Brief Summary:
A first-in-human clinical trial to treat patients with multiple sclerosis by vaccination with tolerogenic dendritic cells (tolDC), generated using Good Manufacturing Practice (GMP) will be conducted. In doing so, the feasibility and safety of administering myelin-derived peptide-pulsed tolDC in patients with MS will be assessed.

Condition or disease Intervention/treatment Phase
Multiple Sclerosis Biological: tolerogenic dendritic cells (tolDC) Phase 1

Detailed Description:
A phase I dose-escalating clinical trial will be conducted in a coordinated and comprehensive manner to determine safety and tolerability, and to enable selection of a suitable dose regimen for phase II trials. The primary objective of the phase I study will be to determine whether tolDC-based therapy is safe and well tolerated and to establish the dose-response, with clinical relapse rates, neurological disability (assessed using various scales) and MRI endpoints, measured over 12 months. Patients will serve as their own controls pre- and post-vaccination. Completion of screening assessments and confirmation of eligibility criteria should take no longer than 6 weeks. First-line treatments will be stopped 6 weeks before baseline at the latest.

Arm Intervention/treatment
Experimental: tolerogenic dendritic cells (tolDC)
Each vaccine (5x106, 10x106 , or 15x106cells in 500 µL NaCl 0.9% solution supplemented with 5% human albumin) will be administered through intradermal injection at 5 sites (100 µL/site) in the subclavicular region (5-10 cm from the cervical lymph nodes). Injection sites will alternate between left and right sides.
Biological: tolerogenic dendritic cells (tolDC)
dose-escalation




Primary Outcome Measures :
  1. Safety (Occurrence and severity of adverse events will be recorded) [ Time Frame: 6 months ]
    Occurrence and severity of adverse events will be recorded

  2. Feasibility (Generation of GMP-grade cell product released according to QC) [ Time Frame: 6 months ]
    Generation of GMP-grade cell product released according to QC


Secondary Outcome Measures :
  1. Expanded disability status scale (EDSS) [ Time Frame: 6 months ]
    The patients' disability level well be checked during every visit

  2. 9 Hole Peg Test (9HPT) [ Time Frame: 6 months ]
    This is a brief, standardized, quantitative test of upper extremity function

  3. 25 Foot walk test (T25FW) [ Time Frame: 6 months ]
    This is a quantitative mobility and leg function performance test based on a timed 25-walk.

  4. Symbol Digit Modalities test (SDMT) [ Time Frame: 6 months ]
    This test quickly screens for organic cerebral dysfunction

  5. Number of Gd-enhancing lesions on MRI [ Time Frame: 6 months ]
    By means of MRI Gd-enhancing lesions will be analysed

  6. Number of new or enlarging T2 lesions on MRI [ Time Frame: 6 months ]
    By means of MRI new or enlarging T2 lesions will be analysed


Other Outcome Measures:
  1. MSQOL-54 [ Time Frame: 6 months ]
    The MSQOL-54 is a multidimensional health-related quality of life measure that combines both generic and MS-specific items into a single instrument

  2. whole-blood lymphocyte phenotyping - immunomonitoring [ Time Frame: 6 months ]
    Blood samples will be analysed into detail, before and after completion of the vaccination cycle

  3. cytokine profiling - immunomonitoring [ Time Frame: 6 months ]
    Blood samples will be analysed into detail, before and after completion of the vaccination cycle

  4. pathogenic T cell responses - immunomonitoring [ Time Frame: 6 months ]
    myelin-specific T cell reactivity will be determined before and after completion of the vaccination cycle
