BOOST-PD A Naturalistic Study on IPX-203 for Parkinson's Disease
Recruiting now · Phase 4
Conditions studied: Parkinson Disease
In brief
The purpose of this study is to evaluate the effect of IPX203 (Crexont®) - the newest extended-release levodopa formulation - on the duration and quality of good on time, using a wearable device to monitor symptoms. 'Good on time' refers to a period (minutes to hours) when a patient experiences optimal symptom control due to effective medication and has better overall functioning without troublesome dyskinesias. The change in the duration and quality of on-time will be measured by a wearable device placed on your wrist called KinesiaU.

- Baseline MDS-UPDRS score in OFF-state is > 20
- Patient is being treated with a stable regimen of CD-LD for at least four weeks
- The minimum most frequent levodopa dosing is 100 mg if using IR CD-LD and 195mg if using Rytary; maximum levodopa dosing per day is 1200 mg if using IR CD-LD, 1000 mg if associated with a COMT inhibitor, and 2400 mg if using Rytary

- Currently on device-aided therapies for advanced PD
- Using controlled-release CD-LD apart from a single daily bedtime dose
- Using "on demand" therapy unless willing to stop it during the study period
- Have a diagnosis hypothesis of dopamine dysregulation syndrome or evidence of significant levodopa-related complications including orthostatic hypotension or psychosis
- History of dementia or MOCA score lower than 23
- Significant medical history might interfere significantly with study participation
