Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the phase II study is to determine whether intradermal (in Belgium) or intranodal (in Spain) injection of tolDC is effective and safe. Adverse events, clinical relapse rates, neurological disability (assessed using various scales) and magnetic resonance imaging (MRI) endpoints will be measured over 18 months. Patients, receiving the tolDC intervention, will be compared to a standard-of-care control group - primairy endpoints: safety (reporting of adverse events) and efficacy (the number of new and/or enlarging T2 lesions on MRI scans) - secondary endpoints: (i) clinical: relapse rate, EDSS, 9HPT, T25FW and SDMT, and (ii) non-clinical: all other MRI outcomes - Tertiary and exploratory endpoints: immunological responses and patient-reported quality of life (MS-QoL54);Secondary Objective: not applicable;Primary end point(s): - Efficacy (the number of new and/or enlarging T2 lesions on MRI scans) - Safety (reporting of adverse events) ;Timepoint(s) of evaluation of this end point: - trial entry, defined as the day that the patient signs the informed consent form - at each vaccination visit (V1 to V6) - at follow up visits (F1, F3, F6 and F12) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - clinical: relapse rate, EDSS, 9HPT, T25FW and SDMT - non-clinical: T2 lesion volume, atrophy rate, total brain volume and fractional anisotropy (FA) on MRI scans;Timepoint(s) of evaluation of this end point: CLINICAL: - trial entry, defined as the day that the patient signs the informed consent form - at each vaccination visit (V1 to V6) - at follow up visits (F1, F3, F6 and F12) NON-CLINICAL: - at screening, V1, V4, V6, F1, F6 and F12 | — |
