Extending cancer patients' lives more profitable than preventing disease, says N.Y. Times scribe

Answer: It's not profitable enough.
According to The New York Times, "economic incentives encourage researchers to focus on treatment rather than prevention."
A recent piece written by Austin Frakt and distributed in an online Times' newsletter, "The Upshot," charges that the sitution stems from the "way the patent system interacts with the Food and Drug Administration's drug approval process" — an interaction that "skews what kinds of cancer clinical trials are run."
Those findings are based on the work of Heidi Williams, a MIT economics prof and MacArthur "genius" grant winner, and two other experts.
After patenting a drug, pharmaceutical companies "race the clock to show that their product is safe and effective" — so they can obtain FDA approval, Frakt notes. "The more quickly they can complete those studies, the longer they have until the patent runs out, which is the period of time during which profit margins are highest."
Drug companies have found developing meds "to treat late-stage disease is usually much faster than developing drugs to treat early-stage disease or prevention, because late-stage disease is aggressive and progresses rapidly."
That, in turn, "allows companies to see results in clinical trials more quickly, even if those results are only small improvements in survival."
Between 1973 and 2011, Frakt writes, "there were over 17,000 trials of patients with the lowest chance of survival…but only 500 for cancer prevention, which confer the longest survival gains."
Williams' study estimated that current incentives "led to 890,000 lost life-years among American patients found to have cancer" in one year alone.
The best way to address the problem, Frakt suggests, is to have the FDA more routinely give approvals based on "indications of improved health that can be measured more quickly than survival — so-called surrogate endpoints."
Another remedy might be to extend the period of a drug's market exclusivity to compensate for what's called the "commercialization lag."
