Outcome Measures

Primary Outcomes (2)

  • Assessment of changes during the medication "off" time in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part III, in comparison with baseline values.

    Minimum score: 0; Maximum score: 132; Higher scores mean a worse outcome.

    Within 12 months post-transplantation

  • Incidence and severity of transplant-related adverse events.

    Within 12 months post-transplantation

Secondary Outcomes (10)

  • Assessment of changes in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part I, in comparison with baseline values.

    Within 12 months post-transplantation

  • Assessment of changes in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part II, in comparison with baseline values.

    Within 12 months post-transplantation

  • Assessment of changes in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part IV, in comparison with baseline values.

    Within 12 months post-transplantation

  • Assessment of changes during the medication "off" time in motor function by using Purdue Pegboard test and gait analyzer, in comparison with baseline values.

    Within 12 months post-transplantation

  • Assessment of changes from baseline in total daily OFF time (or ratio of OFF time to daytime waking hours) at 12 months post-surgery.

    Within 12 months post-transplantation

  • +5 more secondary outcomes

Study Arms (1)

Autologous induced neural stem cell-derived DA precursor cells

EXPERIMENTAL

The patients will receive transplantation of autologous induced neural stem cell-derived DA precursor cells.

Drug: Autologous induced neural stem cell-derived DA precursor cells

Interventions

The autologous induced neural stem cell-derived DA precursor cells will be stereotactically implanted into the striatum of PD patients.
