Trial of magnetic resonance-guided putaminal gene therapy for advanced Parkinson's disease.

ABSTRACT:

Objective

To investigate the safety and tolerability of convection-enhanced delivery of an adeno-associated virus, serotype-2 vector carrying glial cell line-derived neurotrophic factor into the bilateral putamina of PD patients.

Methods

Thirteen adult patients with advanced PD underwent adeno-associated virus, serotype-2 vector carrying glial cell line-derived neurotrophic factor and gadoteridol (surrogate MRI tracer) coinfusion (450 μL/hemisphere) at escalating doses: 9 × 10¹⁰ vg (n = 6); 3 × 10¹¹ vg (n = 6); and 9 × 10¹¹ vg (n = 1). Intraoperative MRI monitored infusion distribution. Patients underwent UPDRS assessment and [¹⁸ F]FDOPA-PET scanning preoperatively and 6 and 18 months postoperatively.

Results

Adeno-associate
