OIG: FDA takes too long to review generic drugs

Pharma Compliance Alert, June 18, 2008

The FDA exceeded the mandated review period for almost half of the Abbreviated New Drug Applications (ANDA) submitted for generic drugs in 2006, according to an OIG report.
 
Federal law requires the FDA to approve or disapprove original ANDA within 180 days of submission. The OIG examined 989 original ANDAs under review during 2006. OIG also surveyed FDA’s Office of Generic Drugs (OGD) division reviewers assigned to a sample of 105 ANDAs with review times greater than 180 days in at least one OGD division. Three OGD divisions review all ANDAs: Chemistry, Bioequivalence, and Labeling.
 
The OIG found:
  • FDA disapproved 96% of original ANDAs under review in 2006 because they did not meet FDA review standards
  • Almost half of Chemistry review times exceeded 180 days.
  • Many review times in other OGD divisions exceeded 180 days
  • In a sample of ANDA reviews exceeding 180 days, most reviews did not begin before the 180-day periods expired
  • FDA prioritization practices affect ANDA review times
 
The OIG recommended the FDA:
  • Identify common ANDA deficiencies
  • Offer more guidance to the industry to decrease the percentage of disapproved original ANDAs
  • Increase the percentage of original ANDAs reviewed by all divisions within 180 days
  • Implement new prioritization practices
