FDA Should Address Approval Rate Factors: GAO
The Government Accountability Office (GAO) says FDA should take additional steps to address factors that may affect approval rates of generic drugs in the first review cycle. A GAO report says that 12% of the 2,030 generic drug applications reviewed by FDA from FY 2015 through FY 2017 were approved in the first cycle. For applications not approved in the first cycle, it says, the application must undergo one or more subsequent review cycles to obtain approval, delaying the generic drug’s arrival to market.
GAO says it identified several factors that may have contributed to whether a generic drug was approved during the first review cycle, such as certain types of complex drugs that were less likely to receive approval in the first review cycle. The report says FDA has taken steps to increase the rate of generic drug approvals in the first cycle, such as increasing communication with applicants and introducing templates for reviewers to improve the consistency and clarity of their comments.
GAO recommended that FDA (1) take additional steps to address inconsistency in its written comments to generic drug application sponsors; and (2) assess the extent to which the timing of branded drug companies’ drug labeling changes affects the approval of generic drugs and take steps, as appropriate, to limit the effect. FDA concurred with the recommendations.
