Summary

This study is looking at whether a gene therapy called AAV2-hAADC is safe and may help people with Parkinson's Disease.

AAV2-hAADC is intended to increase the levels of dopamine in your brain. It contains a virus called adeno-associated virus 2 (AAV2) that has been modified to carry the genetic code for an enzyme called Aromatic L-Amino Acid Decarboxylase, or AADC for short.

In this study, AAV2-hAADC is delivered to two parts of the brain called the putamen and the caudate. Increasing the amount of AADC gene in these parts of the brain converts more levodopa into dopamine, the chemical that is lacking in PD.

Conditions

  • Parkinson's Disease (PD)
  • Early Onset Parkinson Disease

AAV2-hAADC

The purpose of this study is to investigate AAV2-hAADC gene therapy (the study drug) for the treatment of moderately-advanced PD with motor fluctuations. AAV2-hAADC gene therapy works by using a modified virus called adeno-associated virus 2 (AAV2). This virus is naturally-occurring and not associated with any disease. The virus' DNA has been changed so that it can deliver the human enzyme called Aromatic L-Amino Acid Decarboxylase (AADC). This enzyme converts levodopa into dopamine. AAV2-hAADC can enter brain cells and transfer the copy of the AADC gene directly into these cells. Once the gene is inside the brain cells, those cells will make AADC. By increasing the levels of AADC, we aim to increase the levels of dopamine and improve the symptoms of PD. AAV2-hAADC will be delivered through a brain surgery to two parts of the brain called the putamen and the caudate. These parts of the brain are involved in PD. The goal of this study is to assess whether infusing AAV2-h
