NCT05150340

Brief Summary

The main aim of the study is to check how much TAK-771 stays in their blood over time, side effect from the study treatment or TAK-771, how much TAK-771 participants can receive without getting side effects from it, and if TAK-771 improves symptoms of primary immunodeficiency diseases (PID). This will help the study sponsor (Takeda) to work out the best dose to give people in the future. The participants will be treated with TAK-771 for totally 27 or 30 weeks. Treatment period is consist of two periods called Epoch 1 and Epoch 2. In Epoch 1, different groups of participants will receive lower to higher doses of TAK-771 for 3 to 6 weeks. The study doctors will check for side effects from each dose of TAK-771. In Epoch 2, participants will receive TAK-771 once a 3 or 4 weeks until the end of 24 weeks. There will be many clinic visits. The number of visits will depend on the infusion cycles of study drug (every 3, or 4 weeks).

Study Arms (2)

Epoch 1: TAK-771 Ramp up Period

EXPERIMENTAL

TAK-771 included IGI 10% and Recombinant Human Hyaluronidase (rHuPH20). Participants received subcutaneous 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. The dose of 10% IGI was increased from 1/3 of full dose to full dose in 3 weeks for participants who received TAK-771 once every 3 weeks, or from 1/4 of full dose to full dose in 6 weeks for participants who received TAK-771 once every 4 weeks.

Drug: TAK-771

Epoch 2: TAK-771 Full Dose Treatment Period

EXPERIMENTAL

TAK-771 included Immune Globulin Infusion (IGI) 10% and Recombinant Human Hyaluronidase (rHuPH20). Participants received subcutaneous 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, every 3, or 4 weeks for up to Week 27 for participants with 4-Week dosing interval or Week 25 for participants with 3-Week dosing interval.

Drug: TAK-771
