E.3 | Principal inclusion criteria |
• Age 18 to 60 years • PPMS according to the McDonald (2010) and Lublin (2014) criteria • Disease duration at least one year • Expanded Disability Status Scale (EDSS) under or equal to 6.5 • Written informed consent to study participation • No other signs of significant disease judged by the investigator • Eligible for randomization to active treatment or placebo as assessed by cerebrospinal fluid (CSF) Neurofilament light chain (NFL) levels above 380ng/L • Not eligible for randomization as assessed by CSF biomarker studies but accepts follow-up and open-label treatment per protocol • Patients not eligible for randomization due to low NFL concentrations in CSF at screening can be followed up after 48 weeks, and are eligible for open-label treatment if they fulfil one of the following clinical criteria of disease progression: • 1 point increase in EDSS score from screening to week 48 if screening EDSS less than 6 • 0.5 point increase in EDSS score from screening to week 48 if screening EDSS is more than 5.5 • 2 point increase in a physical functional system • Worsening in Symbol Digit Modalities Test, 9 hole peg test or timed 25 foot walk test more than 20% from screening to week 48

E.5 End points |
E.5.1 | Primary end point(s) |
The primary aim of the study is to assess whether 48 weeks of treatment with dimethyl fumarate can decrease neuroaxonal damage in PPMS as assessed by: • Difference in change in the CSF concentration of NFL from screening to week 48 in PPMS patients treated with dimethyl fumarate or placebo
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Evaluation of the primary endpoint is done after 48 weeks of treatment with either dimethyl fumarate or placebo |
|
E.5.2 | Secondary end point(s) |
• Clinical endpoints: comparison of change from screening to week 48 in patients treated with dimethyl fumarate and placebo for the following variables: Expanded Disability Status Scale (EDSS) Timed 25-Foot Walk (T25FW) Nine-Hole Peg Test (9HPT) Brief International Cognitive Assessment for MS (BICAMS) Symbol Digit Modalities Test (SDMT)
• CSF endpoints: comparison of change from screening to week 48 in patients treated with dimethyl fumarate and placebo for the following variables: IgG-index CSF-serum albumin quotient Concentrations of: chitinase-3-like-1, sCD14, sCD27, BCMA (TNFRSF17) and myelin basic protein (MBP) • Magnetic resonance imaging (MRI) endpoints: comparison of change from screening to week 48 in patients treated with dimethyl fumarate and placebo for the following variables: Number of new or enlarged T2 lesions Fractional anisotropy (FA) in Normal Appearing White Matter (NAWM) Lesion volume Magnetization Transfer Ratio (MTR) in lesions Thalamic volume Percentage brain volume change (PBVC)

|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
