Randomized study designed to look at the difference in relapse rates between patients remaining on their current interferon medication and those switched to Copaxone«

Clinical Details

Official title: A Multi-Center, Randomized, Single-Blind, Parallel Group Study to Compare the Efficacy, Tolerability and Safety, of Copaxone« to That of High Dose Interferon (Betaseron« or Rebif«) in the Treatment of Relapsing Multiple Sclerosis Patients

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: The primary objective of the study is to compare the total number of confirmed relapses experienced by patients randomized to maintain treatment on high dose IFN therapy compared to those who were switched to Copaxone® treatment.


Minimum age: 18 Years. Maximum age: 50 Years. Gender(s): Both.
