We could make faster progress against cancer by changing the way drugs are developed. In the current system, if
a promising compound can’t be patented, it is highly unlikely ever to
make it to market — no matter how well it performs in the laboratory. The development of new cancer drugs is crippled as a result.
The reason for this problem is that bringing a new drug to market is
extremely expensive. In 2001, the estimated cost was $802 million; today
it is approximately $1 billion. To ensure a healthy return on such
staggering investments, drug companies seek to formulate new drugs in a
way that guarantees watertight patents. In the meantime, cancer patients
miss out on treatments that may be highly effective and less expensive
to boot. In 2004, Johns Hopkins researchers discovered that an
off-the-shelf compound called 3-bromopyruvate could arrest the growth of
liver cancer in rats. The results were dramatic; moreover, the
investigators estimated that the cost to treat patients would be around
70 cents per day. Yet, three years later, no major drug company has
shown interest in developing this drug. The hormone melatonin, sold as
an inexpensive food supplement in the United States, has repeatedly been
shown to slow the growth of various cancers when used in conjunction
with conventional treatments. Early this year, another readily available
industrial chemical, dichloroacetate, was found by researchers at the
University of Alberta to shrink tumors
in laboratory animals by up to 75 percent. However ... dichloroacetate
is not patentable, and the lead researcher is concerned that it may be
difficult to find funding from private investors to test the chemical. Potential anticancer drugs should be judged on their scientific merit, not on their patentability.

To explore several cancer cures which have shown dramatic potential,
yet are not being studied for lack of funds due to inability to patent
the process, .
Why are these very promising treatments not being fast-tracked as the
expensive AIDS drugs were? For a top MD's revealing comments on this,. And for why the media won't feature these promising cancer treatments in headlines, .
