FDA has released the form FDA-483 issued following a 3/4-3/11/2025 inspection at the Fujifilm Diosynth Biotechnologies Texas drug manufacturing facility in College Station, TX. The eight inspection observations were:

  • failure to adequately control the multi-product manufacturing areas to prevent potential cross-contamination;
  • the quality control laboratory controls used for in-process, release, and stability testing of a redacted intermediate do not include appropriate testing procedures that assure conformance to appropriate standards of quality and purity;
  • failure to follow a specific stability testing program;
  • the cleaning and sanitization program is deficient in preventing potential contamination in the controlled drug substance manufacturing areas.
  • environmental monitoring of classified processing areas in the redacted facility for the redacted intermediate manufacturing is deficient;
  • failure to exercise appropriate controls for the electronic data acquisition systems used for redacted intermediate manufacturing;
  • SOPs or work instructions are not followed or are inadequate; and
  • the intermediate hold times defined in the redacted intermediate batch records are inconsistent with the hold times defined in a redacted document.
