Study Summary

The objective of this clinical trial was to evaluate the safety and tolerability of adeno-associated virus (AAV)-mediated delivery of glutamic acid decarboxylase (GAD) gene transfer into the subthalamic nuclei (STN) of participants with Parkinson's Disease.

Primary Outcome

The primary outcome measure is the safety of treatment with AAV-GAD, assessed by the absence of IMP-related treatment-emergent adverse events.

Interventions

  • PROCEDURE Sham Surgery
  • GENETIC AAV-GAD Low Dose
  • GENETIC AAV-GAD High Dose
