Clinical Trial Summary

The primary objective of this study is to evaluate the safety and tolerability of a range of single and 13 repeated doses of BIIB054, administered as intravenous (IV) infusion, in Japanese participants with Parkinson's disease (PD). The secondary objectives are to evaluate the immunogenicity, and serum pharmacokinetics (PK) profile of BIIB054 after single and multiple dose administration.

Eligibility

Key Inclusion Criteria:

• Diagnosed with PD within a maximum of 3 years prior to screening.

• Has not received levodopa or any other treatment for PD, herein referred to as symptomatic PD medication (including but, not limited to, dopamine agonists, amantadine, anticholinergics, monoamine oxidase type B (MAO-B) inhibitors, or safinamide) for at least 12 weeks prior to Day 1. Maximum total duration of prior PD regimens should not exceed 30 days.

• Screening value for hemoglobin less than (<)12 gram per deciliter (g/dL) for men or <11 g/dL for women.

• Montreal Cognitive Assessment (MoCA) score <23 or other significant cognitive impairment or clinical dementia.

• History of any brain surgery for PD.

• Participation in any passive or active immunotherapy targeting alpha-synuclein or other PD-related protein.

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, or is a medically important event.
