Inclusion Criteria

Inclusion Criteria
Related to disease
1. Patients with either primary progressive or secondary progressive
multiple sclerosis with onset of symptoms at least five years before
baseline and with no relapse diagnosed according to the 2017 revised
McDonald’s criteria at least two years before screening
2. Patients with Expanded Disability Status Scale (EDSS) score between 3.0 to 6.0 (both inclusive) at screening and baseline
3. Patients with an EDSS score progression =1 point with no improvement during 2 years before screening
4. Absence of T1 Gadolinium-enhancing brain lesions as measured by MRI at screening

Other inclusion criteria
5. Male or female patients aged between 18 and 65 years at screening
6. Weight >45 kg and BMI between 18 and 35 kg/m2 at screening and baseline
7. Contraception, to be assessed at screening and at baseline:
Female patients of childbearing potential (entering the study after a menstrual period and who has a negative pregnancy test), who agrees to use a highly effective method of contraception and an effective method of contraception by her male partner during the study and for 3 months and a
half after the last treatment intake

Male patients with a female partner of childbearing potential who agrees to use a highly effective method of contraception and an effective method of contraception by his female partner during the study and for 3 months and a half after the last treatment intake OR who agrees to use an effective method of contraception and a highly effective method of contraception by his female partner during the study and for 3 months and a half after the last treatment intake

Highly effective and effective methods of contraception are detailed in the
Appendix 14.1 of the protocol.

8. Patients able to understand, and willing to sign, and date the written informed consent form prior to any protocol-specific procedures, at screening. If patients are duly capable of study consent but are unable to sign by themselves due to aggravation of disease condition, written informed consent can be obtained from a legally authorized representative who can sign on behalf of the patients after confirming the patients' agreement to study participation
9. Patients able and willing to comply with study protocol and to come onsite
as per protocol visits schedule, assessed at screening and at baseline.

Exclusion Criteria

Exclusion Criteria:
Related to disease

2. Inability to complete screening MRI (contraindications for MRI) and/or
any known allergy or hypersensitivity or any contra-indication to
gadolinium macrocyclic
3. Patients treated with other disease modifying treatments in the time
frames and conditions mentioned under previous treatment wash out
period, assessed at baseline
4. Patients with lymphocytes <1.0 × 109/L at screening and at baseline

Other exclusion criteria

- Hypertension (uncontrolled) ; - Diabetes; - Kidney disease; - Current tabagism (= 10 Pack-year: equivalent to 1 pack of 20 cigarettes for 10 years with the formula N (number of packs of 20 cigarettes smoked daily) × T (number years smoking)) Patients who stopped smoking 6 months prior to the evaluation, are not concerned.

Primary Outcome Measures
NameTimeMethod
Main Objective: To evaluate the efficacy and safety of oral masitinib versus placebo in the<br>treatment of patients with primary progressive or secondary progressive multiple<br>sclerosis without relapse. ;Secondary Objective: The secondary objectives of the study are to evaluate the efficacy of masitinib compared with placebo on a range of clinical parameters of multiple sclerosis. The secondary objectives also include the assessment of safety and tolerability of masitinib as compared to placebo in terms of adverse events, vital signs, physical examination, ECG, and clinical laboratory tests. <br>;Primary end point(s): The primary endpoint is to assess the efficacy of masitinib 3.0 mg/kg/day with a dose escalation to 4.5<br>mg/kg/day after four weeks on the time to confirmed (12-weeks CDP) EDSS progression. Progression<br>is defined as 1-point worsening when EDSS score =5.5, or 0.5-point worsening if baseline score >5.5. ;Timepoint(s) of evaluation of this end point: Week 96
