Study Description

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.

Condition or disease	Intervention/treatment	Phase
Parkinson's Disease	Biological: NPC transplantation; Drug: Levodopa	Phase 1; Phase 2

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.

Study Design

• Study Type: Interventional (Clinical Trial)
• Estimated Enrollment: 50 participants
• Allocation: Non-Randomized
• Intervention Model: Single Group Assignment
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: A Phase I/II, Open-Label Study to Assess the Safety and Efficacy of Striatum Transplantation of Human Embryonic Stem Cells-derived Neural Precursor Cells in Patients With Parkinson's Disease
• Estimated Study Start Date: May 2017
• Estimated Primary Completion Date: November 2018
• Estimated Study Completion Date: December 2020

Arms and Interventions

Arm	Intervention/treatment
Experimental: NPC transplantation; The patients will receive Levodopa combined with a regular neural precursor cell (NPC) transplantation	Biological: NPC transplantation; The cells are stereotactically implanted in the striatum.; Drug: Levodopa; Levodopa is used depending on the patient's condition
Experimental: HLA-matched NPC transplantation; The patients will receive Levodopa combined with a HLA-matched neural precursor cell (NPC) transplantation	Biological: NPC transplantation; The cells are stereotactically implanted in the striatum.; Drug: Levodopa; Levodopa is used depending on the patient's condition
Experimental: HLA-non-matched NPC transplantation; The patients will receive Levodopa combined with a HLA-non-matched neural precursor cell (NPC) transplantation	Biological: NPC transplantation; The cells are stereotactically implanted in the striatum.; Drug: Levodopa; Levodopa is used depending on the patient's condition

Outcome Measures

Primary Outcome Measures :

1. Incidence of treatment-emergent adverse events (TEAEs), severe TEAEs as assessed by head MRI and blood examination [ Time Frame: 6 months ]
   Number of subjects with adverse events such as the evidence of graft failure or rejection

Secondary Outcome Measures :

1. Change in Unified Parkinson's Disease Rating Scale (UPDRS) score from baseline [ Time Frame: Baseline and 12 months ]
   The 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.
2. Change in DATscan from baseline [ Time Frame: Baseline and 12 months ]
   DATscan 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).
3. Change in Hoehn and Yahr Stage from baseline [ Time Frame: Baseline and 12 months ]
   The 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.
