Official title
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)
Overview
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.
Detailed 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-controlled portion of the study, approximately 150 participants will be randomized in a 1:1 allocation to NEU-411 30 mg once per day or placebo for a 52-week treatment period with a safety follow-up visit within 2 weeks after the last treatment visit. Eligible participants may enroll in the OLE and receive treatment for an additional 26 weeks.
Interventions

NEU-411, a potent, selective, orally bioavailable, highly permeable, brain penetrant, small molecule inhibitor of LRRK2 activity - Other Placebo
Orally-administered matched placebo
Primary outcome measures
- Change from baseline in the Roche digital biomarker score using the Roche Parkinson's Disease application (v3.0) compared to placebo [Time frame: From enrollment to the end of treatment at 52 weeks]
- Incidence of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) compared to placebo [Time frame: From enrollment to the end of study at 54 weeks]
Secondary outcome measures (1)

Eligibility criteria
Inclusion criteria
