During a March 2024 inspection of a finished drug company in China, FDA investigators Brandy N. Lepage and Karen A. Briggs encountered company management that limited access to manufacturing areas, disallowed photography, and supplied fewer documents than requested, many of them heavily redacted.
The Redica Systems model identified 19 major deficiencies and two minor ones across four quality systems from a five-item, four-page 483.
While this analysis of the 483 paints a picture of a company with major issues across four quality systems, viewed in isolation, it would not seem to solidly predict a warning letter, especially since no critical deficiencies were identified.
However, as shown by the additional detail in the warning letter, the 483 does not tell the entire story of the inspection, a valuable lesson for those who analyze inspection documents.
