The study evaluated the long-term safety of two dosing regimens of ND0612, showing that continuous subcutaneous infusion of levodopa/carbidopa with ND0612 is generally safe, with infusion site reactions being the main adverse event. 56% of patients completed 12 months of treatment, with a reduced discontinuation rate after protocol revision.
Background Continuous, subcutaneous (SC) levodopa/carbidopa infusion with ND0612 is under development as a treatment for patients with Parkinson's disease (PD) and motor fluctuations. Objective Evaluate 1-year safety data. Methods BeyoND is an open-label study evaluating the long-term safety of two ND0612 dosing regimens. Results Of the 214 enrolled patients (24-hour SC infusion: n = 90; 16-hour SC infusion: n = 124), 120 (56%) completed 12 months of treatment. Leading causes for study discontinuation were consent withdrawal (19.6%) and adverse events (17.3%). Rates of discontinuation were reduced from 49% to 29% after a protocol revision and retraining. Systemic safety was typical for PD patients treated with levodopa/carbidopa. Most patients experienced infusion site reactions, particularly nodules (30.8%) and hematoma (25.2%), which were judged mostly mild to moderate and led to discontinuation in only 10.3% of the participants. Conclusions Subcutaneous levodopa/carbidopa continuous infusion with ND0612 is generally safe, with typical infusion site reactions for SC delivery as the main adverse event. (c) 2021 The Authors.
