This novel approach to chemotherapy involves coating the drug in siRNA which first destroys the cancer's resistance to that drug. It could be customized depending on the particular mutations present in the tumor. No doubt, each variation would require a separate FDA approval, so it's economically impossible in the US. Please tell your oncologist friends in other countries so we can actually give this technology a run for the money.
Nevertheless, it looks like an unwinnable game of whack-a-mole, attempting to counter each successive mutation as it occurs. Merely monitoring the patient for such mutations would be financially onerous if not intractable, so to be sure, this is merely a stalling tactic which might allow some patients to survive until they figure out a more direct approach, such as 3-bromopyruvate. But what a difference a few years could make.
