The Safety, Tolerability and Preliminary Efficacy of NouvNeu001 for Early-onset Parkinson's Disease

November 4, 2024 updated by: iRegene Therapeutics Co., Ltd.

A Phase I Study to Assess the Safety, Tolerability and Preliminary Efficacy of NouvNeu001 Injection in the Treatment of Early-onset Parkinson's Disease

The goal of this clinical trial is to learn about the safety of NouvNeu001 injection in Early-onset Parkinson's Disease (EOPD) patients. It will also learn about the effects of NouvNeu001 treatment. The main questions it aims to answer are:

What medical problems do participants have when transplanting NouvNeu001 into bilateral putamen using stereotactic neurosurgery? Does injection of NouvNeu001 improve the motor function and non-motor function in participants?

Participants will:

Be injectioned the NouvNeu001 into bilateral putamen using stereotactic neurosurgery.

Take immunosuppressants to prevent potential immune rejection for 24 to 36 weeks.
