Brief Summary:
This is a 44-week, randomized, placebo-controlled, double-blind, single-center, phase 1 clinical trial consisting of a dose-escalation Part A study in healthy participants, followed by a Part B in participants with Parkinson's disease with a selected doses from Part A.

Condition or disease Intervention/treatment Phase
Parkinson's Disease Parkinsonism Biological: UB-312 Biological: Placebo Phase 1

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.

Primary Outcome Measures :
  1. Frequency of Adverse Events [ Time Frame: 44 weeks ]
    Number of AEs will be assessed

  2. Immunogenicity of UB-312 as determined by anti-aSyn antibodies in blood and CSF [ Time Frame: Weeks 1, 2, 5, 6, 9, 13, 14, 17, 21, 29, 37 and 45 ]
    Immunogenicity will be measured by change from baseline of blood anti-aSyn antibody titers.

  3. Immunogenicity of UB-312 as determined by anti-aSyn antibodies in blood and CSF [ Time Frame: Weeks 1, 21 and 45 ]
    Immunogenicity will be measured by change from baseline of CSF anti-aSyn antibody titers
