The Ultimate Method for Performing Pharmaceutical Investigations

The Ultimate Method for Performing Pharmaceutical Investigations

I spent 14 years as an FDA Investigator and issued more Form FDA-483s than I care to count. For the 13 years afterwards, including work supporting a consent-decree remediation and return to compliance, I built and ran the investigation systems companies use to keep that from happening to them.

This is that system, in full, for the first time in one document.

Most investigation training teaches you to fill out a form. This teaches you how an FDA Investigator actually reads your file, what makes a root cause defensible versus wishful, and why the investigations that survive an inspection are consistently the same ones that cost less to run.

What's inside (60 pages):

• The complete 14-step investigation method, from event detection through management review, covering fact establishment, interviews, root cause analysis, extent of condition, product disposition, regulatory reportability, and CAPA effectiveness
• A dedicated section on out-of-specification investigations: Phase I and Phase II, the prohibition on testing into compliance, and what FDA actually allows with outlier testing (this alone prevents a common, serious citation)
• Where investigations break down: the human error trap, the supervisor-only interview, premature closure, and the specific CAPA mistakes that turn a deviation into a Warning Letter
• Four full case studies walked through the entire method, not root-cause anecdotes
• Regulatory scope guidance across finished pharmaceuticals, API, biologics, sterile products, devices (including the QMSR), and combination products
• 11 ready-to-use worksheets: problem statement, investigation plan, event timeline, evidence log, interview record, hypothesis verification, extent of condition matrix, product impact assessment, regulatory reportability checklist, CAPA effectiveness plan, and closure summary
• A full regulatory reference list with linked citations

Built for quality, regulatory, and manufacturing professionals who are tired of guessing what "thorough" means until an Investigator tells them it wasn't.
