Gene therapy trial hopes to ease Parkinson's symptoms
NCT ID NCT04167540
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This early-stage trial tests a single dose of a gene therapy called AAV2-GDNF, delivered directly into the brain, for people with Parkinson's disease. The main goal is to check safety in 11 adults aged 35-75. Researchers will also look at whether it improves motor symptoms.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
AAV2-GDNF (a gene therapy that delivers GDNF protein to brain cells)
What this could lead to
If safe and effective, this could point toward a new way to slow or improve motor symptoms in Parkinson's disease.
What could go wrong
This is a very early Phase 1 trial with only 11 people, focused on safety. It may not show clear benefit, and brain infusion carries risks like bleeding or infection.
