What this trial studies

This phase I clinical study aims to evaluate the safety and efficacy of transplanting autologous induced neural stem cell-derived dopamine precursor cells into the brains of patients with Parkinson's Disease. The study involves reprogramming patients' peripheral blood mononuclear cells to create dopaminergic neural precursor cells, which are then injected into the striatum using stereotaxic techniques. Participants will be monitored for safety, tolerability, and improvements in Parkinson's symptoms over a period of up to 12 months post-transplantation.
