FDA Panel Shoots Down Makena’s Continued Availability
FDA’s Obstetrics Reproductive and Urologic Drugs Advisory Committee10/19 voted 14 to 1 to recommend the market withdrawal of Covis’ Makena (hydroxyprogesterone caproate injection, 250 mg/mL, once weekly) because data show the accelerated-approval drug is not effective. It was approved in 2011 for reducing the risk of pre-term birth in women with a singleton pregnancy.
During the panel meeting, FDA reiterated its position expressed in a briefing document released in advance of the hearing that argued strongly that the drug is not effective and has known risks. FDA said Makena has not been shown to improve neonatal outcomes from premature birth, and that its confirmatory trial “failed to show that Makena has any benefit to newborns. Data from this trial, taken together with other evidence, also fail to show that Makena reduces the risk of recurrent preterm birth,” it said in arguing that the drug should be withdrawn from the market.
Covis argued to keep the drug on the market while it conducted a prospective, randomized, double-blind, placebo-controlled trial, but FDA said this would take at least 10 years to conduct. The agency said such a trial is not feasible while Makena is still on the market, and patients are “less likely to enroll in trial for a drug approved to treat a serious condition and risk receiving a placebo when they can simply receive the drug by not enrolling in such a trial.”
