You may not qualify if…

Patients will be entered into this trial only if they meet none of the following criteria:
For relapsing and progressive MS forms: the disability status according to the EDSS scale is larger than 7.0 or the age is larger than 55 years.
Only applicable for progressive MS (PPMS/SPMS), where the disease duration is longer than 15 years.
History of a malignancy unless disease free for ≥5 years with the exception of basal or squamous cell skin cancer
Known history of and/or active infection with hepatitis B (hepatitis B surface antigen positive)
Known history of infection with hepatitis C virus unless treated and confirmed to be polymerase chain reaction (PCR) negative
Any active uncontrolled bacterial, viral or fungal infection
A history of and/or active infection with human immunodeficiency virus (HIV)
A history of active or latent tuberculosis (TB); TB testing should be performed at screening (Quantiferon test). Confirmed active or latent TB the patient can be re-screened after full completion of anti-tuberculosis treatment (9 months of Isoniazide therapy)
History of neuromyelitis optica spectrum disorder (NMOSD) or MOG antibody associated disease.
History of CNS or spinal cord tumor, metabolic or infectious causes of myelopathy, genetically inherited progressive CNS disorder, sarcoidosis or non MS-progressive neurological condition affecting the ability to perform the study assessments
History of cytopenia consistent with MDS diagnosis
History of sickle cell anemia or other hemoglinopathies
Primary immune deficiency disease
Patients with positive antiphospholipid antibodies, anti-cardiolipin or lupus anticoagulant.
History of moderate or worse renal impairment (eGFR < 30 ml/min/1.73 m2)
Prevalent inflammatory diseases of the GI tract (e.g. Inflammatory bowel disease, Peptic ulcer) which could result in a higher risk for gastrointestinal perforation.
The following cardiac conditions:
New York Heart Association Stage III or IV congestive heart failure Myocardial infarction or coronary artery bypass graft ≤ 6 months prior to enrollment History of clinically significant ventricular arrhythmia or unexplained syncope, not believed to be vasovagal in nature or due to dehydration
History of severe non-ischemic cardiomyopathy Medications:
Systemic corticosteroids >10 mg within 7 days prior to leukapheresis; T cell targeting drugs (e.g. mycophenolate mofetil, calcineurin inhibitors) within 21 days prior to leukapheresis, Previous CAR T cell therapy, Live vaccines within 30 days prior to leukapheresis, Current Cytotoxic drugs Other MS disease modifying drugs (as stated in 5.8.1.)
Hypersensitivity against any drug or its ingredients/impurities that is scheduled or likely to be given during trial participation, e.g. as part of the mandatory preparative lymphodepletion or rescue medication/salvage therapies for treatment related toxicities;
Contraindication of trial related procedures as judged by the investigator
Pregnant of breast-feeding females; female patients of child-bearing potential not willing to practice a highly effective form of birth control from leukapheresis and for 12 months after dosing the IMP
Concurrent participation in another interventional trial
