Condition(s) studied

Investigational drug(s) / intervention(s)

Allogenic embryonic stem cellderived A9 dopamine progenitor cell (A9-DPC)_Low Dose: 1. IP Name : Allogenic embryonic stem cell-derived A9 dopamine progenitor cell (A9-DPC) 2. Main ingredients and quantities: A9-DPC -Low Dose : 7.0X10\^6 cells (Use 3.15X10\^6 cells of this) 3. Formulation: milky white cell suspension 4. Storage method: Refrigerated storage (5±3℃) 5. Expiration date: within 36 hours of manufacture 6. Frequency: single dosing 7. Method: The subject pierces a burr hole in the skull on the day of surgery. Then the cells are injected at a predetermined stem cell administration point of the putamen in the brain of the subject. One side is administered in three tracks per putamen (6 tracks total brain). Do the same for the other side.

Allogenic embryonic stem cellderived A9 dopamine progenitor cell (A9-DPC)_High Dose: 1. IP Name : Allogenic embryonic stem cell-derived A9 dopamine progenitor cell (A9-DPC) 2. Main ingredients and quantities: A9-DPC -High Dose : 1.4X10\^7 cells (Use 6.30X10\^6 cells of this) 3. Formulation: milky white cell suspension 4. Storage method: Refrigerated storage (5±3℃) 5. Expiration date: within 36 hours of manufacture 6. Frequency: single dosing 7. Method: The subject pierces a burr hole in the skull on the day of surgery. Then the cells are injected at a predetermined stem cell administration point of the putamen in the brain of the subject. One side is administered in three tracks per putamen (6 tracks total brain). Do the same for the other side.

Study summary

1. Long-term follow-up period: Approximately 72 months from the date of approval by the Institutional Review Board (IRB)( Study Period: From the A9-DPC treatment date of the first subject in SB-PD-001 Study\* up to 5 years after the A9-DPC treatment of the last subject )
2. Objectives: This study aims to evaluate the long-term safety of A9-DPC by following up on the occurrence of adverse event of special interest, (AESI)\* for 5 years from A9-DPC treatment date in subjects who have participated in SB-PD-001 Study and received A9-DPC. In addition, it will determine motor and non-motor symptoms over time following A9-DPC treatment, as measured by MDS-UPDRS.
3. Methods of the Long-term Follow-up : This is a single center, open-label, 5-year long-term follow-up to evaluate the long-term safety in subjects receiving A9-DPC in SB-PD-001 Study.

Among subjects who have received A9-DPC, those who have provided voluntary written informed consent for participation of the long-term follow-up will be included. The occurrence of AESIs is investigated for 5 years from A9-DPC treatment, and MDS-UPDRS will be conducted for the efficacy assessment if the study can be conducted.

To avoid any missing data about AESIs, a phone or site visit will be performed at least once yearly from the start of the follow-up.
