Interventions/Control_1

Under general anesthesia using a stereotactic brain surgery system, human iPSC-derived dopaminergic progenitors will be transplanted into the bilateral putamen. For the first 3 patients, approximately 2.4X10^6 cells will be delivered at each side. For the 4th and later patients, 4.2-5.4X10^6 cells will be transplanted at each side.
Immunosuppressant treatment will be started in the morning on the day of transplantation, continued until 52 weeks after transplantation, and then tapered off to zero over 12 weeks. In the early phase, the immunosuppressant is orally administered 0.03 to 0.15 mg/kg, twice a day, and the targeted blood concentration is within a range of 5-10 ng/mL as a trough value.
