Which item defines the safety endpoints to be monitored and how they are measured?

• A. The type of safety endpoints to be monitored
• B. Specification of safety parameters
• C. The trial's randomization scheme
• D. The marketing authorization status

Answer: (B)

The key idea is clearly defining what will be monitored for safety and exactly how those safety measurements will be taken. The specification of safety parameters lays out both the endpoints and the methods, including what will be measured (for example, adverse events, laboratory abnormalities, vital signs), how each parameter is defined and graded, the units and thresholds used, the timing and frequency of measurements, and the data sources and assessment methods. This level of detail ensures consistent data collection across sites and investigators, enabling reliable safety assessment and timely signal detection.

The other aspects described are not about defining the actual safety endpoints or the measurement methods. The type of safety endpoints to be monitored is broader and less precise without the measurement details. The trial’s randomization scheme and the marketing authorization status do not specify how safety is measured or monitored.
