Overview
Brief Summary
The purpose of this study is to compare the injection site reaction and injection site pain after subcutaneous administration of either Betaferon 250µg or Rebif 44µg using different autoinjectors.
Detailed Description
Original French title of the study: Etude de phase IV, multicentrique, randomisée, ouverte, comparant les réactions et la douleur aux sites d'injection après administration sous-cutanée d'interféron β-1b (Betaferon®) ou interféron β-1a (Rebif®) pendant la période de trois mois d'initiation de la thérapie chez des patients atteints d'une forme récurrente/rémittente de sclérose en plaques. The study has previously been posted by Schering AG, Germany. Schering AG, Germany has been renamed to Bayer HealthCare AG, Germany. Bayer HealthCare AG, Germany is the sponsor of the trial.
