Improve Mfg. Deficiencies to Boost ANDA Approval: FDA

Share

An FDA analysis finds a first-cycle approval rate of 13% for modified release tablet ANDAs submitted between 2017 and 2019. “Deficiencies identified in multiple review disciplines are responsible for the low first-cycle approval rate,” a CDER chart says. “Most of the cited manufacturing process-related deficiencies are unit operations. Avoiding the most common manufacturing deficiencies can improve the quality of applications, which can improve the first-cycle approval rate.”

The chart shows that 1,285 manufacturing-related deficiencies were cited during the first review cycle, including 275 cited in the complete response letter. In the 87% of the 186 modified-release tablet ANDAs studied that were issued a complete response letter, 51% of the applications were cited with process inadequate recommendations and 33% of applications were cited with facility inadequate recommendations. Some 90.7% of the complete response applications were caused by multiple review disciplines being inadequate.
