Brief Summary
The purpose of the study is to research the association between receiving Tysabri® (natalizumab), interferon beta-1a, glatiramer acetate or not having any treatment for your MS and how it may or may not impact certain white blood cells and other immunological markers. This information may be useful in identifying risk factors in developing progressive multifocal leukoencephalopathy (PML). It does appear that the risk increases with the total number of natalizumab infusions. Patients who have not yet started a disease modifying therapy or who have been on one other than natalizumab are needed as controls to see how these biomarkers change. Patients at various stages of natalizumab treatment as well as natalizumab naïve are needed to allow for analysis of the change in potential markers over time.

Outcome Measures
Primary Outcomes (1)
Quantitative Assessment of CD62L in MS Patients on Immunomodulatory Agents
12 Months
Study Arms (5)
Group A TX Naive
Patient decided to start disease modifying treatment, either interferon beta-1a, glatiramer acetate or natalizumab. If interested and consented they would be assigned to Group A. Patient would have blood specimens taken up to 5 times over the next 19 months: Day 0; Day 28; Day 84: Day 336 and Day 508.
Group B TY 4-12 doses
Patient is currently prescribed and is taking natalizumab, has 4 to 12 doses. If interested patient could be consented and assigned to Group B. Patients will have their blood drawn Day 0; and around the time of the patient's 18th dose.
Group C 18 plus TY
Patient currently or close to being at 18 doses or 18 plus doses of natalizumab. If interested patient consented and assigned to Group C. Patient will have their blood drawn once: Day 0.
Group D Other DMT 18 plus
Patient is close to or currently at 18 doses or more of interferon beta-1a or glatiramer acetate. If interested patient consented and assigned to Group D. Patient will have their blood drawn once: Day 0.
Group E - Non-MS
10 participants without Multiple Sclerosis or other immunological illness. If interested participants consented and assigned to Group E. Participants will have their blood drawn once: Day 0.
Eligibility Criteria
Patients with Relapsing Remitting Multiple Sclerosis (RRMS) who are treated at Rocky Mountain Multiple Sclerosis Clinic, and who are currently undergoing disease modifying therapy, natalizumab, glatiramer acetate injections, interferon beta 1a, or who are beginning one of these disease modifying therapies.
You may qualify if:
- Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (PHI) in accordance with national and local subject privacy regulations.
- Aged 18 to 80 years old, inclusive, at the time of informed consent.
- Patients with a relapsing form of Multiple Sclerosis as determined by the treating or back-up neurologist per chart review.
- If getting natalizumab or scheduled to commence natalizumab infusion the patient must be enrolled in the TOUCH Prescribing Program and who is not expected to discontinue Tysabri® therapy prior to completion of the requirements of this study or must be currently prescribed and using interferon beta 1a or glatiramer acetate injections for 18 months; or, naïve to natalizumab, interferon beta 1a or glatiramer acetate and beginning treatment after consent.
- Patients screened for Group A must be completely naïve to natalizumab, patients beginning interferon beta-1a or glatiramer acetate must also be naïve to natalizumab.
- Patients screened for natalizumab naïve must have at least 30 days clear of other disease modifying therapies.
- Patients must be free of known systemic bacterial or viral infections.
- No fever over 99.5 degrees Fahrenheit in the last two weeks or at Baseline or prior to any scheduled specimen collection.
- No herpes zoster outbreaks within the last 30 days.
- No methylprednisolone sodium succinate infusion (solumedrol) or corticosteroid use within the last 30 days.
- Must weigh between 44 and 190 kg, inclusive.
You may not qualify if:
- Patient is unwilling or unable, in the opinion of the investigator, to comply with study instructions.
- Patients experiencing a MS relapse or exacerbation which results in methylprednisolone sodium succinate infusion 30 days prior to Baseline
- Patients with active, unknown infection etiology - if a patient is being treated for a known infection this would be allowed at the discretion of the Investigator, but if they present with signs of infection that has not been diagnosed they should be excluded.
- Fever of 99.6 or higher within the last two weeks prior to any of the scheduled specimen collection (Baseline, 1 month, 3 month, 12 month or 18 month).
- No prior immunosuppressant use (e.g., mitoxantrone, azathioprine, methotrexate, cyclophosphamide, mycophenolate mofetil).
- Specimen collection must occur Monday through Thursday.
