Brief Summary:
AFF008E is set-up to assess the long term effects of the 4 PD01A vaccinations that have been applied during AFF008 with regard to safety as well as immunological-, radiological and clinical activity. Accordingly, during AFF008E, no further vaccine dose will be applied. Instead, patients who were participating in AFF008 will be assessed for another 52 weeks at the occasion of 4 quarterly visits. This is offered to patients who received PD01A vaccinations but also to the patients who served as controls in AFF008. Thus, AFF008E will ensure standardized and controlled management of individuals who have received PD01A as part of AFF008, the Phase I study analyzing for the first time in humans this first in class candidate.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Tolerability and Safety [ Time Frame: 52 weeks ]

    These will be based on the following parameters:

    • Withdrawal criteria (continuation decision) Number of patients who withdraw due to adverse events Reason for withdrawal
    • Occurrence of any serious adverse event possibly, probably or definitely related to the study vaccine at any time during the study.
    • Occurrence of any adverse events possibly, probably or definitely related to the study vaccine


Secondary Outcome Measures :
  1. Immunological and Clinical Efficacy [ Time Frame: 52 weeks ]

    Immunological parameters:

    -Titer of antibodies specific for the immunizing peptide, keyhole limpet hemocyanin (carrier protein), α-Synuclein, β-Synuclein as assessed by Enzyme-Linked Immunosorbent Assay

    Clinical efficacy variables:

    Motor symptoms:

    • Movement Disorder Society Unified Parkinson's Disease Rating Scale III
    • Investigator's Global Evaluation scale Non-motor symptoms
    • Parkinson's Disease Quality of Life-39 / Parkinson's Disease Non Motor Symptoms
    • Movement Disorder Society Unified Parkinson's Disease Rating Scale II
    • Cognitive scales
    • Smell identification test
    • Movement Disorder Society Unified Parkinson's Disease Rating Scale Ia (Caregiver-based assessment)
    • Geriatric Depression Scale Biomarker data
    • Change in Dopamine Transporter - Single Photon Emission Computed Tomography signal (compared to AFF008 results)
    • Assessment of change of volume of relevant brain regions (compared to AFF008 results)


Biospecimen Retention:   Samples With DNA
Analyzing patients' DNA (isolated out of whole blood) for polymorphisms in genes/regions like REP1 or alpha-synuclein to correlate results with the progression rate of the disease.
