Aargh - another mystery!

Granny - Sydney Morning Herald- had lunch with a very high profile melanoma victim (stage four) Quote; "Working with the Sydney Melanoma Institute he is one of only twenty people worldwide trialing an immunotherapy treatment that combines a new drug with the better known Keytruda. His tumors are shrinking and he is pain free" for the rest see the end of the article.
Now, please explain, what is the new drug and why not name it???? What else could it be but ours, why is there no publicity?
Given that the take over is all but conceded, why not spread the (possible) news??
