Which statement best describes the tone of the Investigator's Brochure?

• A. It should be concise, objective, and non-promotional
• B. It should be promotional and advocacy-oriented
• C. It should be primarily a patient's education document
• D. It should emphasize market advantage

Answer: (A)

The tone of the Investigator's Brochure should be concise, objective, and non-promotional because the IB is a scientific reference for investigators to understand the investigational product's safety, pharmacology, and the plan for the trial. An objective, neutral presentation ensures data are interpreted correctly, supports regulatory review, and helps protect participants by clearly conveying risks and uncertainties without hype. Promotional language could bias investigators or mislead about benefits and risks. It’s not intended as patient education—that role belongs to patient-facing documents—and it should not emphasize market advantage, which would undermine the scientific and regulatory purpose of the document.
