NouvNeu001 for Parkinson's Disease

This study is testing a new treatment called NouvNeu001, which involves injecting human dopaminergic progenitor cells into specific areas of the brain, for people with Parkinson's disease. Researchers want to see if this treatment is safe, how well people tolerate it, and if it shows any early signs of helping. You might be able to join if you are between 30 and 75 years old and have had Parkinson's disease for 4 to 20 years, with a certain level of motor symptoms (H-Y staging 2.5-4.0 during "OFF" episodes). The main goals are to check for safety and how well people tolerate the treatment for up to 48 weeks after the injection. This study is currently recruiting a small number of participants (5 people).

Study design
This is an early-stage (Phase 1/2), single-arm study, meaning all 5 participants will receive the NouvNeu001 treatment. It is also open-label, so both you and the study team will know which treatment you are receiving.
What's involved
You would receive a single injection of NouvNeu001 into your brain and then take medications to prevent immune rejection for 24 to 36 weeks.
Compensation
Not stated in the trial record.
Follow-up
Your safety and tolerability will be checked at 24 weeks and 48 weeks after the injection.
