Endpoints

Primary endpoints

  • {"endpoint_text":"- The primary endpoint, IL-1 β concentration in the blood within 24±6 hrs after symptom onset, will be analyzed in the full analysis set, which comes as close as possible to the IIT principle. A mixed linear regression model is calculated with the IL-1 β value (at 24±6hrs & 3 d) as the dependent variable, the randomized group, the IL-1 β value at baseline & the time point, the interaction of time + group, as independent variables and the patient as a random effect.","definition_or_measurement_approach":"IL-1β concentration in blood measured within 24±6 hours after symptom onset; analysis in the full analysis set using a mixed linear regression model with IL-1β (at 24±6 hrs & 3 days) as the dependent variable, randomized group, baseline IL-1β and time point as independent variables, interaction of time and group, and patient as a random effect."}

Secondary endpoints

  • {"endpoint_text":"- All secondary endpoints are analyzed descriptively, and differences between the two study arms are explored according to their level of measurement.","definition_or_measurement_approach":"Secondary endpoints will be analyzed descriptively; differences between study arms explored according to measurement level (no further per-endpoint definitions provided in the available JSON)."}
