Warning Letter: Failure to control spreadsheets, data integrity (ucm538068)

Tags:

Ofni Systems
For multiple sterile drug product lots, your original data showed failing results, but data you reported showed passing results. This discrepancy was not adequately explained.
You stored original data in an “unofficial” and uncontrolled electronic spreadsheet on a shared computer network drive. Your analyst stated that original data was first recorded in this “unofficial” spreadsheet and transcribed later to an “official” form. This spreadsheet showed failing results above the limits you established in your procedure, PCH 035 Visible Particle Determination in use prior to September 1, 2014.
