Details
Review of the non-viable particle count (NVPC) continuous monitoring from the ***, which is used to transport *** vials from the filling line to the *** show frequent communication errors. These occur when the unit fails to have an adequate WFI signal or power to the NVPC is lost, leaving gaps in the ability to report NVPC data. These communication errors were first documented in a maintenance notification, July 23, 2020, but no effective actions have been taken to ensure NVPC data is available continuously during batch production activities. For example, during line set-up, filling, and *** loading:
(1) For batch *** batch *** on January 19-20, 2024, there were 49 communication errors totaling 1 hours and 30 minutes of time. This included communication errors from *** on January 19, 2024, when *** vials were being loaded into the ***.
(2) For batch *** batch *** on April 7-8, 2024, there were 45 communication errors totaling 2 hours and 3 minutes of time. One communication errors lasted 41 minutes and 46 seconds.
(3) For batch *** batch *** on April 1-2, 2024, there were 54 communication errors totaling 58 minutes of time.
The procedure 0317-SOP-MFG-00037 requires a breakdown notification if the errors continue during the batch, but provides no specific instructions describing the threshold that would require a notification. No breakdown notification was generated for batches ***.
Additionally, the alarms are not being acknowledged in a timely manner with comments entered to describe the activity occurring. For example, during batch *** communication errors on April 2, 2024 at *** (8 minutes 43 seconds duration), *** (8 minute 56 seconds duration), and *** (8 minute 42 seconds duration) were not acknowledged in the system until *** on April 2, 2024. The comment was written as “NA” and did not assess the impact of the loss of NVPC data prior to loading *** vials into the ***.
