CCDM Risk-Based Monitoring 2

Question 1

What does 'targeted source data verification' (targeted SDV) mean in a risk-based monitoring plan?

Accepted Answer

Selecting specific critical data fields or subject records for SDV based on risk assessment rather than checking all data

Answer

Targeted SDV focuses verification efforts on data fields defined as critical or high-risk (e.g., primary endpoints, eligibility criteria, serious adverse events) rather than performing 100% SDV across all data.

Question 2

According to ICH E6(R2), which entity is primarily responsible for implementing a quality management system for a clinical trial?

Accepted Answer

The sponsor

Answer

ICH E6(R2) Section 5.0 places the responsibility for implementing a quality management system — including risk identification and risk-based monitoring — squarely on the sponsor.

Question 3

In risk-based monitoring, what is the purpose of establishing a risk threshold for a KRI?

Accepted Answer

To define the point at which a KRI value triggers a predefined escalation or investigation action

Answer

Risk thresholds define actionable cut-points; when a KRI value crosses the threshold, it generates a signal that prompts investigation, contact with the site, or an unplanned visit.

Question 4

Which statistical technique is commonly used in centralized monitoring to identify sites that are statistical outliers compared to the overall study population?

Accepted Answer

Z-score and interquartile range (IQR) analysis

Answer

Z-scores and IQR-based outlier detection are standard centralized monitoring tools that flag sites where data distributions (e.g., adverse event rates, missing data rates) deviate significantly from the study-wide norm.

Question 5

What action should a clinical data manager take when a KRI exceeds its predefined threshold during centralized monitoring review?

Accepted Answer

Escalate findings per the monitoring plan, which may include contacting the site and documenting the signal

Answer

Exceeding a KRI threshold triggers the escalation process defined in the monitoring plan, which typically includes documenting the signal, contacting the site monitor or investigator, and determining whether additional oversight is needed.
