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
