In the Effects in Humans: Introduction, which topics may be included when available?

• A. Pharmacokinetics, Bioavailability, Population subgroups, Interactions, and Other PK data
• B. Safety data only
• C. Manufacturing details
• D. Labeling copy

Answer: (A)

In this part of the Investigator’s Brochure, the focus is on what has been learned about the drug’s behavior in humans. When available, the Introduction to Effects in Humans may include topics that describe human pharmacology, such as pharmacokinetics, bioavailability, how these data might differ in population subgroups, and any drug–drug interactions, along with other PK data. This content helps readers understand how the drug acts in people, beyond safety observations. Safety data, manufacturing details, and labeling text are covered in other sections, so they aren’t the focus here.
