BackgroundAs Parkinson's disease (PD) progresses, managing symptoms becomes increasingly difficult. Foslevodopa/foscarbidopa (LDp/CDp), a 24-hour/day continuous subcutaneous infusion of levodopa/carbidopa (LD/CD) prodrugs, improves motor complications. The feasibility and sustainability of LDp/CDp monotherapy warrants investigation.ObjectiveThe aim was to report the efficacy and safety of LDp/CDp monotherapy and combination therapy.MethodsThis post hoc analysis assessed patients with PD and ≥2.5 "Off" hours/day receiving LDp/CDp monotherapy or combination therapy in 3 trials: a 12-week randomized active-controlled trial (RCT) comparing LDp/CDp with oral immediate-release LD/CD (NCT04380142), a 52-week open-label trial of LDp/CDp (NCT03781167), and its 96-week open-label extension study (OLE; NCT04379050). Monotherapy was defined as receiving LDp/CDp without concomitant PD medications; combination therapy was defined as receiving LDp/CDp with other PD medications.ResultsIn the RCT, 74 of 141 patients received LDp/CDp. The 52-week trial enrolled 244 patients; 129 entered the OLE. Of LDp/CDp-treated patients, 19 of 74 (25.7%) in the RCT, 49 of 244 (20.1%) in the 52-week trial, and 46 of 129 (35.7%) in the OLE received monotherapy. In the RCT, mean (standard deviation) change from baseline to week 12 in "Off" time was -4.5 (4.4) and -3.0 (3.5) hours for monotherapy and combination therapy, respectively; +4.1 (3.7) and +3.1 (3.6) hours for "On" time without troublesome dyskinesia; and +4.0 (3.6) and +4.0 (3.9) hours for "On" time without dyskinesia. Efficacy was similar in open-label trials. Improvements in the Movement Disorder Society-Unified Parkinson's Disease Rating Scale Part II, 39-item Parkinson's Disease Questionnaire, Parkinson's Disease Sleep Scale-2 scores, and overall safety were comparable between monotherapy and combination therapy groups.ConclusionsLDp/CDp monotherapy treatment may be suitable for up to 96 weeks.
