very questionable external controls used.
If what I say is accurate, no regulatory body would ever accept another application from NWBO for ANYTHING - after all this nonsense, game playing and attempts to do and end run around the regulators.
JMHO, good luck to all.
