NCT00942214

Brief Summary

Information from blood samples may help us for choosing the best treatment in future personalized medicine. Natalizumab (NTZ) a current treatment for MS can be used as a second line therapy if a suboptimal response to disease modifying drugs. When to introduce NTZ is not consensual. The investigators hypothesized that biological information could rationalize choice and thus designed a prospective open label trial to test biological markers before treatment.

Outcome Measures

Primary Outcomes (1)

Also known as: Tysabry (brand name)

Eligibility Criteria

Age18 Years - 55 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patients between the ages of 18 and 55 years.
  • Diagnosis of relapsing multiple sclerosis according to McDonald criteria.
  • EDSS score of 0 to 5.0 on the EDSS scale. One of the following 2 items:
  • Patients who have failed to respond to a full and adequate course of a beta-interferon. Patients have had at least 1 relapse in the previous year while on therapy, and have at least 9 T2-hyperintense lesions in cranial MRI or at least 1 Gadolinium-enhancing lesion.
  • Patients with rapidly evolving severe relapsing remitting multiple sclerosis, defined by 2 or more disabling relapses in one year, and with 1 or more Gadolinium enhancing lesions on brain MRI or a significant increase in T2 lesion load as compared to a previous recent MRI.

You may not qualify if:

  • Hypersensitivity to natalizumab or to any of the excipients.
  • Progressive Multifocal Leukoencephalopathy (PML).
  • Increased risk of opportunistic infections, including immunocompromised patients (including those currently receiving immunosuppressive therapies or those immunocompromised by prior therapies, e.g. mitoxantrone or cyclophosphamide within 1 year before Tysabri.
  • Combination with beta-interferons or glatiramer acetate.
  • Known active malignancies, except for patients with cutaneous basal cell carcinoma.
  • Children and adolescents.
