Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
We hypothesize that GA plus corticosteroids versus GA alone will prevent or reduce the re-occurrence of MS disease activity after discontinuation of natalizumab over a 12 month period. We further hypothesize that natalizumab therapy followed by GA treatment allows the reconstitution of the peripheral and CNS immune homeostasis.
Primary objective:
The primary endpoint will be the annualized relapse rate over the post randomization months as well as estimates of change over the natalizumab therapy period over the entire 12 months.
Secondary objectives:
To determine if and how long it takes for restoration of immune homeostasis under GA therapy following discontinuation of natalizumab.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A total of 200 patients with relapsing forms of multiple sclerosis (MS) will be recruited at 20 study sites in the United States and Europe.
Natalizumab at a dose of 300 mg intravenous (i.v.) infusion each month will be given as standard of care for at least 9 months prior to patient being enrolled in the study. One day after the last infusion of natalizumab the patient will start conversion paradigms to Glatiramer Acetate (GA). GA will be administered daily at a subcutaneous (s.c.) dose of 20 mg. On day 1, 2 months after the patient has been on GA therapy, patient will be randomized to be treated with methylprednisolone or methylprednisolone placebo at an oral dose of 192 mg/day po for 5 consecutive days per month for the duration of the study.
Both Natalizumab and Glatiramer Acetate (GA) have been approved by the FDA to treat relapsing remitting multiple sclerosis.
Natalizumab will not be given as a study medication. Part of the inclusion criteria is that patients are already receiving Natalizumab as standard of care.
Natalizumab until randomization will be provided by the patients' medical insurance. Glatiramer acetate (GA) from randomization till the end of the study (for 12 months) will be provided by the patients' medical insurance. Teva Pharmaceuticals is the manufacturer of methylprednisolone and methylprednisolone placebo 24-mg tablets, which will look identical.
Treatment Arms
During a 1 month screening period (month -1), inclusion and exclusion criteria will be verified, and subjects will be enrolled in the GA only portion following registration with the web-based data entry system and at month 3, they will be randomly assigned to treatment that will be stratified according to study site in varying block sizes One day after the last natalizumab infusion (month 0), 200 Patients on natalizumab therapy will be started on GA. On day 1 of month 3, subjects will be randomized 1:1 to receive either:
1. Methylprednisolone placebo ("GA \& PL") or
2. Methylprednisolone ("GA \& MP") in addition to GA therapy. Randomization to the two treatment arms will occur via a random number generator by a centralized data entry system that checks eligibility prior to initiating randomization to prevent inappropriate inclusions.
Study Endpoints:
1. The primary endpoint will be the annualized relapse rate.
2. A key secondary endpoint is the percentage of relapse-free patients at 12 months.
3. Other secondary outcomes are the rate of early relapse rebound (assessed in all 200 patients prior to randomization), number of new GD+ lesions on MRI over the 12 months treatment period, defined as the period following the first infusion (month 0) to 6 months and 12 months after randomization, annualized relapse rate, and progression of neurological as assessed by changes in EDSS.
4. Other MRI outcomes will include the cumulative combined unique activity (CUA) (new or enlarging T2 lesions or enhancing lesions).
5. Another secondary endpoint is the percentage of patients who appear to be free of disease activity as measured by clinical relapses, disability progression measured by the Expanded Disability Status Scale EDSS), and the cumulative combined unique activity (CUA) (new or enlarging T2 lesions or enhancing lesions) on MRI at 12 months.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Diagnosis of relapsing forms of MS using revised McDonald Criteria 11.
3. Patients who have not failed GA therapy.
4. EDSS 0 - 5.5 (Functional system changes in cerebral (or mental) functions and in bowel and bladder functions not used in determining EDSS for protocol eligibility).
5. No more than two relapses in the 12 months prior to initiating natalizumab therapy.
6. A minimum of 9 doses of natalizumab prior to randomization.
7. Disease controlled under natalizumab treatment demonstrated by the absence of relapses (no relapse in the 9 months prior to randomization)
8. Understood and signed written informed consent, obtained prior to the study subject undergoing any study-related procedure, including screening tests.
Enrollment of patients in the TOUCHTM program at United States of America study sites as long as required: According to guidelines established by the Department of Health \& Human Services, natalizumab is currently only available under a special restricted distribution program called TOUCHTM within the United States
Exclusion Criteria
2. Initiation of new immunosuppressant treatment after the subject becomes protocol-eligible (except for corticosteroids) or enrollment in a concurrent trial unless an exception is granted following consideration by the MS Review Panel.
3. Patients who were treated with GA before natalizumab therapy and failed GA therapy.
4. Subjects with any history of cytopenia consistent with the diagnosis of myelodysplastic syndrome (MDS).
5. Active hepatitis B or hepatitis C infection or evidence of cirrhosis.
6. HIV positivity.
7. Uncontrolled diabetes mellitus defined as HbA1c \> 8% and/or requiring intensive management.
8. Uncontrolled viral, fungal, or bacterial infection (excluding asymptomatic bacteriuria).
9. Any condition that, in the opinion of the investigators, would jeopardize the ability of the subject to tolerate treatment with GA.
10. Prior history of malignancy, except localized basal cell or squamous skin cancer. Other malignancies for which the subject is judged to be cured by the administered therapy, such as head and neck cancer, or breast cancer, will be considered on an individual basis by the Study's MS review panel.
11. Positive pregnancy test or inability or unwillingness to use effective means of birth control. Effective birth control is defined as:
1. Refraining from all acts of vaginal intercourse (abstinence),
2. Consistent use of birth control pills,
3. Injectable birth control methods (®Depo-Provera, ®Norplant),
4. Tubal sterilization or male partner who has undergone vasectomy,
5. Placement of an IUD (intrauterine device)
6. Use, with every act of intercourse, of a diaphragm with contraceptive jelly and/or condoms with contraceptive foam.
12. Presence of metallic objects implanted in the body that would preclude the ability of the subject to safely have MRI exams.
13. Psychiatric illness, mental deficiency, or cognitive dysfunction making compliance with treatment or informed consent impossible.
