What is the Investigational Product (IP) responsible for at the site level?

• A. Storage, handling, accountability, labeling, dispensing, and return/disposal.
• B. Only storage.
• C. Only labeling.
• D. Only disposal.

Answer: (A)

The site-level management of the Investigational Product includes every step that keeps the product safe, traceable, and compliant: proper storage under the required conditions, correct handling to maintain quality, maintaining accurate accountability and inventory, clear labeling for correct identification and instructions, dispensing to the right participant per the protocol, and handling return or disposal of unused product. All these elements work together to protect subject safety and trial integrity, so describing the IP responsibilities at the site as covering storage, handling, accountability, labeling, dispensing, and return/disposal is the most complete and accurate representation. Focusing on just one aspect, like storage or labeling alone, would miss the other essential components involved in proper IP management.
