Title: Multicenter, Double-blind, Randomized, Parallel-group, Monotherapy, Active-control Study to Determine the Efficacy and Safety of Daclizumab High Yield Process (DAC HYP) Versus Avonex® (Interferon β 1a) in Patients With Relapsing-Remitting Multiple Sclerosis
Brief Summary: The primary study objective is to test the superiority of Daclizumab High Yield Process (DAC HYP) compared to interferon β 1a (IFN β-1a) in preventing multiple sclerosis (MS) relapse in participants with relapsing remitting multiple sclerosis.

The secondary study objectives are to test the superiority of DAC HYP compared to IFN β-1a in slowing functional decline and disability progression and maintaining quality of life in this participant population.
