Gene therapy slows Parkinson progression

Trial ID
NCT07216066
Official Title
First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single Ascending Doses of Intrathecally Administered ALN-SNCA in Participants With Early Parkinson's Disease
Goal
Gene therapy slows Parkinson progression
Phase
PHASE1
Status
RECRUITING
Sponsor
Regeneron Pharmaceuticals
Study Type
INTERVENTIONAL
Enrollment
46 participants
Conditions
Parkinsons Disease
Interventions
ALN-SNCA, Placebo

Plain-Language Summary

The goal is to test whether lowering production of alpha-synuclein in the central nervous system is safe and biologically active in people with early Parkinson's, since alpha-synuclein buildup is linked to disease progression. The approach gives single ascending intrathecal doses of ALN-SNCA into the cerebrospinal fluid; ALN-SNCA is an RNA-based drug designed to reduce SNCA (alpha-synuclein) production in brain cells, and it is studied for safety, drug levels, and biological effects rather than immediate symptom relief, so it does not directly replace or change how levodopa works. The trial is enrolling people aged 50 to 80 with Parkinson's diagnosed within the last 4 years, who are either not yet on dopaminergic meds or have been on a stable oral dopaminergic regimen for at least 3 months, and who can safely undergo lumbar puncture and brain MRI; people with major medical issues, prior gene/cell or surgical PD treatments, or bleeding risks are excluded.
