Background Opicapone is an oral, once-daily, selective catechol-O-methyltransferase (COMT) inhibitor used as adjunctive treatment to carbidopa/levodopa (CD/LD) in patients with Parkinson’s disease (PD) experiencing “OFF” episodes. The aim of the OPTI-ON study was to evaluate “real-world” patient characteristics, treatment patterns, and safety/tolerability of opicapone use in the US.

Objective To describe patient-reported outcomes (PROs) from the Opicapone Treatment Initiation Open-Label Study (OPTI-ON).

Design/Methods OPTI-ON was a prospective, open-label, single-arm, multicenter, observational, longitudinal (6-month) study of patients with PD experiencing “OFF” episodes who were prescribed opicapone adjunctive to CD/LD. PROs including the Patient Global Impression of Severity in the “OFF” state (PGI-S OFF), Patient Global Impression of Change (PGI-C), Non-Motor Fluctuations PGI-S (NMFs PGI-S), and Medication Satisfaction Questionnaire (MSQ) were obtained at baseline (BL) and throughout follow-up.

Results Overall, 164 patients completed the study. On the PGI-S OFF, more patients rated their “OFF” time symptom severity as none or very mild at 3 months (21.2%) and 6 months (20.4%) compared to BL (10.3%). For the PGI-C, 29.8% and 23.5% of patients were much or very much improved at months 3 and 6, respectively. On the NMFs PGI-S, fewer patients scored markedly to most extremely affected with NMFs at 6 months (3.2%) compared to BL (11.9%). On the MSQ, 42.3% of patients were very or extremely satisfied with their opicapone treatment at 6 months versus 14.2% with their treatment regimen at BL.

Conclusions After 6 months of opicapone treatment, patients reported improvement on the PGI-S OFF and PGI-C, reduced NMF severity on the NMFs PGI-S, and increased satisfaction on the MSQ. In addition to decreasing the duration of “OFF” episodes as shown in Phase 3 clinical studies, these results suggest once-daily opicapone may improve the quality of “OFF” time, more effectively manage motor fluctuations and NMFs in PD, and increase patients’ satisfaction with their PD treatment regimen.
