Share

An FDA 9/23-9/27/2024 inspection at the Yangzhou Sion Commodity Co. drug manufacturing facility in Yangzhou, Jiangsu, China, found significant violations of current good manufacturing practice (CGMP) regulations for finished drugs. A 3/12 Warning Letter says the specific violations were:

  • failure to test samples of each component for identity and conformity with all appropriate written specifications for purity, strength, and quality, and failure to validate and establish the reliability of a component supplier’s test analyses at appropriate intervals;
  • failure of the quality control unit to exercise its responsibility to ensure that manufactured drug products comply with CGMP and meet established specifications for identity, strength, quality, and purity; and
  • failure to ensure that laboratory records included complete data derived from all tests necessary to ensure compliance with established specifications and standards.

The letter acknowledges that the company is using a consultant to perform data integrity training. It strongly recommends that it also retain a consultant to audit its operation and assist in data integrity remediation to meet FDA requirements.

FDA placed the firm’s products on a 1/31 Import Alert. Yangzhou was told to correct violations promptly and to respond with a list of specific actions it has taken to address the violations and prevent their recurrence, with a schedule for completing the corrections.
