Phase 3

This study is about checking the safety of TAK-881 when used for a long time in people with Primary Immunodeficiency Diseases (PIDD). PIDD is when the body's defense system doesn't work well. TAK-881 is a special medicine called an immunoglobulin (IgG) given through a drip. People in the study will get TAK-881 at the same level they had in an earlier study called TAK-881-3001. Every 2, 3, or 4 weeks, they will visit the clinic for a check-up. The study lasts at least 6 months, but some might continue for 2 more years if needed, depending on their test results.

  • Participants must have finished the earlier study, TAK-881-3001.
  • Clinic visits are every 12 weeks, with a possibility of 2 years of treatment.
  • Some risks include the need for informed consent and possible health impacts if new conditions appear.
