Is this trial a fit for you?

Likely a good fit

Adults 18–64 with levodopa-responsive idiopathic Parkinson's disease, motor fluctuations for ≤3 years, Hoehn and Yahr stage <3 on medication, and considered eligible for foslevodopa/foscarbidopa by their clinician are ideal candidates.

Probably not a fit

Patients with prior device-aided therapy, dementia (MMSE <24), contraindications per the local drug label, or those outside the age or motor-fluctuation windows are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, observational follow-up of about 125 adults who are prescribed subcutaneous foslevodopa/foscarbidopa during usual care across roughly 20 sites in Germany. Participants who meet criteria for early-stage advanced, levodopa-responsive Parkinson's disease will be followed for up to 12 months with regular clinic visits and data collection tied to routine care. Treatment is given as prescribed by the participant's clinician, with no experimental intervention or additional burden required beyond standard visits. The study aims to capture real-world effectiveness and tolerability in a defined early-advanced patient group rather than to test efficacy in a controlled trial.

Why it matters

Potential benefit: If successful, the study could provide real-world evidence on how well foslevodopa/foscarbidopa controls motor fluctuations and functions in everyday clinical practice for this patient group.

How similar studies have gone: Randomized trials have demonstrated efficacy of foslevodopa/foscarbidopa products, but prospective real-world data specifically in early-stage advanced patients are more limited.
