Brief Summary:
This clinical trial is designed to test whether surgically injecting nerve cells that make dopamine into the brain of Parkinson's disease patients is safe, and to monitor for potential side effects.

Condition or disease Intervention/treatment Phase
Advanced Parkinson's Disease Biological: MSK-DA01 Device: MSK-DA01 Cell Delivery Device Phase 1

Detailed Description:
Subjects will undergo surgical transplantation of the dopamine-producing cells under general anesthesia into a part of the brain called the putamen. Subjects then take medicines to partially suppress their immune system (aimed to prevent the body from rejecting the cells) for 1 year. Safety, tolerability, evidence of cell survival (using MRI and PET scans of the brain), and effect on Parkinson's disease symptoms are assessed for 2 years post-transplant.

Arm Intervention/treatment
Experimental: MSK-DA01 Biological: MSK-DA01
MSK-DA01 is an experimental product derived from human embryonic stem cells. The stem cells were converted into brain cells that produce dopamine.

Device: MSK-DA01 Cell Delivery Device
A device that is used for injection of fluids into the brain will be used. Some minor modifications have been made to the device to allow delivery of MSK-DA01 cells.

Primary Outcome Measures :
  1. Safety and Tolerability [ Time Frame: Baseline to 1 Year Post-Transplant ]
    The incidence of Serious Adverse Events (SAEs) at 1 year post-transplant. or abnormal tissue overgrowth related to presence of transplanted cells;

Secondary Outcome Measures :
  1. Evidence of Cell Survival [ Time Frame: Baseline to 1 Year Post-Transplant and Baseline to 2 Years Post-Transplant ]
    Change in 18F-DOPA uptake using positron emission tomography (PET) from baseline to 1 and 2 years

  2. Changes in Motor Function [ Time Frame: Baseline to 1 Year Post-Transplant and Baseline to 2 Years Post-Transplant ]
    Changes in MDS-Unified Parkinson's Disease Rating Scale (UPDRS) motor sub-score in the "off" state from baseline to 2 years post-transplant.

  3. Changes in Waking Hours in "Off" State [ Time Frame: Baseline to 1 Year Post-Transplant and Baseline to 2 Years Post-Transplant ]
    Changes in number of waking hours in the "off" state from baseline to 2 years post-transplant.

  4. Continued Safety and Tolerability [ Time Frame: Baseline to 1 Year Post-Transplant and Baseline to 2 Years Post-Transplant ]
    Incidence of SAEs at 2 years post-transplant and incidence and type of AEs at 1 and 2 years post-transplant.
