Abstract [en]

Background: Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) can effectively manage motor and non-motor complications in advanced Parkinson's disease (PD). Healthcare costs, quality of life (QoL), effectiveness, and tolerability were assessed in routine care treatment with LCIG. Methods: The seventy-seven patients enrolled in this prospective, open-label, 3-year study in routine medical care were LCIG-naive (N = 37), or had previous LCIG treatment for <2 (N = 22), or >= 2 (N = 18) years. Healthcare costs were collected monthly. PD symptoms and QoL were assessed with the Unified Parkinson's Disease Rating Scale (UPDRS), 39-item Parkinson's Disease Questionnaire (PDQ-39), and EuroQoL 5-Dimension Visual Analog Scale (EQ-5D VAS); LCIG dose, safety, and tolerability were monitored. Results: Mean monthly costs per patient ( 8226 5952) were similar across cohorts, remained steady during 3-year follow-up, and increased with PD severity and QoL impairment. In LCIG-naive patients, significant improvements compared to baseline were observed on the UPDRS total score and PDQ-39 summary index score through 18 months (n = 24; UPDRS, p = 0.033; PDQ-39, p = 0.049). Symptom control was maintained during 3-year follow-up in LCIG-experienced cohorts. Small changes in mean daily LCIG dose were observed. Adverse events were common and generally related to the device, procedure, levodopa, or laboratory evaluations. Conclusions: Costs in LCIG-treated patients were stable over 3 years. LCIG treatment led to significant improvements in motor function and QoL over 18 months in LCIG-naive patients and no worsening was observed in LCIG-experienced patients over 3 years despite natural PD progression over time. The longterm safety was consistent with the established LCIG profile.
