What is the purpose of providing relevant and current scientific information about the investigational product to the investigator?

• A. To support the sponsor's marketing strategy
• B. To enable the investigator to assess risks and scientific rationale
• C. To guarantee immediate trial approval
• D. To document the investigator's payment terms

Answer: (B)

The main idea is that investigators must have up-to-date, scientifically solid information about the investigational product so they can judge whether the risks are acceptable given the potential benefits and understand the scientific rationale for the study. This information, typically provided in the Investigator’s Brochure, covers what is known about the product’s pharmacology, toxicology, prior clinical data, and the rationale behind study design, including dose selection and endpoints. With this context, the investigator can meaningfully assess risk–benefit, determine appropriate inclusion criteria and monitoring plans, and communicate accurate information to participants as part of informed consent. This requirement supports safe and ethical conduct of the trial and ongoing safety oversight, rather than marketing aims, guaranteed approval, or payment terms.
