History of Changes
  Purpose

The purpose of this study is to see if we can find a new way to test how certain Multiple Sclerosis (MS) medications work in the body and to better understand how the medicines change certain substances (cells) found in the immune (protective) system.

Blood test will be drawn by doing the following:

  • Use a new method called the "Immuknow®" Test to see if this method will help to better understand how MS medicines work.
  • Measure certain levels of immune cells in a new way, to see if it this will help to understand the body's response to MS medicines.

These methods will test those with MS who are not taking any MS medications, to help us compare the results.

About 100 subjects will be enrolled in this study at the Partners Multiple Sclerosis Center at Brigham and Women's Hospital. Biogen Idec, Inc. of Cambridge, MA, is paying for this study to be done.

Primary Outcome Measures:
  • The primary objective of this study is to determine the effects of various therapies (immunomodulatory as well as immunosuppressive) on ATP levels in CD4+ cells. [ Time Frame: 1 blood draw ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Secondary objective is to correlate the expression of ATP in CD4+ cells with CD4+ cell count. [ Time Frame: 1 blood draw ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples Without DNA

About 1 ½ teaspoons of blood will be drawn.


Enrollment: 100
Study Start Date: March 2008
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Detailed Description:

The primary objective of this study is to determine the effects of various therapies (immunomodulatory as well as immunosuppressive) on ATP levels in CD4+ cells and to determine whether the "ImmuKnow®" assay is an appropriate screening tool to assess the immunocompetence of potential Tysabri patients.

Secondary objective is to correlate the expression of ATP in CD4+ cells with CD4+ cell count.

Tertiary objective is to examine the level of regulatory T-cells (CD4+ and CD25+) in MS patients and its possible correlation to the therapy used, and how well a recently proposed marker of regulatory T-cells, LAP, correlates with CD25 marker.
