Adverse Event Management Flashcards

What is a Data Safety Monitoring Board (DSMB) and its primary function in clinical trials?

Answer: An independent committee that periodically reviews accumulating safety data to protect subject welfare and trial integrity

A DSMB (or IDMC) is an independent group of experts that reviews unblinded safety and efficacy data at interim timepoints to recommend trial continuation, modification, or termination.

When grading the severity of adverse events in oncology trials, which standard grading system is most commonly used?

Answer: NCI Common Terminology Criteria for Adverse Events (CTCAE)

The NCI CTCAE provides standardized terminology and severity grading (Grades 1-5) for adverse events in cancer clinical trials and is widely adopted across therapeutic areas.

What is the purpose of an annual Development Safety Update Report (DSUR)?

Answer: To provide a comprehensive annual review of the investigational product's safety profile and risk-benefit assessment

The DSUR (guided by ICH E2F) is submitted annually to regulatory authorities during clinical development to summarize worldwide safety experience and the current benefit-risk profile.

If a subject experiences an SAE after the last dose of investigational product, during the follow-up period specified in the protocol, the investigator should:

Answer: Report the SAE to the sponsor per protocol-specified timelines since it occurred during the defined follow-up window

SAEs occurring during the protocol-defined follow-up period must be reported regardless of causality; the protocol defines how long post-treatment events must be captured.

The MedDRA coding system is used in clinical trials to:

Answer: Standardize medical terminology for adverse event classification and regulatory reporting

MedDRA (Medical Dictionary for Regulatory Activities) is the internationally recognized medical terminology system used to classify adverse events and medical conditions in regulatory submissions.

Unblinding of treatment assignment in a blinded trial for safety reporting purposes should:

Answer: Follow a pre-defined emergency unblinding procedure that minimizes unnecessary unblinding while protecting subject safety

Trials should have documented emergency unblinding procedures that allow rapid access to treatment code when medically necessary, while limiting unnecessary unblinding to preserve trial integrity.
