Further study details as provided by Teva Pharmaceutical Industries:

Primary Outcome Measures:
  • Proportion of subjects whose high dose IFN therapy had changed in the regularly scheduled NAbs testing arm versus the Usual Care Arm [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • The nature of any therapy/management change in each arm [ Time Frame: 1 year ]
  • Reason for change in therapy/management [ Time Frame: 1 year ]

Biospecimen Retention:   Samples Without DNA
blood drawn for a Binding Antibody (BAb) and Neutralizing Antibody (NAb) test.

Enrollment: 1230
Study Start Date: July 2006
Study Completion Date: July 2009
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Regularly Scheduled NAb Testing Arm
Subjects will be scheduled for 5 study visits over the course of 12 months and any NAbs test results will be available to the investigator during the study.
Procedure: NAbs testing
blood drawn for a Binding Antibody (BAb) and Neutralizing Antibody (NAb) test.
Usual Care Arm
Subjects will be scheduled for 2 study visits over the course of 12 months and any NAbs test results will be unknown by the investigator until the conclusion of the subject's study participation.

Detailed Description:
An observational study to determine the impact of multiple neutralizing antibody (NAb) tests on treatment patterns compared to the usual care of MS patients receiving high-dose IFN therapy.
