Primary Outcome Measures:
  • To determine the impact of early versus delayed initiation of treatment on the long-term disability status of patients with relapsing forms of multiple sclerosis (MS) measured by the self-reported EDSS. [ Time Frame: 15 years ]

Secondary Outcome Measures:
  • To determine the impact of early versus delayed initiation of treatment on patients' mortality, living independence, and quality of life. [ Time Frame: 15 years ]

Enrollment: 122
Study Start Date: March 2007
Study Completion Date: September 2008
Detailed Description:

The primary objective of this study is to determine the impact of early versus delayed initiation of treatment on the long-term physical status of patients with relapsing forms of MS measured by the self-reported EDSS.

Primary endpoints for this study were as follows:

  1. Changes in EDSS score from baseline for original Avonex® pivotal trial
  2. Percentage of patients with EDSS scores less than or equal to 4
  3. Percentage of patients with EDSS scores less than or equal to 6
  4. Percentage of patients with EDSS scores less than or equal to 7

Secondary endpoints were:

  1. Percentage of patients alive
  2. Percentage of patients living independently
  3. SF 36 Quality of Life status
  4. Self-reported VAS of independence with self-care
