1. Male or female out-patients (except where an in-patient stay is required according to standard local practice for lumbar puncture) aged 18 to 65 years of age inclusive at the time of informed consent
2. Willing and able to provide written informed consent and to comply with the requirements of the protocol assessments/procedures
3. Relapsing MS
4. Clinical evidence of recent MS activity defined as either
- at least one documented relapse in the previous 12 months prior to Visit 2, or
- at least two documented relapses in the previous 24 months prior to Visit 2.
5. Radiological activity on Gd-enhanced MRI defined as both
- at least one CEL on MRI at Visit 2, and
- an increase of at least one CEL from Visit 2 to Visit 4, i.e., over the 8-week Baseline Control Period.
6. EDSS score 0-5.5
7. HLA-DRB1*15 positive
8. Neurological stability in the 30 days prior to Visit 5 (Study Day 1)
9. Prior vaccination against tuberculosis (TB)
10. If female, unless post-menopausal (for at least 2 years) or surgically sterilized, must be willing to use two highly effective methods of contraception throughout the entire duration of
the trial and for 90 days following the last dose of ATX-MS-1467
11. If male, must be willing to use two highly effective methods of contraception throughout the entire duration of the trial and for 90 days following the last dose of ATX-MS-1467.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 19
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 1
1. Primary progressive MS
2. Inability to comply with MRI scanning, including contra-indications to MRI such as known allergy to gadolinium contrast dyes, claustrophobia, presence of a pacemaker, cochlear
implants, ferromagnetic devices or clips, intracranial vascular clips, insulin pumps, nerve stimulators
3. Previous treatment with ß-interferon, plasma exchange, intravenous gamma globulin within the 8 weeks prior to Study Day 1 (Visit 5); subjects receiving such treatment at Visit 2 (i.e.,
at the start of the Baseline Control Period) must discontinue treatment and commence washout as soon as it has been confirmed that they are eligible for the trial based on their
Visit 2 MRI scan
4. Previous treatment with steroids (administered via the oral and/or parenteral routes) or adrenocorticotropic hormone within the 30 days prior to the Visit 2 MRI scan; subjects
receiving such treatment at screening (Visit 1) must have completed treatment 30 days prior to the Visit 2 MRI scan
5. Previous treatment with glatiramer acetate
6. Previous treatment with: cytotoxic agents (including but not limited to cladribine, mitoxantrone, cyclophosphamide, azathioprine, methotrexate), fingolimod, laquinimod,
teriflunomide, total lymphoid irradiation, stem cell or bone marrow transplantation, or monoclonal antibody therapy (including natalizumab, daclizumab, alemtuzumab, ocrelizumab)
7. Prior exposure to dimethyl fumurate (BG-12) or dirucotide
8. Prior exposure to any disease-related T cell vaccine or peptide-tolerizing agent for the treatment of MS, including ATX-MS-1467
9. Use of any investigational drug or experimental procedure for MS (including cytokine or anticytokine therapy) within the 30 days prior to screening (Visit 1)
10. Inadequate liver function, defined by aspartate aminotransferase or alanine aminotransferase (ALT) > 3 times the upper limit of normal at screening or at any of the pre-treatment visits (Visits 2-4)
11. Lymphocyte count < 500/µL or neutrophil count < 1500/µL at screening or at any of the pre-treatment visits (Visits 2-4)
12. Major medical illness such as cardiac, endocrinological, hepatic, immunological (other than MS), metabolic, genito-urinary, pulmonary, gastrointestinal, dermatological, or other major
disease that would preclude participation in the trial
13. Known history of active or chronic infectious disease or any disease which compromises immune function (e.g., positive for human immunodeficiency virus, human T-lymphotrophic
virus-1, untreated Lyme disease, untreated TB or hepatic viral disease [hepatitis B and C])
14. Any renal condition that would preclude the administration of gadolinium, e.g., acute or chronic severe renal insufficiency (glomerular filtration rate [GFR] < 30 mL/min/1.73 m2)
15. History of malignancy, including both solid tumor and hematological malignancies, but excluding basal cell and in situ squamous cell carcinomas of the skin that have been excised
and resolved, in situ cervical cancer or prostatic cancer with normal prostatic specific antigen
16. Clinical evidence of severe uncontrolled depression, active suicidal ideation or suicide attempt
17. Any other significant medical or psychiatric conditions that, in the opinion of the Investigator, would preclude participation in the trial or impair the ability to give informed consent
18. Major surgery in the 4 weeks prior to screening (Visit 1)
19. Known hypersensitivity to the trial medication or diluents
