What this trial studies

This observational study follows about 103 adults with advanced, levodopa-responsive Parkinson's disease who are prescribed subcutaneous foslevodopa/foscarbidopa during routine clinical care across roughly 20 sites in Spain. Participants will receive the medication as prescribed by their treating physicians and be followed for up to 12 weeks with clinic visits that align with usual care. Eligible participants must be age 18 or older and have an MMSE score ≥24, and those with treated moderate-to-severe obstructive sleep apnea may be included if compliant with CPAP. The study collects information on sleep disturbances without adding experimental procedures beyond standard treatment.

Who should consider this trial

Good fit: Ideal candidates are adults with advanced, levodopa-responsive Parkinson's disease who have been prescribed subcutaneous foslevodopa/foscarbidopa by their clinician, can complete study procedures (MMSE ≥24), and can attend clinic visits in the study regions in Spain.

Not a fit: Patients who are not prescribed the drug, have significant cognitive impairment (MMSE <24), have untreated severe sleep apnea, or cannot attend participating Spanish clinics are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could show that subcutaneous foslevodopa/foscarbidopa reduces sleep disturbances and improves nighttime sleep and daytime function for people with advanced Parkinson's disease.

How similar studies have performed: Previous clinical programs of subcutaneous levodopa/carbidopa formulations have shown benefits for motor fluctuations, but direct evidence specifically demonstrating sleep improvement is limited.
