Population (analysis set)

Description

Intent-to-treat (ITT) population

The ITT population will include all randomized participants. The ITT participants will be analyzed according to randomized treatment, irrespective of the actual treatment received. All efficacy analyses will be performed using the ITT population.

Modified intent-to-treat (mITT) population

The mITT population will include all randomized participants. The ITT participants will be analyzed according to randomized treatment and who have been given at least one dose of treatment. The mITT population will be used for supportive analyses of the efficacy measurements.

Per protocol (PP) population

The PP population will include all participants in the ITT population with no major protocol deviations that may significantly impact data integrity or patient safety. The PP population will be used for supportive analyses of the efficacy measurements.

Safety population (SP)

The SP will include all randomized participants who have been given at least one dose of treatment (IVIG or placebo). The SP will be analyzed according to the actual treatment received. This set will be used for the safety analyses.
