Safety and Pharmacodynamic Effects of BIIB122 in Participants With LRRK2-Associated Parkinson's Disease (LRRK2-PD)
Purpose
This Phase 2a, multicenter, randomized, 12-week double-blind, placebo-controlled, parallel-group study, followed by an OLE, is designed to evaluate the safety, tolerability, and pharmacodynamic effects of BIIB122 in participants with LRRK2-PD. LRRK2-PD is defined as Parkinson's Disease (PD) in individuals who are heterozygous or homozygous carriers of a pathogenic LRRK2 variant that increases LRRK2 kinase activity.
Condition
- Parkinson Disease
Eligibility
- Eligible Ages
- Over 30 Years
- Eligible Genders
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- For heterozygous pathogenic LRRK2 mutation carriers: ≥ 30 to ≤ 80 years - For homozygous pathogenic LRRK2 mutation carriers: ≥ 30 years - Have screening genetic test results verifying the presence of a pathogenic LRRK2 variant. - Have a clinical diagnosis of PD meeting the Movement Disorder Society Clinical Diagnostic Criteria.
Exclusion Criteria
- Have a history of any clinically significant neurological disorder other than PD, including, but not limited to, stroke and dementia, in the opinion of the investigator, within 5 years of the screening visit. - Have clinical evidence of atypical parkinsonism (eg, multiple-system atrophy or progressive supranuclear palsy) or evidence of drug-induced parkinsonism. - Have previously participated or are currently participating in the BIIB122 LUMA study (Study 283PD201). - Have previously participated or are currently participating in a gene therapy study for PD. - Have a history of brain surgical intervention for PD (eg, deep-brain stimulation, pallidotomy). - Have any physical condition that may confound the motor assessment (MDS-UPDRS) over time (eg, severe arthritis, severe dyskinesias, traumatic injuries with permanent physical disability). - Abnormal vitals including Blood Pressure, Heart Rate, or Body Temperature - Have abnormal PFT results at screening Note: Other protocol defined Inclusion/Exclusion criteria may apply
