Mixed Views on FDA Mifeprex Monitoring
A Government Accountability Office (GAO) review says that stakeholder organizations have mixed views about FDA monitoring of Mifeprex since its 2000 approval with an indication for the medical termination of early pregnancy. Members of Congress asked GAO to review FDA’s 2016 relabeling of Mifeprex with a revised indication and the agency’s subsequent monitoring of the drug and its safety.
FDA followed its standard review process when it approved the application and revised labeling reflecting certain changes to the indication and dosing regimen, GAO found. The report outlines a variety of monitoring activities the agency has used and says the monitoring has not identified significant concerns with Mifeprex safety and use.
GAO found that the views of stakeholder organizations were mixed about FDA Mifeprex monitoring, It says that positive comments included that the agency has a comprehensive monitoring program and a robust adverse event reporting system. Criticisms included that adverse events may be under-reported and that FDA may only be aware of a fraction of them.
On the drug’s safety, the report says, positive comments included that the mortality rate associated with Mifeprex is extremely low. Safety concerns included that the revised labeling no longer requires patients to have a second visit with a healthcare provider and that certain safety issues may be exacerbated by the increased gestational age limit approved by FDA.
