Study of UB-312 in Healthy Participants and Parkinson's Disease Patients
A Phase 1 Study to Evaluate the Safety, Tolerability, and Immunogenicity of UBITh® PD Immunotherapeutic Vaccine (UB-312) in Healthy Participants and Participants With Parkinson's Disease

Detailed Description
This is a first-in-human Phase 1 study to determine the safety, tolerability, and immunogenicity of UB-312 in healthy participants and in participants with Parkinson's disease (PD). UB-312 is a UBITh®-enhanced synthetic peptide-based vaccine and may provide an active immunotherapy option for treating synucleinopathies including the most prevalent form, PD.
The study consists of two parts. Part A of the study with healthy participants will consist of dose escalation and cohort staggering for up to seven planned dose levels or placebo. Part B of the study will consist of two cohorts of participants with Parkinson's disease (PD). Dosing for Part B will be based on safety, tolerability and immunogenicity from Part A. All eligible participants will be enrolled in a 44-week study consisting of 20 weeks of treatment and 24 weeks of follow-up.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Male or female aged 40 to 85 years old, inclusive at screening
- Expected to be able to undergo all study procedures
- Other inclusion criteria apply
For Part B only:
- A diagnosis of PD, confirmed by a neurologist
- Hoehn &Yahr Stage ≤ III at Screening

- History or evidence of an autoimmune disorder
- History of anergy.
- Participated/participating in any clinical trial with monoclonal antibodies or vaccines directed at aSyn
- Other exclusion criteria apply
For Part B only:
- Other known or suspected cause of Parkinsonism other than idiopathic PD
- History or evidence at Screening of PD-related freezing episodes, falls, or orthostatic hypotension
- Dopamine transporter single-photon emission computerized tomography scan (DaTscan) inconsistent with dopamine transporter deficit.
- Clinically significant neurological disease other than PD
