Upon completion of a study, the investigator should do which of the following?

Investigators must formally close out a trial with the IRB/IEC.

ICH E6(R2) 4.13.2:“Upon completion of the trial, the investigator/institution should provide the IRB/IEC with a summary of the trial’s outcome.”

21 CFR 312.66:Reinforces investigator’s duty to keep IRB informed throughout study lifecycle.

This applies regardless of whether outcomes were positive, negative, or inconclusive. IRBs are not concerned with sponsor payments (B) or publications (D).

Thus, the correct answer isA (Provide final report to IRB/IEC).
