简要总结
The purpose of this study is to determine the safety and efficacy of AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain. This study involves the treatment of subjects with medically refractory Parkinson's disease (PD). The gene transfer product, a disabled virus with a gene called GAD, will be infused into the STN bilaterally using stereotactic surgical techniques. The overall goal of this approach is to normalize the activity of the STN and reduce the motor symptoms of PD.
Because the change in UPDRS demonstrated a positive outcome, the sham surgery subjects from the blinded portion of the study will be invited to crossover into the Open-label Arm portion of the study. The Open-label Arm will further evaluate the safety and efficacy of AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain.
