Interventions
BBM-P002 is an AAV-based gene therapy that delivers a therapeutic gene cassette into putamen for the treatment of Parkinson's Disease
Eligibility Criteria
You may qualify if:
- Participants with a diagnosis of Parkinson's disease for ≥ 5 years.
- The Hoehn-Yahr staging meets the requirements during the OFF periods.
- The MDS-UPDRS Part III score met the requirements during the OFF periods. the levodopa challenge test was positive
- During the screening period, participants were required to take the same stable dose of dopamine-releasing drugs (such as levodopa) regularly
