The Safety, Tolerability and Efficacy of NouvNeu001 for Parkinson's Disease

Phase 1
Recruiting
Conditions
Parkinson Disease
Interventions
Biological: Human Dopaminergic Progenitor Cells
Registration Number
NCT06167681
Lead Sponsor
iRegene Therapeutics Co., Ltd.
Brief 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.

Detailed 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.

Primary Outcome Measures
NameTimeMethod
Motor Function24 weeks post-transplant

Changes in Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part â…¢ score from baseline to 24 weeks post-transplant. MDS-UPDRS Part III assesses the motor signs of PD, a higher score indicates more severe symptoms of PD.

Safety and Tolerability24 weeks and 48 weeks post-transplant

Incidence and severity of adverse events (AEs) and serious adverse events (SAEs).

Secondary Outcome Measures
NameTimeMethod
The Motor Function and Non-motor Function48 weeks and 96 weeks post-transplant

Changes in MDS-UPDRS Part I-IV Score from baseline to 48 weeks and 96 weeks post-transplant. A higher score indicates more severe symptoms or worse health.

Continued Safety and Tolerability96 weeks and 5 years post-transplant

Incidence and severity of AEs and SAEs within 96 weeks and 5 years post-transplant.
