Trial identifier NCT02270489, 2014-000567-40, AFFiRiS 009

Summary

This is a randomized controlled parallel Group phase I study to investigate the safety and immunological/ therapeutic activity of two new vaccines, AFFITOPE® PD01A and AFFITOPE® PD03A, given to patients with early Multiple System Atrophy (MSA).

In total 30 patients are planned to be enrolled in the study: 12 patients in each treatment arm who will receive either 75µg AFFITOPE® PD01A (with adjuvant) or 75µg AFFITOPE® PD03A (with adjuvant) and 6 patients in the control group who will receive the reference substance (Placebo). Over a study duration of 52 weeks, the study participants will receive 4 injections as basic immunization in a 4-weekly interval and 1 boost immunization 36 weeks after the first injection. Male and female patients aged 30 to 75 years can participate in the trial. 2 study sites in France (Bordeaux and Toulouse) will be involved.

AFF009 is part of the project SYMPATH funded by the European Commission (FP7-HEALTH-2013-INNOVATION-1 project; N° HEALTH-F4-2013-602999).

Eligibility Criteria

Male or female participants from 30 years up to 75 years old.

Inclusion Criteria: - Possible or probably MSA diagnosis (MSA-P or MSA-C) according to Gilman 2008 consensus criteria - Onset of MSA symptoms less than 4 years - Participants with an anticipated survival of at least 3 years in the opinion of the PI - Written informed consent obtained prior to study entry - MSA patient > 30 and < 75 years of age at time of study entry - Female patients of childbearing potential using a medically accepted contraceptive method - Stable medication for MSA symptoms (Levodopa, Dopamine agonists, Midodrine, Fludrocortisone, monoamine oxidase-B and Catechol-O-methyltransferase inhibitors; Antidepressants, Laxatives, NSAIDs or paracetamol as basic medication for pain in the musculoskeletal system) Exclusion Criteria: - Pregnant or lactating women - Sexually active women of childbearing potential not using a medically accepted birth control method - Patients with dementia (MOCA at Screening < 21) - Speech impairment as assessed by a score of ≥ 3 on UMSARS question 1 - Swallowing impairment as assessed by a score of ≥ 3 on UMSARS question 2 - Impairment in ambulation as assessed by a score of ≥ 3 on UMSARS question 7 - History or evidence of any other central nervous system disorder like stroke, angioma and other relevant neurological diseases - History of malignancy other than skin cancer during the last 5 years (if considered to be cured, patient might be included) - Active or passive vaccination 4 weeks before the first vaccination on Day 0 and during the main study period ending on Day 280. Emergency vaccinations are acceptable - Use of any other investigational or non-registered drug or vaccine in addition to the study vaccine during the entire study period - Subjects participating or have participated in another interventional clinical trial within 60 days prior to baseline - Blood donation within 4 weeks prior to first vaccination. - History of autoimmune diseases, severe hypersensitivity reactions and anaphylaxis, allergic bronchial asthma and severe allergic rhinoconjunctivitis - Known hypersensitivity or allergic reaction to one of the components of the vaccine - A family history of congenital or hereditary immunodeficiency - Administration of chronic (defined as more than 14 days) immunosuppressant or other immune-modifying drugs within six months before first vaccination and during the entire study period. For corticosteroids like prednisone or equivalent ≥ 0.05 mg/kg/day. Topical and inhaled steroids are allowed - Intake of non steroidal anti-inflammatory drugs (NSAIDs) or paracetamol more than the basic medication for pain in the musculoskeletal system within three days prior to a vaccination with AFFITOPE® PD01A or AFFITOPE® PD03A or Placebo - If a patient shows an acute febrile infection (≥ 37.8° Celsius) on the day of vaccination, administration of Investigational Medicinal Product (IMP) should be postponed until resolution of the infection - Infection with the human immunodeficiency virus (HIV, a negative test result within 30 days before screening is acceptable), Hepatitis B (HBsAg) or Hepatitis C - Significant systemic illness (e.g. chronic renal failure, chronic liver disease, poorly controlled diabetes, poorly controlled congestive heart failure and/or other deficiencies), if considered relevant by the investigator - Venous status rendering it impossible to place an i.v. access - Contraindications for MRI and lumbar puncture - Not able to understand and comply with protocol requirements, instructions, protocol-stated restrictions - Unwilling to provide informed consent.
