Main objective
Scope: Safety, Pharmacoeconomic, Efficacy
To demonstrate the non-inferiority of DMTs withdrawal compared to treatment continuation at 2 years, on disability progression, in “inactive” SPMS patients older than 50 years.
The definition of “inactive” SPMS patients refers to the Lublin classification : SPMS patients without recent evidence of focal inflammatory activity for at least 3 years (no clinical relapse and no radiological activity)
Secondary objectives 6
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for Disability progression using a composite score
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for Relapses
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for MRI parameters
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for Disease-free survival
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for Patients quality of life
- To compare the 2 groups at 2 years (treatment withdrawal vs treatment continuation) for Medico-economic impact: cost-utility study (differential cost per QALY gained)

|---|---|---|---|---|---|
| 1 | M0-M24 Controlled, randomized, rater-masked study with 2 parallel groups, comparing a treatment withdrawal group (1) to a treatment continued group (2) for 2 years (non-inferiority analysis).
In the group 1 (treatment withdrawal group), some patients will possibly resume their treatment. These patients will be followed for 2 years according to the trial schedule. In the statistical analyses, they will be included in the group 1. Indeed, the main objective of the present study is to evaluate the risk of disability progression after an attempt of DMT withdrawal.
In group 2 (treatment continued group), the previously established DMT will be continued at the same dose.
|
Randomised Controlled | None | Active Comparator: DMT continuation: The previously established therapy will be continued at the same dose during two years Experimental: DMT withdrawal: DMT will be immediately stopped after randomization.These patients will be followed for 2 years. |

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 5
- Patients ≥ 50 years old
- Secondary progressive phenotype for at least 3 years ; The secondary progressive phenotype will be defined as progressive deterioration of disability not due to relapse, with an increase of at least 1 EDSS point since the beginning of the progressive phase (or 0.5 EDSS point if EDSS score > 5.5)
- Disease modifying therapy of MS for at least 3 years (interferon, glatiramer acetate, teriflunomide, dimethyl fumarate, cyclophosphamide, azathioprine, methotrexate, mycophenolate mofetil, rituximab, ocrelizumab); Both patients with the same DMT or with successive DMTs during 3 years can be included. It is important to note that patients could have been treated with fingolimod or natalizumab 2 or 3 years before inclusion, but not during the year before inclusion
- No evidence of focal inflammatory activity for at least 3 years (no clinical relapse and no gadolinium enhancement on an MRI scan)
- EDSS ≥ 3
Exclusion criteria 9
- Patients treated with mitoxantrone or alemtuzumab, during the previous 3 years before inclusion
- Patients treated with natalizumab or fingolimod during the year before inclusion
- Change of disease modifying therapy of MS for less than a year
- Other neurological or systemic disease
- Incapacity to understand or sign the consent form
- Contraindication to MRI
- Pregnancy or breast-feeding
- Patient in another clinical trial
- Persons referred to in Articles L. 1121-5 to L. 1121-8 and L. 1122-1-2 of the Public Health Code (eg minors, protected adults, …)
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Percentage of patients experiencing disability progression (confirmed at 6 months) at 2 years. Disability progression will be defined as an increase in the EDSS of at least 1 point if the baseline EDSS was 5.5 or less, or 0.5 point if the Baseline EDSS was more than 5.5.
Secondary endpoints 6
- Disability - Time from DMT withdrawal to disability progression confirmed at 6 months; - Change in a composite disability progression score (increase in the EDSS score, or an increase in the time to perform the timed 25-foot walk ≥ 20%, or an increase in the time to complete the 9-hole peg test ≥ 20%) confirmed at 6 months; - Change in the SDMT score from baseline to 2-year;
- Relapses - Percentage of patients with at least one relapse from baseline to 2-year; - Annualized relapse rate during 2-year; - Time from DMT withdrawal to first relapse;
- MRI - Percentage of patients with one or more new or enlarging brain MRI lesions from baseline to 2-year; - Percentage of patients with at least one gadolinium enhancing lesion(s) at 6 months, and/or 1 year,and/or 2-year; - Change in brain volume from baseline to 2-year;
- Disease free survival - Percentage of patients with no evidence of disease activity (NEDA 3: no clinical relapse, no MRI activity, no disability progression) at 2-year; - Percentage of patients who resume DMT in the treatment withdrawal group at 2-year
- Quality of life - Change in the SEP-59 score from baseline to 2-year; - Change in the EuroQOL EQ-5D from baseline to 2-year;
- Medico economic impact - Incremental Cost Effectiveness Ratio (ICER) defined as the cost for QALY gained in “treatment withdrawal group” versus “treatment continued group”.
