A Phase 2 Study of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease
NCT06680830
Recruiting
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 50-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway. Participants will: • Take NEU-411 or placebo every day for 52 weeks
