© The Author(s) 2024.The Phase II trial of Anti-alpha-Synuclein Antibody in Early Parkinson’s Disease (PASADENA) is an ongoing double-blind, placebo-controlled trial evaluating the safety and efficacy of prasinezumab in early-stage Parkinson’s disease (PD). During the double-blind period, prasinezumab-treated individuals showed less progression of motor signs (Movement Disorders Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS–UPDRS) Part III) than placebo-treated individuals. We evaluated whether the effect of prasinezumab on motor progression, assessed as a change in MDS–UPDRS Part III score in the OFF and ON states, and MDS–UPDRS Part II score, was sustained for 4 years from the start of the trial. We compared participants enrolled in the PASADENA open-label extension study with those enrolled in an external comparator arm derived from the Parkinson’s Progression Markers Initiative observational study. The PASADENA delayed-start (n = 94) and early-start (n = 177) groups showed a slower decline (a smaller increase in score) in MDS–UPDRS Part III scores in the OFF state (delayed start, −51%; early start, −65%), ON state (delayed start, −94%; early start, −118%) and MDS–UPDRS Part II (delayed start, −48%; early start, −40%) than did the Parkinson’s Progression Markers Initiative external comparator (n = 303). This exploratory analysis, which requires confirmation in future studies, suggested that the effect of prasinezumab in slowing motor progression in PD may be sustained long term.
