Indications
- treatment of patients with moderately advanced Parkinson's disease
Clinical significance
- AADC is deficient in putamen of patient with Parkinson's disease
- AADC converts convert levodopa to dopamine
Procedure
- adenovirus vector serotype-2 carrying cDNA encoding AADC
- coadministered bilaterally with gadoteridol into the putamen
- intraoperative MRI was used to visualize spread of the infusion
Clinical trials
- PD-1101 phase 1b trial
- well-tolerated & resulted in stable or improved motor function & quality of life across cohorts, & reduced PD medication requirements over 3 years[2]
