Q: If Notes to File can be regulatory red flags, should we quit using them?
A: No, and here's why...
Regulatory inspections are often conducted long after the conclusion of the study. When an FDA investigator asks you a question about an anomaly five years after it’s happened, will anyone recall the circumstances well enough to satisfy the regulator’s concerns? You’ll be doing yourself a huge favor if you write NTFs that answer the questions regulators might one day be asking you.
