An anonymous reader shares an article: There are 7,000 rare diseases affecting 25 million to 30 million Americans. The average drug approved under the Orphan Drug Act of 1983 (ODA), which governs rare disease approval, costs $118,820 per year. Assuming a similar cost, if a single drug were approved under the ODA for 10% of rare diseases, the total would exceed $350 billion annually -- more than 10 percent of the total amount that America spends on health care and much more than the health care costs attributable to either diabetes or Alzheimer's disease and other forms of dementia. If this seems far-fetched, consider the two drugs for treating Duchenne muscular dystrophy that the FDA approved in the last six months: eteplirsen, which is sold by Sarepta Therapeutics and costs $300,000 annually per patient, and deflazacort, which is sold by Marathon Pharmaceuticals and costs $89,000 annually per patient. However, approval of such costly drugs exposes an uncomfortable truth: scientific discovery has outpaced health care economics. [...] In the United Kingdom, the National Institute for Health and Care Excellence (NICE) determines the cost effectiveness, or value, of newly approved drugs based on their impact on quality-adjusted life years. These determinations inform the National Health System's (NHS) treatment-coverage decisions. In contrast, the FDA is prohibited from considering cost or value in its decision making, and there is no U.S. governmental equivalent of NICE.
