API Deviations Found in Teva Hangzhou Plant
A 9/26-9/29 FDA inspection at Teva Pharmaceutical and Chemical (Hangzhou), Zhejiang, China, found significant deviations from current good manufacturing practice for active pharmaceutical ingredients, according to a 4/5 Warning Letter. Specific deviations cited in the letter include:
- failing to establish written procedures to monitor the progress and control the performance of processing steps that may cause variability in API quality characteristics; and
- failing to establish a sampling plan based on scientifically sound sampling practices.
The company’s responses to the findings were inadequate, FDA says. Teva was told to respond with a list of specific actions taken since the inspection to correct the deviations and prevent their recurrence, with a timetable for completion.
