CGMP Deviations at Hangzhou Yiqi Biotechnology

Share

An FDA review of records it requested from Hangzhou Yiqi Biotechnology Co., an active pharmaceutical ingredient manufacturer in Hangzhou, Zhejiang, China, found significant deviations from current good manufacturing practice (CGMP) regulations for active pharmaceutical ingredients (APIs). A just-released 4/15 Warning Letter says the specific deviations were:

  • failure to demonstrate that the firm’s manufacturing process can reproducibly manufacture an API meeting the predetermined quality attributes;
  • failure to validate and verify the suitability of analytical methods;
  • failure to design a documented, ongoing sterility testing program to monitor the stability characteristics of API and to use the results to confirm appropriate storage conditions and retest or expiry dates; and
  • failure to demonstrate that water used in the manufacture of APIs is suitable for its intended use.

FDA placed all of the company’s drugs and drug products offered for import into the U.S. on a 1/30 Import Alert. Hangzhou was told to correct the deviations promptly and to respond with a list of specific steps it has taken to address the deviations and prevent their recurrence, with a schedule for completing the corrections.
