A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study and Open-Label Extension to Evaluate the Safety and Efficacy of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease (NEULARK)
Neuron23 Inc.
Summary
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 40-80 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.
Description
NEU-411-PD201 is a Phase 2, randomized, placebo-controlled, proof-of-concept study and open-label extension (OLE) in participants with early Parkinson's Disease (PD) who have LRRK2-driven PD as measured by an investigational companion diagnostic genetic test (CDx). The study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of NEU-411, an orally-administered, potent, selective, bioavailable, highly permeable, brain penetrant, small molecule inhibitor of LRRK2 activity as compared to placebo. After participants are screened for inclusion in the randomized, placebo-cont…
