Premature Termination or Suspension Section

A Premature Termination or Suspension section covers the unplanned early-stop pathway: immediate participant considerations, notification, documentation, follow-up, and responsibility allocation. It is distinct from routine planned study closeout.

Quick answer

A Premature Termination or Suspension section explains who acts, who is notified, how reasons are documented, and how participants and records are protected if the trial stops early or is suspended.

Key details

Core IssueICH E6(R3) sets responsibilities for prompt communication, participant protection, documentation of reasons, and appropriate notifications when a trial or site is prematurely terminated or suspended.

Important caveats

Scope Boundary

Keep this separate from Study Closeout, which covers planned end-of-study activities. Exact notification recipients and timelines depend on who initiates the stop and applicable requirements.

State decision authority, immediate participant-safety and treatment-continuity steps, investigator/sponsor/regulator/ethics notifications as applicable, documentation of reasons, record handling, and required follow-up.

Purpose
