An Extension Study of TAK-664 for Japanese People With Primary Immunodeficiency Disease
About the study
This study is an extension study for participants with primary immunodeficiency disorders who were previously treated with IGSC, 20% in the TAK-664-3001 study.

The main aim of this study is to check for side effects from long-term treatment with IGSC, 20% . This medicine is not yet licensed in Japan, so participants will be treated with IGSC, 20% until it becomes commercially available.
