Source excerpt · automated text-match check

Failure to establish an impurity profile for identified and unidentified impurities and failure to ensure all test procedures are scientifically sound and appropriate to ensure that your API conform to established standards of quality and purity.

Components & suppliers

Failed to test the identity of each batch of incoming production material and appropriately qualify suppliers to rely upon their Certificate of Analysis.

Findings extracted from the letter

Selected FDA passages, not the complete letter.

01
Failure to clean equipment and utensils to prevent contamination or carry-over of a material that would alter the quality of the intermediates and API beyond the official or other established specifications.
02
Failure to ensure that materials are handled and stored in a manner to prevent degradation, contamination, and cross-contamination.
03
Failure to establish an impurity profile for identified and unidentified impurities and failure to ensure all test procedures are scientifically sound and appropriate to ensure that your API conform to established standards of quality and purity.
04
You failed to conduct a comprehensive evaluation of your manufacturing processes to identify potential impurities. For example, you did not validate your method for testing for organic impurities in **(b)(4)** API, nor did you have a specification for these impurities. Chromatograms from your unvalidated method showed unknown, unintegrated impurities that were not quantified. As a result, these peaks were not fully considered when making your release decisions.
05
Failure to test the identity of each batch of incoming production material and appropriately qualify suppliers to rely upon their Certificate of Analysis.
06
You failed to conduct an identity test on each lot of raw material used in the manufacture of your API. You instead relied on the certificates of analysis (COAs) from your supplier without adequately qualifying them.
