Evaluate the safety, tolerability, and efficacy of foslevodopa/foscarbidopa (LDP/CDP, ABBV-951) delivered 24-hour/day as a continuous subcutaneous infusion (CSCI) for 52 weeks in advanced Parkinson’s disease (aPD) patients in an outpatient setting.
As PD progresses, oral levodopa loses effectiveness and motor complications develop, requiring alternative therapies. LDP/CDP is a new soluble formulation of levodopa/carbidopa prodrugs delivered as a CSCI via an ambulatory pump. 
This Phase 3, open-label, single-arm study (NCT03781167) enrolled levodopa-responsive PD patients with a minimum of 2.5 hours of “Off” time/day. Assessments of systemic safety and local tolerability are the primary objective of this study. Secondary efficacy assessments include presence of morning akinesia, change from baseline in hours of “On” and “Off” time (PD diaries) and in ADL, sleep and quality of life (QoL) scores measured by MDS-UPDRS part II, PDSS-2, PDQ-39 and EQ-5D-5L. 
As of 30March2021, 223 patients (60.1% male, 83.4% white, mean age of 64 years) were enrolled across 56 sites. Treatment emergent adverse events (AEs) were reported in 206 patients (92.4%). The most common AEs were erythema, nodule, cellulitis, and edema at the infusion site. The majority of AEs were mild or moderate and resolved spontaneously. Significant improvements in motor fluctuations were observed as early as Week 1; at Week 26 the mean increase in "On" time without troublesome dyskinesia was 3.24 hours and the decrease in "Off" time was 2.94 hours. Both "Off" and "On" time with dyskinesia decreased in favor of “On” time without dyskinesia. Improvements were also observed for morning akinesia, sleep, ADL and QoL. 
LCD/CDP was well-tolerated; systemic and skin AEs were consistent with those of levodopa and of other medications for subcutaneous delivery, respectively. The individualized, 24-hour/day, CSCI of LCD/LDP significantly reduced motor complications, improved morning akinesia, sleep disturbances and QoL, providing a minimally invasive therapeutic alternative for aPD patients.
