Long-term effectiveness of a new Parkinson's medication in routine care

This study is watching how well LECIGON® (levodopa-entacapone-carbidopa intestinal gel) works for people with advanced Parkinson's disease who recently switched to this medication from another similar treatment. Researchers will collect information from real-world clinical visits to see if the medication reduces the number of hours per day when symptoms are not controlled. This is not a trial where you take a new experimental drug — instead, doctors are simply tracking your progress on a medication that's already been approved and that your doctor has decided is right for you.

Advanced Parkinson's disease causes long stretches of time when medications don't work well enough, leaving patients with uncontrolled movement symptoms. This study exists to understand how effective this newer medication is at reducing those 'off' periods when people switch from an older treatment in everyday clinical practice.
