While it would be great to learn that the King, or any other major newsmaker, was getting DCVax-L for what would be considered an off label use, it's not nearly as important as the UK regulators saying we have an approval.
In the past celebrities often haven't seemed to have gotten the best treatments, at least not when it comes to taking experimental products. If they do, it's generally not until the SOC treatment is clearly seen to be failing. No doubt they get some of the finest physicians, but not necessarily the ones doing a great deal of experimental work. I doubt if the treatment protocols for most celebrity treatment is ever made public, whether successful, or not.
