About this study
Official title: Analysis of Lymphocyte Cell Surface Adhesion Marker Expression in a Natalizumab Treated Population With Active Control Assessment
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.
Read the detailed description
Patients at various timepoints in their MS treatment or who are beginning certain MS treatments will be consented and have blood specimens collected to allow for an immunological comparison. The decision to treat with disease modifying therapies is made independently from this observational study.
Primary endpoint: To further understand the delineation of lymphocyte cell adhesion marker down regulation within a treatment naïve patient population and at various stages of treatment.
Secondary endpoint: To understand the correlation between natalizumab pharmacodynamics, pharmacokinetics and lymphocyte cell adhesion marker down regulation.
The results of various biomarkers and immunological testing (including CD62L, LFA-1, sCD62L, sLFA-1, sVCAM, VLA-4 saturation, IgG4, CBC with absolute differential) will be compared amongst the groups consented. The treatment naive group will be compared longitudinally.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 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. |

Questions about this trial
What is this clinical trial studying?
An observational study of Multiple Sclerosis, run by John F. Foley, MD at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quantitative Assessment of CD62L in MS Patients on Immunomodulatory Agents (time frame: 12 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01626248, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2013.
