Who should be informed of storage determinations?

• A. All involved parties
• B. Sponsor only
• C. Regulators only
• D. Trial participants only

Answer: (A)

Storage determinations set how materials and samples must be stored, for how long, and under what conditions. This information affects anyone who handles, monitors, or relies on those materials—site investigators and staff, the sponsor, and often regulatory bodies. When storage conditions or durations change, all those involved need to know to ensure proper handling, maintain data integrity, and protect participant safety. Because of these broad responsibilities, informing all involved parties is the correct approach.
