Which document covers the decoding procedures for blinded trials?

• A. Shipping Records for Investigational Products and Trial-Related Materials
• B. Certificates of Analysis of Investigational Products Shipped
• C. Decoding Procedures for Blinded Trials
• D. Any Revision to Trial Documents

Answer: (C)

In blinded trials, there must be a defined process for when and how the treatment assignments can be revealed, who is allowed to reveal them, and how that information is recorded and protected. The document that lays out these exact steps—who may break the code, under what circumstances (such as medical emergencies), the method used to decode, and how unblinding is documented and safeguarded—is the decoding procedures for blinded trials. This dedicated document provides the authoritative guidance to preserve blinding where possible while ensuring patient safety and data integrity. Shipping records and certificates of analysis relate to the physical handling and quality of investigational products, not to how or when to decode blinded assignments. Revisions to trial documents cover changes to documents in general, not the specific rules for decoding.
