Study Endpoints

Primary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs and Non-serious TEAEs
From the first dose of the study drug in the current extension study TAK-664-3002, up to 3 years post-dose

TEAEs were defined as adverse events (AEs) with onset after date-time of first dose of study drug (intravenous immunoglobulin \[IGIV\] or IGSC), or medical conditions present prior to the start of study drug (IGIV or IGSC) but increased in severity or relationship after date-time of first dose of study drug (IGIV or IGSC). A serious TEAE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important.

Number of Participants With Drug-related and Non-related TEAEs
From the first dose of the study drug in the current extension study TAK-664-3002, up to 3 years post-dose

TEAEs were defined as adverse events (AEs) with onset after date-time of first dose of study drug (intravenous immunoglobulin \[IGIV\] or IGSC), or medical conditions present prior to the start of study drug (IGIV or IGSC) but increased in severity or relationship after date-time of first dose of study drug (IGIV or IGSC). Any TEAE that was recorded by the investigator as "probably related" or "possibly related" to study drug was considered as study drug related AE, and any AE recorded as "unlikely related" or "not related" was considered as unrelated AE.

Number of Participants With Severe, Local and Systemic TEAEs
From the first dose of the study drug in the current extension study TAK-664-3002, up to 3 years post-dose

A severe TEAE was an AE that caused considerable interference with the participant's usual activities. Local TEAEs were defined as AEs that were included in the MedDRA Higher Level Group Term "administration site reactions" or contained the phrase "injection site" or "infusion site". Systemic TEAEs were defined as AEs that were not included in the Medical Dictionary for Regulatory Activities (MedDRA) Higher Level Group Term "administration site reactions" and did not contain the phrase "injection site" or "infusion site".

Number of Participants With TEAEs Leading to Premature Discontinuation From Study and Infusion-associated TEAEs
From the first dose of the study drug in the current extension study TAK-664-3002, up to 3 years post-dose

Infusion associated TEAEs were defined as any TEAE that began during study drug infusion or within 72 hours of completion of study drug infusion. TEAEs leading to premature discontinuation from study and infusion-associated TEAEs were reported.
