研究概览

简要总结

A trial in patients with relapsing remitting multiple sclerosis (RRMS)

Main objectives:

  • To evaluate changes in the reconstitution of immune surveillance over time upon switching from natalizumab to fingolimod assessed by a change in the expression of CD49d.
  • To evaluate changes in the migratory capacity of immune cells/peripheral blood mononuclear cells (PBMCs) upon switching from natalizumab to fingolimod in an in-vitro model of the blood-brain-barrier (BBB).
  • To evaluate changes in paraclinical disease activity over time upon switching from natalizumab to fingolimod assessed by MRI (changes in Gd+, T2w lesions and DTI).
  • To evaluate changes in T1w / FLAIR lesions upon switching from natalizumab to fingolimod.

详细描述

Patients are screened and must sign informed consent at visit 1. At the 2nd visit, all patients receive a baseline infusion of Natalizumab, which is followed by an 8 week washout Phase. After the washout Phase all patients receive fingolimod for 32 weeks.

入选标准

  • Written informed consent must be obtained before any assessment is performed.
  • Male and female subjects aged 18-65 yrs.
  • Subjects with RRMS, defined by 2010 rev. McDonald criteria.
  • Patients with an (EDSS) score of 0-6.0 inclusive.
  • Patients on treatment with natalizumab for ≥ 12 months prior to screening where treatment discontinuation is considered for any of the following reasons:
  • treatment duration for more than 2 years
  • positive JC virus (JCV) antibody status
  • adverse effects including hypersensitivity reactions
  • presence of anti-natalizumab neutralizing antibodies
  • any other valid medical reason

排除标准

  • Patients with a history of chronic disease of the immune system other than MS, which requires systemic immunosuppressive treatment, or a known immunodeficiency syndrome.
  • Patients with Crohn´s disease or ulcerative colitis.
  • Patients who have been treated with:
  • systemic corticosteroids or immunoglobulins within 1 month prior to baseline.
  • immunosuppressive medications such as azathioprine, cyclophosphamide or methotrexate within 3 months prior to baseline.
  • monoclonal antibodies (excluding natalizumab) within 3 months prior to baseline.
  • cladribine or mitoxantrone at any time.
  • History of malignancy of any organ system (other than cutaneous basal cell carcinoma).
  • Uncontrolled diabetes mellitus (HbA1c >7%).
  • Diagnosis of macular edema during Screening Phase.
  • Severe active infections, active chronic infection.
  • Negative for varicella-zoster virus immunoglobulin G antibodies prior to baseline.
  • Patients that received any live or live-attenuated vaccine (including varicella-zoster virus or measles) within 1 month prior to baseline.
  • Patients who have received total lymphoid irradiation or bone marrow transplantation.
  • Patients with any medically unstable condition, as assessed by the investigator.
  • Patients with certain cardiovascular conditions and/or findings in the screening ECG.
  • Patients with certain lung diseases.
  • Patients with certain hepatic conditions.
  • Patients with a screening white blood cell (WBC) count <3,500/mm3 or lymphocyte count <800/mm
  • Patients with certain neurologic/psychiatric disorders:
  • Patients unable to undergo MRI scans, including claustrophobia or history of hypersensitivity to gadolinium-diethylenetriaminepentacetate (Gd-DTPA).
  • Patients who have received an investigational drug or therapy within 180 days or 5 half-lives before baseline, whichever is longer.
  • Pregnant or nursing (lactating) women, confirmed by a positive human chorionic gonadotropin laboratory.
  • Women of child-bearing potential unless they are using effective contraception during the study and for 5 half-lives after stopping treatment. In case of use of oral contraception women should have been stable on the same medication for a minimum of 3 months before baseline.
  • History of hypersensitivity to the study drugs or to drugs of similar chemical classes.
  • Prior participation in a trial with fingolimod.
