Official title
A Phase 2, Randomized, Double-blind, Sham Surgery-controlled Study of the Efficacy and Safety of Intraputaminal AAV2-GDNF in the Treatment of Adults With Moderate Stage Parkinson's Disease
Overview
The objective of this randomized, surgically controlled, double-blinded, Phase 2 study is to evaluate the safety and efficacy of AAV2-GDNF delivered to the putamen in subjects with moderate Parkinson's Disease.
Interventions
- Drug AAV2-GDNF gene therapy
Bilateral image-guided infusion of AAV2-GDNF into putamen, single dose - Procedure control surgery
Bilateral partial burr/twist holes without dural penetration
Primary outcome measures
- Change from baseline to Month 18 on PD Motor Diary [Time frame: 18 months]
