            | Summary | 
            This clinical trial is designed to evaluate the safety, tolerability and preliminary efficacy of a single injection of NouvNeu001 (Human Dopaminergic Progenitor Cells Injection) in patients with Parkinson's disease. | 
        
                                
            | Description | 
            This is a multi-center, single arm, and open label trial. The NouvNeu001 will be transplanted into bilateral putamen/striatum using stereotactic neurosurgery. Subjects will take immunosuppressants to prevent potential immune rejection for 24 to 36 weeks. |
