Brief Summary
The main aim of the study is to check side effect from the study treatment with TAK-771 in long term. Participants can have taken part in the previous study TAK-771-3004 (NCT05150340). For those who can take part, the participants will receive injections of TAK-771 after the end of the previous study. The participants will be treated with TAK-771 for totally 3 years. There will be many clinic visits. The number of visits will depend on the infusion cycles of study drug.

Outcome Measures
Primary Outcomes (2)
Percentage of Participants with Treatment-Emergent Adverse Events (TEAEs)
TEAEs are defined as AEs with onset after date-time of first dose of investigational drug or medical conditions present prior to the start of investigational drug but increased in severity or relationship after date-time of first dose of investigational drug.
Up to 3 years
Percentage of Participants who Develop Anti-rHuPH20 Binding Antibody Titers of Greater Than or Equal to 1:160 and who Develop Neutralizing Antibodies to rHuPH20
Up to 3 years
Study Arms (1)
TAK-771
EXPERIMENTALTAK-771 includes Immune Globulin Infusion (IGI) 10% and Recombinant Human Hyaluronidase (rHuPH20). Participants will receive SC infusion of rHuPH20 solution at a dose of 80 U/g IgG first, followed by SC infusion of 10% IGI within 10 minutes of completion of the infusion of rHuPH20 solution.
Interventions
Immune Globulin Infusion (IGI) 10% and Recombinant Human Hyaluronidase (rHuPH20)
