Conditions

Parkinson's Disease

Brief summary

This study will evaluate the safety and efficacy of intracerebral transplantation of human embryonic stem cells-derived neural precursor cells in patients with Parkinson's Disease.

Detailed description

This study is a Phase I/II, open-label, non randomized clinical trial. The study will enroll 50 patients for cell injection, administering a single dose of neural precursor cells by stereotaxic intra-striatal injection.

Interventions

BIOLOGICALNPC transplantation

The cells are stereotactically implanted in the striatum.

DRUGLevodopa

Levodopa is used depending on the patient's condition

Design outcomes

Primary

MeasureTime frameDescription
Incidence of treatment-emergent adverse events (TEAEs), severe TEAEs as assessed by head MRI and blood examination6 monthsNumber of subjects with adverse events such as the evidence of graft failure or rejection

Secondary

MeasureTime frameDescription
Change in Unified Parkinson's Disease Rating Scale (UPDRS) score from baselineBaseline and 12 monthsThe total Unified Parkinson's Disease Rating Scale (UPDRS) score is derived from Part I (Mentation, Behavior and Mood), Part II (Activities of Daily Living) and Part III (Motor Examination). Part I assesses 4 functions; Part II assesses 13 activities of daily living; Part III assesses 14 motor symptoms. Each item is rated on a scale from 0 (normal) to 4 (severe). The minimum total score possible is 0 and the maximum total score possible is 176. Each subject was independently rated by two observers at each study visit and a mean score was calculated for analysis.
Change in DATscan from baselineBaseline and 12 monthsDATscan is an imaging technology that uses small amounts of a radioactive drug to help determine how much dopamine is available in a person's brain.Its principle is based on using of radiopharmaceutical, which bind to dopamine transporters (DAT).
Change in Hoehn and Yahr Stage from baselineBaseline and 12 monthsThe Hoehn and Yahr scale is a commonly used system for describing how the symptoms of Parkinson's disease progress mainly by observing balance and walk.
