    Investigator Brochure (IB)

    An Investigator's Brochure (IB) is the comprehensive document, updated at least annually, that summarizes all available clinical and non-clinical data on an investigational product, allowing investigators to assess the benefit-risk balance for trial participants.

    Per ICH E6(R3), the IB must be provided to every investigator before site activation and re-issued whenever new significant safety or efficacy information emerges. The IB drives the safety language in the ICF, the risk-mitigation strategies in the protocol, and the reference safety information used for SUSAR assessment.

    Maintaining an IB across multiple ongoing studies and expanding safety datasets is logistically intensive. AI-assisted IB authoring keeps non-clinical, clinical, and safety sections synchronized with the underlying source documents and flags downstream documents (protocols, ICFs, DSURs) that require updating after each IB revision.
