## Summary For Families

The goal is to collect real-world, practical experience with continuous subcutaneous foslevodopa/foscarbidopa for people with advanced Parkinson's who have troublesome motor fluctuations and off periods on oral levodopa. The work is a retrospective look at patients treated in routine care, and the medication consists of prodrugs that are converted into levodopa and carbidopa after infusion, delivering steady levodopa levels through a small pump to smooth on/off swings and often reduce the need for frequent oral levodopa doses. Eligible participants are adults 18 and older with levodopa-responsive idiopathic Parkinson's who were prescribed the LDp/CDp continuous subcutaneous infusion and enrolled in the AbbVie Patient Support Program.
