This clinical trial is designed to test the safety and tolerability of injecting ANPD001 cells that will mature into dopamine-producing cells into the brain of participants with Parkinson Disease. All participants will have ANPD001 cells manufactured from their own previously collected cells.

Official Title

Phase 1/2a Dose Escalation Study of ANPD001 in Sporadic Parkinson Disease


Participants will undergo a surgical implantation of cells that will mature into dopamine-producing neurons under general anesthesia into a part of the brain where dopamine production is decreased in patients with Parkinson Disease. The effect on Parkinson Disease symptoms, safety and tolerability, and cell survival are assessed for 5 years post-transplant (with MRI and PET imaging scans of the brain). Safety and tolerability are assessed annually for an additional 10 years via telephone call (total follow-up of 15 years)
