Who can join

Age: 40 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects must be aged 40 to 85 years, inclusive, on the day of randomization.
• Meet criteria for a diagnosis of mild-to-moderate idiopathic PD according to the United Kingdom Parkinson's Disease Society Brain Bank criteria (Hughes et al 1992)
• PD should be stage 1 to 3 using the Hoehn and Yahr scale as modified (Goetz et al 2004).
• Subjects receiving medications for PD should have been on a stable dosing regimen of their medication(s) for ≥ 1 month before randomization, with no expectation of a need to change the medications or dosing regimen for the duration of the study, barring unforeseen circumstances. (For subjects who are not currently receiving medications to treat PD, there should be no expectation of a need to initiate these for the duration of the study).
• Subjects must have a body weight of 45 to 120 kg, inclusive, and a body mass index of 18 to 34 kg/m2, inclusive at screening and at check-in for the first infusion.
• Subjects may be male or female. Female subjects must of non-childbearing potential (postmenopausal and/or surgically sterile.
• Postmenopausal women must have had ≥ 12 months of spontaneous amenorrhea (with a follicle-stimulating hormone [FSH] concentration ≥ 26 mIU/mL in women ≤ 60 years of age; women > 60 years of age do not require an FSH test) and must have had a negative serum pregnancy test result at screening.
• Surgically sterile women are defined as those who have had a hysterectomy, bilateral ovariectomy (oophorectomy), salpingectomy, or bilateral tubal ligation. Women who are surgically sterile must provide documentation of the procedure by an operative report, ultrasound, or other verifiable medical documentation.
• Men who are biologically capable of fathering children must agree and commit to use an adequate form of double-barrier contraception for the duration of the treatment period and for 5 half lives (100 days) after the last administration of study intervention. A male subject is considered capable of fathering children even if his sexual partner is sterile or using contraceptives.
• Men who are biologically capable of fathering children must also agree to refrain from sperm donation for the duration of the treatment period and for 5 half-lives or 90 days (whichever is longer) after the last administration of study intervention.
• Subjects must, in the investigator's opinion, understand the nature of the study and must provide signed and dated written informed consent before the conduct of any study-related procedures.
• Subjects must, in the opinion of the investigator, be able to participate in all scheduled evaluations, likely to be compliant, and likely to complete all required tests, including magnetic resonance imaging (MRI) brain scans and lumbar punctures (LPs). (Note: The investigator should assess the physical and functional needs of the subject at screening, as participation in the study may be contingent upon the availability and willingness of a caregiver to attend with the subject at all study visits.)
• Subjects must be able to read, write, and speak fluently in English and/or Spanish.
• Subjects must agree not to post any personal medical data related to the study or information related to the study on any website or social media site (eg, Facebook, Twitter, Instagram, etc) until the study has been completed.
• Subjects must have a MoCA total score of ≥ 24.

You may not qualify if…

• In the opinion of the investigator, a recent clinically significant illness (other than PD), infection, medical/surgical procedure, or significant trauma within 30 days prior to screening, or between screening and randomization, that is likely to deteriorate, compromise the subject's safety or ability to complete the study, or compromise the interpretation of the study results (Note: a history of coronavirus disease 2019 [COVID 19] infection with unresolved medical sequelae would be considered exclusionary.)
• Presence of a serious or unstable clinically significant illness, including hepatic, renal, gastroenterologic, respiratory, cardiovascular, endocrinologic, immunologic or autoimmune disease (eg, multiple sclerosis), hematologic or other major disease, which, in the judgment of the investigator, is poorly controlled or otherwise likely to deteriorate, compromise the subject's safety or ability to complete the study, or compromise the interpretation of the study results
• Significant neurological disease affecting the CNS (other than PD) that, in the opinion of the investigator, may affect motor function or the ability to complete the study, including but not limited to progressive supranuclear palsy, multiple system atrophy (MSA; including MSA-P and MSA-C or other MSA terminology: striatonigral degeneration, olivopontocerebellar atrophy or autonomic failure), postencephalitic parkinsonism, metabolic diseases with parkinsonian signs and symptoms (eg, Wilson disease, manganese exposure) or other secondary forms of Parkinsonism, and ischemic or traumatic brain injury (including multiple episodes of head trauma, or head trauma resulting in protracted loss of consciousness within the 5 years prior to screening or between screening and randomization)
• Brain MRI scan that shows clinically significant evidence of malignant, ischemic, demyelinating, structural, or degenerative brain disease or has findings that compromise the safety of LP
• Has undergone surgery for the treatment of PD (eg, pallidotomy, deep brain stimulation, fetal tissue transplantation) or has undergone any other brain surgery at any time, even for non-PD conditions
• History of epilepsy or seizures, except febrile childhood seizures
• History of transient ischemic attack or stroke or any unexplained loss of consciousness within 1 year prior to screening or between screening and randomization
• Presence of any psychiatric disorder according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-V; APA 2013) or symptom if, in the judgment of the investigator, the psychiatric disorder or symptom is likely to confound interpretation of the study results, affect motor function assessment, or affect the subject's ability to complete the study
• A diagnosis of intellectual disability (intellectual developmental disorder) or mental retardation, or significant inherited cognitive impairment
• Suicidality, represented by answering "yes" to Question 4 or Question 5 on the C SSRS, indicating active suicidal ideation with any intent to act, during the subject's lifetime, as assessed at screening, or between screening and randomization
• Suicidal behavior such that a determination of "yes" is made on the Suicidal Behavior section of the C SSRS for "Actual Attempt," "Interrupted Attempt," "Aborted Attempt," or "Preparatory Acts or Behavior," during the subject's lifetime, as assessed at screening, or between screening and randomization
• History of alcohol or drug abuse or dependence (except nicotine dependence), as defined by the DSM-V, within 2 years prior to screening or between screening and randomization
• Within 1 year prior to screening, any of the following: myocardial infarction; hospitalization for congestive heart failure; hospitalization for, or symptoms of unstable angina; unexplained syncope
• Moderate or severe congestive heart failure, or known ejection fraction < 40%
• Known significant structural heart disease (eg, significant valvular disease, hypertrophic cardiomyopathy) that is considered likely to lead to a deterioration of cardiac function over the course of the study
• History of cancer within 5 years prior to screening or between screening and randomization, with the exception of non-metastatic basal and/or squamous cell carcinoma of the skin
• History of allergy/hypersensitivity to immunizations or immunoglobulins
• Any condition that, in the opinion of the investigator or medical monitor, makes the subject unsuitable for the study
• Requires treatment with another monoclonal antibody
• Use of any investigational medicine, device, or biologic within 3 months or 5 half-lives of that intervention (whichever is longer) prior to screening
• Previous allogeneic bone marrow or stem cell transplant
• Use of typical or atypical antipsychotic medication, or other medication with dopamine antagonist properties (eg, metoclopramide, domperidone), within 6 months prior to randomization
• Use of immunosuppressive medication within 6 months prior to randomization. (Note: Inhaled and topical corticosteroids are permitted. Low-dose systemic corticosteroids [< 10 mg per day prednisone or equivalent], for autoimmune disease that is considered to be quiescent, in remission, or otherwise well controlled are permitted). Other immunosuppressive drugs and biologics are contraindicated.
• Received non-leukocyte depleted whole blood transfusion within 6 months prior to screening
• Received any commercially available vaccine within 30 days prior to randomization. (Note: for COVID-19 vaccines authorized by the FDA for emergency use, this time frame applies from last vaccination or booster dose, whichever is required to consider vaccination complete in line with applicable guidance.)
