March-in Rights: A Lost Opportunity To Lower US Drug Prices 18/05/2017 by Steven Seidenberg for Intellectual Property Watch 17 Comments It appears not just unfair, but absurdly so. The US government paid for research that produced a patented drug, the patents were licensed exclusively to a Japanese firm, and that firm is now committing price discrimination against the US. Astellas Pharma is selling its anti-prostate cancer drug, Xtandi, for over $129,000 per year per patient in the United States – triple the price of the drug in Japan. Alas, this situation is not unusual. Many drugs that were financed by US taxpayers are sold in the US at exorbitant prices, but are much cheaper in other high-income industrialized nations. This differential price problem could be solved easily. However, the US government has consistently refused to exercise its march-in rights in order to lower drug prices.
