Restore dopamine to improve movement

Trial ID
NCT06753331
Official Title
A Multicenter, Sham-controlled, Randomized Study to Evaluate the Safety, Tolerability, and Clinical Responses Following Stereotactic Intracranial Implantation of DSP-1083 Into Subjects With Parkinson's Disease
Goal
Restore dopamine to improve movement
Phase
PHASE1, PHASE2
Status
RECRUITING
Sponsor
Sumitomo Pharma America, Inc.
Study Type
INTERVENTIONAL
Enrollment
25 participants
Conditions
Parkinson's Disease
Interventions
DSP-1083 implantation, Sham surgery treatment

Plain-Language Summary

The goal is to test whether implanting DSP-1083 cells into movement-related brain areas can safely engraft and improve motor symptoms by restoring dopamine function in people whose Parkinson's is not well controlled on meds. The approach is stereotactic brain surgery to place a cell therapy product, with a randomized sham surgery control so researchers can compare safety and clinical responses; the implanted cells are intended to survive and replace or support dopamine-producing neurons while participants remain on their usual levodopa regimen so changes in medication response can be assessed. The trial is looking for adults 40 to 72 years old with a clinical PD diagnosis for at least 4 years, a clear levodopa response, suboptimal control despite stable levodopa-based therapy, moderate off-state disability, and no prior DBS, ablation, or other implanted brain therapies.
