Which document records that the investigator is informed in a timely manner of relevant information as it becomes available?

• A. Master Randomization List
• B. Any Revision to Trial Documents
• C. Dated, Documented Approval/Favorable Opinion of IRB/IEC of Trial Related Documents
• D. Investigator's Brochure Updates

Answer: (D)

The key idea is how investigators stay informed about new information that could affect safety or trial conduct. The Investigator’s Brochure is the central document that describes the investigational product to the sites. When new, relevant information becomes available—such as safety findings, updated dosing guidance, or new risks—the sponsor must promptly issue updates to this brochure. These IB updates serve as the official record that investigators have received and reviewed the latest information, ensuring they can adjust their practices and consent processes accordingly. Other items don’t fulfill this role as directly. A master randomization list concerns allocation and isn’t about communicating new safety or product information. Revisions to trial documents happen, but they don’t by themselves represent the mechanism for informing investigators of new information. IRB/IEC approvals relate to ethics oversight of documents, not the ongoing dissemination of safety information to investigators. The Investigator’s Brochure Updates are specifically the mechanism that records and delivers new information to investigators in a timely manner.
