The job

Integrate current nonclinical and clinical knowledge relevant to investigators and safe study conduct.

Writer's control points

• Compare the prior and current evidence base.
• Maintain product and formulation identity.
• Integrate rather than list study findings.
• Make risks, uncertainties, and safety guidance visible.
• Record why sections changed or remained stable.

An IB is a living synthesis. Reuse requires change control and source traceability, not annual copying.
