  Purpose

This is a Phase 3b, multicenter, international study conducted in 2 parts. Upon completion of the placebo-controlled period (Part 1), subjects will have the option of enrolling in a 2-year open-label extension (Part 2).

Part 1: The primary objective of the study is to investigate whether treatment with natalizumab slows the accumulation of disability not related to relapses in subjects with secondary progressive multiple sclerosis (SPMS).

The secondary objectives of Part 1 of this study are: To determine whether treatment with natalizumab improves the condition of subjects in this study population, including measurements such as walking speed and ability, magnetic resonance imaging (MRI), Expanded Disability Status Scale (EDSS) and subject-reported quality of life.

Part 2: The primary objective of Part 2 of the study is to evaluate the safety profile of natalizumab in subjects with SPMS.

The secondary objectives of Part 2 of the study are as follows: To investigate long-term disability (based on clinical or patient-reported assessments) in subjects with SPMS receiving natalizumab treatment for approximately 4 years; To assess change in brain volume and T2 lesion volume.

  • Considered by the Investigator to be immunocompromised based on medical history, physical examination, laboratory testing, or any other testing required by local guidelines, or due to prior immunosuppressive or immunomodulating treatment.
  • Subjects for whom magnetic resonance imaging (MRI) is contraindicated (i.e., have pacemakers or other contraindicated implanted metal devices, are allergic to gadolinium, or have claustrophobia that cannot be medically managed).
  • History of any clinically significant (as determined by the Investigator) cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic (other than MS), dermatologic, psychiatric, and renal, or other major disease that would preclude participation in a clinical study.
  • History of malignant disease, including solid tumors and hematologic malignancies (with the exception of basal cell and squamous cell carcinomas of the skin that have been completely excised and are considered cured).
  • Known history of or positive test result for Human Immunodeficiency Virus (HIV).
  • Positive test result for hepatitis C virus (test for hepatitis C virus antibody [HCV Ab]) or hepatitis B virus (test for hepatitis B surface antigen [HBsAg] and/or hepatitis B core antibody [HBcAb]).
  • History of transplantation or any anti-rejection therapy.
  • Presence of any infectious disease (e.g., cellulitis, abscess, pneumonia, septicemia) within 30 days prior to screening.
  • History of progressive multifocal leukoencephalopathy (PML) or other opportunistic infections.

Treatment History (Part 1)

  • Any prior treatment with cell-depleting therapies, including total lymphoid irradiation, cladribine, rituximab, alemtuzumab, or bone marrow ablation.
  • Any prior treatment with natalizumab.
  • Treatment with mitoxantrone, cyclophosphamide, cyclosporine, azathioprine, methotrexate, mycophenolate mofetil, T cell or T cell receptor vaccination, fingolimod, daclizumab, or cytapheresis within 6 months prior to randomization.
  • Treatment with intravenous or oral corticosteroids, intravenous immunoglobulin (IVIg), or plasmapheresis for treatment of multiple sclerosis within the 3 months prior to randomization.
  • Treatment with glatiramer acetate or any interferon beta preparations within 4 weeks prior to randomization.

Inclusion Criteria (Part 2):

•Subjects must have participated in and completed Part 1 per protocol, and have documented assessment attempts for Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), and 9-Hole Peg Test (9HPT) prior to first open-label dosing.

Exclusion Criteria (Part 2):

  • Subjects with any significant change in clinical status, including laboratory tests that, in the opinion of the Investigator, would make them unsuitable to participate in this extension study. The Investigator must re-review the subject's medical fitness for participation and consider any diseases that would preclude treatment.
  • Subjects who discontinued study treatment in Part 1 OR had fewer than 20 infusions in Part 1 OR missed 2 or more consecutive infusions in Part 1.
