Overview
Brief Summary
This is a randomized, placebo-controlled, parallel group, patient-blind, single-center phase I clinical trial of repeated once every 4 weeks administration by subcutaneous injection of AFFITOPE® PD01A, adsorbed to aluminium oxide in 30 patients with PD-GBA over a treatment period of 8 weeks. Patients will be randomized in a 2:1 ratio to two different treatment groups: A) 75 µg AFFITOPE® PD01A, adsorbed to aluminium oxide and B) placebo (= 1 mg aluminium oxide).
Over a study duration of 52 weeks, each patient will receive 3 injections of AFFITOPE® PD01A or placebo during the participation in the clinical trial. Patients will either receive 75 µg AFFITOPE® PD01A adsorbed to 1 mg aluminium oxide or placebo (=1mg aluminium oxide). The treatment group consists of 20 PDGBA patients, the placebo group of 10 PDGBA patients. Male and female patients aged 40 to 80 years can participate in the trial.
AFF010 is part of the project MULTISYN funded by the European Commission (FP7-HEALTH-2013-INNOVATION-1 project; N° HEALTH-F4-2013-602646).

- •Individuals who present in Hoehn\&Yahr Stages I/II/III and fulfill the United Kingdom Parkinson's Disease Society Brain Bank Criteria
- •Confirmed carrier status for a heterozygous GBA mutation (PDGBA)-The result of the MRI scan of the patient's brain has to be consistent with the diagnosis of PD
- •Written informed consent signed and dated by the patient and, preferentially, the caregiver (caregiver is not mandatory)
- •Age between 40 and 80
- •In the investigator's opinion, does not have visual or auditory impairments that would reduce the patients' ability to complete study questionnaires or be unable to receive instructions for these

- •A potential participant treated with conventional PD therapies must be on stable doses for at least 3 months prior to Visit 1 and during the entire trial period
- •Accepted PD medications include the following: levodopa (alone or in combination with benserazide, carbidopa), catechol-O-methyltransferase (COMT) inhibitors (entacapone, tolcapone), amantadine, non-ergot dopamine agonists (pramipexol, ropinirol, rotigotine), monoamine oxidase-B (MAO-B) inhibitors (rasagiline, selegiline) and anticholinergic medication
- •A potential participant should be on stable doses of all medications he/she is taking because of consisting illnesses according to medical history (except PD therapies, these will be recorded separately) for at least 30 days prior to Visit 1 if considered relevant by the investigator
Exclusion Criteria
- •Pregnant women
- •Sexually active women of childbearing potential who are not using a medically accepted birth control method
- •Participation in another clinical trial within 3 months before Visit 1
- •History of questionable compliance to visit schedule; patients not expected to complete the clinical trial
- •Presence or history of allergy to components of the vaccine if considered relevant by the investigator
- •Contraindication for MRI imaging such as metallic implants (e.g. endoprosthesis, stents, cardiac pacemakers) which are not MR compatible at 3.0 Tesla with the given MR protocol, other foreign metal bodies (e.g. bullets, metal splinters, e.g.) or claustrophobia
- •Missing agreement to be informed about incident findings and consultation of a neuroradiologist
- •Contraindication for PET, that is, pregnancy and breast feeding.
- •Ongoing participation in other interventional studies or clinical trials using radiotracers
- •Dementia according to Diagnostic and Statistical Manual (DSM) IV criteria
