I am often asked by industry colleagues that if I had to pick just one “favorite” federal regulation what would it be?  The answer is easily 21 CFR 812.100, as this regulation embodies 95% of the investigational site non-compliances  I observe as I conduct clinical investigator audits. Let me elaborate.

21 CFR 812.100 falls under Subpart E- Responsibilities of Investigators of the IDE Regulations.  This regulation succinctly details investigator responsibilities in just two sentences.
