A Study to Evaluate the Safety and Tolerability of ABBV-951 in Subjects With Parkinson's Disease (PD)

Purpose

The purpose of this study was to assess the safety and tolerability of ABBV-951 (Foslevodopa/Foscarbidopa) in participants with Parkinson's disease (PD). This was a single-arm study with preplanned analyses conducted by dose subgroup (Low Dose or High Dose) based on the modal total daily dose (most frequent dose) over the treatment period.

Experimental
ABBV-951 Low Dose Subgroup
After a 4-week Optimization Period, participants continued receiving ABBV-951 by continuous subcutaneous infusion (CSCI) during the 48-week Maintenance Period. Participants whose modal total daily dose (most frequent dose) over the entire study was < 2530 mg of Foslevodopa/day were analyzed as the Low Dose Subgroup.

ABBV-951 High Dose Subgroup
After a 4-week Optimization Period, participants continued receiving ABBV-951 by continuous subcutaneous infusion (CSCI) during the 48-week Maintenance Period. Participants whose modal total daily dose (most frequent dose) over the entire study was ≥ 2530 mg of Foslevodopa/day were analyzed as the High Dose Subgroup.
