PB - MMS M1 - DZNE-2022-01476 SP - 421 - 432 PY - 2022 AB - Aggregated α-synuclein plays an important role in the pathogenesis of Parkinson's disease. The monoclonal antibody prasinezumab, directed at aggregated α-synuclein, is being studied for its effect on Parkinson's disease.In this phase 2 trial, we randomly assigned participants with early-stage Parkinson's disease in a 1:1:1 ratio to receive intravenous placebo or prasinezumab at a dose of 1500 mg or 4500 mg every 4 weeks for 52 weeks. The primary end point was the change from baseline to week 52 in the sum of scores on parts I, II, and III of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS; range, 0 to 236, with higher scores indicating greater impairment). Secondary end points included the dopamine transporter levels in the putamen of the hemisphere ipsilateral to the clinically more affected side of the body, as measured by 123I-ioflupane single-photon-emission computed tomography (SPECT).A total of 316 participants were enrolled; 105 were assigned to receive placebo, 105 to receive 1500 mg of prasinezumab, and 106 to receive 4500 mg of prasinezumab. The baseline mean MDS-UPDRS scores were 32.0 in the placebo group, 31.5 in the 1500-mg group, and 30.8 in the 4500-mg group, and mean (±SE) changes from baseline to 52 weeks were 9.4±1.2 in the placebo group, 7.4±1.2 in the 1500-mg group (difference vs. placebo, -2.0; 80 KW - Antibodies, Monoclonal, Humanized: therapeutic use KW - Antiparkinson Agents: therapeutic use KW - Dopamine Plasma Membrane Transport Proteins: therapeutic use KW - Double-Blind Method KW - Humans KW - Parkinson Disease: drug therapy KW - Treatment Outcome KW - alpha-Synuclein: antagonists & inhibitors KW - Antibodies, Monoclonal, Humanized (NLM Chemicals) KW - Antiparkinson Agents (NLM Chemicals) KW - Dopamine Plasma Membrane Transport Proteins (NLM Chemicals) KW - alpha-Synuclein (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:35921451 DO - DOI:10.1056/NEJMoa2202867 UR - https://pub.dzne.de/record/165174 ER -
