About this trial
This study is being done to test a new way of delivering AB-1005 into the brain. The goal is to make the procedure easier and quicker to perform, while providing similar amounts of drug to the part of the brain that needs treatment.
Technical (Stage 0) To test if the new delivery method (prefrontal surgical approach) can consistently deliver AB-1005 to the putamen using MRI monitoring.
Technical (Stage 1) To test if the new delivery method (PIA-based infusion) can consistently deliver AB-1005 to the putamen using brain imaging by MRI.
Technical (Stage 2) To confirm the new delivery method works without brain imaging by MRI, using standard operating room tools including brain imaging by CT.
Safety (Stage 1 and 2) To assess the safety and tolerability of the new delivery method for AB-1005 up to 6 months after surgery
