Avonex pivotal trial

301 patients with rrms 18-55, >2 exacerbations over three years, EDSS 0-3.5, none within two months, placebo v. 1 treatment dose, followed for two years. Result was a decreased exacerbation rate, slightly less than betaseron, decreased progression and attack rate, but burden of disease on MRI was not significant. Barry Arnason called these results "marginal." However, he stated it was the first independent confirmation of the betaseron trial.
