Investigational Product Exposure Section

ICH E3 includes extent of exposure within safety evaluation so reviewers can understand dose, duration, treatment exposure, and related context for interpreting safety findings. Do not confuse exposure with investigational-product accountability, which tracks receipt, storage, dispensing, return, and reconciliation rather than the participant-level amount/duration of treatment received.

Quick answer

An Investigational Product Exposure section summarizes how much study treatment participants actually received so safety findings can be interpreted against dose and duration.
