Three gene transfer paradigms for Parkinson's disease have been explored: converting L-dopa into dopamine through AADC gene delivery in the putamen; synthesizing GABA through GAD gene delivery in the overactive subthalamic nucleus and providing neurotrophic support through neurturin gene delivery in the nigro-striatal pathway.

Previous studies in Parkinson's Disease (PD) models have shown promise with the use of recombinant adeno-associated virus serotype-2 (rAAV2)-neurturin (NRTN) [AAV2-NRTN] providing neuroprotection and behavioral improvements in preclinical models which subsequently resulted in several clinical studies in patients with PD.
