DCA which has been found to reduce the size of cancerous tumors. Dr. Dario Alterieri from the University of Massachusetts agreed that the drug should be tested for its side effects and safety issues. However, there is no patent on this drug.
Since there is no patent on DCA and no pharmaceutical company owns this drug, CTV reported that drug companies will not want to bring this drug out on the market or conduct studies on this drug due to the fact that they can't make a profit off a drug that can be inexpensively produced.
CTV News also mentioned that it costs nearly $100 million dollars for testing to become completed on a new drug, so it looks like everything comes down to a matter of money. Of course, there is another case like Dr. Burzinski's which is the only case I know of where a doctor received five court acquittals with a "Not Guilty Verdict" in Houston, Texas for coming out with his treatment for Cancer that has been hidden from us all since 1977.
