The U.S. Food and Drug Administration today approved Makena (hydroxyprogesterone caproate) injection to reduce the risk of preterm delivery before 37 weeks of pregnancy, in pregnant women with a history of at least one spontaneous preterm birth.

The drug is not intended for use in women with a multiple pregnancy, such as a twin pregnancy, or other risk factors for preterm birth.

The FDA approved Makena under the agency’s accelerated approval regulations that allow promising drugs to be approved based on a surrogate endpoint benefit (here, reducing the risk of delivery before 37 weeks of pregnancy) that is reasonably likely to predict a clinical benefit.

A health care provider would give Makena once a week by injection into the hip. Treatment should begin at 16 weeks and no later than 21 weeks of pregnancy.
