A Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of BIIB094 in Adults With Parkinson's Disease
A Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of BIIB094 in Adults With Parkinson's Disease
The primary objective of this study is to evaluate the safety and tolerability of single and
 multiple doses of BIIB094 administered via intrathecal (IT) injection to participants with
 Parkinson's Disease (PD). The secondary objective of this study is to evaluate the
 pharmacokinetic (PK) profile of BIIB094.The study is open for PD patients with verified
 presence or absence of variations in the leucine-rich repeated kinase 2 (LRRK2) gene, but
 also for patients without any verified PD-related genetic variant.
Key Inclusion Criteria:

 -  Ability to understand the purpose and risks of the study and provide signed and dated
 informed consent and authorization to use confidential health information in
 accordance with national and local participant privacy regulations.

 -  Diagnosed with PD in the last 7 years, without major motor fluctuations or dyskinesia
 that may interfere with study treatment and assessments in the opinion of the
 investigator after consultation with the Sponsor.

 -  Modified Hoehn and Yahr Stage ≤ 3.

 Key Exclusion Criteria:

 -  Montreal Cognitive Assessment (MoCA) score less than (<) 23, dementia, or other
 significant cognitive impairment that, in the opinion of the Investigator, would
 interfere with study evaluation.

 -  History of any brain surgery for PD or a history of focused ultrasound treatment at
 any time; or history of neuromodulation procedures.

 -  Transient ischemic attack or stroke or any unexplained loss of consciousness within 1
 year before Screening.

 -  History of unstable angina, myocardial infarction, chronic heart failure, or
 clinically significant conduction abnormalities within 1 year before Screening.

 -  Poorly controlled diabetes mellitus, as defined by having dosage adjustment of
 diabetic medication within 3 months before dosing (Day 1) or glycosylated hemoglobin
 value greater than or equal to (≥) 8 percent (%) at Screening.

 -  History or positive test result at Screening for human immunodeficiency virus.

 -  History or positive test result at Screening for hepatitis C virus antibody.
