Check a supplied Investigator's Brochure for declared human pharmacokinetics/product-metabolism and related effects-in-humans content, then compare its version/date with a supplied DSUR citation register. Use this skill when a clinical pharmacologist and medical or regulatory reviewer need a source-located IB PK-section completeness and version reconciliation. Example: "Please a clinical pharmacologist and medical or regulatory reviewer need a source-located IB PK-section completeness and version reconciliation." Do not use it to approve medical content, decide live-study conduct, recommend a dose, or determine a filing obligation.
