Phase 1/2a Study of ANPD001 in Parkinson Disease

Phase 1
Conditions
Parkinson Disease
Interventions
Device: Custom Device
Registration Number
NCT06344026
Lead Sponsor
Aspen Neuroscience
Brief Summary

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.

Detailed Description

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)

Primary Outcome Measures
NameTimeMethod
Incidence and severity of treatment emergent adverse events (Safety and Tolerability)1 year (primary follow up)

incidence and severity of treatment emergent adverse events (TEAE) and serious adverse events (SAE)

Secondary Outcome Measures
NameTimeMethod
"ON" time without troublesome dyskinesia1 year (primary follow up) and 5 years (long term follow up)
Incidence and severity of treatment emergent adverse events during long term follow-up (Continued Safety and Tolerability)14 years of long term follow up (4 years in-person visits and 10 additional years follow up via telephone call)
Post-injection change in Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II (Activities of Daily Living - ADL) and Part III (motor score) in the ON state (total score and scores for Parts I-IV)1 year (primary follow up) and 5 years (long term follow up)

Part II score range is 0 to 52 with 0 being normal and 30 and above being severe

Post-injection change in the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III score in the practically defined OFF state1 year (primary follow up) and 5 years (long term follow up)

Part III score range is 0 to 132 with 0 being normal and 59 and above being severe

Post-injection change in the 18F-DOPA uptake in the putamen1 year (primary follow up) and 5 years (long term follow up)

Post-injection change in the 18-fluorodopa uptake in the putamen from baseline via positron emission tomography (PET)
