On February 3, 2011, the Food and Drug Administration approved the drug Makena (hydroxyprogesterone caproate) for the reduction of the risk of certain preterm births in women who have had at least one prior preterm birth. KV Pharmaceuticals, the drug’s owner, received considerable assistance from the federal government in connection with the development of Makena by relying on research funded by the National Institutes of Health to demonstrate the drug’s effectiveness. It also obtained seven years of exclusivity under the Orphan Drug Act, obtained approval under FDA’s accelerated approval program, and received expedited review.
