Rick discussed genistein in 2012 and it was discussed again in 2015. See:
Six month follow up on Nilotinib trial.
Curcumin falls into the same category. It too is a tyrosine kinase inhibitor.
As I see the situation, it's not a case of nilotinib or nothing; it's not a case of doing nothing, while waiting years for the trials to complete; and it's not a case of paying the high price of nilotinib or having nothing.
