ObjectiveTo evaluate the sustained real-world effectiveness and safety of catechol-O-methyltransferase (COMT) inhibitors added to levodopa in patients with Parkinson's disease (PD) presenting early motor fluctuations.MethodsREONPARK is an ongoing, multicenter, prospective observational study conducted in Spain. Adult patients with PD and end-of-dose motor fluctuations for ResultsA total of 143 patients were included (99.3% treated with opicapone), of whom 138, 131, and 89 patients completed the 3, 6, and 12 months of follow-up, respectively. Levodopa doses remained stable in most patients (73% at 12 months). Significant and sustained improvements were observed in MDS-UPDRS Parts III and IV scores, as well as the total MDS-UPDRS score over 12 months, with greater likelihood of Part IV improvement in patients receiving ConclusionsIn PD patients with early motor fluctuations, opicapone initiation was associated with sustained improvements in motor outcomes and reduced OFF time, and maintained the ON-time quality over 12 months, with stable levodopa dosing.
