The decision follows repeated efforts by Swiss drugmaker Covis Pharma to keep Makena on the U.S. market while it conducted additional studies. The medication was the only drug approved in the U.S. to help reduce the risk of early births in women with a history of preterm deliveries.
In recent months, Covis finally bowed to FDA pressure, proposing a “winding down” period of several months so that women taking the drug could complete their treatment.
The FDA rejected that and said Thursday that the action against Makena and several generic versions should take effect immediately.
“Makena and its generics are no longer approved and cannot lawfully be distributed in interstate commerce,” the agency said in a statement.
The injectable drug is a synthetic version of the hormone progesterone, which helps the uterus sustain pregnancy. It can cause side effects, including blood clots, depression and allergic reactions. Given those risks, FDA staffers previously concluded there was no upside to keeping the drug available, given its lack of confirmed benefit.
The final decision by FDA Commissioner Robert Califf and the agency’s chief scientist marks the first time the agency formally forced the removal of a drug that it initially approved based on promising early data. In all prior cases, drugmakers voluntarily pulled medications after the FDA made clear it intended to order removal.
The FDA expedited Makena’s approval in 2011 based on a small study suggesting it reduced rates of premature birth in women who had previously had trouble bringing a pregnancy to term. But results from a 1,700-participant study completed in late 2018 showed the drug neither reduced premature births — as originally thought — nor resulted in healthier outcomes for babies.
