An acute exacerbation, relapse, in persons with RRMS, either newly diagnosis or on treatment with one of the long-term immunomodulatory drugs, or possible MS where the diagnosis is supported by typical MRI or cerebrospinal fluid changes typical of MS (this enables inclusion of persons with a first neuroinflammatory bout, with high risk of developing MS before fulfilling the McDonald criteria for definite MS, or high risk for developing MS in the category clinically isolated syndrome (CIS)/possible MS with supporting MRI lesions and/or cerebrospinal fluid aberrations suggesting intra-thecal immunoglobulin synthesis with oligoclonal bands/and/or increased free Kappa Light chains. The relapse should be deemed to require relapse treatment by the investigator and affect a functional domain with a minimum of grade 2 |

Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, if they are using effective methods of contraception during the study. Acceptable birth control methods are those with a failure rate of less than 1% per year when used consistently and correctly according to CTFG, September 2014 "Recommendations related to contraception and pregnancy testing in clinical trials". Such methods include |

|
Combined (estrogen and progestogen containing hormonal contraception associated with inhibition of ovulation |
|
|
|
|
oral |
|
|
|
|

transdermal 2. progestogen-only hormonal contraception associated with inhibition of ovulation |
|
|
|
|
oral |
|
|
|
|
injectable |

|
|
|
implantable 3. intrauterine device (IUD) 4. intrauterine hormone-releasing system (IUS) 5. bilateral tubal occlusion 6. total abstinence or vasectomized partner |

A pseudo-relapse should be excluded, as deemed by the experienced treating neurologist, and as evidenced by an active infection, likely with fever, with reappearing new signs and symptoms in a previously affected neurological function

|
|
|
Female patients with childbearing potential, if pregnancy cannot be excluded by pregnancy test (urine point-of-care pregnancy test)
|

Patient is participating in other interventional study
|
|
|
|
|
General infection or any other condition judged by the treating neurologist to contra-indicate Imatinib
|
|
|
|
|
Any laboratory deviation of general bodily functions such as kidney, or renal function judged to be of clinical significance by the treating neurologist constitutes an exclusion criteria
