An Investigator's Brochure is a document that compiles clinical and nonclinical data on an investigational product, including formulation details, pharmacology, toxicology, pharmacokinetics, and prior human experience from completed and ongoing studies. It provides investigators, regulatory authorities, and ethics committees with the information needed to assess potential risks, follow dosing guidance, manage expected adverse reactions, and conduct the clinical trial safely.
In translation and localization, Investigator's Brochure content appears in clinical trial applications, ethics committee submissions, site initiation packages, and investigator-facing documents. Translators also work with toxicology findings, reference citations, dose units, and safety narratives and tables, and must keep terminology aligned with the protocol, informed consent form, and clinical study report.
A common mistake is translating “investigator” as “surveyor” or “researcher” instead of the accepted role title in local clinical trial regulations. Inconsistent rendering of toxicology terms or units such as mg/kg can also make nonclinical safety information unreliable, create confusion in serious risk assessment, and delay regulatory and ethics committee approval.
FDA, CE/MDR and NMPA reviewers assess the submitted wording itself. Regulatory bodies require traceable, accountable translation, and an inconsistent term can delay or fail a submission.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
